  commit 2dc10ad81fc017837037e60439662e1b16bdffb9
  Merge: e627078 f8f8bdc
  Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>
  Date:   Wed Nov 4 14:47:13 2015 -0800

      Merge tag 'arm64-upstream' of 
git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

      Pull arm64 updates from Catalin Marinas:

       - "genirq: Introduce generic irq migration for cpu hotunplugged" patch
         merged from tip/irq/for-arm to allow the arm64-specific part to be
         upstreamed via the arm64 tree

       - CPU feature detection reworked to cope with heterogeneous systems
         where CPUs may not have exactly the same features.  The features
         reported by the kernel via internal data structures or ELF_HWCAP are
         delayed until all the CPUs are up (and before user space starts)

       - Support for 16KB pages, with the additional bonus of a 36-bit VA
         space, though the latter only depending on EXPERT

       - Implement native {relaxed, acquire, release} atomics for arm64

       - New ASID allocation algorithm which avoids IPI on roll-over, together
         with TLB invalidation optimisations (using local vs global where
         feasible)

       - KASan support for arm64

       - EFI_STUB clean-up and isolation for the kernel proper (required by
         KASan)

       - copy_{to,from,in}_user optimisations (sharing the memcpy template)

       - perf: moving arm64 to the arm32/64 shared PMU framework

       - L1_CACHE_BYTES increased to 128 to accommodate Cavium hardware

       - Support for the contiguous PTE hint on kernel mapping (16 consecutive
         entries may be able to use a single TLB entry)

       - Generic CONFIG_HZ now used on arm64

       - defconfig updates

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

      Pull s390 updates from Martin Schwidefsky:
       "There is only one new feature in this pull for the 4.4 merge window,
        most of it is small enhancements, cleanup and bug fixes:

         - Add the s390 backend for the software dirty bit tracking.  This
           adds two new pgtable functions pte_clear_soft_dirty and
           pmd_clear_soft_dirty which is why there is a hit to
           arch/x86/include/asm/pgtable.h in this pull request.

         - A series of cleanup patches for the AP bus, this includes the
           removal of the support for two outdated crypto cards (PCICC and
           PCICA).

         - The irq handling / signaling on buffer full in the runtime
           instrumentation code is dropped.

         - Some micro optimizations: remove unnecessary memory barriers for a
           couple of functions: [smb_]rmb, [smb_]wmb, atomics, bitops, and for
           spin_unlock.  Use the builtin bswap if available and make
           test_and_set_bit_lock more cache friendly.

         - Statistics and a tracepoint for the diagnose calls to the
           hypervisor.

         - The CPU measurement facility support to sample KVM guests is
           improved.

         - The vector instructions are now always enabled for user space
           processes if the hardware has the vector facility.  This simplifies
           the FPU handling code.  The fpu-internal.h header is split into fpu
           internals, api and types just like x86.

         - Cleanup and improvements for the common I/O layer.

         - Rework udelay to solve a problem with kprobe.  udelay has busy loop
           semantics but still uses an idle processor state for the wait"

      Pull networking updates from David Miller:

      Changes of note:

       1) Allow to schedule ICMP packets in IPVS, from Alex Gartrell.

       2) Provide FIB table ID in ipv4 route dumps just as ipv6 does, from
          David Ahern.

       3) Allow the user to ask for the statistics to be filtered out of
          ipv4/ipv6 address netlink dumps.  From Sowmini Varadhan.

       4) More work to pass the network namespace context around deep into
          various packet path APIs, starting with the netfilter hooks.  From
          Eric W Biederman.

       5) Add layer 2 TX/RX checksum offloading to qeth driver, from Thomas
          Richter.

       6) Use usec resolution for SYN/ACK RTTs in TCP, from Yuchung Cheng.

       7) Support Very High Throughput in wireless MESH code, from Bob
          Copeland.

       8) Allow setting the ageing_time in switchdev/rocker.  From Scott
          Feldman.

       9) Properly autoload L2TP type modules, from Stephen Hemminger.

      10) Fix and enable offload features by default in 8139cp driver, from
          David Woodhouse.

      11) Support both ipv4 and ipv6 sockets in a single vxlan device, from
          Jiri Benc.

      12) Fix CWND limiting of thin streams in TCP, from Bendik Rønning
          Opstad.

      13) Fix IPSEC flowcache overflows on large systems, from Steffen
          Klassert.

      14) Convert bridging to track VLANs using rhashtable entries rather than
          a bitmap.  From Nikolay Aleksandrov.

      15) Make TCP listener handling completely lockless, this is a major
          accomplishment.  Incoming request sockets now live in the
          established hash table just like any other socket too.

          From Eric Dumazet.

      15) Provide more bridging attributes to netlink, from Nikolay
          Aleksandrov.

      16) Use hash based algorithm for ipv4 multipath routing, this was very
          long overdue.  From Peter Nørlund.

      17) Several y2038 cures, mostly avoiding timespec.  From Arnd Bergmann.

      18) Allow non-root execution of EBPF programs, from Alexei Starovoitov.

      19) Support SO_INCOMING_CPU as setsockopt, from Eric Dumazet.  This
          influences the port binding selection logic used by SO_REUSEPORT.

      20) Add ipv6 support to VRF, from David Ahern.

      21) Add support for Mellanox Spectrum switch ASIC, from Jiri Pirko.

      24) Support multipath routes in MPLS, from Roopa Prabhu.

      25) Fix POLLOUT notification for listening sockets in AF_UNIX, from Eric
          Dumazet.

      26) Add new QED Qlogic river, from Yuval Mintz, Manish Chopra, and
          Sudarsana Kalluru.

      27) Don't fetch timestamps on AF_UNIX sockets, from Hannes Frederic
          Sowa.

      28) Support ipv6 geneve tunnels, from John W Linville.

      29) Add flood control support to switchdev layer, from Ido Schimmel.

       "Kernel side changes:

         - Improve accuracy of perf/sched clock on x86.  (Adrian Hunter)

         - Intel DS and BTS updates.  (Alexander Shishkin)

         - Intel cstate PMU support.  (Kan Liang)

         - Branch call hardware sampling support, implemented on x86 and

         - Event groups transactional interface enhancements.  (Sukadev
           Bhattiprolu)

         - Enable proper x86/intel/uncore PMU support on multi-segment PCI
           systems.  (Taku Izumi)

         - ... misc fixes and cleanups.

        The perf tooling team was very busy again with 200+ commits, the full
        diff doesn't fit into lkml size limits.  Here's an (incomplete) list
        of the tooling highlights:

        New features:

         - Change the default event used in all tools (record/top): use the
           most precise "cycles" hw counter available, i.e. when the user
           doesn't specify any event, it will try using cycles:ppp, cycles:pp,
           etc and fall back transparently until it finds a working counter.
           (Arnaldo Carvalho de Melo)

         - Integration of perf with eBPF that, given an eBPF .c source file
           (or .o file built for the 'bpf' target with clang), will get it
           automatically built, validated and loaded into the kernel via the
           sys_bpf syscall, which can then be used and seen using 'perf trace'
           and other tools.

           (Wang Nan)

        Various user interface improvements:

         - Automatic pager invocation on long help output.  (Namhyung Kim)

         - Search for more options when passing args to -h, e.g.: (Arnaldo
           Carvalho de Melo)

              $ perf report -h interface

              Usage: perf report [<options>]

               --gtk    Use the GTK2 interface
               --stdio  Use the stdio interface
               --tui    Use the TUI interface

         - Show ordered command line options when -h is used or when an
           unknown option is specified.  (Arnaldo Carvalho de Melo)

         - If options are passed after -h, show just its descriptions, not all
           options.  (Arnaldo Carvalho de Melo)

         - Implement column based horizontal scrolling in the hists browser
           (top, report), making it possible to use the TUI for things like
           'perf mem report' where there are many more columns than can fit in
           a terminal.  (Arnaldo Carvalho de Melo)

         - Enhance the error reporting of tracepoint event parsing, e.g.:

             $ oldperf record -e sched:sched_switc usleep 1
             event syntax error: 'sched:sched_switc'
                                  \___ unknown tracepoint
             Run 'perf list' for a list of valid events

           Now we get the much nicer:

             $ perf record -e sched:sched_switc ls
             event syntax error: 'sched:sched_switc'
                                  \___ can't access trace events

             Error: No permissions to read 
/sys/kernel/debug/tracing/events/sched/sched_switc
             Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug'

           And after we have those mount point permissions fixed:

             $ perf record -e sched:sched_switc ls
             event syntax error: 'sched:sched_switc'
                                  \___ unknown tracepoint

             Error: File /sys/kernel/debug/tracing/events/sched/sched_switc not 
found.
             Hint:  Perhaps this kernel misses some CONFIG_ setting to enable 
this feature?.

           I.e.  basically now the event parsing routing uses the 
strerror_open()
           routines introduced by and used in 'perf trace' work.  (Jiri Olsa)

         - Fail properly when pattern matching fails to find a tracepoint,
           i.e. '-e non:existent' was being correctly handled, with a proper
           error message about that not being a valid event, but '-e
           non:existent*' wasn't, fix it.  (Jiri Olsa)

         - Do event name substring search as last resort in 'perf list'.
           (Arnaldo Carvalho de Melo)

           E.g.:

             # perf list clock

             List of pre-defined events (to be used in -e):

              cpu-clock                                          [Software

        Intel PT hardware tracing enhancements:

         - Accept a zero --itrace period, meaning "as often as possible".  In
           the case of Intel PT that is the same as a period of 1 and a unit
           of 'instructions' (i.e.  --itrace=i1i).  (Adrian Hunter)

         - Harmonize itrace's synthesized callchains with the existing
           --max-stack tool option.  (Adrian Hunter)

         - Allow time to be displayed in nanoseconds in 'perf script'.
           (Adrian Hunter)

         - Fix potential infinite loop when handling Intel PT timestamps.
           (Adrian Hunter)

         - Slighly improve Intel PT debug logging.  (Adrian Hunter)

         - Warn when AUX data has been lost, just like when processing
           PERF_RECORD_LOST.  (Adrian Hunter)

         - Further document export-to-postgresql.py script.  (Adrian Hunter)

         - Add option to synthesize branch stack from auxtrace data.  (Adrian
           Hunter)

        Misc notable changes:

         - Switch the default callchain output mode to 'graph,0.5,caller', to
           make it look like the default for other tools, reducing the
           learning curve for people used to 'caller' based viewing.  (Arnaldo
           Carvalho de Melo)

         - various call chain usability enhancements.  (Namhyung Kim)

         - Introduce the 'P' event modifier, meaning 'max precision level,
           please', i.e.:

              $ perf record -e cycles:P usleep 1

           Is now similar to:

              $ perf record usleep 1

           Useful, for instance, when specifying multiple events.  (Jiri Olsa)

         - Add 'socket' sort entry, to sort by the processor socket in 'perf
           top' and 'perf report'.  (Kan Liang)

         - Introduce --socket-filter to 'perf report', for filtering by
           processor socket.  (Kan Liang)

         - Add new "Zoom into Processor Socket" operation in the perf hists
           browser, used in 'perf top' and 'perf report'.  (Kan Liang)

         - Allow probing on kmodules without DWARF.  (Masami Hiramatsu)

         - Fix 'perf probe -l' for probes added to kernel module functions.
           (Masami Hiramatsu)

         - Preparatory work for the 'perf stat record' feature that will allow
           generating perf.data files with counting data in addition to the
           sampling mode we have now (Jiri Olsa)

         - Update libtraceevent KVM plugin.  (Paolo Bonzini)

      atomic: remove all traces of READ_ONCE_CTRL() and atomic*_read_ctrl()

      This seems to be a mis-reading of how alpha memory ordering works, and
      is not backed up by the alpha architecture manual.  The helper functions
      don't do anything special on any other architectures, and the arguments
      that support them being safe on other architectures also argue that they
      are safe on alpha.

      Basically, the "control dependency" is between a previous read and a
      subsequent write that is dependent on the value read.  Even if the
      subsequent write is actually done speculatively, there is no way that
      such a speculative write could be made visible to other cpu's until it
      has been committed, which requires validating the speculation.

      Note that most weakely ordered architectures (very much including alpha)
      do not guarantee any ordering relationship between two loads that depend
      on each other on a control dependency:

          read A
          if (val == 1)
              read B

      because the conditional may be predicted, and the "read B" may be
      speculatively moved up to before reading the value A.  So we require the
      user to insert a smp_rmb() between the two accesses to be correct:

          read A;
          if (A == 1)
              smp_rmb()
              read B

      Alpha is further special in that it can break that ordering even if the
      *address* of B depends on the read of A, because the cacheline that is
      read later may be stale unless you have a memory barrier in between the
      pointer read and the read of the value behind a pointer:

          read ptr
          read offset(ptr)

      whereas all other weakly ordered architectures guarantee that the data
      dependency (as opposed to just a control dependency) will order the two
      accesses.  As a result, alpha needs a "smp_read_barrier_depends()" in
      between those two reads for them to be ordered.

      The coontrol dependency that "READ_ONCE_CTRL()" and "atomic_read_ctrl()"
      had was a control dependency to a subsequent *write*, however, and
      nobody can finalize such a subsequent write without having actually done
      the read.  And were you to write such a value to a "stale" cacheline
      (the way the unordered reads came to be), that would seem to lose the
      write entirely.

      So the things that make alpha able to re-order reads even more
      aggressively than other weak architectures do not seem to be relevant
      for a subsequent write.  Alpha memory ordering may be strange, but
      there's no real indication that it is *that* strange.

      Also, the alpha architecture reference manual very explicitly talks
      about the definition of "Dependence Constraints" in section 5.6.1.7,
      where a preceding read dominates a subsequent write.

      Such a dependence constraint admittedly does not impose a BEFORE (alpha
      architecture term for globally visible ordering), but it does guarantee
      that there can be no "causal loop".  I don't see how you could avoid
      such a loop if another cpu could see the stored value and then impact
      the value of the first read.  Put another way: the read and the write
      could not be seen as being out of order wrt other cpus.

      So I do not see how these "x_ctrl()" functions can currently be necessary.

      I may have to eat my words at some point, but in the absense of clear
      proof that alpha actually needs this, or indeed even an explanation of
      how alpha could _possibly_ need it, I do not believe these functions are
      called for.

      And if it turns out that alpha really _does_ need a barrier for this
      case, that barrier still should not be "smp_read_barrier_depends()".
      We'd have to make up some new speciality barrier just for alpha, along
      with the documentation for why it really is necessary.

       "In this ARM merge, we remove more lines than we add.  Changes include:

         - Enable imprecise aborts early, so that bus errors aren't masked
           until later in the boot.  This has the side effect that boot
           loaders which provoke these aborts can cause the kernel to crash
           early in boot, so we install a handler to report this event around
           the site where these are enabled.

         - Remove the buggy but impossible to enable cmpxchg syscall code.

         - Add unwinding annotations to some assembly code.

         - Add support for atomic half-word exchange for ARMv6k+.

         - Reduce ioremap() alignment for SMP/LPAE cases where we don't need
           the large alignment.

         - Addition of an "optimal" 3G configuration for systems with 1G of
           RAM.

         - Increase vmalloc space by 128M.

         - Constify some SMP operations structures, which have never been
           writable.

         - Improve ARMs dma_mmap() support for mapping DMA coherent mappings
           into userspace.

         - Fix to the NMI backtrace code in the IPI case on ARM where the
           failing CPU gets stuck for 10s waiting for its own IPI to be
           delivered.

         - Removal of legacy PM support from the AMBA bus driver.

      ide: pdc202xx_new: Replace timeval with ktime_t

      This driver uses 'struct timeval' which we are trying to remove since
      32 bit time types will break in the year 2038 by replacing it with
      ktime_t.

      This patch changes do_gettimeofday() to ktime_get() because
      ktime_get() returns a ktime_t while do_gettimeofday() returns struct
      timeval.

      This patch also uses ktime_us_delta() to get the elapsed time.

      net: dsa: mv88e6xxx: include DSA ports in VLANs

      DSA ports must be members of a VLAN in order to ensure frame bridging
      between chained switch chips.

      Thus tag them in addition to the CPU port when adding a VLAN, and skip
      them when deleting a VLAN and reporting VLAN members.

      Also use the UNMODIFIED egress policy, so that frames egress on these
      ports as they ingress, tagged or untagged.

      net/core: fix for_each_netdev_feature

      As pointed out by Nikolay and further explained by Geert, the initial
      for_each_netdev_feature macro was broken, as feature would get set outside
      of the block of code it was intended to run in, thus only ever working for
      the first feature bit in the mask. While less pretty this way, this is
      tested and confirmed functional with multiple feature bits set in
      NETIF_F_UPPER_DISABLES.

      This adds a Kconfig dependency to prevent the invalid configurations.

      Depending on the gcc version we can use builtin_bswap instead of
      architecture functions. Doing so is better than the inline assembly
      version of load reverse for two reasons:
      - the sequence of load reversed, apply constant mask, save reversed can
        be optimized to load, apply reversed mask, save
      - builtins are slightly better to optimize e.g. gcc instruction
        scheduler cannot optimize grouping on inline assemblies.

      To enable set we have to ARCH_USE_BUILTIN_BSWAP.

      s390/dasd: fix disconnected device with valid path mask

      Path verification is either done via dasd_eckd_read_conf() which is
      triggered during online processing and resume or via
      do_path_verification_work() which is triggered after path events.
      The dasd_eckd_read_conf() version added paths unconditionally and did
      not check if the path mask was empty. This led to devices having the
      disconnected stop flag set but a valid path mask. So they where not
      working although they had paths validated successfully. After a resume
      this state could even not be solved with additional paths added.

      Fix by checking for an empty path mask in dasd_eckd_read_conf() and
      clearing the device stop bits for a newly added channel path.

      s390/dasd: fix invalid PAV assignment after suspend/resume

      For a valid PAV assignment the DASD driver needs to notice possibly
      changed configuration data. Thus the failing of read configuration
      data should also fail the device restore to prevent invalid PAV
      assignment. The failed device may get restored after additional paths
      get available later on.
      If the restore fails after the device was added to the lcu alias
      handling it needs to be removed from the alias handling before exiting
      the restore function.

      mac80211: further improve "no supported rates" warning

      Allow distinguishing the non-station case from the case of a
      station without rates, by using -1 for the non-station case.
      This value cannot be reached with a station since that many
      legacy rates don't exist.

      mac80211: treat bad WMM parameters more gracefully

      As WMM is required for HT/VHT operation, treat bad WMM parameters
      more gracefully by falling back to default parameters instead of
      not using WMM assocation. This makes it possible to still use HT
      or VHT, although potentially with reduced quality of service due
      to unintended WMM parameters.

      mac80211: fixup AIFSN instead of disabling WMM

      Disabling WMM has a huge impact these days. It implies that
      HT and VHT will be disabled which means that the throughput
      will be drammatically reduced.
      Since the AIFSN is a transmission parameter, we can play a
      bit and fix it up to make it compliant with the 802.11
      specification which requires it to be at least 2.
      Increasing it from 1 to 2 will slightly reduce the
      likelyhood to get a transmission opportunity compared to
      other clients that would accept to set AIFSN=1, but at
      least it will allow HT and VHT which is a huge gain.

      cfg80211/mac80211: clarify RSSI CQM reporting requirements

      The previous patch changed mac80211 to always report an event
      after a CQM RSSI reconfiguration. Document that as expected
      behaviour in both the cfg80211 and mac80211 API.

      Currently, iwlmvm already implements that behaviour; the other
      drivers implementing CQM RSSI events may have to be changed.

      This behaviour lets userspace know what the current state is
      without relying on querying the data which is racy.

      mac80211: don't reconfigure sched scan in case of wowlan

      Scheduled scan has to be reconfigured only if wowlan wasn't
      configured, since otherwise it should continue to run (with
      the 'any' trigger) or be aborted.

      The current code will end up asking the driver to start a new
      scheduled scan without stopping the previous one, and leaking
      some memory (from the previous request.)

      Fix this by doing the abort/restart under the proper conditions.

      mac80211: call drv_stop only if driver is started

      If drv_start() fails during hw_restart, all the running
      interfaces are being closed/stopped, which results in
      drv_stop() being called, although the driver was never
      started successfully.

      This might cause drivers to perform operations on uninitialized
      memory (as they assume it was initialized on drv_start)

      Consider the local->started flag, and call the driver's stop()
      op only if drv_start() succeeded before.

      Move drv_start() and drv_stop() to driver-ops.c, as they are no
      longer simple wrappers.

      mac80211: use freezable workqueue for restart work

      Requesting hw restart during suspend might result
      in the restart work being executed after mac80211
      and the hw are suspended.

      Solve the race by simply scheduling the restart
      work on a freezable workqueue.

      Note that there can be some cases of reconfiguration
      on resume (besides the hardware restart):

      * wowlan is not configured -
          All the interfaces removed were removed on suspend,
          and drv_stop() was called. At this point the driver
          shouldn't expect for hw_restart anyway, so we can
          simply cancel it (on resume).

      * wowlan is configured, drv_resume() == 1
          There is no definitive expected behavior in this case,
          as each driver might have different expectations (e.g.
          setting some flags on suspend/restart vs. not handling
          spurious recovery).
          For now, simply let the hw_restart work run again after
          resume, and hope the driver will handle it well (or at
          least initiate another hw restart).

      net: phy: fix a bug in get_phy_c45_ids

      When probing devices-in-package for a c45 phy, device zero is the last
      device to probe, however, if driver reads 0 from device zero,
      c45_ids->devices_in_package is set to '0', the loop condition of probing
      will be matched again, see codes below:

      for (i = 1;i < num_ids && c45_ids->devices_in_package == 0;i++)

      driver will run in a dead loop.

      This patch restructures the bug and confusing loop, it provides a helper
      function get_phy_c45_devs_in_pkg which to read devices-in-package 
registers
      of a MMD, and rewrites the loop with using the helper function.

      net/core: generic support for disabling netdev features down stack

      There are some netdev features, which when disabled on an upper device,
      such as a bonding master or a bridge, must be disabled and cannot be
      re-enabled on underlying devices.

      This is a rework of an earlier more heavy-handed appraoch, which simply
      disables and prevents re-enabling of netdev features listed in a new
      define in include/net/netdev_features.h, NETIF_F_UPPER_DISABLES. Any upper
      device that disables a flag in that feature mask, the disabling will
      propagate down the stack, and any lower device that has any upper device
      with one of those flags disabled should not be able to enable said flag.

      Initially, only LRO is included for proof of concept, and because this
      code effectively does the same thing as dev_disable_lro(), though it will
      also activate from the ethtool path, which was one of the goals here.

      [root@dell-per730-01 ~]# ethtool -k bond0 |grep large
      large-receive-offload: on
      [root@dell-per730-01 ~]# ethtool -k p5p1 |grep large
      large-receive-offload: on
      [root@dell-per730-01 ~]# ethtool -K bond0 lro off
      [root@dell-per730-01 ~]# ethtool -k bond0 |grep large
      large-receive-offload: off
      [root@dell-per730-01 ~]# ethtool -k p5p1 |grep large
      large-receive-offload: off

      dmesg dump:

      [ 1033.277986] bond0: Disabling feature 0x0000000000008000 on lower dev 
p5p2.
      [ 1034.067949] bnx2x 0000:06:00.1 p5p2: using MSI-X  IRQs: sp 74  fp[0]

      [ 1034.753612] bond0: Disabling feature 0x0000000000008000 on lower dev

64 ... fp[7] 71

      This has been successfully tested with bnx2x, qlcnic and netxen network
      cards as slaves in a bond interface. Turning LRO on or off on the master
      also turns it on or off on each of the slaves, new slaves are added with
      LRO in the same state as the master, and LRO can't be toggled on the
      slaves.

      Also, this should largely remove the need for dev_disable_lro(), and most,
      if not all, of its call sites can be replaced by simply making sure
      NETIF_F_LRO isn't included in the relevant device's feature flags.

      Note that this patch is driven by bug reports from users saying it was
      confusing that bonds and slaves had different settings for the same
      features, and while it won't be 100% in sync if a lower device doesn't
      support a feature like LRO, I think this is a good step in the right
      direction.

      sfc: push partner queue for skb->xmit_more

      When the IP stack passes SKBs the sfc driver puts them in 2 different TX
      queues (called partners), one for checksummed and one for not checksummed.
      If the SKB has xmit_more set the driver will delay pushing the work to the
      NIC.

      When later it does decide to push the buffers this patch ensures it also
      pushes the partner queue, if that also has any delayed work. Before this
      fix the work in the partner queue would be left for a long time and cause
      a netdev watchdog.

      ====================
      re-org actor admin/oper key updates

      I was observing machines entering into weird LACP state when the
      partner is in passive mode. This issue is not because of the partners
      in passive state but probably because of some operational key update
      which is pushing the state-machine is that weird state. This was
      happening randomly on about 1% of the machine (when the sample size
      is a large set of machines with a variety of NICs/ports bonded).

      In this patch-series I'm attempting to unify the logic of actor-key
      / operational-key changes to one place to avoid possible errors in
      update. Also this eliminates the need for the event-handler to decide
      if the key needs update.

      After this patch-set none of the machines (from same sample set) were
      exhibiting LACP-weirdness that was observed earlier.

      bonding: unify all places where actor-oper key needs to be updated.

      actor_admin, and actor_oper key is changed at multiple locations in
      the code. This patch brings all those updates into one location in
      an attempt to avoid possible inconsistent updates causing LACP state
      machine to go in weird state.

      The unified place is ad_update_actor_key() with simple state-machine

      bpf: add sample usages for persistent maps/progs

      This patch adds a couple of stand-alone examples on how BPF_OBJ_PIN
      and BPF_OBJ_GET commands can be used.

      Example with maps:

        # ./fds_example -F /sys/fs/bpf/m -P -m -k 1 -v 42
        bpf: map fd:3 (Success)
        bpf: pin ret:(0,Success)
        bpf: fd:3 u->(1:42) ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/m -G -m -k 1
        bpf: get fd:3 (Success)
        bpf: fd:3 l->(1):42 ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/m -G -m -k 1 -v 24
        bpf: get fd:3 (Success)
        bpf: fd:3 u->(1:24) ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/m -G -m -k 1
        bpf: get fd:3 (Success)
        bpf: fd:3 l->(1):24 ret:(0,Success)

        # ./fds_example -F /sys/fs/bpf/m2 -P -m
        bpf: map fd:3 (Success)
        bpf: pin ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/m2 -G -m -k 1
        bpf: get fd:3 (Success)
        bpf: fd:3 l->(1):0 ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/m2 -G -m
        bpf: get fd:3 (Success)

      Example with progs:

        # ./fds_example -F /sys/fs/bpf/p -P -p
        bpf: prog fd:3 (Success)
        bpf: pin ret:(0,Success)
        bpf sock:4 <- fd:3 attached ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/p -G -p
        bpf: get fd:3 (Success)
        bpf: sock:4 <- fd:3 attached ret:(0,Success)

        # ./fds_example -F /sys/fs/bpf/p2 -P -p -o ./sockex1_kern.o

      bpf: add support for persistent maps/progs

      This work adds support for "persistent" eBPF maps/programs. The term
      "persistent" is to be understood that maps/programs have a facility
      that lets them survive process termination. This is desired by various
      eBPF subsystem users.

      Just to name one example: tc classifier/action. Whenever tc parses
      the ELF object, extracts and loads maps/progs into the kernel, these
      file descriptors will be out of reach after the tc instance exits.
      So a subsequent tc invocation won't be able to access/relocate on this
      resource, and therefore maps cannot easily be shared, f.e. between the
      ingress and egress networking data path.

      The current workaround is that Unix domain sockets (UDS) need to be
      instrumented in order to pass the created eBPF map/program file
      descriptors to a third party management daemon through UDS' socket
      passing facility. This makes it a bit complicated to deploy shared
      eBPF maps or programs (programs f.e. for tail calls) among various
      processes.

      We've been brainstorming on how we could tackle this issue and various
      approches have been tried out so far, which can be read up further in
      the below reference.

      The architecture we eventually ended up with is a minimal file system
      that can hold map/prog objects. The file system is a per mount namespace
      singleton, and the default mount point is /sys/fs/bpf/. Any subsequent
      mounts within a given namespace will point to the same instance. The
      file system allows for creating a user-defined directory structure.
      The objects for maps/progs are created/fetched through bpf(2) with
      two new commands (BPF_OBJ_PIN/BPF_OBJ_GET). I.e. a bpf file descriptor
      along with a pathname is being passed to bpf(2) that in turn creates
      (we call it eBPF object pinning) the file system nodes. Only the pathname
      is being passed to bpf(2) for getting a new BPF file descriptor to an
      existing node. The user can use that to access maps and progs later on,
      through bpf(2). Removal of file system nodes is being managed through
      normal VFS functions such as unlink(2), etc. The file system code is
      kept to a very minimum and can be further extended later on.

      The next step I'm working on is to add dump eBPF map/prog commands
      to bpf(2), so that a specification from a given file descriptor can
      be retrieved. This can be used by things like CRIU but also applications
      can inspect the meta data after calling BPF_OBJ_GET.

      Big thanks also to Alexei and Hannes who significantly contributed
      in the design discussion that eventually let us end up with this
      architecture here.

      bpf: consolidate bpf_prog_put{, _rcu} dismantle paths

      We currently have duplicated cleanup code in bpf_prog_put() and
      bpf_prog_put_rcu() cleanup paths. Back then we decided that it was
      not worth it to make it a common helper called by both, but with
      the recent addition of resource charging, we could have avoided
      the fix in commit ac00737f4e81 ("bpf: Need to call 
bpf_prog_uncharge_memlock
      from bpf_prog_put") if we would have had only a single, common path.
      We can simplify it further by assigning aux->prog only once during
      allocation time.

      bpf: align and clean bpf_{map,prog}_get helpers

      Add a bpf_map_get() function that we're going to use later on and
      align/clean the remaining helpers a bit so that we have them a bit
      more consistent:

        - __bpf_map_get() and __bpf_prog_get() that both work on the fd
          struct, check whether the descriptor is eBPF and return the
          pointer to the map/prog stored in the private data.

          Also, we can return f.file->private_data directly, the function
          signature is enough of a documentation already.

        - bpf_map_get() and bpf_prog_get() that both work on u32 user fd,
          call their respective __bpf_map_get()/__bpf_prog_get() variants,
          and take a reference.

      net: fix percpu memory leaks

      This patch fixes following problems :

      1) percpu_counter_init() can return an error, therefore
        init_frag_mem_limit() must propagate this error so that
        inet_frags_init_net() can do the same up to its callers.

      2) If ip[46]_frags_ns_ctl_register() fail, we must unwind
         properly and free the percpu_counter.

      Without this fix, we leave freed object in percpu_counters
      global list (if CONFIG_HOTPLUG_CPU) leading to crashes.

      This bug was detected by KASAN and syzkaller tool
      (http://github.com/google/syzkaller)

      The lt4112 is a HP branded Huawei me906e modem. Like other Huawei
      modems, it does not have a fixed interface to function mapping.
      Instead it uses a Huawei specific scheme: functions are mapped by
      subclass and protocol.

      However, the HP vendor ID is used for modems from many different
      manufacturers using different schemes, so we cannot apply a generic
      vendor rule like we do for the Huawei vendor ID.

      Replace the previous lt4112 entry pointing to an arbitrary interface
      number with a device specific subclass + protocol match.

      Merge tag 'gpio-v4.4-1' of 
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

      Pull GPIO updates from Linus Walleij:
       "Here is the bulk of GPIO changes for the v4.4 development cycle.

        The only changes hitting outside drivers/gpio are in the pin control
        subsystem and these seem to have settled nicely in linux-next.

        Development mistakes and catfights are nicely documented in the
        reverts as you can see.  The outcome of the ABI fight is that we're
        working on a chardev ABI for GPIO now, where hope to show results for
        the v4.5 kernel.

        Summary of changes:

        GPIO core:
         - Define and handle flags for open drain/open collector and open
           source/open emitter, also know as "single-ended" configurations.
         - Generic request/free operations that handle calling out to the
           (optional) pin control backend.
         - Some refactoring related to an ABI change that did not happen, yet
           provide useful.
         - Added a real-time compliance checklist.  Many GPIO chips have
           irqchips, and need to think this over with the RT patches going
           upstream.
         - Restructure, fix and clean up Kconfig menus a bit.

        New drivers:
         - New driver for AMD Promony.
         - New driver for ACCES 104-IDIO-16, a port-mapped I/O card,
           ISA-style.  Very retro.

        Subdriver changes:
         - OMAP changes to handle real time requirements.
         - Handle trigger types for edge and level IRQs on PL061 properly.  As
           this hardware is very common it needs to set a proper example for
           others to follow.
         - Some container_of() cleanups.
         - Delete the unused MSM driver in favor of the driver that is
           embedded inside the pin control driver.
         - Cleanup of the ath79 GPIO driver used by many, many OpenWRT router
           targets.
         - A consolidated IT87xx driver replacing the earlier very specific
           IT8761e driver.
         - Handle the TI TCA9539 in the PCA953x driver.  Also handle ACPI
           devices in this subdriver.
         - Drop xilinx arch dependencies as these FPGAs seem to profilate over
           a few different architectures.  MIPS and ARM come to mind"

      sh_eth: fix uninitialized arrays in sh_eth_ring_init()

      sh_eth_ring_free()  called in the sh_eth_ring_init()'s error path expects
      the arrays pointed  to  by 'sh_eth_private::[rt]x_skbuff' to be 
initialized
      with NULLs but they are allocated with just kmalloc_array() and so are 
left
      filled with random data. Use kcalloc() instead.

      net: dsa: mv88e6xxx: lookup switch name

      All the mv88e6xxx drivers use the exact same code in their probe
      function to lookup the switch name given its ID. Thus introduce a
      mv88e6xxx_switch_id structure and a mv88e6xxx_lookup_name function in
      the common mv88e6xxx code.

      In the meantime make __mv88e6xxx_reg_{read,write} static since we do not
      need to expose these low-level r/w routines anymore.

      This is a set from Ido which takes care of one failure path error in
      nbp_vlan_init (patch 1) and a few comment errors (patch 2).
      I must admit I didn't expect the port init continues after a vlan init
      failure but should've checked to make sure. Thanks to Ido for catching
      these!

      bridge: vlan: Use correct flag name in comment

      The flag used to indicate if a VLAN should be used for filtering - as
      opposed to context only - on the bridge itself (e.g. br0) is called
      'brentry' and not 'brvlan'.

      bridge: vlan: Prevent possible use-after-free

      When adding a port to a bridge we initialize VLAN filtering on it. We do
      not bail out in case an error occurred in nbp_vlan_init, as it can be
      used as a non VLAN filtering bridge.

      However, if VLAN filtering is required and an error occurred in
      nbp_vlan_init, we should set vlgrp to NULL, so that VLAN filtering
      functions (e.g. br_vlan_find, br_get_pvid) will know the struct is
      invalid and will not try to access it.

      tcp/dccp: fix ireq->pktopts race

      IPv6 request sockets store a pointer to skb containing the SYN packet
      to be able to transfer it to full blown socket when 3WHS is done
      (ireq->pktopts -> np->pktoptions)

      As explained in commit 5e0724d027f0 ("tcp/dccp: fix hashdance race for
      passive sessions"), we must transfer the skb only if we won the
      hashdance race, if multiple cpus receive the 'ack' packet completing
      3WHS at the same time.

      Fixes: e994b2f0fb92 ("tcp: do not lock listener to process SYN packets")
      Fixes: 079096f103fa ("tcp/dccp: install syn_recv requests into ehash 
table")

      RDS: convert bind hash table to re-sizable hashtable

      To further improve the RDS connection scalabilty on massive systems
      where number of sockets grows into tens of thousands  of sockets, there
      is a need of larger bind hashtable. Pre-allocated 8K or 16K table is
      not very flexible in terms of memory utilisation. The rhashtable
      infrastructure gives us the flexibility to grow the hashtbable based
      on use and also comes up with inbuilt efficient bucket(chain) handling.

      Merge tag 'pinctrl-v4.4-1' of 
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

      Pull pin control updates from Linus Walleij:
       "This is the big bulk of pin control changes for the v4.4 kernel
        development cycle.  Development pace is high in pin control again this
        merge window.  28 contributors, 83 patches.

        It hits a few sites outside the pin control subsystem:

         - Device tree bindings in Documentation (as usual)
         - MAINTAINERS
         - drivers/base/* for the "init" state handling by Doug Anderson.
           This has been ACKed by Greg.
         - drivers/usb/renesas_usbhs/rcar2.c, for a dependent Renesas change
           in the USB subsystem.  This has been ACKed by both Greg and Felipe.
         - arch/arm/boot/dts/sama5d2.dtsi - this should ideally have gone
           through the ARM SoC tree but ended up here.

        This time I am using Geert Uytterhoeven as submaintainer for SH PFC
        since the are three-four people working in parallel with new Renesas
        ASICs.

        Summary of changes:

        Infrastructure:

         - Doug Anderson wrote a patch adding an "init" state different from
           the "default" state for pin control state handling in the core
           framework.  This is applied before the driver's probe() call if
           defined and takes precedence over "default".  If both are defined,
           "init" will be applied *before* probe() and "default" will be
           applied *after* probe().

        Significant subdriver improvements:

         - SH PFC is switched to getting GPIO ranges from the device tree
           ranges property on DT platforms.
         - Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all modernized.
         - Got rid of SH PFC hardcoded IRQ numbers.
         - Allwinner sunxi external interrupt through the "r" controller.
         - Moved the Cygnus driver to use DT-provided GPIO ranges.

        New drivers:

         - Atmel PIO4 pin controller for the SAMA4D2 family

        New subdrivers:

         - Rockchip RK3036 subdriver
         - Renesas SH PFC R8A7795 subdriver
         - Allwinner sunxi A83T PIO subdriver
         - Freescale i.MX7d iomux lpsr subdriver
         - Marvell Berlin BG4CT subdriver
         - SiRF Atlas 7 step B SoC subdriver
         - Intel Broxton SoC subdriver

        Apart from this, the usual slew if syntactic and semantic fixes"

      net: encx24j600: Fix SPI driver module autoload

      Recently I've been trying to fix module autoloading for all SPI drivers 
and
      found that the encx24j600 driver does not fill module alias information 
due
      missing a MODULE_DEVICE_TABLE() so module autload won't work and the 
driver
      Kconfig symbol is tristate which means the driver can be built as a 
module.

      But also the SPI id table is not correctly defined so this series fixes 
both

      net: encx24j600: Fix SPI id table definition

      A driver's SPI id table is expected to be an array of struct spi_device_id
      that ends with a zero-initialized sentinel entry. But this driver defines
      the table as a single struct spi_device_id and sets .id_table to a pointer
      to this struct.

      But spi_match_id() has a loop that iterates while the struct spi_device_id
      .name[0] is not NULL, so not having a sentinel can cause a NULL pointer
      deference error.

      This patch defines the SPI id table correctly as all other SPI drivers do.

      ipv4: use l4 hash for locally generated multipath flows

      This patch changes how the multipath hash is computed for locally
      generated flows: now the hash comprises l4 information.

      This allows better utilization of the available paths when the existing
      flows have the same source IP and the same destination IP: with l3 hash,
      even when multiple connections are in place simultaneously, a single path
      will be used, while with l4 hash we can use all the available paths.

      v2 changes:
      - use get_hash_from_flowi4() instead of implementing just another l4 hash
        function

      Since we now have a gpiolib driver, remove this code:

      The gpio-etraxfs driver (along with things like gpio-keys-polled for
      polling support) replaces the GIO driver implementations in mach-a3 and
      mach-fs.  The various generic external chip drivers replace the "virtual

      mm: get rid of 'vmalloc_info' from /proc/meminfo

      It turns out that at least some versions of glibc end up reading
      /proc/meminfo at every single startup, because glibc wants to know the
      amount of memory the machine has.  And while that's arguably insane,
      it's just how things are.

      And it turns out that it's not all that expensive most of the time, but
      the vmalloc information statistics (amount of virtual memory used in the
      vmalloc space, and the biggest remaining chunk) can be rather expensive
      to compute.

      The 'get_vmalloc_info()' function actually showed up on my profiles as
      4% of the CPU usage of "make test" in the git source repository, because
      the git tests are lots of very short-lived shell-scripts etc.

      It turns out that apparently this same silly vmalloc info gathering
      shows up on the facebook servers too, according to Dave Jones.  So it's
      not just "make test" for git.

      We had two patches to just cache the information (one by me, one by
      Ingo) to mitigate this issue, but the whole vmalloc information of of
      rather dubious value to begin with, and people who *actually* want to
      know what the situation is wrt the vmalloc area should just look at the
      much more complete /proc/vmallocinfo instead.

      In fact, according to my testing - and perhaps more importantly,
      according to that big search engine in the sky: Google - there is
      nothing out there that actually cares about those two expensive fields:
      VmallocUsed and VmallocChunk.

      So let's try to just remove them entirely.  Actually, this just removes
      the computation and reports the numbers as zero for now, just to try to
      be minimally intrusive.

      If this breaks anything, we'll obviously have to re-introduce the code
      to compute this all and add the caching patches on top.  But if given
      the option, I'd really prefer to just remove this bad idea entirely
      rather than add even more code to work around our historical mistake
      that likely nobody really cares about.

      Merge branch 'fs-file-descriptor-optimization'

      Merge file descriptor allocation speedup.

      Eric Dumazet has a test-case for a fairly common network deamon load
      pattern: openign and closing a lot of sockets that each have very little
      work done on them.  It turns out that in that case, the cost of just
      finding the correct file descriptor number can be a dominating factor.

      We've long had a trivial optimization for allocating file descriptors
      sequentially, but that optimization ends up being not very effective
      when other file descriptors are being closed concurrently, and the fd
      patterns are not some simple FIFO pattern.  In such cases we ended up
      spending a lot of time just scanning the bitmap of open file descriptors
      in order to find the next file descriptor number to open.

      This trivial patch-series mitigates that by simply introducing a
      second-level bitmap of which words in the first bitmap are already fully
      allocated.  That cuts down the cost of scanning by an order of magnitude
      in some pathological (but realistic) cases.

      The second patch is an even more trivial patch to avoid unnecessarily
      dirtying the cacheline for the close-on-exec bit array that normally
      ends up being all empty.

      Use 64-bit timekeeping

      This patch changes the use of struct timespec in
      dccp_probe to use struct timespec64 instead. timespec uses a 32-bit
      seconds field which will overflow in the year 2038 and beyond. timespec64
      uses a 64-bit seconds field. Note that the correctness of the code isn't
      changed, since the original code only uses the timestamps to compute a
      small elapsed interval. This patch is part of a larger attempt to remove
      instances of 32-bit timekeeping structures (timespec, timeval, time_t)
      from the kernel so it is easier to identify where the real 2038 issues
      are.

      ipv4: update RTNH_F_LINKDOWN flag on UP event

      When nexthop is part of multipath route we should clear the
      LINKDOWN flag when link goes UP or when first address is added.
      This is needed because we always set LINKDOWN flag when DEAD flag
      was set but now on UP the nexthop is not dead anymore. Examples when
      LINKDOWN bit can be forgotten when no NETDEV_CHANGE is delivered:

      - link goes down (LINKDOWN is set), then link goes UP and device
      shows carrier OK but LINKDOWN remains set

      - last address is deleted (LINKDOWN is set), then address is
      added and device shows carrier OK but LINKDOWN remains set

      Steps to reproduce:
      modprobe dummy
      ifconfig dummy0 192.168.168.1 up

      here add a multipath route where one nexthop is for dummy0:

      ip route add 1.2.3.4 nexthop dummy0 nexthop SOME_OTHER_DEVICE
      ifconfig dummy0 down
      ifconfig dummy0 up

      now ip route shows nexthop that is not dead. Now set the sysctl var:

      echo 1 > /proc/sys/net/ipv4/conf/dummy0/ignore_routes_with_linkdown

      now ip route will show a dead nexthop because the forgotten
      RTNH_F_LINKDOWN is propagated as RTNH_F_DEAD.

      When fib_netdev_event calls fib_disable_ip on NETDEV_DOWN event

      VSOCK: define VSOCK_SS_LISTEN once only

      The SS_LISTEN socket state is defined by both af_vsock.c and
      vmci_transport.c.  This is risky since the value could be changed in one
      file and the other would be out of sync.

      Rename from SS_LISTEN to VSOCK_SS_LISTEN since the constant is not part
      of enum socket_state (SS_CONNECTED, ...).  This way it is clear that the
      constant is vsock-specific.

      The big text reflow in af_vsock.c was necessary to keep to the maximum
      line length.  Text is unchanged except for s/SS_LISTEN/VSOCK_SS_LISTEN/.

      net: smsc911x: Fix crash if loopback test fails

      On certain hardware in certain situations loopback test fails and the
      driver gets removed. During mdiobus_unregister() instance of PHY driver
      gets disposed. But by this time it has already been started using
      phy_connect_direct().

      PHY driver uses DELAYED_WORK in order to maintain its state. Attempting
      to dispose the driver without calling phy_disconnect() causes deallocation
      of DELAYED_WORK being active. This shortly causes a bad crash in timer
      code.

      The problem can be discovered by enabling CONFIG_DEBUG_OBJECTS_TIMERS and
      CONFIG_DEBUG_OBJECTS_FREE

      tipc: linearize arriving NAME_DISTR and LINK_PROTO buffers

      Testing of the new UDP bearer has revealed that reception of
      NAME_DISTRIBUTOR, LINK_PROTOCOL/RESET and LINK_PROTOCOL/ACTIVATE
      message buffers is not prepared for the case that those may be
      non-linear.

      We now linearize all such buffers before they are delivered up to the
      generic reception layer.

      In order for the commit to apply cleanly to 'net' and 'stable', we do
      the change in the function tipc_udp_recv() for now. Later, we will post
      a commit to 'net-next' moving the linearization to generic code, in
      tipc_named_rcv() and tipc_link_proto_rcv().

      net: clean up interactions of CHECKSUM_PARTIAL and fragmentation

      This series fixes wrong checksums on the wire for IPv4 and IPv6. Large

      gpio: fix up SPI submenu

      - Relax dependencies on SPI_MASTER for drivers in the SPI menu
        that already has this dependency.
      - Move out the expander that would be hidden for I2C access if
        SPI_MASTER was not selected. Tentatively create a separate
        menu for this.
      - Move the ZX SoC driver to memory-mapped drivers, this must be

      vfs: conditionally clear close-on-exec flag

      We clear the close-on-exec flag when opening and closing files, and the
      bit was almost always already clear before.  Avoid dirtying the
      cacheline if the clearning isn't necessary.  That avoids unnecessary
      cacheline dirtying and bouncing in multi-socket environments.

      Eric Dumazet has a file descriptor benchmark that goes 4% faster from
      this on his two-socket machine.  It's probably partly superlinear
      improvement due to getting slightly less spinlock contention on the
      file_lock spinlock due to less work in the critical section.

      And Eric Dumazet has a somewhat realistic multithreaded microbenchmark
      that opens and closes a lot of sockets with minimal work per socket.

      This patch largely fixes it.  We keep a 2nd-level bitmap of the open
      file bitmaps, showing which words are already full.  So then we can
      traverse that second-level bitmap to efficiently skip already allocated
      file descriptors.

      On his benchmark, this improves performance by up to an order of
      magnitude, by avoiding the excessive open file bitmap scanning.

      gpio / ACPI: Allow shared GPIO event to be read via operation region

      In Microsoft Surface3 the GPIO detecting lid state is shared between GPIO
      event and operation region. Below is simplied version of the DSDT from
      Surface3 including relevant parts:

          Scope (GPO0)
          {
              Name (_AEI, ResourceTemplate ()
              {
                  GpioInt (Edge, ActiveBoth, Shared, PullNone, 0x0000,
                      "\\_SB.GPO0", 0x00, ResourceConsumer, ,
                      )
                      {   // Pin list
                          0x004C
                      }
              })

              OperationRegion (GPOR, GeneralPurposeIo, Zero, One)
              Field (GPOR, ByteAcc, NoLock, Preserve)
              {
                  Connection (
                      GpioIo (Shared, PullNone, 0x0000, 0x0000,
                          IoRestrictionNone, "\\_SB.GPO0", 0x00,
                          ResourceConsumer,,)
                          {   // Pin list
                              0x004C
                          }
                  ),
                  HELD,   1
              }

              Method (_E4C, 0, Serialized)  // _Exx: Edge-Triggered GPE
              {
                  If ((HELD == One))
                  {
                      ^^LID.LIDB = One
                  }
                  Else
                  {
                      ^^LID.LIDB = Zero
                      Notify (LID, 0x80) // Status Change
                  }

                  Notify (^^PCI0.SPI1.NTRG, One) // Device Check
              }
          }

      When GPIO 0x4c changes we call ASL method _E4C which tries to read HELD
      field (the same GPIO). This triggers following error on the console:

          ACPI Error: Method parse/execution failed [\_SB.GPO0._E4C]
              (Node ffff88013f4b4438), AE_ERROR (20150930/psparse-542)

      The error happens because ACPI GPIO operation region handler
      (acpi_gpio_adr_space_handler()) tries to acquire the very same GPIO which
      returns an error (-EBUSY) because the GPIO is already reserved for the 
GPIO
      event.

      Fix this so that we "borrow" the event GPIO if we find the GPIO belongs to
      an event. Allow this only for GPIOs that are read.

      To be able to go through acpi_gpio->events list for operation region 
access
      we need to make sure the list is properly initialized whenever GPIO chip 
is
      registered.

      Revert "md: allow a partially recovered device to be hot-added to an 
array."

      This reverts commit 7eb418851f3278de67126ea0c427641ab4792c57.

      This commit is poorly justified, I can find not discusison in email,
      and it clearly causes a problem.

      If a device which is being recovered fails and is subsequently
      re-added to an array, there could easily have been changes to the
      array *before* the point where the recovery was up to.  So the
      recovery must start again from the beginning.

      If a spare is being recovered and fails, then when it is re-added we
      really should do a bitmap-based recovery up to the recovery-offset,
      and then a full recovery from there.  Before this reversion, we only
      did the "full recovery from there" which is not corect.  After this
      reversion with will do a full recovery from the start, which is safer
      but not ideal.

      It will be left to a future patch to arrange the two different styles
      of recovery.

      md/raid5: fix locking in handle_stripe_clean_event()

      After commit 566c09c53455 ("raid5: relieve lock contention in 
get_active_stripe()")
      __find_stripe() is called under conf->hash_locks + hash.
      But handle_stripe_clean_event() calls remove_hash() under
      conf->device_lock.

      Under some cirscumstances the hash chain can be circuited,
      and we get an infinite loop with disabled interrupts and locked hash
      lock in __find_stripe(). This leads to hard lockup on multiple CPUs
      and following system crash.

      I was able to reproduce this behavior on raid6 over 6 ssd disks.
      The devices_handle_discard_safely option should be set to enable trim
      support. The following script was used:

      for i in `seq 1 32`; do
          dd if=/dev/zero of=large$i bs=10M count=100 &
      done

      rbd: require stable pages if message data CRCs are enabled

      rbd requires stable pages, as it performs a crc of the page data before
      they are send to the OSDs.

      But since kernel 3.9 (patch 1d1d1a767206fbe5d4c69493b7e6d2a8d08cc0a0
      "mm: only enforce stable page writes if the backing device requires
      it") it is not assumed anymore that block devices require stable pages.

      This patch sets the necessary flag to get stable pages back for rbd.

      In a ceph installation that provides multiple ext4 formatted rbd
      devices "bad crc" messages appeared regularly (ca 1 message every 1-2
      minutes on every OSD that provided the data for the rbd) in the
      OSD-logs before this patch. After this patch this messages are pretty
      much gone (only ca 1-2 / month / OSD).

      Now that we added special handling to the C files in libstub, move
      the one remaining arm64 specific EFI stub C file to libstub as
      well, so that it gets the same treatment. This should prevent future
      changes from resulting in binaries that may execute incorrectly in

      With efi-entry.S the only remaining EFI stub source file under

      ====================
      pull request (net-next): ipsec-next 2015-10-30

      1) The flow cache is limited by the flow cache limit which
         depends on the number of cpus and the xfrm garbage collector
         threshold which is independent of the number of cpus. This
         leads to the fact that on systems with more than 16 cpus
         we hit the xfrm garbage collector limit and refuse new
         allocations, so new flows are dropped. On systems with 16
         or less cpus, we hit the flowcache limit. In this case, we
         shrink the flow cache instead of refusing new flows.

         We increase the xfrm garbage collector threshold to INT_MAX
         to get the same behaviour, independent of the number of cpus.

      2) Fix some unaligned accesses on sparc systems.
         From Sowmini Varadhan.

      3) Fix some header checks in _decode_session4. We may call
         pskb_may_pull with a negative value converted to unsigened
         int from pskb_may_pull. This can lead to incorrect policy
         lookups. We fix this by a check of the data pointer position
         before we call pskb_may_pull.

      4) Reload skb header pointers after calling pskb_may_pull
         in _decode_session4 as this may change the pointers into
         the packet.

      5) Add a missing statistic counter on inner mode errors.

      ====================
      NFC 4.4 pull request

      This is the NFC pull request for 4.4.

      It's a bit bigger than usual, the 3 main culprits being:

      - A new driver for Intel's Fields Peak NCI chipset. In order to
        support this chipset we had to export a few NCI routines and
        extend the driver NCI ops to not only support proprietary
        commands but also core ones.

      - Support for vendor commands for both STM drivers, st-nci
        and st21nfca. Those vendor commands allow to run factory tests
        through the NFC netlink interface.

      - New i2c and SPI support for the Marvell driver, together with
        firmware download support for this driver's core.

      Besides that we also have:

      - A few file renames in the STM drivers, to keep the naming
        consistent between drivers.

      - Some improvements and fixes on the NCI HCI layer, mostly to
        properly reach a secure element over a legacy HCI link.

      - A few fixes for the s3fwrn5 and trf7970a drivers.

      Document that IRQ_NONE should be returned when IRQ not actually handled

      Our IRQ storm detection works when an interrupt handler returns
      IRQ_NONE for thousands of consecutive interrupts in a second. It
      doesn't hurt to occasionally return IRQ_NONE when the interrupt is
      actually genuine.

      Drivers should only be returning IRQ_HANDLED if they have actually
      *done* something to stop an interrupt from happening â?? it doesn't just
      mean "this really *was* my device".

      ipv6: recreate ipv6 link-local addresses when increasing MTU over 
IPV6_MIN_MTU

      This change makes it so that we reinitialize the interface if the MTU is
      increased back above IPV6_MIN_MTU and the interface is up.

      drivers: xgene: Add support RGMII TX/RX delay configuration

      X-Gene RGMII ethernet controller has a RGMII bridge that performs the
      task of converting the RGMII signal {RX_CLK,RX_CTL, RX_DATA[3:0]} from
      PHY to GMII signal {RX_DV,RX_ER,RX_DATA[7:0]} and vice versa.  This

      bridge: set is_local and is_static before fdb entry is added to the fdb 
hashtable

      Problem Description:
      We can add fdbs pointing to the bridge with NULL ->dst but that has a
      few race conditions because br_fdb_insert() is used which first creates
      the fdb and then, after the fdb has been published/linked, sets
      "is_local" to 1 and in that time frame if a packet arrives for that fdb
      it may see it as non-local and either do a NULL ptr dereference in
      br_forward() or attach the fdb to the port where it arrived, and later
      br_fdb_insert() will make it local thus getting a wrong fdb entry.
      Call chain br_handle_frame_finish() -> br_forward():
      But in br_handle_frame_finish() in order to call br_forward() the dst
      should not be local i.e. skb != NULL, whenever the dst is
      found to be local skb is set to NULL so we can't forward it,
      and here comes the problem since it's running only
      with RCU when forwarding packets it can see the entry before "is_local"
      is set to 1 and actually try to dereference NULL.
      The main issue is that if someone sends a packet to the switch while
      it's adding the entry which points to the bridge device, it may
      dereference NULL ptr. This is needed now after we can add fdbs
      pointing to the bridge.  This poses a problem for
      br_fdb_update() as well, while someone's adding a bridge fdb, but
      before it has is_local == 1, it might get moved to a port if it comes
      as a source mac and then it may get its "is_local" set to 1

      This patch changes fdb_create to take is_local and is_static as
      arguments to set these values in the fdb entry before it is added to the
      hash. Also adds null check for port in br_forward.

      tools build: Fix libiberty feature detection

      Any CFLAGS or LDFLAGS set by the user need to be passed to the feature
      build command.  This many include for example -I or -L to point to
      libraries and include files in custom paths.

      In most of the test-*.bin rules in build/feature/Makefile, we use the 
BUILD
      macro which always sends in CFLAGS and LDFLAGS.  The libiberty build line
      however doesn't use the BUILD macro and thus needs to send in CFLAGS and
      LDFLAGS explicitly.  Without this, when using custom CFLAGS/LDFLAGS, 
libiberty
      fails to be detected and the perf link fails with something like:

         LINK     perf
        libbfd.a(bfd.o): In function `bfd_errmsg':
        bfd.c:(.text+0x168): undefined reference to `xstrerror'

      perf tools: Compile scriptlets to BPF objects when passing '.c' to --event

      This patch provides infrastructure for passing source files to --event
      directly using:

       # perf record --event bpf-file.c command

      This patch does following works:

       1) Allow passing '.c' file to '--event'. parse_events_load_bpf() is
          expanded to allow caller tell it whether the passed file is source
          file or object.

       2) llvm__compile_bpf() is called to compile the '.c' file, the result
          is saved into memory. Use bpf_object__open_buffer() to load the
          in-memory object.

      Introduces a bpf-script-example.c so we can manually test it:

       # perf record --clang-opt "-DLINUX_VERSION_CODE=0x40200" --event 
./bpf-script-example.c sleep 1

      Note that '--clang-opt' must put before '--event'.

      Futher patches will merge it into a testcase so can be tested 
automatically.

      perf record: Add clang options for compiling BPF scripts

      Although previous patch allows setting BPF compiler related options in
      perfconfig, on some ad-hoc situation it still requires passing options
      through cmdline. This patch introduces 2 options to 'perf record' for
      this propose: --clang-path and --clang-opt.

      perf bpf: Attach eBPF filter to perf event

      This is the final patch which makes basic BPF filter work. After
      applying this patch, users are allowed to use BPF filter like:

       # perf record --event ./hello_world.o ls

      A bpf_fd field is appended to 'struct evsel', and setup during the
      callback function add_bpf_event() for each 'probe_trace_event'.

      PERF_EVENT_IOC_SET_BPF ioctl is used to attach eBPF program to a newly
      created perf event. The file descriptor of the eBPF program is passed to
      perf record using previous patches, and stored into evsel->bpf_fd.

      It is possible that different perf event are created for one kprobe
      events for different CPUs. In this case, when trying to call the ioctl,
      EEXIST will be return. This patch doesn't treat it as an error.

      Committer note:

      The bpf proggie used so far:

        __attribute__((section("fork=_do_fork"), used))
        int fork(void *ctx)
        {
          return 0;
        }

        char _license[] __attribute__((section("license"), used)) = "GPL";
        int _version __attribute__((section("version"), used)) = 0x40300;

      failed to produce any samples, even with forks happening and it being
      running in system wide mode.

      That is because now the filter is being associated, and the code above
      always returns zero, meaning that all forks will be probed but filtered
      away ;-/

      Change it to 'return 1;' instead and after that:

        # trace --no-syscalls --event /tmp/foo.o
           0.000 perf_bpf_probe:fork:(ffffffff8109be30))
           2.333 perf_bpf_probe:fork:(ffffffff8109be30))
           3.725 perf_bpf_probe:fork:(ffffffff8109be30))
           4.550 perf_bpf_probe:fork:(ffffffff8109be30))
        ^C#

      And it works with all tools, including 'perf trace'.

      perf script: Enable printing of branch stack

      This patch improves perf script by enabling printing of the
      branch stack via the 'brstack' and 'brstacksym' arguments to
      the field selection option -F. The option is off by default
      and operates only if the perf.data file has branch stack content.

      The branches are printed in to/from pairs. The most recent branch
      is printed first. The number of branch entries vary based on the
      underlying hardware and filtering used.

      The brstack prints FROM/TO addresses in raw hexadecimal format.
      The brstacksym prints FROM/TO addresses in symbolic form wherever
      possible.

       $ perf script -F ip,brstack
        5d3000 0x401aa0/0x5d2000/M/-/-/-/0 ...

       $ perf script -F ip,brstacksym
        4011e0 noploop+0x0/noploop+0x0/P/-/-/0

      The notation F/T/M/X/A/C describes the attributes of the branch.
      F=from, T=to, M/P=misprediction/prediction, X=TSX, A=TSX abort, C=cycles

      arm64: page-align sections for DEBUG_RODATA

      A kernel built with DEBUG_RO_DATA && !CONFIG_DEBUG_ALIGN_RODATA doesn't
      have .text aligned to a page boundary, though fixup_executable works at
      page-granularity thanks to its use of create_mapping. If .text is not
      page-aligned, the first page it exists in may be marked non-executable,
      leading to failures when an attempt is made to execute code in said
      page.

      This patch upgrades ALIGN_DEBUG_RO and ALIGN_DEBUG_RO_MIN to force page
      alignment for DEBUG_RO_DATA && !CONFIG_DEBUG_ALIGN_RODATA kernels,
      ensuring that all sections with specific RWX permission requirements are
      mapped with the correct permissions.

      arm64/efi: do not assume DRAM base is aligned to 2 MB

      The current arm64 Image relocation code in the UEFI stub assumes that
      the dram_base argument it receives is always a multiple of 2 MB. In
      reality, it is simply the lowest start address of all RAM entries in
      the UEFI memory map, which means it could be any multiple of 4 KB.

      Since the arm64 kernel Image needs to reside TEXT_OFFSET bytes beyond
      a 2 MB aligned base, or it will fail to boot, make sure we round dram_base
      to 2 MB before using it to calculate the relocation address.

      ipv6: protect mtu calculation of wrap-around and infinite loop by 
rounding issues

      Raw sockets with hdrincl enabled can insert ipv6 extension headers
      right into the data stream. In case we need to fragment those packets,
      we reparse the options header to find the place where we can insert
      the fragment header. If the extension headers exceed the link's MTU we
      actually cannot make progress in such a case.

      Instead of ending up in broken arithmetic or rounding towards 0 and
      entering an endless loop in ip6_fragment, just prevent those cases by
      aborting early and signal -EMSGSIZE to user space.

      This is the second version of the patch which doesn't use the
      overflow_usub function, which got reverted for now.

      For the messages from host to target, shadow copy of CE descriptors

      To optimize in download path and to reduce d-cache pressure, removing

      The physical address necessary to unmap DMA ('bufferp') is stored
      in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id
      when handling send completion (htc ep id is stored in sk_buff control
      buffer). So the unused output arguments {bufferp, nbytesp and 
transfer_idp}
      are removed from CE send completion. This change is needed before removing
      the shadow copy of copy engine (CE) descriptors in follow up patch.

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      User visible changes:

        - Enable per-event perf_event_attr.inherit setting by config terms, i.e.
          this becomes possible:

              $ perf record -e cycles/inherit/ -e instructions/no-inherit/

          This affects the default, that can be changed globally using the 
--no-inherit
          option.

          This fine grained control appeared in the eBPF patchkit, but this 
added
          flexibility may end up being useful in other scenarios. (Wang Nan)

        - Setup pager when printing usage and help, we have long lists of 
options,
          better use the pager like we do with normal tooling output, i.e. when 
needed,
          and including any error messages in the paged output. (Namhyung Kim)

        - Search for more options when passing args to -h, e.g.: (Arnaldo 
Carvalho de Melo)

          $ perf report -h interface

           Usage: perf report [<options>]

            --gtk    Use the GTK2 interface
            --stdio  Use the stdio interface
            --tui    Use the TUI interface

        - Fix reading separate debuginfo files based on a build-id, problem
          found on a Debian system. (Dima Kogan)

        - Fix endless loop when splitting kallsyms symbols per section for
          handling kcore files, problem found on a s390x system. (Jiri Olsa)

      Infrastructure changes:

        - Prep work for the 'perf stat record' work that will allow generating
          perf.data files with counting data in addition to the sampling mode
          we have now (Jiri Olsa)

      ath10k: enable adaptive CCA

      European Union has made it mandatory that all devices working in 2.4 GHz
      has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
      beginnig this year. The standard basically speaks about interferences
      in 2.4Ghz band.
      For example, when 802.11 device detects interference, TX must be stopped
      as long as interference is present.

      Adaptive CCA is a feature, when enabled the device learns from the
      environment and configures CCA levels adaptively. This will improve
      detecting interferences and the device can stop trasmissions till the
      interference is present eventually leading to good performances in
      varying interference conditions.

      The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
      QCA988X.

      arm64: Increase the max granular size

      Increase the standard cacheline size to avoid having locks in the same
      cacheline.

      Cavium's ThunderX core implements cache lines of 128 byte size. With
      current granulare size of 64 bytes (L1_CACHE_SHIFT=6) two locks could
      share the same cache line leading a performance degradation.
      Increasing the size fixes that.

      Increasing the size has no negative impact to cache invalidation on
      systems with a smaller cache line. There is an impact on memory usage,
      but that's not too important for arm64 use cases.

      ssb: pick PCMCIA host code support from b43 driver

      ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO.
      Every ssb bus contains cores AKA devices.
      The main idea is to have ssb driver scan/initialize bus and register
      ready-to-use cores. This way ssb drivers can operate on a single core
      mostly ignoring underlaying details.

      For some reason PCMCIA support was split between ssb and b43. We got
      PCMCIA host device probing in b43, then bus scanning in ssb and then
      wireless core probing back in b43. The truth is it's very unlikely we
      will ever see PCMCIA ssb device with no 802.11 core but I still don't
      see any advantage of the current architecture.

      With proposed change we get the same functionality with a simpler
      architecture, less Kconfig symbols, one killed EXPORT and hopefully
      cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb
      specific code in ssb driver.

      This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We
      already use similar solution with b43_pci_bridge.c. I didn't use "b43"
      in name of this new file as in theory any driver can operate on wireless
      core.

      mwifiex: toggle carrier state in start_ap/stop_ap.

      In uap mode the carrier is not enabled until after the first STA joins.
      The carrier triggers the bridge to start its state machine, and if STP
      is enabled, it takes 4 seconds as it transitions from disabled to
      forwarding. During this time the bridge drops all traffic, and the EAPOL
      handshake times out after 3 seconds, preventing stations from joining.

      Follow the logic used in mac80211 and start the carrier in start_ap
      and disable it in stop_ap. This has a nice benefit of allowing the
      first station connection time to be reduced by up to 75% when STP is
      in use.

      wcn36xx: introduce per-channel ring buffer locks

      wcn36xx implements a ring buffer for transmitted frames for each
      (high and low priority) DMA channel.  The ring buffers are lockless:
      new frames are inserted at the head of the queue, while finished
      packets are reaped from the tail.

      Unfortunately, the list manipulations are missing any kind of barriers
      so are susceptible to various races: for example, a TX completion
      handler might read an updated desc->ctrl before the head has actually
      advanced, and then null out the ctl->skb pointer while it is still
      being used in the TX path.

      Simplify things here by adding a spin lock when traversing the ring.
      This change increased stability for me without adding any noticeable
      overhead on my platform (xperia z).

      ath9k: fix phyerror codes

      Some of the ath9k_phyerr enums were wrong from the
      beginning (and even before). Most of the time the
      codes were used for counters to be displayed over
      debugfs, which made this a non-functional issue.

      Some (e.g. ATH9K_PHYERR_FALSE_RADAR_EXT) are used
      for radar detection and require the correct code
      to work as intended.

      This patch includes:
      a) fixes
        ATH9K_PHYERR_FALSE_RADAR_EXT:    24 => 36
        ATH9K_PHYERR_CCK_LENGTH_ILLEGAL: 32 => 28
        ATH9K_PHYERR_CCK_POWER_DROP:     33 => 29
        ATH9K_PHYERR_HT_CRC_ERROR:       34 => 32
        ATH9K_PHYERR_HT_LENGTH_ILLEGAL:  35 => 33
        ATH9K_PHYERR_HT_RATE_ILLEGAL:    36 => 34

      b) extensions
        ATH9K_PHYERR_CCK_BLOCKER = 24
        ATH9K_PHYERR_HT_ZLF      = 35
        ATH9K_PHYERR_GREEN_FIELD = 37

      Aside from the correction and completion made in
      the enum, the patch also extends the display of
      the related counters in the debugfs.

      usb: musb: omap2430: Fix regression caused by driver core change

      Commit ddef08dd00f5 ("Driver core: wakeup the parent device before trying
      probe") started automatically ensuring the parent device is enabled when
      the child gets probed.

      This however caused a regression for MUSB omap2430 interface as the
      runtime PM for the parent device needs the child initialized to access
      the MUSB hardware registers.

      Let's delay the enabling of PM runtime for the parent until the child
      has been properly initialized as suggested in an earlier patch by
      Grygorii Strashko <grygorii.strashko@xxxxxx>.

      In addition to delaying pm_runtime_enable, we now also need to make sure
      the parent is enabled during omap2430_musb_init. We also want to propagate
      an error from omap2430_runtime_resume if struct musb is not initialized.

      Note that we use pm_runtime_put_noidle here for both the child and parent
      to prevent an extra runtime_suspend/resume cycle.

      Let's also add some comments to avoid confusion between the
      two different devices.

      This reverts commit e306dfd06fcb44d21c80acb8e5a88d55f3d1cf63.

      With this patch applied, we were the only architecture making this sort
      of adjustment to the PC calculation in the unwinder. This causes
      problems for ftrace, where the PC values are matched against the
      contents of the stack frames in the callchain and fail to match any
      records after the address adjustment.

      Whilst there has been some effort to change ftrace to workaround this,
      those patches are not yet ready for mainline and, since we're the odd
      architecture in this regard, let's just step in line with other
      architectures (like arch/arm/) for now.

      arm64: kernel: fix tcr_el1.t0sz restore on systems with extended idmap

      Commit dd006da21646 ("arm64: mm: increase VA range of identity map")
      introduced a mechanism to extend the virtual memory map range
      to support arm64 systems with system RAM located at very high offset,
      where the identity mapping used to enable/disable the MMU requires
      additional translation levels to map the physical memory at an equal
      virtual offset.

      The kernel detects at boot time the tcr_el1.t0sz value required by the
      identity mapping and sets-up the tcr_el1.t0sz register field accordingly,
      any time the identity map is required in the kernel (ie when enabling the
      MMU).

      After enabling the MMU, in the cold boot path the kernel resets the
      tcr_el1.t0sz to its default value (ie the actual configuration value for
      the system virtual address space) so that after enabling the MMU the
      memory space translated by ttbr0_el1 is restored as expected.

      Commit dd006da21646 ("arm64: mm: increase VA range of identity map")
      also added code to set-up the tcr_el1.t0sz value when the kernel resumes
      from low-power states with the MMU off through cpu_resume() in order to
      effectively use the identity mapping to enable the MMU but failed to add
      the code required to restore the tcr_el1.t0sz to its default value, when
      the core returns to the kernel with the MMU enabled, so that the kernel
      might end up running with tcr_el1.t0sz value set-up for the identity
      mapping which can be lower than the value required by the actual virtual
      address space, resulting in an erroneous set-up.

      This patchs adds code in the resume path that restores the tcr_el1.t0sz
      default value upon core resume, mirroring this way the cold boot path
      behaviour therefore fixing the issue.

      arm64: compat: fix stxr failure case in SWP emulation

      If the STXR instruction fails in the SWP emulation code, we leave *data
      overwritten with the loaded value, therefore corrupting the data written
      by a subsequent, successful attempt.

      This patch re-jigs the code so that we only write back to *data once we
      know that the update has happened.

      ARM: OMAP1: fix incorrect INT_DMA_LCD

      Commit 685e2d08c54b ("ARM: OMAP1: Change interrupt numbering for
      sparse IRQ") turned on SPARSE_IRQ on OMAP1, but forgot to change
      the number of INT_DMA_LCD. This broke the boot at least on Nokia 770,
      where the device hangs during framebuffer initialization.

      Fix by defining INT_DMA_LCD like the other interrupts.

      perf bpf: Collect perf_evsel in BPF object files

      This patch creates a 'struct perf_evsel' for every probe in a BPF object
      file(s) and fills 'struct evlist' with them. The previously introduced
      dummy event is now removed. After this patch, the following command:

       # perf record --event filter.o ls

      Can trace on each of the probes defined in filter.o.

      The core of this patch is bpf__foreach_tev(), which calls a callback
      function for each 'struct probe_trace_event' event for a bpf program
      with each associated file descriptors. The add_bpf_event() callback
      creates evsels by calling parse_events_add_tracepoint().

      Since bpf-loader.c will not be built if libbpf is turned off, an empty
      bpf__foreach_tev() is defined in bpf-loader.h to avoid build errors.

      Committer notes:

      Before:

        # /tmp/oldperf record --event /tmp/foo.o -a usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.198 MB perf.data ]
        # perf evlist
        /tmp/foo.o
        # perf evlist -v
        /tmp/foo.o: type: 1, size: 112, config: 0x9, { sample_period,
        sample_freq }: 4000, sample_type: IP|TID|TIME|CPU|PERIOD, disabled: 1,
        inherit: 1, mmap: 1, comm: 1, freq: 1, task: 1, sample_id_all: 1,
        exclude_guest: 1, mmap2: 1, comm_exec: 1

      I.e. we create just the PERF_TYPE_SOFTWARE (type: 1),
      PERF_COUNT_SW_DUMMY(config 0x9) event, now, with this patch:

        # perf record --event /tmp/foo.o -a usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.210 MB perf.data ]
        # perf evlist -v
        perf_bpf_probe:fork: type: 2, size: 112, config: 0x6bd, { sample_period,
        sample_freq }: 1, sample_type: IP|TID|TIME|CPU|PERIOD|RAW, disabled: 1,
        inherit: 1, mmap: 1, comm: 1, task: 1, sample_id_all: 1, exclude_guest:
        1, mmap2: 1, comm_exec: 1
        #

      We now have a PERF_TYPE_SOFTWARE (type: 1), but the config states 0x6bd,
      which is how, after setting up the event via the kprobes interface, the
      'perf_bpf_probe:fork' event is accessible via the perf_event_open
      syscall. This is all transient, as soon as the 'perf record' session
      ends, these probes will go away.

      To see how it looks like, lets try doing a neverending session, one that
      expects a control+C to end:

        # perf record --event /tmp/foo.o -a

      So, with that in place, we can use 'perf probe' to see what is in place:

        # perf probe -l
          perf_bpf_probe:fork  (on _do_fork@acme/git/linux/kernel/fork.c)

      We also can use debugfs:

        [root@felicio ~]# cat /sys/kernel/debug/tracing/kprobe_events
        p:perf_bpf_probe/fork _text+638512

      Ok, now lets stop and see if we got some forks:

        [root@felicio linux]# perf record --event /tmp/foo.o -a
        ^C[ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.325 MB perf.data (111 samples) ]

        [root@felicio linux]# perf script
            sshd  1271 [003] 81797.507678: perf_bpf_probe:fork: 
(ffffffff8109be30)
            sshd 18309 [000] 81797.524917: perf_bpf_probe:fork:

            sshd 18309 [001] 81799.381603: perf_bpf_probe:fork:

        <SNIP>

      Sure enough, we have 111 forks :-)

      Callchains seems to work as well:

      perf tools: Load eBPF object into kernel

      This patch utilizes bpf_object__load() provided by libbpf to load all
      objects into kernel.

      Committer notes:

      Testing it:

      When using an incorrect kernel version number, i.e., having this in your
      eBPF proggie:

        int _version __attribute__((section("version"), used)) = 0x40100;

      For a 4.3.0-rc6+ kernel, say, this happens and needs checking at event
      parsing time, to provide a better error report to the user:

        # perf record --event /tmp/foo.o sleep 1
        libbpf: load bpf program failed: Invalid argument
        libbpf: -- BEGIN DUMP LOG ---
        libbpf:

        libbpf: -- END LOG --
        libbpf: failed to load program 'fork=_do_fork'
        libbpf: failed to load object '/tmp/foo.o'
        event syntax error: '/tmp/foo.o'
                             \___ Invalid argument: Are you root and runing a 
CONFIG_BPF_SYSCALL kernel?

        (add -v to see detail)
        Run 'perf list' for a list of valid events

         Usage: perf record [<options>] [<command>]
            or: perf record [<options>] -- <command> [<options>]

            -e, --event <event>   event selector. use 'perf list' to list 
available events

      If we instead make it match, i.e. use 0x40300 on this v4.3.0-rc6+
      kernel, the whole process goes thru:

        # perf record --event /tmp/foo.o -a usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.202 MB perf.data ]
        # perf evlist -v
        /tmp/foo.o: type: 1, size: 112, config: 0x9, { sample_period,

      perf tools: Create probe points for BPF programs

      This patch introduces bpf__{un,}probe() functions to enable callers to
      create kprobe points based on section names a BPF program. It parses the
      section names in the program and creates corresponding 'struct
      perf_probe_event' structures. The parse_perf_probe_command() function is
      used to do the main parsing work. The resuling 'struct perf_probe_event'
      is stored into program private data for further using.

      By utilizing the new probing API, this patch creates probe points during
      event parsing.

      To ensure probe points be removed correctly, register an atexit hook so
      even perf quit through exit() bpf__clear() is still called, so probing
      points are cleared. Note that bpf_clear() should be registered before
      bpf__probe() is called, so failure of bpf__probe() can still trigger
      bpf__clear() to remove probe points which are already probed.

      strerror style error reporting scaffold is created by this patch.
      bpf__strerror_probe() is the first error reporting function in
      bpf-loader.c.

      Committer note:

      Trying it:

      To build a test eBPF object file:

      I am testing using a script I built from the 'perf test -v LLVM' output:

       ---

      First asking to put a probe in a function not present in the kernel
      (misses the initial _):

        $ perf record --event /tmp/foo.o sleep 1
        Probe point 'do_fork' not found.
        event syntax error: '/tmp/foo.o'
                             \___ You need to check probing points in BPF file

        (add -v to see detail)
        Run 'perf list' for a list of valid events

         Usage: perf record [<options>] [<command>]
            or: perf record [<options>] -- <command> [<options>]

            -e, --event <event>   event selector. use 'perf list' to list

        $

       ---

      Now, with "__attribute__((section("fork=_do_fork"), used)):

       $ grep _do_fork /proc/kallsyms
       ffffffff81099ab0 T _do_fork
       $ perf record --event /tmp/foo.o sleep 1
       Failed to open kprobe_events: Permission denied
       event syntax error: '/tmp/foo.o'
                            \___ Permission denied

       ---

      Cool, we need to provide some better hints, "kprobe_events" is too low
      level, one doesn't strictly need to know the precise details of how
      these things are put in place, so something that shows the command
      needed to fix the permissions would be more helpful.

      Lets try as root instead:

        # perf record --event /tmp/foo.o sleep 1

      perf tools: Enable passing bpf object file to --event

      By introducing new rules in tools/perf/util/parse-events.[ly], this
      patch enables 'perf record --event bpf_file.o' to select events by an
      eBPF object file. It calls parse_events_load_bpf() to load that file,
      which uses bpf__prepare_load() and finally calls bpf_object__open() for
      the object files.

      After applying this patch, commands like:

       # perf record --event foo.o sleep

      become possible.

      However, at this point it is unable to link any useful things onto the
      evsel list because the creating of probe points and BPF program
      attaching have not been implemented.  Before real events are possible to
      be extracted, to avoid perf report error because of empty evsel list,
      this patch link a dummy evsel. The dummy event related code will be
      removed when probing and extracting code is ready.

      perf ebpf: Add the libbpf glue

      The 'bpf-loader.[ch]' files are introduced in this patch. Which will be
      the interface between perf and libbpf. bpf__prepare_load() resides in
      bpf-loader.c. Following patches will enrich these two files.

      perf tools: Make perf depend on libbpf

      By adding libbpf into perf's Makefile, this patch enables perf to build
      libbpf if libelf is found and neither NO_LIBELF nor NO_LIBBPF is set.

      The newly introduced code is similar to how libapi and libtraceevent
      are wired into Makefile.perf.

      MANIFEST is also updated for 'make perf-*-src-pkg'.

      Append make_no_libbpf to tools/perf/tests/make.

      The 'bpf' feature check is appended into default FEATURE_TESTS and
      FEATURE_DISPLAY, so perf will check the API version of bpf in
      /path/to/kernel/include/uapi/linux/bpf.h. Which should not fail except
      when we are trying to port this code to an old kernel.

      Error messages are also updated to notify users about the lack of BPF
      support in 'perf record' if libelf is missing or the BPF API check
      failed.

      tools/lib/bpf is added to TAG_FOLDERS to allow us to navigate libbpf
      files when working on perf using tools/perf/tags.

      clocksource/drivers/sh_mtu2: Fix multiple shutdown call issue

      On the r7s72100 Genmai board the MTU2 driver currently triggers a common
      clock framework WARN_ON(enable_count) when disabling the clock due to
      the MTU2 driver after recent callback rework may call 
->set_state_shutdown()
      multiple times. A similar issue was spotted for the TMU driver and fixed 
in:

      perf symbols: Fix endless loop in dso__split_kallsyms_for_kcore

      Currently we split symbols based on the map comparison, but symbols are 
stored
      within dso objects and maps could point into same dso objects (kernel 
maps).

      Hence we could end up changing rbtree we are currently iterating and mess 
it
      up. It's easily reproduced on s390x by running:

        $ perf record -a -- sleep 3
        $ perf buildid-list -i perf.data --with-hits

      The fix is to compare dso objects instead.

      perf tools: Enable pre-event inherit setting by config terms

      This patch allows perf record setting event's attr.inherit bit by
      config terms like:

        # perf record -e cycles/no-inherit/ ...
        # perf record -e cycles/inherit/ ...

      So user can control inherit bit for each event separately.

      In following example, a.out fork()s in main then do some complex
      CPU intensive computations in both of its children.

      Basic result with and without inherit:

        # perf record -e cycles -e instructions ./a.out
        [ perf record: Woken up 9 times to write data ]
        [ perf record: Captured and wrote 2.205 MB perf.data (47920 samples) ]
        # perf report --stdio
        # ...
        # Samples: 23K of event 'cycles'
        # Event count (approx.): 23641752891
        ...
        # Samples: 24K of event 'instructions'
        # Event count (approx.): 30428312415

        # perf record -i -e cycles -e instructions ./a.out
        [ perf record: Woken up 5 times to write data ]
        [ perf record: Captured and wrote 1.111 MB perf.data (24019 samples) ]
        ...
        # Samples: 12K of event 'cycles'
        # Event count (approx.): 11699501775
        ...
        # Samples: 12K of event 'instructions'
        # Event count (approx.): 15058023559

      Cancel inherit for one event when globally enable:

        # perf record -e cycles/no-inherit/ -e instructions ./a.out
        [ perf record: Woken up 7 times to write data ]
        [ perf record: Captured and wrote 1.660 MB perf.data (36004 samples) ]
        ...
        # Samples: 12K of event 'cycles/no-inherit/'
        # Event count (approx.): 11895759282
       ...
        # Samples: 24K of event 'instructions'
        # Event count (approx.): 30668000441

      Enable inherit for one event when globally disable:

        # perf record -i -e cycles/inherit/ -e instructions ./a.out
        [ perf record: Woken up 7 times to write data ]
        [ perf record: Captured and wrote 1.654 MB perf.data (35868 samples) ]
        ...
        # Samples: 23K of event 'cycles/inherit/'
        # Event count (approx.): 23285400229
        ...
        # Samples: 11K of event 'instructions'
        # Event count (approx.): 14969050259

      Committer note:

      One can check if the bit was set, in addition to seeing the result in
      the perf.data file size as above by doing one of:

        # perf record -e cycles -e instructions -a usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.911 MB perf.data (63 samples) ]
        # perf evlist -v
        cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: 
IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, inherit: 1, mmap: 1, 
comm: 1, freq: 1, task: 1, sample_id_all: 1, exclude_guest: 1, mmap2: 1, 
comm_exec: 1
        instructions: size: 112, config: 0x1, { sample_period, sample_freq }: 
4000, sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, 
inherit: 1, freq: 1, sample_id_all: 1, exclude_guest: 1
        #

      So, the inherit bit was set in both, now, if we disable it globally using
      --no-inherit:

        # perf record --no-inherit -e cycles -e instructions -a usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.910 MB perf.data (56 samples) ]
        # perf evlist -v
        cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: 
IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, mmap: 1, comm: 1, 
freq: 1, task: 1, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1
        instructions: size: 112, config: 0x1, { sample_period, sample_freq }: 
4000, sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, 
freq: 1, sample_id_all: 1, exclude_guest: 1

      No inherit bit set, then disabling it and setting just on the cycles 
event:

        # perf record --no-inherit -e cycles/inherit/ -e instructions -a usleep 
1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.909 MB perf.data (48 samples) ]
        # perf evlist -v
        cycles/inherit/: size: 112, { sample_period, sample_freq }: 4000, 
sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, inherit: 
1, mmap: 1, comm: 1, freq: 1, task: 1, sample_id_all: 1, exclude_guest: 1, 
mmap2: 1, comm_exec: 1
        instructions: size: 112, config: 0x1, { sample_period, sample_freq }: 
4000, sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, 
freq: 1, sample_id_all: 1, exclude_guest: 1
        #

      We can see it as well in by using a more verbose level of debug messages 
in
      the tool that sets up the perf_event_attr, 'perf record' in this case:

        [root@zoo ~]# perf record -vv --no-inherit -e cycles/inherit/ -e 
instructions -a usleep 1

      ARC: mm: HIGHMEM: kmap API implementation

      Implement kmap* API for ARC.

      This enables
       - permanent kernel maps (pkmaps): :kmap() API
       - fixmap : kmap_atomic()

      We use a very simple/uniform approach for both (unlike some of the other
      arches). So fixmap doesn't use the customary compile time address stuff.
      The important semantic is sleep'ability (pkmap) vs. not (fixmap) which
      the API guarantees.

      Note that this patch only enables highmem for subsequent PAE40 support
      as there is no real highmem for ARC in pure 32-bit paradigm as explained
      below.

      ARC has 2:2 address split of the 32-bit address space with lower half
      being translated (virtual) while upper half unstranslated
      (0x8000_0000 to 0xFFFF_FFFF). kernel itself is linked at base of
      unstranslated space (i.e. 0x8000_0000 onwards), which is mapped to say
      DDR 0x0 by external Bus Glue logic (outside the core). So kernel can
      potentially access 1.75G worth of memory directly w/o need for highmem.
      (the top 256M is taken by uncached peripheral space from 0xF000_0000 to
      0xFFFF_FFFF)

      In PAE40, hardware can address memory beyond 4G (0x1_0000_0000) while
      the logical/virtual addresses remain 32-bits. Thus highmem is required
      for kernel proper to be able to access these pages for it's own purposes
      (user space is agnostic to this anyways).

      perf symbols: we can now read separate debug-info files based on a build 
ID

      Recent GDB (at least on a vanilla Debian box) looks for debug information 
in

        /usr/lib/debug/.build-id/nn/nnnnnnn

      where nn/nnnnnn is the build-id of the stripped ELF binary. This is
      documented here:

        https://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html

      This was not working in perf because we didn't read the build id until
      AFTER we searched for the separate debug information file. This patch
      reads the build ID and THEN does the search.

      fs/writeback, rcu: Don't use list_entry_rcu() for pointer offsetting in 
bdi_split_work_to_wbs()

      bdi_split_work_to_wbs() uses list_for_each_entry_rcu_continue()
      to walk @bdi->wb_list.  To set up the initial iteration
      condition, it uses list_entry_rcu() to calculate the entry
      pointer corresponding to the list head; however, this isn't an
      actual RCU dereference and using list_entry_rcu() for it ended
      up breaking a proposed list_entry_rcu() change because it was
      feeding an non-lvalue pointer into the macro.

      Don't use the RCU variant for simple pointer offsetting.  Use
      list_entry() instead.

      efi: Fix warning of int-to-pointer-cast on x86 32-bit builds

      Commit:

        0f96a99dab36 ("efi: Add "efi_fake_mem" boot option")

      introduced the following warning message:

        drivers/firmware/efi/fake_mem.c:186:20: warning: cast to pointer from 
integer of different size [-Wint-to-pointer-cast]

      new_memmap_phy was defined as a u64 value and cast to void*,
      causing a int-to-pointer-cast warning on x86 32-bit builds.
      However, since the void* type is inappropriate for a physical
      address, the definition of struct efi_memory_map::phys_map has
      been changed to phys_addr_t in the previous patch, and so the
      cast can be dropped entirely.

      This patch also changes the type of the "new_memmap_phy"
      variable from "u64" to "phys_addr_t" to align with the types of
      memblock_alloc() and struct efi_memory_map::phys_map.

      efi: Use correct type for struct efi_memory_map::phys_map

      We have been getting away with using a void* for the physical
      address of the UEFI memory map, since, even on 32-bit platforms
      with 64-bit physical addresses, no truncation takes place if the
      memory map has been allocated by the firmware (which only uses
      1:1 virtually addressable memory), which is usually the case.

      However, commit:

        0f96a99dab36 ("efi: Add "efi_fake_mem" boot option")

      adds code that clones and modifies the UEFI memory map, and the
      clone may live above 4 GB on 32-bit platforms.

      This means our use of void* for struct efi_memory_map::phys_map has
      graduated from 'incorrect but working' to 'incorrect and
      broken', and we need to fix it.

      So redefine struct efi_memory_map::phys_map as phys_addr_t, and
      get rid of a bunch of casts that are now unneeded.

      ARC: smp: Introduce smp hook @init_early_smp for Master core

      This adds a platform agnostic early SMP init hook which is called on
      Master core before calling setup_processor()

        setup_arch()
           smp_init_cpus()
               smp_ops.init_early_smp()
           ...
           setup_processor()

      How this helps:
       - Used for one time init of certain SMP centric IP blocks, before
         calling setup_processor() which probes various bits of core,
         possibly including this block

       - Currently platforms need to call this IP block init from their
         init routines, which doesn't make sense as this is specific to ARC
         core and not platform and otherwise requires copy/paste in all
         (and hence a possible point of failure)

      e.g. MCIP init is called from 2 platforms currently (axs10x and sim)
      which will go away once we have this.

      This change only adds the hooks but they are empty for now. Next commit
      will populate them and remove the explicit init calls from platforms.

      ARC: smp: irqchip: handle IPI as percpu irq like timer

      The reason this was not done so far was lack of genuine IPI_IRQ for
      ARC700, as we don't have a SMP version of core yet (which might change
      soon thx to EZChip). Nevertheles to increase the build coverage, we
      need to allow CONFIG_SMP for ARC700 and still be able to run it on a
      UP platform (nsim or AXS101) with a UP Device Tree (SMP-on-UP)

      The build itself requires some define for IPI_IRQ and even a dummy
      value is fine since that code won't run anyways.

      mlx4_eqe as the base size and not caps.eqe_size which could be bigger.

      If caps.eqe_size is bigger than the struct mlx4_eqe then we corrupt
      data in the master context.

      When using a 64 byte stride, the memcpy copied over 63 bytes to the
      slave_eq structure.  This resulted in copying over the entire eqe of
      interest, including its ownership bit -- and also 31 bytes of garbage
      into the next WQE in the slave EQ -- which did NOT include the ownership
      bit (and therefore had no impact).

      However, once the stride is increased to 128, we are overwriting the
      ownership bits of *three* eqes in the slave_eq struct.  This results
      in an incorrect ownership bit for those eqes, which causes the eq to
      seem to be full. The issue therefore surfaced only once 128-byte EQEs
      started being used in SRIOV and (overarchitectures that have 128/256
      byte cache-lines such as PPC) - e.g after commit 77507aa249ae
      "net/mlx4_core: Enable CQE/EQE stride support".

      net/mlx4_en: Explicitly set no vlan tags in WQE ctrl segment when no vlan 
is present

      We do not set the ins_vlan field to zero when no vlan id is present in 
the packet.

      Since WQEs in the TX ring are not zeroed out between uses, this oversight
      could result in having vlan flags present in the WQE ctrl segment when no

      seccomp, ptrace: add support for dumping seccomp filters

      This patch adds support for dumping a process' (classic BPF) seccomp
      filters via ptrace.

      PTRACE_SECCOMP_GET_FILTER allows the tracer to dump the user's classic BPF
      seccomp filters. addr should be an integer which represents the ith 
seccomp
      filter (0 is the most recently installed filter). data should be a struct
      sock_filter * with enough room for the ith filter, or NULL, in which case
      the filter is not saved. The return value for this command is the number 
of
      BPF instructions the program represents, or negative in the case of 
errors.
      Command specific errors are ENOENT: which indicates that there is no ith
      filter in this seccomp tree, and EMEDIUMTYPE, which indicates that the ith
      filter was not installed as a classic BPF filter.

      A caveat with this approach is that there is no way to get explicitly at
      the heirarchy of seccomp filters, and users need to memcmp() filters to
      decide which are inherited. This means that a task which installs two of
      the same filter can potentially confuse users of this interface.

      v2: * make save_orig const
          * check that the orig_prog exists (not necessary right now, but when
             grows eBPF support it will be)
          * s/n/filter_off and make it an unsigned long to match ptrace
          * count "down" the tree instead of "up" when passing a filter offset

      v3: * don't take the current task's lock for inspecting its seccomp mode
          * use a 0x42** constant for the ptrace command value

      v4: * don't copy to userspace while holding spinlocks

      v5: * add another condition to WARN_ON

      v6: * rebase on net-next

      mpls: reduce memory usage of routes

      Nexthops for MPLS routes have a via address field sized for the
      largest via address that is expected, which is 32 bytes. This means
      that in the most common case of having ipv4 via addresses, 28 bytes of
      memory more than required are used per nexthop. In the other common
      case of an ipv6 nexthop then 16 bytes more than required are
      used. With large numbers of MPLS routes this extra memory usage could
      start to become significant.

      To avoid allocating memory for a maximum length via address when not
      all of it is required and to allow for ease of iterating over
      nexthops, then the via addresses are changed to be stored in the same
      memory block as the route and nexthops, but in an array after the end
      of the array of nexthops. New accessors are provided to retrieve a
      pointer to the via address.

      To allow for O(1) access without having to store a pointer or offset
      per nh, the via address for each nexthop is sized according to the
      maximum via address for any nexthop in the route, which is stored in a
      new route field, rt_max_alen, but this is in an existing hole in
      struct mpls_route so it doesn't increase the size of the
      structure. Each via address is ensured to be aligned to VIA_ALEN_ALIGN
      to account for architectures that don't allow unaligned accesses.

      amd-xgbe: Fix race between access of desc and desc index

      During Tx cleanup it's still possible for the descriptor data to be
      read ahead of the descriptor index. A memory barrier is required between
      the read of the descriptor index and the start of the Tx cleanup loop.
      This allows a change to a lighter-weight barrier in the Tx transmit
      routine just before updating the current descriptor index.

      Since the memory barrier does result in extra overhead on arm64, keep
      the previous change to not chase the current descriptor value. This
      prevents the execution of the barrier for each loop performed.

      sock: don't enable netstamp for af_unix sockets

      netstamp_needed is toggled for all socket families if they request
      timestamping. But some protocols don't need the lower-layer timestamping
      code at all. This patch starts disabling it for af-unix.

      E.g. systemd enables timestamping during boot-up on the journald af-unix
      sockets, thus causing the system to globally enable timestamping in the
      lower networking stack. Still, it is very probable that timestamping
      gets activated, by e.g. dhclient or various NTP implementations.

      ====================
      Add new drivers: qed & qede

      This series implements the driver set for Qlogic's new QL4xxx series.
      These are 10/20/25/40/50/100 Gig capable converged nics, supporting
      ethernet (obviously), iscsi, fcoe, roce and iwarp protocols.

      The overall driver design includes a common module ('qed') and protocol
      specific dependent modules for ethernet ('qede'), fcoe ('qedf'),
      iscsi ('qedi') and roce ('qedr').
      The common module contains all of the common logic, e.g. initialization,
      cleanup, infrastructure for interrupt handling, link management, slowpath
      etc. as well as protocol agnostic features, and supplying an abstraction
      layer for other modules.
      The protocol specific modules can be compiled and operated independently
      of each other, with the exception of the rdma modules which are dependent
      on the ethernet module, in accordance with the kernel rdma stack design.

      This series only adds the core and ethernet modules, with basic L2
      capabilities. Future series will add the rest of the modules and enhance
      the L2 functionality.

      Ths patch series is constructed of the following patches:
      qed:  Add module with basic common support
      qed:  Add basic L2 interface
      qede: Add basic Network driver
      qed:  Add slowpath L2 support
      qede: Add basic network device support
      qede: Add classification configuration
      qed:  Add link support
      qede: Add support for link
      qed:  Add statistics support
      qede: Add basic ethtool support

      Changes from previos version:
      -----------------------------

      From Version 7:
        - Various small fixes according to Dave's suggestions; Largest change
          [code-wise] - don't use tabs for indenting function arguments.

      From Version 6:
        - Reduced the number of arguments for functions with exceptionally
          high number of parameters.

      From Version 5:
        - Style change and fixes [mostly in 1, 4 and 7].
          Thanks go to Francois Romieu, a mere mortal. ;-)

      From Version 4:
        - Drop dependency for x86_64.

      From Version 3:
        - Limit support of initial submission to x86_64.
        - Fix endian problems appearing via sparse [although no BE support yet].
        - Fix small issues suggested by the kbuild test robot.

      From Version 2:
        - Removed U64_{HI,LO}; Using {upper,lower}_32_bits instead.
        - Use regular napi weight definition.
        - [We still use the __le variants for variables, since we didn't get
           a reply regarding the change into non-user API types].

      From Version 1:
        - Removed private license file; Instead revised comments at source 
headers.

      qede: Add basic ethtool support

      This adds basic ethtool operations to the qed driver, allowing support in:
       - Statistics gathering [ethtool -S]
       - Setting of debug level [ethtool -s <interface> msglvl]
       - Getting basic information [ethtool, ethtool -i]

      In addition it adds the ability to change the MTU.

      qede: Add support for link

      This adds basic link functionality to qede - driver still doesn't provide
      users with an API to change any link property, but it does request qed to
      initialize the link using default configuration, and registers a callback
      that allows it to get link notifications.

      This patch adds the ability of the driver to set the carrier as active and
      to enable traffic as a result of async. link notifications.
      Following this patch, driver should be capable of running traffic.

      qed: Add link support

      Physical link is handled by the management Firmware.
      This patch lays the infrastructure for attention handling in the driver,
      as link change notifications arrive via async. attentions,
      as well the handling of such notifications.

      This patch also extends the API with the protocol drivers by adding
      registered callbacks which the protocol driver passes to qed in order
      to be notified of async. events originating from the FW/HW.

      The Qlogic Everest Driver for Ethernet is the Ethernet specific module for
      QL4xxx ethernet products by Qlogic.

      This patch adds a very minimal PCI driver, one that doesn't yet register
      a network device, but one that does interact with qed and does a basic

      qed: Add basic L2 interface

      This patch adds a public API for a network driver to work on top of QED.
      The interface itself is very minimal - it's mostly infrastructure, as the
      only content it has after this patch is a query for HW-based information
      required for the creation of a network interface [I.e., no actual
      protocol-specific configurations are supported].

      qed: Add module with basic common support

      The Qlogic Everest Driver is the backend module for the QL4xxx ethernet
      products by Qlogic.

      This module serves two main purposes:
       1. It's responsible to contain all the common code that will be shared
          between the various drivers that would be used with said line of
          products. Flows such as chip initialization and de-initialization
          fall under this category.

       2. It would abstract the protocol-specific HW & FW components, allowing
          the protocol drivers to have a clean APIs which is detached in its
          slowpath configuration from the actual HSI.

      This adds a very basic module without any protocol-specific bits.
      I.e., this adds a basic implementation that almost entirely falls under
      the first category.

      openvswitch: Fix skb leak using IPv6 defrag

      nf_ct_frag6_gather() makes a clone of each skb passed to it, and if the
      reassembly is successful, expects the caller to free all of the original
      skbs using nf_ct_frag6_consume_orig(). This call was previously missing,
      meaning that the original fragments were never freed (with the exception
      of the last fragment to arrive).

      Fix this by ensuring that all original fragments except for the last
      fragment are freed via nf_ct_frag6_consume_orig(). The last fragment
      will be morphed into the head, so it must not be freed yet. Furthermore,
      retain the ->next pointer for the head after skb_morph().

      openvswitch: Fix double-free on ip_defrag() errors

      If ip_defrag() returns an error other than -EINPROGRESS, then the skb is
      freed. When handle_fragments() passes this back up to
      do_execute_actions(), it will be freed again. Prevent this double free
      by never freeing the skb in do_execute_actions() for errors returned by
      ovs_ct_execute. Always free it in ovs_ct_execute() error paths instead.

      fib_trie: leaf_walk_rcu should not compute key if key is less than pn->key

      We were computing the child index in cases where the key value we were
      looking for was actually less than the base key of the tnode.  As a result
      we were getting incorrect index values that would cause us to skip over
      some children.

      To fix this I have added a test that will force us to use child index 0 if
      the key we are looking for is less than the key of the current tnode.

      block: re-add discard_granularity and alignment checks

      In commit b49a087("block: remove split code in
      blkdev_issue_{discard,write_same}"), discard_granularity and alignment
      checks were removed. Ideally, with bio late splitting, the upper layers
      shouldn't need to depend on device's limits.

      Christoph reported a discard regression on the HGST Ultrastar SN100 NVMe
      device when mkfs.xfs. We have not found the root cause yet.

      This patch re-adds discard_granularity and alignment checks by reverting
      the related changes in commit b49a087. The good thing is now we can
      remove the 2G discard size cap and just use UINT_MAX to avoid bi_size
      overflow.

      not update the interrupt status register (GPI_IS) even if the pin is

      does not trigger an interrupt.

      Allow using such pins as GPIOs, only prevent their usage as interrupts.

      On Intel Broxton the GPIO hardware consists of several chips that all 
share
      the parent interrupt. It is not possible to handle this by setting chained
      handler for each chip (as they will overwrite each other).

      To overcome this we need to request the interrupt using devm_request_irq()

      gpio: generic: Revert to old error handling in bgpio_map

      Returning an error instead of NULL in bgpio_map if
      platform_get_resource_byname does not find a resource was introduced with
      commit cf3f2a2c8bae ("gpio: generic: improve error handling in 
bgpio_map").
      This results in several qemu runtime failures with default and non-default
      configurations, if attempts are made to boot from mmcblk0. Examples for
      failures with multi_v7_defconfig are

      Machine: vexpress-a9      dtb: vexpress-v2p-ca9
      Machine: vexpress-a15     dtb: vexpress-v2p-ca15-tc1

      Crash:

      VFS: Cannot open root device "mmcblk0" or unknown-block(0,0): error -6
      Please append a correct "root=" boot option; here are the available 
partitions:
      Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(0,0)

      Looking into the code, always returning an error if bgpio_map fails
      does not appear to make much sense, since the code in bgpio_setup_io
      specifically supports some of the resources to be NULL.

      drivers/pinctrl: Add the concept of an "init" state

      For pinctrl the "default" state is applied to pins before the driver's
      probe function is called.  This is normally a sensible thing to do,
      but in some cases can cause problems.  That's because the pins will
      change state before the driver is given a chance to program how those
      pins should behave.

      As an example you might have a regulator that is controlled by a PWM
      (output high = high voltage, output low = low voltage).  The firmware
      might leave this pin as driven high.  If we allow the driver core to
      reconfigure this pin as a PWM pin before the PWM's probe function runs
      then you might end up running at too low of a voltage while we probe.

      Let's introudce a new "init" state.  If this is defined we'll set
      pinctrl to this state before probe and then "default" after probe
      (unless the driver explicitly changed states already).

      An alternative idea that was thought of was to use the pre-existing
      "sleep" or "idle" states and add a boolean property that we should
      start in that mode.  This was not done because the "init" state is
      needed for correctness and those other states are only present (and
      only transitioned in to and out of) when (optional) power management
      is enabled.

      Changes in v3:
      - Moved declarations to pinctrl/devinfo.h
      - Fixed author/SoB

      Changes in v2:
      - Added comment to pinctrl_init_done() as per Linus W.

      mmc: pwrseq: Use highest priority for eMMC restart handler

      The pwrseq_emmc driver does a eMMC card reset before a system reboot to
      allow broken or limited ROM boot-loaders (that don't have an eMMC reset
      logic) to be able to read the second stage from the eMMC.

      But this has to be called before a system reboot handler and while most
      of them use the priority 128, there are other restart handlers (such as
      the syscon-reboot one) that use a higher priority. So, use the highest
      priority to make sure that the eMMC hw is reset before a system reboot.

      pinctrl: uniphier: set input-enable before pin-muxing

      While IECTRL is disabled, input signals are pulled-down internally.
      If pin-muxing is set up first, glitch signals (Low to High transition)
      might be input to hardware blocks.

      Bad case scenario:
      [1] The hardware block is already running before pinctrl is handled.
         (the reset is de-asserted by default or by a firmware, for example)
      [2] The pin-muxing is set up.  The input signals to hardware block
          are pulled-down by the chip-internal biasing.
      [3] The pins are input-enabled.  The signals from the board reach the
          hardware block.

      Actually, one invalid character is input to the UART blocks for such
      SoCs as PH1-LD4, PH1-sLD8, where UART devices start to run at the
      power on reset.

      To avoid such problems, pins should be input-enabled before muxing.

      bluetooth: 6lowpan: fix NOHZ: local_softirq_pending

      Jukka reported about the following warning:

      "NOHZ: local_softirq_pending 08"

      I remember this warning and we had a similar issue when using workqueues
      and calling netif_rx. See commit 5ff3fec ("mac802154: fix NOHZ
      local_softirq_pending 08 warning").

      This warning occurs when calling "netif_rx" inside the wrong context
      (non softirq context). The net core api offers "netif_rx_ni" to call
      netif_rx inside the correct softirq context.

      Remove all the casts to and from the machine check interruption code.
      This patch changes struct mci to a union, which contains an anonymous
      structure with the already known bits and in addition an unsigned
      long field, which contains the raw machine check interruption code.

      This allows to simply assign and decoce the interruption code value
      without the need for all those casts we had all the time.

      s390/nmi: remove pointless error strings

      s390_handle_damage() has character string parameter which was used as
      a pointer to verbose error message. The hope was (a lot of years ago)
      when analyzing dumps that register R2 would still contain the pointer
      and therefore it would be rather easy to tell what went wrong.

      However gcc optimizes the strings away since a long time. And even if
      it wouldn't it is necessary to have a close look at the machine check
      interruption code to tell what's wrong.

      So remove the pointless error strings.

      s390: don't store registers on disabled wait anymore

      The current disabled wait code stores register contents into their
      save areas, however it is (at least) missing the new vector registers.

      Given the fact that the whole exercise seems to be rather pointless
      simply don't save any registers anymore.

      In a "live" system it is always possible to inspect register contents,
      and in case of a dump the register contents will be stored by the
      dump mechanism.

      net: netcp: add missing of_node_put

      - dynamically check that event is local and !pmu->count
      Otherwise buggy bpf program can cause kernel splat.

      - FACTORY_MODE: Allow to set the driver into a mode where no
        secure element are activated. It does not consider any
        NFC_ATTR_VENDOR_DATA.
      - HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes
        command. It does not consider any NFC_ATTR_VENDOR_DATA.
      - HCI_DM_PUT_DATA: Allow to configure specific CLF registry as
        for example RF trimmings or low level drivers configurations
        (I2C, SPI, SWP).
      - HCI_DM_UPDATE_AID: Allow to configure an AID routing into the
        CLF routing table following RF technology, CLF mode or protocol.
      - HCI_DM_GET_INFO: Allow to retrieve CLF information.
      - HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as
        low level drivers configurations or RF trimmings.
      - HCI_DM_LOAD: Allow to load a firmware into the CLF. A complete
        packet can be more than 8KB.
      - HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF
        configuration changes without CLF power off.
      - HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example
        the white list).
      - HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF
        technology. When using this command to anti-collision is done.
      - HCI_LOOPBACK: Allow to echo a command and test the Dh to CLF
        connectivity.

      NFC: netlink: Add mode parameter to deactivate_target functions

      In order to manage in a better way the nci poll mode state machine,
      add mode parameter to deactivate_target functions.
      This way we can manage different target state.
      mode parameter make sense only in nci core.

      NFC: st-nci: Add ese-present/uicc-present dts properties

      In order to align with st21nfca, dts configuration properties
      ese_present and uicc_present are made available in st-nci driver.

      So far, in early development firmware, because
      nci_nfcee_mode_set(DISABLE) was not supported we had to try to
      enable it during the secure element discovery phase.

      After several trials on commercial and qualified firmware it appears
      that nci_nfcee_mode_set(ENABLE) and nci_nfcee_mode_set(DISABLE) are
      properly supported.

      Such feature also help us to eventually save some time (~5ms) when
      only one secure element is connected.

      NFC: st-nci: Add support for proprietary commands

      Add support for proprietary commands useful mainly for
      factory testings. Here is a list:

      - FACTORY_MODE: Allow to set the driver into a mode where
        no secure element are activated. It does not consider any
        NFC_ATTR_VENDOR_DATA.
      - HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes
        command. It does not consider any NFC_ATTR_VENDOR_DATA.
      - HCI_DM_PUT_DATA: Allow to configure specific CLF registry
        like for example RF trimmings or low level drivers
        configurations (I2C, SPI, SWP).
      - HCI_DM_UPDATE_AID: Allow to configure an AID routing into the
        CLF routing table following RF technology, CLF mode or protocol.
      - HCI_DM_GET_INFO: Allow to retrieve CLF information.
      - HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as
        low level drivers configurations or RF trimmings.
      - HCI_DM_DIRECT_LOAD: Allow to load a firmware into the CLF.
        A complete packet can be more than 8KB.
      - HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF
        configuration changes without CLF power off.
      - HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example
        the white list).
      - HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF
        technology. When using this command to anti-collision is done.
      - HCI_LOOPBACK: Allow to echo a command and test the Dh to CLF
        connectivity.
      - HCI_DM_VDC_MEASUREMENT_VALUE: Allow to measure the field applied
        on the CLF antenna. A value between 0 and 0x0f is returned. 0 is
        maximum.
      - HCI_DM_FWUPD_START: Allow to put CLF into firmware update mode.
        It is a specific CLF command as there is no GPIO for this.
      - HCI_DM_FWUPD_END:  Allow to complete firmware update.
      - HCI_DM_VDC_VALUE_COMPARISON: Allow to compare the field applied
        on the CLF antenna to a reference value.
      - MANUFACTURER_SPECIFIC: Allow to retrieve manufacturer specific data
        received during a NCI_CORE_INIT_CMD.

      scsi_dh: fix use-after-free when removing scsi device

      The commit 1bab0de0274f ("dm-mpath, scsi_dh: don't let dm detach device
      handlers") removed reference counting of attached scsi device handler.
      As a result, handler data is freed immediately via scsi_dh->detach()
      in the context of scsi_remove_device() where activation request can be
      still in flight.

      This patch moves scsi_dh_handler_detach() to sdev releasing function,
      scsi_device_dev_release_usercontext(), at that point the device
      is already in quiesced state.

      net: dsa: bcm_sf2: Unhardcode port numbers

      While the current driver mostly supports BCM7445 which has a hardcoded
      location for its MoCA port on port 7 and port 0 for its internal PHY,
      this is not necessarily true for all other chips out there such as
      BCM3390 for instance.

      Walk the list of ports from Device Tree, get their port number ("reg"
      property), and then parse the "phy-mode" property and initialize two
      internal variables: moca_port and a bitmask of internal PHYs. Since we
      use interrupts for the MoCA port, we introduce two helper functions to
      enable/disable interrupts and do this at the appropriate bank (INTRL2_0
      or INTRL2_1).

      Input: alps - only the Dell Latitude D420/430/620/630 have separate stick 
button bits

      commit 92bac83dd79e ("Input: alps - non interleaved V2 dualpoint has
      separate stick button bits") assumes that all alps v2 non-interleaved
      dual point setups have the separate stick button bits.

      Later we limited this to Dell laptops only because of reports that this
      broke things on non Dell laptops. Now it turns out that this breaks things
      on the Dell Latitude D600 too. So it seems that only the Dell Latitude
      D420/430/620/630, which all share the same touchpad / stick combo,
      have these separate bits.

      This patch limits the checking of the separate bits to only these models
      fixing regressions with other models.

      x86/ioapic: Prevent NULL pointer dereference in setup_ioapic_dest()

      Commit 4857c91f0d19 changed the way how irq affinity is setup in
      setup_ioapic_dest() from using the core helper function to
      unconditionally calling the irq_set_affinity() callback of the
      underlying irq chip.

      That results in a NULL pointer dereference for the rare case where the
      underlying irq chip is lapic_chip which has no irq_set_affinity()
      callback. lapic_chip is occasionally used for the timer interrupt (irq
      0).

      The fix is simple: Check the availability of the callback instead of
      calling it unconditionally.

        Two fixes for bugs that are in both raid1 and raid10.  Both related to
        bad-block-lists and at least one needs to be back ported to 3.1.

        Also a revision for the "new" layout in raid10.  This "new" code
        (which aims to improve robustness) actually reduces robustness in some
        cases.  It probably isn't in use at all as not public user-space code
        makes use of these new layouts.  However just in case someone has
        their own code, it would be good to get the WARNing out for them
        sooner"

      * tag 'md/4.3-rc6-fixes' of git://neil.brown.name/md:
        md/raid10: fix the 'new' raid10 layout to work correctly.
        md/raid10: don't clear bitmap bit when bad-block-list write fails.

      memremap: fix highmem support

      Currently memremap checks if the range is "System RAM" and returns the
      kernel linear address.  This is broken for highmem platforms where a
      range may be "System RAM", but is not part of the kernel linear mapping.
      Fallback to ioremap_cache() in these cases, to let the arch code attempt
      to handle it.

      Note that ARM ioremap will WARN when attempting to remap ram, and in
      that case the caller needs to be fixed.  For this reason, existing
      ioremap_cache() usages for ARM are already trained to avoid attempts to
      remap ram.

      The impact of this bug is low for now since the pmem driver is the only
      user of memremap(), but this is important to fix before more conversions
      to memremap arrive in 4.4.

      perf tools: Setup pager when printing usage and help

      It's annoying to see error or help message when command has many options
      like in perf record, report or top.  So setup pager when print parser
      error or help message - it should be OK since no UI is enabled at the
      parsing time.  The usage_with_options() already disables it by calling
      exit_browser() anyway.

      mmc: dw_mmc-rockchip: MMC tuning with the clock phase framework

      This algorithm will try 1 degree increments, since there's no way to tell
      what resolution the underlying phase code uses. As an added bonus, doing
      many tunings yields better results since some tests are run more than once
      (ex: if the underlying driver uses 45 degree increments, the tuning code
      will try the same angle more than once).

      It will then construct a list of good phase ranges (even ranges that cross
      360/0), will pick the biggest range then it will set the sample_clk to the
      middle of that range.

      We do not touch ciu_drive (and by extension define default-drive-phase).
      Drive phase is mostly used to define minimum hold times, while one could
      write some code to determine what phase meets the minimum hold time (ex 10
      degrees) this will not work with the current clock phase framework (which
      floors angles, so we'll get 0 deg, and there's no way to know what
      resolution the floors happen at). We assume that the default drive angles
      set by the hardware are good enough.

      If a device has device specific code (like exynos) then that will still
      take precedence, otherwise this new code will execute. If the device wants
      to tune, but has no sample_clk defined we'll return EIO with an error
      message.

      mmc: dw_mmc-rockchip: dt-binding: Add tuning related things

      Add ciu_drive, ciu_sample clocks and default-sample-phase. This will later
      be used by tuning code.

      We do not touch ciu_drive (and by extension define default-drive-phase).
      Drive phase is mostly used to define minimum hold times, while one could
      write some code to determine what phase meets the minimum hold time
      (ex 10 degrees) this will not work with the current clock phase framework
      (which floors angles, so we'll get 0 deg, and there's no way to know what
      resolution the floors happen at). We assume that the default drive angles
      set by the hardware are good enough.

      mmc: dw_mmc: Use mmc_regulator_set_vqmmc in start_signal_voltage_switch

      We've introduced a new helper in the MMC core:
      mmc_regulator_set_vqmmc().  Let's use this in dw_mmc.  Using this new
      helper has some advantages:

      1. We get the mmc_regulator_set_vqmmc() behavior of trying to match
         VQMMC and VMMC when the signal voltage is 3.3V.  This ensures max
         compatibility.

      2. We get rid of a few more warnings when probing unsupported
         voltages.

      3. We get rid of some non-dw_mmc specific code in dw_mmc.

      mmc: core: Add mmc_regulator_set_vqmmc()

      This adds logic to the MMC core to set VQMMC.  This is expected to be
      called by MMC drivers like dw_mmc as part of (or instead of) their
      start_signal_voltage_switch() callback.

      A few notes:

      * When setting the signal voltage to 3.3V we do our best to make VQMMC
        and VMMC match.  It's been reported that this makes some old cards
        happy since they were tested back in the day before UHS when VQMMC
        and VMMC were provided by the same regulator.  A nice side effect of
        this is that we don't end up on the hairy edge of VQMMC (2.7V),
        which some EEs claim is a little too close to the minimum for
        comfort.
        This is done in two steps. At first we try to find a VQMMC within
        a 0.3V tolerance of VMMC and if this is not supported by the
        supplying regulator we try to find a suitable voltage within the
        whole 2.7V-3.6V area of the spec.

      * The two step approach is currently necessary, as the used
        regulator_set_voltage_triplet(min, target, max) uses a simple
        implementation that just tries two basic steps:
        regulator_set_voltage(target, max);
        regulator_set_voltage(min, target);
        So with only one step with 2.7-3.6V borders, if a suitable voltage
        is a bit below VMMC, we would directly get the lowest 2.7V
        which some boards (like Rockchips) don't like at all.

      * When setting the signal voltage to 1.8V or 1.2V we aim for that
        specific voltage instead of picking the lowest one in the range.

      * We very purposely don't print errors in mmc_regulator_set_vqmmc().
        There are cases where the MMC core will try several different
        voltages and we don't want to pollute the logs.

      mmc: core: Remove MMC_CLKGATE

      MMC_CLKGATE was once invented to save power by gating the bus clock at
      request inactivity. At that time it served its purpose. The modern way to
      deal with power saving for these scenarios, is by using runtime PM.

      Nowadays, several host drivers have deployed runtime PM, but for those
      that haven't and which still cares power saving at request inactivity,
      it's certainly time to deploy runtime PM as it has been around for several
      years now.

      To simplify code to mmc core and thus decrease maintenance efforts, this
      patch removes all code related to MMC_CLKGATE.

      clk: rockchip: Allow more precision for some mmc clock phases

      Because of the inexact nature of the extra MMC delay elements (it's
      not possible to keep the phase monotonic and to also make phases (mod
      90) > 70), we previously only allowed phases (mod 90) of 22.5, 45,
      and 67.5.

      But it's not the end of the world if the MMC clock phase goes
      non-monotonic.  At most we'll be 25 degrees off.  It's way better to
      test more phases to look for bad ones than to be 25 degrees off, because
      in the case of MMC really the point is to find bad phases and get as far
      asway from the as possible.  If we get to test extra phases by going
      slightly non-monotonic then that might be fine.  Worst case we would
      end up at a phases that's slight differnt than the one we wanted, but
      at least we'd still be quite far away from the a bad phase.

      mmc: block: Add new ioctl to send multi commands

      Certain eMMC devices allow vendor specific device information to be read
      via a sequence of vendor commands. These vendor commands must be issued
      in sequence and an atomic fashion. One way to support this would be to
      add an ioctl function for sending a sequence of commands to the device
      atomically as proposed here. These multi commands are simple array of
      the existing mmc_ioc_cmd structure.

      The structure passed via the ioctl uses a __u64 type to specify the number
      of commands (so that the structure is aligned on a 64-bit boundary) and a
      zero length array as a header for list of commands to be issued. The
      maximum number of commands that can be sent is determined by
      MMC_IOC_MAX_CMDS (which defaults to 255 and should be more than
      sufficient).

      mmc: sdhci: call sdhci_init() before request irq

      sdhci_init() will clear all irqs and set the needed irqs. So
      logically sdhci_init() should be called before request irq.

      If not, some irqs may be triggled and handled wrongly. Take
      the following into consideration, after request irq, if
      SDIO card interrupt enabled, a sd card in the sd slot will
      trigger a mass of interrupt(SDHCI_INT_CARD_INT), because at
      this time, the vmmc-regulator still not restore, no voltage
      supply for the sd card, so the pin of data0~data3 change and
      keep low, interrupt(SDHCI_INT_CARD_INT) will rise up ceaselessly.
      Due to we already reguest irq, system will be busy in handling
      this endless irq, can't response to other event.

      So we should call sdhci_init() before request irq in sd resume.

      arm: add missing of_node_put

      for_each_child_of_node performs an of_node_get on each iteration, so
      a break out of the loop requires an of_node_put.

      The of_node_put is duplicated in front of each error return, because the
      function contains a later error return that is beyond the end of the
      for_each_child_of_node and thus doesn't need of_node_put.

      The semantic patch that fixes this problem is as follows
      (http://coccinelle.lip6.fr):

      // <smpl>
      @@
      expression root,e;

      Commit 6894258eda2f broke drivers that pass NULL as the device pointer
      to dma_alloc. The reason is that arch_dma_alloc_attrs() now calls
      dma_alloc_coherent_gfp_flags() which in turn calls
      dma_alloc_coherent_mask(), where the device pointer is dereferenced
      unconditionally.

      Fix things by moving the ISA DMA fallback device assignment before the
      call to dma_alloc_coherent_gfp_flags().

      gianfar: Fix Rx BSY error handling

      The Rx BSY error interrupt indicates that a frame was
      received and discarded due to lack of buffers, so it's
      a rx ring overflow condition and has nothing to do with
      with bad rx packets.  Use the right counter.

      BSY conditions happen when the SoC is under performance
      stress.  Doing *more* work in stress situations by trying
      to schedule NAPI is not a good idea as the stressed system
      becomes still more stressed.  The Rx interrupt is already
      at work making sure the NAPI is scheduled.
      So calling gfar_receive() here does not help.  This issue
      was present since day 1.

      gianfar: Don't enable the Filer w/o the Parser

      Under one unusual circumstance it's possible to wrongly set
      FILREN without enabling PRSDEP as well in the RCTRL register,
      against the hardware specifications.  With the default config
      this does not happen because the default Rx offloads (Rx csum
      and Rx VLAN) properly enable PRSDEP.  But if anyone disables
      all these offloads (via ethtool), we get a wrong configuration
      were the Rx flow classification and hashing, and other Filer
      based features (e.g. wake-on-filer interrupt) won't work.
      This patch fixes the issue.
      Also, account for Rx FCB insertion which happens every time
      PRSDEP is set.

      irqchip/tegra: Propagate IRQ type setting to parent

      The LIC doesn't deal with the different types of interrupts itself
      but needs to forward calls to set the appropriate type to its parent
      IRQ controller.

      Without this fix all IRQs routed through the LIC will stay at the
      initial EDGE type, while most of them should actually be level triggered.

      irqchip/armada-370-xp: Fix regression by clearing IRQ_NOAUTOEN

      Commit d17cab4451df1 ("irqchip: Kill off set_irq_flags usage") changed
      the code of armada_370_xp_mpic_irq_map() from using set_irq_flags() to
      irq_set_probe().

      While the commit log seems to imply that there are no functional
      changes, there are indeed functional changes introduced by this
      commit: the IRQ_NOAUTOEN flag is no longer cleared. This functional
      change causes a regression on Armada XP, which no longer works
      properly after suspend/resume because per-CPU interrupts remain
      disabled.

      Due to how the hardware registers work, the irq-armada-370-xp cannot
      simply save/restore a bunch of registers at suspend/resume to make
      sure that the interrupts remain in the same state after
      resuming. Therefore, it relies on the kernel to say whether the
      interrupt is disabled or not, using the irqd_irq_disabled()
      function. This was all working fine while the IRQ_NOAUTOEN flag was
      cleared.

      With the change introduced by Rob Herring in d17cab4451df1, the
      IRQ_NOAUTOEN flag is now set for all interrupts. irqd_irq_disabled()
      returns false for per-CPU interrupts, and therefore our per-CPU
      interrupts are no longer re-enabled after resume.

      This commit works around this problem by clearing again the
      IRQ_NOAUTOEN flags, so that we are back to the situation we had before
      commit d17cab4451df1. This work around is proposed as a minimal fix
      for the problem, while a better long-term solution is being worked on.

      Bluetooth: Fix locking issue during fast SCO reconnection.

      When SCO connection is requested and disconnected fast, there is a change
      that sco_sock_shutdown is going to preempt thread started in 
sco_connect_cfm.
      When this happens struct sock sk may be removed but a pointer to it is 
still
      held in sco_conn_ready, where embedded spinlock is used. If it is used, 
but
      struct sock has been removed, it will crash.

      Block connection object, which will prevent struct sock from being removed
      and give connection process chance to finish.

      Bluetooth: Fix locking issue on SCO disconnection

      Thread handling SCO disconnection may get preempted in '__sco_sock_close'
      after dropping a reference to hci_conn but before marking this as NULL
      in associated struct sco_conn. When execution returs to this thread,
      this connection will possibly be released, resulting in kernel crash

      Lock connection before this point.

      Bluetooth: Fix crash on SCO disconnect

      When disconnecting audio from the phone's side, it may happen, that
      a thread handling HCI message 'disconnection complete' will get preempted
      in 'sco_conn_del' before calling 'sco_sock_kill', still holding a pointer
      to struct sock sk. Interrupting thread started in 'sco_sock_shutdown' will
      carry on releasing resources and will eventually release struct sock.
      When execution goes back to first thread it will call sco_sock_kill using
      now invalid pointer to already destroyed socket.

      Fix is to grab a reference to the socket a release it after calling
      'sco_sock_kill'.

      Bluetooth: btmrvl: add missing of_node_put

      for_each_compatible_node performs an of_node_get on each iteration, so
      a break out of the loop requires an of_node_put.

      A simplified version of the semantic patch that fixes this problem is as
      follows (http://coccinelle.lip6.fr):

      // <smpl>

      NFC: nci: Allow the driver to set handler for core nci ops

      The driver may be required to act when some responses or
      notifications arrive. For example the NCI core does not have a
      handler for NCI_OP_CORE_GET_CONFIG_RSP. The NFCC can send a
      config response that has to be read by the driver and the packet
      may contain vendor specific data.

      The Fields Peak driver needs to take certain actions when a reset
      notification arrives (packet also not handled by the nfc core).

      The driver handlers do not interfere with the core and they are
      called after the core processes the packet.

      monitored to see whether address falls in direct mapping or kernel text
      mapping (see Documentation/x86/x86_64/mm.txt for details), if it does
      not, the kernel panics. During 1:1 mapping of EFI runtime services we 
access
      virtual addresses which are == physical addresses, thus the 1:1 mapping
      and these addresses do not fall in either of the above two regions and

      ====================
      tipc: improve broadcast implementation

      The TIPC broadcast link implementation is currently complex and hard to
      follow. It also incurs some amount of code and structure duplication,
      something that can be reduced significantly with a little effort.

      This commit series introduces a number of improvements which address
      both the locking structure, the code/structure duplication issue, and
      the overall readbility of the code.

      The series consists of three main parts:

      1-7: Adaptation to the new link structure, and preparation for the next
           step. In particular, we want the broadcast transmission link to
           have a life cycle that is longer than any of its potential (unicast
           and broadcast receive links) users. This eliminates the need to
           always test for the presence of this link before accessing it.

      8-10: This is what is really new in this series. Commit #9 is by far
            the largest and most important one, because it moves most of
            the broadcast functionality into link.c, partially reusing the
            fields and functionality of the unicast link. The removal of
            the "node_map" infrastructure in commit #10 is also an important
            achievement.

      11-16: Some improvements leveraging the changes made in the previous
             commits.

      The series needs commit 53387c4e22ac ("tipc: extend broadcast link window 
size")
      and commit e53567948f82 ("tipc: conditionally expand buffer headroom over 
udp tunnel")
      which are both present in 'net' but not yet in 'net-next', to apply 
cleanly.

      tipc: ensure binding table initial distribution is sent via first link

      Correct synchronization of the broadcast link at first contact between
      two nodes is dependent on the assumption that the binding table "bulk"
      update passes via the same link as the initial broadcast syncronization
      message, i.e., via the first link that is established.

      This is not guaranteed in the current implementation. If two link
      come up very close to each other in time, the "bulk" may quite well
      pass via the second link, and hence void the guarantee of a correct
      initial synchronization before the broadcast link is opened.

      This commit makes two small changes to strengthen this guarantee.

      1) We let the second established link occupy slot 1 of the
         "active_links" array, while the first link will retain slot 0.
         (This is in reality a cosmetic change, we could just as well keep
          the current, opposite order)

      2) We let the name distributor always use link selector/slot 0 when
         it sends it binding table updates.

      The extra traffic bias on the first link caused by this change should
      be negligible, since binding table updates constitutes a very small
      fraction of the total traffic.

      tipc: eliminate link's reference to owner node

      With the recent commit series, we have established a one-way dependency
      between the link aggregation (struct tipc_node) instances and their
      pertaining tipc_link instances. This has enabled quite significant code
      and structure simplifications.

      In this commit, we eliminate the field 'owner', which points to an
      instance of struct tipc_node, from struct tipc_link, and replace it with
      a pointer to struct net, which is the only external reference now needed
      by a link instance.

      tipc: let neighbor discoverer tranmsit consumable buffers

      The neighbor discovery function currently uses the function

      tipc: simplify bearer level broadcast

      Until now, we have been keeping track of the exact set of broadcast
      destinations though the help structure tipc_node_map. This leads us to
      have to maintain a whole infrastructure for supporting this, including
      a pseudo-bearer and a number of functions to manipulate both the bearers
      and the node map correctly. Apart from the complexity, this approach is
      also limiting, as struct tipc_node_map only can support cluster local
      broadcast if we want to avoid it becoming excessively large. We want to
      eliminate this limitation, in order to enable introduction of scoped
      multicast in the future.

      A closer analysis reveals that it is unnecessary maintaining this "full
      set" overview; it is sufficient to keep a counter per bearer, indicating
      how many nodes can be reached via this bearer at the moment. The protocol
      is now robust enough to handle transitional discrepancies between the
      nominal number of reachable destinations, as expected by the broadcast
      protocol itself, and the number which is actually reachable at the
      moment. The initial broadcast synchronization, in conjunction with the
      retransmission mechanism, ensures that all packets will eventually be
      acknowledged by the correct set of destinations.

      This commit introduces these changes.

      tipc: let broadcast packet reception use new link receive function

      The code path for receiving broadcast packets is currently distinct
      from the unicast path. This leads to unnecessary code and data
      duplication, something that can be avoided with some effort.

      We now introduce separate per-peer tipc_link instances for handling
      broadcast packet reception. Each receive link keeps a pointer to the
      common, single, broadcast link instance, and can hence handle release
      and retransmission of send buffers as if they belonged to the own
      instance.

      Furthermore, we let each unicast link instance keep a reference to both
      the pertaining broadcast receive link, and to the common send link.
      This makes it possible for the unicast links to easily access data for
      broadcast link synchronization, as well as for carrying acknowledges for
      received broadcast packets.

      tipc: introduce capability bit for broadcast synchronization

      Until now, we have tried to support both the newer, dedicated broadcast
      synchronization mechanism along with the older, less safe, RESET_MSG/
      ACTIVATE_MSG based one. The latter method has turned out to be a hazard
      in a highly dynamic cluster, so we find it safer to disable it completely
      when we find that the former mechanism is supported by the peer node.

      For this purpose, we now introduce a new capabability bit,
      TIPC_BCAST_SYNCH, to inform any peer nodes that dedicated broadcast
      syncronization is supported by the present node. The new bit is conveyed
      between peers in the 'capabilities' field of neighbor discovery messages.

      tipc: make struct tipc_link generic to support broadcast

      Realizing that unicast is just a special case of broadcast, we also see
      that we can go in the other direction, i.e., that modest changes to the
      current unicast link can make it generic enough to support broadcast.

      The following changes are introduced here:

      - A new counter ("ackers") in struct tipc_link, to indicate how many
        peers need to ack a packet before it can be released.
      - A corresponding counter in the skb user area, to keep track of how
        many peers a are left to ack before a buffer can be released.
      - A new counter ("acked"), to keep persistent track of how far a peer
        has acked at the moment, i.e., where in the transmission queue to
        start updating buffers when the next ack arrives. This is to avoid
        double acknowledgements from a peer, with inadvertent relase of
        packets as a result.
      - A more generic tipc_link_retrans() function, where retransmit starts
        from a given sequence number, instead of the first packet in the
        transmision queue. This is to minimize the number of retransmitted
        packets on the broadcast media.

      When the new functionality is taken into use in the next commits,
      we expect it to have minimal effect on unicast mode performance.

      tipc: use explicit allocation of broadcast send link

      The broadcast link instance (struct tipc_link) used for sending is
      currently aggregated into struct tipc_bclink. This means that we cannot
      use the regular tipc_link_create() function for initiating the link, but
      do instead have to initiate numerous fields directly from the
      bcast_init() function.

      We want to reduce dependencies between the broadcast functionality
      and the inner workings of tipc_link. In this commit, we introduce
      a new function tipc_bclink_create() to link.c, and allocate the
      instance of the link separately using this function.

      tipc: make link implementation independent from struct tipc_bearer

      In reality, the link implementation is already independent from
      struct tipc_bearer, in that it doesn't store any reference to it.
      However, we still pass on a pointer to a bearer instance in the
      function tipc_link_create(), just to have it extract some
      initialization information from it.

      I later commits, we need to create instances of tipc_link without
      having any associated struct tipc_bearer. To facilitate this, we
      want to extract the initialization data already in the creator
      function in node.c, before calling tipc_link_create(), and pass
      this info on as individual parameters in the call.

      This commit introduces this change.

      tipc: create broadcast transmission link at namespace init

      The broadcast transmission link is currently instantiated when the
      network subsystem is started, i.e., on order from user space via netlink.

      This forces the broadcast transmission code to do unnecessary tests for
      the existence of the transmission link, as well in single mode node as
      in network mode.

      In this commit, we do instead create the link during initialization of
      the name space, and remove it when it is stopped. The fact that the
      transmission link now has a guaranteed longer life cycle than any of its
      potential clients paves the way for further code simplifcations
      and optimizations.

      definitions.

      In this commit, we move as many of those definitions as is currently
      possible to the file bcast.c.

      We also rename the structure 'tipc_bclink' to 'tipc_bc_base', both
      since the name does not correctly describe the contents of this
      struct, and will do so even less in the future, and because we want
      to use the term 'link' more appropriately in the functionality
      introduced later in this series.

      Finally, we rename a couple of functions, such as tipc_bclink_xmit()
      and others that will be kept in the future, to include the term 'bcast'
      instead.

      There are no functional changes in this commit.

      rtl8xxxu: move devices supported by rtlwifi under UNTESTED config

      There are still four devices which are currently supported both by the new
      rtl8xxxu driver and rtlwifi. To not break existing setups enable the 
support
      for these four devices only when CONFIG_RTL8XXXU_UNTESTED is turned on.

      Once rtl8xxxu support is found to be good enough the devices can be 
removed
      from rtlwifi and enabled by default in rtl8xxxu.

      md/raid10: fix the 'new' raid10 layout to work correctly.

      In Linux 3.9 we introduce a new 'far' layout for RAID10 which was
      supposed to rotate the replicas differently and so provide better
      resilience.  In particular it could survive more combinations of 2
      drive failures.

      Unfortunately. due to a coding error, this some did what was wanted,
      sometimes improved less than we hoped, and sometimes - in very
      unlikely circumstances - put multiple replicas on the same device so
      the redundancy was harmed.

      No public user-space tool has created arrays using this layout so it
      is very unlikely that zero-redundancy arrays actually exist.  Probably
      no arrays using any form of the new layout exist.  But we cannot be
      certain.

      So use another bit in the 'layout' number and introduce a bug-fixed
      version of the layout.
      Also when assembling an array, if it has a zero-redundancy layout,
      give a warning.

      md/raid10: don't clear bitmap bit when bad-block-list write fails.

      When a write fails and a bad-block-list is present, we can
      update the bad-block-list instead of writing the data.  If
      this succeeds then it is OK clear the relevant bitmap-bit as
      no further 'sync' of the block is needed.

      However if writing the bad-block-list fails then we need to
      treat the write as failed and particularly must not clear
      the bitmap bit.  Otherwise the device can be re-added (after
      any hardware connection issues are resolved) and because the
      relevant bit in the bitmap is clear, that block will not be
      resynced.  This leads to data corruption.

      We already delay the final bio_endio() on the write until
      the bad-block-list is written so that when the write
      returns: either that data is safe, the bad-block record is
      safe, or the fact that the device is faulty is safe.
      However we *don't* delay the clearing of the bitmap, so the
      bitmap bit can be recorded as cleared before we know if the
      bad-block-list was written safely.

      So: delay that until the write really is safe.
      i.e. move the call to close_write() until just before
      calling bio_endio(), and recheck the 'is array degraded'
      status before making that call.

      This bug goes back to v3.1 when bad-block-lists were
      introduced, though it only affects arrays created with
      mdadm-3.3 or later as only those have bad-block lists.

      Backports will require at least
      Commit: 95af587e95aa ("md/raid10: ensure device failure recorded before 
write request returns.")
      as well.  I'll send that to 'stable' separately.

      Note that of the two tests of R10BIO_WriteError that this
      patch adds, the first is certain to fail and the second is
      certain to succeed.  However doing it this way makes the
      patch more obviously correct.  I will tidy the code up in a
      future merge window.

      perf tools: Provide help for subset of options

      Some tools have a lot of options, so, providing a way to show help just
      for some of them may come handy:

        $ perf report -h --tui

         Usage: perf report [<options>]

              --tui             Use the TUI interface

              --tui             Use the TUI interface

        $

      Using it with perf bash completion is also handy, just make sure you
      source the needed file:

        $ . ~/git/linux/tools/perf/perf-completion.sh

      Then press tab/tab after -- to see a list of options, put them after -h
      and only the options chosen will have its help presented:

        Six serious fixes:

         - Hold the mutex around the find and corresponding update of our gid

         - The ifa list is rcu protected, copy its contents under rcu to avoid
           using a freed structure

         - On error, netdev might be null, so check it before trying to
           release it

         - On init, if workqueue alloc fails, fail init

         - The new demux patches exposed a bug in mlx5 and ipath drivers, we
           need to use the payload P_Key to determine the P_Key the packet
           arrived on because the hardware doesn't tell us the truth

         - Due to a couple convoluted error flows, it is possible for the CM
           to trigger a use_after_free and a double_free of rb nodes.  Add two
           checks to prevent that.  This code has worked for 10+ years.  It is
           likely that some of the recent changes have caused this issue to
           surface.  The current patch will protect us from nasty events for

       "A final set of fixes for 4.3.

        It is (again) bigger than I would have liked, but it's all been
        through the testing mill and has been carefully reviewed by multiple
        parties.  Each fix is either a regression fix for this cycle, or is
        marked stable.  You can scold me at KS.  The pull request contains:

         - Three simple fixes for NVMe, fixing regressions since 4.3.  From
           Arnd, Christoph, and Keith.

         - A single xen-blkfront fix from Cathy, fixing a NULL dereference if
           an error is returned through the staste change callback.

         - Fixup for some bad/sloppy code in nbd that got introduced earlier
           in this cycle.  From Markus Pargmann.

         - A blk-mq tagset use-after-free fix from Junichi.

         - A backing device lifetime fix from Tejun, fixing a crash.

         - And finally, a set of regression/stable fixes for cgroup writeback
           from Tejun"

      dm cache: the CLEAN_SHUTDOWN flag was not being set

      If the CLEAN_SHUTDOWN flag is not set when a cache is loaded then all 
cache
      blocks are marked as dirty and a full writeback occurs.

      __commit_transaction() is responsible for setting/clearing
      CLEAN_SHUTDOWN (based the flags_mutator that is passed in).

      Fix this issue, of the cache's on-disk flags being wrong, by making sure
      __commit_transaction() does not reset the flags after the mutator has
      altered the flags in preparation for them being serialized to disk.

      before:

      sb_flags = mutator(le32_to_cpu(disk_super->flags));
      disk_super->flags = cpu_to_le32(sb_flags);
      disk_super->flags = cpu_to_le32(cmd->flags);

      after:

      disk_super->flags = cpu_to_le32(cmd->flags);
      sb_flags = mutator(le32_to_cpu(disk_super->flags));
      disk_super->flags = cpu_to_le32(sb_flags);

      dm btree remove: fix a bug when rebalancing nodes after removal

      Commit 4c7e309340ff ("dm btree remove: fix bug in redistribute3") wasn't
      a complete fix for redistribute3().

      The redistribute3 function takes 3 btree nodes and shares out the entries
      evenly between them.  If the three nodes in total contained
      (MAX_ENTRIES * 3) - 1 entries between them then this was erroneously 
getting
      rebalanced as (MAX_ENTRIES - 1) on the left and right, and (MAX_ENTRIES + 
1) in
      the center.

      Fix this issue by being more careful about calculating the target number
      of entries for the left and right nodes.

      rbd: prevent kernel stack blow up on rbd map

      Mapping an image with a long parent chain (e.g. image foo, whose parent
      is bar, whose parent is baz, etc) currently leads to a kernel stack
      overflow, due to the following recursion in the reply path:

        rbd_osd_req_callback()
          rbd_obj_request_complete()
            rbd_img_obj_callback()
              rbd_img_parent_read_callback()
                rbd_obj_request_complete()
                  ...

      Limit the parent chain to 16 images, which is ~5K worth of stack.  When
      the above recursion is eliminated, this limit can be lifted.

      rbd: don't leak parent_spec in rbd_dev_probe_parent()

      Currently we leak parent_spec and trigger a "parent reference
      underflow" warning if rbd_dev_create() in rbd_dev_probe_parent() fails.
      The problem is we take the !parent out_err branch and that only drops
      refcounts; parent_spec that would've been freed had we called
      rbd_dev_unparent() remains and triggers rbd_warn() in
      rbd_dev_parent_put() - at that point we have parent_spec != NULL and
      parent_ref == 0, so counter ends up being -1 after the decrement.

      Redo rbd_dev_probe_parent() to fix this.

      Intel Wired LAN Driver Updates 2015-10-23

      This series contains updates to i40e, i40evf, if_link, ixgbe and ixgbevf.

      Anjali adds a workaround to drop any flow control frames from being
      transmitted from any VSI, so that a malicious VF cannot send flow control
      or PFC packets out on the wire.  Also fixed a bug in debugfs by grabbing
      the filter list lock before adding or deleting a filter.

      Akeem fixes an issue where we were unconditionally returning VEB bridge
      mode before allowing LB in the add VSI routine, resolve by checking if
      the bridge is actually in VEB mode first.

      Mitch fixed an issue where the incorrect structure was being used for
      VLAN filter list, which meant the VLAN filter list did not get
      processed correctly and VLAN filters would not be re-enabled after any
      kind of reset.

      Helin fixed a problem of possibly getting inconsistent flow control
      status after a PF reset.  The issue was requested_mode was being set
      with a default value during probe, but the hardware state could be a
      different value from this mode.

      Carolyn fixed a problem where the driver output of the OEM version
      string varied from the other tools.

      Jean Sacren fixes up kernel documentation by fixing function header
      comments to match actual variables used in the functions.  Also
      cleaned up variable initialization, when the variable would be
      over-written immediately.

      Hiroshi Shimanoto provides three patches to add "trusted" VF by adding
      netlink directives and an NDO entry.  Then implement these new controls
      in ixgbe and ixgbevf.  This series has gone through several iterations
      to address all the suggested community changes and concerns.

      mpls: flow-based multipath selection

      Change the selection of a multipath route to use a flow-based
      hash. This more suitable for traffic sensitive to reordering within a
      flow (e.g. TCP, L2VPN) and whilst still allowing a good distribution
      of traffic given enough flows.

      Selection of the path for a multipath route is done using a hash of:
      1. Label stack up to MAX_MP_SELECT_LABELS labels or up to and
         including entropy label, whichever is first.
      2. 3-tuple of (L3 src, L3 dst, proto) from IPv4/IPv6 header in MPLS
         payload, if present.

      Naturally, a 5-tuple hash using L4 information in addition would be
      possible and be better in some scenarios, but there is a tradeoff
      between looking deeper into the packet to achieve good distribution,
      and packet forwarding performance, and I have erred on the side of the
      latter as the default.

      mpls: multipath route support

      This patch adds support for MPLS multipath routes.

      Includes following changes to support multipath:
      - splits struct mpls_route into 'struct mpls_route + struct mpls_nh'

      - 'struct mpls_nh' represents a mpls nexthop label forwarding entry

      - moves mpls route and nexthop structures into internal.h

      - A mpls_route can point to multiple mpls_nh structs

      - the nexthops are maintained as a array (similar to ipv4 fib)

      - In the process of restructuring, this patch also consistently changes
        all labels to u8

      - Adds support to parse/fill RTA_MULTIPATH netlink attribute for
      multipath routes similar to ipv4/v6 fib

      - In this patch, the multipath route nexthop selection algorithm
      simply returns the first nexthop. It is replaced by a
      hash based algorithm from Robert Shearman in the next patch

      - mpls_route_update cleanup: remove 'dev' handling in mpls_route_update.
      mpls_route_update though implemented to update based on dev, it was
      never used that way. And the dev handling gets tricky with multiple
      nexthops. Cannot match against any single nexthops dev. So, this patch
      removes the unused 'dev' handling in mpls_route_update.

      - dead route/path handling will be implemented in a subsequent patch

      Example:

      $ip -f mpls route add 100 nexthop as 200 via inet 10.1.1.2 dev swp1 \
                      nexthop as 700 via inet 10.1.1.6 dev swp2 \
                      nexthop as 800 via inet 40.1.1.2 dev swp3

      $ip  -f mpls route show
      100
              nexthop as to 200 via inet 10.1.1.2  dev swp1
              nexthop as to 700 via inet 10.1.1.6  dev swp2

      net: sysctl: fix a kmemleak warning

      the returned buffer of register_sysctl() is stored into net_header
      variable, but net_header is not used after, and compiler maybe
      optimise the variable out, and lead kmemleak reported the below warning

      Merge branch 'mdiobus_nested_read_write'

      Neil Armstrong says:

      ====================
      Refactor nested mdiobus read/write functions

      In order to avoid locked signal false positive for nested mdiobus
      read/write calls, nested code was introduced in mv88e6xxx and
      mdio-mux.
      But mv88e6060 also needs such nested mdiobus read/write calls.
      For sake of refactoring, introduce nested variants of mdiobus read/write
      and make them used by mv88e6xxx and mv88e6060.
      In a next patch, mdio-mux should also use these variant calls.

      ixgbe, ixgbevf: Add new mbox API xcast mode

      The limitation of the number of multicast address for VF is not enough
      for the large scale server with SR-IOV feature. IPv6 requires the 
multicast
      MAC address for each IP address to handle the Neighbor Solicitation
      message. We couldn't assign over 30 IPv6 addresses to a single VF.

      This patch introduces the new mailbox API, IXGBE_VF_UPDATE_XCAST_MODE,
      to update multicast mode of VF. This adds 3 modes;
        - NONE     only L2 exact match addresses or Flow Director enabled
        - MULTI    BAM and ROMPE set
        - ALLMULTI BAM, ROMPE and MPE set

      If a guest VF user wants over 30 MAC multicast addresses, set IFF_ALLMULTI
      to request PF to update xcast mode to enable VF multicast promiscuous 
mode.

      On the other hand, enabling VF multicast promiscuous mode may affect
      security and performance in the network of the NIC. Only trusted VF can
      enable multicast promiscuous mode. The behavior of untrusted VF is the
      same as previous version.

      tcp/dccp: fix hashdance race for passive sessions

      Multiple cpus can process duplicates of incoming ACK messages
      matching a SYN_RECV request socket. This is a rare event under
      normal operations, but definitely can happen.

      Only one must win the race, otherwise corruption would occur.

      To fix this without adding new atomic ops, we use logic in
      inet_ehash_nolisten() to detect the request was present in the same
      ehash bucket where we try to insert the new child.

      If request socket was not found, we have to undo the child creation.

      This actually removes a spin_lock()/spin_unlock() pair in
      reqsk_queue_unlink() for the fast path.

      Fixes: e994b2f0fb92 ("tcp: do not lock listener to process SYN packets")
      Fixes: 079096f103fa ("tcp/dccp: install syn_recv requests into ehash

      ppp: fix pppoe_dev deletion condition in pppoe_release()

      We can't rely on PPPOX_ZOMBIE to decide whether to clear po->pppoe_dev.
      PPPOX_ZOMBIE can be set by pppoe_disc_rcv() even when po->pppoe_dev is
      NULL. So we have no guarantee that (sk->sk_state & PPPOX_ZOMBIE) implies
      (po->pppoe_dev != NULL).
      Since we're releasing a PPPoE socket, we want to release the pppoe_dev
      if it exists and reset sk_state to PPPOX_DEAD, no matter the previous
      value of sk_state. So we can just check for po->pppoe_dev and avoid any
      assumption on sk->sk_state.

      amd-xgbe: Use wmb before updating current descriptor count

      The code currently uses the lightweight dma_wmb barrier before updating
      the current descriptor count. Under heavy load, the Tx cleanup routine
      was seeing the updated current descriptor count before the updated
      descriptor information. As a result, the Tx descriptor was being cleaned
      up before it was used because it was not "owned" by the hardware yet,
      resulting in a Tx queue hang.

      Using the wmb barrier insures that the descriptor is updated before the
      descriptor counter preventing the Tx queue hang. For extra insurance,
      the Tx cleanup routine is changed to grab the current decriptor count on
      entry and uses that initial value in the processing loop rather than
      trying to chase the current value.

      ipv4: implement support for NOPREFIXROUTE ifa flag for ipv4 address

      Currently adding a new ipv4 address always cause the creation of the
      related network route, with default metric. When a host has multiple
      interfaces on the same network, multiple routes with the same metric
      are created.

      If the userspace wants to set specific metric on each routes, i.e.
      giving better metric to ethernet links in respect to Wi-Fi ones,
      the network routes must be deleted and recreated, which is error-prone.

      This patch implements the support for IFA_F_NOPREFIXROUTE for ipv4
      address. When an address is added with such flag set, no associated
      network route is created, no network route is deleted when
      said IP is gone and it's up to the user space manage such route.

      overflow-arith: begin to add support for overflow builtins functions

      I add a new header, linux/overflow-arith.h, as the central place to add
      overflow and wrap-around checking functions. The reason I am doing so
      is that it can make use of compiler supported builtin functions which
      can leverage hardware.

      As I need this for a fix in the ipv6 stack, which is also included in
      this series, I propose to add it sooner than later over Davem's net
      tree. This is also the reason why I start slowly with only the one
      function I need at this time.

      ipv6: protect mtu calculation of wrap-around and infinite loop by 
rounding issues

      Raw sockets with hdrincl enabled can insert ipv6 extension headers
      right into the data stream. In case we need to fragment those packets,
      we reparse the options header to find the place where we can insert
      the fragment header. If the extension headers exceed the link's MTU we
      actually cannot make progress in such a case.

      Instead of ending up in broken arithmetic or rounding towards 0 and
      entering an endless loop in ip6_fragment, just prevent those cases by
      aborting early and signal -EMSGSIZE to user space.

      overflow-arith: begin to add support for overflow builtin functions

      The idea of the overflow-arith.h header is to collect overflow checking
      functions in one central place.

      If gcc compiler supports the __builtin_overflow_* builtins we use them
      because they might give better performance, otherwise the code falls
      back to normal overflow checking functions.

      The builtin_overflow functions are supported by gcc-5 and clang. The
      matter of supporting clang is to just provide a corresponding
      CC_HAVE_BUILTIN_OVERFLOW, because the specific overflow checking builtins
      don't differ between gcc and clang.

      I just provide overflow_usub function here as I intend this to get merged
      into net, more functions will definitely follow as they are needed.

      tcp: allow dctcp alpha to drop to zero

      If alpha is strictly reduced by alpha >> dctcp_shift_g and if alpha is 
less
      than 1 << dctcp_shift_g, then alpha may never reach zero. For example,
      given shift_g=4 and alpha=15, alpha >> dctcp_shift_g yields 0 and alpha
      remains 15. The effect isn't noticeable in this case below cwnd=137, but
      could gradually drive uncongested flows with leftover alpha down to
      cwnd=137. A larger dctcp_shift_g would have a greater effect.

      This change causes alpha=15 to drop to 0 instead of being decrementing by 
1
      as it would when alpha=16. However, it requires one less conditional to
      implement since it doesn't have to guard against subtracting 1 from 0U. A
      decay of 15 is not unreasonable since an equal or greater amount occurs at
      alpha >= 240.

       "Running tests on other changes, the system locked up due to lots of
        warnings.  It was caused by the stack tracer triggering a warning
        about using rcu_dereference() when RCU was not watching.  This can
        happen due to the fact that the stack tracer uses the function tracer
        to check each function, and there are functions that may be called and
        traced when RCU stopped watching.  Namely when a function is called
        just before going idle or to userspace and after RCU stopped watching
        that current CPU.

        The first patch makes sure that RCU is watching when the stack tracer
        uses RCU.  The second patch is to make sure that the stack tracer does
        not get called by functions in NMI, as it's not NMI safe"

      lib/Kconfig.debug: disable -Wframe-larger-than warnings with KASAN=y

      When the kernel compiled with KASAN=y, GCC adds redzones for each
      variable on stack.  This enlarges function's stack frame and causes:

        'warning: the frame size of X bytes is larger than Y bytes'

      The worst case I've seen for now is following:

         ../net/wireless/nl80211.c: In function `nl80211_send_wiphy':
         ../net/wireless/nl80211.c:1731:1: warning: the frame size of 5448 
bytes is larger than 2048 bytes [-Wframe-larger-than=]

      That kind of warning becomes useless with KASAN=y.  It doesn't
      necessarily indicate that there is some problem in the code, thus we
      should turn it off.

      (The KASAN=y stack size in increased from 16k to 32k for this reason)

      mm: make sendfile(2) killable

      Currently a simple program below issues a sendfile(2) system call which
      takes about 62 days to complete in my test KVM instance.

              int fd;
              off_t off = 0;

              fd = open("file", O_RDWR | O_TRUNC | O_SYNC | O_CREAT, 0644);
              ftruncate(fd, 2);
              lseek(fd, 0, SEEK_END);
              sendfile(fd, fd, &off, 0xfffffff);

      Now you should not ask kernel to do a stupid stuff like copying 256MB in
      2-byte chunks and call fsync(2) after each chunk but if you do, sysadmin
      should have a way to stop you.

      We actually do have a check for fatal_signal_pending() in
      generic_perform_write() which triggers in this path however because we
      always succeed in writing something before the check is done, we return
      value > 0 from generic_perform_write() and thus the information about
      signal gets lost.

      Fix the problem by doing the signal check before writing anything.  That
      way generic_perform_write() returns -EINTR, the error gets propagated up
      and the sendfile loop terminates early.

      thp: use is_zero_pfn() only after pte_present() check

      Use is_zero_pfn() on pteval only after pte_present() check on pteval
      (It might be better idea to introduce is_zero_pte() which checks
      pte_present() first).

      Otherwise when working on a swap or migration entry and if pte_pfn's
      result is equal to zero_pfn by chance, we lose user's data in
      __collapse_huge_page_copy().  So if you're unlucky, the application
      segfaults and finally you could see below message on exit:

      kmod: don't run async usermode helper as a child of kworker thread

      call_usermodehelper_exec_sync() does fork() + wait() with "unignored"
      SIGCHLD.  What we have missed is that this worker thread can have other
      children previously forked by call_usermodehelper_exec_work() without
      UMH_WAIT_PROC.  If such a child exits in between it becomes a zombie
      because auto-reaping only works if SIGCHLD is ignored, and nobody can
      reap it (unless/until this worker thread exits too).

      Change the !UMH_WAIT_PROC case to use CLONE_PARENT.

      Note: this is only first step.  All PF_KTHREAD tasks, even created by
      kernel_thread() should have ->parent == kthreadd by default.

      xfrm4: Fix header checks in _decode_session4.

      We skip the header informations if the data pointer points
      already behind the header in question for some protocols.
      This is because we call pskb_may_pull with a negative value
      converted to unsigened int from pskb_may_pull in this case.
      Skipping the header informations can lead to incorrect policy
      lookups, so fix it by a check of the data pointer position
      before we call pskb_may_pull.

      ASoC: Fixes for v4.3

      xfrm: Fix unaligned access to stats in copy_to_user_state()

      On sparc, deleting established SAs (e.g., by restarting ipsec)
      results in unaligned access messages via xfrm_del_sa ->
      km_state_notify -> xfrm_send_state_notify().

      Even though struct xfrm_usersa_info is aligned on 8-byte boundaries,
      netlink attributes are fundamentally only 4 byte aligned, and this
      cannot be changed for nla_data() that is passed up to userspace.
      As a result, the put_unaligned() macro needs to be used to
      set up potentially unaligned fields such as the xfrm_stats in
      copy_to_user_state()

      openvswitch: Fix egress tunnel info.

      While transitioning to netdev based vport we broke OVS
      feature which allows user to retrieve tunnel packet egress
      information for lwtunnel devices.  Following patch fixes it
      by introducing ndo operation to get the tunnel egress info.
      Same ndo operation can be used for lwtunnel devices and compat
      ovs-tnl-vport devices. So after adding such device operation
      we can remove similar operation from ovs-vport.

      bnxt_en: New Broadcom ethernet driver.

      Broadcom ethernet driver for the new family of NetXtreme-C/E
      ethernet devices.

      v5:
        - Removed empty blank lines at end of files (noted by David Miller).
        - Moved busy poll helper functions to bnxt.h to at least make the
          .c file look less cluttered with #ifdef (noted by Stephen Hemminger).

      v4:
        - Broke up 2 long message strings with "\n" (suggested by John Linville)
        - Constify an array of strings (suggested by Stephen Hemminger)
        - Improve bnxt_vf_pciid() (suggested by Stephen Hemminger)
        - Use PCI_VDEVICE() to populate pci_device_id table for more compact
          source.

      v3:
        - Fixed 2 more sparse warnings.
        - Removed some unused structures in .h files.

      v2:
        - Fixed all kbuild test robot reported warnings.
        - Fixed many of the checkpatch.pl errors and warnings.
        - Fixed the Kconfig description (noted by Dmitry Kravkov).

      when printing stats.  Then fixed the fact that the driver was printing
      a message about not being able to assign VMDq because a lack of MSI-X

      initialized a variable.

      perf annotate: Don't die() when finding an invalid config option

      The perf_config() infrastructure we inherited from git calls die() when
      the provided config callback returns -1, meaning some key in a config
      section is unexpected, that seems ok for a stdio based tool, but in
      --tui we end up messing up the output, so just tell the user about the
      error, wait for a keystroke and return 0, being more resilient and
      proceeding with what we managed to parse.

      That die() needs to die, tho :-)

      %ps/%pS is supposed to do, so use the same code for %ps/%pS.

      [media] m88ds3103: use own reg update_bits() implementation

      Device stopped to tuning some channels after regmap conversion.
      Reason is that regmap_update_bits() works a bit differently for
      partially volatile registers than old homemade routine. Return
      back to old routine in order to fix issue.

      [media] rtl28xxu: fix control message flaws

      Add lock to prevent concurrent access for control message as control
      message function uses shared buffer. Without the lock there may be
      remote control polling which messes the buffer causing IO errors.
      Increase buffer size and add check for maximum supported message
      length.

      The variable err was never initialized, that means we had been checking
      a garbage value in the for loop. Moreover if the segment is not outside

      Initialize it to 0 so that on success we return the value and no need to
      check in the for loop also as it is initially 0 and whenever that value
      changes we have done a break from the loop.

      ARM: dts: fix gpio-keys wakeup-source property

      The keyboard driver for GPIO buttons(gpio-keys) checks for one of the
      two boolean properties to enable gpio buttons as wakeup source:
      1. "wakeup-source" or
      2. the legacy "gpio-key,wakeup"

      However juno, ste-snowball and emev2-kzm9d dts file have a undetected
      "wakeup" property to indictate the wakeup source.

      This patch fixes it by making use of "wakeup-source" property.

      2) Fix some header checks in _decode_session6.
         We skip the header informations if the data pointer points
         already behind the header in question for some protocols.
         This is because we call pskb_may_pull with a negative value
         converted to unsigened int from pskb_may_pull in this case.
         Skipping the header informations can lead to incorrect policy
         lookups. From Mathias Krause.

      3) Allow to change the replay threshold and expiry timer of a
         state without having to set other attributes like replay
         counter and byte lifetime. Changing these other attributes
         may break the SA. From Michael Rossberg.

      4) Fix pmtu discovery for local generated packets.
         We may fail dispatch to the inner address family.
         As a reault, the local error handler is not called

      Not all switch chips provide a Get Next kind of operation to dump FDB

      It is preferred to let the driver handle the dump operation the way it 
works
      best for the chip. Thus, drop port_fdb_getnext and implement the 
port_fdb_dump
      operation in DSA, which pushes the switchdev FDB dump callback down to the

      mISDN: fix OOM condition for sending queued I-Frames

      The old code did not check the return value of skb_clone().
      The extra skb_clone() is not needed at all, if using 
skb_realloc_headroom()
      instead, which gives us a private copy with enough headroom as well.
      We need to requeue the original skb if the call failed, because we cannot
      inform upper layers about the data loss. Restructure the code to minimise
      rollback effort if it happens.
      This fix kernel bug #86091

      VSOCK: sock_put wasn't safe to call in interrupt context

      In the vsock vmci_transport driver, sock_put wasn't safe to call
      in interrupt context, since that may call the vsock destructor
      which in turn calls several functions that should only be called
      from process context. This change defers the callling of these
      functions  to a worker thread. All these functions were
      deallocation of resources related to the transport itself.

      Furthermore, an unused callback was removed to simplify the
      cleanup.

      Multiple customers have been hitting this issue when using
      VMware tools on vSphere 2015.

      Also added a version to the vmci transport module (starting from
      1.0.2.0-k since up until now it appears that this module was
      sharing version with vsock that is currently at 1.0.1.0-k).

      netlink: fix locking around NETLINK_LIST_MEMBERSHIPS

      Currently, NETLINK_LIST_MEMBERSHIPS grabs the netlink table while copying
      the membership state to user-space. However, grabing the netlink table is
      effectively a write_lock_irq(), and as such we should not be triggering
      page-faults in the critical section.

      This can be easily reproduced by the following snippet:
          int s = socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE);
          void *p = mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, 
-1, 0);
          int r = getsockopt(s, 0x10e, 9, p, (void*)((char*)p + 4092));

      This should work just fine, but currently triggers EFAULT and a possible
      WARN_ON below handle_mm_fault().

      Fix this by reducing locking of NETLINK_LIST_MEMBERSHIPS to a read-side
      lock. The write-lock was overkill in the first place, and the read-lock
      allows page-faults just fine.

      bpf_perf_event_output helper

      It was almost perfect with exception that all bpf programs would sent

      This patch set takes different approach by letting user space
      open independent PERF_COUNT_SW_BPF_OUTPUT events, so that program

      bpf: introduce bpf_perf_event_output() helper

      This helper is used to send raw data from eBPF program into
      special PERF_TYPE_SOFTWARE/PERF_COUNT_SW_BPF_OUTPUT perf_event.
      User space needs to perf_event_open() it (either for one or all cpus) and
      store FD into perf_event_array (similar to bpf_perf_event_read() helper)
      before eBPF program can send data into it.

      Today the programs triggered by kprobe collect the data and either store
      it into the maps or print it via bpf_trace_printk() where latter is the 
debug
      facility and not suitable to stream the data. This new helper replaces
      such bpf_trace_printk() usage and allows programs to have dedicated
      channel into user space for post-processing of the raw data collected.

      ipvlan: read direct ifindex instead of iflink

      In the ipv4 outbound path of an ipvlan device in l3 mode, the ifindex is
      being grabbed from dev_get_iflink. This works for the physical device
      case, since as the documentation of that function notes: "Physical
      interfaces have the same 'ifindex' and 'iflink' values.".  However, if
      the master device is a veth, and the pairs are in separate net
      namespaces, the route lookup will fail with -ENODEV due to outer veth
      pair being in a separate namespace from the ipvlan master/routing
      namespace.

        ns0    |   ns1    |   ns2
       veth0a--|--veth0b--|--ipvl0

      In ipvlan_process_v4_outbound(), a packet sent from ipvl0 in the above
      configuration will pass fl.flowi4_oif == veth0a to
      ip_route_output_flow(), but *net == ns1.

      Notice also that ipv6 processing is not using iflink. Since there is a
      discrepancy in usage, fixup both v4 and v6 case to use local dev
      variable.

      Tested this with l3 ipvlan on top of veth, as well as with single
      physical interface in the top namespace.

      store interrupt controller data which caused errors while using
      gpiochip_set_chained_irqchip.

      Update XLP GPIO driver to use the gpiolib irqchip helpers.
      And add missing depends on OF_GPIO in Kconfig.

      genirq: Make the cpuhotplug migration code less noisy

      The original arm code has a pr_debug() statement for the case where
      the irq chip has no set_affinity() callback. That's sufficient for
      debugging and we really don't want to spam dmesg with useless warnings
      for the normal case.

      ieee802154: 6lowpan: fix memory leak

      Looking at current situation of memory management in 6lowpan receive
      function I detected some invalid handling. After calling
      lowpan_invoke_rx_handlers we will do a kfree_skb and then NET_RX_DROP on
      error handling. We don't do this before, also on
      skb_share_check/skb_unshare which might manipulate the reference
      counters.

      After running some 'grep -r "dev_add_pack" net/' to look how others
      packet-layer receive callbacks works I detected that every subsystem do
      a kfree_skb, then NET_RX_DROP without calling skb functions which
      might manipulate the skb reference counters. This is the reason why we
      should do the same here like all others subsystems. I didn't find any
      documentation how the packet-layer receive callbacks handle NET_RX_DROP
      return values either.

      This patch will add a kfree_skb, then NET_RX_DROP handling for the
      "trivial checks", in case of skb_share_check/skb_unshare the kfree_skb
      call will be done inside these functions.

      Bluetooth: Fix crash in SMP when unpairing

      When unpairing the keys stored in hci_dev are removed. If SMP is
      ongoing the SMP context will also have references to these keys, so
      removing them from the hci_dev lists will make the pointers invalid.
      This can result in the following type of crashes:

      ipv6: gro: support sit protocol

      Tom Herbert added SIT support to GRO with commit
      19424e052fb4 ("sit: Add gro callbacks to sit_offload"),
      later reverted by Herbert Xu.

      The problem came because Tom patch was building GRO
      packets without proper meta data : If packets were locally
      delivered, we would not care.

      But if packets needed to be forwarded, GSO engine was not
      able to segment individual segments.

      With the following patch, we correctly set skb->encapsulation
      and inner network header. We also update gso_type.

      openvswitch: Serialize nested ct actions if provided

      If userspace provides a ct action with no nested mark or label, then the
      storage for these fields is zeroed. Later when actions are requested,
      such zeroed fields are serialized even though userspace didn't
      originally specify them. Fix the behaviour by ensuring that no action is
      serialized in this case, and reject actions where userspace attempts to
      set these fields with mask=0. This should make netlink marshalling
      consistent across deserialization/reserialization.

      openvswitch: Reject ct_state masks for unknown bits

      Currently, 0-bits are generated in ct_state where the bit position is
      undefined, and matches are accepted on these bit-positions. If userspace
      requests to match the 0-value for this bit then it may expect only a
      subset of traffic to match this value, whereas currently all packets
      will have this bit set to 0. Fix this by rejecting such masks.

      netlink: Rightsize IFLA_AF_SPEC size calculation

      if_nlmsg_size() overestimates the minimum allocation size of netlink
      dump request (when called from rtnl_calcit()) or the size of the
      message (when called from rtnl_getlink()). This is because
      ext_filter_mask is not supported by rtnl_link_get_af_size() and
      rtnl_link_get_size().

      The over-estimation is significant when at least one netdev has many
      VLANs configured (8 bytes for each configured VLAN).

      This patch-set "rightsizes" the protocol specific attribute size
      calculation by propagating ext_filter_mask to rtnl_link_get_af_size()
      and adding this a argument to get_link_af_size op in rtnl_af_ops.

      Bridge module already used filtering aware sizing for notifications.
      br_get_link_af_size_filtered() is consistent with the modified
      get_link_af_size op so it replaces br_get_link_af_size() in br_af_ops.
      br_get_link_af_size() becomes unused and thus removed.

      tipc: conditionally expand buffer headroom over udp tunnel

      In commit d999297c3dbbe ("tipc: reduce locking scope during packet 
reception")
      we altered the packet retransmission function. Since then, when
      restransmitting packets, we create a clone of the original buffer
      using __pskb_copy(skb, MIN_H_SIZE), where MIN_H_SIZE is the size of
      the area we want to have copied, but also the smallest possible TIPC
      packet size. The value of MIN_H_SIZE is 24.

      Unfortunately, __pskb_copy() also has the effect that the headroom
      of the cloned buffer takes the size MIN_H_SIZE. This is too small
      for carrying the packet over the UDP tunnel bearer, which requires
      a minimum headroom of 28 bytes. A change to just use pskb_copy()
      lets the clone inherit the original headroom of 80 bytes, but also
      assumes that the copied data area is of at least that size, something
      that is not always the case. So that is not a viable solution.

      We now fix this by adding a check for sufficient headroom in the
      transmit function of udp_media.c, and expanding it when necessary.

      tipc: allow non-linear first fragment buffer

      The current code for message reassembly is erroneously assuming that
      the the first arriving fragment buffer always is linear, and then goes
      ahead resetting the fragment list of that buffer in anticipation of
      more arriving fragments.

      However, if the buffer already happens to be non-linear, we will
      inadvertently drop the already attached fragment list, and later
      on trig a BUG() in __pskb_pull_tail().

      We see this happen when running fragmented TIPC multicast across UDP,
      something made possible since
      commit d0f91938bede ("tipc: add ip/udp media type")

      We fix this by not resetting the fragment list when the buffer is non-
      linear, and by initiatlizing our private fragment list tail pointer to
      the tail of the existing fragment list.

      openvswitch: Allocate memory for ovs internal device stats.

      "openvswitch: Remove vport stats" removed the per-vport statistics, in
      order to use the netdev's statistics fields.
      "openvswitch: Fix ovs_vport_get_stats()" fixed the export of these stats
      to user-space, by using the provided netdev_ops to collate them - but ovs
      internal devices still use an unallocated dev->tstats field to count
      packets, which are no longer exported by this api.

      Allocate the dev->tstats field for ovs internal devices, and wire up
      ndo_get_stats64 with the original implementation of
      ovs_vport_get_stats().

      On its own, "openvswitch: Fix ovs_vport_get_stats()" fixes the OOPs,
      unmasking a full-on panic on arm64:

      tipc: extend broadcast link window size

      The default fix broadcast window size is currently set to 20 packets.
      This is a very low value, set at a time when we were still testing on
      10 Mb/s hubs, and a change to it is long overdue.

      Commit 7845989cb4b3da1db ("net: tipc: fix stall during bclink wakeup 
procedure")
      revealed a problem with this low value. For messages of importance LOW,
      the backlog queue limit will be  calculated to 30 packets, while a
      single, maximum sized message of 66000 bytes, carried across a 1500 MTU
      network consists of 46 packets.

      This leads to the following scenario (among others leading to the same
      situation):

      1: Msg 1 of 46 packets is sent. 20 packets go to the transmit queue, 26
         packets to the backlog queue.
      2: Msg 2 of 46 packets is attempted sent, but rejected because there is
         no more space in the backlog queue at this level. The sender is added
         to the wakeup queue with a "pending packets chain size" number of 46.
      3: Some packets in the transmit queue are acked and released. We try to
         wake up the sender, but the pending size of 46 is bigger than the LOW
         wakeup limit of 30, so this doesn't happen.
      5: Subsequent acks releases all the remaining buffers. Each time we test
         for the wakeup criteria and find that 46 still is larger than 30,
         even after both the transmit and the backlog queues are empty.
      6: The sender is never woken up and given a chance to send its message.
         He is stuck.

      We could now loosen the wakeup criteria (used by link_prepare_wakeup())
      to become equal to the send criteria (used by tipc_link_xmit()), i.e.,
      by ignoring the "pending packets chain size" value altogether, or we can
      just increase the queue limits so that the criteria can be satisfied
      anyway. There are good reasons (potentially multiple waiting senders) to
      not opt for the former solution, so we choose the latter one.

      This commit fixes the problem by giving the broadcast link window a
      default value of 50 packets. We also introduce a new minimum link
      window size BCLINK_MIN_WIN of 32, which is enough to always avoid the
      described situation. Finally, in order to not break any existing users
      which may set the window explicitly, we enforce that the window is set
      to the new minimum value in case the user is trying to set it to
      anything lower.

      Just one fix from Ilia to resolve various issues that have resulted from
      buffer eviction.

        drm/nouveau/gem: return only valid domain when there's only one

      drm/nouveau/gem: return only valid domain when there's only one

      On nv50+, we restrict the valid domains to just the one where the buffer
      was originally created. However after the buffer is evicted to system
      memory, we might move it back to a different domain that was not
      originally valid. When sharing the buffer and retrieving its GEM_INFO
      data, we still want the domain that will be valid for this buffer in a
      pushbuf, not the one where it currently happens to be.

      This resolves fdo#92504 and several others. These are due to suspend
      evicting all buffers, making it more likely that they temporarily end up
      in the wrong place.

      drm: fix mutex leak in drm_dp_get_mst_branch_device

      In Linux 4.3-rc5, there is an error case in drm_dp_get_branch_device
      that returns without releasing mgr->lock, resulting a spew of kernel
      messages about a kernel work function possibly having leaked a mutex
      and presumably more serious adverse consequences later.  This patch
      changes the error to "goto out" to unlock the mutex before returning.

       "This contains a single fix, for when the IOMMU API is used to overlay
        an existing mapping comprised of 4KiB pages, with a mapping that can
        use superpages.

        For the *first* superpage in the new mapping, we were correctly¹
        freeing the old bottom-level page table page and clearing the link to
        it, before installing the superpage.  For subsequent superpages,
        however, we weren't.  This causes a memory leak, and a warning about
        setting a PTE which is already set.

        ¹ Well, not *entirely* correctly.  We just free the page table pages
          right there and then, which is wrong.  In fact they should only be
          freed *after* the IOTLB is flushed so we know the hardware will no
          longer be looking at them....  and in fact I note that the IOTLB
          flush is completely missing from the intel_iommu_map() code path,
          although it needs to be there if it's permitted to overwrite
          existing mappings.

          Fixing those is somewhat more intrusive though, and will probably
          need to wait for 4.4 at this point"

      could be either erased from the rb_tree twice or not erased at all.

      drm/vmwgfx: Stabilize the command buffer submission code

      This commit addresses some stability problems with the command buffer
      submission code recently introduced:

      1) Make the vmw_cmdbuf_man_process() function handle reruns internally to
      avoid losing interrupts if the caller forgets to rerun on -EAGAIN.
      2) Handle default command buffer allocations using inline command buffers.
      This avoids rare allocation deadlocks.
      3) In case of command buffer errors we might lose fence submissions.
      Therefore send a new fence after each command buffer error. This will help
      avoid lengthy fence waits.

      net: mv643xx_eth: TSO TX data corruption fixes

      as previously discussed [1] the mv643xx_eth driver has some
      issues with data corruption when using TCP segmentation offload (TSO).

      The following patch set improves this situation by fixing two data
      corruption bugs in the TSO TX path.

      Before applying the patches repeatedly accessing large files located on
      a SMB share on my NSA325 NAS with TSO enabled resulted in different
      hash sums, which confirmed that data corruption is happening during
      file transfer. After applying the patches the hash sums were the same.

      As this is my first patch submission please feel free to point out any
      issues with the patch set.

      To prevent a race between the TX DMA engine and the CPU the writing of the
      first transmit descriptor must be deferred until all following descriptors
      have been updated. The network card may otherwise start transmitting 
before
      all packet descriptors are set up correctly, which leads to data 
corruption
      or an aborted transmit operation.

      This deferral is already done in the non-TSO TX path, implement it also in
      the TSO TX path.

      net: mv643xx_eth: Ensure proper data alignment in TSO TX path

      The TX DMA engine requires that buffers with a size of 8 bytes or smaller
      must be 64 bit aligned. This requirement may be violated when doing TSO,
      as in this case larger skb frags can be broken up and transmitted in small
      parts with then inappropriate alignment.

      Fix this by checking for proper alignment before handing a buffer to the
      DMA engine. If the data is misaligned realign it by copying it into the
      TSO header data area.

      arm64: Delay cpu feature capability checks

      At the moment we run through the arm64_features capability list for
      each CPU and set the capability if one of the CPU supports it. This
      could be problematic in a heterogeneous system with differing 
capabilities.
      Delay the CPU feature checks until all the enabled CPUs are up(i.e,
      smp_cpus_done(), so that we can make better decisions based on the
      overall system capability. Once we decide and advertise the capabilities
      the alternatives can be applied. From this state, we cannot roll back
      a feature to disabled based on the values from a new hotplugged CPU,
      due to the runtime patching and other reasons. So, for all new CPUs,
      we need to make sure that they have the established system capabilities.
      Failing which, we bring the CPU down, preventing it from turning online.
      Once the capabilities are decided, any new CPU booting up goes through
      verification to ensure that it has all the enabled capabilities and also
      invokes the respective enable() method on the CPU.

      The CPU errata checks are not delayed and is still executed per-CPU
      to detect the respective capabilities. If we ever come across a non-errata
      capability that needs to be checked on each-CPU, we could introduce them 
via
      a new capability table(or introduce a flag), which can be processed per 
CPU.

      The next patch will make the feature checks use the system wide
      safe value of a feature register.

      NOTE: The enable() methods associated with the capability is scheduled
      on all the CPUs (which is the only use case at the moment). If we need
      a different type of 'enable()' which only needs to be run once on any CPU,
      we should be able to handle that when needed.

      arm64: Keep track of CPU feature registers

      This patch adds an infrastructure to keep track of the CPU feature
      registers on the system. For each register, the infrastructure keeps
      track of the system wide safe value of the feature bits. Also, tracks
      the which fields of a register should be matched strictly across all
      the CPUs on the system for the SANITY check infrastructure.

      The feature bits are classified into following 3 types depending on
      the implication of the possible values. This information is used to
      decide the safe value for a feature.

      LOWER_SAFE  - The smaller value is safer
      HIGHER_SAFE - The bigger value is safer
      EXACT       - We can't decide between the two, so a predefined safe_value 
is used.

      This infrastructure will be later used to make better decisions for:

       - Kernel features (e.g, KVM, Debug)
       - SANITY Check
       - CPU capability
       - ELF HWCAP
       - Exposing CPU Feature register to userspace.

      Merge branch 'tcp-rack'

      Yuchung Cheng says:

      ====================
      RACK loss detection

      RACK (Recent ACK) loss recovery uses the notion of time instead of
      packet sequence (FACK) or counts (dupthresh).

      It's inspired by the FACK heuristic in tcp_mark_lost_retrans(): when a
      limited transmit (new data packet) is sacked in recovery, then any
      retransmission sent before that newly sacked packet was sent must have
      been lost, since at least one round trip time has elapsed.

      But that existing heuristic from tcp_mark_lost_retrans()
      has several limitations:
        1) it can't detect tail drops since it depends on limited transmit
        2) it's disabled upon reordering (assumes no reordering)
        3) it's only enabled in fast recovery but not timeout recovery

      RACK addresses these limitations with a core idea: an unacknowledged
      packet P1 is deemed lost if a packet P2 that was sent later is is
      s/acked, since at least one round trip has passed.

      Since RACK cares about the time sequence instead of the data sequence
      of packets, it can detect tail drops when a later retransmission is
      s/acked, while FACK or dupthresh can't. For reordering RACK uses a
      dynamically adjusted reordering window ("reo_wnd") to reduce false
      positives on ever (small) degree of reordering, similar to the delayed
      Early Retransmit.

      In the current patch set RACK is only a supplemental loss detection
      and does not trigger fast recovery. However we are developing RACK
      to replace or consolidate FACK/dupthresh, early retransmit, and
      thin-dupack. These heuristics all implicitly bear the time notion.
      For example, the delayed Early Retransmit is simply applying RACK
      to trigger the fast recovery with small inflight.

      RACK requires measuring the minimum RTT. Tracking a global min is less
      robust due to traffic engineering pathing changes. Therefore it uses a
      windowed filter by Kathleen Nichols. The min RTT can also be useful
      for various other purposes like congestion control or stat monitoring.

      This patch has been used on Google servers for well over 1 year. RACK
      has also been implemented in the QUIC protocol. We are submitting an
      IETF draft as well.

      tcp: use RACK to detect losses

      This patch implements the second half of RACK that uses the the most
      recent transmit time among all delivered packets to detect losses.

      tcp_rack_mark_lost() is called upon receiving a dubious ACK.
      It then checks if an not-yet-sacked packet was sent at least
      "reo_wnd" prior to the sent time of the most recently delivered.
      If so the packet is deemed lost.

      The "reo_wnd" reordering window starts with 1msec for fast loss
      detection and changes to min-RTT/4 when reordering is observed.
      We found 1msec accommodates well on tiny degree of reordering
      (<3 pkts) on faster links. We use min-RTT instead of SRTT because
      reordering is more of a path property but SRTT can be inflated by
      self-inflicated congestion. The factor of 4 is borrowed from the
      delayed early retransmit and seems to work reasonably well.

      Since RACK is still experimental, it is now used as a supplemental
      loss detection on top of existing algorithms. It is only effective
      after the fast recovery starts or after the timeout occurs. The
      fast recovery is still triggered by FACK and/or dupack threshold
      instead of RACK.

      We introduce a new sysctl net.ipv4.tcp_recovery for future
      experiments of loss recoveries. For now RACK can be disabled by
      setting it to 0.

      tcp: track the packet timings in RACK

      This patch is the first half of the RACK loss recovery.

      RACK loss recovery uses the notion of time instead
      of packet sequence (FACK) or counts (dupthresh). It's inspired by the
      previous FACK heuristic in tcp_mark_lost_retrans(): when a limited
      transmit (new data packet) is sacked, then current retransmitted
      sequence below the newly sacked sequence must been lost,
      since at least one round trip time has elapsed.

      But it has several limitations:
      1) can't detect tail drops since it depends on limited transmit
      2) is disabled upon reordering (assumes no reordering)
      3) only enabled in fast recovery ut not timeout recovery

      RACK (Recently ACK) addresses these limitations with the notion
      of time instead: a packet P1 is lost if a later packet P2 is s/acked,
      as at least one round trip has passed.

      Since RACK cares about the time sequence instead of the data sequence
      of packets, it can detect tail drops when later retransmission is
      s/acked while FACK or dupthresh can't. For reordering RACK uses a
      dynamically adjusted reordering window ("reo_wnd") to reduce false
      positives on ever (small) degree of reordering.

      This patch implements tcp_advanced_rack() which tracks the
      most recent transmission time among the packets that have been
      delivered (ACKed or SACKed) in tp->rack.mstamp. This timestamp
      is the key to determine which packet has been lost.

      Consider an example that the sender sends six packets:
      T1: P1 (lost)
      T2: P2
      T3: P3
      T4: P4
      T100: sack of P2. rack.mstamp = T2
      T101: retransmit P1
      T102: sack of P2,P3,P4. rack.mstamp = T4
      T205: ACK of P4 since the hole is repaired. rack.mstamp = T101

      We need to be careful about spurious retransmission because it may
      falsely advance tp->rack.mstamp by an RTT or an RTO, causing RACK
      to falsely mark all packets lost, just like a spurious timeout.

      We identify spurious retransmission by the ACK's TS echo value.
      If TS option is not applicable but the retransmission is acknowledged
      less than min-RTT ago, it is likely to be spurious. We refrain from
      using the transmission time of these spurious retransmissions.

      The second half is implemented in the next patch that marks packet
      lost using RACK timestamp.

      tcp: track min RTT using windowed min-filter

      Kathleen Nichols' algorithm for tracking the minimum RTT of a
      data stream over some measurement window. It uses constant space
      and constant time per update. Yet it almost always delivers
      the same minimum as an implementation that has to keep all
      the data in the window. The measurement window is tunable via
      sysctl.net.ipv4.tcp_min_rtt_wlen with a default value of 5 minutes.

      The algorithm keeps track of the best, 2nd best & 3rd best min
      values, maintaining an invariant that the measurement time of
      the n'th best >= n-1'th best. It also makes sure that the three
      values are widely separated in the time window since that bounds
      the worse case error when that data is monotonically increasing
      over the window.

      Upon getting a new min, we can forget everything earlier because
      it has no value - the new min is less than everything else in the
      window by definition and it's the most recent. So we restart fresh
      on every new min and overwrites the 2nd & 3rd choices. The same
      property holds for the 2nd & 3rd best.

      Therefore we have to maintain two invariants to maximize the
      information in the samples, one on values (1st.v <= 2nd.v <=
      3rd.v) and the other on times (now-win <=1st.t <= 2nd.t <= 3rd.t <=
      now). These invariants determine the structure of the code

      The RTT input to the windowed filter is the minimum RTT measured
      from ACK or SACK, or as the last resort from TCP timestamps.

      The accessor tcp_min_rtt() returns the minimum RTT seen in the
      window. ~0U indicates it is not available. The minimum is 1usec
      even if the true RTT is below that.

      net, phy, smsc: add posibility to disable energy detect mode

      On some boards the energy enable detect mode leads in
      trouble with some switches, so make the enabling of
      this mode configurable through DT.
      Therefore the property "smsc,disable-energy-detect" is
      introduced.

      Patch 1 introduces phy-handle support for the ti,cpsw
      driver. This is needed now for the smsc phy.

      Patch 2 adds the disable energy mode functionality
      to the smsc phy

      Changes in v2:
      - add comments from Florian Fainelli
        - I did not change disable property name into enable
          because I fear to break existing behaviour
        - add smsc vendor prefix
        - remove CONFIG_OF and use __maybe_unused
        - introduce "phy-handle" ability into ti,cpsw
          driver, so I can remove bogus:
            if (!of_node && dev->parent->of_node)
                of_node = dev->parent->of_node;
          construct. Therefore new patch for the ti,cpsw
          driver is necessary.

      Bluetooth: Fix missing hdev locking for LE scan cleanup

      The hci_conn objects don't have a dedicated lock themselves but rely
      on the caller to hold the hci_dev lock for most types of access. The
      hci_conn_timeout() function has so far sent certain HCI commands based
      on the hci_conn state which has been possible without holding the
      hci_dev lock.

      The recent changes to do LE scanning before connect attempts added
      even more operations to hci_conn and hci_dev from hci_conn_timeout,
      thereby exposing potential race conditions with the hci_dev and
      hci_conn states.

      As an example of such a race, here there's a timeout but an
      l2cap_sock_connect() call manages to race with the cleanup routine:

      [  +0.000003] hci_conn_hold: hcon f53d56e0 orig refcnt 0

      Above the l2cap_chan_connect() shouldn't have been able to reach the
      hci_conn f53d56e0 anymore but since hci_conn_timeout didn't do proper
      locking that's not the case. The end result is a reference to hci_conn
      that's not in the conn_hash list, resulting in list corruption when
      trying to remove it later:

      The necessary fix is unfortunately more complicated than just adding
      hci_dev_lock/unlock calls to the hci_conn_timeout() call path.
      Particularly, the hci_conn_del() API, which expects the hci_dev lock to
      be held, performs a cancel_delayed_work_sync(&hcon->disc_work) which
      would lead to a deadlock if the hci_conn_timeout() call path tries to
      acquire the same lock.

      This patch solves the problem by deferring the cleanup work to a
      separate work callback. To protect against the hci_dev or hci_conn
      going away meanwhile temporary references are taken with the help of
      hci_dev_hold() and hci_conn_get().

      powerpc/powernv: Handle irq_happened flag correctly in off-line loop

      This fixes a bug where it is possible for an off-line CPU to fail to go
      into a low-power state (nap/sleep/winkle), and to become unresponsive to
      requests from the KVM subsystem to wake up and run a VCPU. What can
      happen is that a maskable interrupt of some kind (external, decrementer,
      hypervisor doorbell, or HMI) after we have called local_irq_disable() at
      the beginning of pnv_smp_cpu_kill_self() and before interrupts are
      hard-disabled inside power7_nap/sleep/winkle(). In this situation, the
      pending event is marked in the irq_happened flag in the PACA. This
      pending event prevents power7_nap/sleep/winkle from going to the
      requested low-power state; instead they return immediately. We don't
      deal with any of these pending event flags in the off-line loop in
      pnv_smp_cpu_kill_self() because power7_nap et al. return 0 in this case,
      so we will have srr1 == 0, and none of the processing to clear
      interrupts or doorbells will be done.

      Usually, the most obvious symptom of this is that a KVM guest will fail
      with a console message saying "KVM: couldn't grab cpu N".

      This fixes the problem by making sure we handle the irq_happened flags
      properly. First, we hard-disable before the off-line loop. Once we have
      hard-disabled, the irq_happened flags can't change underneath us. We
      unconditionally clear the DEC and HMI flags: there is no processing of
      timer interrupts while off-line, and the necessary HMI processing is all
      done in lower-level code. We leave the EE and DBELL flags alone for the
      first iteration of the loop, so that we won't fail to respond to a
      split-core request that came in just before hard-disabling. Within the
      loop, we handle external interrupts if the EE bit is set in irq_happened
      as well as if the low-power state was interrupted by an external
      interrupt. (We don't need to do the msgclr for a pending doorbell in
      irq_happened, because doorbells are edge-triggered and don't remain
      pending in hardware.) Then we clear both the EE and DBELL flags, and
      once clear, they cannot be set again (until this CPU comes online again,
      that is).

      This also fixes the debug check to not be done when we just ran a KVM

      irq_happened.

      powerpc: Revert "Use the POWER8 Micro Partition Prefetch Engine in KVM HV 
on POWER8"

      This reverts commit 9678cdaae939 ("Use the POWER8 Micro Partition
      Prefetch Engine in KVM HV on POWER8") because the original commit had
      multiple, partly self-cancelling bugs, that could cause occasional
      memory corruption.

      In fact the logmpp instruction was incorrectly using register r0 as the
      source of the buffer address and operation code, and depending on what
      was in r0, it would either do nothing or corrupt the 64k page pointed to
      by r0.

      The logmpp instruction encoding and the operation code definitions could
      be corrected, but then there is the problem that there is no clearly
      defined way to know when the hardware has finished writing to the
      buffer.

      The original commit attempted to work around this by aborting the
      write-out before starting the prefetch, but this is ineffective in the
      case where the virtual core is now executing on a different physical
      core from the one where the write-out was initiated.

      These problems plus advice from the hardware designers not to use the
      function (since the measured performance improvement from using the
      feature was actually mostly negative), mean that reverting the code is
      the best option.

KVM HV on POWER8")

      iommu/amd: Don't clear DTE flags when modifying it

      During device assignment/deassignment the flags in the DTE
      get lost, which might cause spurious faults, for example
      when the device tries to access the system management range.
      Fix this by not clearing the flags with the rest of the DTE.

      x86/microcode: Unmodularize the microcode driver

      Make CONFIG_MICROCODE a bool. It was practically a bool already anyway,
      since early loader was forcing it to =y.

      Regardless, there's no real reason to have something be a module which
      gets built-in on the majority of installations out there. And its not
      like there's noticeable change in functionality - we still can load late
      microcode - just the module glue disappears.

      x86/mce: Fix thermal throttling reporting after kexec

      The per CPU thermal vector init code checks if the thermal
      vector is already installed and complains and bails out if it
      is.

      This happens after kexec, as kernel shut down does not clear the
      thermal vector APIC register.

      This causes two problems:

      1. So we always do not fully initialize thermal reports after
         kexec. The CPU is still likely initialized, as the previous
         kernel should have done it. But we don't set up the software
         pointer to the thermal vector, so reporting may end up with a
         unknown thermal interrupt message.

      2. Also it complains for every logical CPU, even though the
         value is actually derived from BP only.

      The problem is that we end up with one message per CPU, so on
      larger systems it becomes very noisy and messes up the otherwise
      nicely formatted CPU bootup numbers in the kernel log.

      Just remove the check. I checked the code and there's no valid
      code paths where the thermal init code for a CPU could be called
      multiple times.

      Why the kernel does not clean up this value on shutdown:

      The thermal monitoring is controlled per logical CPU thread.
      Normal shutdown code is just running on one CPU. To disable it
      we would need a broadcast NMI to all CPUs on shut down. That's
      overkill for this. So we just ignore it after kexec.

      x86/amd_nb, EDAC: Rename amd_get_node_id()

      This function doesn't give us the "Node ID" as the function name
      suggests. Rather, it receives a PCI device as argument, checks
      the available F3 PCI device IDs in the system and returns the
      index of the matching Bus/Device IDs.

      Rename it to amd_pci_dev_to_node_id().

      No functional change is introduced.

      x86/setup: Do not reserve crashkernel high memory if low reservation 
failed

      People reported that when allocating crashkernel memory using
      the ",high" and ",low" syntax, there were cases where the
      reservation of the high portion succeeds but the reservation of
      the low portion fails.

      Then kexec can load the kdump kernel successfully, but booting
      the kdump kernel fails as there's no low memory.

      The low memory allocation for the kdump kernel can fail on large
      systems for a couple of reasons. For example, the manually
      specified crashkernel low memory can be too large and thus no
      adequate memblock region would be found.

      Therefore, we try to reserve low memory for the crash kernel
      *after* the high memory portion has been allocated. If that
      fails, we free crashkernel high memory too and return. The user
      can then take measures accordingly.

      mmc: core: Fix init_card in 52Mhz

      Suppose that we got a data crc error, and it triggers the mmc_reset.
      mmc_reset will call mmc_send_status to see if HW reset was supported.
      before issue CMD13, it will do retune, and if EMMC was in HS400 mode,
      it will reduce frequency to 52Mhz firstly, then results in card init
      was doing at 52Mhz.
      The mmc_send_status was originally only done for mmc_test, should drop
      it. And, rename the "eMMC hardware reset" to "Reset test", as we would
      also be able to use the test for SD-cards.

      mac80211: move station statistics into sub-structs

      Group station statistics by where they're (mostly) updated
      (TX, RX and TX-status) and group them into sub-structs of
      the struct sta_info.

      Also rename the variables since the grouping now makes it
      obvious where they belong.

      This makes it easier to identify where the statistics are
      updated in the code, and thus easier to think about them.

      New driver: rtl8xxxu (mac80211)

      This is an alternate driver for a number of Realtek WiFi USB devices,
      including RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU.
      It was written from scratch utilizing the Linux mac80211 stack.

      After spending months cleaning up the vendor provided rtl8723au
      driver, which comes with it's own 802.11 stack included, I decided to
      rewrite this driver from the bottom up.

      Many thanks to Johannes Berg for 802.11 insights and help and Larry
      Finger for help with the vendor driver.

      The full git log for the development of this driver can be found here:
      git git://git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git
          branch rtl8723au-mac80211

      This driver is still under development, but has proven to be very
      stable for me. It currently supports station mode only. It has support
      for OFDM and CCK rates. It does lack certain features found in the
      staging driver, such as power management, AMPDU, and 40MHz channel
      support. In addition it does not support AD-HOC, AP, and monitor mode
      support at this point.

      The driver is known to work with the following devices:
      Lenovo Yoga (rtl8723au)
      TP-Link TL-WN823N (rtl8192cu)
      Etekcity 6R (rtl8188cu)
      Daffodil LAN03 (rtl8188cu)

      For example, the file extent layout is like:
      0 4K      8K      16K     32K
      |<-----Extent A---------------->|
      |<--Inode size: 18K---------->|

      But if calling fallocate even for range [0,4K), it will cause btrfs to
      re-truncate the range [16,32K), causing COW and a new extent.

      0 4K      8K      16K     32K
      |///////| <- Fallocate call range
      |<-----Extent A-------->|<--B-->|

      The cause is quite easy, just a careless btrfs_truncate_inode() in a
      else branch without extra judgment.
      Fix it by add judgment on whether the fallocate range is beyond isize.

      tracing: Do not allow stack_tracer to record stack in NMI

      The code in stack tracer should not be executed within an NMI as it grabs
      spinlocks and stack tracing an NMI gives the possibility of causing a
      deadlock. Although this is safe on x86_64, because it does not perform 
stack
      traces when the task struct stack is not in use (interrupts and NMIs), it
      may be an issue for NMIs on i386 and other archs that use the same stack 
as
      the NMI.

      Bluetooth: l2cap_disconnection_req priority over shutdown

      There is a L2CAP protocol race between the local peer and
      the remote peer demanding disconnection of the L2CAP link.

      When L2CAP ERTM is used, l2cap_sock_shutdown() can be called
      from userland to disconnect L2CAP. However, there can be a
      delay introduced by waiting for ACKs. During this waiting
      period, the remote peer may have sent a Disconnection Request.
      Therefore, recheck the shutdown status of the socket
      after waiting for ACKs because there is no need to do
      further processing if the connection has gone.

      Bluetooth: Reorganize mutex lock in l2cap_sock_shutdown()

      This commit reorganizes the mutex lock and is now
      only protecting l2cap_chan_close(). This is now consistent
      with other places where l2cap_chan_close() is called.

      If a conn connection exists, call
      mutex_lock(&conn->chan_lock) before calling l2cap_chan_close()
      to ensure other L2CAP protocol operations do not interfere.

      Note that the conn structure has to be protected from being
      freed as it is possible for the connection to be disconnected
      whilst the locks are not held. This solution allows the mutex
      lock to be used even when the connection has just been
      disconnected.

      This commit also reduces the scope of chan locking.

      The only place where chan locking is needed is the call to
      l2cap_chan_close(chan, 0) which if necessary closes the channel.
      Therefore, move the l2cap_chan_lock(chan) and
      l2cap_chan_lock(chan) locking calls to around
      l2cap_chan_close(chan, 0).

      This allows __l2cap_wait_ack(sk, chan) to be called with no
      chan locks being held so L2CAP messaging over the ACL link
      can be done unimpaired.

      Bluetooth: Unwind l2cap_sock_shutdown()

      l2cap_sock_shutdown() is designed to only action shutdown
      of the channel when shutdown is not already in progress.
      Therefore, reorganise the code flow by adding a goto
      to jump to the end of function handling when shutdown is
      already being actioned. This removes one level of code
      indentation and make the code more readable.

      6lowpan: rework tc and flow label handling

      This patch reworks the handling of compression/decompression of traffic
      class and flow label handling. The current method is hard to understand,
      also doesn't checks if we can read the buffer from skb length.

      I tried to put the shifting operations into static inline functions and
      comment each steps which I did there to make it hopefully somewhat more
      readable. The big mess to deal with that is the that the ipv6 header
      bring the order "DSCP + ECN" but iphc uses "ECN + DSCP". Additional the
      DCSP + ECN bits are splitted in ipv6_hdr inside the priority and
      flow_lbl[0] fields.

      I tested these compressions by using fakelb 802.15.4 driver and
      manipulate the tc and flow label fields manually in function
      "__ip6_local_out" before the skb will be send to lower layers. Then I
      looked up the tc and flow label fields in wireshark on a wpan and lowpan
      interface.

      6lowpan: cleanup lowpan_header_decompress

      This patch changes the lowpan_header_decompress function by removing
      inklayer related information from parameters. This is currently for
      supporting short and extended address for iphc handling in 802154.
      We don't support short address handling anyway right now, but there
      exists already code for handling short addresses in
      lowpan_header_decompress.

      The address parameters are also changed to a void pointer, so 6LoWPAN
      linklayer specific code can put complex structures as these parameters
      and cast it again inside the generic code by evaluating linklayer type
      before. The order is also changed by destination address at first and
      then source address, which is the same like all others functions where
      destination is always the first, memcpy, dev_hard_header,
      lowpan_header_compress, etc.

      This patch also moves the fetching of iphc values from 6LoWPAN linklayer
      specific code into the generic branch.

      Bluetooth: Fix removing connection parameters when unpairing

      The commit 89cbb0638e9b7 introduced support for deferred connection
      parameter removal when unpairing by removing them only once an
      existing connection gets disconnected. However, it failed to address
      the scenario when we're *not* connected and do an unpair operation.

      What makes things worse is that most user space BlueZ versions will
      first issue a disconnect request and only then unpair, meaning the
      buggy code will be triggered every time. This effectively causes the
      kernel to resume scanning and reconnect to a device for which we've
      removed all keys and GATT database information.

      This patch fixes the issue by adding the missing call to the
      hci_conn_params_del() function to a branch which handles the case of
      no existing connection.

      The general layout of Bluetooth devices is that interface 0 is the main
      interface and interface 1 is for audio data. This design obviously moves
      it to main interface 2 and audio data on interface 3.

      Starting with the MacBookPro12,1 (early 2015 models) the new Broadcom
      BCM943602CS cards are used which show this interface layout.

      Bluetooth: btusb: Add support for Foxconn/Lenovo BCM43142A0 (105b:e065)

      Recently salvaged this 'BCM43142A0' WiFi/Bluetooth module from a Lenovo

      and noticed it doesn't work automatically, because the USB IDs are missing
      from btusb.c.

      Plugging in the adapter on Linux 4.1 (dmesg):

      Support for the chipset was added in commit 88f9b65 and a similar BCM43142
      based device was added in commit 8f0c304.

      To work around the issue, I got the firmware
      (BCM43142A0_001.001.011.0122.0153) off a Windows installation of Broadcom
      bluetooth driver and converted it to a .hcd -file via. hex2hcd and placed 
it
      in /lib/firmware/brcm/BCM.hcd. After that:

      $ echo "105b e065 0 19ff 0239" > /sys/bus/usb/drivers/btusb/new_id
      ...(plug in the adapter)

      Bam, now it works for me!

      Bluetooth: hidp: fix device disconnect on idle timeout

      The HIDP specs define an idle-timeout which automatically disconnects a
      device. This has always been implemented in the HIDP layer and forced a
      synchronous shutdown of the hidp-scheduler. This works just fine, but
      lacks a forced disconnect on the underlying l2cap channels. This has been
      broken since:

          commit 5205185d461d5902325e457ca80bd421127b7308

              Bluetooth: hidp: remove old session-management

      The old session-management always forced an l2cap error on the ctrl/intr
      channels when shutting down. The new session-management skips this, as we
      don't want to enforce channel policy on the caller. In other words, if
      user-space removes an HIDP device, the underlying channels (which are
      *owned* and *referenced* by user-space) are still left active. User-space
      needs to call shutdown(2) or close(2) to release them.

      Unfortunately, this does not work with idle-timeouts. There is no way to
      signal user-space that the HIDP layer has been stopped. The API simply
      does not support any event-passing except for poll(2). Hence, we restore
      old behavior and force EUNATCH on the sockets if the HIDP layer is
      disconnected due to idle-timeouts (behavior of explicit disconnects
      remains unmodified). User-space can still call

          getsockopt(..., SO_ERROR, ...)

      ..to retrieve the EUNATCH error and clear sk_err. Hence, the channels can
      still be re-used (which nobody does so far, though). Therefore, the API
      still supports the new behavior, but with this patch it's also compatible
      to the old implicit channel shutdown.

      Bluetooth: Add new quirk for non-persistent diagnostic settings

      If the diagnostic settings are not persistent over HCI Reset, then this
      quirk can be used to tell the Bluetoth core about it. This will ensure
      that the settings are programmed correctly when the controller is
      powered up.

      Bluetooth: bpa10x: fix BT_HCIUART dependency

      The change to bpa10x to use the h4_recv_buf helper added a dependency
      on BT_HCIUART. This was incorrectly added to Kconfig by adding a
      'select' statement, which now in turn causes build failures
      when CONFIG_TTY is not set:

      warning: (BT_HCIBPA10X) selects BT_HCIUART which has unmet direct 
dependencies (NET && BT && TTY)
      vers/built-in.o: In function `hci_uart_tty_receive':
      fpga-mgr.c:(.text+0x282824): undefined reference to `tty_unthrottle'
      drivers/built-in.o: In function `hci_uart_tty_ioctl':
      fpga-mgr.c:(.text+0x282aa0): undefined reference to `n_tty_ioctl_helper'
      drivers/built-in.o: In function `hci_uart_flush':

      This replaces the 'select BT_HCIUART' dependency with 'depends on', which
      does not have this kind of problem. Alternatively, one could add 'depends
      on TTY', but avoiding 'select' on user-visible options is generally the
      preferred choice as that does not introduce the potential for dependency
      loops or incomplete dependency chains.

      Bluetooth: Don't use remote address type to decide IRK persistency

      There are LE devices on the market that start off by announcing their
      public address and then once paired switch to using private address.
      To be interoperable with such devices we should simply trust the fact
      that we're receiving an IRK from them to indicate that they may use
      private addresses in the future. Instead, simply tie the persistency
      to the bonding/no-bonding information the same way as for LTKs and
      CSRKs.

      Bluetooth: Queue diagnostic messages together with HCI packets

      Sending diagnostic messages directly to the monitor socket might cause

      instead of trying to directly forward them, queue them up with the other
      HCI packets and lets them be processed by the sockets at the same time.

      perf cpu_map: Fix core dump caused by per-socket/core system-wide stat

      Perf will core dump if --per-socket/core -a are applied for perf stat.

      The root cause is that cpu_map__build_map set refcnt of evlist's cpu_map
      to 1.  It should set refcnt for the newly created cpu_map, not evlist's
      cpu_map.

      Here is the example:

        # perf stat -e cycles --per-socket -a sleep 1

         Performance counter stats for 'system wide':

        S0       36         30,196,257      cycles

      IB/cma: Use inner P_Key to determine netdev

      When discussing the patches to demux ids in rdma_cm instead of ib_cm, it
      was decided that it is best to use the P_Key value in the packet headers.
      However, the mlx5 and ipath drivers are currently unable to send correct
      P_Key values in GMP headers. They always send using a single P_Key that is
      set during the GSI QP initialization.

      Change the rdma_cm code to look at the P_Key value that is part of the
      packet payload as a workaround. Once the drivers are fixed this patch can
      be reverted.

      arm/arm64: KVM: Fix disabled distributor operation

      We currently do a single update of the vgic state when the distributor
      enable/disable control register is accessed and then bypass updating the
      state for as long as the distributor remains disabled.

      This is incorrect, because updating the state does not consider the
      distributor enable bit, and this you can end up in a situation where an
      interrupt is marked as pending on the CPU interface, but not pending on
      the distributor, which is an impossible state to be in, and triggers a
      warning.  Consider for example the following sequence of events:

      1. An interrupt is marked as pending on the distributor
         - the interrupt is also forwarded to the CPU interface
      2. The guest turns off the distributor (it's about to do a reboot)
         - we stop updating the CPU interface state from now on
      3. The guest disables the pending interrupt
         - we remove the pending state from the distributor, but don't touch
           the CPU interface, see point 2.

      Since the distributor disable bit really means that no interrupts should
      be forwarded to the CPU interface, we modify the code to keep updating
      the internal VGIC state, but always set the CPU interface pending bits
      to zero when the distributor is disabled.

      arm/arm64: KVM: Clear map->active on pend/active clear

      When a guest reboots or offlines/onlines CPUs, it is not uncommon for it
      to clear the pending and active states of an interrupt through the
      emulated VGIC distributor.  However, since the architected timers are
      defined by the architecture to be level triggered and the guest
      rightfully expects them to be that, but we emulate them as
      edge-triggered, we have to mimic level-triggered behavior for an
      edge-triggered virtual implementation.

      We currently do not signal the VGIC when the map->active field is true,
      because it indicates that the guest has already been signalled of the
      interrupt as required.  Normally this field is set to false when the
      guest deactivates the virtual interrupt through the sync path.

      We also need to catch the case where the guest deactivates the interrupt
      through the emulated distributor, again allowing guests to boot even if
      the original virtual timer signal hit before the guest's GIC
      initialization sequence is run.

      arm/arm64: KVM: Fix arch timer behavior for disabled interrupts

      We have an interesting issue when the guest disables the timer interrupt
      on the VGIC, which happens when turning VCPUs off using PSCI, for
      example.

      The problem is that because the guest disables the virtual interrupt at
      the VGIC level, we never inject interrupts to the guest and therefore
      never mark the interrupt as active on the physical distributor.  The
      host also never takes the timer interrupt (we only use the timer device
      to trigger a guest exit and everything else is done in software), so the
      interrupt does not become active through normal means.

      The result is that we keep entering the guest with a programmed timer
      that will always fire as soon as we context switch the hardware timer
      state and run the guest, preventing forward progress for the VCPU.

      Since the active state on the physical distributor is really part of the
      timer logic, it is the job of our virtual arch timer driver to manage
      this state.

      The timer->map->active boolean field indicates whether we have signalled
      this interrupt to the vgic and if that interrupt is still pending or
      active.  As long as that is the case, the hardware doesn't have to
      generate physical interrupts and therefore we mark the interrupt as
      active on the physical distributor.

      We also have to restore the pending state of an interrupt that was
      queued to an LR but was retired from the LR for some reason, while
      remaining pending in the LR.

      KVM: arm: use GIC support unconditionally

      The vgic code on ARM is built for all configurations that enable KVM,
      but the parent_data field that it references is only present when
      CONFIG_IRQ_DOMAIN_HIERARCHY is set:

      virt/kvm/arm/vgic.c: In function 'kvm_vgic_map_phys_irq':
      virt/kvm/arm/vgic.c:1781:13: error: 'struct irq_data' has no member named 
'parent_data'

      This flag is implied by the GIC driver, and indeed the VGIC code only
      makes sense if a GIC is present. This changes the CONFIG_KVM symbol
      to always select GIC, which avoids the issue.

      KVM: arm/arm64: Do not inject spurious interrupts

      When lowering a level-triggered line from userspace, we forgot to lower
      the pending bit on the emulated CPU interface and we also did not
      re-compute the pending_on_cpu bitmap for the CPU affected by the change.

      Update vgic_update_irq_pending() to fix the two issues above and also
      raise a warning in vgic_quue_irq_to_lr if we encounter an interrupt
      pending on a CPU which is neither marked active nor pending.

      tracing: Have stack tracer force RCU to be watching

      The stack tracer was triggering the WARN_ON() in module.c:

       static void module_assert_mutex_or_preempt(void)
       {
       #ifdef CONFIG_LOCKDEP
        if (unlikely(!debug_locks))
                return;

        WARN_ON(!rcu_read_lock_sched_held() &&
                !lockdep_is_held(&module_mutex));
       #endif
       }

      The reason is that the stack tracer traces all function calls, and some of
      those calls happen while exiting or entering user space and idle. Some of
      these functions are called after RCU had already stopped watching, as RCU
      does not watch userspace or idle CPUs.

      If a max stack is hit, then the save_stack_trace() is called, which will
      check module addresses and call module_assert_mutex_or_preempt(), and then
      trigger the warning. Sad part is, the warning itself will also do a stack
      trace and tigger the same warning. That probably should be fixed.

      The warning was added by 0be964be0d45 "module: Sanitize RCU usage and
      locking" but this bug has probably been around longer. But it's unlikely 
to
      cause much harm, but the new warning causes the system to lock up.

      sg@892: ed03d938: 00000000 3cde2a40 00000028 00000000
      sg@892: ed03d948: 00000000 3d03d100 00000006 00000000
      sg@892: ed03d958: 00000000 7e8aa700 40000020 00000000

      0x68 comes from 0x28 (the context size) plus the "in_len" rounded down
      to a block size (0x40).  in_len comes from 0x26 bytes of unhashed data
      from the previous operation, plus the 0x20 bytes from the latest
      operation.

      The fixed version would create:

      sg@892: ed03d938: 00000000 3cde2a40 00000028 00000000
      sg@892: ed03d948: 00000000 3d03d100 00000026 00000000
      sg@892: ed03d958: 00000000 7e8aa700 40000020 00000000

      which replaces the 0x06 length with the correct 0x26 bytes of previously
      unhashed data.

      This fixes a previous commit which erroneously "fixed" this due to a
      DMA-API bug report; that commit indicates that the bug was caused via a
      test_ahash_pnum() function in the tcrypt module.  No such function has
      ever existed in the mainline kernel.  Given that the change in this
      commit has been tested with DMA API debug enabled and shows no issue,
      I can only conclude that test_ahash_pnum() was triggering that bad
      behaviour by CAAM.

      Rearrange the last request handling for hashes which require software
      padding.

      We prepare the padding to be appended, and then append as much of the
      padding to any existing data that's already queued up, adding an
      operation block and launching the operation.

      Any remainder is then appended as a separate operation.

      This ensures that the hardware only ever sees multiples of the hash
      block size to be operated on for software padded hashes, thus ensuring
      that the engine always indicates that it has finished the calculation.

      crypto: marvell/cesa - ensure iter.base.op_len is the full op length

      When we process the last request of data, and the request contains user
      data, the loop in mv_cesa_ahash_dma_req_init() marks the first data size
      as being iter.base.op_len which does not include the size of the cache
      data.  This means we end up hashing an insufficient amount of data.

      Fix this by always including the cache size in the first operation
      length of any request.

      This has the effect that for a request containing no user data,

        iter.base.op_len === iter.src.op_offset === creq->cache_ptr

      As a result, we include one further change to use iter.base.op_len in
      the cache-but-no-user-data case to make the next change clearer.

      crypto: marvell/cesa - use presence of scatterlist to determine data load

      Use the presence of the scatterlist to determine whether we should load
      any new user data to the engine.  The following shall always be true at
      this point:

        iter.base.op_len == 0 === iter.src.sg

      In doing so, we can:

      1. eliminate the test for iter.base.op_len inside the loop, which
         makes the loop operation more obvious and understandable.

      2. move the operation generation for the cache-only case.

      This prepares the code for the next step in its transformation, and also
      uncovers a bug that will be fixed in the next patch.

      pinctrl: sh-pfc: r8a7794: Add VIN pin groups

      Add VIN0/1 pin groups to R8A7794 PFC driver.

      Sergei:  rebased, renamed, added changelog, gathered 12  VIN1 data pins 
into
      a single pin group, added "vin1_data10" pin group, used 'union vin_data' 
and
      VIN_DATA_PIN_GROUP() macro to describe VIN1 pins, reversed the order of  
the
      VIN1 pin groups, removed unneeded empty lines, fixed  VIN1 separator

      crypto: api - Only abort operations on fatal signal

      Currently a number of Crypto API operations may fail when a signal
      occurs.  This causes nasty problems as the caller of those operations
      are often not in a good position to restart the operation.

      In fact there is currently no need for those operations to be
      interrupted by user signals at all.  All we need is for them to
      be killable.

      This patch replaces the relevant calls of signal_pending with
      fatal_signal_pending, and wait_for_completion_interruptible with
      wait_for_completion_killable, respectively.

      arm64: Make 36-bit VA depend on EXPERT

      Commit 215399392fe4 (arm64: 36 bit VA) introduced 36-bit VA support for
      the arm64 kernel when the 16KB page configuration is enabled. While this
      is a valid hardware configuration, it's not something we want to
      encourage since it reduces the memory (and I/O) range that the kernel
      can access. Make this depend on EXPERT to avoid complaints of Linux not
      mapping the whole RAM, especially on platforms following the ARM
      recommended memory map.

      compiler, atomics, kasan: Provide READ_ONCE_NOCHECK()

      Some code may perform racy by design memory reads. This could be
      harmless, yet such code may produce KASAN warnings.

      To hide such accesses from KASAN this patch introduces
      READ_ONCE_NOCHECK() macro. KASAN will not check the memory
      accessed by READ_ONCE_NOCHECK(). The KernelThreadSanitizer
      (KTSAN) is going to ignore it as well.

      This patch creates __read_once_size_nocheck() a clone of
      __read_once_size(). The only difference between them is
      'no_sanitized_address' attribute appended to '*_nocheck'
      function. This attribute tells the compiler that instrumentation
      of memory accesses should not be applied to that function. We
      declare it as static '__maybe_unsed' because GCC is not capable
      to inline such function:
      https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67368

      With KASAN=n READ_ONCE_NOCHECK() is just a clone of READ_ONCE().

      The current ANY_CALL included direct, indirect calls and far jumps.

      We want to be able to differentiate indirect from direct calls. Therefore

      perf/x86: Fix time_shift in perf_event_mmap_page

      Commit:

        b20112edeadf ("perf/x86: Improve accuracy of perf/sched clock")

      allowed the time_shift value in perf_event_mmap_page to be as much
      as 32.  Unfortunately the documented algorithms for using time_shift
      have it shifting an integer, whereas to work correctly with the value
      32, the type must be u64.

      In the case of perf tools, Intel PT decodes correctly but the timestamps
      that are output (for example by perf script) have lost 32-bits of
      granularity so they look like they are not changing at all.

      Fix by limiting the shift to 31 and adjusting the multiplier accordingly.

      Also update the documentation of perf_event_mmap_page so that new code
      based on it will be more future-proof.

      stop_machine: Kill cpu_stop_threads->setup() and cpu_stop_unpark()

      Now that we always use stop_machine_unpark() to wake the stopper
      threas up, we can kill ->setup() and fold cpu_stop_unpark() into
      stop_machine_unpark().

      And we do not need stopper->lock to set stopper->enabled = true.

      stop_machine: Kill smp_hotplug_thread->pre_unpark, introduce 
stop_machine_unpark()

      1. Change smpboot_unpark_thread() to check ->selfparking, just
         like smpboot_park_thread() does.

      2. Introduce stop_machine_unpark() which sets ->enabled and calls
         kthread_unpark().

      3. Change smpboot_thread_call() and cpu_stop_init() to call
         stop_machine_unpark() by hand.

      This way:

          - IMO the ->selfparking logic becomes more consistent.

          - We can kill the smp_hotplug_thread->pre_unpark() method.

          - We can easily unpark the stopper thread earlier. Say, we
            can move stop_machine_unpark() from smpboot_thread_call()
            to sched_cpu_active() as Peter suggests.

      stop_machine: Change cpu_stop_queue_two_works() to rely on 
stopper->enabled

      Change cpu_stop_queue_two_works() to ensure that both CPU's have
      stopper->enabled == T or fail otherwise.

      This way stop_two_cpus() no longer needs to check cpu_active() to
      avoid the deadlock. This patch doesn't remove these checks, we will
      do this later.

      Note: we need to take both stopper->lock's at the same time, but this
      will also help to remove lglock from stop_machine.c, so I hope this
      is fine.

      stop_machine: Ensure that a queued callback will be called before 
cpu_stop_park()

      cpu_stop_queue_work() checks stopper->enabled before it queues the
      work, but ->enabled == T can only guarantee cpu_stop_signal_done()
      if we race with cpu_down().

      This is not enough for stop_two_cpus() or stop_machine(), they will
      deadlock if multi_cpu_stop() won't be called by one of the target
      CPU's. stop_machine/stop_cpus are fine, they rely on stop_cpus_mutex.
      But stop_two_cpus() has to check cpu_active() to avoid the same race
      with hotplug, and this check is very unobvious and probably not even
      correct if we race with cpu_up().

      Change cpu_down() pass to clear ->enabled before cpu_stopper_thread()
      flushes the pending ->works and returns with KTHREAD_SHOULD_PARK set.

      Note also that smpboot_thread_call() calls cpu_stop_unpark() which
      sets enabled == T at CPU_ONLINE stage, so this CPU can't go away until
      cpu_stopper_thread() is called at least once. This all means that if
      cpu_stop_queue_work() succeeds, we know that work->fn() will be called.

      sched/deadline: Fix migration of SCHED_DEADLINE tasks

      Commit:

        9d5142624256 ("sched/deadline: Reduce rq lock contention by eliminating 
locking of non-feasible target")

      broke select_task_rq_dl() and find_lock_later_rq(), because it introduced
      a comparison between the local task's deadline and dl.earliest_dl.curr of
      the remote queue.

      However, if the remote runqueue does not contain any SCHED_DEADLINE
      task its earliest_dl.curr is 0 (always smaller than the deadline of
      the local task) and the remote runqueue is not selected for pushing.

      As a result, if an application creates multiple SCHED_DEADLINE
      threads, they will never be pushed to runqueues that do not already
      contain SCHED_DEADLINE tasks.

      This patch fixes the issue by checking if dl.dl_nr_running == 0.

      nohz: Revert "nohz: Set isolcpus when nohz_full is set"

      This reverts:

        8cb9764fc88b ("nohz: Set isolcpus when nohz_full is set")

      We assumed that full-nohz users always want scheduler isolation on full
      dynticks CPUs, therefore we included full-nohz CPUs on cpu_isolated_map.

      This means that tasks run by default on CPUs outside the nohz_full range
      unless their affinity is explicity overwritten.

      This suits pure isolation workloads but when the machine is needed to
      run common workloads, the available sets of CPUs to run common tasks
      becomes reduced.

      We reach an extreme case when CONFIG_NO_HZ_FULL_ALL is enabled as it
      leaves only CPU 0 for non-isolation tasks, which makes people think that
      their supercomputer regressed to 90's UP - which is true in a sense.

      Some full-nohz users appear to be interested in running normal workloads
      either before or after an isolation workload. Full-nohz isn't optimized
      toward normal workloads but it's still better than UP performance.

      We are reaching a limitation in kernel presets here. Lets revert this
      cpu_isolated_map inclusion and let userspace do its own scheduler
      isolation using cpusets or explicit affinity settings.

      sched/fair: Update task group's load_avg after task migration

      When cfs_rq has cfs_rq->removed_load_avg set (when a task migrates from
      this cfs_rq), we need to update its contribution to the group's load_avg.

      This should not increase tg's update too much, because in most cases, the
      cfs_rq has already decayed its load_avg.

      sched/fair: Fix overly small weight for interactive group entities

      Commit:

        9d89c257dfb9 ("sched/fair: Rewrite runnable load and utilization 
average tracking")

      led to an overly small weight for interactive group entities. The bad case
      can be easily reproduced when a number of CPU hogs compete for the CPUs
      at the same time (thanks to Mike). This is largly because the task group's
      load average tracking cross CPUs lags behind the real changes.

      To fix this we accelerate the group share distribution process by using
      the load.weight of the cfs_rq. This may increase the entire group's
      share, but we have to do so to protect the (fragile) interactive
      tasks, especially from CPU hogs.

      i40e: fix for PHY NVM interaction problem

      This patch fixes a problem where the NVMUpdate Tool, when using the PHY
      NVM feature, gets bad data from the PHY because of contention on the
      MDIO interface from get PHY capability calls from the driver during
      regular operations.  The problem is fixed by adding a check if media
      is available before calling get PHY capability function because that
      bit is not set when device is in PHY interaction mode.

      i40e/i40evf: adjust interrupt throttle less frequently

      The adaptive ITR (interrupt throttle rate) algorithm was adjusting
      the hardware's interrupt rate too frequently.  This caused a lot
      of variation in the interrupt rate for fairly constant workloads.

      Change the code to have a counter and adjust only once every N
      number of interrupts.

      i40e/i40evf: change dynamic interrupt thresholds

      The dynamic algorithm, while now working, doesn't have good
      performance in 40G mode.

      One part of this patch addresses the high CPU utilization of some small
      streaming workloads that the driver should reduce CPU in.

      It also changes the minimum ITR that the dynamic algorithm
      will settle on, causing our minimum latency to go from 12us
      to about 14us, when using adaptive mode.

      It also changes the BULK interrupt rate to allow maximum throughput
      on a 40Gb connection with a single thread of transmit, clamping
      interrupt rate to 8000 for TX makes single thread traffic go too
      slow.

      The new ULTRA bulk setting is introduced and is used
      when the Rx packet rate on this queue exceeds 40000 packets per
      second.  This value of 40000 was chosen because the automatic tuning
      of minimum ITR=20us means that a single queue can't quite achieve
      that many packets per second from a round-robin test.

      When the VF driver is unable to communicate with the PF, it just gives

      When PF communications fail, wait five seconds, and try again. And
      again. Don't give up, little VF driver! Your prince will come!

      modify_ldt() was declared as an external symbol. Despite the man
      page for this syscall telling that there is no wrapper in glibc,
      since version 2.1 there actually is, so linking to the glibc
      works.

      Since modify_ldt() is not a POSIX interface, other libc
      implementations do not always provide a wrapper function.
      Even glibc headers do not provide a corresponding declaration.

      So go the recommended way to call this using syscall().

      For out-of-tree builds, we must not rely on relative paths.

      clocksource/drivers/armada-370-xp: Implement ARM delay timer

      Implement an ARM delay timer to be used for udelay() on Armada 37x
      platforms.  This allows us to skip the delay loop calibration at boot,
      saving 180ms on the boot time of the kernel (which is around 10%).

      It also means that udelay() will be unaffected by CPU frequency changes
      when cpufreq is enabled on these platforms.

      perf bench: Harmonize all the -l/--nr_loops options

      We have three benchmarking subsystems that specify some sort of 'number
      of loops' parameter - but all of them do it inconsistently:

       numa:              -l/--nr_loops
       sched messaging:   -l/--loops
       mem memset/memcpy: -i/--iterations

      Harmonize them to -l/--nr_loops by picking the numa variant - which is
      also the most likely one to have existing scripting which we don't want
      to break.

      Plus improve the parameter help texts to indicate the default value for
      the nr_loops variable to keep users from guessing ...

      Also propagate the naming to internal variables.

      perf bench: Remove the prefaulting complication from 'perf bench mem mem*'

      So 'perf bench mem memcpy/memset' has elaborate code to measure
      memcpy()/memset() performance both with freshly allocated buffers (which
      includes initial page fault overhead) and with preallocated buffers.

      But the thing is, the resulting bandwidth results are mostly
      meaningless, because page faults dominate so much of the cost.

      It might make sense to measure cache cold vs. cache hot performance, but
      the code does not do this.

      So remove this complication, and always prefault the ranges before using
      them.

        vega:~> perf bench mem all
        # Running mem/memcpy benchmark...
        Routine default (Default memcpy() provided by glibc)
        # Copying 1MB Bytes ...

             894.454383 MB/Sec
               3.844734 GB/Sec (with prefault)

        # Running mem/memset benchmark...
        Routine default (Default memset() provided by glibc)
        # Copying 1MB Bytes ...

               1.220703 GB/Sec
               9.042245 GB/Sec (with prefault)

      Because misleadingly the 'all' refers to 'all sub-benchmarks', not 'all
      sub-benchmarks and routines'.

      Fix all this by making the memcpy/memset routine to default to 'all',
      which results in all the benchmarks being run:

      perf test: Suppress libtraceevent warnings

      Currently libtraceevent emits warning on unsupported event formats.
      However it'd be better to see them only -v option is given.  To do that,
      it needs to override the warning() function which is used in the
      libtracevent.  Thus add set_warning_routine() same as set_die_routine()
      and check the verbose flag in our warning routine.

      Before:
        # perf test 5
         5: parse events tests                                       :

      perf test: Silence tracepoint event failures

      Currently, when 'perf test' is run by a normal user, it'll fail to
      access tracepoint events.  The output becomes somewhat messy because it
      tries to be nice with long error messages and hints.

      IMHO this is not needed for 'perf test' by default and AFAIK 'perf test'
      uses pr_debug() rather than pr_err() for such messages so that one can
      use -v option to see further details on failed testcases if needed.

      arm64: Synchronise dump_backtrace() with perf callchain

      Unlike perf callchain relying on walk_stackframe(), dump_backtrace()
      has its own backtrace logic. A major difference between them is the
      moment a symbol is recorded. Perf writes down a symbol *before*
      calling unwind_frame(), but dump_backtrace() prints it out *after*
      unwind_frame(). As a result, the last valid symbol cannot be hooked
      in case of dump_backtrace(). This patch addresses the issue as
      synchronising dump_backtrace() with perf callchain.

      A simple test and its results are as follows:

      - crash trigger

       $ sudo echo c > /proc/sysrq-trigger

      - current status

       Call trace:
       [<fffffe00003dc738>] sysrq_handle_crash+0x24/0x30
       [<fffffe00003dd2ac>] __handle_sysrq+0x128/0x19c
       [<fffffe00003dd730>] write_sysrq_trigger+0x60/0x74
       [<fffffe0000249fc4>] proc_reg_write+0x84/0xc0

       [<fffffe00001f2e60>] vfs_write+0x98/0x1a8
       [<fffffe00001f3730>] SyS_write+0x50/0xb0

      - with this change

       Call trace:
       [<fffffe00003dc738>] sysrq_handle_crash+0x24/0x30
       [<fffffe00003dd2ac>] __handle_sysrq+0x128/0x19c
       [<fffffe00003dd730>] write_sysrq_trigger+0x60/0x74
       [<fffffe0000249fc4>] proc_reg_write+0x84/0xc0
       [<fffffe00001f2638>] __vfs_write+0x44/0x104

       [<fffffe00000939ec>] el0_svc_naked+0x20/0x28

      Note that this patch does not cover a case where MMU is disabled. The
      last stack frame of swapper, for example, has PC in a form of physical
      address. Unfortunately, a simple conversion using phys_to_virt() cannot
      cover all scenarios since PC is retrieved from LR - 4, not LR. It is
      a big tradeoff to change both head.S and unwind_frame() for only a few
      of symbols in *.S. Thus, this hunk does not take care of the case.

      arm64: Add 16K page size support

      This patch turns on the 16K page support in the kernel. We
      support 48bit VA (4 level page tables) and 47bit VA (3 level
      page tables).

      With 16K we can map 128 entries using contiguous bit hint
      at level 3 to map 2M using single TLB entry.

      TODO: 16K supports 32 contiguous entries at level 2 to get us
      1G(which is not yet supported by the infrastructure). That should
      be a separate patch altogether.

      Install a non-faulting handler just before unmasking imprecise aborts
      and switch back to the regular one after unmasking is done.

      This catches any pending imprecise abort that the firmware/bootloader
      may have left behind that would normally crash the kernel at that point.
      As there are apparently a lot of bootlaoders out there that do such a

      ARM: OMAP2+: Fix imprecise external abort caused by bogus SRAM init

      Some omaps are producing imprecise external aborts because we are
      wrongly trying to init SRAM for device tree based booting. Only
      omap3 is still using the legacy SRAM code, so we need to make it
      omap3 specific. Otherwise we can get errors like this on at least
      dm814x:

      Unhandled fault: imprecise external abort (0xc06) at 0xc08b156c
      ...

      (kernel_init) from [<c000f890>] (ret_from_fork+0x14/0x24)

      Let's fix the issue by making sure omap_sdrc_init only gets called for
      omap3. To do that, we need to have compatible "ti,omap3" in the dts
      files. And let's also use "ti,omap3630" instead of "ti,omap36xx" like
      we're supposed to.

      ath10k: disable PCI PS for QCA988X and QCA99X0

      This patch disables PCI PS for QCA988X and QCA99X0, Since PCI PS is
      validated for QCA6174, let it be enabled only for QCA6174. It would be
      better to execute PCI PS related functions only for the supported devices.

      PCI time out issue is observed with QCA99X0 on x86 platform, We will
      disable PCI PS for QCA988X and QCA99X0 until PCI PS is properly 
implemented.

      Taking and releasing ps_lock is causing higher CPU consumption. Michal 
Kazior
      suggested ps_lock overhead to be reworked so that ath10k_pci_wake/sleep
      functions are called less often, i.e. move the powersave logic up (only 
during
      irq handling, tx path, submitting fw commands) but that's a bigger change 
and
      can be implemented later.

      be set at all, so we fail dispatch to the inner address family.
      As a reault, the local error handler is not called and the
      mtu value is not reported back to userspace.

      We fix this by setting skb->protocol on message size errors
      before we call xfrm_local_error.

      x86, kasan: Fix build failure on KASAN=y && KMEMCHECK=y kernels

      Declaration of memcpy() is hidden under #ifndef CONFIG_KMEMCHECK.
      In asm/efi.h under #ifdef CONFIG_KASAN we #undef memcpy(), due to
      which the following happens:

        In file included from arch/x86/kernel/setup.c:96:0:
        ./arch/x86/include/asm/desc.h: In function â??native_write_idt_entryâ??:
        ./arch/x86/include/asm/desc.h:122:2: error: implicit declaration of 
function â??memcpyâ?? [-Werror=implicit-function-declaration]

          ^
          cc1: some warnings being treated as errors
          make[2]: *** [arch/x86/kernel/setup.o] Error 1

      We will get rid of that #undef in asm/efi.h eventually.
      But in the meanwhile move memcpy() declaration out of #ifdefs
      to fix the build.

      x86/smpboot: Fix CPU #1 boot timeout

      The following commit:

        a9bcaa02a5104ac ("x86/smpboot: Remove SIPI delays from cpu_up()")

      Caused some Intel Core2 processors to time-out when bringing up CPU #1,
      resulting in the missing of that CPU after bootup.

      That patch reduced the SIPI delays from udelay() 300, 200 to udelay() 0,
      0 on modern processors.

      Several Intel(R) Core(TM)2 systems failed to bring up CPU #1 10/10 times
      after that change.

      Increasing either of the SIPI delays to udelay(1) results in
      success. So here we increase both to udelay(10).  While this may
      be 20x slower than the absolute minimum, it is still 20x to 30x
      faster than the original code.

      x86/smpboot: Fix cpu_init_udelay=10000 corner case boot parameter 
misbehavior

      For legacy machines cpu_init_udelay defaults to 10,000.
      For modern machines it is set to 0.

      The user should be able to set cpu_init_udelay to
      any value on the cmdline, including 10,000.

      Before this patch, that was seen as "unchanged from default"
      and thus on a modern machine, the user request was ignored
      and the delay was set to 0.

      net: bcmgenet: Fix early link interrupt enabling

      Link interrupts are enabled in init_umac(), which is too early for us to
      process them since we do not yet have a valid PHY device pointer. On
      BCM7425 chips for instance, we will crash calling phy_mac_interrupt()
      because phydev is NULL.

      Fix this by moving the link interrupts enabling in
      bcmgenet_netif_start(), under a specific function:
      bcmgenet_link_intr_enable() and while at it, update the comments
      surrounding the code.

      Netfilter/IPVS updates for net-next

      The following patchset contains Netfilter/IPVS updates for your net-next
      tree. Most relevantly, updates for the nfnetlink_log to integrate with
      conntrack, fixes for cttimeout and improvements for nf_queue core, they 
are:

      1) Remove useless ifdef around static inline function in IPVS, from
         Eric W. Biederman.

      2) Simplify the conntrack support for nfnetlink_queue: Merge
         nfnetlink_queue_ct.c file into nfnetlink_queue_core.c, then rename it 
back
         to nfnetlink_queue.c

      3) Use y2038 safe timestamp from nfnetlink_queue.

      4) Get rid of dead function definition in nf_conntrack, from Flavio
         Leitner.

      5) Attach conntrack support for nfnetlink_log.c, from Ken-ichirou 
MATSUZAWA.
         This adds a new NETFILTER_NETLINK_GLUE_CT Kconfig switch that
         controls enabling both nfqueue and nflog integration with conntrack.
         The userspace application can request this via NFULNL_CFG_F_CONNTRACK
         configuration flag.

      6) Remove unused netns variables in IPVS, from Eric W. Biederman and
         Simon Horman.

      7) Don't put back the refcount on the cttimeout object from xt_CT on 
success.

      8) Fix crash on cttimeout policy object removal. We have to flush out
         the cttimeout extension area of the conntrack not to refer to an 
unexisting
         object that was just removed.

      9) Make sure rcu_callback completion before removing nfnetlink_cttimeout
         module removal.

      10) Fix compilation warning in br_netfilter when no nf_defrag_ipv4 and
          nf_defrag_ipv6 are enabled. Patch from Arnd Bergmann.

      11) Autoload ctnetlink dependencies when NFULNL_CFG_F_CONNTRACK is
          requested. Again from Ken-ichirou MATSUZAWA.

      12) Don't use pointer to previous hook when reinjecting traffic via
          nf_queue with NF_REPEAT verdict since it may be already gone. This
          also avoids a deadloop if the userspace application keeps returning
          NF_REPEAT.

      13) A bunch of cleanups for netfilter IPv4 and IPv6 code from Ian Morris.

      14) Consolidate logger instance existence check in nfulnl_recv_config().

      15) Fix broken atomicity when applying configuration updates to logger
          instances in nfnetlink_log.

      16) Get rid of the .owner attribute in our hook object. We don't need
          this anymore since we're dropping pending packets that have escaped
          from the kernel when unremoving the hook. Patch from Florian Westphal.

      17) Remove unnecessary rcu_read_lock() from nf_reinject code, we always
          assume RCU read side lock from .call_rcu in nfnetlink. Also from 
Florian.

      18) Use static inline function instead of macros to define NF_HOOK() and
          NF_HOOK_COND() when no netfilter support in on, from Arnd Bergmann.

      RDS: fix rds-ping deadlock over TCP transport

      Sowmini found hang with rds-ping while testing RDS over TCP. Its
      a corner case and doesn't happen always. The issue is not reproducible
      with IB transport. Its clear from below dump why we see it with RDS TCP.

       [<ffffffffa0960cdb>] ? rds_tcp_write_space+0xbb/0x110 [rds_tcp]

       [<ffffffff8152e0b3>] ip_local_deliver_finish+0xa3/0x220

      This happens because rds_send_xmit() chain wants to take
      sock_lock which is already taken by tcp_v4_rcv() on its
      way to rds_tcp_data_ready(). Commit db6526dcb51b ("RDS: use
      rds_send_xmit() state instead of RDS_LL_SEND_FULL") which
      was trying to opportunistically finish the send request
      in same thread context.

      But because of above recursive lock hang with RDS TCP,
      the send work from rds_send_pong() needs to deferred to
      worker to avoid lock up. Given RDS ping is more of connectivity
      test than performance critical path, its should be ok even
      for transport like IB.

      tunnels: Don't require remote endpoint or ID during creation.

      Before lightweight tunnels existed, it really didn't make sense to
      create a tunnel that was not fully specified, such as without a
      destination IP address - the resulting packets would go nowhere.
      However, with lightweight tunnels, the opposite is true - it doesn't
      make sense to require this information when it will be provided later
      on by the route. This loosens the requirements for this information.

      An alternative would be to allow the relaxed version only when
      COLLECT_METADATA is enabled. However, since there are several
      variations on this theme (such as NBMA tunnels in GRE), just dropping
      the restrictions seems the most consistent across tunnels and with
      the existing configuration.

      At the time of commit fff326990789 ("tcp: reflect SYN queue_mapping into
      SYNACK packets") we had little ways to cope with SYN floods.

      We no longer need to reflect incoming skb queue mappings, and instead
      can pick a TX queue based on cpu cooking the SYNACK, with normal XPS
      affinities.

      Note that all SYNACK retransmits were picking TX queue 0, this no longer
      is a win given that SYNACK rtx are now distributed on all cpus.

      openvswitch: Scrub skb between namespaces

      If OVS receives a packet from another namespace, then the packet should
      be scrubbed. However, people have already begun to rely on the behaviour
      that skb->mark is preserved across namespaces, so retain this one field.

      This is mainly to address information leakage between namespaces when
      using OVS internal ports, but by placing it in ovs_vport_receive() it is
      more generally applicable, meaning it should not be overlooked if other
      port types are allowed to be moved into namespaces in future.

      pull request: bluetooth 2015-10-16

      First of all, sorry for the late set of patches for the 4.3 cycle. We
      just finished an intensive week of testing at the Bluetooth UnPlugFest
      and discovered (and fixed) issues there. Unfortunately a few issues
      affect 4.3-rc5 in a way that they break existing Bluetooth LE mouse and
      keyboard support.

      The regressions result from supporting LE privacy in conjunction with
      scanning for Resolvable Private Addresses before connecting. A feature
      that has been tested heavily (including automated unit tests), but sadly
      some regressions slipped in. The UnPlugFest with its multitude of test
      platforms is a good battle testing ground for uncovering every corner
      case.

      The patches in this pull request focus only on fixing the regressions in
      4.3-rc5. The patches look a bit larger since we also added comments in
      the critical sections of the fixes to improve clarity.

      I would appreciate if we can get these regression fixes to Linus
      quickly. Please let me know if there are any issues pulling. Thanks.

      net: hix5hd2_gmac: avoid integer overload warning

      BITS_RX_EN is an 'unsigned long' constant, so the ones complement of that
      has bits set that do not fit into a 32-bit variable on 64-bit 
architectures,
      which causes a harmless gcc warning:

'hix5hd2_port_disable':

        writel_relaxed(~(BITS_RX_EN | BITS_TX_EN), priv->base + PORT_EN);

      This adds a cast to (u32) to tell gcc that the code is indeed fine.

      This clarifies the dependency to ensure we don't attempt to build these

      Build-tested on x86 as well to ensure this actually works.

declaration of function 'vzalloc' [-Werror=implicit-function-declaration]
        priv->soft_mac_tbl = vzalloc(sizeof(*priv->soft_mac_tbl)

      This adds the correct #include.

      net: hns: fixes a bug about timeout by pause frame

      this patch fixes the bug triggered timeout sequence. when the connective
      ports cannot accept the packets with higher speed, they will send out the
      pause frame to the Soc's mac. At that time, the driver resets the relevant
      of the Soc, then it causes the packets cannot be sent out immediately.
      this patch fixes the issue.

        before this patch, hns driver only permits user to set the net device
      by using ethtool -s when the device is link up. it is obviously not so
      good. it needs to be set no matter it is link up or down. so this patch
      fixes this issue.

      netlink: Trim skb to alloc size to avoid MSG_TRUNC

      netlink_dump() allocates skb based on the calculated min_dump_alloc or
      a per socket max_recvmsg_len.
      min_alloc_size is maximum space required for any single netdev
      attributes as calculated by rtnl_calcit().
      max_recvmsg_len tracks the user provided buffer to netlink_recvmsg.
      It is capped at 16KiB.
      The intention is to avoid small allocations and to minimize the number
      of calls required to obtain dump information for all net devices.

      netlink_dump packs as many small messages as could fit within an skb
      that was sized for the largest single netdev information. The actual
      space available within an skb is larger than what is requested. It could
      be much larger and up to near 2x with align to next power of 2 approach.

      Allowing netlink_dump to use all the space available within the
      allocated skb increases the buffer size a user has to provide to avoid
      truncaion (i.e. MSG_TRUNG flag set).

      It was observed that with many VLANs configured on at least one netdev,
      a larger buffer of near 64KiB was necessary to avoid "Message truncated"
      error in "ip link" or "bridge [-c[ompressvlans]] vlan show" when
      min_alloc_size was only little over 32KiB.

      This patch trims skb to allocated size in order to allow the user to
      avoid truncation with more reasonable buffer size.

      ipconfig: send Client-identifier in DHCP requests

      A dhcp server may provide parameters to a client from a pool of IP
      addresses and using a shared rootfs, or provide a specific set of
      parameters for a specific client, usually using the MAC address to
      identify each client individually. The dhcp protocol also specifies
      a client-id field which can be used to determine the correct
      parameters to supply when no MAC address is available. There is
      currently no way to tell the kernel to supply a specific client-id,
      only the userspace dhcp clients support this feature, but this can
      not be used when the network is needed before userspace is available
      such as when the root filesystem is on NFS.

      This patch is to be able to do something like "ip=dhcp,client_id_type,
      client_id_value", as a kernel parameter to enable the kernel to
      identify itself to the server.

      i2c: designware: Do not use parameters from ACPI on Dell Inspiron 7348

      ACPI SSCN/FMCN methods were originally added because then the platform can
      provide the most accurate HCNT/LCNT values to the driver. However, this
      seems not to be true for Dell Inspiron 7348 where using these causes the
      touchpad to fail in boot:

        i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
        i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration
        i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
        i2c_designware INT3433:00: controller timed out

      The values received from ACPI are (in fast mode):

        HCNT: 72
        LCNT: 160

      this translates to following timings (input clock is 100MHz on Broadwell):

        tHIGH: 720 ns (spec min 600 ns)
        tLOW: 1600 ns (spec min 1300 ns)
        Bus period: 2920 ns (assuming 300 ns tf and tr)
        Bus speed: 342.5 kHz

      Both tHIGH and tLOW are within the I2C specification.

      The calculated values when ACPI parameters are not used are (in fast 
mode):

        HCNT: 87
        LCNT: 159

      which translates to:

        tHIGH: 870 ns (spec min 600 ns)
        tLOW: 1590 ns (spec min 1300 ns)
        Bus period 3060 ns (assuming 300 ns tf and tr)
        Bus speed 326.8 kHz

      These values are also within the I2C specification.

      Since both ACPI and calculated values meet the I2C specification timing
      requirements it is hard to say why the touchpad does not function properly
      with the ACPI values except that the bus speed is higher in this case (but
      still well below the max 400kHz).

      Solve this by adding DMI quirk to the driver that disables using ACPI
      parameters on this particulare machine.

      Input: lpc32xx_ts - fix warnings caused by enabling unprepared clock

      If common clock framework is configured, the driver generates a warning,
      which is fixed by this change:

      ARC: [arcompact] entry.S: Improve early return from exception

      The requirement is to
       - Reenable Exceptions (AE cleared)
       - Reenable Interrupts (E1/E2 set)

      We need to do wiggle these bits into ERSTATUS and call RTIE.

      Prev version used the pre-exception STATUS32 as starting point for what
      goes into ERSTATUS. This required explicit fixups of U/DE/L bits.

      Instead, use the current (in-exception) STATUS32 as starting point.
      Being in exception handler U/DE/L can be safely assumed to be correct.
      Only AE/E1/E2 need to be fixed.

      So the new implementation is slightly better
       -Avoids read form memory
       -Is 4 bytes smaller for the typical 1 level of intr configuration
       -Depicts the semantics more clearly

      ARC: [arcompact] don't check for hard isr calling local_irq_enable()

      Historically this was done by ARC IDE driver, which is long gone.
      IRQ core is pretty robust now and already checks if IRQs are enabled
      in hard ISRs. Thus no point in checking this in arch code, for every
      call of irq enabled.

      Further if some driver does do that - let it bring down the system so we
      notice/fix this sooner than covering up for sucker

      This makes local_irq_enable() - for L1 only case atleast simple enough
      so we can inline it.

      mm,thp: introduce flush_pmd_tlb_range

      ARCHes with special requirements for evicting THP backing TLB entries
      can implement this.

      Otherwise also, it can help optimize TLB flush in THP regime.
      stock flush_tlb_range() typically has optimization to nuke the entire
      TLB if flush span is greater than a certain threshhold, which will
      likely be true for a single huge page. Thus a single thp flush will
      invalidate the entrire TLB which is not desirable.

      ARCv2: mm: THP support

      MMUv4 in HS38x cores supports Super Pages which are basis for Linux THP
      support.

      Normal and Super pages can co-exist (ofcourse not overlap) in TLB with a
      new bit "SZ" in TLB page desciptor to distinguish between them.
      Super Page size is configurable in hardware (4K to 16M), but fixed once
      RTL builds.

      The exact THP size a Linx configuration will support is a function of:
       - MMU page size (typical 8K, RTL fixed)
       - software page walker address split between PGD:PTE:PFN (typical
         11:8:13, but can be changed with 1 line)

      So for above default, THP size supported is 8K * 256 = 2M

      Default Page Walker is 2 levels, PGD:PTE:PFN, which in THP regime
      reduces to 1 level (as PTE is folded into PGD and canonically referred
      to as PMD).

      Thus thp PMD accessors are implemented in terms of PTE (just like sparc)

      net: add pfmemalloc check in sk_add_backlog()

      Greg reported crashes hitting the following check in __sk_backlog_rcv()

        BUG_ON(!sock_flag(sk, SOCK_MEMALLOC));

      The pfmemalloc bit is currently checked in sk_filter().

      This works correctly for TCP, because sk_filter() is ran in
      tcp_v[46]_rcv() before hitting the prequeue or backlog checks.

      For UDP or other protocols, this does not work, because the sk_filter()
      is ran from sock_queue_rcv_skb(), which might be called _after_ backlog
      queuing if socket is owned by user by the time packet is processed by
      softirq handler.

      netfilter: ipset: Fix sleeping memory allocation in atomic context

      Commit 00590fdd5be0 introduced RCU locking in list type and in
      doing so introduced a memory allocation in list_set_add, which
      is done in an atomic context, due to the fact that ipset rcu
      list modifications are serialised with a spin lock. The reason
      why we can't use a mutex is that in addition to modifying the
      list with ipset commands, it's also being modified when a
      particular ipset rule timeout expires aka garbage collection.
      This gc is triggered from set_cleanup_entries, which in turn
      is invoked from a timer thus requiring the lock to be bh-safe.

      Concretely the following call chain can lead to "sleeping function
      called in atomic context" splat:
      call_ad -> list_set_uadt -> list_set_uadd -> kzalloc(, GFP_KERNEL).
      And since GFP_KERNEL allows initiating direct reclaim thus
      potentially sleeping in the allocation path.

      To fix the issue change the allocation type to GFP_ATOMIC, to
      correctly reflect that it is occuring in an atomic context.

      xhci: Add spurious wakeup quirk for LynxPoint-LP controllers

      We received several reports of systems rebooting and powering on
      after an attempted shutdown. Testing showed that setting
      XHCI_SPURIOUS_WAKEUP quirk in addition to the XHCI_SPURIOUS_REBOOT
      quirk allowed the system to shutdown as expected for LynxPoint-LP
      xHCI controllers. Set the quirk back.

      Note that the quirk was originally introduced for LynxPoint and
      LynxPoint-LP just for this same reason. See:

      commit 638298dc66ea ("xhci: Fix spurious wakeups after S5 on Haswell")

      It was later limited to only concern HP machines as it caused
      regression on some machines, see both bug and commit:

      Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=66171
      commit 6962d914f317 ("xhci: Limit the spurious wakeup fix only to HP 
machines")

      Later it was discovered that the powering on after shutdown
      was limited to LynxPoint-LP (Haswell-ULT) and that some non-LP HP
      machine suffered from spontaneous resume from S3 (which should
      not be related to the SPURIOUS_WAKEUP quirk at all). An attempt
      to fix this then removed the SPURIOUS_WAKEUP flag usage completely.

      commit b45abacde3d5 ("xhci: no switching back on non-ULT Haswell")

      Current understanding is that LynxPoint-LP (Haswell ULT) machines
      need the SPURIOUS_WAKEUP quirk, otherwise they will restart, and
      plain Lynxpoint (Haswell) machines may _not_ have the quirk
      set otherwise they again will restart.

      xhci: don't finish a TD if we get a short transfer event mid TD

      If the difference is big enough between the bytes asked and received
      in a bulk transfer we can get a short transfer event pointing to a TRB in
      the middle of the TD. We don't want to handle the TD yet as we will anyway
      receive a new event for the last TRB in the TD.

      Hold off from finishing the TD and removing it from the list until we
      receive an event for the last TRB in the TD

      gpiolib: Split GPIO flags parsing and GPIO configuration

      When requesting a GPIO through the legacy or the gpiod_* API the
      gpiochip request operation is first called and then the GPIO flags are
      parsed and the GPIO is configured. This prevents the gpiochip from
      rejecting the request if the flags are not supported by the device.

      To fix this split the parse-and-configure operation in two and parse
      flags before requesting the GPIO.

      pinctrl: atlas7: support atlas7 step B changes

      The the pin groups and pin functions have been changed
      in atlas7 step B soc. We have to update the driver
      to support step B chip.

      Changes:
      1. add 5 jtag pins to IOC_TOP:
        "jtag_tdo", "jtag_tms","jtag_tck", "jtag_tdi", "jtag_trstn"
        these 5 pins can be mutiplex with other functions, so we
        have to conver these 5 pins in pinmux.
      2. add pin groups for audio digmic, audio spdif, can transceiver
        en, can transceiver stb, i2s0, i2s1 and jtag.
      3. serval pins can be located to more PADs:
        audio_uart0_urfs, audio_uart1_urfs, audio_uart2_urfs,
        audio_uart2_urxd, audio_uart2_usclk, audio_uart2_utfs,
        audio_uart2_utxd, can0_rxd, can0_txd, can1_rxd, can1_txd
        jtag_ntrst, jtag_swdiotms, jtag_tck, jtag_tdi, jtag_tdo,
        pw_cko0, pw_cko1, pw_i2s01, pw_pwm0, pw_pwm1, sd2_cdb,
        sd2_wpb, uart2_cts, uart2_rts, uart2_rxd, uart2_txd,
        uart3_cts, uart3_rts, uart3_rxd, uart3_txd, uart4_cts,
        uart4_rts, usb0_drvvbus, usb1_drvvbus.

      Because of Changes#3, some functions should have more than one
      pin groups. So we have to split the original pin group to serval
      pin groups.

      For example:
      audio_uart0 has 5 pins, on STEPA, each of these 5 pins only has
      one related PAD. But on STEPB, audio_uart0_urfs has 4 related
      PAD.
      So we place the 4 pins with one PAD into a single pin group:
        audio_uart0_basic_group.
      and place urfs pin wtih different PADs to 4 different pin groups:
        audio_uart0_urfs_group0, ..., audio_uart0_urfs_group3

      A full audio_uart0 pin group can be:
        pinctrl-0 = <&audio_uart0_basic_group &audio_uart0_urfs_group0>;
      If audio_uart0 pin group encountered some confiction, we only have
      to change the urfs group:
        pinctrl-0 = <&audio_uart0_basic_group &audio_uart0_urfs_group2>;

      sh: add copy_user_page() alias for __copy_user()

      copy_user_page() is needed by DAX.  Without this we get a compile error
      for DAX on SH:

        fs/dax.c:280:2: error: implicit declaration of function

      This was done with a random config that happened to include DAX support.

      This patch has only been compile tested.

      mm, dax: fix DAX deadlocks

      The following two locking commits in the DAX code:

      commit 843172978bb9 ("dax: fix race between simultaneous faults")
      commit 46c043ede471 ("mm: take i_mmap_lock in unmap_mapping_range() for 
DAX")

      introduced a number of deadlocks and other issues which need to be fixed
      for the v4.3 kernel.  The list of issues in DAX after these commits
      (some newly introduced by the commits, some preexisting) can be found
      here:

        https://lkml.org/lkml/2015/9/25/602 (Subject: "Re: [PATCH] dax: fix 
deadlock in __dax_fault").

      This undoes most of the changes introduced by those two commits,
      essentially returning us to the DAX locking scheme that was used in
      v4.2.

      builddeb: remove debian/files before build

      Commit 3716001bcb7f ("deb-pkg: add source package") added the ability to
      create a debian changelog file.  This exposed that previously the
      builddeb script hasn't cleared debian/files between builds.

      As debian/files keeps accumulating entries, the changes file will end up
      growing indefinelty.  With outdated entries in debian/files, builddeb
      script will exit with failure.  This regression impacts those who use
      "make deb-pkg" target to build kernel into a .deb package and never use
      "make mrproper" or other means to clean kernel tree from generated
      directories.

      To fix the regression, remove debian/files before starting build and in
      the generated clean rule.

      mm, fs: obey gfp_mapping for add_to_page_cache()

      Commit 6afdb859b710 ("mm: do not ignore mapping_gfp_mask in page cache
      allocation paths") has caught some users of hardcoded GFP_KERNEL used in
      the page cache allocation paths.  This, however, wasn't complete and
      there were others which went unnoticed.

      Dave Chinner has reported the following deadlock for xfs on loop device:
      : With the recent merge of the loop device changes, I'm now seeing
      : XFS deadlock on my single CPU, 1GB RAM VM running xfs/073.
      :
      : The deadlocked is as follows:
      :
      : kloopd1: loop_queue_read_work
      :       xfs_file_iter_read
      :       lock XFS inode XFS_IOLOCK_SHARED (on image file)
      :       page cache read (GFP_KERNEL)
      :       radix tree alloc
      :       memory reclaim
      :       reclaim XFS inodes
      :       log force to unpin inodes
      :       <wait for log IO completion>
      :
      : xfs-cil/loop1: <does log force IO work>
      :       xlog_cil_push
      :       xlog_write
      :       <loop issuing log writes>
      :               xlog_state_get_iclog_space()
      :               <blocks due to all log buffers under write io>
      :               <waits for IO completion>
      :
      : kloopd1: loop_queue_write_work
      :       xfs_file_write_iter
      :       lock XFS inode XFS_IOLOCK_EXCL (on image file)
      :       <wait for inode to be unlocked>
      :
      : i.e. the kloopd, with it's split read and write work queues, has
      : introduced a dependency through memory reclaim. i.e. that writes
      : need to be able to progress for reads make progress.
      :
      : The problem, fundamentally, is that mpage_readpages() does a
      : GFP_KERNEL allocation, rather than paying attention to the inode's
      : mapping gfp mask, which is set to GFP_NOFS.
      :
      : The didn't used to happen, because the loop device used to issue
      : reads through the splice path and that does:
      :
      :       error = add_to_page_cache_lru(page, mapping, index,
      :                       GFP_KERNEL & mapping_gfp_mask(mapping));

      This has changed by commit aa4d86163e4 ("block: loop: switch to VFS
      ITER_BVEC").

      This patch changes mpage_readpage{s} to follow gfp mask set for the
      mapping.  There are, however, other places which are doing basically the
      same.

      lustre:ll_dir_filler is doing GFP_KERNEL from the function which
      apparently uses GFP_NOFS for other allocations so let's make this
      consistent.

      cifs:readpages_get_pages is called from cifs_readpages and
      __cifs_readpages_from_fscache called from the same path obeys mapping
      gfp.

      ramfs_nommu_expand_for_mapping is hardcoding GFP_KERNEL as well
      regardless it uses mapping_gfp_mask for the page allocation.

      ext4_mpage_readpages is the called from the page cache allocation path
      same as read_pages and read_cache_pages

      As I've noticed in my previous post I cannot say I would be happy about
      sprinkling mapping_gfp_mask all over the place and it sounds like we
      should drop gfp_mask argument altogether and use it internally in
      __add_to_page_cache_locked that would require all the filesystems to use
      mapping gfp consistently which I am not sure is the case here.  From a
      quick glance it seems that some file system use it all the time while
      others are selective.

      netfilter: turn NF_HOOK into an inline function

      A recent change to the dst_output handling caused a new warning
      when the call to NF_HOOK() is the only used of a local variable
      passed as 'dev', and CONFIG_NETFILTER is disabled:

      net/ipv6/ip6_output.c: In function 'ip6_output':
      net/ipv6/ip6_output.c:135:21: warning: unused variable 'dev' 
[-Wunused-variable]

      The reason for this is that the NF_HOOK macro in this case does
      not reference the variable at all, and the call to dev_net(dev)
      got removed from the ip6_output function. To avoid that warning now
      and in the future, this changes the macro into an equivalent
      inline function, which tells the compiler that the variable is
      passed correctly but still unused.

      The dn_forward function apparently had the same problem in
      the past and added a local workaround that no longer works
      with the inline function. In order to avoid a regression, we
      have to also remove the #ifdef from decnet in the same patch.

      ASoC: Add info callback for SX_TLV controls

      SX_TLV controls are intended for situations where the register behind
      the control has some non-zero value indicating the minimum gain
      and then gains increasing from there and eventually overflowing through
      zero.

      Currently every CODEC implementing these controls specifies the minimum
      as the non-zero value for the minimum and the maximum as the number of
      gain settings available.

      This means when the info callback subtracts the minimum value from the
      maximum value to calculate the number of gain levels available it is
      actually under reporting the available levels. This patch fixes this
      issue by adding a new snd_soc_info_volsw_sx callback that does not
      subtract the minimum value.

      rbd: use writefull op for object size writes

      This covers only the simplest case - an object size sized write, but
      it's still useful in tiering setups when EC is used for the base tier
      as writefull op can be proxied, saving an object promotion.

      Even though updating ceph_osdc_new_request() to allow writefull should
      just be a matter of fixing an assert, I didn't do it because its only
      user is cephfs.  All other sites were updated.

      Reflects ceph.git commit 7bfb7f9025a8ee0d2305f49bf0336d2424da5b5b.

      rbd: set max_sectors explicitly

      Commit 30e2bc08b2bb ("Revert "block: remove artifical max_hw_sectors
      cap"") restored a clamp on max_sectors.  It's now 2560 sectors instead
      of 1024, but it's not good enough: we set max_hw_sectors to rbd object
      size because we don't want object sized I/Os to be split, and the
      default object size is 4M.

      So, set max_sectors to max_hw_sectors in rbd at queue init time.

      x86/ioapic: Disable interrupts when re-routing legacy IRQs

      A sporadic hang with consequent crash is observed when booting Hyper-V 
Gen1
      guests:

      The issue is easily reproducible with a simple instrumentation: if
      mdelay(10) is put between mp_setup_entry() and mp_register_handler() calls
      in mp_irqdomain_alloc() Hyper-V guest always fails to boot when re-routing
      IRQ0. The issue seems to be caused by the fact that we don't disable
      interrupts while doing IOPIC programming for legacy IRQs and IRQ0 actually
      happens.

      Protect the setup sequence against concurrent interrupts.

      [ tglx: Make the protection unconditional and not only for legacy
                interrupts ]

      Spectrum ASIC, including L2 bridge forwarding offload.

      The only non-mlxsw patch in this patchset is the first one, introducing
      pre-change upper notifier. That is used in last patch to ensure ports of
      single ASIC are not bridged into multiple bridges, as that scenario is
      currently not supported by driver.

      In the newly introduced Spectrum switch ASIC, packets destined to not
      offloaded netdevs will be classified to special FIDs (vFIDs) in the
      device and flooded to the CPU port.

      The flooding table used is of type per-FID, which allows one to create
      different flooding domains for different vFIDs.

      While using a simple single-entry flood table is certainly sufficient at
      this point, we do plan to offload 802.1D bridges involving VLAN
      interfaces, thus making this change necessary.

      timekeeping: Increment clock_was_set_seq in timekeeping_init()

      timekeeping_init() can set the wall time offset, so we need to
      increment the clock_was_set_seq counter. That way hrtimers will pick
      up the early offset immediately. Otherwise on a machine which does not
      set wall time later in the boot process the hrtimer offset is stale at
      0 and wall time timers are going to expire with a delay of 45 years.

      Intel Wired LAN Driver Updates 2015-10-16

      This series contains updates to e1000, e1000e, igb, igbvf, ixgbe, ixgbevf,
      i40e, i40evf and fm10k.

      Alex Duyck fixes the polling routine for i40e/i40evf were the NAPI budget
      for receive cleanup was being rounded up to 1 but the netpoll call was
      expecting no Rx to be processed as the budget passed was 0.  Also cleaned
      up IN_NETPOLL flag that was not adding any value due to the receive
      cleanup was handled in NAPI.  Added support for netpoll for i40evf as
      well.

      Jesse updates all of our drivers to use napi_complete_done() instead of
      napi_complete(), which allows us to use
      /sys/class/net/ethX/gro_flush_timeout.  Added ethtool support to control
      and report the new Interrupt Limit register, since the XL710 hardware
      has a different interrupt moderation design that can support a limit of
      total interrupts per second per vector.

      Shannon cleans up startup log entries to cut down the number by putting
      a couple behind debug flags and combining others into single line.  Added
      support to enable/disable printing VEB statistics via ethtool.

      Jingjing fixes a compile issue by adding const to functions that return
      strings that are not going to be modified.

      Greg Rose cleans up defines that were not used and were causing customer
      confusion.

      Greg Bowers adds support for setting a new bit in the Set Local LLDP MIB
      admin queue command Type field.

      Mitch fixes an issue where vlan_features field was set to the same value
      as netdev features field, but before the features were actually being
      set up, leaving the vlan_features empty.  Resolve the issue by setting
      up the netdev features first, then mask out the VLAN feature bits when
      assigning vlan_features.  Fixed VF init timing, where in some instances
      the VFs would fail to initialize the first time you loaded the driver.
      To correct this, increased the delay time for the init task and wait
      longer before giving up.

      v2: fix missing space in function header comment in patch 3, based on
          feedback from Sergei Shtylyov.

      ath10k: configure copy engine 5 for HTT messages

      Currently target to host (T2H) HTT messages are received at copy engine 1.
      These messages are processed by HTC layer in both host and target.
      To avoid HTC level processing overhead in both host and target,
      the unused copy engine 5 is being used for receiving HTT T2H messages.
      This will speedup the receive data processing as well as htt tx 
completion.
      Hence host and target copy engine configuration tables are updated
      to enable CE5 pipe. The in-direction HTT mapping is now pointing to CE5
      for all HTT T2H.

      Moreover HTT send completion messages are polled from HTC handler
      as CE 4 is not interrupt-driven. For faster tx completion, CE4 polling
      needs to be done whenever CE pipe which transports HTT Rx (target->host)
      is processed. This avoids overhead of polling HTT messages from HTC
      layer. Servicing CE 4 faster is helping to solve "failed to transmit
      packet, dropping: -105".

      PCI/MSI: Allow the MSI domain to be device-specific

      So far, we've always considered that for a given PCI device, its
      MSI controller was either set by the architecture-specific
      pcibios hook, or simply inherited from the host bridge.

      This doesn't cover things like firmware-defined topologies like
      msi-map (DT) or IORT (ACPI), which can provide information about
      which MSI controller to use on a per-device basis.

      This patch adds the necessary hook into the MSI code to allow this
      feature, and provides the msi-map functionnality as a first
      implementation.

      PCI: Add per-device MSI domain hook

      So far, we have considered that the MSI domain for a device was
      either set via the architecture-dependent pcibios implementation
      or inherited from the host bridge.

      As we're about to break that assumption, add pci_dev_msi_domain
      which is the equivalent of pci_host_bridge_msi_domain, but for
      a single device.

      Other than moving things around a bit, this patch on its own
      has no effect.

      of/irq: Use the msi-map property to provide device-specific MSI domain

      While msi-parent is used to point to the MSI controller that
      works for all the devices behind a root complex, it doesn't
      allow configurations where each individual device can be routed
      to a separate MSI controller.

      The msi-map property provides this flexibility (and much more),
      so let's add a utility function that parses it, and return the
      corresponding MSI domain.

      of/irq: Add support code for multi-parent version of "msi-parent"

      Since 126b16e2ad98 ("Docs: dt: add generic MSI bindings"),
      the definition of "msi-parent" has evolved, while maintaining
      some degree of compatibility. It can now express multiple MSI
      controllers as parents, as well as some sideband data being
      communicated to the controller.

      This patch adds the parsing of the property, iterating over
      the multiple parents until a suitable irqdomain is found.
      It can also fallback to the original parsing if the old
      binding is detected.

      This support code gets used in the subsequent patches.

      i40e: increase AQ work limit

      With 64 VFs, we can easily overwhelm the AQ on the PF if we have too low
      a limit on the number of AQ requests. This leads to ARQ overflow errors,
      and occasionally VFs that fail to initialize.

      Since we really only hit this condition on initial VF driver load, the
      requests that we process are lightweight, so this extra work doesn't
      cause problems for the PF driver.

      i40evf: relax and stagger init timing a bit

      On some devices, in some systems, in some configurations, the VFs would
      fail to initialize the first time you loaded the driver.

      To correct this, increase the delay time for the init task slightly, and
      wait longer before giving up.

      If we enable VFs and load the VF driver in the same kernel as the PF
      driver, we can totally overwhelm the PF driver with AQ requests because
      all of the instances try to initialize at the same time.

      To help alleviate this, stagger the initial scheduling of the init task
      using the PCIe function as a multiplier. We mask off the function to
      only three bits so no instance has to wait too long.

      With these two changes, initializing 128 VFs on a single device goes
      from four minutes to just a few seconds.

      i40evf: correctly populate vlan_features

      The vlan_features field was correctly being set to the same value as the
      netdev features field. However, this was being done before the features
      were actually being set up, leaving the vlan_features empty.

      Also, after a reset, vlan_features will be incorrectly assigned the
      previous netdev feature flags, which can contain VLAN feature bits. This
      makes the VLAN code angry and will cause a stack dump.

      To fix these issues, set up the netdev features first, then mask out the
      VLAN feature bits when assigning vlan_features.

      i40e: reset the invalid msg counter in vf when a valid msg is received

      When the number of invalid messages from a VF is exceeded, the VF
      will be disabled, due to the invalid messages.  This happens if
      other VF drivers (like DPDK) send a message through the driver's
      mailbox (aka virtchannel) interface, but the message is not
      supported by the i40e pf driver, such as CONFIG_PROMISCUOUS_MODE.

      This patch changes the num_invalid_msgs in struct i40e_vf to record
      the continuous invalid msgs, and it will be reset when a valid msg
      is received.

      i40e/i40evf: moderate interrupts differently

      The XL710 hardware has a different interrupt moderation design
      that can support a limit of total interrupts per second per
      vector, in addition to the "number of interrupts per second"
      controls already established in the driver.  This combination
      of hardware features allows us to set very low default latency
      settings but minimize the total CPU utilization by not
      making too many interrupts, should the user desire.

      The current driver implementation is still enabling the dynamic
      moderation in the driver, and only using the rx/tx-usecs
      limit in ethtool to limit the interrupt rate per second, by default.

      The new code implemented in this patch
      2) adds init/use of the new "Interrupt Limit" register
      3) adds ethtool knob to control/report the limits above

      Usage is ethtool -C ethx rx-usecs-high <value> Where <value> is number
      of microseconds to create a rate of 1/N interrupts per second,
      regardless of rx-usecs or tx-usecs values. Since there is a credit based
      scheme in the hardware, the rx-usecs and tx-usecs can be configured for
      very low latency for short bursts, but once the credit runs out the
      refill rate on the credits is limited by rx-usecs-high.

      Allow the nvmupdate application to decide when a read or write error
      should be exposed to the user.  Since the application needs to use
      write probes to find the ReadOnly sections on a potentially unknown NVM
      version in the HW and read probes to check the status of the last write,
      some error messages are expected, but need not be shown to the users.
      The driver doesn't know which are ignorable from real errors, so needs
      to let the application make the decision.

      The code in i40e and i40evf is using an "IN_NETPOLL" flag that has never

      As such the flag was set, the queue was scheduled via NAPI, and then 
polled
      from the netpoll controller and if any Rx packets were processed the were
      processed in the wrong context.

      In addition the flag itself just added an unneeded conditional to the
      hot-path so it can safely be dropped and save us a few instructions.

      Docs: dt: Add PCI MSI map bindings

      Currently msi-parent is used by a few bindings to describe the
      relationship between a PCI root complex and a single MSI controller, but
      this property does not have a generic binding document.

      Additionally, msi-parent is insufficient to describe more complex
      relationships between MSI controllers and devices under a root complex,
      where devices may be able to target multiple MSI controllers, or where
      MSI controllers use (non-probeable) sideband information to distinguish
      devices.

      This patch adds a generic binding for mapping PCI devices to MSI
      controllers. This document covers msi-parent, and a new msi-map property
      (specific to PCI*) which may be used to map devices (identified by their
      Requester ID) to sideband data for each MSI controller that they may
      target.

      genirq/msi: Do not use pci_msi_[un]mask_irq as default methods

      When we create a generic MSI domain, that MSI_FLAG_USE_DEF_CHIP_OPS
      is set, and that any of .mask or .unmask are NULL in the irq_chip
      structure, we set them to pci_msi_[un]mask_irq.

      This is a bad idea for at least two reasons:
      - PCI_MSI might not be selected, kernel fails to build (yes, this is
        legitimate, at least on arm64!)
      - This may not be a PCI/MSI domain at all (platform MSI, for example)

      Either way, this looks wrong. Move the overriding of mask/unmask to
      the PCI counterpart, and panic is any of these two methods is not
      set in the core code (they really should be present).

      On 32-bit systems, the initial_page_table is reused by
      efi_call_phys_prolog as an identity map to call
      SetVirtualAddressMap.  efi_call_phys_prolog takes care of
      converting the current CPU's GDT to a physical address too.

      For PAE kernels the identity mapping is achieved by aliasing the
      first PDPE for the kernel memory mapping into the first PDPE
      of initial_page_table.  This makes the EFI stub's trick "just work".

      However, for non-PAE kernels there is no guarantee that the identity
      mapping in the initial_page_table extends as far as the GDT; in this
      case, accesses to the GDT will cause a page fault (which quickly becomes
      a triple fault).  Fix this by copying the kernel mappings from
      swapper_pg_dir to initial_page_table twice, both at PAGE_OFFSET and at
      identity mapping.

      For some reason, this is only reproducible with QEMU's dynamic translation
      mode, and not for example with KVM.  However, even under KVM one can 
clearly
      see that the page table is bogus:

          $ qemu-system-i386 -pflash OVMF.fd -M q35 vmlinuz0 -s -S -daemonize
          $ gdb
          (gdb) target remote localhost:1234
          (gdb) hb *0x02858f6f
          Hardware assisted breakpoint 1 at 0x2858f6f
          (gdb) c
          Continuing.

          Breakpoint 1, 0x02858f6f in ?? ()
          (gdb) monitor info registers
          ...
          GDT=     0724e000 000000ff
          IDT=     fffbb000 000007ff
          CR0=0005003b CR2=ff896000 CR3=032b7000 CR4=00000690
          ...

      The page directory is sane:

          (gdb) x/4wx 0x32b7000
          0x32b7000:    0x03398063      0x03399063      0x0339a063

0x00403003

      but our particular page directory entry is empty:

          (gdb) x/1wx 0x32b7000 + (0x724e000 >> 22) * 4
          0x32b7070:    0x00000000

      [ It appears that you can skate past this issue if you don't receive
        any interrupts while the bogus GDT pointer is loaded, or if you avoid
        reloading the segment registers in general.

        Andy Lutomirski provides some additional insight:

         "AFAICT it's entirely permissible for the GDTR and/or LDT
          descriptor to point to unmapped memory.  Any attempt to use them
          (segment loads, interrupts, IRET, etc) will try to access that memory
          as if the access came from CPL 0 and, if the access fails, will
          generate a valid page fault with CR2 pointing into the GDT or
          LDT."

        Up until commit 23a0d4e8fa6d ("efi: Disable interrupts around EFI
        calls, not in the epilog/prolog calls") interrupts were disabled
        around the prolog and epilog calls, and the functional GDT was
        re-installed before interrupts were re-enabled.

        Which explains why no one has hit this issue until now. ]

      via-rhine: fix VLAN receive handling regression.

      Because eth_type_trans() consumes ethernet header worth of bytes, a call
      to read TCI from end of packet using rhine_rx_vlan_tag() no longer works
      as it's reading from an invalid offset.

      Tested to be working on PCEngines Alix board.

      Revert "inet: fix double request socket freeing"

      This reverts commit c69736696cf3742b37d850289dc0d7ead177bb14.

      At the time of above commit, tcp_req_err() and dccp_req_err()
      were dead code, as SYN_RECV request sockets were not yet in ehash table.

      Real bug was fixed later in a different commit.

      We need to revert to not leak a refcount on request socket.

      inet_csk_reqsk_queue_drop_and_put() will be added
      in following commit to make clean inet_csk_reqsk_queue_drop()
      does not release the reference owned by caller.

(78f7f1e54b).

      The new header files and their meaning are:

      asm/fpu/types.h:
        FPU related data types, needed for 'struct thread_struct' and
        'struct task_struct'.

      asm/fpu/api.h:
        FPU related 'public' functions for other subsystems and device
        drivers.

      ipv6: Initialize rt6_info properly in ip6_blackhole_route()

      ip6_blackhole_route() does not initialize the newly allocated
      rt6_info properly.  This patch:
      1. Call rt6_info_init() to initialize rt6i_siblings and rt6i_uncached

      2. The current rt->dst._metrics init code is incorrect:
         - 'rt->dst._metrics = ort->dst._metris' is not always safe
         - Not sure what dst_copy_metrics() is trying to do here
           considering ip6_rt_blackhole_cow_metrics() always returns
           NULL

         Fix:
         - Always do dst_copy_metrics()
         - Replace ip6_rt_blackhole_cow_metrics() with
           dst_cow_metrics_generic()

      3. Mask out the RTF_PCPU bit from the newly allocated blackhole route.
         This bug triggers an oops (reported by Phil Sutter) in 
rt6_get_cookie().
         It is because RTF_PCPU is set while rt->dst.from is NULL.

      Bluetooth: Fix LE reconnection logic

      We can't use hci_explicit_connect_lookup() since that would only cover
      explicit connections, leaving normal reconnections completely
      untouched. Not using it in turn means leaving out entries in
      pend_le_reports.

      To fix this and simplify the logic move conn params from the reports
      list to the pend_le_conns list for the duration of an explicit
      connect. Once the connect is complete move the params back to the
      pend_le_reports list. This also means that the explicit connect lookup
      function only needs to look into the pend_le_conns list.

      Bluetooth: Fix reference counting for LE-scan based connections

      The code should never directly call hci_conn_hash_del since many
      cleanup & reference counting updates would be lost. Normally
      hci_conn_del is the right thing to do, but in the case of a connection
      doing LE scanning this could cause a deadlock due to doing a
      cancel_delayed_work_sync() on the same work callback that we were
      called from.

      Connections in the LE scanning state actually need very little cleanup
      - just a small subset of hci_conn_del. To solve the issue, refactor
      out these essential pieces into a new hci_conn_cleanup() function and
      call that from the two necessary places.

      Bluetooth: Fix double scan updates

      When disable/enable scan command is issued twice, some controllers
      will return an error for the second request, i.e. requests with this
      command will fail on some controllers, and succeed on others.

      This patch makes sure that unnecessary scan disable/enable commands
      are not issued.

      When adding device to the auto connect whitelist when there is pending
      connect attempt, there is no need to update scan.

      hci_connect_le_scan_cleanup is conditionally executing
      hci_conn_params_del, that is calling hci_update_background_scan. Make
      the other case also update scan, and remove reduntand call from
      hci_connect_le_scan_remove.

      When stopping interleaved discovery the state should be set to stopped
      only when both LE scanning and discovery has stopped.

      tipc: update node FSM when peer RESET message is received

      The change made in the previous commit revealed a small flaw in the way
      the node FSM is updated. When the function tipc_node_link_down() is
      called for the last link to a node, we should check whether this was
      caused by a local reset or by a received RESET message from the peer.
      In the latter case, we can directly issue a PEER_LOST_CONTACT_EVT to
      the node FSM, so that it is ready to re-establish contact. If this is
      not done, the peer node will sometimes have to go through a second
      establish cycle before the link becomes stable.

      We fix this in this commit by conditionally issuing the mentioned
      event in the function tipc_node_link_down(). We also move LINK_RESET
      FSM even away from the link_reset() function and into the caller
      function, partially because it is easier to follow the code when state
      changes are gathered at a limited number of locations, partially
      because there will be cases in future commits where we don't want the
      link to go RESET mode when link_reset() is called.

      tipc: send out RESET immediately when link goes down

      When a link is taken down because of a node local event, such as
      disabling of a bearer or an interface, we currently leave it to the
      peer node to discover the broken communication. The default time for
      such failure discovery is 1.5-2 seconds.

      If we instead allow the terminating link endpoint to send out a RESET
      message at the moment it is reset, we can achieve the impression that
      both endpoints are going down instantly. Since this is a very common
      scenario, we find it worthwhile to make this small modification.

      Apart from letting the link produce the said message, we also have to
      ensure that the interface is able to transmit it before TIPC is
      detached. We do this by performing the disabling of a bearer in three
      steps:

      1) Disable reception of TIPC packets from the interface in question.
      2) Take down the links, while allowing them so send out a RESET message.
      3) Disable transmission of TIPC packets on the interface.

      Apart from this, we now have to react on the NETDEV_GOING_DOWN event,
      instead of as currently the NEDEV_DOWN event, to ensure that such
      transmission is possible during the teardown phase.

      tipc: delay ESTABLISH state event when link is established

      Link establishing, just like link teardown, is a non-atomic action, in
      the sense that discovering that conditions are right to establish a link,
      and the actual adding of the link to one of the node's send slots is done
      in two different lock contexts. The link FSM is designed to help bridging
      the gap between the two contexts in a safe manner.

      We have now discovered a weakness in the implementaton of this FSM.
      Because we directly let the link go from state LINK_ESTABLISHING to
      state LINK_ESTABLISHED already in the first lock context, we are unable
      to distinguish between a fully established link, i.e., a link that has
      been added to its slot, and a link that has not yet reached the second
      lock context. It may hence happen that a manual intervention, e.g., when
      disabling an interface, causes the function tipc_node_link_down() to try
      removing the link from the node slots, decrementing its active link
      counter etc, although the link was never added there in the first place.

      We solve this by delaying the actual state change until we reach the
      second lock context, inside the function tipc_node_link_up(). This
      makes it possible for potentail callers of __tipc_node_link_down() to
      know if they should proceed or not, and the problem is solved.

      Unforunately, the situation described above also has a second problem.
      Since there by necessity is a tipc_node_link_up() call pending once
      the node lock has been released, we must defuse that call by setting
      the link back from LINK_ESTABLISHING to LINK_RESET state. This forces
      us to make a slight modification to the link FSM, which will now look
      as follows.

      tipc: disallow packet duplicates in link deferred queue

      After the previous commits, we are guaranteed that no packets
      of type LINK_PROTOCOL or with illegal sequence numbers will be
      attempted added to the link deferred queue. This makes it possible to
      make some simplifications to the sorting algorithm in the function
      tipc_skb_queue_sorted().

      We also alter the function so that it will drop packets if one with
      the same seqeunce number is already present in the queue. This is
      necessary because we have identified weird packet sequences, involving
      duplicate packets, where a legitimate in-sequence packet may advance to
      the head of the queue without being detected and de-queued.

      Finally, we make this function outline, since it will now be called only
      in exceptional cases.

      tipc: improve sequence number checking

      The sequence number of an incoming packet is currently only checked
      for less than, equality to, or bigger than the next expected number,
      meaning that the receive window in practice becomes one half sequence
      number cycle, or U16_MAX/2. This does not make sense, and may not even
      be safe if there are extreme delays in the network. Any packet sent by
      the peer during the ongoing cycle must belong inside his current send
      window, or should otherwise be dropped if possible.

      Since a link endpoint cannot know its peer's current send window, it
      has to base this sanity check on a worst-case assumption, i.e., that
      the peer is using a maximum sized window of 8191 packets. Using this
      assumption, we now add a check that the sequence number is not bigger
      than next_expected + TIPC_MAX_LINK_WIN. We also re-order the checks
      done, so that the receive window test is performed before the gap test.
      This way, we are guaranteed that no packet with illegal sequence numbers
      are ever added to the deferred queue.

      tipc: simplify tipc_link_rcv() reception loop

      Currently, all packets received in tipc_link_rcv() are unconditionally
      added to the packet deferred queue, whereafter that queue is walked and
      all its buffers evaluated for delivery. This is both non-optimal and
      and makes the queue sorting function unnecessary complex.

      This commit changes the loop so that an arrived packet is evaluated
      first, and added to the deferred queue only when a sequence number gap
      is discovered. A non-empty deferred queue is walked until it is empty
      or until its head's sequence number doesn't fit.

      tipc: limit usage of temporary skb list during packet reception

      During packet reception, the function tipc_link_rcv() adds its accepted
      packets to a temporary buffer queue, before finally splicing this queue
      into the lock protected input queue that will be delivered up to the
      socket layer. The purpose is to reduce potential contention on the input
      queue lock. However, since the vast majority of packets arrive in
      sequence, they will anyway be added one by one to the input queue, and
      the use of the temporary queue becomes a sub-optimization.

      The only case where this queue makes sense is when unpacking buffers
      from a bundle packet; here we want to avoid dozens of small buffers
      to be added individually to the lock-protected input queue in a tight
      loop.

      In this commit, we remove the general usage of the temporary queue,
      and keep it only for the packet unbundling case.

      bonding: support encapsulated ipv6 TSO

      If using a sixtofour device on top of a bonding device,
      skb segmentation of TCP traffic is done right before calling
      bonding xmit, because bonding only enables TSO for IPv4.

      This patch improves single flow performance by about 120 % on my hosts,
      because segmentation is deferred right before calling slave xmit.

      mlxsw: Add trap group for control packets

      Previously, we trapped flooded and control packets using the same trap
      group. This can cause flooded packets to overflow the PCI bus and
      prevent control packets (e.g. STP, LACP) from getting to the CPU.

      Solve this by splitting the RX trap group to RX and control, which allows
      us to configure a policer on the first, thereby preventing it from
      overflowing the PCI bus.

      Instead of passing both the trap group and ID for the function that

      This is a workaround for KNL platform, where in some cases MPERF counter
      will not have updated value before next read of MSR_IA32_MPERF. In this
      case divide by zero will occur. This change ignores current sample for

       "We have four batched up patches for the current rc kernel.

        Two of them are small fixes that are obvious.

        One of them is larger than I would like for a late stage rc pull, but
        we found an issue in the namespace lookup code related to RoCE and
        this works around the issue for now (we allow a lookup with a
        namespace to succeed on RoCE since RoCE namespaces aren't implemented
        yet).  This will go away in 4.4 when we put in support for namespaces
        in RoCE devices.

        The last one is large in terms of lines, but is all legal and no
        functional changes.  Cisco needed to update their files to be more
        specific about their license.  They had intended the files to be dual
        licensed as GPL/BSD all along, and specified that in their module
        license tag, but their file headers were not up to par.  They
        contacted all of the contributors to get agreement and then submitted
        a patch to update the license headers in the files.

        Summary:

         - Work around connection namespace lookup bug related to RoCE

         - Change usnic license to Dual GPL/BSD (was intended to be that way
           all along, but wasn't clear, permission from contributors was

      vmstat: explicitly schedule per-cpu work on the CPU we need it to run on

      The vmstat code uses "schedule_delayed_work_on()" to do the initial
      startup of the delayed work on the right CPU, but then once it was
      started it would use the non-cpu-specific "schedule_delayed_work()" to
      re-schedule it on that CPU.

      That just happened to schedule it on the same CPU historically (well, in
      almost all situations), but the code _requires_ this work to be per-cpu,
      and should say so explicitly rather than depend on the non-cpu-specific
      scheduling to schedule on the current CPU.

      The timer code is being changed to not be as single-minded in always
      running things on the calling CPU.

      See also commit 874bbfe600a6 ("workqueue: make sure delayed work run in
      local cpu") that for now maintains the local CPU guarantees just in case
      there are other broken users that depended on the accidental behavior.

      KEYS: Fix crash when attempt to garbage collect an uninstantiated keyring

      The following sequence of commands:

          i=`keyctl add user a a @s`
          keyctl request2 keyring foo bar @t
          keyctl unlink $i @s

      tries to invoke an upcall to instantiate a keyring if one doesn't already
      exist by that name within the user's keyring set.  However, if the upcall
      fails, the code sets keyring->type_data.reject_error to -ENOKEY or some
      other error code.  When the key is garbage collected, the key destroy
      function is called unconditionally and keyring_destroy() uses list_empty()
      on keyring->type_data.link - which is in a union with reject_error.
      Subsequently, the kernel tries to unlink the keyring from the keyring 
names
      list - which oopses like this:

      gpio: pl061: assign the apropriate handler for irqs

      The PL061 can handle level IRQs and edge IRQs, however it is
      just utilizing handle_simple_irq() for all IRQs. Inspired by
      Stefan Agners patch to vf610, this assigns the right handler
      depending on what type is set up, and after this
      handle_bad_irq() is only used as default and if the type is
      not specified, as is done in the OMAP driver: defining the
      IRQ type is really not optional for this driver.

      The interrupt handler was just writing the interrupt clearing
      register for all lines that were high when entering the handling
      loop, this is wrong: that register is only supposed to be
      written (on a per-line basis) for edge IRQs, so this ACK
      was moved to the .irq_ack() callback as is proper.

      Tested with PL061 on the ARM RealView PB11MPCore and the
      MMC/SC card detect GPIO.

      ARM: tegra: Comment out gpio-ranges properties

      While the addition of these properties is technically correct it unveils
      a bug with deferred probe. The problem is that the presence of the gpio-
      range property causes the gpio-tegra driver to defer probe (it needs the
      pinctrl driver to be ready). That's technically correct, but it causes a
      couple of issues:

        - The keyboard on Chromebooks stops working. The reason for that is
          that the gpio-tegra device has not registered an IRQ domain by the
          time the EC SPI device is registered, hence the interrupt number
          resolves to 0. This is technically a bug in the SPI core, since it
          should really resolve the interrupt at probe time and defer if the
          IRQ domain isn't available yet. This is similar to what's done for
          I2C and platform device already.

        - The gpio-tegra device deferring probe means that it is moved to the
          end of the dpm_list. This list defines the suspend/resume order for
          devices. However the core lacks a way to move all users of the
          gpio-tegra device to the end of the dpm_list at the same time. This
          in turn results in a subtle bug on Jetson TK1, where the gpio-keys
          device is used to expose the power key as input. The power key is a
          convenient way to wake the system from suspend. Interestingly, the
          gpio-keys device ends up getting probed at a point after gpio-tegra
          has been probed successfully from having been deferred earlier. As
          such the driver doesn't need to defer the probe itself, and hence
          the device isn't moved to the end of the dpm_list. This causes the
          gpio-tegra device to be suspended before gpio-keys, which in turn
          leaves gpio-keys unable to wake the system from suspend.

      There are patches in the works to fix both of the above issues, but they
      are too involved to make it into v4.3, so in the meantime let's fix the
      regressions by commenting out the gpio-ranges properties until the fixes
      have landed.

      block: don't release bdi while request_queue has live references

      bdi's are initialized in two steps, bdi_init() and bdi_register(), but
      destroyed in a single step by bdi_destroy() which, for a bdi embedded
      in a request_queue, is called during blk_cleanup_queue() which makes
      the queue invisible and starts the draining of remaining usages.

      A request_queue's user can access the congestion state of the embedded
      bdi as long as it holds a reference to the queue.  As such, it may
      access the congested state of a queue which finished
      blk_cleanup_queue() but hasn't reached blk_release_queue() yet.
      Because the congested state was embedded in backing_dev_info which in
      turn is embedded in request_queue, accessing the congested state after
      bdi_destroy() was called was fine.  The bdi was destroyed but the
      memory region for the congested state remained accessible till the
      queue got released.

      a13f35e87140 ("writeback: don't embed root bdi_writeback_congested in
      bdi_writeback") changed the situation.  Now, the root congested state
      which is expected to be pinned while request_queue remains accessible
      is separately reference counted and the base ref is put during
      bdi_destroy().  This means that the root congested state may go away
      prematurely while the queue is between bdi_dstroy() and
      blk_cleanup_queue(), which was detected by Andrey's KASAN tests.

      The root cause of this problem is that bdi doesn't distinguish the two
      steps of destruction, unregistration and release, and now the root
      congested state actually requires a separate release step.  To fix the
      issue, this patch separates out bdi_unregister() and bdi_exit() from
      bdi_destroy().  bdi_unregister() is called from blk_cleanup_queue()
      and bdi_exit() from blk_release_queue().  bdi_destroy() is now just a
      simple wrapper calling the two steps back-to-back.

      While at it, the prototype of bdi_destroy() is moved right below
      bdi_setup_and_register() so that the counterpart operations are
      located together.

      clocksource/drivers/exynos_mct: Use container_of() instead of 
this_cpu_ptr()

      Since evt structure is embedded in per-CPU mevt structure it's
      definitely faster to use container_of() to get access to mevt
      if we have evt (for example as incoming function argument) instead
      of more expensive approach with this_cpu_ptr(&percpu_mct_tick).
      this_cpu_ptr() on per-CPU mevt structure leads to access to cp15
      to get cpu id and arithmetic operations.
      Container_of() is cheaper since it's just one asm instruction.
      This should work if used evt pointer is correct and owned by
      local mevt structure.

      For example, before this patch set_state_shutdown() looks like:

       4a4:     e92d4010        push    {r4, lr}

      Merge branch 'switchdev-locking'

      Jiri Pirko says:

      ====================
      switchdev: change locking

      This is something which I'm currently struggling with.
      Callers of attr_set and obj_add/del often hold not only RTNL, but also
      spinlock (bridge). So in that case, the driver implementing the op cannot 
sleep.

      The way rocker is dealing with this now is just to invoke driver operation
      and go out, without any checking or reporting of the operation status.

      Since it would be nice to at least put a warning in case the operation 
fails,
      it makes sense to do this in delayed work directly in switchdev core
      instead of implementing this in separate drivers. And that is what this 
patchset
      is introducing.

      So from now on, the locking of switchdev mod ops is consistent. Caller 
either
      holds rtnl mutex or in case it does not, caller sets defer flag, telling
      switchdev core to process the op later, in deferred queue.

      Function to force to process switchdev deferred ops can be called by op
      caller in appropriate location, for example after it releases
      spin lock, to force switchdev core to process pending ops.

      v1->v2:
      - rebased on current net-next head (including Scott's ageing patchset)
      v2->v3:
      - fixed comment s/of/or/ typo suggested by Nik
      v3->v4:
      - the actual patchset is sent instead of different branch I send in v3 :/
      v4->v5:
      - added patch to "const" attr param
      - reworked deferred ops infrastructure (mainly patch number 1 and
        internal users (patch 3 and 5)) - resolves the issue pointed out
        by John

      switchdev: introduce possibility to defer obj_add/del

      Similar to the attr usecase, the caller knows if he is holding RTNL and is
      in atomic section. So let the called to decide the correct call variant.

      This allows drivers to sleep inside their ops and wait for hw to get the
      operation status. Then the status is propagated into switchdev core.
      This avoids silent errors in drivers.

      switchdev: allow caller to explicitly request attr_set as deferred

      Caller should know if he can call attr_set directly (when holding RTNL)
      or if he has to defer the att_set processing for later.

      This also allows drivers to sleep inside attr_set and report operation
      status back to switchdev core. Switchdev core then warns if status is
      not ok, instead of silent errors happening in drivers.

      Benefit from newly introduced switchdev deferred ops infrastructure.

      crypto: keywrap - add key wrapping block chaining mode

      This patch implements the AES key wrapping as specified in
      NIST SP800-38F and RFC3394.

      The implementation covers key wrapping without padding.

      IV handling: The caller does not provide an IV for encryption,
      but must obtain the IV after encryption which would serve as the first
      semblock in the ciphertext structure defined by SP800-38F. Conversely,
      for decryption, the caller must provide the first semiblock of the data
      as the IV and the following blocks as ciphertext.

      The key wrapping is an authenticated decryption operation. The caller
      will receive EBADMSG during decryption if the authentication failed.

      Albeit the standards define the key wrapping for AES only, the template
      can be used with any other block cipher that has a block size of 16
      bytes. During initialization of the template, that condition is checked.
      Any cipher not having a block size of 16 bytes will cause the
      initialization to fail.

      Intel Wired LAN Driver Updates 2015-10-15

      This series contains updates to i40e, i40evf and ixgbe.

      Emil changes the ixgbe driver to disable LRO by default in favor or GRO.

      Mark provides two changes for ixgbe, first fixes a semaphore issue when
      a reset never completes, it is necessary to retake the semaphore before
      returning.

      Jesse fixes up a missing function header comment variable reference.  Then
      enables ethtool priv flags to control flow director at runtime.

      Neerav changes several i40e error messages to debug only since the
      messages were printing when there was no functional issue and were meant
      for debug only.

      Catherine changes the i40e driver to make only X722 support 100M SGMII,
      since it is the only device to actually support it.

      Anjali modifies the i40e/i40evf driver to add writeback on ITR offload
      support for X722 since the device has a way to work around the
      descriptor writeback issue.

      Mitch cleans up obsolete code.  Also reduces the i40evf init time by
      shortening up the delays in the init task to aid in performance in
      load/unload tests and mitigates DMAR errors in VF enable/disable tests.

      Shannon modifies i40e to allow flow director sideband when the device
      is in MFP mode and only has one partition enabled, since we still have
      plenty of interrupts for managing the flow director activity.  Also
      cleaned up flow director ATR control in debugfs since the priv flag
      has been added to our ethtool interface.  Makes several general code
      cleanups of redundant or unnecessary code for i40e.

      posix_cpu_timer: Reduce unnecessary sighand lock contention

      It was found while running a database workload on large systems that
      significant time was spent trying to acquire the sighand lock.

      The issue was that whenever an itimer expired, many threads ended up
      simultaneously trying to send the signal. Most of the time, nothing
      happened after acquiring the sighand lock because another thread
      had just already sent the signal and updated the "next expire" time.
      The fastpath_timer_check() didn't help much since the "next expire"
      time was updated after the threads exit fastpath_timer_check().

      This patch addresses this by having the thread_group_cputimer structure
      maintain a boolean to signify when a thread in the group is already
      checking for process wide timers, and adds extra logic in the fastpath
      to check the boolean.

      posix_cpu_timer: Check thread timers only when there are active thread 
timers

      The fastpath_timer_check() contains logic to check for if any timers
      are set by checking if !task_cputime_zero(). Similarly, we can do this
      before calling check_thread_timers(). In the case where there
      are only process-wide timers, this will skip all of the computations for
      per-thread timers when there are no per-thread timers.

      As suggested by George, we can put the task_cputime_zero() check in
      check_thread_timers(), since that is more of an optization to the
      function. Similarly, we move the existing check of cputimer->running
      to check_process_timers().

      mitigates DMAR errors in VF enable/disable tests with absurdly short
      delays. In the real world, the VF driver will come up more quickly.

      The original values were set conservatively based on what we expected
      from the firmware in terms of performance. Now that the driver is in use
      and we know how well firmware responds to our requests, we can shorten
      these delays.

      s390/dasd: fix list_del corruption after lcu changes

      A summary unit check occurs when the lcu updates the PAV configuration
      e.g. base PAV assignment or PAV mode at all. This requires the reset
      of the drivers internal pavgroups. Therefore the alias devices are
      flushed and moved via a temporary list to the active_devices list
      where they are not associated with a pavgroup. In conjunction with
      updates to the base device the pavgroup may be removed since both
      base_list and alias_list are empty. Unfortunately during alias flush
      and move to the active_device list from alias_list the pavgroup
      pointer is not deleted in the device private structure. This leads to
      a list del_corruption if another lcu_update tries to move the device
      in the non existent pavgroup.

      Fix by removing the pavgroup pointer after the alias device was moved
      to the active_devices list.

      netfilter: nfnetlink_log: consolidate check for instance in 
nfulnl_recv_config()

      This patch consolidates the check for valid logger instance once we have
      passed the command handling:

      The config message that we receive may contain the following info:

      1) Command only: We always get a valid instance pointer if we just
         created it. In case that the instance is being destroyed or the
         command is unknown, we jump to exit path of nfulnl_recv_config().
         This patch doesn't modify this handling.

      2) Config only: In this case, the instance must always exist since the
         user is asking for configuration updates. If the instance doesn't exist
         this returns -ENODEV.

      3) No command and no configs are specified: This case is rare. The
         user is sending us a config message with neither commands nor
         config options. In this case, we have to check if the instance exists
         and bail out otherwise. Before this patch, it was possible to send a
         config message with no command and no config updates for an
         unexisting instance without triggering an error. So this is the only
         case that changes.

      net/mlx4_core: Replace VF zero mac with random mac in mlx4_core

      By design, when no default MAC addresses are set in the Hypervisor for 
VFs,
      the VFs are passed zero-macs. When such a MAC is received by the VF, it
      generates a random MAC address and registers that MAC address
      with the Hypervisor.

      This random mac generation is currently done in the mlx4_en module.
      There is a problem, though, if the mlx4_ib module is loaded by a VF before
      the mlx4_en module. In this case, for RoCE, mlx4_ib will see the 
un-replaced
      zero-mac and register that zero-mac as part of QP1 initialization.

      Having a zero-mac in the port's MAC table creates problems for a
      Baseboard Management Console. The BMC occasionally sends packets with a
      zero-mac destination MAC. If there is a zero-mac present in the port's
      MAC table, the FW will send such BMC packets to the host driver rather 
than
      to the wire, and BMC will stop working.

      To address this problem, we move the replacement of zero-mac addresses
      with random-mac addresses to procedure mlx4_slave_cap(), which is part of 
the
      driver startup for VFs, and is before activation of mlx4_ib and mlx4_en.
      As a result, zero-mac addresses will never be registered in the port MAC 
table
      by the driver.

      In addition, when mlx4_en does initialize the net device, it needs to set
      the NET_ADDR_RANDOM flag in the netdev structure if the address was
      randomly generated. This is done so that udev on the VM does not create
      a new device name after each VF probe (VM boot and such). To accomplish 
this,
      we add a per-port flag in mlx4_dev which gets set whenever mlx4_core 
replaces
      a zero-mac with a randomly-generated mac. This flag is examined when 
mlx4_en
      initializes the net-device.

      net/mlx5_core: Add pci error handlers to mlx5_core driver

      This patch implement the pci_error_handlers for mlx5_core which allow the
      driver to recover from PCI error.

      Once an error is detected in the PCI, the mlx5_pci_err_detected is called
      and it:
      1) Marks the device to be in 'Internal Error' state.
      2) Dispatches an event to the mlx5_ib to flush all the outstanding cqes
      with error.
      3) Returns all the on going commands with error.
      4) Unloads the driver.

      Afterwards, the FW is reset and mlx5_pci_slot_reset is called and it
      enables the device and restore it's pci state.

      If the later succeeds, mlx5_pci_resume is called, and it loads the SW
      stack.

      tipc: move fragment importance field to new header position

      In commit e3eea1eb47a ("tipc: clean up handling of message priorities")
      we introduced a field in the packet header for keeping track of the
      priority of fragments, since this value is not present in the specified
      protocol header. Since the value so far only is used at the transmitting
      end of the link, we have not yet officially defined it as part of the
      protocol.

      Unfortunately, the field we use for keeping this value, bits 13-15 in
      in word 5, has turned out to be a poor choice; it is already used by the
      broadcast protocol for carrying the 'network id' field of the sending
      node. Since packet fragments also need to be transported across the
      broadcast protocol, the risk of conflict is obvious, and we see this
      happen when we use network identities larger than 2^13-1. This has
      escaped our testing because we have so far only been using small network
      id values.

      We now move this field to bits 0-2 in word 9, a field that is guaranteed
      to be unused by all involved protocols.

      tcp: avoid spurious SYN flood detection at listen() time

      At listen() time, there is a small window where listener is visible with
      a zero backlog, triggering a spurious "Possible SYN flooding on port"

      Nothing prevents us from setting the correct backlog.

      tcp/dccp: fix potential NULL deref in __inet_inherit_port()

      As we no longer hold listener lock in fast path, it is possible that a
      child is created right after listener freed its bound port, if a close()
      is done while incoming packets are processed.

      __inet_inherit_port() must detect this and return an error,
      so that caller can free the child earlier.

      ACPICA: Tables: Fix FADT dependency regression

      Some logics actually relying on the existence of FADT, currently relies on
      the number of loaded tables. This false dependency can easily trigger
      regressions. One of them has been introduced by commit 8ec3f459073e
      (ACPICA: Tables: Fix global table list issues by removing fixed table).

      The commit changing the fixed table indexes results in the change of FADT
      table index, originally, it was 3 (thus the installed table count should 
be
      greater than 4), while currently it is 0 (and the installed table count 
may
      be 3).

      This patch fixes this regression by cleaning up the code. Lv Zheng.

      Partially revert "clk: mvebu: Convert to clk_hw based provider APIs"

      This partially reverts commit eca61c9ff2588e1df373e61078e1874976315839.

      Thomas reports that it causes regressions on Armada XP devices.
      This is because of_clk_get_parent_name() relies on the property
      'clock-output-names' to resolve the name of a clock's parent,
      without trying to get the clock from the framework and call
      __clk_get_name(). Given that Armada XP devices don't have the
      'clock-output-names' property, of_clk_get_parent_name() returns
      the name of the node which doesn't match the actual parent
      clock's name at all, causing CPU clocks to never link up with
      their parents.

      EDAC: Use edac_debugfs_remove_recursive()

      debugfs_remove() is used to remove a file or a directory from the
      debugfs filesystem, but mci->debugfs might not empty.

      This can be triggered by the following sequence:

      1) Enable CONFIG_EDAC_DEBUG
      2) insmod an EDAC module (like i3000_edac or similar)
      3) rmmod this module
      4) we can see files remaining under <debugfs_mountpoint>/edac/ like
         "fake_inject", for example.

      Removing edac_core then, causes a NULL pointer dereference.

      The description in the driver states: "ABX500 does not provide auto ADC,
      so to monitor the required temperatures, a periodic work is used. It is
      more important to not wake up the CPU... If the chip gets too hot during
      a sleep state it's most likely due to external factors, such as the
      surrounding temperature and nothing can be done in S/W."

      So it makes no sense to keep IRQs enabled as it need not be wakeup

      Pull v4.4 EFI updates from Matt Fleming:

        - Make the EFI System Resource Table (ESRT) driver explicitly
          non-modular by ripping out the module_* code since Kconfig doesn't
          allow it to be built as a module anyway. (Paul Gortmaker)

        - Make the x86 efi=debug kernel parameter, which enables EFI debug
          code and output, generic and usable by arm64. (Leif Lindholm)

        - Add support to the x86 EFI boot stub for 64-bit Graphics Output
          Protocol frame buffer addresses. (Matt Fleming)

        - Detect when the UEFI v2.5 EFI_PROPERTIES_TABLE feature is enabled
          in the firmware and set an efi.flags bit so the kernel knows when
          it can apply more strict runtime mapping attributes - Ard Biesheuvel

        - Auto-load the efi-pstore module on EFI systems, just like we
          currently do for the efivars module. (Ben Hutchings)

        - Add "efi_fake_mem" kernel parameter which allows the system's EFI
          memory map to be updated with additional attributes for specific
          memory ranges. This is useful for testing the kernel code that handles
          the EFI_MEMORY_MORE_RELIABLE memmap bit even if your firmware
          doesn't include support. (Taku Izumi)

      Note: there is a semantic conflict between the following two commits:

        8a53554e12e9 ("x86/efi: Fix multiple GOP device support")
        ae2ee627dc87 ("efifb: Add support for 64-bit frame buffer addresses")

      KVM: x86: fix RSM into 64-bit protected mode

      In order to get into 64-bit protected mode, you need to enable
      paging while EFER.LMA=1.  For this to work, CS.L must be 0.
      Currently, we load the segments before CR0 and CR4, which means
      that if RSM returns into 64-bit protected mode CS.L is already 1
      and everything breaks.

      Luckily, CS.L=0 is always the case when executing RSM, because it
      is forbidden to execute RSM from 64-bit protected mode.  Hence it
      is enough to load CR0 and CR4 first, and only then the segments.

      These ware triggered by mod_verify_sig() invocations of pkcs_verify(), and
      are are being caused by an unaligned desc at (sha1, digest_size is 0x14)
              desc = digest + digest_size;

      To fix this, pkcs7_verify needs to make sure that desc is pointing
      at an aligned value past the digest_size, and kzalloc appropriately,
      taking alignment values into consideration.

      As all the import functions and export functions are virtually
      identical, factor out their common parts into a generic
      mv_cesa_ahash_import() and mv_cesa_ahash_export() respectively.  This
      performs the actual import or export, and we pass the data pointers and
      length into these functions.

      We have to switch a % const operation to do_div() in the common import
      function to avoid provoking gcc to use the expensive 64-bit by 64-bit
      modulus operation.

      crypto: marvell/cesa - fix wrong hash results

      Attempting to use the sha1 digest for openssh via openssl reveals that
      the result from the hash is wrong: this happens when we export the
      state from one socket and import it into another via calling accept().

      The reason for this is because the operation is reset to "initial block"
      state, whereas we may be past the first fragment of data to be hashed.

      Arrange for the operation code to avoid the initialisation of the state,
      thereby preserving the imported state.

      crypto: marvell/cesa - initialise struct mv_cesa_ahash_req

      When a AF_ALG fd is accepted a second time (hence hash_accept() is
      used), hash_accept_parent() allocates a new private context using
      sock_kmalloc().  This context is uninitialised.  After use of the new
      fd, we eventually end up with the kernel complaining:

      marvell-cesa f1090000.crypto: dma_pool_free cesa_padding, c0627770/0 (bad 
dma)

      where c0627770 is a random address.  Poisoning the memory allocated by
      the above sock_kmalloc() produces kernel oopses within the marvell hash
      code, particularly the interrupt handling.

      The following simplfied call sequence occurs:

      hash_accept()
        crypto_ahash_export()
          marvell hash export function
        af_alg_accept()
          hash_accept_parent()  <== allocates uninitialised struct hash_ctx
        crypto_ahash_import()
          marvell hash import function

      hash_ctx contains the struct mv_cesa_ahash_req in its req.__ctx member,
      and, as the marvell hash import function only partially initialises
      this structure, we end up with a lot of members which are left with
      whatever data was in memory prior to sock_kmalloc().

      Add zero-initialisation of this structure.

      crypto: marvell/cesa - fix stack smashing in marvell/hash.c

      Several of the algorithms in marvell/hash.c have a statesize of zero.
      When an AF_ALG accept() on an already-accepted file descriptor to
      calls into hash_accept(), this causes:

        char state[crypto_ahash_statesize(crypto_ahash_reqtfm(req))];

      to be zero-sized, but we still pass this to:

        err = crypto_ahash_export(req, state);

      which proceeds to write to 'state' as if it was a "struct md5_state",
      "struct sha1_state" etc.  Add the necessary initialisers for the
      .statesize member.

      x86/efi: Fix multiple GOP device support

      When multiple GOP devices exists, but none of them implements
      ConOut, the code should just choose the first GOP (according to
      the comments). But currently 'fb_base' will refer to the last GOP,
      while other parameters to the first GOP, which will likely
      result in a garbled display.

      I can reliably reproduce this bug using my ASRock Z87M Extreme4
      motherboard with CSM and integrated GPU disabled, and two PCIe
      video cards (NVidia GT640 and GTX980), booting from efi-stub
      (booting from grub works fine).  On the primary display the
      ASRock logo remains and on the secondary screen it is garbled
      up completely.

      tipc: eliminate risk of stalled link synchronization

      In commit 6e498158a827 ("tipc: move link synch and failover to link 
aggregation level")
      we introduced a new mechanism for performing link failover and
      synchronization. We have now detected a bug in this mechanism.

      During link synchronization we use the arrival of any packet on
      the tunnel link to trig a check for whether it has reached the
      synchronization point or not. This has turned out to be too
      permissive, since it may cause an arriving non-last SYNCH packet to
      end the synch state, just to see the next SYNCH packet initiate a
      new synch state with a new, higher synch point. This is not fatal,
      but should be avoided, because it may significantly extend the
      synchronization period, while at the same time we are not allowed
      to send NACKs if packets are lost. In the worst case, a low-traffic
      user may see its traffic stall until a LINK_PROTOCOL state message
      trigs the link to leave synchronization state.

      At the same time, LINK_PROTOCOL packets which happen to have a (non-
      valid) sequence number lower than the tunnel link's rcv_nxt value will
      be consistently dropped, and will never be able to resolve the situation
      described above.

      We fix this by exempting LINK_PROTOCOL packets from the sequence number
      check, as they should be. We also reduce (but don't completely
      eliminate) the risk of entering multiple synchronization states by only
      allowing the (logically) first SYNCH packet to initiate a synchronization
      state. This works independently of actual packet arrival order.

      Fixes: commit 6e498158a827 ("tipc: move link synch and failover to link 
aggregation level")

      Revert the commit e2ca690b657f ("ipv4/icmp: redirect messages
      can use the ingress daddr as source"), which tried to introduce a more
      suitable behaviour for ICMP redirect messages generated by VRRP routers.
      However RFC 5798 section 8.1.1 states:

          The IPv4 source address of an ICMP redirect should be the address
          that the end-host used when making its next-hop routing decision.

      while said commit used the generating packet destination
      address, which do not match the above and in most cases leads to
      no redirect packets to be generated.

      Intel Wired LAN Driver Updates 2015-10-13

      This series contains updates to i40e, i40evf, ixgbe and fm10k.

      Carolyn cleans up ndo_bridge_getlink() by flagging a parameter as
      __always_unused, since it is never used.  Adds a member to the nvm_info
      struct to store OEM version info to be output either by OID or ethtool.

      Neerav cleans up a remaining bit shift to use BIT() macro.

      Mitch fixes the i40evf driver to properly handle calls to its
      ndo_set_mac_address() method.  It did not properly check to see if the
      override would be allowed by the PF driver, and it never removed the old
      address from its filter list.  Cleaned up the use of
      i40e_enable_vf_mappings() in i40e_alloc_vfs(), since it is just redundant
      since we already call it by i40e_reset_vf().  Fixed a possible panic
      in some circumstances where the firmware may fail to allocate a VSI for
      a VF by checking the return value from i40e_alloc_vf_res() and don't
      try to configure the device further if it failed.

      Greg fixes the parsing of CEE App TLVs so the caller does not have to
      consider whether the App came from a CEE or IEEE DCBx negotiation.

      Shannon moves the device ids into a standalone file due to the desire
      to write user-land drivers (and other requests) without needing the rest
      of the include files.

      Catherine adds the ability to save the module information from
      get_phy_capabilities() to be used to determine which speeds the module
      supports.  Also cleaned up the PHY structure by removing unused members
      and add the ability to store the PHY capabilities reported by the
      firmware.

      Emil modifies ixgbe to ensure that flow control packets initiated by the
      VF are dropped and reported as spoofed.

      Jacob cleans up the fm10k driver to avoid buffer overflow by using
      sprintf(), so convert to using snprintf().  Also fixed the use of an
      enum as a boolean, so check for the actual value of NETREG_UNINITIALIZED
      in case it ever changes from the current value of zero.

      v2: Dropped patch 11 of the original series, which added functions that
          were never used.

      s390/spinlock: remove unneeded serializations at unlock

      the kernel locks have aqcuire/release semantics. No operation done
      after the lock can be "moved" before the lock and no operation before
      the unlock can be moved after the unlock. But it is perfectly fine
      that memory accesses which happen code wise after unlock are performed
      within the critical section.
      On s390x, reads are in-order with other reads (PoP section
      "Storage-Operand Fetch References") and writes are in-order with
      other writes (PoP section "Storage-Operand Store References"). Writes
      are also in-order with reads to the same memory location (PoP section
      "Storage-Operand Store References"). To other CPUs (and the channel
      subsystem), reads additionally appear to be performed prior to reads or
      writes that happen after them in the conceptual sequence (PoP section
      "Relation between Operand Accesses").
      So at least as observed by other CPUs and the channel subsystem, reads
      inside the critical sections will not happen after unlock (and writes
      are in-order anyway). That's exactly what we need for "RELEASE
      operations" (memory-barriers.txt): "It guarantees that all memory
      operations before the RELEASE operation will appear to happen before the
      RELEASE operation with respect to the other components of the system."

      s390/zcrypt: use explicit return code for flushed requests

      If a AP device is removed while messages are still pending, the requests

pointer
      for the reply. The message type receive handler recognize this and create
      a fake hardware error TYPE82_RSP_CODE / REP82_ERROR_MACHINE_FAILURE.
      The message with the hardware error then causes a printk and a return
      code of -EAGAIN.

      Replace the intricate scheme with an explicit return code for this 
sitation
      and avoid the error message.

      s390/zcrypt: remove duplicate low level functions

      the same PQAP(TAPQ) command. Consolidate the three into a single
      ap_test_queue function that returns the AP status and the 64-bit
      result. The exception table entry for PQAP(TAPQ) can be avoided
      if the T bit for the APFT facility is set only if test_facility(15)
      indicated that the facility is present.

      s390/etr,stp: fix possible deadlock on machine check

      The first level machine check handler for etr and stp machine checks may
      call queue_work() while in nmi context. This may deadlock e.g. if the
      machine check happened when the interrupted context did hold a lock, that
      also will be acquired by queue_work().
      Therefore split etr and stp machine check handling into first and second
      level handling. The second level handling will then issue the queue_work()
      call in process context which avoids the potential deadlock.

      s390/udelay: make udelay have busy loop semantics

      When using systemtap it was observed that our udelay implementation is
      rather suboptimal if being called from a kprobe handler installed by
      systemtap.

      The problem observed when a kprobe was installed on lock_acquired().
      When the probe was hit the kprobe handler did call udelay, which set
      up an (internal) timer and reenabled interrupts (only the clock comparator
      interrupt) and waited for the interrupt.
      This is an optimization to avoid that the cpu is busy looping while 
waiting
      that enough time passes. The problem is that the interrupt handler still
      does call irq_enter()/irq_exit() which then again can lead to a deadlock,
      since some accounting functions may take locks as well.

      If one of these locks is the same, which caused lock_acquired() to be
      called, we have a nice deadlock.

      This patch reworks the udelay code for the interrupts disabled case to
      immediately leave the low level interrupt handler when the clock
      comparator interrupt happens. That way no C code is being called and the
      deadlock cannot happen anymore.

      The program parameter can be used to mark hardware samples with
      some token.  Previously, it was used to mark guest samples only.

      Improve the program parameter doubleword by combining two parts,
      the leftmost LPP part and the rightmost PID part.  Set the PID
      part for processes by using the task PID.
      To distinguish host and guest samples for the kernel (PID part
      is zero), the guest must always set the program paramater to a
      non-zero value.  Use the leftmost bit in the LPP part of the
      program parameter to be able to detect guest kernel samples.

      The sclp console and tty code currently uses several message text

      s390/entry: add assembler macro to conveniently tests under mask

      Various functions in entry.S perform test-under-mask instructions
      to test for particular bits in memory.  Because test-under-mask uses
      a mask value of one byte, the mask value and the offset into the
      memory must be calculated manually.  This easily introduces errors
      and is hard to review and read.

      Introduce the TSTMSK assembler macro to specify a mask constant and
      let the macro calculate the offset and the byte mask to generate a
      test-under-mask instruction.  The benefit is that existing symbolic
      constants can now be used for tests.  Also the macro checks for
      zero mask values and mask values that consist of multiple bytes.

      s390/fpu: always enable the vector facility if it is available

      If the kernel detects that the s390 hardware supports the vector
      facility, it is enabled by default at an early stage.  To force

      With enabling the vector facility by default, the FPU save and

      to manage expensive control register updates to enable or disable
      the vector enablement control for particular processes.

      During allocation of extended measurement blocks we check if the device is
      already active for channel measurement and add the device to a list of
      devices with active channel measurement. The check is done under ccwlock
      protection and the list modification is guarded by a different lock.

      To guarantee that both states are in sync make sure that both locks
      are held during the allocation process (like it's already done for the
      "normal" measurement block allocation).

      s390/cio: fix use after free in cmb processing

      Devices with active channel measurement are included in a list. When a
      device is removed without deactivating channel measurement first the
      list_head is freed but still used. Fix this by making sure that
      channel measurement is deactivated during device deregistration.

      For devices that we deregister because they are no longer accessible
      deactivating channel measurement will fail. In this case we can report
      success because the FW will no longer access the measurement block.

      In addition to these steps keep an extra device reference while
      channel measurement is active.

      s390/barrier: avoid serialization in [smp_]rmb and [smp_]wmb

      The principles of operation says:

      The storage-operand fetch references of one instruction
      occur after those of all preceding instructions and
      before those of subsequent instructions, as observed
      by other CPUs and by channel programs.
      [...]
      The CPU may fetch the operands of instructions before the
      instructions are executed.
      [...]
      The CPU may delay placing results in storage.
      [...]
      the results of one instruction are placed in storage after
      the results of all preceding instructions have been placed
      in storage and before any results of the succeeding
      instructions are stored, as observed by other CPUs and by
      the channel subsystem.

      which boils down to:
      - reads are in order
      - writes are in order
      - reads can happen earlier
      - writes can happen later

      By definition (see memory-barrier.txt) read barriers orders
      reads vs reads and write barriers orders writes agains writes.
      but neither of these orders reads vs. writes.

      That means we can implement smp_wmb,smp_rmb,wmb and rmb as
      simple compiler barriers. To avoid reviewing all driver code
      for correct barrier usage we keep dma_[rw]mb as serialization
      for now.

      s390/vdso: use correct memory barrier

      By definition smp_wmb only orders writes against writes. (Finish all
      previous writes, and do not start any future write). To protect the
      vdso init code against early reads on other CPUs, let's use a full
      smp_mb at the end of vdso init. As right now smp_wmb is implemented
      as full serialization, this needs no stable backport, but this change
      will be necessary if we reimplement smp_wmb.

      s390/dasd: mark DASD devices as non rotational

      We were able to reduce the CPU overhead of big paging scenarios
      when announcing our paging disks as non-rotational.
      Almost all dasd devices are implemented in storage servers with
      cache, raid, striping and lots of magic. There is no point in
      optimizing the disk schedulers and swap code for a single platter
      moving arm rotational disks. Given the complexity of the setup
      and the fact that this change is mostly to disable the additional
      overhead in swap code, lets keep the other functionality unchanged
      and do not disable the this device as entropy source - unlike other
      non-rotational devices.

      the commit, one in -next headed for v4.4 and this one for v4.3. Turns
      out we'll need to backport more fixes from -next, and they conflict with
      the v4.3 version. It gets messy. It will be easiest to revert this one,
      and backport all the relevant commits from -next without modifications;
      they apply cleanly after this revert.

      rtlwifi: rtl818x: Move drivers into new realtek directory

      Now that a new mac80211-based driver for Realtek devices has been 
submitted,
      it is time to reorganize the directories. Rather than having directories
      rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
      drivers/net/wireless/realtek/. This change simplifies the directory
      structure, but does not result in any configuration changes that are
      visable to the user.

      irqchip/mxs: Add Alphascale ASM9260 support

      Freescale iMX23/iMX28 and Alphascale ASM9260 have similar interrupt
      collectors. We already prepared the mxs driver to handle a different
      register layout. Add the actual ASM9260 support.

      Differences between these devices:
      - Different register offsets
      - Different count of interupt lines per register
      - ASM9260 does not provide reset bit
      - ASM9260 does not support FIQ.

      irqchip/mxs: Prepare driver for hardware with different offsets

      Alphascale asm9260 has similar functionality but different register
      offsets. To support asm9260 in the mxs driver we need to rework the
      hardcoded access mechanisms.

      - Define SET_REG and CLR_REG. These controllers support seperate CLR and
        SET offsets for each register.

      - Reimplement HW_ICOLL_INTERRUPT with SET_REG and CLR_REG to make it
        usable for both cases.

      - Instead of using icoll_base and adding the offsets at runtime,
        create a new data structure which contains base pointers to all
        required regitsters and use it.

      - Split out functionality, which is required for the init code of mxs
        and asm9260, into helper functions

      ixgbe: add flow control ethertype to the anti-spoofing filter

      This patch makes sure that flow control packets initiated by the VF are
      dropped and reported as spoofed.

      Flow control packets can be used to limit the throughput or as DOS
      attack when generated from a VF. Flow control is not supported per VF
      hence any pause frames generated from a VF are considered malicious.

      Also cleaned up indentation and some redundant comments.

      i40e/i40evf: Refactor PHY structure and add phy_capabilities enum

      Remove unused members in the PHY structure and add a new member to store
      all the capabilities the PHY has as reported by the FW. This information
      will help us determine what speeds the device is capable of when link is
      down.

      Also add an enum to decode the PHY types the NVM is capable of.
      Use the phy_types variable to determine what phy types are possible
      when link is down instead of device id as it will be more accurate.

      When on a backplane device, we do not support changing any settings,
      however we should display all the phy_types we are capable of so if we
      see a backplane dev ID set supported and advertised purely based on
      the phy_types variable.

      i40e/i40evf: Add module_types and update_link_info

      Add a module_types variable to the link_info struct to save the module
      information from get_phy_capabilities. This information can be used to
      determine which speeds the module supports.

      Also add a new function update_link_info which updates the module_types
      parameter and then calls get_link_info. This function should be called
      in place of get_link_info so that the module_types variable stays
      up-to-date with the rest of the link information.

      The EAS table does not reflect the values that are actually returned,
      so instead, basing these values on the Ethernet compliance codes
      specified in table 33 of SFF-8436 as these have been accurate.

      Use the new variable in ethtool to differentiate between a 10G/1G dual
      speed fiber module and a 10G only module.

      i40e: don't panic on VSI allocation failure

      In some circumstances, the firmware may fail to allocate a VSI for a VF.
      When this happens, the driver does not react well to the bad news and
      has a panic attack.

      To fix this problem, check the return value from i40e_alloc_vf_res and
      don't try to configure the device further if it failed. Additionally,
      explicitly clear the INIT bit when we free VF resources, so that this
      bit will be in the proper state in the failure case, and won't blow up
      elsewhere.

      board id combinations. We get these IDs from the target using BMI after 
otp.bin
      has been started.

      This patch reorders the call to the function ath10k_core_fetch_board_file
      so that we have OTP binary before requesting for boardid-chipid. We get 
this
      OTP data after parsing firmware-N.bin.

      ath10k: add board 2 API support

      QCA6174 needs different board files based on board type. To make it 
easier to
      distribute multiple board files and automatically choose correct board 
file
      create a simple TLV file format following the same principles as with FW 
IEs.
      The file is named board-2.bin and contain multiple board files. Each 
board file
      then can have multiple names.

      ath10k searches for file board-N.bin (where N is the interface version 
number
      for the board file, just like we for firmware files) in /lib/firmware/*, 
for
      example for qca99x0 it will try to find it here:

      /lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin

      If ath10k doesn't find board-2.bin then it will fallback to the old 
board.bin file.

      This patch adds a simple name scheme using pci device id which for now 
will be
      used by qca6174:

      bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x

      This removes the old method of having subsystem ids in ar->spec_board_id 
and
      using that in the board file name.

      btrfs: fix use after free iterating extrefs

      The code for btrfs inode-resolve has never worked properly for
      files with enough hard links to trigger extrefs.  It was trying to
      get the leaf out of a path after freeing the path:

        btrfs_release_path(path);
        leaf = path->nodes[0];
        item_size = btrfs_item_size_nr(leaf, slot);

      The fix here is to use the extent buffer we cloned just a little higher
      up to avoid deadlocks caused by using the leaf in the path.

      We don't verify that all the balance filter arguments supplemented by

      At the moment this means only the 'limit' filter, but we're going to add
      a few more soon so it's better to have that fixed. Also in older stable

      tcp/dccp: fix behavior of stale SYN_RECV request sockets

      When a TCP/DCCP listener is closed, its pending SYN_RECV request sockets
      become stale, meaning 3WHS can not complete.

      But current behavior is wrong :
      incoming packets finding such stale sockets are dropped.

      We need instead to cleanup the request socket and perform another
      lookup :
      - Incoming ACK will give a RST answer,
      - SYN rtx might find another listener if available.
      - We expedite cleanup of request sockets and old listener socket.

      PM / Domains: Fix validation of latency constraints in genpd governor

      Commit ba2bbfbf6307 (PM / Domains: Remove intermediate states from the
      power off sequence) changed the power off sequence in genpd. That also
      required some updates regarding the validation of latency constraints in
      the genpd governor. Unfortunate that wasn't covered, so let's fix this.

      From a runtime PM and latency point of view, we need to consider the worst
      case scenario while validating latency constraints. That's typically when
      a call to pm_runtime_get_sync() needs to wait for a ongoing runtime
      suspend operation to be carried out, as it then also needs to wait for the
      device to be runtime resumed again.

      The above mentioned commit made the genpd governor's ->stop_ok() callback
      responsible of validating genpd's device's runtime suspend/resume latency.
      In other words, the constraint needs to be validated towards the relevant
      latencies present in genpd's ->runtime_suspend|resume() callbacks.

      Earlier, that included latencies from the ->stop|start() callbacks, but as
      ->save|restore_state() are now also being invoked from genpd's
      ->runtime_suspend|resume() and to comply with the worst case scenario,
      let's take also those latencies into account.

      iommu/vt-d: fix range computation when making room for large pages

      In preparation for the installation of a large page, any small page
      tables that may still exist in the target IOV address range are
      removed.  However, if a scatter/gather list entry is large enough to
      fit more than one large page, the address space for any subsequent
      large pages is not cleared of conflicting small page tables.

      This can cause legitimate mapping requests to fail with errors of the
      form below, potentially followed by a series of IOMMU faults:

      ERROR: DMA PTE for vPFN 0xfde00 already set (to 7f83a4003 not 7e9e00083)

      In this example, a 4MiB scatter/gather list entry resulted in the
      successful installation of a large page @ vPFN 0xfdc00, followed by
      a failed attempt to install another large page @ vPFN 0xfde00, due to
      the presence of a pointer to a small page table @ 0x7f83a4000.

      To address this problem, compute the number of large pages that fit
      into a given scatter/gather list entry, and use it to derive the
      last vPFN covered by the large page(s).

      irqchip/gic: Kill the xlate method

      We are now left with only two use models for the GIC driver:
      - Via a firmware interface, which mandates a hierarchical domain,
        and the use of the 'translate' method
      - The legacy platforms, which assume irq==hwirq, hence not using
        the 'xlate' method.

      The logical conclusion is that we can now nuke the 'xlate' method
      altogether.

      irqchip/gic: Get rid of gic_init_bases()

      Since nobody is using gic_init_bases anymore outside of the GIC
      driver itself, let's do a bit of housekeeping and remove the now
      useless entry point.

      Only gic_init() is now exposed to the rest of the kernel for the
      benefit of legacy systems.

      where:
      - model is the value assigned to acpi_irq_model
      - fwnode is the identifier for the irqdomain mapping
        GSI interrupts

      As nobody calls this code yet, the current code is (mostly)

      acpi/gsi: Always perform an irq domain lookup

      Instead of directly passing NULL to the various irq_domain functions,
      start by looking up the domain with a domain identifier..

      As this identifier is permanently set to NULL, the lookup function will
      return the same value (no domain found) and the default will be used,
      preserving the current behaviour.

      irqdomain: Add a fwnode_handle allocator

      In order to be able to reference an irqdomain from ACPI, we need
      to be able to create an identifier, which is usually a struct
      device_node.

      This device node does't really fit the ACPI infrastructure, so
      we cunningly allocate a new structure containing a fwnode_handle,
      and return that.

      This structure doesn't really point to a device (interrupt
      controllers are not "real" devices in Linux), but as we cannot
      really deny that they exist, we create them with a new fwnode_type
      (FWNODE_IRQCHIP).

      irqdomain: Introduce a firmware-specific IRQ specifier structure

      So far the closest thing to a generic IRQ specifier structure is
      of_phandle_args, which happens to be pretty OF specific (the of_node
      pointer in there is quite annoying).

      Let's introduce 'struct irq_fwspec' that can be used in place of
      of_phandle_args for OF, but also for other firmware implementations
      (that'd be ACPI). This is used together with a new 'translate' method
      that is the pendent of 'xlate'.

      We convert irq_create_of_mapping to use this new structure (with a
      small hack that will be removed later).

      in userspace since commit b74a07beed0e, "KVM: Remove kernel-allocated
      memory regions", 2010-06-21); that is a nice bonus.

      The next patch will make x86_set_memory_region fill the

      anymore, it makes sense to build it in x86_set_memory_region
      directly; it also simplifies the callers.

      can: avoid using timeval for uapi

      The can subsystem communicates with user space using a bcm_msg_head
      header, which contains two timestamps. This is problematic for
      multiple reasons:

      a) The structure layout is currently incompatible between 64-bit
         user space and 32-bit user space, and cannot work in compat
         mode (other than x32).

      b) The timeval structure layout will change in 32-bit user
         space when we fix the y2038 overflow problem by redefining
         time_t to 64-bit, making new 32-bit user space incompatible
         with the current kernel interface.
         Cars last a long time and often use old kernels, so the actual
         users of this code are the most likely ones to migrate to y2038
         safe user space.

      This tries to work around part of the problem by changing the
      publicly visible user interface in the header, but not the binary
      interface. Fortunately, the values passed around in the structure
      are relative times and do not actually suffer from the y2038
      overflow, so 32-bit is enough here.

      We replace the use of 'struct timeval' with a newly defined
      'struct bcm_timeval' that uses the exact same binary layout
      as before and that still suffers from problem a) but not problem
      b).

      The downside of this approach is that any user space program
      that currently assigns a timeval structure to these members
      rather than writing the tv_sec/tv_usec portions individually
      will suffer a compile-time error when built with an updated
      kernel header. Fixing this error makes it work fine with old
      and new headers though.

      We could address problem a) by using '__u32' or 'int' members
      rather than 'long', but that would have a more significant
      downside in also breaking support for all existing 64-bit user
      binaries that might be using this interface, which is likely
      not acceptable.

it's

      drm/i915: Deny wrapping an userptr into a framebuffer

      Pinning a userptr onto the hardware raises interesting questions about
      the lifetime of such a surface as the framebuffer extends that life
      beyond the client's address space. That is the hardware will need to
      keep scanning out from the backing storage even after the client wants
      to remap its address space. As the hardware pins the backing storage,
      the userptr becomes invalid and this raises a WARN when the clients
      tries to unmap its address space. The situation can be even more
      complicated when the buffer is passed between processes, between a
      client and display server, where the lifetime and hardware access is
      even more confusing. Deny it.

      drm/i915: Enable DPLL VGA mode before P1/P2 divider write

      Apparently writing the DPLL register P1/P2 divider fields won't trigger
      an actual change in the DPLL output unless VGA mode is enabled for
      prior to the register write that changes the P1/P2 dividers. The write
      with the new P1/P2 divider can itself disable VGA mode again without
      problems.

      I tested the behaviour on my 946GZ, and when manually frobbing the
      register with the display on, the behaviour is very clear. However I
      can't explain why this machine actually works. The P1/P2 divider
      changes caused by normal modesets do seem to make it through to the
      hardware somehow since I get a stable picture on the monitor with
      any resolution. Maybe it's the "three times for luck" stuff that
      somehow masks the problem, or something.

      But apparently there are machines (eg. Nick Bowler's G45) where that
      isn't the case and we fail to get the correct clock from the DPLL.

      Things used to work because we enabled VGA mode for disabled DPLLs,
      so when re-enabling the DPLL VGA mode was enabled just prior to the
      first register write, and hence the P1/P2 change went through without
      a hitch. That got changed in

      b8afb9113c51 drm/i915: Keep GMCH DPLL VGA mode always disabled

      in the name of consistency. In order to keep the consistency part,
      leave VGA mode disabled for disabled DPLLs, but turn it on just prior
      to updating the P1/P2 dividers to make sure the hardware picks up
      on the new values.

      netfilter: sync with packet rx also after removing queue entries

      We need to sync packet rx again after flushing the queue entries.
      Otherwise, the following race could happen:

      cpu1: nf_unregister_hook(H) called, H unliked from lists, calls
      synchronize_net() to wait for packet rx completion.

      Problem is that while no new nf_queue_entry structs that use H can be
      allocated, another CPU might receive a verdict from userspace just before
      cpu1 calls nf_queue_nf_hook_drop to remove this entry:

      cpu2: receive verdict from userspace, lock queue
      cpu2: unlink nf_queue_entry struct E, which references H, from queue list
      cpu1: calls nf_queue_nf_hook_drop, blocks on queue spinlock
      cpu2: unlock queue
      cpu1: nf_queue_nf_hook_drop drops affected queue entries
      cpu2: call nf_reinject for E
      cpu1: kfree(H)
      cpu2: potential use-after-free for H

      bridge: vlan: cleanups & fixes (part 3)

      Patch 01 converts the vlgrp member to use rcu as it was already used in a
      similar way so better to make it official and use all the available RCU
      instrumentation. Patch 02 fixes a bug where the vlan_list can be traversed
      without rtnl or rcu held which could lead to using freed entries.
      Patch 03 removes some redundant code that isn't needed anymore.
      Patch 04 fixes a bug reported by Ido Schimmel about the vlan_flush order
      and switchdevs, it moves it back.

      v2: patch 03 and 04 are new, couldn't escape the second synchronize_rcu()
      since the rhtable destruction can sleep

      bridge: vlan: move back vlan_flush

      Ido Schimmel reported a problem with switchdev devices because of the
      order change of del_nbp operations, more specifically the move of
      nbp_vlan_flush() which deletes all vlans and frees vlgrp after the
      rx_handler has been unregistered. So in order to fix this move
      vlan_flush back where it was and make it destroy the rhtable after
      NULLing vlgrp and waiting a grace period to make sure noone can see it.

      As Ido Schimmel pointed out the vlan_vid_del() code in nbp_vlan_flush is
      unnecessary (and is actually a remnant of the old vlan code) so we can
      remove it.

      br_fill_ifinfo is called by br_ifinfo_notify which can be called from
      many contexts with different locks held, sometimes it relies upon
      bridge's spinlock only which is a problem for the vlan code, so use
      explicitly rcu for that to avoid problems.

      bridge: vlan: use proper rcu for the vlgrp member

      The bridge and port's vlgrp member is already used in RCU way, currently
      we rely on the fact that it cannot disappear while the port exists but
      that is error-prone and we might miss places with improper locking
      (either RCU or RTNL must be held to walk the vlan_list). So make it
      official and use RCU for vlgrp to catch offenders. Introduce proper vlgrp
      accessors and use them consistently throughout the code.

      net: VRF support in IPv6 stack

      Initial support for VRF in IPv6 stack. Makes IPv6 functionality on par
      with IPv4 -- ping, tcp client/server and udp client/server all work fine.
      tcpdump on vrf device and external tap (e.g., host side tap device) shows
      all packets with proper addresses. IPv6 does not need the source address
      operation like IPv4. Verified vti6 works properly in my setup as does use
      of an IPv6 address on the VRF device.

      v3
      - re-based to top of net-next (updates per net namespace changes by Eric)
      - fixed dst_entry typecasts as requested by Dave
      - added flags to inet6_rtm_getroute (IPv6 version of deaa0a6a930e)

      v2
      - fixed CONFIG_IPV6 dependency as questioned by Cong
        - if IPV6 is a module, kbuild ensures VRF is a module
        - if IPV6 is disabled IPV6 functionality is compiled out of VRF module
      - addressed comments from Nik over IRC
        - removed duplicate call to netif_is_l3_master in l3mdev_rt6_dst_by_oif
        - changed allocation flag from GFP_ATOMIC to GFP_KERNEL since it is 
init time
        - added free of rt6i_pcpu
        - check_ipv6_frame returns false only if packet is NDISC type

      ipv6: Don't call with rt6_uncached_list_flush_dev

      As originally written rt6_uncached_list_flush_dev makes no sense when
      called with dev == NULL as it attempts to flush all uncached routes
      regardless of network namespace when dev == NULL.  Which is simply
      incorrect behavior.

      Furthermore at the point rt6_ifdown is called with dev == NULL no more
      network devices exist in the network namespace so even if the code in
      rt6_uncached_list_flush_dev were to attempt something sensible it
      would be meaningless.

      Therefore remove support in rt6_uncached_list_flush_dev for handling
      network devices where dev == NULL, and only call 
rt6_uncached_list_flush_dev
       when rt6_ifdown is called with a network device.

      bridge: fix gc_timer mod/del race condition

      commit c62987bbd8a1 ("bridge: push bridge setting ageing_time down to
      switchdev") introduced a timer race condition because the gc_timer can
      get rearmed after it's supposedly stopped and flushed in br_dev_delete()
      leading to a use of freed memory. So take rtnl to sync with bridge
      destruction when setting ageing_timer.
      Here's the trace reproduced with these two commands running in parallel:
      while :; do echo 10000 > /sys/class/net/br0/bridge/ageing_timer; done;
      while :; do brctl addbr br0; ip l set br0 up; ip l set br0 down;
      brctl delbr br0; done;

      ====================
      be2net: patch set

      Patch 1 fixes a FW image compatibility check in the driver that
      prevents certain FW images from being flashed on BE3 (not BE3-R)
      adapters.

      Patch 2 fixes a spin_lock not being released in a failure case in
      be_cmd_notify_wait().

      Patch 3 includes a workaround to pad packets that are only 32b long or 
less
      to be applicabe to BE3 too. This workaround was currently applied only to
      Skyhawk and Lancer chips. Such packets are causing BE3's TX path to stall
      on a SR-IOV config.

      Patch 4 fixes the be_cmd_get_profile_config() routine to set the pf_num
      field in the cmd request. The FW requires this field to be set for it to
      return the specific function's descriptors. If not set, the FW returns
      the descriptors of all the functions on the device. If the first 
descriptor
      is not what is being queried for, the driver will read wrong data.
      This patch fixes this issue by using the GET_CNTL_ATTRIB cmd to query the
      real pci_func_num of a function and then uses it in the GET_PROFILE_CONFIG
      cmd.

      Patch 5 completes an earlier fix that removed the vlan promisc capability
      for VFs. The earlier fix did not update the removal of this capability 
from
      the profile descriptor of the VF. This causes the VF driver to request 
this
      capability when it tries to create it's interface at probe time. This 
could
      potentailly cause the VF probe to fail if the FW enforces strict checking 
of
      the flags based on what was provisoned by the PF.  This strict checking is
      not being done by FW currently but will be fixed in a future version. This
      patch fixes this issue by updating the VF's profile descriptor so that 
they
      match the interface capability flags provisioned by the PF.

      Pls consider adding these patches to the net tree. Thanks!

      be2net: remove vlan promisc capability from VF's profile descriptors

      The commit 435452aa8847 ("Prevent VFs from enabling VLAN promiscuous 
mode")
      fixed the PF driver to not include the VLAN promisc capability while
      provisioning the interface for a VF. But the fix did not remove this

      be2net: fix BE3-R FW download compatibility check

      In the BE3 FW image, unlike Skyhawk's, the "asic_type_rev" field doesn't
      track the asic_rev of chip it is compatible with. When asic_type_rev
      is 0 the image is compatible only with pre-BE3-R chips (asic_rev < 0x10).
      Fix the current compatibility check to take care of this.
      We hit this issue when we try to flash old BE3 images (used prior to the
      release of BE3-R) on pre-BE3-R adapters.

      net/fsl_pq_mdio: fix computed address for the TBI register

      commit afae5ad78b342f401c28b0bb1adb3cd494cb125a
        "net/fsl_pq_mdio: streamline probing of MDIO nodes"

      added support for different types of MDIO devices:
      1) Gianfar MDIO nodes that only map the MII registers
      2) Gianfar MDIO nodes that map the full MDIO register set
      3) eTSEC2 MDIO nodes (which map the full MDIO register set)
      4) QE MDIO nodes (which map only the MII registers)

      However, the implementation for types 1 and 4 would mistakenly assume
      a mapping of the full MDIO register set, thereby computing the address
      for the TBI register starting from the containing structure.
      The TBI register would therefore be accessed at a wrong (much bigger)
      address, not giving the expected result at all.
      This patch restores the correct behavior we had prior to the above one.

      The consequences of this bug are apparent when trying to access a PHY
      with the same address as the value contained in the initial value of
      the TBI register (normally 0); in that case you'll get answers from the
      internal TBI device (even though MDIO/MDC pins are actually *also*
      toggling on the physical bus!).
      Beware that you also need to add a fake tbi node to your device tree
      with an unused address.

      Notice how this fix is related to commit
      220669495bf8b68130a8218607147c7b74c28d2b
        "powerpc: Add TBI PHY node to first MDIO bus"

      which fixed the behavior in kernel 3.3, which was later broken by the
      above commit on kernel 3.7.

      a) make sure the address is computed correctly
      b) make users aware that we're actually accessing that register

      ====================
      net: dsa: mv88e6xxx: fix hardware bridging

      DSA and its drivers currently hook the NETDEV_CHANGEUPPER net_device 
event in
      order to configure the VLAN map of every port.

      This VLAN map is a feature of these switch chips to hardcode and restrict 
which
      output ports a given input port can egress frames to.

      A Linux bridge is a simple untagged VLAN propagated by the bridge code 
itself.
      With a proper 802.1Q support, a driver does not need this hook anymore, 
and
      will simply program the related VLAN object.

      This patchset improves the hardware bridging code in the mv88e6xxx driver 
with
      a strict 802.1Q mode.

      Ideally, the equivalent must be done for Broadcom Starfighter 2 and 
Rocker,
      before completely getting rid of this hook.

      net: dsa: mv88e6xxx: fix hardware bridging

      Playing with the VLAN map of every port to implement "hardware bridging"
      in the 88E6352 driver was a hack until full 802.1Q was supported.

      Indeed with 802.1Q port mode "Disabled" or "Fallback", this feature is
      used to restrict which output ports an input port can egress frames to.

      A Linux bridge is an untagged VLAN. With full 802.1Q support, we don't
      need this hack anymore and can use the "Secure" strict 802.1Q port mode.

      With this mode, the port-based VLAN map still needs to be configured,
      but all the logic is VTU-centric. This means that the switch only cares
      about rules described in its hardware VLAN table, which is exactly what
      Linux bridge expects and what we want.

      Note also that the hardware bridging was broken with the previous
      flexible "Fallback" 802.1Q port mode. Here's an example:

      Port0 and Port1 belong to the same bridge. If Port0 sends crafted tagged
      frames with VID 200 to Port1, Port1 receives it. Even if Port1 is in
      hardware VLAN 200, but not Port0, Port1 will still receive it, because
      Fallback mode doesn't care about invalid VID or non-member source port.

      net: dsa: mv88e6xxx: bridges do not need an FID

      With 88E6352 and similar switch chips, each port has a map to restrict
      which output port this input port can egress frames to.

      The current driver code implements hardware bridging using this feature,
      and assigns to a bridge group the FID of its first member.

      Now that 802.1Q is fully implemented in this driver, a Linux bridge
      which is a simple untagged VLAN, already gets its own FID.

      This patch gets rid of the per-bridge FID and explicits the usage of the
      port based VLAN map feature.

      RDS-TCP: Reset tcp callbacks if re-using an outgoing socket in 
rds_tcp_accept_one()

      Consider the following "duelling syn" sequence between two peers A and B:
                A               B
                SYN1     -->
                        <--     SYN2
                SYN2ACK  -->

      Note that the SYN/ACK has already been sent out by TCP before
      rds_tcp_accept_one() gets invoked as part of callbacks.

      If the inet_addr(A) is numerically less than inet_addr(B),
      the arbitration scheme in rds_tcp_accept_one() will prefer the
      TCP connection triggered by SYN1, and will send a CLOSE for the
      SYN2 (just after the SYN2ACK was sent).

      Since B also follows the same arbitration scheme, it will send the SYN-ACK
      for SYN1 that will set up a healthy ESTABLISHED connection on both sides.
      B will also get a  CLOSE for SYN2, which should result in the cleanup
      of the TCP state machine for SYN2, but it should not trigger any
      stale RDS-TCP callbacks (such as ->writespace, ->state_change etc),
      that would disrupt the progress of the SYN2 based RDS-TCP  connection.

      Thus the arbitration scheme in rds_tcp_accept_one() should restore
      rds_tcp callbacks for the winner before setting them up for the
      new accept socket, and also make sure that conn->c_outgoing
      is set to 0 so that we do not trigger any reconnect attempts on the
      passive side of the tcp socket in the future, in conformance with
      commit c82ac7e69efe ("net/rds: RDS-TCP: only initiate reconnect attempt
      on outgoing TCP socket.")

      netfilter: nfqueue: don't use prev pointer

      Usage of -prev seems buggy.  While packet was out our hook cannot be
      removed but we have no way to know if the previous one is still valid.

      So better not use ->prev at all.  Since NF_REPEAT just asks to invoke
      same hook function again, just do so, and continue with nf_interate
      if we get an ACCEPT verdict.

      A side effect of this change is that if nf_reinject(NF_REPEAT) causes
      another REPEAT we will now drop the skb instead of a kernel loop.

      However, NF_REPEAT loops would be a bug so this should not happen anyway.

      mac80211: Do not restart scheduled scan if multiple scan plans are set

      If multiple scan plans were set for scheduled scan, do not restart
      scheduled scan on reconfig because it is possible that some scan
      plans were already completed and there is no need to run them all
      over again. Instead, notify userspace that scheduled scan stopped
      so it can configure new scan plans for scheduled scan.

      cfg80211: Add multiple scan plans for scheduled scan

      Add the option to configure multiple 'scan plans' for scheduled scan.
      Each 'scan plan' defines the number of scan cycles and the interval
      between scans. The scan plans are executed in the order they were
      configured. The last scan plan will always run infinitely and thus
      defines only the interval between scans.
      The maximum number of scan plans supported by the device and the
      maximum number of iterations in a single scan plan are advertised
      to userspace so it can configure the scan plans appropriately.

      When scheduled scan results are received there is no way to know which
      scan plan is being currently executed, so there is no way to know when
      the next scan iteration will start. This is not a problem, however.
      The scan start timestamp is only used for flushing old scan results,
      and there is no difference between flushing all results received until
      the end of the previous iteration or the start of the current one,
      since no results will be received in between.

      nl80211: allow BSS data to include CLOCK_BOOTTIME timestamp

      For location and connectivity services, userspace would often like
      to know the time when the BSS was last seen. The current "last seen"
      value is calculated in a way that makes it less useful, especially
      if the system suspended in the meantime.

      Add the ability for the driver to report a real CLOCK_BOOTTIME stamp
      that can then be reported to userspace (if present).

      Drivers wishing to use this must be converted to the new API to call
      cfg80211_inform_bss_data() or cfg80211_inform_bss_frame_data(). They
      need to ensure the reported value is accurate enough even when the
      frame might have been buffered in the device (e.g. firmware.)

      net: Pass net into defragmentation

      This is the next installment of my work to pass struct net through the
      output path so the code does not need to guess how to figure out which
      network namespace it is in, and ultimately routes can have output
      devices in another network namespace.

      In netfilter and af_packet we defragment packets in the output path,
      and there is the usual amount of confusion about how to compute which
      net we are processing the packets in.  This patchset clears that
      confusion up by explicitly passing in struct net in ip_defrag,
      ip_check_defrag, and nf_ct_frag6_gather.

      on input and the LOCAL_OUT chain on output.

      The addition of a net parameter makes it explicit which network

      ipv4/icmp: redirect messages can use the ingress daddr as source

      This patch allows configuring how the source address of ICMP
      redirect messages is selected; by default the old behaviour is
      retained, while setting icmp_redirects_use_orig_daddr force the
      usage of the destination address of the packet that caused the
      redirect.

      The new behaviour fits closely the RFC 5798 section 8.1.1, and fix the
      following scenario:

      Two machines are set up with VRRP to act as routers out of a subnet,
      they have IPs x.x.x.1/24 and x.x.x.2/24, with VRRP holding on to
      x.x.x.254/24.

      If a host in said subnet needs to get an ICMP redirect from the VRRP
      router, i.e. to reach a destination behind a different gateway, the
      source IP in the ICMP redirect is chosen as the primary IP on the
      interface that the packet arrived at, i.e. x.x.x.1 or x.x.x.2.

      The host will then ignore said redirect, due to RFC 1122 section 3.2.2.2,
      and will continue to use the wrong next-op.

      perf hists browser: Add 'm' key for context menu display

      With horizontal scrolling, the left/right arrow keys are used to scroll
      columns and ENTER/ESC keys are used to enter/exit menu.  However if
      callchain is recorded, the ENTER key is used to toggle callchain
      expansion so there's no way to display menu.  Use 'm' key to display the
      menu for this case.

      tcp: better smp listener behavior

      As promised in last patch series, we implement a better SO_REUSEPORT
      strategy, based on cpu hints if given by the application.

      We also moved sk_refcnt out of the cache line containing the lookup
      keys, as it was considerably slowing down smp operations because
      of false sharing. This was simpler than converting listen sockets
      to conventional RCU (to avoid sk_refcnt dirtying)

      net: align sk_refcnt on 128 bytes boundary

      sk->sk_refcnt is dirtied for every TCP/UDP incoming packet.
      This is a performance issue if multiple cpus hit a common socket,
      or multiple sockets are chained due to SO_REUSEPORT.

      By moving sk_refcnt 8 bytes further, first 128 bytes of sockets
      are mostly read. As they contain the lookup keys, this has
      a considerable performance impact, as cpus can cache them.

      These 8 bytes are not wasted, we use them as a place holder
      for various fields, depending on the socket type.

      Tested:
       SYN flood hitting a 16 RX queues NIC.
       TCP listener using 16 sockets and SO_REUSEPORT
       and SO_INCOMING_CPU for proper siloing.

       Could process 6.0 Mpps SYN instead of 4.2 Mpps

      net: SO_INCOMING_CPU setsockopt() support

      SO_INCOMING_CPU as added in commit 2c8c56e15df3 was a getsockopt() command
      to fetch incoming cpu handling a particular TCP flow after accept()

      This commits adds setsockopt() support and extends SO_REUSEPORT selection
      logic : If a TCP listener or UDP socket has this option set, a packet is
      delivered to this socket only if CPU handling the packet matches the 
specified
      one.

      This allows to build very efficient TCP servers, using one listener per
      RX queue, as the associated TCP listener should only accept flows handled
      in softirq by the same cpu.
      This provides optimal NUMA behavior and keep cpu caches hot.

      Note that __inet_lookup_listener() still has to iterate over the list of
      all listeners. Following patch puts sk_refcnt in a different cache line
      to let this iteration hit only shared and read mostly cache lines.

      ====================
      bpf: unprivileged

      v1-v2:
      - this set logically depends on cb patch
        "bpf: fix cb access in socket filter programs":
        http://patchwork.ozlabs.org/patch/527391/
        which is must have to allow unprivileged programs.
        Thanks Daniel for finding that issue.
      - refactored sysctl to be similar to 'modules_disabled'
      - dropped bpf_trace_printk
      - split tests into separate patch and added more tests
        based on discussion

      v1 cover letter:
      I think it is time to liberate eBPF from CAP_SYS_ADMIN.
      As was discussed when eBPF was first introduced two years ago
      the only piece missing in eBPF verifier is 'pointer leak detection'
      to make it available to non-root users.
      Patch 1 adds this pointer analysis.
      The eBPF programs, obviously, need to see and operate on kernel addresses,
      but with these extra checks they won't be able to pass these addresses
      to user space.
      Patch 2 adds accounting of kernel memory used by programs and maps.
      It changes behavoir for existing root users, but I think it needs
      to be done consistently for both root and non-root, since today
      programs and maps are only limited by number of open FDs (RLIMIT_NOFILE).
      Patch 2 accounts program's and map's kernel memory as RLIMIT_MEMLOCK.

      Unprivileged eBPF is only meaningful for 'socket filter'-like programs.
      eBPF programs for tracing and TC classifiers/actions will stay root only.

      In parallel the bpf fuzzing effort is ongoing and so far
      we've found only one verifier bug and that was already fixed.
      The 'constant blinding' pass also being worked on.
      It will obfuscate constant-like values that are part of eBPF ISA
      to make jit spraying attacks even harder.

      unpriv: add const to pointer
      unpriv: add pointer to pointer
      unpriv: neg pointer
        checks that pointer arithmetic is disallowed

      unpriv: cmp pointer with const
      unpriv: cmp pointer with pointer
        checks that comparison of pointers is disallowed
        Only one case allowed 'void *value = bpf_map_lookup_elem(..); if (value 
== 0) ...'

      unpriv: check that printk is disallowed
        since bpf_trace_printk is not available to unprivileged

      unpriv: pass pointer to helper function
        checks that pointers cannot be passed to functions that expect integers
        If function expects a pointer the verifier allows only that type of 
pointer.
        Like 1st argument of bpf_map_lookup_elem() must be pointer to map.
        (applies to non-root as well)

      unpriv: indirectly pass pointer on stack to helper function
        checks that pointer stored into stack cannot be used as part of key
        passed into bpf_map_lookup_elem()

      unpriv: mangle pointer on stack 1
      unpriv: mangle pointer on stack 2
        checks that writing into stack slot that already contains a pointer
        is disallowed

      unpriv: read pointer from stack in small chunks
        checks that < 8 byte read from stack slot that contains a pointer is
        disallowed

      unpriv: write pointer into ctx
        checks that storing pointers into skb->fields is disallowed

      unpriv: write pointer into map elem value
        checks that storing pointers into element values is disallowed
        For example:
        int bpf_prog(struct __sk_buff *skb)
        {
          u32 key = 0;
          u64 *value = bpf_map_lookup_elem(&map, &key);
          if (value)
             *value = (u64) skb;
        }
        will be rejected.

      unpriv: partial copy of pointer
        checks that doing 32-bit register mov from register containing
        a pointer is disallowed

      unpriv: pass pointer to tail_call
        checks that passing pointer as an index into bpf_tail_call
        is disallowed

      unpriv: cmp map pointer with zero
        checks that comparing map pointer with constant is disallowed

      unpriv: write into frame pointer
        checks that frame pointer is read-only (applies to root too)

      unpriv: cmp of frame pointer
        checks that R10 cannot be using in comparison

      unpriv: cmp of stack pointer
        checks that Rx = R10 - imm is ok, but comparing Rx is not

      unpriv: obfuscate stack pointer
        checks that Rx = R10 - imm is ok, but Rx -= imm is not

      bpf: charge user for creation of BPF maps and programs

      since eBPF programs and maps use kernel memory consider it 'locked' memory
      from user accounting point of view and charge it against RLIMIT_MEMLOCK 
limit.
      This limit is typically set to 64Kbytes by distros, so almost all
      bpf+tracing programs would need to increase it, since they use maps,
      but kernel charges maximum map size upfront.
      For example the hash map of 1024 elements will be charged as 64Kbyte.
      It's inconvenient for current users and changes current behavior for root,
      but probably worth doing to be consistent root vs non-root.

      Similar accounting logic is done by mmap of perf_event.

      bpf: enable non-root eBPF programs

      In order to let unprivileged users load and execute eBPF programs
      teach verifier to prevent pointer leaks.
      Verifier will prevent
      - any arithmetic on pointers
        (except R10+Imm which is used to compute stack addresses)
      - comparison of pointers
        (except if (map_value_ptr == 0) ... )
      - passing pointers to helper functions
      - indirectly passing pointers in stack to helper functions
      - returning pointer from bpf program
      - storing pointers into ctx or maps

      Spill/fill of pointers into stack is allowed, but mangling
      of pointers stored in the stack or reading them byte by byte is not.

      Within bpf programs the pointers do exist, since programs need to
      be able to access maps, pass skb pointer to LD_ABS insns, etc
      but programs cannot pass such pointer values to the outside
      or obfuscate them.

      Only allow BPF_PROG_TYPE_SOCKET_FILTER unprivileged programs,
      so that socket filters (tcpdump), af_packet (quic acceleration)
      and future kcm can use it.
      tracing and tc cls/act program types still require root permissions,
      since tracing actually needs to be able to see all kernel pointers
      and tc is for root only.

      For example, the following unprivileged socket filter program is allowed:
      int bpf_prog1(struct __sk_buff *skb)
      {
        u32 index = load_byte(skb, ETH_HLEN + offsetof(struct iphdr, protocol));
        u64 *value = bpf_map_lookup_elem(&my_map, &index);

        if (value)
        *value += skb->len;
        return 0;
      }

      but the following program is not:
      int bpf_prog1(struct __sk_buff *skb)
      {
        u32 index = load_byte(skb, ETH_HLEN + offsetof(struct iphdr, protocol));
        u64 *value = bpf_map_lookup_elem(&my_map, &index);

        if (value)
        *value += (u64) skb;
        return 0;
      }
      since it would leak the kernel address into the map.

      Unprivileged socket filter bpf programs have access to the
      following helper functions:
      - map lookup/update/delete (but they cannot store kernel pointers into 
them)
      - get_random (it's already exposed to unprivileged user space)
      - get_smp_processor_id
      - tail_call into another socket filter program
      - ktime_get_ns

      The feature is controlled by sysctl kernel.unprivileged_bpf_disabled.
      This toggle defaults to off (0), but can be set true (1).  Once true,
      bpf programs and maps cannot be accessed from unprivileged process,
      and the toggle cannot be set back to false.

      depending on whether an SD card is inserted or not.

      This patch sets LDO1 regulator to always-on.

      This patch has a side effect of fixing another issue, HDMI DDC not
      working when SD card is not inserted:

      Why this happens is that the tpd12s015 (HDMI level shifter/ESD
      protection chip) has LS_OE GPIO input, which needs to be enabled for the
      HDMI DDC to work. LS_OE comes from gpio6_28. The pin that provides
      gpio6_28 is powered by vddshv8, and vddshv8 comes from VDD_SD.

      So when SD card is not inserted, VDD_SD is disabled, and LS_OE stays
      off.

      The proper fix for the HDMI DDC issue would be to maybe have the pinctrl
      framework manage the pin specific power.

      Apparently this fixes also a third issue (copy paste from Kishon's
      patch):

      ldo1_reg in addition to being connected to the io lines is also
      connected to the card detect line. On card removal, omap_hsmmc
      driver does a regulator_disable causing card detect line to be
      pulled down. This raises a card insertion interrupt and once the
      MMC core detects there is no card inserted, it does a
      regulator disable which again raises a card insertion interrupt.
      This happens in a loop causing infinite MMC interrupts.

      ARM: EXYNOS: Fix double of_node_put() when parsing child power domains

      On each next iteration of for_each_compatible_node() the reference
      counter for current device node is already decreased by the loop
      iterator. The manual call to of_node_get() is required only on loop
      break which is not happening here.

      The double of_node_get() (with enabled CONFIG_OF_DYNAMIC) lead to
      decreasing the counter below expected, initial value.

      nvme: fix 32-bit build warning

      Compiling the nvme driver on 32-bit warns about a cast from a __u64
      variable to a pointer:

      drivers/block/nvme-core.c: In function 'nvme_submit_io':
      drivers/block/nvme-core.c:1847:4: warning: cast to pointer from integer 
of different size [-Wint-to-pointer-cast]
          (void __user *)io.addr, length, NULL, 0);

      The cast here is intentional and safe, so we can shut up the
      gcc warning by adding an intermediate cast to 'uintptr_t'.

      I had previously submitted a patch to fix this problem in the
      nvme driver, but it was accepted on the same day that two new
      warnings got added.

      For clarification, I also change the third instance of this cast
      to use uintptr_t instead of unsigned long now.

      arm64: add KASAN support

      This patch adds arch specific code for kernel address sanitizer
      (see Documentation/kasan.txt).

      1/8 of kernel addresses reserved for shadow memory. There was no
      big enough hole for this, so virtual addresses for shadow were
      stolen from vmalloc area.

      At early boot stage the whole shadow region populated with just
      one physical page (kasan_zero_page). Later, this page reused
      as readonly zero shadow for some memory that KASan currently
      don't track (vmalloc).
      After mapping the physical memory, pages for shadow memory are
      allocated and mapped.

      Functions like memset/memmove/memcpy do a lot of memory accesses.
      If bad pointer passed to one of these function it is important
      to catch this. Compiler's instrumentation cannot do this since
      these functions are written in assembly.
      KASan replaces memory functions with manually instrumented variants.
      Original functions declared as weak symbols so strong definitions
      in mm/kasan/kasan.c could replace them. Original functions have aliases
      with '__' prefix in name, so we could call non-instrumented variant
      if needed.
      Some files built without kasan instrumentation (e.g. mm/slub.c).
      Original mem* function replaced (via #define) with prefixed variants
      to disable memory access checks for such files.

      arm64: Fix MINSIGSTKSZ and SIGSTKSZ

      MINSIGSTKSZ and SIGSTKSZ for ARM64 are not correctly set in latest kernel.
      This patch fixes this issue.

      This issue is reported in LTP (testcase: sigaltstack02.c).
      Testcase failed when sigaltstack() called with stack size "MINSIGSTKSZ - 
1"
      Since in Glibc-2.22, MINSIGSTKSZ is set to 5120 but in kernel
      it is set to 2048 so testcase gets failed.

      Testcase Output:
      sigaltstack02 1  TPASS  :  stgaltstack() fails, Invalid Flag 
value,errno:22
      sigaltstack02 2  TFAIL  :  sigaltstack() returned 0, expected -1,errno:12

      arm64: errata: use KBUILD_CFLAGS_MODULE for erratum #843419

      Commit df057cc7b4fa ("arm64: errata: add module build workaround for
      erratum #843419") sets CFLAGS_MODULE to ensure that the large memory
      model is used by the compiler when building kernel modules.

      However, CFLAGS_MODULE is an environment variable and intended to be
      overridden on the command line, which appears to be the case with the
      Ubuntu kernel packaging system, so use KBUILD_CFLAGS_MODULE instead.

      Linux that maps nicely onto the arm64 memory model, including the new
      ARMv8.1 atomic instructions.

      This patch hooks up the API to our relaxed atomic instructions, rather
      than have them all expand to the full-barrier variants as they do
      currently.

      writeback: fix incorrect calculation of available memory for memcg domains

      For memcg domains, the amount of available memory was calculated as

       min(the amount currently in use + headroom according to memcg,
           total clean memory)

      This isn't quite correct as what should be capped by the amount of
      clean memory is the headroom, not the sum of memory in use and
      headroom.  For example, if a memcg domain has a significant amount of
      dirty memory, the above can lead to a value which is lower than the
      current amount in use which doesn't make much sense.  In most
      circumstances, the above leads to a number which is somewhat but not
      drastically lower.

      As the amount of memory which can be readily allocated to the memcg
      domain is capped by the amount of system-wide clean memory which is
      not already assigned to the memcg itself, the number we want is

       the amount currently in use +
       min(headroom according to memcg, clean memory elsewhere in the system)

      This patch updates mem_cgroup_wb_stats() to return the number of
      filepages and headroom instead of the calculated available pages.
      mdtc_cap_avail() is renamed to mdtc_calc_avail() and performs the
      above calculation from file, headroom, dirty and globally clean pages.

      v2: Dummy mem_cgroup_wb_stats() implementation wasn't updated leading
          to build failure when !CGROUP_WRITEBACK.  Fixed.

      writeback: memcg dirty_throttle_control should be initialized with 
wb->memcg_completions

      MDTC_INIT() is used to initialize dirty_throttle_control for memcg
      domains.  It used DTC_INIT_COMMON() to initialized mdtc->wb and
      ->wb_completions which is incorrect as DTC_INIT_COMMON() sets the
      latter to wb->completions instead of wb->memcg_completions.  This can
      lead to wildly incorrect results when calculating the proportion of
      dirty memory the memcg domain should get.

      Remove DTC_INIT_COMMON() and update MDTC_INIT() to initialize
      mdtc->wb_completions to wb->memcg_completions.

      writeback: bdi_writeback iteration must not skip dying ones

      bdi_for_each_wb() is used in several places to wake up or issue
      writeback work items to all wb's (bdi_writeback's) on a given bdi.
      The iteration is performed by walking bdi->cgwb_tree; however, the
      tree only indexes wb's which are currently active.

      For example, when a memcg gets associated with a different blkcg, the
      old wb is removed from the tree so that the new one can be indexed.
      The old wb starts dying from then on but will linger till all its
      inodes are drained.  As these dying wb's may still host dirty inodes,
      writeback operations which affect all wb's must include them.
      bdi_for_each_wb() skipping dying wb's led to sync(2) missing and
      failing to sync the inodes belonging to those wb's.

      This patch adds a RCU protected @bdi->wb_list which lists all wb's
      beloinging to that bdi.  wb's are added on creation and removed on
      release rather than on the start of destruction.  bdi_for_each_wb()
      usages are replaced with list_for_each[_continue]_rcu() iterations
      over @bdi->wb_list and bdi_for_each_wb() and its helpers are removed.

      v2: Updated as per Jan.  last_wb ref leak in bdi_split_work_to_wbs()
          fixed and unnecessary list head severing in cgwb_bdi_destroy()
          removed.

      svcrdma: Fix NFS server crash triggered by 1MB NFS WRITE

      Now that the NFS server advertises a maximum payload size of 1MB
      for RPC/RDMA again, it crashes in svc_process_common() when NFS
      client sends a 1MB NFS WRITE on an NFS/RDMA mount.

      The server has set up a 259 element array of struct page pointers
      in rq_pages[] for each incoming request. The last element of the
      array is NULL.

      When an incoming request has been completely received,
      rdma_read_complete() attempts to set the starting page of the
      incoming page vector:

        rqstp->rq_arg.pages = &rqstp->rq_pages[head->hdr_count];

      and the page to use for the reply:

        rqstp->rq_respages = &rqstp->rq_arg.pages[page_no];

      But the value of page_no has already accounted for head->hdr_count.
      Thus rq_respages now points past the end of the incoming pages.

      For NFS WRITE operations smaller than the maximum, this is harmless.
      But when the NFS WRITE operation is as large as the server's max
      payload size, rq_respages now points at the last entry in rq_pages,
      which is NULL.

      netfilter: bridge: avoid unused label warning

      With the ARM mini2440_defconfig, the bridge netfilter code gets
      built with both CONFIG_NF_DEFRAG_IPV4 and CONFIG_NF_DEFRAG_IPV6
      disabled, which leads to a harmless gcc warning:

      net/bridge/br_netfilter_hooks.c: In function 'br_nf_dev_queue_xmit':
      net/bridge/br_netfilter_hooks.c:792:2: warning: label 'drop' defined but 
not used [-Wunused-label]

      This gets rid of the warning by cleaning up the code to avoid
      the respective #ifdefs causing this problem, and replacing them
      with if(IS_ENABLED()) checks. I have verified that the resulting
      object code is unchanged, and an additional advantage is that
      we now get compile coverage of the unused functions in more
      configurations.

      from the local table, but there, the fib_info's nh->nh_scope =

                if (!nh->nh_dev)

        if (dev_match || flags & XT_RPFILTER_LOOSE)
                return FIB_RES_NH(res).nh_scope <= RT_SCOPE_HOST;

      if nh->nh_scope > RT_SCOPE_HOST, it will fail. --accept-local option
      will never be passed.

      it seems the test is bogus and can be removed to fix this issue.

        if (dev_match || flags & XT_RPFILTER_LOOSE)

      arm64/efi: isolate EFI stub from the kernel proper

      Since arm64 does not use a builtin decompressor, the EFI stub is built
      into the kernel proper. So far, this has been working fine, but actually,
      since the stub is in fact a PE/COFF relocatable binary that is executed
      at an unknown offset in the 1:1 mapping provided by the UEFI firmware, we
      should not be seamlessly sharing code with the kernel proper, which is a
      position dependent executable linked at a high virtual offset.

      So instead, separate the contents of libstub and its dependencies, by
      putting them into their own namespace by prefixing all of its symbols
      with __efistub. This way, we have tight control over what parts of the
      kernel proper are referenced by the stub.

      netfilter: conntrack: fix crash on timeout object removal

      The object and module refcounts are updated for each conntrack template,
      however, if we delete the iptables rules and we flush the timeout
      database, we may end up with invalid references to timeout object that
      are just gone.

      Resolve this problem by setting the timeout reference to NULL when the
      custom timeout entry is removed from our base. This patch requires some
      RCU trickery to ensure safe pointer handling.

      This handling is similar to what we already do with conntrack helpers,
      the idea is to avoid bumping the timeout object reference counter from
      the packet path to avoid the cost of atomic ops.

      x86/microcode/amd: Do not overwrite final patch levels

      A certain number of patch levels of applied microcode should not
      be overwritten by the microcode loader, otherwise bad things
      will happen.

      Check those and abort update if the current core has one of
      those final patch levels applied by the BIOS. 32-bit needs
      special handling, of course.

      x86/microcode/amd: Extract current patch level read to a function

      Pave the way for checking the current patch level of the
      microcode in a core. We want to be able to do stuff depending on
      the patch level - in this case decide whether to update or not.
      But that will be added in a later patch.

      Drop unused local var uci assignment, while at it.

      Integrate a fix for 32-bit and CONFIG_PARAVIRT from Takashi Iwai:

       Use native_rdmsr() in check_current_patch_level() because with
       CONFIG_PARAVIRT enabled and on 32-bit, where we run before
       paging has been enabled, we cannot deref pv_info yet. Or we
       could, but we'd need to access its physical address. This way of
       fixing it is simpler. See:

         https://bugzilla.suse.com/show_bug.cgi?id=943179 for the background.

      x86/ras/mce_amd_inj: Inject bank 4 errors on the NBC

      Bank 4 MCEs are logged and reported only on the node base core
      (NBC) in a socket. Refer to the D18F3x44[NbMcaToMstCpuEn] field
      in Fam10h and later BKDGs. The node base core (NBC) is the
      lowest numbered core in the node.

      This patch ensures that we inject the error on the NBC for bank
      4 errors. Otherwise, triggering #MC or APIC interrupts on a core
      which is not the NBC would not have any effect on the system,
      i.e. we would not see any relevant output on kernel logs for the
      error we just injected.

      even though the 'flags' attribute has been updated correctly:

      This is because userspace keeps writing the remaining buffer
      until it encounters an error.

      However, the input as a whole is wrong and we should not be

      to return -EINVAL immediately on bad input strings.

      ovl: fix open in stacked overlay

      If two overlayfs filesystems are stacked on top of each other, then we 
need

      I guess d_backing_inode() is supposed to do that.  But currently it 
doesn't
      and that functionality is open coded in vfs_open().  This is now copied
      into ovl_d_select_inode() to fix this regression.

      ovl: fix dentry reference leak

      In ovl_copy_up_locked(), newdentry is leaked if the function exits through
      out_cleanup as this just to out after calling ovl_cleanup() - which 
doesn't
      actually release the ref on newdentry.

      The out_cleanup segment should instead exit through out2 as certainly
      newdentry leaks - and possibly upper does also, though this isn't caught
      given the catch of newdentry.

      Without this fix, something like the following is seen:

        BUG: Dentry ffff880023e9eb20{i=f861,n=#ffff880023e82d90} still in use 
(1) [unmount of tmpfs tmpfs]
        BUG: Dentry ffff880023ece640{i=0,n=bigfile}  still in use (1) [unmount 
of tmpfs tmpfs]

      when unmounting the upper layer after an error occurred in copyup.

      An error can be induced by creating a big file in a lower layer with
      something like:

        dd if=/dev/zero of=/lower/a/bigfile bs=65536 count=1 seek=$((0xf000))

      to create a large file (4.1G).  Overlay an upper layer that is too small
      (on tmpfs might do) and then induce a copy up by opening it writably.

      efifb: Add support for 64-bit frame buffer addresses

      The EFI Graphics Output Protocol uses 64-bit frame buffer addresses
      but these get truncated to 32-bit by the EFI boot stub when storing
      the address in the 'lfb_base' field of 'struct screen_info'.

      Add a 'ext_lfb_base' field for the upper 32-bits of the frame buffer
      address and set VIDEO_TYPE_CAPABILITY_64BIT_BASE when the field is
      useable.

      It turns out that the reason no one has required this support so far
      is that there's actually code in tianocore to "downgrade" PCI
      resources that have option ROMs and 64-bit BARS from 64-bit to 32-bit
      to cope with legacy option ROMs that can't handle 64-bit addresses.
      The upshot is that basically all GOP devices in the wild use a 32-bit
      frame buffer address.

      Still, it is possible to build firmware that uses a full 64-bit GOP
      frame buffer address. Chad did, which led to him reporting this issue.

      Add support in anticipation of GOP devices using 64-bit addresses more
      widely, and so that efifb works out of the box when that happens.

      drivers/firmware: Make efi/esrt.c driver explicitly non-modular

      The Kconfig for this driver is currently hidden with:

      config EFI_ESRT
              bool

      ...meaning that it currently is not being built as a module by anyone.
      Lets remove the modular code that is essentially orphaned, so that
      when reading the driver there is no doubt it is builtin-only.

      Since module_init translates to device_initcall in the non-modular
      case, the init ordering remains unchanged with this commit.

      We leave some tags like MODULE_AUTHOR for documentation purposes.

      We don't replace module.h with init.h since the file already has that.

      net: HNS: fix MDIO dependencies

      The newly introduced HNS_MDIO Kconfig symbol selects 'MDIO', but
      that is the wrong symbol as the code used by this driver is
      provided by PHYLIB rather than the MDIO driver. Also, there is
      no need to make this driver user selectable, because it is already
      selected by all drivers that need it.

      This changes the Kconfig file to select the correct library, and
      to make the option silent.

      sfc: fully reset if MC_REBOOT event received without warm_boot_count 
increment

      On EF10, MC_CMD_VPORT_RECONFIGURE can cause a CODE_MC_REBOOT event
      to be sent to a function without incrementing the (adapter-wide)
      warm_boot_count.  In this case, the reboot is not detected by the
      loop on efx_mcdi_poll_reboot(), so prepare for recovery from an MC
      reboot anyway.  When this codepath is run, the MC has always just
      rebooted, so this recovery is valid.

      The loop on efx_mcdi_poll_reboot() is still required for other MC
      reboot cases, so that actions in response to an MC reboot are
      performed, such as clearing locally calculated statistics.
      Siena NICs are unaffected by this change as the above scenario
      does not apply.

      Scott Feldman says:

      ====================
      switchdev: push bridge ageing_time attribute down

      Push bridge-level attributes down to switchdev drivers.  This patchset
      adds the infrastructure and then pushes, as an example, ageing_time 
attribute
      down from bridge to switchdev (rocker) driver.  Add some range-checking
      for ageing_time.

      RTNETLINK answers: Numerical result out of range

      Up until now, switchdev attrs where port-level attrs, so the netdev used 
in
      switchdev_attr_set() would be a switch port or bond of switch ports.  With
      bridge-level attrs, the netdev passed to switchdev_attr_set() is the 
bridge
      netdev.  The same recusive algo is used to visit the leaves of the stacked
      drivers to set the attr, it's just in this case we start one layer higher 
in
      the stack.  One note is not all ports in the bridge may support setting a
      bridge-level attribute, so rather than failing the entire set, we'll skip 
over
      those ports returning -EOPNOTSUPP.

      v2->v3: Per Jiri review: push only ageing_time attr down at this time, and
      don't pass raw bridge IFLA_BR_* values; rather use new switchdev attr ID 
for
      ageing_time.

      Thus this patch introduces a new test which manipulates the

      expect.

      sched, tracing: Stop/start critical timings around the idle=poll idle loop

      When using idle=poll, the preemptoff tracer is always showing
      the idle task as the culprit for long latencies. That happens
      because critical timings are not stopped before idle loop. This
      patch stops critical timings before entering the idle loop,
      starting it again after the idle loop.

      This problem does not affect the irqsoff tracer because
      interruptions are enabled before entering the idle loop.

      Currently OF bios load fails for a few reasons:
       - checksum failure
       - bios size too small
       - no PCIR header
       - bios length not a multiple of 4

      In this change, we resolve all of the above by ignoring any checksum
      failures (since OF VBIOS tends not to have a checksum), and faking the
      PCIR data when loading from OF.

      timers: Use __fls in apply_slack()

      In apply_slack(), find_last_bit() is applied to a bitmask consisting
      of precisely BITS_PER_LONG bits. Since mask is non-zero, we might as
      well eliminate the function call and use __fls() directly. On x86_64,
      this shaves 23 bytes of the only caller, mod_timer().

      This also gets rid of Coverity CID 1192106, but that is a false
      positive: Coverity is not aware that mask != 0 implies that
      find_last_bit will not return BITS_PER_LONG.

      tcp: fix RFS vs lockless listeners

      Before recent TCP listener patches, we were updating listener
      sk->sk_rxhash before the cloning of master socket.

      children sk_rxhash was therefore correct after the normal 3WHS.

      But with lockless listener, we no longer dirty/change listener sk_rxhash
      as it would be racy.

      We need to correctly update the child sk_rxhash, otherwise first data
      packet wont hit correct cpu if RFS is used.

      net: synack packets can be attached to request sockets

      selinux needs few changes to accommodate fact that SYNACK messages
      can be attached to a request socket, lacking sk_security pointer

      (Only syncookies are still attached to a TCP_LISTEN socket)

      Adds a new sk_listener() helper, and use it in selinux and sch_fq

      Fixes: ca6fb0651883 ("tcp: attach SYNACK messages to request sockets 
instead of listener")

      cxgb4: Enhance driver to update FW, when FW is too old

      t4_check_fw_version() can return several error codes (-EINVAL, -EBUSY,
      -EAGAIN). The present code sets the adapter state to UNINIT only if its
      an EFAULT. In all the error cases set the adapter to uninitialized state.

      In t4_check_fw_version() if call to t4_get_fw_version() fails, repeat the
      operation a few times before returning failure.

      bpf: fix cb access in socket filter programs

      eBPF socket filter programs may see junk in 'u32 cb[5]' area,
      since it could have been used by protocol layers earlier.

      For socket filter programs used in af_packet we need to clean
      20 bytes of skb->cb area if it could be used by the program.
      For programs attached to TCP/UDP sockets we need to save/restore
      these 20 bytes, since it's used by protocol layers.

      Remove SK_RUN_FILTER macro, since it's no longer used.

      Long term we may move this bpf cb area to per-cpu scratch, but that
      requires addition of new 'per-cpu load/store' instructions,
      so not suitable as a short term fix.

      genirq: Add flag to force mask in disable_irq[_nosync]()

      If an irq chip does not implement the irq_disable callback, then we
      use a lazy approach for disabling the interrupt. That means that the
      interrupt is marked disabled, but the interrupt line is not
      immediately masked in the interrupt chip. It only becomes masked if
      the interrupt is raised while it's marked disabled. We use this to avoid
      possibly expensive mask/unmask operations for common case operations.

      Unfortunately there are devices which do not allow the interrupt to be
      disabled easily at the device level. They are forced to use
      disable_irq_nosync(). This can result in taking each interrupt twice.

      Instead of enforcing the non lazy mode on all interrupts of a irq
      chip, provide a settings flag, which can be set by the driver for that
      particular interrupt line.

      efi: Use the generic efi.memmap instead of 'memmap'

      Guenter reports that commit:

        7bf793115dd9 ("efi, x86: Rearrange efi_mem_attributes()")

      breaks the IA64 compilation with the following error:

        drivers/built-in.o: In function `efi_mem_attributes': (.text+0xde962): 
undefined reference to `memmap'

      Instead of using the (rather poorly named) global variable
      'memmap' which doesn't exist on IA64, use efi.memmap which
      points to the 'memmap' object on x86 and arm64 and which is NULL
      for IA64.

      The fact that efi.memmap is NULL for IA64 is OK because IA64
      provides its own implementation of efi_mem_attributes().

      namei: results of d_is_negative() should be checked after dentry 
revalidation

      Leandro Awa writes:
       "After switching to version 4.1.6, our parallelized and distributed
        workflows now fail consistently with errors of the form:

        T34: ./regex.c:39:22: error: config.h: No such file or directory

        From our 'git bisect' testing, the following commit appears to be the
        possible cause of the behavior we've been seeing: commit 766c4cbfacd8"

      Al Viro says:
       "What happens is that 766c4cbfacd8 got the things subtly wrong.

        We used to treat d_is_negative() after lookup_fast() as "fall with
        ENOENT".  That was wrong - checking ->d_flags outside of ->d_seq
        protection is unreliable and failing with hard error on what should've
        fallen back to non-RCU pathname resolution is a bug.

        Unfortunately, we'd pulled the test too far up and ran afoul of
        another kind of staleness.  The dentry might have been absolutely
        stable from the RCU point of view (and we might be on UP, etc), but
        stale from the remote fs point of view.  If ->d_revalidate() returns
        "it's actually stale", dentry gets thrown away and the original code
        wouldn't even have looked at its ->d_flags.

        What we need is to check ->d_flags where 766c4cbfacd8 does (prior to
        ->d_seq validation) but only use the result in cases where we do not
        discard this dentry outright"

      arm/arm64: KVM: Only allow 64bit hosts to build VGICv3

      Hardware virtualisation of GICv3 is only supported by 64bit hosts for
      the moment. Some VGICv3 bits are missing from the 32bit side, and this
      patch allows to still be able to build 32bit hosts when CONFIG_ARM_GIC_V3
      is selected.

      To this end, we introduce a new option, CONFIG_KVM_ARM_VGIC_V3, that is
      only enabled on the 64bit side. The selection is done unconditionally
      because CONFIG_ARM_GIC_V3 is always enabled on arm64.

      ARM: add 32bit support to GICv3

      Implement the system and memory-mapped register accesses in
      asm/arch_gicv3.h for 32bit architectures.

      This patch is a straightforward translation of the arm64 header. 64bit
      accesses are done in two times and don't need atomicity: TYPER is
      read-only, and the upper-word of IROUTER is always zero on 32bit
      architectures.

      irqchip/gic-v3: Specialize readq and writeq accesses

      On 32bit platforms, we cannot assure that an I/O ldrd or strd will be
      done atomically. Besides, an hypervisor would be unable to emulate such
      accesses.
      In order to allow the AArch32 version of the driver to split them into
      two 32bit accesses while keeping the requirement for atomic writes, this
      patch specializes the IROUTER and TYPER accesses.
      Since the latter is an ID register, it won't need to be read atomically,
      but we still avoid future confusion by using gic_read_typer instead of a
      generic gic_readq.

      irqchip/gic-v3: Change unsigned types for AArch32 compatibility

      This patch does a few simple compatibility-related changes:
      - change the system register access prototypes to their actual size,
      - homogenise mpidr accesses with unsigned long,
      - force the 64bit register values to unsigned long long.

      Note: the list registers are 64bit on GICv3, but the AArch32 vGIC driver
      will need to split their values into two 32bit registers: LRn and LRCn.

      irqchip/gic-v2m: Add workaround for APM X-Gene GICv2m erratum

      APM X-Gene GICv2m implementation has an erratum where the
      MSI data needs to be the offset from the spi_start in order to
      trigger the correct MSI interrupt. This is different from the
      standard GICv2m implementation where the MSI data is the absolute
      value within the range from spi_start to (spi_start + num_spis)
      of each v2m frame.

      This patch reads MSI_IIDR register (present in all GICv2m
      implementations) to identify X-Gene GICv2m implementation and
      apply workaround to change the data portion of MSI vector.

      explodes very early.

      Work around this by testing if the SRE bit sticks or not. If it doesn't,
      abort the GICv3 setup, and pray that the firmware has passed a DT that
      doesn't contain a GICv3 node.

      Fix this incompatibility by requiring newer userspace code, that can
      cope with "Overflow", request the persistent store with overflow support
      by using "PO" (Persistent with Overflow) for the snapshot store type.

      The device tree node name is typically "interrupt-controller", which is
      rather useless when used in printk messages and irq chip names for
      identification purposes. Use the driver name "sunxi-nmi" instead.

      While at it move the identifier from pr_err() calls to the pr_fmt macro.

      Also remove the "__func__" identifier from the error message in the
      interrupt type setting callback, sunxi_sc_nmi_set_type(). The driver
      name in the pr_fmt macro should be enough.

      genirq: Allow migration of chained interrupts by installing default action

      When a CPU is offlined all interrupts that have an action are migrated to
      other still online CPUs. However, if the interrupt has chained handler
      installed this is not done. Chained handlers are used by GPIO drivers 
which
      support interrupts, for instance.

      When the affinity is not corrected properly we end up in situation where
      most interrupts are not arriving to the online CPUs anymore. For example 
on
      Intel Braswell system which has SD-card card detection signal connected to
      a GPIO the IO-APIC routing entries look like below after CPU1 is offlined:

        pin30, enabled , level, low , V(52), IRR(0), S(0), logical , D(03), M(1)
        pin31, enabled , level, low , V(42), IRR(0), S(0), logical , D(03), M(1)
        pin32, enabled , level, low , V(62), IRR(0), S(0), logical , D(03), M(1)
        pin5b, enabled , level, low , V(72), IRR(0), S(0), logical , D(03), M(1)

      The problem here is that the destination mask still contains both CPUs 
even
      if CPU1 is already offline. This means that the IO-APIC still routes
      interrupts to the other CPU as well.

      We solve the problem by providing a default action for chained interrupts.
      This action allows the migration code to correct affinity (as it finds
      desc->action != NULL).

      Also make the default action handler to emit a warning if for some reason 
a
      chained handler ends up calling it.

      arm64: fix a migrating irq bug when hotplug cpu

      When cpu is disabled, all irqs will be migratged to another cpu.
      In some cases, a new affinity is different, the old affinity need
      to be updated and if irq_set_affinity's return value is 
IRQ_SET_MASK_OK_DONE,
      the old affinity can not be updated. Fix it by using irq_do_set_affinity.

      And migrating interrupts is a core code matter, so use the generic
      function irq_migrate_all_off_this_cpu() to migrate interrupts in
      kernel/irq/migration.c.

      iommu/amd: Fix NULL pointer deref on device detach

      When a device group is detached from its domain, the iommu
      core code calls into the iommu driver to detach each device
      individually.

      Before this functionality went into the iommu core code, it
      was implemented in the drivers, also in the AMD IOMMU
      driver as the device alias handling code.

      This code is still present, as there might be aliases that
      don't exist as real PCI devices (and are therefore invisible
      to the iommu core code).

      Unfortunatly it might happen now, that a device is unbound
      multiple times from its domain, first by the alias handling
      code and then by the iommu core code (or vice verca).

      This ends up in the do_detach function which dereferences
      the dev_data->domain pointer. When the device is already
      detached, this pointer is NULL and we get a kernel oops.

      Removing the alias code completly is not an option, as that
      would also remove the code which handles invisible aliases.
      The code could be simplified, but this is too big of a
      change outside the merge window.

      For now, just check the dev_data->domain pointer in
      do_detach and bail out if it is NULL.

      Russell noted that "the TWD local timers are unable to wake up the CPU
      when it is placed into a low power mode".

      However, some platforms do not stop the TWD block in low-power mode,
      and can thus use the TWD timer in one-shot mode, without setting up
      a broadcast device.

      Make the driver check for the "always-on" boolean property, and set
      the CLOCK_EVT_FEAT_C3STOP flag accordingly.

      Paul Gortmaker says:

      ====================
      make non-modular code explicitly non-modular

      [v2: drop m68k patches that Geert converted to modules; add one ARM
       driver patch ; update net-next baseline to today; switch to ARM
       for build testing.]

      In a previous merge window, we made changes to allow better
      delineation between modular and non-modular code in commit
      0fd972a7d91d6e15393c449492a04d94c0b89351 ("module: relocate module_init
      from init.h to module.h").  This allows us to now ensure module code
      looks modular and non-modular code does not accidentally look modular
      just to avoid suffering build breakage.

      Here we target code that is, by nature of their Makefile and/or
      Kconfig settings, only available to be built-in, but implicitly
      presenting itself as being possibly modular by way of using modular
      headers, macros, and functions.

      The goal here is to remove that illusion of modularity from these
      files, but in a way that leaves the actual runtime unchanged.
      In doing so, we remove code that has never been tested and adds
      no value to the tree.  And we continue the process of expecting a
      level of consistency between the Kconfig/Makefile of code and the
      code in use itself.

      Fortuntately the net subsystem has relatively few instances, given
      the overall amount of code and drivers it contains.  For comparison
      there are over 300 instances tree wide, resulting in a possible net
      removal of on the order of 5000 lines of unused code.

      Build tested on net-next from today, on ARM, since that is the arch
      where the one ethernet driver changed here is available.

      readability and/or simplicity because these functions only use one
      or zero as their return value.

      No functional changes.

      In preparation to handling system errors at the mlx5_core level, change 
the
      interface of cmd_work_handler to accept a 64 bit argument for the vector.

      This allows to encode a flag that signifies when the handler is called
      as a result of a driver logic that wishes to terminate commands that
      the hardware may not be able to terminate. Such command completions
      are detected at the handler and proper return status is encoded.

      To be able to terminate page handler commands, we make sure to set
      the corresponding bit in the bitmask.

      Intel Wired LAN Driver Updates 2015-10-08

      This series contains updates to i40e and i40evf only (again).

      Jesse fixes an issue where the driver was issuing a WARN_ON during ring
      size changes because the code was cloning the rx_ring struct but not
      zeroing out the pointers before allocating new memory, so simply zero
      out the pointers.  Also reduced the function call overhead by moving
      the interrupt enable function by moving it to the header file, which it
      in turn allows us to inline it.  Also does a thorough job of code
      cleanup to fix spaces after declarations, remove unnecessary braces
      and breaks, remove another __func__ use and general code tidiness.

      Mitch adds mover verbose error messages when the number of supported VFs
      is reported in driver init and it different from the number reported in
      config space.  Updated the VF driver to now detect a reset with the
      VF_ARQLEN register since the enable bit is cleared when the VF is reset
      and it stays cleared until the VF driver processes the reset and
      re-enables the admin queue which is more reliable than using the
      VFGEN_RSTAT as previously.

      Neerav adds parsing for CEE DCBx TLVs from the LLDP MIB since there is
      a need to get the CEE DesiredCfg Tx by firmware and DCB configuration
      Rx from peer for debug and other application purposes.

      Carolyn fixes a problem where the PF's Flow Director filter table would
      have an entry that the hardware was unable to add, when this occurs an
      invalid entry gets replayed and a valid one is lost.

      Matt fixes an issue where multiple link up messages can be logged
      resulting from admin queue link status timing when link properties are
      changed.

      Shannon adds the ability to control the period link polling through
      ethtool to be able to switch it off and on for debugging link issues.

      Serey explicitly assigns the enum index for each VSI type so that the PF
      and VF always reference to the same VSI type event if the enum lists
      are different.

      dm cache: fix NULL pointer when switching from cleaner policy

      The cleaner policy doesn't make use of the per cache block hint space in
      the metadata (unlike the other policies).  When switching from the
      cleaner policy to mq or smq a NULL pointer crash (in dm_tm_new_block)
      was observed.  The crash was caused by bugs in dm-cache-metadata.c
      when trying to skip creation of the hint btree.

      The minimal fix is to change hint size for the cleaner policy to 4 bytes
      (only hint size supported).

      ARC is the only arch with unsigned long type (vs. struct page *).
      Historically this was done to avoid the page_address() calls in various
      arch hooks which need to get the virtual/logical address of the table.

      Some arches alternately define it as pte_t *, and is as efficient as
      unsigned long (generated code doesn't change)

      ath: fix DFS timestamp wraparound reset condition

      The DFS pattern detector ought to reset the
      detector lines when a pulse is added with
      lower time stamp than the previous (which
      indicates a TSF restart).

      This did not work so far and is fixed with
      this patch.

      The modification does not change detection
      performance within the driver, since it
      only ensures early reset (which is later
      performed by the PRI detectors anyway).
      It is relevant for synthetic tests and
      statistical evaluations, where millions
      of pulse patterns are processed and an
      early reset helps reducing load.

      to the actual hardware reset as the recovery flow would
      make additional unnecessary reset.

      wil6210: dump firmware memory when firmware crashes

      When firmware crashes, just before firmware recovery,
      dump the firmware memory to a devcoredump device.
      The resulting dump can be read from user space to be used
      in offline crash analysis.

      wil6210: ratelimit Tx error message

      Situations observed when IP stack schedules lots of

      for example). In this case, dmesg bloated with error
      message "FW not connected", printed for every frame.

      wil6210: Add proper handling for invalid frames on Rx

      On Rx, when invalid frame is received and dropped,
      reaping of next frames from Rx ring is stopped.

      This stops NAPI polling and re-enables the Rx interrupt.

      However, in cases where no more frames received,
      interrupt will not be triggered and rest of Rx frames
      will not be processed.

      Skip bad frames and continue to reap Rx packets when
      such frames are encountered, and add statistics for
      such frames for debug.

      ath10k: optimize ce_lock on post rx buffer processing

      After processing received packets from copy engine, host will allocate
      new buffer and queue them back to copy engine ring for further
      packet reception. On post rx processing path, skb allocation and
      dma mapping are unnecessarily handled within ce_lock. This is affecting
      peak throughput and also causing more CPU consumption. Optimize this
      by acquiring ce_lock only when accessing copy engine ring and moving
      skb allocation out of ce_lock.

      In AP148 platform with QCA99x0 in conducted environment, UDP uplink peak
      throughput is improved from ~1320 Mbps to ~1450 Mbps and TCP uplink peak
      throughput is increased from ~1240 Mbps (70% host CPU load) to ~1300 Mbps
      (71% CPU load). Similarly ~40Mbps improvement is observed in downlink
      path.

      x86/entry/compat: Implement opportunistic SYSRETL for compat syscalls

      If CS, SS and IP are as expected and FLAGS is compatible with
      SYSRETL, then return from fast compat syscalls (both SYSCALL and
      SYSENTER) using SYSRETL.

      Unlike native 64-bit opportunistic SYSRET, this is not invisible
      to user code: RCX and R8-R15 end up in a different state than
      shown saved in pt_regs.  To compensate, we only do this when
      returning to the vDSO fast syscall return path.  This won't
      interfere with syscall restart, as we won't use SYSRETL when
      returning to the INT80 restart instruction.

      x86/entry/64/compat: Set up full pt_regs for all compat syscalls

      This is conceptually simpler.  More importantly, it eliminates
      the PTREGSCALL and execve stubs, which were not compatible with
      the C ABI.  This means that C code can call through the compat
      syscall table.

      The execve stubs are a bit subtle.  They did two things: they
      cleared some registers and they forced slow-path return.
      Neither is necessary any more: elf_common_init clears the extra
      registers and start_thread calls force_iret().

      x86/vdso/32: Save extra registers in the INT80 vsyscall path

      The goal is to integrate the SYSENTER and SYSCALL32 entry paths
      with the INT80 path.  SYSENTER clobbers ESP and EIP.  SYSCALL32
      clobbers ECX (and, invisibly, R11).  SYSRETL (long mode to
      compat mode) clobbers ECX and, invisibly, R11.  SYSEXIT (which
      we only need for native 32-bit) clobbers ECX and EDX.

      This means that we'll need to provide ESP to the kernel in a
      register (I chose ECX, since it's only needed for SYSENTER) and
      we need to provide the args that normally live in ECX and EDX in
      memory.

      The epilogue needs to restore ECX and EDX, since user code
      relies on regs being preserved.

      We don't need to do anything special about EIP, since the kernel
      already knows where we are.  The kernel will eventually need to
      know where int $0x80 lands, so add a vdso_image entry for it.

      The only user-visible effect of this code is that ptrace-induced
      changes to ECX and EDX during fast syscalls will be lost.  This
      is already the case for the SYSENTER path.

      x86/vdso: Replace hex int80 CFI annotations with GAS directives

      Maintaining the current CFI annotations written in R'lyehian is
      difficult for most of us.  Translate them to something a little
      closer to English.

      This will remove the CFI data for kernels built with extremely
      old versions of binutils.  I think this is a fair tradeoff for
      the ability for mortals to edit the asm.

dwarf annotations")

      removed all the manual DWARF annotations outside the vDSO.  It also 
removed
      the macros we used for the manual annotations.

      Re-add these macros so that we can clean up the vDSO annotations.

      drm: Fix locking for sysfs dpms file

      With atomic drivers we need to make sure that (at least in general)
      property reads hold the right locks. But the legacy dpms property is
      special and can be read locklessly. Since userspace loves to just
      randomly look at that all the time (like with "status") do that.

      To make it clear that we play tricks use the READ_ONCE compiler
      barrier (and also for paranoia).

      Note that there's not really anything bad going on since even with the
      new atomic paths we eventually end up not chasing any pointers (and
      hence possibly freed memory and other fun stuff). The locking WARNING
      has been added in

      i40evf: detect reset more reliably

      Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught
      with peril. It's entirely too easy to miss a reset because none of the
      bits are sticky. By the time the VF driver reads the register, the reset
      may have been processed and cleaned up by the PF driver, leaving the
      register in the same state that it was before the reset.

      Instead, detect a reset with the VF_ARQLEN register. When the VF is
      reset, the enable bit in this register is cleared, and it stays cleared
      until the VF driver processes the reset and re-enables the admin queue.

      Because we now deal with multiple registers in the reset and watchdog
      tasks, rename the rstat_val variable to reg_val.

      Ran into an issue where PF's VSI type list was different from VF's,
      which was resulted in different enum index. The VSI type list can
      be different depending on what build flag is used for PF and VF.

      The change is to explicitly assign enum index for each VSI type
      so that PF and VF always reference to the same VSI type event if the
      enum lists are different.

      The reason for the crash is that the newly added code in raid1d moves the
      list from conf->bio_end_io_list to tmp, then tests if tmp is non-empty and
      then incorrectly pops the bio from conf->bio_end_io_list (which is empty
      because the list was alrady moved).

      Raid-10 has a similar bug.

      powerpc/powernv: Panic on unhandled Machine Check

      All unrecovered machine check errors on PowerNV should cause an
      immediate panic. There are 2 reasons that this is the right policy:
      it's not safe to continue, and we're already trying to reboot.

      Firstly, if we go through the recovery process and do not successfully
      recover, we can't be sure about the state of the machine, and it is
      not safe to recover and proceed.

      Linux knows about the following sources of Machine Check Errors:
      - Uncorrectable Errors (UE)
      - Effective - Real Address Translation (ERAT)
      - Segment Lookaside Buffer (SLB)
      - Translation Lookaside Buffer (TLB)
      - Unknown/Unrecognised

      In the SLB, TLB and ERAT cases, we can further categorise these as
      parity errors, multihit errors or unknown/unrecognised.

      We can handle SLB errors by flushing and reloading the SLB. We can
      handle TLB and ERAT multihit errors by flushing the TLB. (It appears
      we may not handle TLB and ERAT parity errors: I will investigate
      further and send a followup patch if appropriate.)

      This leaves us with uncorrectable errors. Uncorrectable errors are
      usually the result of ECC memory detecting an error that it cannot
      correct, but they also crop up in the context of PCI cards failing
      during DMA writes, and during CAPI error events.

      There are several types of UE, and there are 3 places a UE can occur:
      Skiboot, the kernel, and userspace. For Skiboot errors, we have the
      facility to make some recoverable. For userspace, we can simply kill
      (SIGBUS) the affected process. We have no meaningful way to deal with
      UEs in kernel space or in unrecoverable sections of Skiboot.

      Currently, these unrecovered UEs fall through to
      machine_check_expection() in traps.c, which calls die(), which OOPSes
      and sends SIGBUS to the process. This sometimes allows us to stumble
      onwards. For example we've seen UEs kill the kernel eehd and
      khugepaged. However, the process killed could have held a lock, or it
      could have been a more important process, etc: we can no longer make
      any assertions about the state of the machine. Similarly if we see a
      UE in skiboot (and again we've seen this happen), we're not in a
      position where we can make any assertions about the state of the
      machine.

      Likewise, for unknown or unrecognised errors, we're not able to say
      anything about the state of the machine.

      Therefore, if we have an unrecovered MCE, the most appropriate thing
      to do is to panic.

      The second reason is that since e784b6499d9c ("powerpc/powernv: Invoke
      opal_cec_reboot2() on unrecoverable machine check errors."), we
      attempt a special OPAL reboot on an unhandled MCE. This is so the
      hardware can record error data for later debugging.

      The comments in that commit assert that we are heading down the panic
      path anyway. At the moment this is not always true. With UEs in kernel
      space, for instance, they are marked as recoverable by the hardware,
      so if the attempt to reboot failed (e.g. old Skiboot), we wouldn't
      panic() but would simply die() and OOPS. It doesn't make sense to be
      staggering on if we've just tried to reboot: we should panic().

      Explicitly panic() on unrecovered MCEs on PowerNV.
      Update the comments appropriately.

      This fixes some hangs following EEH events on cxlflash setups.

      powerpc: Fix checkstop in native_hpte_clear() with lockdep

      native_hpte_clear() is called in real mode from two places:
      - Early in boot during htab initialisation if firmware assisted dump is
        active.
      - Late in the kexec path.

      In both contexts there is no need to disable interrupts are they are
      already disabled. Furthermore, locking around the tlbie() is only required
      for pre POWER5 hardware.

      On POWER5 or newer hardware concurrent tlbie()s work as expected and on 
pre
      POWER5 hardware concurrent tlbie()s could result in deadlock. This code
      would only be executed at crashdump time, during which all bets are off,
      concurrent tlbie()s are unlikely and taking locks is unsafe therefore the
      best course of action is to simply do nothing. Concurrent tlbie()s are not
      possible in the first case as secondary CPUs have not come up yet.

      nbd: Add locking for tasks

      The timeout handling introduced in
        7e2893a16d3e (nbd: Fix timeout detection)
      introduces a race condition which may lead to killing of tasks that are
      not in nbd context anymore. This was not observed or reproducable yet.

      This patch adds locking to critical use of task_recv and task_send to
      avoid killing tasks that already left the NBD thread functions. This
      lock is only acquired if a timeout occures or the nbd device
      starts/stops.

      The Atmel sdhci device needs a new quirk. sdhci_set_clock set the Clock
      Control Register to 0 before computing the new value and writing it.
      It disables the internal clock which causes a reset mecanism. If we
      write the new value before this reset mecanism is done, it will prevent
      the stabilisation of the internal clock, so a delay is needed. This
      delay is about 2-3 cycles of the base clock. To be safe, a 1 ms delay is
      used.

      arm64: Mark kernel page ranges contiguous

      With 64k pages, the next larger segment size is 512M. The linux
      kernel also uses different protection flags to cover its code and data.
      Because of this requirement, the vast majority of the kernel code and
      data structures end up being mapped with 64k pages instead of the larger
      pages common with a 4k page kernel.

      Recent ARM processors support a contiguous bit in the
      page tables which allows the a TLB to cover a range larger than a
      single PTE if that range is mapped into physically contiguous
      ram.

      So, for the kernel its a good idea to set this flag. Some basic
      micro benchmarks show it can significantly reduce the number of
      L1 dTLB refills.

      Add boot option to enable/disable CONT marking, as well as fix a
      bug found by Steve Capper.

      bpf: split state from prandom_u32() and consolidate {c, e}BPF prngs

      While recently arguing on a seccomp discussion that raw prandom_u32()
      access shouldn't be exposed to unpriviledged user space, I forgot the
      fact that SKF_AD_RANDOM extension actually already does it for some time
      in cBPF via commit 4cd3675ebf74 ("filter: added BPF random opcode").

      Since prandom_u32() is being used in a lot of critical networking code,
      lets be more conservative and split their states. Furthermore, consolidate
      eBPF and cBPF prandom handlers to use the new internal PRNG. For eBPF,
      bpf_get_prandom_u32() was only accessible for priviledged users, but
      should that change one day, we also don't want to leak raw sequences
      through things like eBPF maps.

      One thought was also to have own per bpf_prog states, but due to ABI
      reasons this is not easily possible, i.e. the program code currently
      cannot access bpf_prog itself, and copying the rnd_state to/from the
      stack scratch space whenever a program uses the prng seems not really
      worth the trouble and seems too hacky. If needed, taus113 could in such
      cases be implemented within eBPF using a map entry to keep the state
      space, or get_random_bytes() could become a second helper in cases where
      performance would not be critical.

      Both sides can trigger a one-time late init via prandom_init_once() on
      the shared state. Performance-wise, there should even be a tiny gain
      as bpf_user_rnd_u32() saves one function call. The PRNG needs to live
      inside the BPF core since kernels could have a NET-less config as well.

      random32: add prandom_init_once helper for own rngs

      Add a prandom_init_once() facility that works on the rnd_state, so that
      users that are keeping their own state independent from prandom_u32() can
      initialize their taus113 per cpu states.

      The motivation here is similar to net_get_random_once(): initialize the
      state as late as possible in the hope that enough entropy has been
      collected for the seeding. prandom_init_once() makes use of the recently
      introduced prandom_seed_full_state() helper and is generic enough so that
      it could also be used on fast-paths due to the DO_ONCE().

      once: make helper generic for calling functions once

      Make the get_random_once() helper generic enough, so that functions
      in general would only be called once, where one user of this is then
      net_get_random_once().

      The only implementation specific call is to get_random_bytes(), all
      the rest of this *_once() facility would be duplicated among different
      subsystems otherwise. The new DO_ONCE() helper will be used by prandom()
      later on, but might also be useful for other scenarios/subsystems as
      well where a one-time initialization in often-called, possibly fast
      path code could occur.

      Arun Parameswaran says:

      ====================
      Add support for Broadcom's iProc MDIO and Cygnus Ethernet PHY

      This patchset adds support for the iProc MDIO interface and the
      Broadcom Cygnus SoC's internal Ethernet PHY.

      The internal Ethernet PHY(s) in the Cygnus SoC's are accessed
      via the MDIO interface found in most of the iProc based chips.

      The patch also consolidates the common API's used by the
      Broadcom phys to a common library. Existing Broadcom phy
      drivers have been modified to use the common library API's.

      This patch series is based on Linux v4.3-rc1 and is avaliable in:
      https://github.com/Broadcom/cygnus-linux/tree/cygnus-net-phy-mdio-v3

      The Ethernet driver for the iProc family will be submitted soon,
      as will the device tree configurations for the different iProc
      family SoCs.

      Changes from v2:
      - Modified drivers/net/phy/Kconfig to modify the BCM_CYGNUS_PHY
        driver to 'depends on MDIO_BCM_IPROC' instead of 'select'.
      - Added github branch to the cover letter

      Changes from v1:
      - Updated device tree documentation for the iProc MDIO driver
        based on Florian's feedback.
      - Moved the core register defines from the Cygnus PHY driver to
        'include/linux/brcmphy.h' based on Florian's feedback.
      - Created a new patch/commit to modify the bcm7xxx phy driver
        to use the new core register defines.
      - Modified the Kconfig entry for the Broadcom PHY library to
        'tristate' instead of 'bool'

      The PHYs are 1000M/100M/10M capable with support for 'EEE'
      and 'APD' (Auto Power Down).

      This driver supports the following Broadcom Cygnus SoCs:
       - BCM583XX (BCM58300, BCM58302, BCM58303, BCM58305)
       - BCM113XX (BCM11300, BCM11320, BCM11350, BCM11360)

      The PHY's on these SoC's require some workarounds for
      stable operation, both during configuration time and
      during suspend/resume. This driver handles the
      application of the workarounds.

      RDS: connection scalability and performance improvements

      [v4]
      Re-sending the same patches from v3 again since my repost of
      patch 05/14 from v3 was whitespace damaged.

      [v3]
      Updated patch "[PATCH v2 05/14] RDS: defer the over_batch work to
      send worker" as per David Miller's comment [4] to avoid the magic
      value usage. Patch now makes use of already available but unused
      send_batch_count module parameter. Rest of the patches are same as
      earlier version v2 [3]

      [v2]:
      Dropped "[PATCH 05/15] RDS: increase size of hash-table to 8K" from
      earlier version [1]. I plan to address the hash table scalability using
      re-sizable hash tables as suggested by David Laight and David Miller [2]

      This series addresses RDS connection bottlenecks on massive workloads and
      improve the RDMA performance almost by 3X. RDS TCP also gets a small gain
      of about 12%.

      RDS is being used in massive systems with high scalability where several
      hundred thousand end points and tens of thousands of local processes
      are operating in tens of thousand sockets. Being RC(reliable connection),
      socket bind and release happens very often and any inefficiencies in
      bind hash look ups hurts the overall system performance. RDS bin 
hash-table
      uses global spin-lock which is the biggest bottleneck. To make matter 
worst,
      it uses rcu inside global lock for hash buckets.
      This is being addressed by simply using per bucket rw lock which makes the
      locking simple and very efficient. The hash table size is still an issue 
and
      I plan to address it by using re-sizable hash tables as suggested on the 
list.

      For RDS RDMA improvement, the completion handling is revamped so that we
      can do batch completions. Both send and receive completion handlers are
      split logically to achieve the same. RDS 8K messages being one of the
      key usecase, mr pool is adapted to have the 8K mrs along with default 1M
      mrs. And while doing this, few fixes and couple of bottlenecks seen with
      rds_sendmsg() are addressed.

      Series applies against 4.3-rc1 as well net-next. Its tested on Oracle
      hardware with IB fabric for both bcopy as well as RDMA mode. RDS TCP is
      tested with iXGB NIC. Like last time, iWARP transport is untested with
      these changes. The patchset is also available at below git repo:

      git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux.git 
net/rds/4.3-v3

      As a side note, the IB HCA driver I used for testing misses at least 3
      important patches in upstream to see the full blown IB performance and
      am hoping to get that in mainline with help of them.

      Merge branch 'pass_net_through_output_path'

      Eric W. Biederman says:

      ====================
      net: Pass net through the output path v2

      This is the next installment of my work to pass struct net through the
      output path so the code does not need to guess how to figure out which
      network namespace it is in, and ultimately routes can have output
      devices in another network namespace.

      The first patch in this series is a fix for a bug that came in when sk
      was passed through the functions in the output path, and as such is
      probably a candidate for net.  At the same time my later patches depend
      on it so sending the fix separately would be confusing.

      The second patch in this series is another fix that for an issue that
      came in when sk was passed through the output path.  I don't think it
      needs a backport as I don't think anyone uses the path where the code
      was incorrect.

      The rest of the patchset focuses on the path from xxx_local_out to
      dst_output and in the end succeeds in passing sock_net(sk) from the
      socket a packet locally originates on to the dst->output function.

      Given the size reduction in the code I think this counts as a cleanup as
      much as feature work.

      There remain a number of helper functions (like ip option processing) to
      take care of before the network stack can support destination devices in
      other network namespaces but with this set of changes the backbone of
      the work is done.

      ipv4: Fix ip_queue_xmit to pass sk into ip_local_out_sk

      After a packet has been encapsulated by a tunnel we should use the
      tunnel sockets local multicast loopback flag to control if the
      encapsulated packet should be locally loopback back.

      Pass sk into ip_local_out_sk so that in the rare case we are dealing
      with a tunneled packet whose tunnel destination address is a multicast
      address the kernel properly decides to loopback this packet.

      In practice I don't think this matters as ip_queue_xmit is used by
      tcp, l2tp and sctp none of which I am aware of uses ip level
      multicasting as they are all point to point communications protocols.
      Let's fix this before someone uses ip_queue_xmit for a tunnel protocol
      that does use multicast.

      In the rare case where sk != skb->sk ip_local_out_sk arranges

      This is a bug.

      Fix this bug by passing the sk parameter of ip_local_out_sk through

      Intel Wired LAN Driver Updates 2015-10-07

      This series contains updates to i40e and i40evf only.

      Paul updates i40e to simply increase the amount of time we wait for a
      reset to complete since we have seen in some rare occasions the reset
      can take longer to complete.

      Shannon updates the driver to turn on Wake-on-LAN by default if it is
      enabled in the hardware config to begin with, rather than always disable
      it and wait for the user to expressly turn it on.  Added new device id's
      and support for future devices.  Fixed a possible type compare problem
      between a size and possible negative number.  Also fixed a shift value
      that was wrong, which ended up with a bad bitmask.  Did general house
      cleaning of the driver to cleanup several low lying fruit in the
      driver.  Fixed an issue where new unicast address's would be added to
      the VSI list and then immediately removed and would never actually
      make it down to the hardware.  Resolved the issue by removing the
      separation from unicast and multicast in the search for filters to be
      deleted.

      Mitch fixes an issue where the hardware would continue to access the
      memory formerly used by the rings for a VF which have been removed,
      causing memory corruption or DMAR errors.  To relieve this condition,
      explicitly stop all rings associated with each VF before releasing its
      resources.  Also fixed a panic if the driver is unable to enable MSI-X
      or its unable to acquire enough vectors, so propagate interrupt
      allocation failure information to the calling function.  Cleaned up
      opcode that is not required.

      Carolyn extends the size of the test available for the interrupt names
      so that all the descriptive data available for the Flow Director
      interrupts is not truncated.

      Catherine fixes an issue where there was a possibility of speed getting
      set to 0 if advertised is set to 0 (which is the case when autoneg is
      disabled).

      Jesse fixes the checksum on big endian machines, so added code to swap
      it correctly.  Also fixed a bug in the return from get_link_status()
      where only true or false was being returned, but false could mean
      multiple things.  So allow the caller to get all the return values
      in the call chain bubbled back to the source so that the reason for
      the failure does not get lost.

      Anjali adds statistics to keep track of how many times we ask the stack
      to linearize the SKB because the hardware cannot handle SKBs with more
      than 8 frags per segment/single packet.

      mmc: host: omap_hsmmc: Fix MMC for omap3 legacy booting

      Starting with commit 7d607f917008 ("mmc: host: omap_hsmmc: use
      devm_regulator_get_optional() for vmmc") MMC on omap3 stopped working
      for legacy booting.

      This is because legacy booting sets up some of the resource in the
      platform init code, and for optional regulators always seem to
      return -EPROBE_DEFER for the legacy booting.

      Let's fix the issue by checking for device tree based booting for
      now. Then when omap3 boots in device tree only mode, this patch
      can be just reverted.

      Bluetooth: Send index information updates to monitor channel

      The Bluetooth public device address might change during controller setup
      and it makes it a lot simpler for monitoring tools if they just get told
      what the new address is. In addition include the manufacturer / company
      information of the controller. That allows for easy vendor specific HCI
      command and event handling.

      rcu: Better hotplug handling for synchronize_sched_expedited()

      Earlier versions of synchronize_sched_expedited() can prematurely end
      grace periods due to the fact that a CPU marked as cpu_is_offline()
      can still be using RCU read-side critical sections during the time that
      CPU makes its last pass through the scheduler and into the idle loop
      and during the time that a given CPU is in the process of coming online.
      This commit therefore eliminates this window by adding additional
      interaction with the CPU-hotplug operations.

      This commit makes the RCU CPU stall warning message print online/offline
      indications immediately after the CPU number.  A "O" indicates global
      offline, a "." global online, and a "o" indicates RCU believes that the
      CPU is offline for the current grace period and "." otherwise, and an
      "N" indicates that RCU believes that the CPU will be offline for the
      next grace period, and "." otherwise, all right after the CPU number.
      So for CPU 10, you would normally see "10-...:" indicating that everything
      believes that the CPU is online.

      i40e/i40evf: fix unicast mac address add

      When using something like "ip maddr add ..." to add another unicast mac
      address to the netdev, the mac address comes into the set_rx_mode handler
      in the multicast list whether it is a unicast or multicast address.
      This was confusing the code when it was trying to search for addresses
      that needed to be deleted from the VSI, because it was looking for the
      VSI unicast address in the netdev unicast list.  The result was that a
      new unicast address would get added to the VSI list and then immediately
      removed, and would never actually make it down into the hardware.

      This patch removes the separation from unicast and multicast in the search
      for filters to be deleted.  It also simplifies the logic a little with a
      jump to the bottom of the loop when an address is found.  Now it doesn't
      matter which netdev list the address is hiding in, we'll check them all.

      i40e: fix bug in return from get_link_status and avoid spurious link 
messages

      Previously, the driver could call this function and have only true/false
      returned, but false could mean multiple things like failure to read
      or link was down. This change allows the caller to get all return values
      in the call chain bubbled back to the source, which keeps information 
about
      failures from being lost.

      Also, in some unlikely scenarios, the firmware can become slow to respond
      to admin queue (AQ) queries for link state.  Should the AQ time out,
      the driver can detect the state and avoid a link change when there
      may have been none.

      i40e: make i40e_init_pf_fcoe to void

      i40e_init_pf_fcoe() didn't return anything except 0, it prints enough
      error info already, and no driver logic depends on the return value,
      so this can be void.

      i40e: stop VF rings

      Explicitly stop the rings belonging to each VF when disabling SR-IOV.
      Even though the VFs were gone, and the associated VSIs were removed, the
      rings were not stopped, and in some circumstances the hardware would
      continue to access the memory formerly used by the rings, causing memory
      corruption or DMAR errors, both of which would lead to general malaise
      of the kernel.

      To relieve this condition, explicitly stop all the rings associated with
      each VF before releasing its resources.

      The driver was disabling Wake-on-LAN by default and waiting for the user

      the start if enabled in the hardware config, which matches the behavior

      swiotlb: Enable it under x86 PAE

      Most distributions end up enabling SWIOTLB already with 32-bit
      kernels due to the combination of CONFIG_HYPERVISOR_GUEST|CONFIG_XEN=y
      as those end up requiring the SWIOTLB.

      However for those that are not interested in virtualization and
      run in 32-bit they will discover that: "32-bit PAE 4.2.0 kernel
      (no IOMMU code) would hang when writing to my USB disk. The kernel
      spews million(-ish messages per sec) to syslog, effectively
      "hanging" userspace with my kernel.

      Oct  2 14:33:06 voodoochild kernel: [  223.287447] nommu_map_sg:
      overflow 25dcac000+1024 of device mask ffffffff

      overflow 25dcac000+1024 of device mask ffffffff
      ... etc ..."

      Enabling it makes the problem go away.

      N.B. With a6dfa128ce5c414ab46b1d690f7a1b8decb8526d
      "config: Enable NEED_DMA_MAP_STATE by default when SWIOTLB is selected"
      we also have the important part of the SG macros enabled to make this
      work properly - in case anybody wants to backport this patch.

      drm/amdgpu: fix 32-bit compiler warning

      The new amdgpu driver passes a user space pointer in a 64-bit structure
      member, which is the correct way to do it, but it attempts to
      directly cast it to a __user pointer in the kernel, which causes
      a warning in three places:

      drm/amd/amdgpu/amdgpu_cs.c: In function 'amdgpu_cs_parser_init':
      drm/amd/amdgpu/amdgpu_cs.c:180:21: warning: cast to pointer from integer 
of different size [-Wint-to-pointer-cast]
        chunk_array_user = (uint64_t __user *)(cs->in.chunks);

      This changes all three to add an intermediate cast to 'unsigned long'
      as other drivers do. This avoids the warning and works correctly on
      both 32-bit and 64-bit architectures.

      perf tools: Fix build break on powerpc due to sample_reg_masks

      perf_regs.c does not get built on Powerpc as CONFIG_PERF_REGS is false.
      So the weak definition for 'sample_regs_masks' doesn't get picked up.

      Adding perf_regs.o to util/Build unconditionally, exposes a redefinition
      error for 'perf_reg_value()' function (due to the static inline version

      arm64: hw_breakpoint: use target state to determine ABI behaviour

      The arm64 hw_breakpoint interface is slightly less flexible than its
      32-bit counterpart, thanks to some changes in the architecture rendering
      unaligned watchpoint addresses obselete for AArch64.

      However, in a multi-arch environment (i.e. debugging a 32-bit target
      with a 64-bit GDB under a 64-bit kernel), we need to provide a feature
      compatible interface to GDB in order for debugging to function correctly.

      This patch adds a new helper, is_compat_bp,  to our hw_breakpoint
      implementation which changes the interface behaviour based on the
      architecture of the debug target as opposed to the debugger itself.
      This allows debugged to function as expected for multi-arch
      configurations without relying on deprecated architectural behaviours
      when debugging native applications.

      OVS conntrack fixes for net

      The userspace side of the Open vSwitch conntrack changes is currently
      undergoing review, which has highlighted some minor bugs in the existing
      conntrack implementation in the kernel, as well as pointing out some
      future-proofing that can be done on the interface to reduce the need for
      additional compatibility code in future.

      The biggest changes here are to the userspace API for the ct_state match
      field and the CT action. This series proposes to firstly extend the 
ct_state
      match field to 32 bits, ensuring to reject any currently unsupported bits.
      Secondly, rather than representing CT action flags within a 32-bit field,
      simply use a netlink attribute as presence of the single flag that is
      defined today. This also serves to reject unsupported ct action flag bits.

      v4: Use 12-character abbreviated hashes in commit messages.
      v3: Fully acked.
      v2: Address minor style feedback, add acks.
      v1: Initial post.

      openvswitch: Change CT_ATTR_FLAGS to CT_ATTR_COMMIT

      Previously, the CT_ATTR_FLAGS attribute, when nested under the
      OVS_ACTION_ATTR_CT, encoded a 32-bit bitmask of flags that modify the
      semantics of the ct action. It's more extensible to just represent each
      flag as a nested attribute, and this requires no additional error
      checking to reject flags that aren't currently supported.

      openvswitch: Extend ct_state match field to 32 bits

      The ct_state field was initially added as an 8-bit field, however six of
      the bits are already being used and use cases are already starting to
      appear that may push the limits of this field. This patch extends the
      field to 32 bits while retaining the internal representation of 8 bits.
      This should cover forward compatibility of the ABI for the foreseeable
      future.

      This patch also reorders the OVS_CS_F_* bits to be sequential.

      openvswitch: Reject ct_state unsupported bits

      Previously, if userspace specified ct_state bits in the flow key which
      are currently undefined (and therefore unsupported), then they would be
      ignored. This could cause unexpected behaviour in future if userspace is
      extended to support additional bits but attempts to communicate with the
      current version of the kernel. This patch rectifies the situation by
      rejecting such ct_state bits.

      s390/qeth: optimize MAC handling in rx_mode callback

      In layer2 mode of the qeth driver, MAC address lists
      from struct net_device require mapping to the OSA-card.
      The existing implementation is inefficient for lists with
      more than several MAC addresses, since for every
      ndo_set_rx_mode callback it removes all MAC addresses first,
      and then registers the current MAC address list.
      This patch changes implementation of ndo_set_rx_mode callback
      in qeth, only performing hardware registration/removal for
      new/deleted addresses. To shorten lookup of MAC addresses
      registered addresses are kept in a hashtable instead of a

      net: Lookup actual route when oif is VRF device

      If the user specifies a VRF device in a get route query the custom route
      pointing to the VRF device is returned:

          $ ip route ls table vrf-red
          unreachable default

      First 2 patches are re-sends of patches that got lost in the ethosphere
      Tuesday; they were part of the first round of l3mdev conversions.
      Next 3 handle the source address lookup for raw and datagram sockets
      bound to a VRF device.

      The conversion to the get_saddr op also fixes locally originated TCP
      packets showing up at the VRF device. The use of the FLOWI_FLAG_L3MDEV_SRC
      flag in ip_route_connect_init was causing locally generated packets
      to skip the VRF device.

      gianfar: Add WAKE_UCAST and "wake-on-filer" support

      This enables eTSEC's filer (Rx parser) and the FGPI Rx
      interrupt (Filer General Purpose Interrupt) as a wakeup
      source event.

      Upon entering suspend state, the eTSEC filer is given
      a rule to match incoming L2 unicast packets.  A packet
      matching the rule will be enqueued in the Rx ring and
      a FGPI Rx interrupt will be asserted by the filer to
      wakeup the system.  Other packet types will be dropped.
      On resume the filer table is restored to the content
      before entering suspend state.
      The set of rules from gfar_filer_config_wol() could be
      extended to implement other WoL capabilities as well.

      The "fsl,wake-on-filer" DT binding enables this capability
      on certain platforms that feature the necessary power
      management infrastructure, targeting mainly printing and
      imaging applications.

      update_mmu_cache() consists of a dsb(ishst) instruction so that new user
      mappings are guaranteed to be visible to the page table walker on

      In reality this can be a very expensive operation which is rarely needed.
      Removing this barrier shows a modest improvement in hackbench scores and
      , in the worst case, we re-take the user fault and establish that there

      arm64: switch_mm: simplify mm and CPU checks

      switch_mm performs some checks to try and avoid entering the ASID
      allocator:

        (1) If we're switching to the init_mm (no user mappings), then simply
            set a reserved TTBR0 value with no page table (the zero page)

        (2) If prev == next *and* the mm_cpumask indicates that we've run on
            this CPU before, then we can skip the allocator.

      However, there is plenty of redundancy here. With the new ASID allocator,
      if prev == next, then we know that our ASID is valid and do not need to
      worry about re-allocation. Consequently, we can drop the mm_cpumask check
      in (2) and move the prev == next check before the init_mm check, since
      if prev == next == init_mm then there's nothing to do.

      arm64: tlbflush: avoid flushing when fullmm == 1

      The TLB gather code sets fullmm=1 when tearing down the entire address
      space for an mm_struct on exit or execve. Given that the ASID allocator
      will never re-allocate a dirty ASID, this flushing is not needed and can
      simply be avoided in the flushing code.

      arm64: tlbflush: remove redundant ASID casts to (unsigned long)

      The ASID macro returns a 64-bit (long long) value, so there is no need
      to cast to (unsigned long) before shifting prior to a TLBI operation.

      arm64: mm: rewrite ASID allocator and MM context-switching code

      Our current switch_mm implementation suffers from a number of problems:

        (1) The ASID allocator relies on IPIs to synchronise the CPUs on a
            rollover event

        (2) Because of (1), we cannot allocate ASIDs with interrupts disabled
            and therefore make use of a TIF_SWITCH_MM flag to postpone the
            actual switch to finish_arch_post_lock_switch

        (3) We run context switch with a reserved (invalid) TTBR0 value, even
            though the ASID and pgd are updated atomically

        (4) We take a global spinlock (cpu_asid_lock) during context-switch

        (5) We use h/w broadcast TLB operations when they are not required
            (e.g. in flush_context)

      This patch addresses these problems by rewriting the ASID algorithm to
      match the bitmap-based arch/arm/ implementation more closely. This in
      turn allows us to remove much of the complications surrounding switch_mm,
      including the ugly thread flag.

      arm64: flush: use local TLB and I-cache invalidation

      There are a number of places where a single CPU is running with a
      private page-table and we need to perform maintenance on the TLB and
      I-cache in order to ensure correctness, but do not require the operation
      to be broadcast to other CPUs.

      This patch adds local variants of tlb_flush_all and __flush_icache_all
      to support these use-cases and updates the callers respectively.
      __local_flush_icache_all also implies an isb, since it is intended to be
      used synchronously.

      When cold-booting a CPU, we must invalidate any junk entries from the
      local TLB prior to enabling the MMU. This doesn't require broadcasting
      within the inner-shareable domain, so de-scope the operation to apply

      Intel Wired LAN Driver Updates 2015-10-03

      This series contains updates to i40e and i40evf, some of which are to
      resolve more Red Hat bugzilla issues.

      Jiang Liu updates the i40e and i40evf drivers to use numa_mem_id()
      instead of numa_node_id() to get the nearest node with memory which
      better supports memoryless nodes.

      Anjali fixes an issue from Dan Carpenter <dan.carpenter@xxxxxxxxxx>,
      to resolve a memory leak in X722 RSS configuration path, where we should
      free the memory allocated before exiting.

      Shannon modifies the drivers to ensure we have the spinlocks before we
      clear the ARQ and ASQ management registers.  In addition, we widen the
      locked portion insert a sanity check to ensure we are working with safe
      register values.

      Mitch fixes an issue where under certain circumstances, we can get an
      extra VF_RESOURCES message from the PF driver at runtime.  When this
      occurs, we need to parse it because our VSI may have changed and that
      will affect the relationship with the PF driver.  But this parsing also
      blows away our current MAC address, so resolve the issue by restoring
      the current MAC address from the netdev struct after we parse the
      resource message.

      I tested the test by incorrectly annotating __kernel_vsyscall,

      x86/uaccess: Tell the compiler that uaccess is unlikely to fault

      GCC doesn't realize that get_user(), put_user(), and their __
      variants are unlikely to fail.  Tell it.

      I noticed this while playing with the C entry code.

       Before:
             text     data      bss       dec    filename
         21828763  5194760  1277952  28301475    vmlinux.baseline

       After:
            text      data      bss       dec    filename
         21828379  5194760  1277952  28301091    vmlinux.new

      The generated code shrunk by 384 bytes.

       "This patch series fixes up a couple of architecture issues where
        strscpy wasn't configured correctly (missing on h8300, duplicating
        local and asm-generic copies on powerpc and tile).

        It also adds a use of zero_bytemask() to the final store for strscpy
        to avoid writing uninitialized data to the destination.  However, to
        make this work we had to add support for zero_bytemask() to the two
        architectures that didn't have it (alpha and tile), because they were
        providing their own local copies, but didn't provide the
        zero_bytemask() that was previously only required when building with
        CONFIG_DCACHE_WORD_ACCESS"

      [ Side note: there is still no actual users of strscpy except for the
        one preexisting use in arch/tile that predates the generic version.
        So this is all about fixing the infrastructure so that we eventually
        can start using it.  - Linus ]

      Revert "fs: do not prefault sys_write() user buffer pages"

      This reverts commit 998ef75ddb5709bbea0bf1506cd2717348a3c647.

      The commit itself does not appear to be buggy per se, but it is exposing
      a bug in ext4 (and Ted thinks ext3 too, but we solved that by getting
      rid of it).  It's too late in the release cycle to really worry about
      this, even if Dave Hansen has a patch that may actually fix the
      underlying ext4 problem.  We can (and should) revisit this for the next
      release.

      The problem is that moving the prefaulting later now exposes a special
      case with partially successful writes that isn't handled correctly.  And
      the prefaulting likely isn't normally even that much of a performance
      issue - it looks like at least one reason Dave saw this in his
      performance tests is that he also ran them on Skylake that now supports
      the new SMAP code, which makes the normally very cheap user space
      prefaulting noticeably more expensive.

      cxl: Fix number of allocated pages in SPA

      The scheduled process area is currently allocated before assigning the
      correct maximum processes to the AFU, which will mean we only ever
      allocate a fixed number of pages for the scheduled process area. This
      will limit us to 958 processes with 2 x 64K pages. If we try to use more
      processes than that we'd probably overrun the buffer and corrupt memory
      or crash.

      AFUs that require three or more interrupts per process will not be
      affected as they are already limited to less processes than that, but we
      could hit it on an AFU that requires 0, 1 or 2 interrupts per process,
      or when using 4K pages.

      This patch moves the initialisation of the num_procs to before the SPA
      allocation so that enough pages will be allocated for the number of
      processes that the AFU supports.

      drm/qxl: avoid dependency lock

      locks dev->struct_mutex. However this lock could be already
      locked if the call came from qxl_gem_object_free.

      to call them and the possible deadlock.

      drm/qxl: avoid buffer reservation in qxl_crtc_page_flip

      This avoid a dependency lock error.
      According to https://lwn.net/Articles/548909/ users of WW mutex API
      should avoid using different context.
      When a buffer is reserved with qxl_bo_reserve a ww_mutex_lock without
      context is used. However during qxl_draw_dirty_fb different locks
      with specific context are used.
      This is detected during a machine booting with a debug kernel with lock
      dependency checking enabled.
      Like many other function in this file to avoid this problem object
      pinning is used. Once the object is pinned is not necessary to keep
      the lock so it can be released avoiding the locking problem.

      Bluetooth: btbcm: Read the local name in setup stage

      The Broadcom Bluetooth controllers have the chip name included in the

      read the local name and print it out. This is only done during setup
      stage and only once before loading the firmware and once after loading
      the firmware.

      For the Broadcom based controllers from Apple, the name is only read once
      after determining the chip id.

      Input: ads7846 - correct the value got from SPI

      According to the touch controller spec, SPI return a 16 bit value, only 12
      bits are valid, they are bit[14-3].

      The value of MISO and MOSI can be configured when SPI is in idle mode.
      Currently this touch driver assumes the SPI bus sets the MOSI and MISO in
      low level when SPI bus is in idle mode. So the bit[15] of the value got
      from SPI bus is always 0. But when SPI bus congfigures the MOSI and MISO 
in
      high level during the SPI idle mode, the bit[15] of the value get from SPI
      is always 1. If bit[15] is not masked, we may get the wrong value.

      Mask the invalid bit to make sure the correct value gets returned.
      Regardless of the SPI bus idle configuration.

      1. Rename __rcu_sync_is_idle() to rcu_sync_lockdep_assert() and
         change it to use rcu_lockdep_assert().

      2. Change rcu_sync_is_idle() to return rsp->gp_state == GP_IDLE
         unconditonally, this way we can remove the same check from
         rcu_sync_lockdep_assert() and clearly isolate the debugging

      Note: rcu_sync_enter()->wait_event(gp_state == GP_PASSED) needs
      another CONFIG_PROVE_RCU check, the same as is done in ->sync(); but
      this needs some simple preparations in the core RCU code to avoid the

      locking/percpu-rwsem: Make use of the rcu_sync infrastructure

      Currently down_write/up_write calls synchronize_sched_expedited()

      This avoids the _expedited "big hammer", and this can be faster in
      the contended case or even in the case when a single thread does
      down_write/up_write in a loop.

      Of course, a single down_write() will take more time, but otoh it
      will be much more friendly to the whole system.

      To simplify the review this patch doesn't update the comments, fixed
      by the next change.

      IB/cma: Accept connection without a valid netdev on RoCE

      The netdev checks recently added to RDMA CM expect a valid netdev to be
      found for both InfiniBand and RoCE, but the code that find a netdev is
      only implemented for InfiniBand.

      Currently RoCE doesn't provide an API to find the netdev matching a

enforcement
      for each incoming connections when the link layer is RoCE.

      in kernels built with CONFIG_PROVE_RCU=y.

      rcu: Create rcu_sync infrastructure

      The rcu_sync infrastructure can be thought of as infrastructure to be
      used to implement reader-writer primitives having extremely lightweight
      readers during times when there are no writers.  The first use is in
      the percpu_rwsem used by the VFS subsystem.

      This infrastructure is functionally equivalent to

              struct rcu_sync_struct {
                      atomic_t counter;
              };

        /* Check possibility of fast-path read-side operations. */
              static inline bool rcu_sync_is_idle(struct rcu_sync_struct *rss)
              {
                      return atomic_read(&rss->counter) == 0;
              }

        /* Tell readers to use slowpaths. */
              static inline void rcu_sync_enter(struct rcu_sync_struct *rss)
              {
                      atomic_inc(&rss->counter);
                      synchronize_sched();
              }

        /* Allow readers to once again use fastpaths. */
              static inline void rcu_sync_exit(struct rcu_sync_struct *rss)
              {
                      synchronize_sched();
                      atomic_dec(&rss->counter);
              }

      The main difference is that it records the state and only calls
      synchronize_sched() if required.  At least some of the calls to
      synchronize_sched() will be optimized away when rcu_sync_enter() and
      rcu_sync_exit() are invoked repeatedly in quick succession.

      locktorture: Support rtmutex torturing

      Real time mutexes is one of the few general primitives
      that we do not have in locktorture. Address this -- a few
      considerations:

      o To spice things up, enable competing thread(s) to become
      rt, such that we can stress different prio boosting paths
      in the rtmutex code. Introduce a ->task_boost callback,
      only used by rtmutex-torturer. Tasks will boost/deboost
      around every 50k (arbitrarily) lock/unlock operations.

      o Hold times are similar to what we have for other locks:
      only occasionally having longer hold times (per ~200k ops).

      xprtrdma: Don't require LOCAL_DMA_LKEY support for fastreg

      There is no need to require LOCAL_DMA_LKEY support as the
      PD allocation makes sure that there is a local_dma_lkey. Also
      correctly set a return value in error path.

      This caused a NULL pointer dereference in mlx5 which removed
      the support for LOCAL_DMA_LKEY.

      documentation: Correct doc to use rcu_dereference_protected

      As there is lots of misinformation and outdated information on the
      Internet about nearly all topics related to the kernel, I thought it
      would be best if I based my RCU code on the guidelines of the examples
      in the Documentation/ tree of the latest kernel. One thing that stuck
      out when reading the whatisRCU.txt document was, "interesting how we
      don't need any function to dereference rcu protected pointers when doing
      updates if a lock is held. I wonder how static analyzers will work with
      that." Then, a few weeks later, upon discovering sparse's __rcu support,
      I ran it over my code, and lo and behold, things weren't done right.
      Examining other RCU usages in the kernel reveal consistent usage of
      rcu_dereference_protected, passing in lockdep_is_held as the
      conditional. So, this patch adds that idiom to the documentation, so
      that others ahead of me won't endure the same exercise.

      Documentation/memory-barriers.txt calls out RCU as one of the sets
      of primitives associated with ACQUIRE and RELEASE.  There really
      is an association in that rcu_assign_pointer() includes a RELEASE

      rcu_read_unlock() have ACQUIRE and RELEASE semantics, which they do not.

      Unfortunately, the compiler is within its rights to (for example) use
      byte-at-a-time writes to update the pointer, which would fatally confuse
      concurrent readers.  This patch therefore adds the needed WRITE_ONCE()

      rculist: Make list_entry_rcu() use lockless_dereference()

      The current list_entry_rcu() implementation copies the pointer to a stack
      variable, then invokes rcu_dereference_raw() on it.  This results in an
      additional store-load pair.  Now, most compilers will emit normal store
      and load instructions, which might seem to be of negligible overhead,
      but this results in a load-hit-store situation that can cause surprisingly
      long pipeline stalls, even on modern microprocessors.  The problem is
      that it takes time for the store to get the store buffer updated, which
      can delay the subsequent load, which immediately follows.

      This commit therefore switches to the lockless_dereference() primitive,
      which does not expect the __rcu annotations (that are anyway not present
      in the list_head structure) and which, like rcu_dereference_raw(),
      does not check for an enclosing RCU read-side critical section.
      Most importantly, it does not copy the pointer, thus avoiding the
      load-hit-store overhead.

      This commit loosens rcutree.rcu_fanout_leaf range checks

      This fallback is accompanied by a WARN_ON(), and both occur when the

      CPUs.  For example, given the current four-level limit for the rcu_node
      tree, a system with more than 16 CPUs built with CONFIG_FANOUT=2 must
      have rcutree.rcu_fanout_leaf larger than 2.

      rcu: Don't disable preemption for Tiny and Tree RCU readers

      Because preempt_disable() maps to barrier() for non-debug builds,
      it forces the compiler to spill and reload registers.  Because Tree
      RCU and Tiny RCU now only appear in CONFIG_PREEMPT=n builds, these
      barrier() instances generate needless extra code for each instance of
      rcu_read_lock() and rcu_read_unlock().  This extra code slows down Tree
      RCU and bloats Tiny RCU.

      This commit therefore removes the preempt_disable() and preempt_enable()
      from the non-preemptible implementations of __rcu_read_lock() and
      __rcu_read_unlock(), respectively.  However, for debug purposes,
      preempt_disable() and preempt_enable() are still invoked if
      CONFIG_PREEMPT_COUNT=y, because this allows detection of sleeping inside
      atomic sections in non-preemptible kernels.

      However, Tiny and Tree RCU operates by coalescing all RCU read-side
      critical sections on a given CPU that lie between successive quiescent
      states.  It is therefore necessary to compensate for removing barriers
      from __rcu_read_lock() and __rcu_read_unlock() by adding them to a
      couple of the RCU functions invoked during quiescent states, namely to
      rcu_all_qs() and rcu_note_context_switch().  However, note that the latter
      is more paranoia than necessity, at least until link-time optimizations
      become more aggressive.

      This is based on an earlier patch by Paul E. McKenney, fixing
      a bug encountered in kernels built with CONFIG_PREEMPT=n and
      CONFIG_PREEMPT_COUNT=y.

      they use sched_setscheduler_nocheck().  However, this is not exported to
      modules, which results in the following error when building locktorture
      as a module:

      ERROR: "sched_setscheduler_nocheck" [kernel/locking/locktorture.ko] 
undefined!

      This commit therefore adds an EXPORT_SYMBOL_GPL() to allow this function
      to be invoked from locktorture when built as a module.

      usnic: add missing clauses to BSD license

      The usnic_verbs kernel module was clearly marked with the following in
      its code:

        MODULE_LICENSE("Dual BSD/GPL");

      However, we accidentally left a few clauses of the BSD text out of the
      license header in all the source files.  This commit fixes that: all

      arm64: Don't relocate non-existent initrd

      When booting a kernel without an initrd, the kernel reports that it
      moves -1 bytes worth, having gone through the motions with initrd_start
      equal to initrd_end:

          Moving initrd from [4080000000-407fffffff] to [9fff49000-9fff48fff]

      Prevent this by bailing out early when the initrd size is zero (i.e. we
      have no initrd), avoiding the confusing message and other associated
      work.

      perf/x86/intel/uncore: Fix multi-segment problem of 
perf_event_intel_uncore

      In multi-segment system, uncore devices may belong to buses whose segment
      number is other than 0:

        ....
        0000:ff:10.5 System peripheral: Intel Corporation Xeon E5 v3/Core i7 
Scratchpad & Semaphore Registers (rev 03)
        ...
        0001:7f:10.5 System peripheral: Intel Corporation Xeon E5 v3/Core i7 
Scratchpad & Semaphore Registers (rev 03)
        ...
        0001:bf:10.5 System peripheral: Intel Corporation Xeon E5 v3/Core i7 
Scratchpad & Semaphore Registers (rev 03)
        ...
        0001:ff:10.5 System peripheral: Intel Corporation Xeon E5 v3/Core i7 
Scratchpad & Semaphore Registers (rev 03
        ...

      In that case, relation of bus number and physical id may be broken
      because "uncore_pcibus_to_physid" doesn't take account of PCI segment.
      For example, bus 0000:ff and 0001:ff uses the same entry of
      "uncore_pcibus_to_physid" array.

      This patch fixes this problem by introducing the segment-aware 
pci2phy_map instead.

      perf/x86: Add Intel cstate PMUs support

      This patch adds new PMUs to support cstate related free running
      (read-only) counters. These counters may be used simultaneously by other
      tools, such as turbostat. However, it still make sense to implement them
      in perf. Because we can conveniently collect them together with other
      events, and allow to use them from tools without special MSR access
      code.

      These counters include CORE_C*_RESIDENCY and PKG_C*_RESIDENCY.
      According to counters' scope and category, two PMUs are registered with
      the perf_event core subsystem.

       - 'cstate_core': The counter is available for each physical core. The
                        counters include CORE_C*_RESIDENCY.

       - 'cstate_pkg':  The counter is available for each physical package. The
                        counters include PKG_C*_RESIDENCY.

      The events are exposed in sysfs for use by perf stat and other tools.
      The files are:

        /sys/devices/cstate_core/events/c*-residency
        /sys/devices/cstate_pkg/events/c*-residency

      These events only support system-wide mode counting.
      The /sys/devices/cstate_*/cpumask file can be used by tools to figure
      out which CPUs to monitor by default.

      The PMU type (attr->type) is dynamically allocated and is available from
      /sys/devices/core_misc/type and /sys/device/cstate_*/type.

      Sampling is not supported.

      Here is an example.

       - To caculate the fraction of time when the core is running in C6 state
         CORE_C6_time% = CORE_C6_RESIDENCY / TSC

       # perf stat -x, -e"cstate_core/c6-residency/,msr/tsc/" -C0 -- taskset -c 
0 sleep 5

         11838820015,,cstate_core/c6-residency/,5175919658,100.00
         11877130740,,msr/tsc/,5175922010,100.00

       For sleep, 99.7% of time we ran in C6 state.

       # perf stat -x, -e"cstate_core/c6-residency/,msr/tsc/" -C0 -- taskset -c 
0 busyloop

         1253316,,cstate_core/c6-residency/,4360969154,100.00
         10012635248,,msr/tsc/,4360972366,100.00

       For busyloop, 0.01% of time we ran in C6 state.

      sched/core: Drop unlikely behind BUG_ON()

      (1) For !CONFIG_BUG cases, the bug call is a no-op, so we couldn't care
          less and the change is ok.

      (2) PPC and MIPS, which HAVE_ARCH_BUG_ON, do not rely on branch 
predictions
          as it seems to be pointless [1] and thus callers should not be trying 
to
          push an optimization in the first place.

      (3) For CONFIG_BUG and !HAVE_ARCH_BUG_ON cases, BUG_ON() contains an
          unlikely compiler flag already.

      Hence, we can drop unlikely behind BUG_ON().

      This alternative patch solves the problem by not calling
      sched_info_{de,}queued() in {de,en}queue_task(). Therefore the
      sched_info state is preserved and things work as expected.

      By inlining the {de,en}queue_task() functions the new condition
      becomes (mostly) a compile-time constant and we'll not emit any new
      branch instructions.

      It even shrinks the code (due to inlining {en,de}queue_task()):

      sched/numa: Fix task_tick_fair() from disabling numa_balancing

      If static branch 'sched_numa_balancing' is enabled, it should kickstart
      NUMA balancing through task_tick_numa(). However the following commit:

        2a595721a1fa ("sched/numa: Convert sched_numa_balancing to a 
static_branch")

      erroneously disables this.

      Fix this anomaly by enabling task_tick_numa() when the static branch
      'sched_numa_balancing' is enabled.

      sched/core: More notrace annotations

      preempt_schedule_common() is marked notrace, but it does not use
      _notrace() preempt_count functions and __schedule() is also not marked
      notrace, which means that its perfectly possible to end up in the
      tracer from preempt_schedule_common().

      Steve says:

        | Yep, there's some history to this. This was originally the issue that
        | caused function tracing to go into infinite recursion. But now we have
        | preempt_schedule_notrace(), which is used by the function tracer, and
        | that function must not be traced till preemption is disabled.
        |
        | Now if function tracing is running and we take an interrupt when
        | NEED_RESCHED is set, it calls
        |
        |   preempt_schedule_common() (not traced)
        |
        | But then that calls preempt_disable() (traced)
        |
        | function tracer calls preempt_disable_notrace() followed by
        | preempt_enable_notrace() which will see NEED_RESCHED set, and it will
        | call preempt_schedule_notrace(), which stops the recursion, but
        | still calls __schedule() here, and that means when we return, we call
        | the __schedule() from preempt_schedule_common().
        |
        | That said, I prefer this patch. Preemption is disabled before calling
        | __schedule(), and we get rid of a one round recursion with the
        | scheduler.

      sched/core: Robustify preemption leak checks

      When we warn about a preempt_count leak; reset the preempt_count to
      the known good value such that the problem does not ripple forward.

      This is most important on x86 which has a per cpu preempt_count that is
      not saved/restored (after this series). So if you schedule with an
      invalid (!2*PREEMPT_DISABLE_OFFSET) preempt_count the next task is
      messed up too.

      Enforcing this invariant limits the borkage to just the one task.

      sched/core: Create preempt_count invariant

      Assuming units of PREEMPT_DISABLE_OFFSET for preempt_count() numbers.

      Now that TASK_DEAD no longer results in preempt_count() == 3 during
      scheduling, we will always call context_switch() with preempt_count()
      == 2.

      However, we don't always end up with preempt_count() == 2 in
      finish_task_switch() because new tasks get created with
      preempt_count() == 1.

      Create FORK_PREEMPT_COUNT and set it to 2 and use that in the right
      places. Note that we cannot use INIT_PREEMPT_COUNT as that serves
      another purpose (boot).

      After this, preempt_count() is invariant across the context switch,
      with exception of PREEMPT_ACTIVE.

      sched/core: Rework TASK_DEAD preemption exception

      TASK_DEAD is special in that the final schedule call from do_exit()
      must be done with preemption disabled.

      This means we end up scheduling with a preempt_count() higher than
      usual (3 instead of the 'expected' 2).

      Since future patches will want to rely on an invariant
      preempt_count() value during schedule, fix this up.

      sched/core: Simplify INIT_PREEMPT_COUNT

      As per the following commit:

        d86ee4809d03 ("sched: optimize cond_resched()")

      we need PREEMPT_ACTIVE to avoid cond_resched() from working before
      the scheduler is set up.

      However, keeping preemption disabled should do the same thing
      already, making the PREEMPT_ACTIVE part entirely redundant.

      The only complication is !PREEMPT_COUNT kernels, where
      PREEMPT_DISABLED ends up being 0. Instead we use an unconditional
      PREEMPT_OFFSET to set preempt_count() even on !PREEMPT_COUNT
      kernels.

      sched/core: Fix TASK_DEAD race in finish_task_switch()

      So the problem this patch is trying to address is as follows:

              CPU0                            CPU1

              context_switch(A, B)
                                              ttwu(A)
                                                LOCK A->pi_lock
                                                A->on_cpu == 0
              finish_task_switch(A)
                prev_state = A->state  <-.
                WMB                      |
                A->on_cpu = 0;           |
                UNLOCK rq0->lock         |
                                         |    context_switch(C, A)
                                         `--  A->state = TASK_DEAD
                prev_state == TASK_DEAD
                  put_task_struct(A)
                                              context_switch(A, C)
                                              finish_task_switch(A)
                                                A->state == TASK_DEAD
                                                  put_task_struct(A)

      The argument being that the WMB will allow the load of A->state on CPU0
      to cross over and observe CPU1's store of A->state, which will then
      result in a double-drop and use-after-free.

      Now the comment states (and this was true once upon a long time ago)
      that we need to observe A->state while holding rq->lock because that
      will order us against the wakeup; however the wakeup will not in fact
      acquire (that) rq->lock; it takes A->pi_lock these days.

      We can obviously fix this by upgrading the WMB to an MB, but that is
      expensive, so we'd rather avoid that.

      The alternative this patch takes is: smp_store_release(&A->on_cpu, 0),
      which avoids the MB on some archs, but not important ones like ARM.

      dm: fix request-based dm error reporting

      end_clone_bio() is a endio callback for clone bio and should check
      and save the clone's bi_error for error reporting.  However,
      4246a0b63bd8 ("block: add a bi_error field to struct bio") changed
      the function to check the original bio's bi_error, which is 0.

      Without this fix, clone's error is ignored and reported to the
      original request as success.  Thus data corruption will be observed.

      BTRFS: support NFSv2 export

      The "fh_len" passed to ->fh_to_* is not guaranteed to be that same as
      that returned by encode_fh - it may be larger.

      With NFSv2, the filehandle is fixed length, so it may appear longer
      than expected and be zero-padded.

      So we must test that fh_len is at least some value, not exactly equal
      to it.

      x86/xen/p2m: hint at the last populated P2M entry

      With commit 633d6f17cd91ad5bf2370265946f716e42d388c6 (x86/xen: prepare
      p2m list for memory hotplug) the P2M may be sized to accomdate a much
      larger amount of memory than the domain currently has.

      When saving a domain, the toolstack must scan all the P2M looking for
      populated pages.  This results in a performance regression due to the
      unnecessary scanning.

      Instead of reporting (via shared_info) the maximum possible size of
      the P2M, hint at the last PFN which might be populated.  This hint is
      increased as new leaves are added to the P2M (in the expectation that
      they will be used for populated entries).

      ath10k is using Native WiFi mode as default mode for both of
      Tx and Rx path, but it could be changed when driver registers
      with a module parameter for specific purpose such as mesh.

      The Rx decap mode sent to firmware during WMI initialization should
      use the same mode that driver configured at its registration stage
      in case of using raw mode, so that host driver receives MAC frame
      header containing necessary fields such as QoS and Mesh Control
      and uses them in right way to make data traffic work.

      Neither myself or Liam is especially interested in this driver any more
      and the devices are already covered by the general ex-Wolfson entry so
      just remove this.

      ASoC: tas2552: fix dBscale-min declaration

      The minimum volume level for the TAS2552 (control register value 0x00)
      is -7dB however the driver declares it as -0.07dB.

      Running amixer before the patch reports:
      dBscale-min=-0.07dB,step=1.00dB,mute=0

      Running amixer with the patch applied reports:

      cxl: Workaround malformed pcie packets on some cards

      This works around a pcie host bridge defect on some cards, that can cause
      malformed Transaction Layer Packet (TLP) errors to be erroneously 
reported.

      The upper nibble of the vendor section PSL revision is used to distinguish
      between different cards. The affected ones have it set to 0.

      x86/mm: Warn on W^X mappings

      Warn on any residual W+X mappings after setting NX
      if DEBUG_WX is enabled.  Introduce a separate
      X86_PTDUMP_CORE config that enables the code for
      dumping the page tables without enabling the debugfs
      interface, so that DEBUG_WX can be enabled without
      exposing the debugfs interface.  Switch EFI_PGT_DUMP
      to using X86_PTDUMP_CORE so that it also does not require
      enabling the debugfs interface.

      On success it prints this to the kernel log:

        x86/mm: Checked W+X mappings: passed, no W+X pages found.

      On failure it prints a warning and a count of the failed pages:

      Merge tag 'perf-core-for-mingo' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      User visible changes:

        - Switch the default callchain output mode to 'graph,0.5,caller', to 
make it
          look like the default for other tools, reducing the learning curve for
          people used to 'caller' based viewing. (Arnaldo Carvalho de Melo)

        - Implement column based horizontal scrolling in the hists browser 
(top, report),
          making it possible to use the TUI for things like 'perf mem report' 
where
          there are many more columns than can fit in a terminal. (Arnaldo 
Carvalho de Melo)

        - Support sorting by symbol_iaddr with perf.data files produced by
          'perf mem record'. (Don Zickus)

        - Display DATA_SRC sample type bit, i.e. when running 'perf evlist -v' 
the
          "DATA_SRC" wasn't appearing when set, fix it to look like: (Jiri Olsa)

            cpu/mem-loads/pp: ...SNIP... sample_type: 
IP|TID|TIME|ADDR|CPU|PERIOD|DATA_SRC

        - Introduce the 'P' event modifier, meaning 'max precision level, 
please', i.e.:

           $ perf record -e cycles:P usleep 1

          Is now similar to:

           $ perf record usleep 1

          Useful, for instance, when specifying multiple events. (Jiri Olsa)

        - Make 'perf -v' and 'perf -h' work. (Jiri Olsa)

        - Fail properly when pattern matching fails to find a tracepoint, i.e.
          '-e non:existent' was being correctly handled, with a proper error 
message
          about that not being a valid event, but '-e non:existent*' wasn't,
          fix it. (Jiri Olsa)

      Infrastructure changes:

        - Separate arch specific entries in 'perf test' and add an 'Intel CQM' 
one
          to be fun on x86 only. (Matt Fleming)

      This happened because the same transaction handle created a large number
      of block groups and while finalizing their creation (inserting new items
      and updating existing items in the chunk and device trees) a new metadata
      extent had to be allocated and no free space was found in the current
      metadata block groups, which made find_free_extent() attempt to allocate
      a new block group via do_chunk_alloc(). However at do_chunk_alloc() we
      ended up allocating a new system chunk too and exceeded the threshold
      of 2Mb of reserved chunk bytes, which makes do_chunk_alloc() enter the
      final part of block group creation again (at
      btrfs_create_pending_block_groups()) and attempt to lock again the root
      of the chunk tree when it's already write locked by the same task.

      Similarly we can deadlock on extent tree nodes/leafs if while we are
      running delayed references we end up creating a new metadata block group
      in order to allocate a new node/leaf for the extent tree (as part of
      a CoW operation or growing the tree), as btrfs_create_pending_block_groups
      inserts items into the extent tree as well. In this case we get the
      following trace:

      Btrfs: update fix for read corruption of compressed and shared extents

      My previous fix in commit 005efedf2c7d ("Btrfs: fix read corruption of
      compressed and shared extents") was effective only if the compressed
      extents cover a file range with a length that is not a multiple of 16
      pages. That's because the detection of when we reached a different range
      of the file that shares the same compressed extent as the previously
      processed range was done at extent_io.c:__do_contiguous_readpages(),
      which covers subranges with a length up to 16 pages, because
      extent_readpages() groups the pages in clusters no larger than 16 pages.
      So fix this by tracking the start of the previously processed file
      range's extent map at extent_readpages().

      The following test case for fstests reproduces the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"

      Btrfs: send, fix corner case for reference overwrite detection

      When the inode given to did_overwrite_ref() matches the current progress
      and has a reference that collides with the reference of other inode that
      has the same number as the current progress, we were always telling our
      caller that the inode's reference was overwritten, which is incorrect
      because the other inode might be a new inode (different generation number)
      in which case we must return false from did_overwrite_ref() so that its
      callers don't use an orphanized path for the inode (as it will never be
      orphanized, instead it will be unlinked and the new inode created later).

      The following test case for fstests reproduces the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"

        tmp=/tmp/$$

      perf hists browser: Implement horizontal scrolling

      Do it using the recently introduced ui_brower scrolling mode, setting
      ui_browser.columns to the number of sort columns and then, when
      rendering each line, skipping as many initial columns as the user
      pressed the right arrow.

      As the user presses the left arrow, the ui_browser code will remove the
      scrolling counter and the left scrolling takes place.

      The right arrow key was an alias for ENTER, so people used to press it
      may get a bit annoyed at first, sorry! Ditto for ESC and the left key.

      Callchains can be left as is or we can, when rendering the Symbol
      column, store the at what position on the screen it is and then
      using ui_browser__gotorc() to print it from there, i.e. the callchain
      would move around with the symbol.

      Leaving it as is, i.e. at a fixed position, close to the left, saves
      precious screen real state for it, so I'm inclined to leave it as is
      now.

      perf ui browser: Optional horizontal scrolling key binding

      If the classes derived from ui_browser want to do some sort of
      horizontal scrolling, they have just to set ui_browser->columns to
      the number of columns available.

      Those columns can be the number of characters on the screen, if what is
      desired is to scroll character by character, or the number of columns in
      a spreadsheet like table.

      This is what the hist_browser will do, skipping ui_browser->horiz_scroll
      columns when rendering each of its lines.

      perf tests: Add Intel CQM test

      Peter reports that it's possible to trigger a WARN_ON_ONCE() in the
      Intel CQM code by combining a hardware event and an Intel CQM
      (software) event into a group. Unfortunately, the perf tools are not
      able to create this bundle and we need to manually construct a test
      case.

      For posterity, record Peter's proof of concept test case in tools/perf
      so that it presents a model for how we can perform architecture
      specific tests, or "arch tests", in perf in the future.

      The particular issue triggered in the test case is that when the
      counter for the hardware event overflows and triggers a PMI we'll read
      both the hardware event and the software event counters.
      Unfortunately, for CQM that involves performing an IPI to read the CQM
      event counters on all sockets, which in NMI context triggers the
      WARN_ON_ONCE().

      perf tests: Add arch tests

      Tests that only make sense for some architectures currently live in
      the same place as the generic tests. Move out the x86-specific tests
      into tools/perf/arch/x86/tests and define an 'arch_tests' array, which
      is the list of tests that only apply to the build architecture.

      The main idea is to encourage developers to add arch tests to build
      out perf's test coverage, without dumping everything in
      tools/perf/tests.

      perf tools: Handle -h and -v options

      Adding handling for '-h' and '-v' options to invoke help and version
      command respectively.

      Current behaviour is:

         $ perf -v
         Unknown option: -v

          Usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]
         $ perf -h
         Unknown option: -h

          Usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]

      New behaviour:

        $ perf -h

         usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]

         The most commonly used perf commands are:
           annotate        Read perf.data (created by perf record) and display 
annotated code
           archive         Create archive with object files with build-ids 
found in perf.data file
           bench           General framework for benchmark suites
         ...

        $ perf -v
        perf version 4.3.rc3.gc99e32

      perf tools: Add support for sorting on the iaddr

      Sorting on 'symbol' gives to broad a resolution as it can cover a range

      RDS: IB: split mr pool to improve 8K messages performance

      8K message sizes are pretty important usecase for RDS current
      workloads so we make provison to have 8K mrs available from the pool.
      Based on number of SG's in the RDS message, we pick a pool to use.

      Also to make sure that we don't under utlise mrs when say 8k messages
      are dominating which could lead to 8k pull being exhausted, we fall-back
      to 1m pool till 8k pool recovers for use.

      This helps to at least push ~55 kB/s bidirectional data which
      is a nice improvement.

      RDS: IB: ack more receive completions to improve performance

      For better performance, we split the receive completion IRQ handler. That
      lets us acknowledge several WCE events in one call. We also limit the WC
      to max 32 to avoid latency. Acknowledging several completions in one call
      instead of several calls each time will provide better performance since
      less mutual exclusion locks are being performed.

      In next patch, send completion is also split which re-uses the poll_cq()
      and hence the code is moved to ib_cm.c

      RDS: use rds_send_xmit() state instead of RDS_LL_SEND_FULL

      In Transport indepedent rds_sendmsg(), we shouldn't make decisions based
      on RDS_LL_SEND_FULL which is used to manage the ring for RDMA based
      transports. We can safely issue rds_send_xmit() and the using its
      return value take decision on deferred work. This will also fix
      the scenario where at times we are seeing connections stuck with
      the LL_SEND_FULL bit getting set and never cleared.

      RDS: defer the over_batch work to send worker

      Current process gives up if its send work over the batch limit.
      The work queue will get  kicked to finish off any other requests.
      This fixes remainder condition from commit 443be0e5affe ("RDS: make
      sure not to loop forever inside rds_send_xmit").

      The restart condition is only for the case where we reached to
      over_batch code for some other reason so just retrying again
      before giving up.

      While at it, make sure we use already available 'send_batch_count'
      parameter instead of magic value. The batch count threshold value
      of 1024 came via commit 443be0e5affe ("RDS: make sure not to loop
      forever inside rds_send_xmit"). The idea is to process as big a
      batch as we can but at the same time we don't hold other waiting
      processes for send. Hence back-off after the send_batch_count
      limit (1024) to avoid soft-lock ups.

And

      > Add a new flag to indicate .fault is tried once.  In the second try,

      ALSA: synth: Fix conflicting OSS device registration on AWE32

      When OSS emulation is loaded on ISA SB AWE32 chip, we get now kernel
      warnings like:
        WARNING: CPU: 0 PID: 2791 at fs/sysfs/dir.c:31 
sysfs_warn_dup+0x51/0x80()
        sysfs: cannot create duplicate filename 
'/devices/isa/sbawe.0/sound/card0/seq-oss-0-0'

      It's because both emux synth and opl3 drivers try to register their
      OSS device object with the same static index number 0.  This hasn't
      been a big problem until the recent rewrite of device management code
      (that exposes sysfs at the same time), but it's been an obvious bug.

      This patch works around it just by using a different index number of
      emux synth object.  There can be a more elegant way to fix, but it's
      enough for now, as this code won't be touched so often, in anyway.

      Mark Craske says:

      ====================
      Improve ASIX RX memory allocation error handling

      The ASIX RX handler algorithm is weak on error handling.
      There is a design flaw in the ASIX RX handler algorithm because the
      implementation for handling RX Ethernet frames for the DUB-E100 C1 can
      have Ethernet frames spanning multiple URBs. This means that payload data
      from more than 1 URB is sometimes needed to fill the socket buffer with a
      complete Ethernet frame. When the URB with the start of an Ethernet frame
      is received then an attempt is made to allocate a socket buffer. If the
      memory allocation fails then the algorithm sets the buffer pointer member
      to NULL and the function exits (no crash yet). Subsequently, the RX hander
      is called again to process the next URB which assumes there is a socket
      buffer available and the kernel crashes when there is no buffer.

      This patchset implements an improvement to the RX handling algorithm to
      avoid a crash when no memory is available for the socket buffer.

      The patchset will apply cleanly to the net-next master branch but the
      created kernel has not been tested. The driver was tested on ARM kernels
      v3.8 and v3.14 for a commercial product.

      asix: Continue processing URB if no RX netdev buffer

      Avoid a loss of synchronisation of the Ethernet Data header 32-bit
      word due to a failure to get a netdev socket buffer.

      The ASIX RX handling algorithm returned 0 upon a failure to get
      an allocation of a netdev socket buffer. This causes the URB
      processing to stop which potentially causes a loss of synchronisation
      with the Ethernet Data header 32-bit word. Therefore, subsequent
      processing of URBs may be rejected due to a loss of synchronisation.
      This may cause additional good Ethernet frames to be discarded
      along with outputting of synchronisation error messages.

      Implement a solution which checks whether a netdev socket buffer
      has been allocated before trying to copy the Ethernet frame into
      the netdev socket buffer. But continue to process the URB so that
      synchronisation is maintained. Therefore, only a single Ethernet
      frame is discarded when no netdev socket buffer is available.

      asix: On RX avoid creating bad Ethernet frames

      When RX Ethernet frames span multiple URB socket buffers,
      the data stream may suffer a discontinuity which will cause
      the current Ethernet frame in the netdev socket buffer
      to be incomplete. This frame needs to be discarded instead
      of appending unrelated data from the current URB socket buffer
      to the Ethernet frame in the netdev socket buffer. This avoids
      creating a corrupted Ethernet frame in the netdev socket buffer.

      A discontinuity can occur when the previous URB socket buffer
      held an incomplete Ethernet frame due to truncation or a
      URB socket buffer containing the end of the Ethernet frame
      was missing.

      Therefore, add a sanity test for when an Ethernet frame
      spans multiple URB socket buffers to check that the remaining
      bytes of the currently received Ethernet frame point to
      a good Data header 32-bit word of the next Ethernet
      frame. Upon error, reset the remaining bytes variable to
      zero and discard the current netdev socket buffer.
      Assume that the Data header is located at the start of
      the current socket buffer and attempt to process the next
      Ethernet frame from there. This avoids unnecessarily

      asix: Simplify asix_rx_fixup_internal() netdev alloc

      The code is checking that the Ethernet frame will fit into a
      netdev allocated socket buffer within the constraints of MTU size,
      Ethernet header length plus VLAN header length.

      The original code was checking rx->remaining each loop of the while
      loop that processes multiple Ethernet frames per URB and/or Ethernet
      frames that span across URBs. rx->remaining decreases per while loop
      so there is no point in potentially checking multiple times that the
      Ethernet frame (remaining part) will fit into the netdev socket buffer.

      The modification checks that the size of the Ethernet frame will fit
      the netdev socket buffer before allocating the netdev socket buffer.
      This avoids grabbing memory and then deciding that the Ethernet frame
      is too big and then freeing the memory.

      asix: Tidy-up 32-bit header word synchronisation

      Tidy-up the Data header 32-bit word synchronisation logic in
      asix_rx_fixup_internal() by removing redundant logic tests.

      The code is looking at the following cases of the Data header
      32-bit word that is present before each Ethernet frame:

      a) all 32 bits of the Data header word are in the URB socket buffer
      b) first 16 bits of the Data header word are at the end of the URB
         socket buffer
      c) last 16 bits of the Data header word are at the start of the URB
         socket buffer eg. split_head = true

      Note that the lifetime of rx->split_head exists outside of the
      function call and is accessed per processing of each URB. Therefore,
      split_head being true acts on the next URB to be processed.

      To check for b) the offset will be 16 bits (2 bytes) from the end of
      the buffer then indicate split_head is true.
      To check for c) split_head must be true because the first 16 bits
      have been found.
      To check for a) else c)

      Note that the || logic of the old code included the state
      (skb->len - offset == sizeof(u16) && rx->split_head) which is not
      possible because the split_head cannot be true whilst checking for b).
      This is because the split_head indicates that the first 16 bits have
      been found and that is not possible whilst checking for the first 16
      bits. Therefore simplify the logic.

      asix: Rename remaining and size for clarity

      The Data header synchronisation is easier to understand
      if the variables "remaining" and "size" are renamed.

      Therefore, the lifetime of the "remaining" variable exists
      outside of asix_rx_fixup_internal() and is used to indicate
      any remaining pending bytes of the Ethernet frame that need
      to be obtained from the next socket buffer. This allows an
      Ethernet frame to span across multiple socket buffers.

      "size" is now local to asix_rx_fixup_internal() and contains
      the size read from the Data header 32-bit word.

      Add "copy_length" to hold the number of the Ethernet frame
      bytes (maybe a part of a full frame) that are to be copied
      out of the socket buffer.

      bpf, seccomp: prepare for upcoming criu support

      The current ongoing effort to dump existing cBPF seccomp filters back
      to user space requires to hold the pre-transformed instructions like
      we do in case of socket filters from sk_attach_filter() side, so they
      can be reloaded in original form at a later point in time by utilities
      such as criu.

      To prepare for this, simply extend the bpf_prog_create_from_user()
      API to hold a flag that tells whether we should store the original
      or not. Also, fanout filters could make use of that in future for
      things like diag. While fanout filters already use bpf_prog_destroy(),
      move seccomp over to them as well to handle original programs when
      present.

      The underlying issue is the very same as in commit b382c0865600
      ("sock, diag: fix panic in sock_diag_put_filterinfo"), that is,
      native eBPF programs don't store an original program since this
      is only needed in cBPF ones.

      However, sk_get_filter() wasn't updated to test for this at the
      time when eBPF could be attached. Just throw an error to the user
      to indicate that eBPF cannot be dumped over this interface.
      That way, it can also be known that a program _is_ attached (as
      opposed to just return 0), and a different (future) method needs
      to be consulted for a dump.

      After commit 1ce87720d456 ("net: sched: make cls_u32 lockless")
      we began to release tc actions in a RCU callback. However,
      mirred action relies on RTNL lock to protect the global
      mirred_list, therefore we could have a race condition
      between RCU callback and netdevice event, which caused
      a list corruption as reported by Vinson.

      Instead of relying on RTNL lock, introduce a spinlock to
      protect this list.

      Note, in non-bind case, it is still called with RTNL lock,
      therefore should disable BH too.

      iwlwifi: mvm: add minimal multi-RXQ infrastructure

      Since the new multi-queue capability depends on a new firmware API,
      we can already add some code for it. If the new API is present, a
      new opmode ops struct is used that handles the new rx_rss method.

      For now, only restructure the RX handling to distinguish between
      the two. Future patches will convert the new infrastructure to
      actually use the new RX descriptor layout.

scenarios

      This is a tweak which has been shown to improve performance when
      moving away from the AP while working in 80Mhz.
      When RS decides to go down to 80MHz SISO MCS0 instead switch to 20MHz 
MCS4.
      Go back to 80MHz MCS1 if RS can sustain 20MHz MCS5.

      iwlwifi: mvm: rs: fix success ratio comparison in rs_get_best_rate

      success_ratio is actually 128 * SR in percentage while
      IWL_MVM_RS_SR_NO_DECREASE is 85%. Fix this by using RS_PERCENT().
      This bug caused the if branch to be always executed. This in turn
      led to always selecting a rate, following a column switch, in which
      the expected throughput would exceed the best expected current throughput.
      In some scenarios where the success ratio isn't >85% such a rate
      could be too aggressive leading us to avoid the new column.
      This has the potential of causing sub optimal performance.

      iwlwifi: mvm: stop using DEVICE_POWER_FLAGS_CAM_MSK

      The firmware has always treated these two bits to mean that
      powersave is enabled when POWER_SAVE_ENA is set and CAM is
      clear; it doesn't use them in any non-combined way.

      Therefore, it's pointless to send it two bits, and the API
      should be cleaned up. Prepare the driver by removing the CAM
      bit and using only POWER_SAVE_ENA to indicate whether PS is
      enabled or not.

      iwlwifi: mvm: support using multiple ACs on single HW queue

      "DQA" is shorthand for "dynamic queue allocation", with the
      idea of allocating queues per-RA/TID on-demand rather than
      using shared queues statically allocated per vif. The goal
      of this is to enable future features (like GO PM) and to
      improve performance measurements of TX traffic.

      When RA/TID streams can't be neatly sorted into different AC
      queues, DQA allows sharing queues for the same RA. This means
      that DQA allows different ACs may reach the same HW queue.

      Update the code to allow such queue sharing by having a mapping
      between the HW queue and the mac80211 queues using it (as this
      could be more than one queue).

      In this case, it makes no sense to go through the full RX dispatch
      since it's already known that only a subset of the possibilities

      know which queue the packet was received on.

      iwlwifi: mvm: clear csa countdown when AP is stopped

      The csa_countdown flag was not cleared when the AP is stopped.
      As a result, if the AP was stopped after csa_countdown had started,
      all the folowing channel switch commands would fail.
      Fix that by clearing the csa_countdown flag when the AP is stopped.

      enic: do hang reset only in case of tx timeout

      The current code invokes hang reset in case of error interrupt. We should
      hang reset only in case of tx timeout. This because of the way hang reset
      is implemented in firmware. Hang reset takes more firmware resources than
      soft reset. Adaptor does not generate error interrupt in case of tx
      timeout.

      Hang reset only in case of tx timeout, in .ndo_tx_timeout. Do soft reset
      otherwise. Introduce deferred work, enic_tx_hang_reset, to do hang reset.

      iwlwifi: mvm: fix D3 CCMP TX PN assignment

      When going into/coming out of D3, the TX PN must be programmed into
      and restored from the firmware respectively. The restore was broken
      due to my previous commit to move PN assignment into the driver.
      Sending the PN to the firmware still worked since we now use the
      counter that's shared with mac80211, but accessing it through the
      mac80211 API makes no sense now.

      Fix this by reading/writing the counter directly. This actually
      simplifies the code since we don't need to round-trip through the
      key_seq structure.

      RDS: RDS-TCP perf enhancements

      A 3-part patchset that (a) improves current RDS-TCP perf
      by 2X-3X and (b) refactors earlier robustness code for
      better observability/scaling.

      Patch 1 is an enhancment of earlier robustness fixes
      that had used separate sockets for client and server endpoints to
      resolve race conditions. It is possible to have an equivalent
      solution that does not use 2 sockets. The benefit of a
      single socket solution is that it results in more predictable
      and observable behavior for the underlying TCP pipe of an
      RDS connection

      Patches 2 and 3 are simple, straightforward perf bug fixes
      that align the RDS TCP socket with other parts of the kernel stack.

      RDS-TCP: Do not bloat sndbuf/rcvbuf in rds_tcp_tune

      Using the value of RDS_TCP_DEFAULT_BUFSIZE (128K)

      results in significantly better performance.

      In request-response tests using rds-stress with a packet size of
      100K with 16 threads (test parameters -q 100000 -a 256 -t16 -d16)
      between a single pair of IP addresses achieves a throughput of

      RDS: Use a single TCP socket for both send and receive.

      Commit f711a6ae062c ("net/rds: RDS-TCP: Always create a new rds_sock
      for an incoming connection.") modified rds-tcp so that an incoming SYN
      would ignore an existing "client" TCP connection which had the local
      port set to the transient port.  The motivation for ignoring the existing
      "client" connection in f711a6ae was to avoid race conditions and an
      endless duel of reconnect attempts triggered by a restart/abort of one
      of the nodes in the TCP connection.

      However, having separate sockets for active and passive sides
      is avoidable, and the simpler model of a single TCP socket for
      both send and receives of all RDS connections associated with
      that tcp socket makes for easier observability. We avoid the race
      conditions from f711a6ae by attempting reconnects in rds_conn_shutdown
      if, and only if, the (new) c_outgoing bit is set for RDS_TRANS_TCP.
      The c_outgoing bit is initialized in __rds_conn_create().

      A side-effect of re-using the client rds_connection for an incoming
      SYN is the potential of encountering duelling SYNs, i.e., we
      have an outgoing RDS_CONN_CONNECTING socket when we get the incoming
      SYN. The logic to arbitrate this criss-crossing SYN exchange in
      rds_tcp_accept_one() has been modified to emulate the BGP state
      machine: the smaller IP address should back off from the connection 
attempt.

      ====================
      net: assorted y2038 changes

      This is a set of changes for network drivers and core code to
      get rid of the use of time_t and derived data structures.

      I have a longer set of patches that enables me to build kernels
      with the time_t definition removed completely as a help to find
      y2038 overflow issues. This is the subset for networking that
      contains all code that has a reasonable way of fixing at the
      moment and that is either commonly used (in one of the defconfigs)
      or that blocks building a whole subsystem.

      Most of the patches in this series should be noncontroversial,
      but the last two that I marked [RFC] are a bit tricky and
      need input from people that are more familiar with the code than
      I am. All 12 patches are independent of one another and can
      be applied in any order, so feel free to pick all that look
      good.

      Patches that are not included here are:

       - disabling less common device drivers that I don't have a fix
         for yet, this includes

         We'll get there eventually, or we an add a dependency to ensure
         they are not built on 32-bit kernels that need to survive
         beyond 2038. Most of these should be really easy to fix.

       - recvmmsg/sendmmsg system calls: patches have been sent out
         as part of the syscall series, need a little more work and
         review

       - SIOCGSTAMP/SIOCGSTAMPNS/ ioctl calls: tricky, need to discuss
         with some folks at kernel summit

       - SO_RCVTIMEO/SO_SNDTIMEO/SO_TIMESTAMP/SO_TIMESTAMPNS socket
         opt: similar and related to the ioctl

       - mmapped packet socket: need to create v4 of the API, nontrivial

       - pktgen: sends 32-bit timestamps over network, need to find out
         if using unsigned stamps is good enough

       - af_rxpc: similar to pktgen, uses 32-bit times for deadlines

       - ppp ioctl: patch is being worked on, nontrivial but doable

      net: sctp: avoid incorrect time_t use

      We want to avoid using time_t in the kernel because of the y2038
      overflow problem. The use in sctp is not for storing seconds at
      all, but instead uses microseconds and is passed as 32-bit
      on all machines.

      This patch changes the type to u32, which better fits the use.

      ipv6: use ktime_t for internal timestamps

      The ipv6 mip6 implementation is one of only a few users of the
      skb_get_timestamp() function in the kernel, which is both unsafe
      on 32-bit architectures because of the 2038 overflow, and slightly
      less efficient than the skb_get_ktime() based approach.

      This converts the function call and the mip6_report_rate_limiter
      structure that stores the time stamp, eliminating all uses of
      timeval in the ipv6 code.

      nfnetlink: use y2038 safe timestamp

      The __build_packet_message function fills a nfulnl_msg_packet_timestamp
      structure that uses 64-bit seconds and is therefore y2038 safe, but
      it uses an intermediate 'struct timespec' which is not.

      This trivially changes the code to use 'struct timespec64' instead,
      to correct the result on 32-bit architectures.

      atm: remove 'struct zatm_t_hist'

      The zatm_t_hist structure is not used anywhere in the kernel, but is
      exported to user space. As we are trying to eliminate uses of time_t
      in the kernel for y2038 compatibility, the current definition triggers
      checking tools because it contains 'struct timeval'.

      As pointed out by Chas Williams, the only user of this structure was
      the ZATM_GETHIST ioctl command that has been removed a long time ago,
      and we can remove the structure as well without breaking any user
      space.

      mac80211: use ktime_get_seconds

      The mac80211 code uses ktime_get_ts to measure the connected time.
      As this uses monotonic time, it is y2038 safe on 32-bit systems,
      but we still want to deprecate the use of 'timespec' because most
      other users are broken.

      This changes the code to use ktime_get_seconds() instead, which
      avoids the timespec structure and is slightly more efficient.

      mwifiex: avoid gettimeofday in ba_threshold setting

      mwifiex_get_random_ba_threshold() uses a complex homegrown implementation
      to generate a pseudo-random number from the current time as returned
      from do_gettimeofday().

      This currently requires two 32-bit divisions plus a couple of other
      computations that are eventually discarded as only eight bits of
      the microsecond portion are used at all.

      We could replace this with a call to get_random_bytes(), but that
      might drain the entropy pool too fast if this is called for each
      packet.

      Instead, this patch converts it to use ktime_get_ns(), which is a
      bit faster than do_gettimeofday(), and then uses a similar algorithm
      as before, but in a way that takes both the nanosecond and second
      portion into account for slightly-more-but-still-not-very-random
      pseudorandom number.

      mwifiex: use ktime_get_real for timestamping

      The mwifiex_11n_aggregate_pkt() function creates a ktime_t from
      a timeval returned by do_gettimeofday, which is slow and causes
      an overflow in 2038 on 32-bit architectures.

      This solves both problems by using the appropriate ktime_get_real()
      function.

      net: fec: avoid timespec use

      The fec_ptp_enable_pps uses an open-coded implementation of 
ns_to_timespec,
      which will be removed eventually as it is not y2038-safe on 32-bit
      architectures. Two more instances of the same code in this file were
      already converted to use the safe ns_to_timespec64 in commit 6630514fcee
      ("ptp: fec: use helpers for converting ns to timespec"), this changes
      the last one as well.

      The seconds portion here is actually unused and we could just remove the
      timespec variable, but using ns_to_timespec64 can still be better as the
      implementation can be hand-optimized in the future.

      Merge branch 'ipv4-multipath-hash'

      Peter Nørlund says:

      ====================
      ipv4: Hash-based multipath routing

      When the routing cache was removed in 3.6, the IPv4 multipath algorithm 
changed
      from more or less being destination-based into being quasi-random 
per-packet
      scheduling. This increases the risk of out-of-order packets and makes it
      impossible to use multipath together with anycast services.

      This patch series replaces the old implementation with flow-based load
      balancing based on a hash over the source and destination addresses.

      Distribution of the hash is done with thresholds as described in RFC 2992.
      This reduces the disruption when a path is added/remove when having more 
than
      two paths.

      To futher the chance of successful usage in conjuction with anycast, ICMP
      error packets are hashed over the inner IP addresses. This ensures that 
PMTU
      will work together with anycast or load-balancers such as IPVS.

      Port numbers are not considered since fragments could cause problems with
      anycast and IPVS. Relying on the DF-flag for TCP packets is also 
insufficient,
      since ICMP inspection effectively extracts information from the opposite
      flow which might have a different state of the DF-flag. This is also why 
the
      RSS hash is not used. These are typically based on the NDIS RSS spec which
      mandates TCP support.

      Measurements of the additional overhead of a two-path multipath
      (p_mkroute_input excl. __mkroute_input) on a Xeon X3550 (4 cores, 
2.66GHz):

      Original per-packet: ~394 cycles/packet
      L3 hash:              ~76 cycles/packet

      Changes in v5:
      - Fixed compilation error

      Changes in v4:
      - Functions take hash directly instead of func ptr
      - Added inline hash function
      - Added dummy macros to minimize ifdefs
      - Use upper 31 bits of hash instead of lower

      Changes in v3:
      - Multipath algorithm is no longer configurable (always L3)
      - Added random seed to hash
      - Moved ICMP inspection to isolated function
      - Ignore source quench packets (deprecated as per RFC 6633)

      Changes in v2:
      - Replaced 8-bit xor hash with 31-bit jenkins hash
      - Don't scale weights (since 31-bit)
      - Avoided unnecesary renaming of variables
      - Rely on DF-bit instead of fragment offset when checking for 
fragmentation
      - upper_bound is now inclusive to avoid overflow
      - Use a callback to postpone extracting flow information until necessary
      - Skipped ICMP inspection entirely with L4 hashing
      - Handle newly added sysctl ignore_routes_with_linkdown

      tcp: avoid two atomic ops for syncookies

      inet_reqsk_alloc() is used to allocate a temporary request
      in order to generate a SYNACK with a cookie. Then later,
      syncookie validation also uses a temporary request.

      These paths already took a reference on listener refcount,
      we can avoid a couple of atomic operations.

      tcp: fix fastopen races vs lockless listener

      There are multiple races that need fixes :

      1) skb_get() + queue skb + kfree_skb() is racy

      An accept() can be done on another cpu, data consumed immediately.
      tcp_recvmsg() uses __kfree_skb() as it is assumed all skb found in
      socket receive queue are private.

      Then the kfree_skb() in tcp_rcv_state_process() uses an already freed skb

      2) tcp_reqsk_record_syn() needs to be done before tcp_try_fastopen()
      for the same reasons.

      3) We want to send the SYNACK before queueing child into accept queue,
      otherwise we might reintroduce the ooo issue fixed in

      MIPS: UAPI: Ignore __arch_swab{16,32,64} when using MIPS16

      Some GCC versions (e.g. 4.8.3) can incorrectly inline a function with
      MIPS32 instructions into another function with MIPS16 code [1], causing
      the assembler to genereate incorrect binary code or fail right away
      complaining about unrecognized opcode.

      In the case of __arch_swab{16,32}, when inlined by the compiler with
      flags `-mips32r2 -mips16 -Os', the assembler can fail with the following
      error.

          {standard input}:79: Error: unrecognized opcode `wsbh $2,$2'

      For performance concerns and to workaround the issue already existing in
      older compilers, just ignore these 2 functions when compiling with
      mips16 enabled.

      For at least GCC 4.8.3, adding nomips16 function attribute still cannot
      prevent it from being inlined in mips16 context.  So revert it first in
      preparation for a better workaround.

      gpio: pca953x: store driver_data for future use

      Instead of using id->driver_data directly we copied it to the internal
      structure. This will help to adapt driver for ACPI use.

      Bluetooth: Send transport open and close monitor events

      When the core starts or shuts down the actual HCI transport, send a new
      monitor event that indicates that this is happening. These new events
      correspond to HCI_DEV_OPEN and HCI_DEV_CLOSE events.

      Bluetooth: Move handling of HCI_RUNNING flag into core

      Setting and clearing of HCI_RUNNING flag in each and every driver is
      just duplicating the same code all over the place. So instead of having
      the driver do it in their hdev->open and hdev->close callbacks, set it
      globally in the core transport handling.

      Bluetooth: btbcm: Send HCI Reset before sending Apple specific commands

      The commit 7bee8b08c428 allows the Read Verbose Config Info to fail
      gracefully and not cause the controller setup to abort. It seems the
      reason that command failed in the first place was the missing HCI Reset
      to bring the controller in full Bluetooth mode.

      Apple Bluetooth controllers start out in HID mode and when in that mode
      the Read Verbose Config Info command is not allowed. Sending HCI Reset
      switches the controller into full HCI mode.

      bridge: complete netlink support

      This set completes the bridge device's netlink support and makes it
      possible to view and configure everything that can be configured via
      sysfs. I have tested all of these (setting and getting). There're a few
      longer line warnings about the br_get_size() ifla comments but I think we
      should have them to know what has been accounted for. I have used the 
sysfs
      interface as a guide of what and how to set. As usual I'll send the
      corresponding iproute2 patches later.
      The bridge port's netlink interface will be completed after this set gets
      applied in some form.

      This patch-set is on top of my last vlan cleanups set:

      bridge: vlan: use rcu list for the ordered vlan list

      When I did the conversion to rhashtable I missed the required locking of
      one important user of the vlan list - br_get_link_af_size_filtered()
      which is called:
      br_ifinfo_notify() -> br_nlmsg_size() -> br_get_link_af_size_filtered()
      and the notifications can be sent without holding rtnl. Before this
      conversion the function relied on using rcu and since we already use rcu

      ALSA: hda - Disable power_save_node for IDT 92HD73xx chips

      The recent widget power saving introduced some unavoidable click
      noises on old IDT 92HD73xx chips while it still seems working on the
      compatible new chips.  In the bugzilla, we tried lots of tests and
      workarounds, but they didn't help much.  So, let's disable the feature
      for these specific chips as the least (but safest) fix.

      netfilter: nfnetlink_queue: get rid of nfnetlink_queue_ct.c

      The original intention was to avoid dependencies between nfnetlink_queue 
and
      conntrack without ifdef pollution. However, we can achieve this by moving 
the
      conntrack dependent code into ctnetlink and keep some glue code to access 
the
      nfq_ct indirection from nfqueue.

      After this patch, the nfq_ct indirection is always compiled in the 
netfilter
      core to avoid polluting nfqueue with ifdefs. Thus, if nf_conntrack is not
      compiled this results in only 8-bytes of memory waste in x86_64.

      This patch also adds ctnetlink_nfqueue_seqadj() to avoid that the nf_conn
      structure layout if exposed to nf_queue, which creates another dependency 
with
      nf_conntrack at compilation time.

      tty: fix data race on tty_buffer.commit

      Race on buffer data happens when newly committed data is
      picked up by an old flush work in the following scenario:
      __tty_buffer_request_room does a plain write of tail->commit,
      no barriers were executed before that.
      At this point flush_to_ldisc reads this new value of commit,
      and reads buffer data, no barriers in between.
      The committed buffer data is not necessary visible to flush_to_ldisc.

      Similar bug happens when tty_schedule_flip commits data.

      Update commit with smp_store_release and read commit with
      smp_load_acquire, as it is commit that signals data readiness.
      This is orthogonal to the existing synchronization on tty_buffer.next,
      which is required to not dismiss a buffer with unconsumed data.

      The data race was found with KernelThreadSanitizer (KTSAN).

      tty: fix data race in tty_buffer_flush

      tty_buffer_flush frees not acquired buffers.
      As the result, for example, read of b->size in tty_buffer_free
      can return garbage value which will lead to a huge buffer
      hanging in the freelist. This is just the benignest
      manifestation of freeing of a not acquired object.
      If the object is passed to kfree, heap can be corrupted.

      flush_to_ldisc reads port->itty and checks that it is not NULL,
      concurrently release_tty sets port->itty to NULL. It is possible
      that flush_to_ldisc loads port->itty once, ensures that it is

      can already return NULL, which will cause a crash.

      tty: fix stall caused by missing memory barrier in drivers/tty/n_tty.c

      My colleague ran into a program stall on a x86_64 server, where
      n_tty_read() was waiting for data even if there was data in the buffer
      in the pty.  kernel stack for the stuck process looks like below.
       #0 [ffff88303d107b58] __schedule at ffffffff815c4b20
       #1 [ffff88303d107bd0] schedule at ffffffff815c513e

       #9 [ffff88303d107f50] entry_SYSCALL_64_fastpath at ffffffff815c86d7

      There seems to be two problems causing this issue.

      First, in drivers/tty/n_tty.c, __receive_buf() stores the data and
      updates ldata->commit_head using smp_store_release() and then checks
      the wait queue using waitqueue_active().  However, since there is no
      memory barrier, __receive_buf() could return without calling
      wake_up_interactive_poll(), and at the same time, n_tty_read() could
      start to wait in wait_woken() as in the following chart.

              __receive_buf()                         n_tty_read()
      ------------------------------------------------------------------------
      if (waitqueue_active(&tty->read_wait))
      /* Memory operations issued after the
         RELEASE may be completed before the
         RELEASE operation has completed */
                                              add_wait_queue(&tty->read_wait, 
&wait);
                                              ...
                                              if (!input_available_p(tty, 0)) {
      smp_store_release(&ldata->commit_head,
                        ldata->read_head);
                                              ...
                                              timeout = wait_woken(&wait,
                                                TASK_INTERRUPTIBLE, timeout);
      ------------------------------------------------------------------------

      The second problem is that n_tty_read() also lacks a memory barrier
      call and could also cause __receive_buf() to return without calling
      wake_up_interactive_poll(), and n_tty_read() to wait in wait_woken()
      as in the chart below.

              __receive_buf()                         n_tty_read()
      ------------------------------------------------------------------------
                                              spin_lock_irqsave(&q->lock, 
flags);
                                              /* from add_wait_queue() */
                                              ...
                                              if (!input_available_p(tty, 0)) {
                                              /* Memory operations issued after

                                                 RELEASE operation has

      smp_store_release(&ldata->commit_head,
                        ldata->read_head);
      if (waitqueue_active(&tty->read_wait))
                                              __add_wait_queue(q, wait);
                                              
spin_unlock_irqrestore(&q->lock,flags);
                                              /* from add_wait_queue() */
                                              ...
                                              timeout = wait_woken(&wait,
                                                TASK_INTERRUPTIBLE, timeout);
      ------------------------------------------------------------------------

      There are also other places in drivers/tty/n_tty.c which have similar
      calls to waitqueue_active(), so instead of adding many memory barrier
      calls, this patch simply removes the call to waitqueue_active(),
      leaving just wake_up*() behind.

      This fixes both problems because, even though the memory access before
      or after the spinlocks in both wake_up*() and add_wait_queue() can
      sneak into the critical section, it cannot go past it and the critical
      section assures that they will be serialized (please see "INTER-CPU
      ACQUIRING BARRIER EFFECTS" in Documentation/memory-barriers.txt for a
      better explanation).  Moreover, the resulting code is much simpler.

      Latency measurement using a ping-pong test over a pty doesn't show any
      visible performance drop.

      Commit a3a10ce3429e ("Avoid usb reset crashes by making tty_io cdevs truly
      dynamic") which mixes using cdev_alloc() and cdev_init() is problematic.
      Subsequent call to cdev_init() after cdev_alloc() sets kobj release method
      from cdev_dynamic_release() to cdev_default_release() and thus makes it
      impossible to free allocated cdev.

leak
      here if things went wrong.

      Merge branch 'strscpy' of 
git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile

      Pull strscpy string copy function implementation from Chris Metcalf.

      Chris sent this during the merge window, but I waffled back and forth on
      the pull request, which is why it's going in only now.

      The new "strscpy()" function is definitely easier to use and more secure
      than either strncpy() or strlcpy(), both of which are horrible nasty
      interfaces that have serious and irredeemable problems.

      strncpy() has a useless return value, and doesn't NUL-terminate an
      overlong result.  To make matters worse, it pads a short result with
      zeroes, which is a performance disaster if you have big buffers.

      strlcpy(), by contrast, is a mis-designed "fix" for strlcpy(), lacking
      the insane NUL padding, but having a differently broken return value
      which returns the original length of the source string.  Which means
      that it will read characters past the count from the source buffer, and
      you have to trust the source to be properly terminated.  It also makes
      error handling fragile, since the test for overflow is unnecessarily
      subtle.

      strscpy() avoids both these problems, guaranteeing the NUL termination
      (but not excessive padding) if the destination size wasn't zero, and
      making the overflow condition very obvious by returning -E2BIG.  It also
      doesn't read past the size of the source, and can thus be used for
      untrusted source data too.

      So why did I waffle about this for so long?

      Every time we introduce a new-and-improved interface, people start doing
      these interminable series of trivial conversion patches.

      And every time that happens, somebody does some silly mistake, and the
      conversion patch to the improved interface actually makes things worse.
      Because the patch is mindnumbing and trivial, nobody has the attention
      span to look at it carefully, and it's usually done over large swatches
      of source code which means that not every conversion gets tested.

      So I'm pulling the strscpy() support because it *is* a better interface.
      But I will refuse to pull mindless conversion patches.  Use this in
      places where it makes sense, but don't do trivial patches to fix things
      that aren't actually known to be broken.

      MIPS: scall: Always run the seccomp syscall filters

      The MIPS syscall handler code used to return -ENOSYS on invalid
      syscalls. Whilst this is expected, it caused problems for seccomp
      filters because the said filters never had the change to run since
      the code returned -ENOSYS before triggering them. This caused
      problems on the chromium testsuite for filters looking for invalid
      syscalls. This has now changed and the seccomp filters are always
      run even if the syscall is invalid. We return -ENOSYS once we
      return from the seccomp filters. Moreover, similar codepaths have
      been merged in the process which simplifies somewhat the overall
      syscall code.

      usb: Add device quirk for Logitech PTZ cameras

      Add a device quirk for the Logitech PTZ Pro Camera and its sibling the
      ConferenceCam CC3000e Camera.
      This fixes the failed camera enumeration on some boot, particularly on
      machines with fast CPU.

      Tested by connecting a Logitech PTZ Pro Camera to a machine with a
      Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles
      while recording the kernel logs and taking camera picture after each boot.
      Before the patch, more than 7% of the boots show some enumeration transfer
      failures and in a few of them, the kernel is giving up before actually
      enumerating the webcam. After the patch, the enumeration has been correct
      on every reboot.

      i40evf: don't blow away MAC address

      Under certain circumstances, we can get an extra VF_RESOURCES message
      from the PF driver at runtime. When this happens, we need to parse it
      because our VSI may have changed out from underneath us, and that will
      affect our relationship with the PF driver.

      However, parsing the resources message also blows away our current MAC
      address in the hardware struct, usually with all zeros. When this
      happens, the next time the interface is opened, it will have no MAC
      address and will a) not work and b) complain.

      Fix this issue by restoring the current MAC address from the netdev
      struct after we parse the resource message.

      Before letting request sockets being put in TCP/DCCP regular

      - add RCU grace period before freeing them.

      Since we carefully respected the SLAB_DESTROY_BY_RCU protocol
      like ESTABLISH and TIMEWAIT sockets, use it here.

      req_prot_init() being only used by TCP and DCCP, I did not add
      a new slab_flags into their rsk_prot, but reuse prot->slab_flags

      Since all reqsk_alloc() users are correctly dealing with a failure,
      add the __GFP_NOWARN flag to avoid traces under pressure.

      Bluetooth: btintel: Add iBT register access over HCI support

      Add regmap ibt to support Intel Bluetooth silicon register access
      over HCI. Intel BT/FM combo chip allows to read/write some registers
      (e.g. FM registers) via its HCI interface.

      Read/Write operations are performed via a HCI transaction composed of
      a HCI command (host->controller) followed by a HCI command complete
      event (controller->host). Read/Write Command opcodes can be specified
      to the regmap init function.
      We define data formats which are intel/vendor specific.

      Register Read/Write HCI command payload (Host):
      Field: | REG ADDR | MODE | DATA_LEN | DATA... |
      size:  |   32b    |  8b  |    8b    |  8b*    |

      Register Read HCI command complete event payload (Controller):
      Field: | CMD STATUS | REG ADDR | DATA... |
      size:  |     8b     |   32b    |  8b*    |

      Register Write HCI command complete event payload (Controller):
      Field: | CMD_STATUS |
      size:  |     8b     |

      Since this payload is HCI encapsulated, Little Endian byte order is
      used.

      Write/Read Example:

      If we write 0x0000002a at address 0x00008c04, with opcode_write 0xfc5d,
      The resulting transaction is (btmon trace):

      < HCI Command (0x3f|0x005d) plen 10 [hci0]
              04 8c 00 00 02 04 2a 00 00 00
      > HCI Event (0x0e) plen 4
            Unknown (0x3f|0x005d) ncmd 1
              00

      Then, if we read the same register with opcode_read 0xfc5e:

      < HCI Command (0x3f|0x005e) plen 6 [hci0]
              04 8c 00 00 02 04
      > HCI Event (0x0e) plen 12 [hci0]
            Unknown (0x3f|0x005e) ncmd 1

      (e.g. a SysRq issued using UART or kbd) the main CPU will wedge for ten
      seconds with interrupts masked before issuing a backtrace for every CPU
      except itself.

      The new backtrace code introduced by commit 96f0e00378d4 ("ARM: add
      basic support for on-demand backtrace of other CPUs") does not work
      correctly when run from an interrupt handler because IPI_CPU_BACKTRACE
      is used to generate the backtrace on all CPUs but cannot preempt the
      current calling context.

      This can be fixed by detecting that the calling context cannot be
      preempted and issuing the backtrace directly in this case. Issuing
      directly leaves us without any pt_regs to pass to nmi_cpu_backtrace()
      so we also modify the generic code to call dump_stack() when its
      argument is NULL.

      ARM: 8428/1: kgdb: Fix registers on sleeping tasks

      Dumping registers from other sleeping tasks in KGDB was totally
      failing for me.  All registers were reported as 0 in many cases.

      The code was using task_pt_regs(task) to try to get other thread
      registers.  This doesn't appear to be the right place to look.  From
      my tests, I saw non-zero values in this structure when we were looking
      at a kernel thread that had a userspace task associated with it, but
      it contained the register values from the userspace task.  So even in
      the cases where registers weren't reported as 0 we were still not
      showing the right thing.

      Instead of using task_pt_regs(task) let's use task_thread_info(task).
      This is the same place that is referred to when doing a dump of all
      sleeping task stacks (kdb_show_stack() -> show_stack() ->
      dump_backtrace() -> unwind_backtrace() -> thread_saved_sp()).

      As further evidence that this is the right thing to do, you can find
      the following comment in "gdbstub.c" right before it calls
      sleeping_thread_to_gdb_regs():
        Pull stuff saved during switch_to; nothing else is accessible (or
        even particularly relevant).  This should be enough for a stack
        trace.
      ...and if you look at switch_to() it only saves r4-r11, sp and lr.
      Those are the same registers that I'm getting out of the
      task_thread_info().

      With this change you can use "info thread" to see all tasks in the
      kernel and you can switch to other tasks and examine them in gdb.

      ARM: remove user cmpxchg syscall

      Mark Brand reports that a NEEDS_SYSCALL_FOR_CMPXCHG enabled kernel would
      open a security hole in the ghost syscall used to implement cmpxchg, as
      it fails to validate the user pointer.

      However, in order for this option to be enabled, you'd need to be
      building a pre-ARMv6 kernel with SMP support.  There is only one system
      known which fits that, which is an early ARM SMP FPGA implementation
      based on the ARM926T.

      In any case, the Kconfig does not allow SMP to be enabled for pre-ARMv6
      systems.

      Moreover, even if NEEDS_SYSCALL_FOR_CMPXCHG were to be enabled, the
      kernel would not build as __ARM_NR_cmpxchg64 is not defined.

      The simple answer is to remove the buggy code.

      This reverts commit 904464b91eca8c665acea033489225af02eeb75a.

      The problem pointed out by commit 904464b91eca ("ARM: 7655/1:

      doesn't exist anymore.

      We can safely boot with nosmp and the warning won't show up.

      The other side benefit of this patch is that TWD has a chance
      to probe on single-core A9 systems such as AM437x which sport
      TWD.

      While at that, also drop SMP dependency from TWD's Kconfig entry.

      Intel Wired LAN Driver Updates 2015-09-30

      This series contains updates to i40e and i40evf only.

      Vasily Averin provides a couple of rtnl lock/unlock fixes for both i40e
      and i40evf.

      Shannon provides several updates and fixes, first fixes up a type clash
      in i40e_aq_rc_to_posix(), where the error codes are signed values, so we
      need to treat them as such.  Then fixes up a padding issue where an
      extra byte is added in i40e_aqc_get_cee_dcb_cfg_v1_resp to directly
      acknowledge the padding.  Updated i40e to keep debugfs register read
      and writes from accessing outside of the io-remapped space.  Added
      support and device id for another 20 GbE device.

      Jesse fixes the transmit hand workaround code for ARM that was causing
      Tx hangs to still occur occasionally when there really was no hang.  Then
      fixed the receive dropped counter to show up in netstat interface.
      Refactor the interrupt enable function since it was always making the
      caller add the base_vector from the VSI struct which is already passed
      to the function.  Fix kbuild warnings found in 0day build infrastructure
      by adding a harmless cast to a dev_info(), also fix 32 bit build
      warnings found by sparse.

      Greg fixed a configuration error that results if a port VLAN is set
      for a VF before the VF driver is loaded, so that when the VF driver is
      loaded the port VLAN is ignored.

      Mitch fixes the use of QOS field consistently in
      i40e_ndo_set_vf_port_vlan().  Modified the init timing of the driver
      to increase stability on load/unload and SR-IOV enable/disable cycles.

      Anjali updates i40e to not collect VEB stats if they are disabled in the
      hardware for performance reasons.

      ravb: Add support for r8a7795 SoC

      This patch supports the r8a7795 SoC by:
      - Using two interrupts
        + One for E-MAC
        + One for everything else
        + Both can be handled by the existing common interrupt handler, which
          affords a simpler update to support the new SoC. In future some
          consideration may be given to implementing multiple interrupt handlers
      - Limiting the phy speed to 100Mbit/s for the new SoC;
        at this time it is not clear how this restriction may be lifted
        but I hope it will be possible as more information comes to light

      - Adding 25 named interrupts to binding for the new SoC;
        older SoCs continue to use a single multiplexed interrupt

      The example is also updated to reflect the r8a7795 as this is the
      more complex case.

      phylib: Add phy_set_max_speed helper

      Add a helper to allow ethernet drivers to limit the speed of a phy
      (that they are attached to).

      This mainly involves factoring out the business-end of
      of_set_phy_supported() and exporting a new symbol.

      This code seems to be open coded in several places, in several different
      variants.

      It is is envisaged that this will be used in situations where setting the
      "max-speed" property in DT is not appropriate, e.g. because the maximum
      speed is not a property of the phy hardware.

      sched, bpf: add helper for retrieving routing realms

      Using routing realms as part of the classifier is quite useful, it
      can be viewed as a tag for one or multiple routing entries (think of
      an analogy to net_cls cgroup for processes), set by user space routing
      daemons or via iproute2 as an indicator for traffic classifiers and
      later on processed in the eBPF program.

      Unlike actions, the classifier can inspect device flags and enable
      netif_keep_dst() if necessary. tc actions don't have that possibility,
      but in case people know what they are doing, it can be used from there
      as well (e.g. via devs that must keep dsts by design anyway).

      If a realm is set, the handler returns the non-zero realm. User space
      can set the full 32bit realm for the dst.

      ebpf: migrate bpf_prog's flags to bitfield

      As we need to add further flags to the bpf_prog structure, lets migrate
      both bools to a bitfield representation. The size of the base structure
      (excluding insns) remains unchanged at 40 bytes.

      Add also tags for the kmemchecker, so that it doesn't throw false
      positives. Even in case gcc would generate suboptimal code, it's not
      being accessed in performance critical paths.

      switchdev: bring back switchdev_obj

      Second version of the patch extends to a patchset. Basically this patchset
      brings object structure back which disappeared with recent Vivien's 
patchset.
      Also it does a bit of naming changes in order to get the things in line.
      Also, object id is put back into object structure.

      ====================
      tcp/dccp: lockless listener

      TCP listener refactoring : this is becoming interesting !

      This patch series takes the steps to use normal TCP/DCCP ehash
      table to store SYN_RECV requests, instead of the private per-listener
      hash table we had until now.

      SYNACK skb are now attached to their syn_recv request socket,
      so that we no longer heavily modify listener sk_wmem_alloc.

      listener lock is no longer held in fast path, including
      SYNCOOKIE mode.

      During my tests, my server was able to process 3,500,000
      SYN packets per second on one listener and still had available
      cpu cycles.

      That is about 2 to 3 order of magnitude what we had with older kernels.

      This effort started two years ago and I am pleased to reach expectations.

      We'll probably extend SO_REUSEPORT to add proper cpu/numa affinities,
      so that heavy duty TCP servers can get proper siloing thanks to 
multi-queues
      NIC.

      strict semantic for listeners, and use regular RCU.

      tcp: attach SYNACK messages to request sockets instead of listener

      If a listen backlog is very big (to avoid syncookies), then
      the listener sk->sk_wmem_alloc is the main source of false
      sharing, as we need to touch it twice per SYNACK re-transmit
      and TX completion.

      (One SYN packet takes listener lock once, but up to 6 SYNACK
      are generated)

      By attaching the skb to the request socket, we remove this
      source of contention.

      Tested:

       listen(fd, 10485760); // single listener (no SO_REUSEPORT)
       16 RX/TX queue NIC
       Sustain a SYNFLOOD attack of ~320,000 SYN per second,
       Sending ~1,400,000 SYNACK per second.

      tcp/dccp: install syn_recv requests into ehash table

      In this patch, we insert request sockets into TCP/DCCP
      regular ehash table (where ESTABLISHED and TIMEWAIT sockets
      are) instead of using the per listener hash table.

      ACK packets find SYN_RECV pseudo sockets without having
      to find and lock the listener.

      In nominal conditions, this halves pressure on listener lock.

      Note that this will allow for SO_REUSEPORT refinements,
      so that we can select a listener using cpu/numa affinities instead
      of the prior 'consistent hash', since only SYN packets will
      apply this selection logic.

      We will shrink listen_sock in the following patch to ease
      code review.

      iio: st_accel: fix interrupt handling on LIS3LV02

      This accelerometer accidentally either emits a DRDY signal or an
      IRQ signal. Accidentally I activated the IRQ signal as I thought
      it was analogous to the interrupt generator on other ST
      accelerometers. This was wrong. After this patch generic_buffer
      gives a nice stream of accelerometer readings.

      rtlwifi: rtl8821ae: Fix system lockups on boot

      In commit 1277fa2ab2f9 ("rtlwifi: Remove the clear interrupt routine from 
all
      drivers"), the code that cleared all interrupt enable bits before setting 
them
      was removed for all PCI drivers. This fixed an issue that caused TX to be
      blocked for 3-5 seconds. On some RTL8821AE units, this change causes soft
      lockups to occur on boot. For that reason, the portion of the earlier 
commit
      that applied to rtl8821ae is reverted. Kernels 4.1 and newer are affected.

      See http://marc.info/?l=linux-wireless&m=144373370103285&w=2 and
      https://bugzilla.opensuse.org/show_bug.cgi?id=944978 for two cases where
      this regression affected user systems. Note that this bug does not appear 
on
      any of the developer's setups. For those users whose systems are affected
      by the TX blockage, but do not lock up on boot, a module parameter is 
added
      to disable the interrupt clear

      NFC: nci: Use __nci_request for exported routines

      Since we do not know in which context drivers will call these
      routines, they should use the unlocked version of nci_request,
      i.e. __nci_request.
      It is up to drivers to know/decide if they need to take the
      req_lock mutex before calling those routines. When being called
      from the NCI setup routine there is no need to do so as ops->setup
      is called under req_lock.

      This patch fixes one cases where abs() was being used with 64-bit
      nanosecond values, where the result may be capped at 32-bits.

      This potentially could cause watchdog false negatives on 32-bit
      systems, so this patch addresses the issue by using abs64().

      gpio: omap: convert to use generic irq handler

      This patch converts TI OMAP GPIO driver to use generic irq handler
      instead of chained IRQ handler. This way OMAP GPIO driver will be
      compatible with RT kernel where it will be forced thread IRQ handler
      while in non-RT kernel it still will be executed in HW IRQ context.
      As part of this change the IRQ wakeup configuration is applied to
      GPIO Bank IRQ as it now will be under control of IRQ PM Core during
      suspend.

      There are also additional benefits:
       - on-RT kernel there will be no complains any more about PM runtime usage
         in atomic context  "BUG: sleeping function called from invalid 
context";
       - GPIO bank IRQs will appear in /proc/interrupts and its usage statistic
          will be  visible;
       - GPIO bank IRQs could be configured through IRQ proc_fs interface and,
         as result, could be a part of IRQ balancing process if needed;
       - GPIO bank IRQs will be under control of IRQ PM Core during
         suspend to RAM.

      Disadvantage:
       - additional runtime overhed as call chain till
         omap_gpio_irq_handler() will be longer now
       - necessity to use wa_lock in omap_gpio_irq_handler() to W/A warning
         in handle_irq_event_percpu()
         WARNING: CPU: 1 PID: 35 at kernel/irq/handle.c:149 
handle_irq_event_percpu+0x51c/0x638()

      This patch doesn't fully follows recommendations provided by Sebastian
      Andrzej Siewior [1], because It's required to go through and check all
      GPIO IRQ pin states as fast as possible and pass control to 
handle_level_irq
      or handle_edge_irq. handle_level_irq or handle_edge_irq will perform 
actions
      specific for IRQ triggering type and wakeup corresponding registered
      threaded IRQ handler (at least it's expected to be threaded).
      IRQs can be lost if handle_nested_irq() will be used, because excecution
      time of some pin specific GPIO IRQ handler can be very significant and
      require accessing ext. devices (I2C).

      Idea of such kind reworking was also discussed in [2].

      perf stat: Reduce min --interval-print to 10ms

      The --interval-print parameter was limited to 100ms. However, for
      example, 10ms is required to do sophisticated bandwidth analysis using
      uncore events.

      The test shows that the overhead of the system-wide uncore monitoring
      with 10ms interval is only ~2%. So this patch reduces the minimal
      interval-print allowd to 10ms.

      But 10ms may not work well for all cases. For example, when the
      cpus/threads number is very large, for system-wide core event monitoring
      the overhead could be high.

      To handle this issue, a warning will be displayed when the
      interval-print is set between 10ms to 100ms. So users can make a
      decision according to their specific cases.

       # perf stat -e uncore_imc_1/cas_count_read/ -a --interval-print 10 -- 
sleep 1

       print interval < 100ms. The overhead percentage could be high in some
       cases. Please proceed with caution.

      nfs4: reset states to use open_stateid when returning delegation 
voluntarily

      When the client goes to return a delegation, it should always update any
      nfs4_state currently set up to use that delegation stateid to instead
      use the open stateid. It already does do this in some cases,
      particularly in the state recovery code, but not currently when the
      delegation is voluntarily returned (e.g. in advance of a RENAME).  This
      causes the client to try to continue using the delegation stateid after
      the DELEGRETURN, e.g. in LAYOUTGET.

      Set the nfs4_state back to using the open stateid in
      nfs4_open_delegation_recall, just before clearing the
      NFS_DELEGATED_STATE bit.

      NFSv4: Don't try to reclaim unused state owners

      Currently, we don't test if the state owner is in use before we try to
      recover it. The problem is that if the refcount is zero, then the
      state owner will be waiting on the lru list for garbage collection.
      The expectation in that case is that if you bump the refcount, then
      you must also remove the state owner from the lru list. Otherwise
      the call to nfs4_put_state_owner will corrupt that list by trying
      to add our state owner a second time.

      Avoid the whole problem by just skipping state owners that hold no
      state.

      being inconsistent with the behaviour of the equivalent readpage/readpages

      perf record: Change 'record.samples' type to unsigned long long

      When run "perf record -e", the number of samples showed up is wrong on 
some
      32 bit systems, i.e. powerpc and arm.

      For example, run the below commands on 32 bit powerpc:

        perf probe -x /lib/libc.so.6 malloc
        perf record -e probe_libc:malloc -a ls perf.data
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.036 MB perf.data 
(13829241621624967218 samples) ]

      Actually, "perf script" just shows 21 samples. The number of samples is 
also
      absurd since samples is long type, but it is printed as PRIu64.

      Build test ran on x86-64, x86, aarch64, arm, mips, ppc and ppc64.

      perf probe: Allow probing on kmodules without dwarf

      Allow probing on kernel modules when 'perf' is built without debuginfo
      support.

      Currently perf-probe --module requires linking with libdw, but this
      doesn't make sense.

      E.g.
        ----
        # make NO_DWARF=1
        # ./perf probe -m pcspkr pcspkr_event%return
          Error: unknown switch `m'

        Added new event:
          probe:pcspkr_event   (on pcspkr_event%return in pcspkr)

        You can now use it in all perf tools, such as:

      irqchip/gic-v3-its: Count additional LPIs for the aliased devices

      When configuring the interrupt mapping for a new device, we
      iterate over all the possible aliases to account for their
      maximum MSI allocation. This was introduced by e8137f4f5088
      ("irqchip: gicv3-its: Iterate over PCI aliases to generate ITS 
configuration").

      Turns out that the code doing that is a bit braindead, and repeatedly
      accounts for the same device over and over.

      Fix this by counting the actual alias that is passed to us by the
      core code.

      The warning is fairly benign (there is no code path that could

      by zeroing the variables on the error path.

      Pull block fixes from Jens Axboe:
       "Another week, another round of fixes.

        These have been brewing for a bit and in various iterations, but I
        feel pretty comfortable about the quality of them.  They fix real
        issues.  The pull request is mostly blk-mq related, and the only one
        not fixing a real bug, is the tag iterator abstraction from Christoph.
        But it's pretty trivial, and we'll need it for another fix soon.

        Apart from the blk-mq fixes, there's an NVMe affinity fix from Keith,
        and a single fix for xen-blkback from Roger fixing failure to free
        requests on disconnect"

      * 'for-linus' of git://git.kernel.dk/linux-block:

      perf list: Honour 'event_glob' whem printing selectable PMUs

      Some PMUs, like the 'intel_bts' one can be used as an event name, i.e.:

        $ perf record -e intel_bts:// usleep 1

      Is a valid event name.

      But the code printing such PMUs was not honouring the 'event_glob'
      parameter, so the following line was always appearing:

        $ intel_bts//                                        [Kernel PMU event]

      Fix it:

      MIPS: Octeon: Fix kernel panic on startup from memory corruption

      During development it was found that a number of builds would panic
      during the kernel init process, more specifically in 'delayed_fput()'.
      The panic showed the kernel trying to access a memory address of
      '0xb7fdc00' while traversing the 'delayed_fput_list' structure.
      Comparing this memory address to the value of the pointer used on
      builds that did not panic confirmed that the pointer on crashing
      builds must have been corrupted at some stage earlier in the init
      process.

      By traversing the list earlier and earlier in the code it was found
      that 'plat_mem_setup()' was responsible for corrupting the list.
      Specifically the line:

          memory = cvmx_bootmem_phy_alloc(mem_alloc_size,
                        __pa_symbol(&__init_end), -1,
                        0x100000,
                        CVMX_BOOTMEM_FLAG_NO_LOCKING);

      Which would eventually call:

          cvmx_bootmem_phy_set_size(new_ent_addr,
                cvmx_bootmem_phy_get_size
                (ent_addr) -
                (desired_min_addr -
                        ent_addr));

      Where 'new_ent_addr'=0x4800000 (the address of 'delayed_fput_list')
      and the second argument (size)=0xb7fdc00 (the address causing the
      kernel panic). The job of this part of 'plat_mem_setup()' is to
      allocate chunks of memory for the kernel to use. At the start of
      each chunk of memory the size of the chunk is written, hence the
      value 0xb7fdc00 is written onto memory at 0x4800000, therefore the
      kernel panics when it goes back to access 'delayed_fput_list' later
      on in the initialisation process.

      On builds that were not crashing it was found that the compiler had
      placed 'delayed_fput_list' at 0x4800008, meaning it wasn't corrupted
      (but something else in memory was overwritten).

      As can be seen in the first function call above the code begins to
      allocate chunks of memory beginning from the symbol '__init_end'.
      The MIPS linker script (vmlinux.lds.S) however defines the .bss
      section to begin after '__init_end'. Therefore memory within the
      .bss section is allocated to the kernel to use (System.map shows
      'delayed_fput_list' and other kernel structures to be in .bss).

      To stop the kernel panic (and the .bss section being corrupted)
      memory should begin being allocated from the symbol '_end'.

      MIPS: Fix R2300 FP context switch handling

      Commit 1a3d59579b9f ("MIPS: Tidy up FPU context switching") removed FP
      context saving from the asm-written resume function in favour of reusing
      existing code to perform the same task. However it only removed the FP
      context saving code from the r4k_switch.S implementation of resume.
      Remove it from the r2300_switch.S implementation too in order to prevent
      attempting to save the FP context twice, which would likely lead to an
      exception from the second save because the FPU had already been disabled
      by the first save.

      This patch has only been build tested, using rbtx49xx_defconfig.

      Octeon uses its own implementation in octeon_switch.S, so remove FP

      twice. That formerly led to an exception from the second save as follows
      because the FPU had already been disabled by the first save:

      ASoC: dwc: fix dma stop transferring issue

      Designware I2S uses tx empty and rx available signals as the DMA
      handshaking signals. during music playing, if XRUN occurs,
      i2s_stop() function will be executed and both tx and rx irq are
      masked, when music continues to be played, i2s_start() is executed
      but both tx and rx irq are not unmasked which cause I2S stop
      sending DMA handshaking signal to DMA controller, and it finally
      causes music playing will be stopped once XRUN occurs for the first
      time.

      dm raid: fix round up of default region size

      Commit 3a0f9aaee028 ("dm raid: round region_size to power of two")
      intended to make sure that the default region size is a power of two.
      However, the logic in that commit is incorrect and sets the variable
      region_size to 0 or 1, depending on whether min_region_size is a power
      of two.

      Fix this logic, using roundup_pow_of_two(), so that region_size is
      properly rounded up to the next power of two.

      gpio: add DT bindings for existing consumer flags

      It is customary for GPIO controllers to support open drain/collector
      and open source/emitter configurations. Add standard GPIO line flags
      to account for this and augment the documentation to say that these
      are the most generic bindings.

      Several people approached me to add new flags to the lines, and this
      makes sense, but let's first bind up the most common cases before we
      start to add exotic stuff.

      Thanks to H. Nikolaus Schaller for ideas on how to encode single-ended
      wiring such as open drain/source and open collector/emitter.

      gpio: gpiolib: don't compare an unsigned for >= 0

      The parameter offset is an unsigned, so it makes no sense to compare
      it for >= 0. Fix the compiler warning regarding this by removing this
      comparison.

      As the macro GPIO_OFFSET_VALID is only used at this single place, simplify
      the code by dropping the macro completely and dropping the invert, too.

      gpio: zynq: use container_of() to get state container

      The state container of the Zynq GPIO driver is sometimes
      extracted from the gpio_chip exploiting the fact that offsetof()
      the struct gpio_chip inside the struct zynq_gpio is 0, so
      the container_of() is in practice a noop. However if a member
      is added to struct zynq_gpio in front of struct gpio_chip,
      things will break. Using proper container_of() avoids this
      problem.

      Semantically this is a noop, the compiler will optimize it away,
      but syntactically it makes me happier.

      Also replace some explicit container_of() calls with the helper
      function.

      gpio: pl061: detail IRQ trigger handling

      I couldn't follow this code flow. Make it dirt simple to figure
      out what is going on and get proper debug prints. Warn if we
      set up an IRQ without any trigger. Should make no semantic
      difference.

      pinctrl: imx25: ensure that a pin with id i is at position i in the info 
array

      The code in pinctrl-imx.c only works correctly if in the
      imx_pinctrl_soc_info passed to imx_pinctrl_probe we have:

        info->pins[i].number = i
        conf_reg(info->pins[i]) = 4 * i

      (which conf_reg(pin) being the offset of the pin's configuration
      register).

      When the imx25 specific part was introduced in b4a87c9b966f ("pinctrl:
      pinctrl-imx: add imx25 pinctrl driver") we had:

        info->pins[i].number = i + 1
        conf_reg(info->pins[i]) = 4 * i

      . Commit 34027ca2bbc6 ("pinctrl: imx25: fix numbering for pins") tried
      to fix that but made the situation:

        info->pins[i-1].number = i
        conf_reg(info->pins[i-1]) = 4 * i

      which is hardly better but fixed the error seen back then.

      So insert another reserved entry in the array to finally yield:

        info->pins[i].number = i
        conf_reg(info->pins[i]) = 4 * i

      The comment for PG14 mux setting 3 already correctly states that this

      Note that we use "pwm" rather then "pwm1" to be consistent with pwm0
      where the mux setting is also simply called "pwm" and to be consistent
      with sun4i/sun7i which do the same.

      This is because when using function graph tracer, if the traced
      function return value is in multi regs ([x0-x7]), return_to_handler
      may corrupt them. So in return_to_handler, the parameter regs should
      be protected properly.

      The difference between PINMUX_IPSR_MSEL() and PINMUX_IPSR_MODSEL_DATA()
      are FN_xxx order, and PINMUX_IPSR_MSEL() is used only from r8a7778.

      When using serial port SCIFB1_B, transmit works, but nothing is

      Receive fails because the SCIFB1_SCK_B settings configure the wrong
      value for the sel_scifb1 field in the Module Select Register (MOD_SEL),
      due to an ambiguity in the R-Car M2-W and M2-N datasheets.

      MIPS: BPF: Fix load delay slots.

      The entire bpf_jit_asm.S is written in noreorder mode because "we know
      better" according to a comment.  This also prevented the assembler from
      throwing in the required NOPs for MIPS I processors which have no
      load-use interlock, thus the load's consumer might end up using the
      old value of the register from prior to the load.

      Fixed by putting the assembler in reorder mode for just the affected
      load instructions.  This is not enough for gas to actually try to be
      clever by looking at the next instruction and inserting a nop only
      when needed but as the comment said "we know better", so getting gas
      to unconditionally emit a NOP is just right in this case and prevents
      adding further ifdefery.

      user-space, so in that case, just return an error.

      x86/mm: Set NX on gap between __ex_table and rodata

      Unused space between the end of __ex_table and the start of
      rodata can be left W+x in the kernel page tables.  Extend the
      setting of the NX bit to cover this gap by starting from
      text_end rather than rodata_start.

      x86/kexec: Fix kexec crash in syscall kexec_file_load()

      The original bug is a page fault crash that sometimes happens
      on big machines when preparing ELF headers:

          BUG: unable to handle kernel paging request at ffffc90613fc9000
          IP: [<ffffffff8103d645>] 
prepare_elf64_ram_headers_callback+0x165/0x260

      The bug is caused by us under-counting the number of memory ranges
      and subsequently not allocating enough ELF header space for them.
      The bug is typically masked on smaller systems, because the ELF header
      allocation is rounded up to the next page.

      This patch modifies the code in fill_up_crash_elf_data() by using
      walk_system_ram_res() instead of walk_system_ram_range() to correctly
      count the max number of crash memory ranges. That's because the
      walk_system_ram_range() filters out small memory regions that
      reside in the same page, but walk_system_ram_res() does not.

      Here's how I found the bug:

      After tracing prepare_elf64_headers() and 
prepare_elf64_ram_headers_callback(),
      the code uses walk_system_ram_res() to fill-in crash memory regions 
information
      to the program header, so it counts those small memory regions that
      reside in a page area.

      But, when the kernel was using walk_system_ram_range() in
      fill_up_crash_elf_data() to count the number of crash memory regions,
      it filters out small regions.

      I printed those small memory regions, for example:

        kexec: Get nr_ram ranges. vaddr=0xffff880077592258 paddr=0x77592258, 
sz=0xdc0

      Based on the code in walk_system_ram_range(), this memory region
      will be filtered out:

        pfn = (0x77592258 + 0x1000 - 1) >> 12 = 0x77593
        end_pfn = (0x77592258 + 0xfc0 -1 + 1) >> 12 = 0x77593
        end_pfn - pfn = 0x77593 - 0x77593 = 0  <=== if (end_pfn > pfn) is FALSE

      So, the max_nr_ranges that's counted by the kernel doesn't include
      small memory regions - causing us to under-allocate the required space.
      That causes the page fault crash that happens in a later code path
      when preparing ELF headers.

      This bug is not easy to reproduce on small machines that have few
      CPUs, because the allocated page aligned ELF buffer has more free
      space to cover those small memory regions' PT_LOAD headers.

      clk: ti: dflt: fix enable_reg validity check

      The default clock enabling functions for TI clocks -
      omap2_dflt_clk_enable() and omap2_dflt_clk_disable() perform a
      NULL check for the enable_reg field of the clk_hw_omap structure.
      This enable_reg field however is merely a combination of the index
      of the master IP module, and the offset from the master IP module's
      base address. A value of 0 is perfectly valid, and the current error
      checking will fail in these cases. The issue was found when trying
      to enable the iva2_ck clock on OMAP3 platforms.

      So, switch the check to use IS_ERR. This correction is similar to the
      logic used in commit c807dbedb5e5 ("clk: ti: fix ti_clk_get_reg_addr
      error handling").

      drm/dp/mst: make sure mst_primary mstb is valid in work function

      we validate the mstb structs in the work function, and doing
      that takes a reference. So we should never get here with the
      work function running using the mstb device, only if the work
      function hasn't run yet or is running for another mstb.

      So we don't need to sync the work here, this was causing
      lockdep spew as below.

      drm/dp/mst: split connector registration into two parts (v2)

      In order to cache the EDID properly for tiled displays, we
      need to retrieve it before we register the connector with
      userspace, otherwise userspace can call get resources
      and try and get the edid before we've even cached it.

      This fixes some problems when hotplugging mst monitors,
      with X/mutter running. As mutter seems to get 0 modes
      for one of the monitors in the tile.

      v2: fix warning in radeon
      handle tile setting in cached path rather than
      get edid path.

      drm/dp/mst: fixup handling hotplug on port removal.

      output ports should always have a connector, unless
      in the rare case connector allocation fails in the
      driver.

      In this case we only need to teardown the pdt,
      and free the struct, and there is no need to
      send a hotplug msg.

      In the case were we add the port to the destroy
      list we need to send a hotplug if we destroy
      any connectors, so userspace knows to reprobe
      stuff.

      this patch also handles port->connector allocation
      failing which should be a rare event, but makes
      the code consistent.

      [SMB3] Do not fall back to SMBWriteX in set_file_size error cases

      The error paths in set_file_size for cifs and smb3 are incorrect.

      In the unlikely event that a server did not support set file info
      of the file size, the code incorrectly falls back to trying SMBWriteX
      (note that only the original core SMB Write, used for example by DOS,
      can set the file size this way - this actually  does not work for the more
      recent SMBWriteX).  The idea was since the old DOS SMB Write could set
      the file size if you write zero bytes at that offset then use that if
      server rejects the normal set file info call.

      Fortunately the SMBWriteX will never be sent on the wire (except when
      file size is zero) since the length and offset fields were reversed
      in the two places in this function that call SMBWriteX causing
      the fall back path to return an error. It is also important to never call
      an SMB request from an SMB2/sMB3 session (which theoretically would
      be possible, and can cause a brief session drop, although the client
      recovers) so this should be fixed.  In practice this path does not happen
      with modern servers but the error fall back to SMBWriteX is clearly wrong.

      Removing the calls to SMBWriteX in the error paths in cifs_set_file_size

      Pull power management and ACPI fixes from Rafael Wysocki:
       "These are fixes mostly, for a few changes made in this cycle (the
        intel_idle driver, the OPP library, the ACPI EC driver, turbostat) and
        for some issues that have just been discovered (ACPI PCI IRQ
        management, PCI power management documentation, turbostat), with a
        couple of cleanups on top of them.

        Specifics:

         - intel_idle driver fixup for the recently added Skylake chips
           support (Len Brown).

         - Operating Performance Points (OPP) library fix related to the
           recently added support for new DT bindings and a fix for a typo in
           a comment (Viresh Kumar, Stephen Boyd).

         - ACPI EC driver fix for a recently introduced memory leak in an
           error code path (Lv Zheng).

         - ACPI PCI IRQ management fix for the issue where an ISA IRQ is
           shared with a PCI device which requires it to be configured in a
           different way and may cause an interrupt storm to happen as a
           result with an extra ACPI SCI IRQ handling simplification on top of
           it (Jiang Liu).

         - Update of the PCI power management documentation that became
           outdated and started to actively confuse the readers to make it
           actually reflect the code (Rafael J Wysocki).

         - turbostat fixes including an IVB Xeon regression fix (related to
           the --debug command line option), Skylake adjustment for the TSC
           running at a frequency that doesn't match the base one exactly, and
           a Knights Landing quirk to account for the fact that it only
           updates APERF and MPERF every 1024 clock cycles plus bumping up the
           turbostat version number (Len Brown, Hubert Chrzaniuk)"

      memcg: make mem_cgroup_read_stat() unsigned

      mem_cgroup_read_stat() returns a page count by summing per cpu page
      counters.  The summing is racy wrt.  updates, so a transient negative
      sum is possible.  Callers don't want negative values:

       - mem_cgroup_wb_stats() doesn't want negative nr_dirty or nr_writeback.
         This could confuse dirty throttling.

       - oom reports and memory.stat shouldn't show confusing negative usage.

       - tree_usage() already avoids negatives.

      Avoid returning negative page counts from mem_cgroup_read_stat() and
      convert it to unsigned.

      memcg: fix dirty page migration

      The problem starts with a file backed dirty page which is charged to a
      memcg.  Then page migration is used to move oldpage to newpage.

      Migration:
       - copies the oldpage's data to newpage
       - clears oldpage.PG_dirty
       - sets newpage.PG_dirty
       - uncharges oldpage from memcg
       - charges newpage to memcg

      Clearing oldpage.PG_dirty decrements the charged memcg's dirty page
      count.

      However, because newpage is not yet charged, setting newpage.PG_dirty
      does not increment the memcg's dirty page count.  After migration
      completes newpage.PG_dirty is eventually cleared, often in
      account_page_cleaned().  At this time newpage is charged to a memcg so
      the memcg's dirty page count is decremented which causes underflow
      because the count was not previously incremented by migration.  This
      underflow causes balance_dirty_pages() to see a very large unsigned
      number of dirty memcg pages which leads to aggressive throttling of
      buffered writes by processes in non root memcg.

      This issue:
       - can harm performance of non root memcg buffered writes.
       - can report too small (even negative) values in
         memory.stat[(total_)dirty] counters of all memcg, including the root.

      To avoid polluting migrate.c with #ifdef CONFIG_MEMCG checks, introduce
      page_memcg() and set_page_memcg() helpers.

      Test:
          0) setup and enter limited memcg
          mkdir /sys/fs/cgroup/test
          echo 1G > /sys/fs/cgroup/test/memory.limit_in_bytes
          echo $$ > /sys/fs/cgroup/test/cgroup.procs

          1) buffered writes baseline
          dd if=/dev/zero of=/data/tmp/foo bs=1M count=1k
          sync
          grep ^dirty /sys/fs/cgroup/test/memory.stat

          2) buffered writes with compaction antagonist to induce migration
          yes 1 > /proc/sys/vm/compact_memory &
          rm -rf /data/tmp/foo
          dd if=/dev/zero of=/data/tmp/foo bs=1M count=1k
          kill %
          sync
          grep ^dirty /sys/fs/cgroup/test/memory.stat

          3) buffered writes without antagonist, should match baseline
          rm -rf /data/tmp/foo
          dd if=/dev/zero of=/data/tmp/foo bs=1M count=1k
          sync
          grep ^dirty /sys/fs/cgroup/test/memory.stat

                             (speed, dirty residue)
                   unpatched                       patched
          1) 841 MB/s 0 dirty pages          886 MB/s 0 dirty pages

          3) 114 MB/s -33427456 dirty pages  891 MB/s 0 dirty pages

          Notice that unpatched baseline performance (1) fell after
          migration (3): 841 -> 114 MB/s.  In the patched kernel, post
          migration performance matches baseline.

      mm: hugetlbfs: skip shared VMAs when unmapping private pages to satisfy a 
fault

      SunDong reported the following on

        https://bugzilla.kernel.org/show_bug.cgi?id=103841

        I think I find a linux bug, I have the test cases is constructed. I
        can stable recurring problems in fedora22(4.0.4) kernel version,
        arch for x86_64.  I construct transparent huge page, when the parent
        and child process with MAP_SHARE, MAP_PRIVATE way to access the same
        huge page area, it has the opportunity to lead to huge page copy on
        write failure, and then it will munmap the child corresponding mmap
        area, but then the child mmap area with VM_MAYSHARE attributes, child
        process munmap this area can trigger VM_BUG_ON in set_vma_resv_flags
        functions (vma - > vm_flags & VM_MAYSHARE).

      There were a number of problems with the report (e.g.  it's hugetlbfs that
      triggers this, not transparent huge pages) but it was fundamentally
      correct in that a VM_BUG_ON in set_vma_resv_flags() can be triggered that
      looks like this

         vma ffff8804651fd0d0 start 00007fc474e00000 end 00007fc475e00000
         next ffff8804651fd018 prev ffff8804651fd188 mm ffff88046b1b1800
         prot 8000000000000027 anon_vma           (null) vm_ops ffffffff8182a7a0
         pgoff 0 file ffff88106bdb9800 private_data           (null)
         flags: 
0x84400fb(read|write|shared|mayread|maywrite|mayexec|mayshare|dontexpand|hugetlb)
         ------------
         kernel BUG at mm/hugetlb.c:462!
         SMP
         Modules linked in: xt_pkttype xt_LOG xt_limit [..]
         CPU: 38 PID: 26839 Comm: map Not tainted 4.0.4-default #1
         Hardware name: Dell Inc. PowerEdge R810/0TT6JF, BIOS 2.7.4 04/26/2012
         set_vma_resv_flags+0x2d/0x30

      The VM_BUG_ON is correct because private and shared mappings have
      different reservation accounting but the warning clearly shows that the
      VMA is shared.

      When a private COW fails to allocate a new page then only the process
      that created the VMA gets the page -- all the children unmap the page.
      If the children access that data in the future then they get killed.

      The problem is that the same file is mapped shared and private.  During
      the COW, the allocation fails, the VMAs are traversed to unmap the other
      private pages but a shared VMA is found and the bug is triggered.  This
      patch identifies such VMAs and skips them.

      mm/slab: fix unexpected index mapping result of kmalloc_size(INDEX_NODE+1)

      Commit description is copied from the original post of this bug:

        http://comments.gmane.org/gmane.linux.kernel.mm/135349

      Kernels after v3.9 use kmalloc_size(INDEX_NODE + 1) to get the next
      larger cache size than the size index INDEX_NODE mapping.  In kernels
      3.9 and earlier we used malloc_sizes[INDEX_L3 + 1].cs_size.

      However, sometimes we can't get the right output we expected via
      kmalloc_size(INDEX_NODE + 1), causing a BUG().

      The mapping table in the latest kernel is like:
          index = {0,   1,  2 ,  3,  4,   5,   6,   n}
           size = {0,   96, 192, 8, 16,  32,  64,   2^n}
      The mapping table before 3.10 is like this:
          index = {0 , 1 , 2,   3,  4 ,  5 ,  6,   n}
          size  = {32, 64, 96, 128, 192, 256, 512, 2^(n+3)}

      The problem on my mips64 machine is as follows:

      (1) When configured DEBUG_SLAB && DEBUG_PAGEALLOC && DEBUG_LOCK_ALLOC
          && DEBUG_SPINLOCK, the sizeof(struct kmem_cache_node) will be "150",
          and the macro INDEX_NODE turns out to be "2": #define INDEX_NODE
          kmalloc_index(sizeof(struct kmem_cache_node))

      (2) Then the result of kmalloc_size(INDEX_NODE + 1) is 8.

      (3) Then "if(size >= kmalloc_size(INDEX_NODE + 1)" will lead to "size
          = PAGE_SIZE".

      (4) Then "if ((size >= (PAGE_SIZE >> 3))" test will be satisfied and
          "flags |= CFLGS_OFF_SLAB" will be covered.

      (5) if (flags & CFLGS_OFF_SLAB)" test will be satisfied and will go to
          "cachep->slabp_cache = kmalloc_slab(slab_size, 0u)", and the result
          here may be NULL while kernel bootup.

      (6) Finally,"BUG_ON(ZERO_OR_NULL_PTR(cachep->slabp_cache));" causes the
          BUG info as the following shows (may be only mips64 has this problem):

      This patch fixes the problem of kmalloc_size(INDEX_NODE + 1) and removes
      the BUG by adding 'size >= 256' check to guarantee that all necessary
      small sized slabs are initialized regardless sequence of slab size in
      mapping table.

      userfaultfd: remove kernel header include from uapi header

      As include/uapi/linux/userfaultfd.h is a user visible header file, it
      should not include kernel-exclusive header files.

      So trying to build the userfaultfd test program from the selftests
      directory fails, since it contains a reference to linux/compiler.h.  As
      it turns out, that header is not really needed there, so we can simply
      remove it to fix that issue.

      Nikolay Aleksandrov says:

      ====================
      bridge: vlan: cleanups & fixes

      This is the first follow-up set, patch 01 reduces the default rhashtable
      size and the number of locks that can be allocated. Patch 02 and 04 fix
      possible null pointer dereferences due to the new ordering and
      initialization on port add/del, and patch 03 moves the "pvid" member in
      the net_bridge_vlan_group struct in order to simplify code (similar to how
      it was with the older struct). Patch 05 fixes adding a vlan on a port 
which
      is pvid and doesn't have a global context yet.
      Please review carefully, I think this is the first use of rhashtable's
      "locks_mul" member in the tree and I'd like to make sure it's correct.
      Another thing that needs special attention is the nbp_vlan_flush() move
      after the rx_handler unregister.

      bridge: vlan: don't pass flags when creating context only

      We should not pass the original flags when creating a context vlan only
      because they may contain some flags that change behaviour in the bridge.
      The new global context should be with minimal set of flags, so pass 0
      and let br_vlan_add() set the master flag only.

      bridge: vlan: fix possible null ptr derefs on port init and deinit

      When a new port is being added we need to make vlgrp available after
      rhashtable has been initialized and when removing a port we need to
      flush the vlans and free the resources after we're sure noone can use
      the port, i.e. after it's removed from the port list and synchronize_rcu
      is executed.

      bridge: vlan: move pvid inside net_bridge_vlan_group

      One obvious way to converge more code (which was also used by the
      previous vlan code) is to move pvid inside net_bridge_vlan_group. This
      allows us to simplify some and remove other port-specific functions.
      Also gives us the ability to simply pass the vlan group and use all of the
      contained information.

      bridge: vlan: fix possible null vlgrp deref while registering new port

      While a new port is being initialized the rx_handler gets set, but the
      vlans get initialized later in br_add_if() and in that window if we
      receive a frame with a link-local address we can try to dereference
      p->vlgrp in:
      br_handle_frame() -> br_handle_local_finish() -> br_should_learn()

      bridge: vlan: adjust rhashtable initial size and hash locks size

      As Stephen pointed out the default initial size is more than we need, so
      let's start small (4 elements, thus nelem_hint = 3). Also limit the hash
      locks to the number of CPUs as we don't need any write-side scaling and
      this looks like the minimum.

      Currently, BG2Q shares a compatible with BG2. This is incorrect, since
      BG2 and BG2Q use different USB PLL dividers. In reality, BG2Q shares a

      scsi_dh: Use the correct module name when loading device handler

      This fixes a bug in recent kernels which results in failure to boot
      on systems that have multipath SCSI disks.  I observed this failure
      on a POWER8 server where all the disks are multipath SCSI disks.
      The symptoms are several messages like this on the console:

      [    3.018700] device-mapper: table: 253:0: multipath: error attaching 
hardware handler
      [    3.018828] device-mapper: ioctl: error adding target to table

      and the system does not find its disks, and therefore fails to boot.

      Bisection revealed that the bug was introduced in commit 566079c849cf,
      "dm-mpath, scsi_dh: request scsi_dh modules in scsi_dh, not dm-mpath".
      The specific reason for the failure is that where we previously loaded
      the "scsi_dh_alua" module, we are now trying to load the "alua" module,
      which doesn't exist.

      To fix this, we change the request_module call in scsi_dh_lookup()
      to prepend "scsi_dh_" to the name, just like the old code in
      drivers/md/dm-mpath.c:parse_hw_handler() used to do.

      [jejb: also fixes issue spotted by Sasha Levin that formatting
      characters could be passed in via sysfs and cause issues with
      request_module()]

      arm64: Fix THP protection change logic

      6910fa1 ("arm64: enable PTE type bit in the mask for pte_modify") fixes
      a problem whereby a large block of PROT_NONE mapped memory is
      incorrectly mapped as block descriptors when mprotect is called.

      Unfortunately, a subtle bug was introduced by this fix to the THP logic.

      If one mmaps a large block of memory, then faults it such that it is
      collapsed into THPs; resulting calls to mprotect on this area of memory
      will lead to incorrect table descriptors being written instead of block
      descriptors. This is because pmd_modify calls pte_modify which is now
      allowed to modify the type of the page table entry.

      This patch reverts commit 6910fa16dbe142f6a0fd0fd7c249f9883ff7fc8a, and
      fixes the problem it was trying to address by adjusting PAGE_NONE to
      represent a table entry. Thus no change in pte type is required when
      moving from PROT_NONE to a different protection.

pte_modify")

      net: sfc: avoid using timespec

      The sfc driver internally uses a time format based on 32-bit (unsigned)
      seconds and 32-bit nanoseconds. This means it will overflow in 2106,
      but the value we pass into it is a signed 32-bit tv_sec that already
      overflows in 2038 to a negative value.

      This patch changes the logic to use the lower 32 bits of the timespec64
      tv_sec in efx_ptp_ns_to_s_ns, which will have the correct value beyond 
the overflow.
      While this does not change any of the register values, it lets us
      keep using the driver after we deprecate the use of the timespec type
      in the kernel.

      In the efx_ptp_process_times function, the change to use timespec64
      is similar, in that the tv_sec portion is ignored anyway and we only
      care about the nanosecond portion that remains unchanged.

      ntp/pps: use y2038 safe types in pps_event_time

      The pps_event_time uses two 'timespec' structures internally, which
      suffer from the y2038 problem. The uses of this structure are
      fairly self-contained in the pps code, so this replaces them all at
      once.

      Unfortunately, this includes the sfc ethernet driver aside from the
      pps subsystem, so we change that one as well. Both touch the
      same data structure, and there probably is no good way to split
      the patch into smaller units.

      ntp: use timespec64 in sync_cmos_clock

      The sync_cmos_clock has one use of struct timespec, which we want to
      eventually replace with timespec64 or similar in the kernel. There
      is no way this one can overflow, but the conversion to timespec64
      is trivial and has no other dependencies.

      ntp/pps: replace getnstime_raw_and_real with 64-bit version

      There is exactly one caller of getnstime_raw_and_real in the kernel,
      which is the pps_get_ts function. This changes the caller and
      the implementation to work on timespec64 types rather than timespec,
      to avoid the time_t overflow on 32-bit architectures.

      For consistency with the other new functions (ktime_get_seconds,
      ktime_get_real_*, ...), I'm renaming the function to
      ktime_get_raw_and_real_ts64.

      We still need to convert from the internal 64-bit type to 32 bit
      types in the caller, but this conversion is now pushed out from
      getnstime_raw_and_real to pps_get_ts. A follow-up patch changes
      the remaining pps code to completely avoid the conversion.

      ntp/pps: use timespec64 for hardpps()

      There is only one user of the hardpps function in the kernel, so
      it makes sense to atomically change it over to using 64-bit
      timestamps for y2038 safety. In the hardpps implementation,
      we also need to change the pps_normtime structure, which is
      similar to struct timespec and also requires a 64-bit
      seconds portion.

      This introduces two temporary variables in pps_kc_event() to
      do the conversion, they will be removed again in the next step,
      which seemed preferable to having a larger patch changing it
      all at the same time.

      Use WARN_ON_ONCE for missing X86_FEATURE_NRIPS

      The cpu feature flags are not ever going to change, so warning
      everytime can cause a lot of kernel log spam
      (in our case more than 10GB/hour).

      The warning seems to only occur when nested virtualization is
      enabled, so it's probably triggered by a KVM bug.  This is a
      sensible and safe change anyway, and the KVM bug fix might not
      be suitable for stable releases anyway.

      perf report: Fix a bug on "--call-graph none" option

      The patch f9db0d0f1b2c ("perf callchain: Allow disabling call graphs
      per event") added an ability to enable/disable callchain recording per
      event.  But it had a problem when the enablement setting is changed at
      'perf report' time using -g/--call-graph option.

      For example, the following scenario will get a segfault.

        $ perf record -ag sleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.500 MB perf.data (2555 samples) ]

        $ perf report -g none
        perf: Segmentation fault
        -------- backtrace --------
        perf[0x53a98a]
        /usr/lib/libc.so.6(+0x335af)[0x7f4e91df95af]

      This is because callchain_param.sort() callback was not set but it
      tried to call the function as it had the PERF_SAMPLE_CALLCHAIN bit.

      perf top: Fix unresolved comm when -s comm is used

      The perf top uses 'dso,symbol' sort keys by default so it overlooked a
      problem in task's comm resolving.  When the sort key contains 'comm',
      some task's comm is not shown properly.  This is because the
      perf_top__mmap_read_idx() checks the cpumode value improperly.

      The cpumode value of non-sample events are 0 (PERF_RECORD_MISC_CPUMODE_
      UNKNOWN) so the events will be ignored by the switch statement.  This 
patch
      allows it for non-sample events.

      perf record: Allocate area for sample_id_hdr in a synthesized comm event

      A previous patch added a synthesized comm event for forked child process
      but it missed that the event should contain area for sample_id_hdr at
      the end.  It worked by accident since the perf_event union contains
      bigger event structs like mmap_events.

      This patch fixes it by dynamically allocating event struct including
      those area like in perf_event__synthesize_thread_map().

      genirq: Introduce generic irq migration for cpu hotunplug

      ARM and ARM64 have almost identical code for migrating interrupts on
      cpu hotunplug. Provide a generic version which can be used by both.

      The new code addresses a shortcoming in the ARM[64] variants which
      fails to update the affinity change in some cases. The solution for
      this is to use the core function irq_do_set_affinity() instead of open
      coding it.

      The reason is that I forgot the IPv6 fragmentation here. Our MTU of
      lowpan interface is 1280 and skb->len should not above of that. If we
      reach a payload above 1280 in IPv6 header then we have a IPv6
      fragmentation above 802.15.4 6LoWPAN fragmentation. The type "u16" was
      fine, instead I added now a WARN_ON_ONCE if skb->len is above MTU which
      should never happen otherwise IPv6 on minimum MTU size is broken.

      fs/proc, core/debug: Don't expose absolute kernel addresses via wchan

      So the /proc/PID/stat 'wchan' field (the 30th field, which contains
      the absolute kernel address of the kernel function a task is blocked in)
      leaks absolute kernel addresses to unprivileged user-space:

              seq_put_decimal_ull(m, ' ', wchan);

      The absolute address might also leak via /proc/PID/wchan as well, if
      KALLSYMS is turned off or if the symbol lookup fails for some reason:

      static int proc_pid_wchan(struct seq_file *m, struct pid_namespace *ns,
                                struct pid *pid, struct task_struct *task)
      {
              unsigned long wchan;
              char symname[KSYM_NAME_LEN];

              wchan = get_wchan(task);

              if (lookup_symbol_name(wchan, symname) < 0) {
                      if (!ptrace_may_access(task, PTRACE_MODE_READ))
                              return 0;
                      seq_printf(m, "%lu", wchan);
              } else {
                      seq_printf(m, "%s", symname);
              }

              return 0;
      }

      This isn't ideal, because for example it trivially leaks the KASLR offset
      to any local attacker:

        fomalhaut:~> printf "%016lx\n" $(cat /proc/$$/stat | cut -d' ' -f35)
        ffffffff8123b380

      Most real-life uses of wchan are symbolic:

        ps -eo pid:10,tid:10,wchan:30,comm

      and procps uses /proc/PID/wchan, not the absolute address in 
/proc/PID/stat:

        triton:~/tip> strace -f ps -eo pid:10,tid:10,wchan:30,comm 2>&1 | grep 
wchan | tail -1
        open("/proc/30833/wchan", O_RDONLY)     = 6

      There's one compatibility quirk here: procps relies on whether the
      absolute value is non-zero - and we can provide that functionality
      by outputing "0" or "1" depending on whether the task is blocked
      (whether there's a wchan address).

      These days there appears to be very little legitimate reason
      user-space would be interested in  the absolute address. The
      absolute address is mostly historic: from the days when we
      didn't have kallsyms and user-space procps had to do the
      decoding itself via the System.map.

      So this patch sets all numeric output to "0" or "1" and keeps only
      symbolic output, in /proc/PID/wchan.

      ( The absolute sleep address can generally still be profiled via
        perf, by tasks with sufficient privileges. )

      arm64/efi: Fix boot crash by not padding between EFI_MEMORY_RUNTIME 
regions

      The new Properties Table feature introduced in UEFIv2.5 may
      split memory regions that cover PE/COFF memory images into
      separate code and data regions. Since these regions only differ
      in the type (runtime code vs runtime data) and the permission
      bits, but not in the memory type attributes (UC/WC/WT/WB), the
      spec does not require them to be aligned to 64 KB.

      Since the relative offset of PE/COFF .text and .data segments
      cannot be changed on the fly, this means that we can no longer
      pad out those regions to be mappable using 64 KB pages.
      Unfortunately, there is no annotation in the UEFI memory map
      that identifies data regions that were split off from a code
      region, so we must apply this logic to all adjacent runtime
      regions whose attributes only differ in the permission bits.

      So instead of rounding each memory region to 64 KB alignment at
      both ends, only round down regions that are not directly
      preceded by another runtime region with the same type
      attributes. Since the UEFI spec does not mandate that the memory
      map be sorted, this means we also need to sort it first.

      Note that this change will result in all EFI_MEMORY_RUNTIME
      regions whose start addresses are not aligned to the OS page
      size to be mapped with executable permissions (i.e., on kernels
      compiled with 64 KB pages). However, since these mappings are
      only active during the time that UEFI Runtime Services are being
      invoked, the window for abuse is rather small.

  Author: Matt Fleming <matt.fleming@xxxxxxxxx>

      x86/efi: Fix boot crash by mapping EFI memmap entries bottom-up at 
runtime, instead of top-down

      Beginning with UEFI v2.5 EFI_PROPERTIES_TABLE was introduced
      that signals that the firmware PE/COFF loader supports splitting
      code and data sections of PE/COFF images into separate EFI
      memory map entries. This allows the kernel to map those regions
      with strict memory protections, e.g. EFI_MEMORY_RO for code,
      EFI_MEMORY_XP for data, etc.

      Unfortunately, an unwritten requirement of this new feature is
      that the regions need to be mapped with the same offsets
      relative to each other as observed in the EFI memory map. If
      this is not done crashes like this may occur,

        BUG: unable to handle kernel paging request at fffffffefe6086dd
        IP: [<fffffffefe6086dd>] 0xfffffffefe6086dd
        Call Trace:
         [<ffffffff8104c90e>] efi_call+0x7e/0x100
         [<ffffffff81602091>] ? virt_efi_set_variable+0x61/0x90
         [<ffffffff8104c583>] efi_delete_dummy_variable+0x63/0x70
         [<ffffffff81f4e4aa>] efi_enter_virtual_mode+0x383/0x392

         [<ffffffff81f37495>] x86_64_start_reservations+0x2a/0x2c
         [<ffffffff81f37582>] x86_64_start_kernel+0xeb/0xef

      Here 0xfffffffefe6086dd refers to an address the firmware
      expects to be mapped but which the OS never claimed was mapped.
      The issue is that included in these regions are relative
      addresses to other regions which were emitted by the firmware
      toolchain before the "splitting" of sections occurred at
      runtime.

      Needless to say, we don't satisfy this unwritten requirement on
      x86_64 and instead map the EFI memory map entries in reverse
      order. The above crash is almost certainly triggerable with any
      kernel newer than v3.13 because that's when we rewrote the EFI
      runtime region mapping code, in commit d2f7cbe7b26a ("x86/efi:
      Runtime services virtual mapping"). For kernel versions before
      v3.13 things may work by pure luck depending on the
      fragmentation of the kernel virtual address space at the time we
      map the EFI regions.

      Instead of mapping the EFI memory map entries in reverse order,
      where entry N has a higher virtual address than entry N+1, map
      them in the same order as they appear in the EFI memory map to
      preserve this relative offset between regions.

      This patch has been kept as small as possible with the intention
      that it should be applied aggressively to stable and
      distribution kernels. It is very much a bugfix rather than
      support for a new feature, since when EFI_PROPERTIES_TABLE is
      enabled we must map things as outlined above to even boot - we
      have no way of asking the firmware not to split the code/data
      regions.

      In fact, this patch doesn't even make use of the more strict
      memory protections available in UEFI v2.5. That will come later.

      regulator: core: Handle probe deferral from DT when resolving supplies

      When resolving regulator-regulator supplies we ignore probe deferral
      returns from regulator_dev_lookup() (such as are generated for DT when
      we can see a supply is registered) and just fall back to the dummy
      regulator if there are full constraints (as is the case for DT).  This
      means that probe deferral is broken for DT systems, fix that by paying
      attention to -EPROBE_DEFER return codes like we do -ENODEV.

      A further patch will simplify this further, this is a minimal fix for
      the specific issue.

      Bluetooth: hci_intel: Cleanup the device probe code

      There is some unneeded code in "hci_intel" probing. First
      acpi_match_device() call is needless as driver/platform/acpi core code has
      already done the matching before calling the probe and the driver does not
      use the returned pointer to matching _HID other than checking is it NULL.

      Then tree wide grep for "hci_intel" doesn't reveal that there is any code
      registering this platform device so it looks this device is always backed
      with ACPI companion so also ACPI_HANDLE() test can be removed.

      ipvs: Don't protect ip_vs_addr_is_unicast with CONFIG_SYSCTL

      I arranged the code so that the compiler can remove the unecessary bits
      in ip_vs_leave when CONFIG_SYSCTL is unset, and removed an explicit
      CONFIG_SYSCTL.

      Unfortunately when rebasing my work on top of that of Alex Gartrell I
      missed the fact that the newly added function ip_vs_addr_is_unicast was
      surrounded by CONFIG_SYSCTL.

      So remove the now unnecessary CONFIG_SYSCTL guards around
      ip_vs_addr_is_unicast.  It is causing build failures today when
      CONFIG_SYSCTL is not selected and any self respecting compiler will
      notice that sysctl_cache_bypass is always false without CONFIG_SYSCTL
      and not include the logic from the function ip_vs_addr_is_unicast in
      the compiled code.

      dmaengine: pxa_dma: fix residue corner case

      A very tiny temporal window exists in the residue calculation where :
       - upon entering residue calculation, the transfer is ongoing
       - when reading the current transfer pointer, it just changed to
         the "finisher/linker" descriptor

      In this case, the residue returned is the whole transfer length instead
      of 0. Fix it.

      This appears almost in one extreme case, where the driver is used
      by older clients which inquire for residue in interrupt context, such
      as the smsc91x ethernet driver, in a tight loop :
        interrupt_handler()
          dmaengine_submit()
          do {
            dmaengine_tx_status()
          } while (residue > 0 || status != DMA_ERROR)

      cxl: fix leak of ctx->mapping when releasing kernel API contexts

      When a context is created via the kernel API, ctx->mapping is allocated
      within the kernel and thus needs to be freed when the context is freed.
      reclaim_ctx() attempts to do this for contexts with the ctx->kernelapi 
flag
      set, but afu_release() (which can be called from the kernel API through
      cxl_fd_release()) sets ctx->mapping to NULL before calling
      cxl_context_free() to free the context.

      Add a check to afu_release() so that the mappings in contexts created via
      the kernel API are left alone so reclaim_ctx() can free them.

      perf tools: By default use the most precise "cycles" hw counter available

      If the user doesn't specify any event, try the most precise "cycles"
      available, i.e. start by "cycles:ppp" and go on removing "p" till it
      works.

      E.g.

        $ perf record usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.017 MB perf.data (11 samples) ]
        $ perf evlist
        cycles:pp
        $ perf evlist -v
        cycles:pp: size: 112, { sample_period, sample_freq }: 4000, sample_type:
        IP|TID|TIME|PERIOD, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1,
        enable_on_exec: 1, task: 1, precise_ip: 2, sample_id_all: 1,
        exclude_guest: 1, mmap2: 1, comm_exec: 1
        $ grep 'model name' /proc/cpuinfo | head -1
        model name      : Intel(R) Core(TM) i7-3667U CPU @ 2.00GHz
        $

      When 'cycles' appears explicitely is specified this will not be tried,
      i.e. the user has full control of the level of precision to be used:

        $ perf record -e cycles usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.016 MB perf.data (9 samples) ]
        $ perf evlist
        cycles
        $ perf evlist -v
        cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type:
        IP|TID|TIME|PERIOD, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1,

      perf probe: Fix a segfault bug in debuginfo_cache

      perf probe --list will get a segfault if the first kprobe event is on a
      module and the second or latter one is on the kernel.

      e.g.
        ----
        # ./perf probe -q -m pcspkr pcspkr_event
        # ./perf probe -q vfs_read
        # ./perf probe -l
        Segmentation fault (core dumped)
        ----

      This is because the debuginfo_cache fails to handle NULL module name,
      which causes segfault on strcmp. (Note that strcmp("something", NULL)
      always causes segfault)

      To fix this debuginfo_cache__open always translates the NULL module name
      to "kernel" (this is correct, because NULL module name means opening the
      debuginfo for the kernel)

        ----
        # ./perf probe -l
          probe:pcspkr_event   (on pcspkr_event@drivers/input/misc/pcspkr.c

      This fixes the above issue as below.
      1. Get the relative address of the symbol in .text by using
         map->start.
      2. Adjust the address by adding the offset of .text section
         in the kernel module binary.

      With this fix, perf probe -l shows lines correctly.

      perf probe: Fix to remove dot suffix from second or latter events

      Fix to remove dot suffix (e.g. .const, .isra) from the second or latter
      events which has suffix numbers.

      Since the previous commit 35a23ff928b0 ("perf probe: Cut off the gcc
      optimization postfixes from function name") didn't care about the suffix
      numbered events, therefore we'll have an error when we add additional
      events on the same dot suffix functions.

      e.g.
        ----
        # ./perf probe -f -a get_sigframe.isra.2.constprop.3 \
         -a get_sigframe.isra.2.constprop.3
        Failed to write event: Invalid argument
          Error: Failed to add events.
        ----

      This fixes above issue as below:
        ----
        # ./perf probe -f -a get_sigframe.isra.2.constprop.3 \
         -a get_sigframe.isra.2.constprop.3
        Added new events:
          probe:get_sigframe   (on get_sigframe.isra.2.constprop.3)
          probe:get_sigframe_1 (on get_sigframe.isra.2.constprop.3)

        You can now use it in all perf tools, such as:

                perf record -e probe:get_sigframe_1 -aR sleep 1

      perf tools: Fix build break on powerpc due to sample_reg_masks

      The perf_regs.c file does not get built on Powerpc as CONFIG_PERF_REGS
      is false.  So the weak definition for 'sample_regs_masks' doesn't get
      picked up.

      Adding perf_regs.o to util/Build unconditionally, exposes a redefinition
      error for 'perf_reg_value()' function (due to the static inline version
      in util/perf_regs.h). So use #ifdef HAVE_PERF_REGS_SUPPORT' around that
      function.

      perf report: Amend documentation about max_stack and synthesized 
callchains

      The --max_stack option was added as an optimization to reduce processing 
time,
      so people specifying --max-stack might get a increased processing time if
      combined with synthesized callchains, but otherwise no real harm.

      A warning about setting both --max_stack and the synthesized callchains 
max
      depth seems like overkill.  Amend the documentation.

      x86/process: Add proper bound checks in 64bit get_wchan()

      Dmitry Vyukov reported the following using trinity and the memory
      error detector AddressSanitizer
      
(https://code.google.com/p/address-sanitizer/wiki/AddressSanitizerForKernel).

      [ 124.575597] ERROR: AddressSanitizer: heap-buffer-overflow on

      ./arch/x86/kernel/process_64.c:444

      The address checks in the 64bit implementation of get_wchan() are
      wrong in several ways:

       - The lower bound of the stack is not the start of the stack
         page. It's the start of the stack page plus sizeof (struct
         thread_info)

       - The upper bound must be:

             top_of_stack - TOP_OF_KERNEL_STACK_PADDING - 2 * sizeof(unsigned 
long).

         The 2 * sizeof(unsigned long) is required because the stack pointer
         points at the frame pointer. The layout on the stack is: ... IP FP
         ... IP FP. So we need to make sure that both IP and FP are in the
         bounds.

      Fix the bound checks and get rid of the mix of numeric constants, u64
      and unsigned long. Making all unsigned long allows us to use the same
      function for 32bit as well.

      Use READ_ONCE() when accessing the stack. This does not prevent a
      concurrent wakeup of the task and the stack changing, but at least it
      avoids TOCTOU.

      Also check task state at the end of the loop. Again that does not
      prevent concurrent changes, but it avoids walking for nothing.

      Add proper comments while at it.

      Calling strlen() no less than three times on entry is silly. Since
      we're formatting into a buffer with plenty of room, there's no chance
      of truncation, so snprintf() has actually returned the value we want,
      meaning we don't even have to call strlen once.

      x86/x2apic: Make stub functions available even if !CONFIG_X86_LOCAL_APIC

      Some CONFIG_X86_X2APIC functions, especially x2apic_enabled(), are not
      declared if !CONFIG_X86_LOCAL_APIC.  However, the same stubs that work
      for !CONFIG_X86_X2APIC are okay even if there is no local APIC support
      at all.

      Avoid the introduction of #ifdefs by moving the x2apic declarations
      completely outside the CONFIG_X86_LOCAL_APIC block.  (Unfortunately,
      diff generation messes up the actual change that this patch makes).
      There is no semantic change because CONFIG_X86_X2APIC depends on
      CONFIG_X86_LOCAL_APIC.

      workqueue: make sure delayed work run in local cpu

      My system keeps crashing with below message. vmstat_update() schedules a 
delayed
      work in current cpu and expects the work runs in the cpu.
      schedule_delayed_work() is expected to make delayed work run in local 
cpu. The
      problem is timer can be migrated with NO_HZ. __queue_work() queues work in
      timer handler, which could run in a different cpu other than where the 
delayed
      work is scheduled. The end result is the delayed work runs in different 
cpu.
      The patch makes __queue_delayed_work records local cpu earlier. Where the 
timer
      runs doesn't change where the work runs with the change.

      Initialize msg/shm IPC objects before doing ipc_addid()

      As reported by Dmitry Vyukov, we really shouldn't do ipc_addid() before
      having initialized the IPC object state.  Yes, we initialize the IPC
      object in a locked state, but with all the lockless RCU lookup work,
      that IPC object lock no longer means that the state cannot be seen.

      We already did this for the IPC semaphore code (see commit e8577d1f0329:
      "ipc/sem.c: fully initialize sem_array before making it visible") but we
      clearly forgot about msg and shm.

      RDS: Use per-bucket rw lock for bind hash-table

      One global lock protecting hash-tables with 1024 buckets isn't
      efficient and it shows up in a massive systems with truck
      loads of RDS sockets serving multiple databases. The
      perf data clearly highlights the contention on the rw
      lock in these massive workloads.

      When the contention gets worse, the code gets into a state where
      it decides to back off on the lock. So while it has disabled interrupts,
      it sits and backs off on this lock get. This causes the system to
      become sluggish and eventually all sorts of bad things happen.

      The simple fix is to move the lock into the hash bucket and
      use per-bucket lock to improve the scalability.

      RDS: make socket bind/release locking scheme simple and more efficient

      RDS bind and release locking scheme is very inefficient. It
      uses RCU for maintaining the bind hash-table which is great but
      it also needs to hold spinlock for [add/remove]_bound(). So
      overall usecase, the hash-table concurrent speedup doesn't pay off.
      In fact blocking nature of synchronize_rcu() makes the RDS
      socket shutdown too slow which hurts RDS performance since
      connection shutdown and re-connect happens quite often to
      maintain the RC part of the protocol.

      So we make the locking scheme simpler and more efficient by
      replacing spin_locks with reader/writer locks and getting rid
      off rcu for bind hash-table.

      In subsequent patch, we also covert the global lock with per-bucket
      lock to reduce the global lock contention.

      synchronize_rcu() slowing down un-necessarily the socket shutdown
      path. It is used just kfree() the ip addresses in rds_ib_remove_ipaddr()
      which is perfect usecase for kfree_rcu();

      So lets use that to gain some speedup.

      The CONFIG_MIPS_MT symbol can be selected by CONFIG_MIPS_VPE_LOADER in

      The MT-specific code in mips_cps_boot_vpes can safely be omitted from

      as it would be after the has_mt (Config3.MT) check failed at runtime.

      MIPS: CPS: Stop dangling delay slot from has_mt.

      The has_mt macro ended with a branch, leaving its callers with a delay
      slot that would be executed if Config3.MT is not set. However it would
      not be executed if Config3 (or earlier Config registers) don't exist
      which makes it somewhat inconsistent at best. Fill the delay slot in the

      MIPS: dma-default: Fix 32-bit fall back to GFP_DMA

      If there is a DMA zone (usually 24bit = 16MB I believe), but no DMA32
      zone, as is the case for some 32-bit kernels, then massage_gfp_flags()
      will cause DMA memory allocated for devices with a 32..63-bit
      coherent_dma_mask to fall back to using __GFP_DMA, even though there may
      only be 32-bits of physical address available anyway.

      Correct that case to compare against a mask the size of phys_addr_t
      instead of always using a 64-bit mask.

      drm/vmwgfx: Fix a command submission hang regression

      When we're out of command buffer space, we turn on the command buffer
      processed irq without re-checking for finished command buffers afterwards.
      This might lead to a missed irq and the command submission process waiting
      forever for space.

      Fix this by rerunning the command buffer submission handler whenever we're
      out of command space. This ensures both that we don't needlessly turn on
      the irq, and that if we decide to turn on the irq, we recheck for finished
      command buffers before going to sleep.

      i40evf: tweak init timing

      This patch tweaks the init timing of the driver just a little bit to
      increase stability on load/unload and SR-IOV enable/disable cycles.

      First, run the init_task loop a little quicker in order to reduce
      overall init time.

      Second, stagger the start of the init task based on the device's
      PCIe function ID. This lessens the impact on the firmware when a
      whole bunch of VFs are initialized simultaneously, e.g. enabling
      SR-IOV without the VF driver blacklisted. For single VFs assigned
      to VMs this will have no effect as the function ID will always be 0.

      This issue has been fixed in a recent refactor of the reset code, but

      reintroduce this issue or if we missed any cases.

      disabled. It was running when it didn't need to, and not clearing
      the ring->arm_wb state after it was set.  This caused Tx hangs
      to still occur occasionally when there really was no hang.
      Fix this by resetting the variable right after it was used.

      i40e: fixup padding issue in get_cee_dcb_cfg_v1_resp

      The struct i40e_aqc_get_cee_dcb_cfg_v1_resp was originally defined with
      word boundary layout issues, which most compilers deal with by silently
      adding padding, making the actual struct larger than designed.
      This patch adds an extra byte in fields reserved3 and reserved4 to 
directly
      acknowledge that padding.

      Because the struct doesn't actually change in size or layout, this doesn't
      constitute a change in the API.

      i40e: Fix a port VLAN configuration bug

      If a port VLAN is set for a given virtual function (VF) before the VF
      driver is loaded then a configuration error results in which the port
      VLAN is ignored when the VF driver is subsequently loaded.  This causes
      the VF's MAC/VLAN filters to not use the correct VLAN filter.  This
      patch ensures that the port VLAN filter is considered at the right time
      during configuration of the VF's MAC/VLAN filters.

      mac802154: check on len instead mac_len

      checking if the frame control field is available to dereference.
      We need to change it because I saw issues with af_packet raw sockets
      and the mrf24j40 which calls this functionality. The raw socket
      functionality doesn't set the mac_len but resets the skb_mac_header to
      skb->data which is still correct. The issue occur at mrf24j40 only,
      because the driver need to evaluate the fc fields.

      ieee802154: change mtu size behaviour

      This patch changes the mtu size of 802.15.4 interfaces. The current
      setting is the meaning of the maximum transport unit with mac header,
      which is 127 bytes according 802.15.4. The linux meaning of the mtu size
      field is the maximum payload of a mac frame. Like in ethernet, which is
      1500 bytes.

      We have dynamic length of mac frames in 802.15.4, this is why we assume
      the minimum header length which is hard_header_len. This contains fc and
      sequence fields. These can evaluated by driver layer without additional
      checks. We currently don't support to set the FCS from userspace, so we
      need to subtract this from mtu size as well.

      mac802154: add comments for llsec issues

      otherwise while capturing with wireshark the mac header shows secuirty
      fields but the payload is plaintext.

      A complete other issue is what doing with HardMAC drivers where the
      payload is always plaintext. I think we need a special handling then in
      userspace. We currently doesn't support any HardMAC transceivers, so we
      should fix the first issue for SoftMAC transceivers.

      drm/exynos: fix missed calling of drm_prime_gem_destroy()

      When obj->import_attach is existed, code calling drm_prime_gem_destroy()
      was removed from commit 67e93c808b48 ("drm/exynos: stop copying sg
      table"), and it's a fault.

      The drm_prime_gem_destroy() is cleanup function which GEM drivers need
      to call when they use drm_gem_prime_import() to import dma-bufs, so
      exynos-drm driver using drm_gem_prime_import() needs calling
      drm_prime_gem_destroy().

      Netfilter/IPVS updates for net-next

      The following pull request contains Netfilter/IPVS updates for net-next
      containing 90 patches from Eric Biederman.

      The main goal of this batch is to avoid recurrent lookups for the netns
      pointer, that happens over and over again in our Netfilter/IPVS code. The 
idea
      consists of passing netns pointer from the hook state to the relevant 
functions
      and objects where this may be needed.

      You can find more information on the IPVS updates from Simon Horman's 
commit
      merge message:

      c3456026adc0 ("Merge tag 'ipvs2-for-v4.4' of

      Exceptionally, this time, I'm not posting the patches again on netdev,

      ====================
      net: switchdev: use specific switchdev_obj_*

      This patchset changes switchdev add, del, dump operations from this:

          int     (*switchdev_port_obj_add)(struct net_device *dev,
                                            struct switchdev_obj *obj,
                                            struct switchdev_trans *trans);
          int     (*switchdev_port_obj_del)(struct net_device *dev,
                                            struct switchdev_obj *obj);
          int     (*switchdev_port_obj_dump)(struct net_device *dev,
                                            struct switchdev_obj *obj);

      to something similar to the notifier_call callback of a notifier_block:

          int     (*switchdev_port_obj_add)(struct net_device *dev,
                                            enum switchdev_obj_id id,
                                            const void *obj,
                                            struct switchdev_trans *trans);
          int     (*switchdev_port_obj_del)(struct net_device *dev,
                                            enum switchdev_obj_id id,
                                            const void *obj);
          int     (*switchdev_port_obj_dump)(struct net_device *dev,
                                             enum switchdev_obj_id id, void 
*obj,
                                             int (*cb)(void *obj));

      This allows the caller to pass and expect back a specific switchdev_obj_*
      structure (e.g. switchdev_obj_fdb) instead of the generic switchdev_obj 
one.

      This will simplify pushing the callback function down to the drivers.

      The first 3 patches get rid of the dev parameter of the dump callback, 
since it
      is not always neeeded (e.g. vlan_dump) and some drivers (such as DSA 
drivers)
      may not have easy access to it.

      Patches 4 and 5 implement the change in the switchdev operations and its 
users.

      Patch 6 extracts the inner switchdev_obj_* structures from switchdev_obj 
and
      removes this last one.

      v2: fix error spotted by kbuild (extra ';' inline 
switchdev_port_obj_dump).

      net: switchdev: remove dev from switchdev_obj cb

      The net_device associated to a dump operation does not have to be passed
      to the callback. switchdev stores it in a superset struct, if needed.

      Also some drivers (such as DSA drivers) may not have easy access to it.

      This will simplify pushing the callback function down to the drivers.

      net: switchdev: move dev in switchdev_fdb_dump

      The FDB dump callback requires the related net_device so move it to the
      struct switchdev_fdb_dump superset instead of using a callback param.

      With this done, it'll be simpler to change the dump function signature.

      testptp: Silence compiler warnings on ppc64

      This happens because __s64 is by default defined as "long" on ppc64,
      not as "long long". However, to fix these warnings, it's possible to
      define the __SANE_USERSPACE_TYPES__ so that __s64 gets defined to
      "long long" on ppc64, too.

      net/mlx4: Handle return codes in mlx4_qp_attach_common

      Both new_steering_entry() and existing_steering_entry() return values
      based on their success or failure, but currently they fall through
      silently.  This can make troubleshooting difficult, as we were unable
      to tell which one of these two functions returned errors or
      specifically what code was returned.  This patch remedies that
      situation by passing the return codes to err, which is returned by
      mlx4_qp_attach_common() itself.

      This also addresses a leak in the call to mlx4_bitmap_free() as well.

      Merge branch 'L3_master_device'

      David Ahern says:

      ====================
      net: L3 master device

      The VRF device is essentially a Layer 3 master device used to associate
      netdevices with a specific routing table and to influence FIB lookups
      via 'ip rules' and controlling the oif/iif used for the lookup.

      This series generalizes the VRF into L3 master device, l3mdev. Similar
      to switchdev it has a Kconfig option and separate set of operations
      in net_device allowing it to be completely compiled out if not wanted.
      The l3mdev methods rely on the 'master' aspect and use of
      netdev_master_upper_dev_get_rcu to retrieve the master device from a
      given netdevice if it is enslaved to an L3_MASTER.

      The VRF device is converted to use the l3mdev operations. At the end the
      vrf_ptr is no longer and removed, as are all direct references to VRF.
      The end result is a much simpler implementation for VRF.

      Thanks to Nikolay for suggestions (eg., use of the master linkage which
      is the key to making this work) and to Roopa, Andy and Shrijeet for
      early reviews.

      v3
      - added license header to l3mdev.c

      - export symbols in l3mdev.c for use with GPL modules

      - removed netdevice header from l3mdev.h (not needed) and fixed
        typo in comment

      v2
      - rebased to top of net-next
      - addressed Niks comments (checking master, removing extra lines, and
        flipping the order of patches 1 and 2)

      tcp: prepare fastopen code for upcoming listener changes

      While auditing TCP stack for upcoming 'lockless' listener changes,
      I found I had to change fastopen_init_queue() to properly init the object
      before publishing it.

      Otherwise an other cpu could try to lock the spinlock before it gets
      properly initialized.

      Instead of adding appropriate barriers, just remove dynamic memory
      allocations :
      - Structure is 28 bytes on 64bit arches. Using additional 8 bytes
        for holding a pointer seems overkill.
      - Two listeners can share same cache line and performance would suffer.

      If we really want to save few bytes, we would instead dynamically allocate
      whole struct request_sock_queue in the future.

      Earlier patch 6ae459bda tried to detect void ckecksum partial
      skb by comparing pull length to checksum offset. But it does
      not work for all cases since checksum-offset depends on
      updates to skb->data.

      Following patch fixes it by validating checksum start offset
      after skb-data pointer is updated. Negative value of checksum
      offset start means there is no need to checksum.

      net: Swap ordering of tests in ip_route_input_mc

      This patch just swaps the ordering of one of the conditional tests in
      ip_route_input_mc.  Specifically it swaps the testing for the source
      address to see if it is loopback, and the test to see if we allow a
      loopback source address.

      The reason for swapping these two tests is because it is much faster to
      test if an address is loopback than it is to dereference several pointers
      to get at the net structure to see if the use of loopback is allowed.

      The stack does consider the oif but a mismatch in rt6_device_match is not
      considered fatal because RT6_LOOKUP_F_IFACE is not set in the flags.

      netpoll: Drop budget parameter from NAPI polling call hierarchy

      For some reason we were carrying the budget value around between the
      various calls to napi->poll.  If for example one of the drivers called had
      a bug in which it returned a non-zero value for work this could result in
      the budget value becoming negative.

      Rather than carry around a value of budget that is 0 or less we can 
instead
      just loop through and pass 0 to each napi->poll call.  If any driver
      returns a value for work done that is non-zero then we can report that
      driver and continue rather than allowing a bad actor to make the budget
      value negative and pass that negative value to napi->poll.

      Note, the only actual change here is that instead of letting budget become
      negative we are keeping it at 0 regardless of the value returned for work
      since it should not be possible for the polling routine to do any actual
      work with a budget of 0.  So if the polling routine returns a non-0 value
      we are just reporting it and continuing with a budget of 0 rather than
      letting that work value be subtracted from the budget of 0.

      af_unix: return data from multiple SKBs on recv() with MSG_PEEK flag

      AF_UNIX sockets now return multiple skbs from recv() when MSG_PEEK flag
      is set.

      This is referenced in kernel bugzilla #12323 @
      https://bugzilla.kernel.org/show_bug.cgi?id=12323

      As described both in the BZ and lkml thread @
      http://lkml.org/lkml/2008/1/8/444 calling recv() with MSG_PEEK on an
      AF_UNIX socket only reads a single skb, where the desired effect is
      to return as much skb data has been queued, until hitting the recv
      buffer size (whichever comes first).

      The modified MSG_PEEK path will now move to the next skb in the tree
      and jump to the again: label, rather than following the natural loop
      structure. This requires duplicating some of the loop head actions.

      This was tested using the python socketpair python code attached to
      the bugzilla issue.

      bridge: vlan: add per-vlan struct and move to rhashtables

      This patch changes the bridge vlan implementation to use rhashtables
      instead of bitmaps. The main motivation behind this change is that we
      need extensible per-vlan structures (both per-port and global) so more
      advanced features can be introduced and the vlan support can be
      extended. I've tried to break this up but the moment net_port_vlans is
      changed and the whole API goes away, thus this is a larger patch.
      A few short goals of this patch are:
      - Extensible per-vlan structs stored in rhashtables and a sorted list
      - Keep user-visible behaviour (compressed vlans etc)
      - Keep fastpath ingress/egress logic the same (optimizations to come
        later)

      Here's a brief list of some of the new features we'd like to introduce:
      - per-vlan counters
      - vlan ingress/egress mapping
      - per-vlan igmp configuration
      - vlan priorities
      - avoid fdb entries replication (e.g. local fdb scaling issues)

      The structure is kept single for both global and per-port entries so to
      avoid code duplication where possible and also because we'll soon 
introduce
      "port0 / aka bridge as port" which should simplify things further
      (thanks to Vlad for the suggestion!).

      Now we have per-vlan global rhashtable (bridge-wide) and per-vlan port
      rhashtable, if an entry is added to a port it'll get a pointer to its
      global context so it can be quickly accessed later. There's also a
      sorted vlan list which is used for stable walks and some user-visible
      behaviour such as the vlan ranges, also for error paths.
      VLANs are stored in a "vlan group" which currently contains the
      rhashtable, sorted vlan list and the number of "real" vlan entries.
      A good side-effect of this change is that it resembles how hw keeps
      per-vlan data.
      One important note after this change is that if a VLAN is being looked up
      in the bridge's rhashtable for filtering purposes (or to check if it's an
      existing usable entry, not just a global context) then the new helper
      br_vlan_should_use() needs to be used if the vlan is found. In case the
      lookup is done only with a port's vlan group, then this check can be
      skipped.

      Things tested so far:
      - basic vlan ingress/egress
      - pvids
      - untagged vlans
      - undef CONFIG_BRIDGE_VLAN_FILTERING
      - adding/deleting vlans in different scenarios (with/without global ctx,
        while transmitting traffic, in ranges etc)
      - loading/removing the module while having/adding/deleting vlans
      - extracting bridge vlan information (user ABI), compressed requests
      - adding/deleting fdbs on vlans
      - bridge mac change, promisc mode
      - default pvid change
      - kmemleak ON during the whole time

      drm/amdgpu:  Restore LCD backlight level on resume

      Instead of only enabling the backlight (which seems to set it to max

      Merge branch 'mvneta_percpu_irq'

      Gregory CLEMENT says:

      ====================
      net: mvneta: Switch to per-CPU irq and make rxq_def useful

      As stated in the first version: "this patchset reworks the Marvell
      neta driver in order to really support its per-CPU interrupts, instead
      of faking them as SPI, and allow the use of any RX queue instead of
      the hardcoded RX queue 0 that we have currently."

      Following the review which has been done, Maxime started adding the
      CPU hotplug support. I continued his work a few weeks ago and here is
      the result.

      Since the 1st version the main change is this CPU hotplug support, in
      order to validate it I powered up and down the CPUs while performing
      iperf. I ran the tests during hours: the kernel didn't crash and the
      network interfaces were still usable. Of course it impacted the
      performance, but continuously power down and up the CPUs is not
      something we usually do.

      I also reorganized the series, the 3 first patches should go through
      the irq subsystem, whereas the 4 others should go to the network
      subsystem.

      However, there is a runtime dependency between the two parts. Patch 5
      depend on the patch 3 to be able to use the percpu irq.

      Thanks,

      Gregory

      PS: Thanks to Willy who gave me some pointers on how to deal with the
      NAPI.

      net: mvneta: Statically assign queues to CPUs

      Since the switch to per-CPU interrupts, we lost the ability to set which
      CPU was going to receive our RX interrupt, which was now only the CPU on
      which the mvneta_open function was run.

      We can now assign our queues to their respective CPUs, and make sure only
      this CPU is going to handle our traffic.

      This also paves the road to be able to change that at runtime, and later 
on
      to support RSS.

      net: mvneta: Allow different queues

      The mvneta driver allows to change the default RX queue trough the rxq_def
      kernel parameter.

      However, the current code doesn't allow to have any value but 0. It is
      actively checked for in the driver's probe because the drivers makes a
      number of assumption and takes a number of shortcuts in order to just use
      that RX queue.

      Remove these limitations in order to be able to specify any available
      queue.

      net: mvneta: Fix CPU_MAP registers initialisation

      The CPU_MAP register is duplicated for each CPUs at different addresses,
      each instance being at a different address.

      However, the code so far was using CONFIG_NR_CPUS to initialise the 
CPU_MAP
      registers for each registers, while the SoCs embed at most 4 CPUs.

      This is especially an issue with multi_v7_defconfig, where CONFIG_NR_CPUS
      is currently set to 16, resulting in writes to registers that are not
      CPU_MAP.

      blk-mq: fix deadlock when reading cpu_list

      CPU hotplug handling for blk-mq (blk_mq_queue_reinit) acquires
      all_q_mutex in blk_mq_queue_reinit_notify() and then removes sysfs
      entries by blk_mq_sysfs_unregister().  Removing sysfs entry needs to
      be blocked until the active reference of the kernfs_node to be zero.

      On the other hand, reading blk_mq_hw_sysfs_cpu sysfs entry (e.g.
      /sys/block/nullb0/mq/0/cpu_list) acquires all_q_mutex in
      blk_mq_hw_sysfs_cpus_show().

      If these happen at the same time, a deadlock can happen.  Because one
      can wait for the active reference to be zero with holding all_q_mutex,
      and the other tries to acquire all_q_mutex with holding the active
      reference.

      The reason that all_q_mutex is acquired in blk_mq_hw_sysfs_cpus_show()
      is to avoid reading an imcomplete hctx->cpumask.  Since reading sysfs
      entry for blk-mq needs to acquire q->sysfs_lock, we can avoid deadlock
      and reading an imcomplete hctx->cpumask by protecting q->sysfs_lock
      while hctx->cpumask is being updated.

      blk-mq: avoid inserting requests before establishing new mapping

      Notifier callbacks for CPU_ONLINE action can be run on the other CPU
      than the CPU which was just onlined.  So it is possible for the
      process running on the just onlined CPU to insert request and run
      hw queue before establishing new mapping which is done by
      blk_mq_queue_reinit_notify().

      This can cause a problem when the CPU has just been onlined first time
      since the request queue was initialized.  At this time ctx->index_hw
      for the CPU, which is the index in hctx->ctxs[] for this ctx, is still
      zero before blk_mq_queue_reinit_notify() is called by notifier
      callbacks for CPU_ONLINE action.

      For example, there is a single hw queue (hctx) and two CPU queues
      (ctx0 for CPU0, and ctx1 for CPU1).  Now CPU1 is just onlined and
      a request is inserted into ctx1->rq_list and set bit0 in pending
      bitmap as ctx1->index_hw is still zero.

      And then while running hw queue, flush_busy_ctxs() finds bit0 is set
      in pending bitmap and tries to retrieve requests in
      hctx->ctxs[0]->rq_list.  But htx->ctxs[0] is a pointer to ctx0, so the
      request in ctx1->rq_list is ignored.

      Fix it by ensuring that new mapping is established before onlined cpu
      starts running.

      blk-mq: fix q->mq_usage_counter access race

      CPU hotplug handling for blk-mq (blk_mq_queue_reinit) accesses
      q->mq_usage_counter while freezing all request queues in all_q_list.
      On the other hand, q->mq_usage_counter is deinitialized in
      blk_mq_free_queue() before deleting the queue from all_q_list.

      So if CPU hotplug event occurs in the window, percpu_ref_kill() is
      called with q->mq_usage_counter which has already been marked dead,
      and it triggers warning.  Fix it by deleting the queue from all_q_list

      blk-mq: fix sysfs registration/unregistration race

      There is a race between cpu hotplug handling and adding/deleting
      gendisk for blk-mq, where both are trying to register and unregister
      the same sysfs entries.

      null_add_dev
          --> blk_mq_init_queue
              --> blk_mq_init_allocated_queue
                  --> add to 'all_q_list' (*)
          --> add_disk
              --> blk_register_queue
                  --> blk_mq_register_disk (++)

      null_del_dev
          --> del_gendisk
              --> blk_unregister_queue
                  --> blk_mq_unregister_disk (--)
          --> blk_cleanup_queue
              --> blk_mq_free_queue
                  --> del from 'all_q_list' (*)

      blk_mq_queue_reinit
          --> blk_mq_sysfs_unregister (-)
          --> blk_mq_sysfs_register (+)

      While the request queue is added to 'all_q_list' (*),
      blk_mq_queue_reinit() can be called for the queue anytime by CPU
      hotplug callback.  But blk_mq_sysfs_unregister (-) and
      blk_mq_sysfs_register (+) in blk_mq_queue_reinit must not be called
      before blk_mq_register_disk (++) and after blk_mq_unregister_disk (--)
      is finished.  Because '/sys/block/*/mq/' is not exists.

      There has already been BLK_MQ_F_SYSFS_UP flag in hctx->flags which can
      be used to track these sysfs stuff, but it is only fixing this issue
      partially.

      In order to fix it completely, we just need per-queue flag instead of
      per-hctx flag with appropriate locking.  So this introduces
      q->mq_sysfs_init_done which is properly protected with all_q_mutex.

      Also, we need to ensure that blk_mq_map_swqueue() is called with
      all_q_mutex is held.  Since hctx->nr_ctx is reset temporarily and
      updated in blk_mq_map_swqueue(), so we should avoid
      blk_mq_register_hctx() seeing the temporary hctx->nr_ctx value
      in CPU hotplug handling or adding/deleting gendisk .

      blk-mq: avoid setting hctx->tags->cpumask before allocation

      When unmapped hw queue is remapped after CPU topology is changed,
      hctx->tags->cpumask has to be set after hctx->tags is setup in
      blk_mq_map_swqueue(), otherwise it causes null pointer dereference.

      svcrdma: handle rdma read with a non-zero initial page offset

      The server rdma_read_chunk_lcl() and rdma_read_chunk_frmr() functions
      were not taking into account the initial page_offset when determining
      the rdma read length.  This resulted in a read who's starting address
      and length exceeded the base/bounds of the frmr.

      The server gets an async error from the rdma device and kills the
      connection, and the client then reconnects and resends.  This repeats
      indefinitely, and the application hangs.

      Most work loads don't tickle this bug apparently, but one test hit it
      every time: building the linux kernel on a 16 core node with 'make -j
      16 O=/mnt/0' where /mnt/0 is a ramdisk mounted via NFSRDMA.

      This bug seems to only be tripped with devices having small fastreg page
      list depths.  I didn't see it with mlx4, for instance.

      cfg80211: allow changing station capabilities for unassociated stations

      Currently, cfg80211 rejects capability updates for existing entries
      and as a result it's impossible to update entries that were added
      unassociated, but that is necessary to go through the full station
      states from userspace, adding a station before authentication etc.

      Fix this by allowing updates to capabilities for stations that the
      driver (or mac80211) assigned unassociated state. Drivers setting
      the full station state support flag must use the new station type
      for proper operation.

      mac80211: allow writing TX PN in debugfs

      For certain tests, for example replay detection, it can be useful
      to be able to influence/set the PN used in outgoing packets. Make
      it possible to change the TX PN in debugfs.

      For now, this doesn't support TKIP since I haven't needed it, but
      there's no reason it couldn't be added if necessary.

      Note that this must be used very carefully: it could, for example,
      be used to make "valid replays" where the PN reuse happens on a
      different TID. This couldn't be done by an attacker since the TID
      is protected as part of the AAD.

      tear down aggregations on reconfiguration when we are not resuming.

      mac80211: Copy tx'ed beacons to monitor mode

      When debugging wireless powersave issues on the AP side it's quite helpful
      to see our own beacons that are transmitted by the hardware/driver. 
However,
      this is not that easy since beacons don't pass through the regular TX 
queues.

      Preferably drivers would call ieee80211_tx_status also for tx'ed beacons
      but that's not always possible. Hence, just send a copy of each beacon
      generated by ieee80211_beacon_get_tim to monitor devices when they are
      getting fetched by the driver.

      Also add a HW flag IEEE80211_HW_BEACON_TX_STATUS that can be used by
      drivers to indicate that they report TX status for beacons.

      s390/boot/decompression: disable floating point in decompressor

      my gcc 5.1 used an ldgr instruction with a register != 0,2,4,6 for
      spilling/filling into a floating point register in our decompressor.

      This will cause an AFP-register data exception as the decompressor
      did not setup the additional floating point registers via cr0.
      That causes a program check loop that looked like a hang with
      one "Uncompressing Linux... " message (directly booted via kvm)
      or a loop of "Uncompressing Linux... " messages (when booted via
      zipl boot loader).

      The offending code in my build was

         48e400:       e3 c0 af ff ff 71       lay     %r12,-1(%r10)
      -->48e406:       b3 c1 00 1c             ldgr    %f1,%r12
         48e40a:       ec 6c 01 22 02 7f       clij    %r6,2,12,0x48e64e

      but gcc could do spilling into an fpr at any function. We can
      simply disable floating point support at that early stage.

      clocksource/drivers/keystone: Fix bad NO_IRQ usage

      The current code assumes the 'irq_of_parse_and_map' will return NO_IRQ in 
case
      of failure. Unfortunately, the NO_IRQ is not consistent across the 
different
      architectures and we must not rely on it.

      NO_IRQ is equal to '-1' on ARM and 'irq_of_parse_and_map' returns '0' in 
case
      of an error. Hence, the latter won't be detected and will lead to a crash.

      Fix this by just checking 'irq' is different from zero.

      in vain because it is only being called in the inode allocation path
      and therefore nobody else can see the inode yet.

      changed CONFIG_SCSI_DH from tristate to bool.

      Our defconfigs have CONFIG_SCSI_DH=m, which the kconfig machinery warns
      us is invalid, but instead of converting it to =y it leaves it unset.
      This means we loose the CONFIG_SCSI_DH code and everything that depends
      on it.

      So convert the values in the defconfigs to =y.

      mmc: pxamci: fix card detect with slot-gpio API

      Move pxamci to mmc slot-gpio API to fix interrupt request.

      It fixes the case where the card detection is on a gpio expander, on I2C
      for example on zylonite board. In this case, the card detect netsted
      interrupt is called from a threaded interrupt. The request_irq() fails,
      because a hard irq cannot be a nested interrupt from a threaded
      interrupt (set __setup_irq()).

      This was tested on zylonite and mioa701 boards.

      mmc: sunxi: Fix clk-delay settings

      In recent allwinner kernel sources the mmc clk-delay settings have been
      slightly tweaked, and for sun9i they are completely different then what
      we are using.

      This commit brings us in sync with what allwinner does, fixing problems
      accessing sdcards on some A33 devices (and likely others).

      For pre sun9i hardware this makes the following changes:
      -At 400Khz change the sample delay from 7 to 0 (introduced in A31 sdk)
      -At 50 Mhz change the sample delay from 5 to 4 (introduced in A23 sdk)

      This also drops the clk-delay calculation for clocks > 50 MHz, we do
      not need this as we've: mmc->f_max = 50000000, and the delays in the
      old code were not correct (at 100 MHz the delay must be a multiple of 60,
      at 200 MHz a multiple of 120).

      mmc: core: Don't return an error for CD/WP GPIOs when GPIOLIB is unset

      When CONFIG_GPIOLIB is unset, its stubs will return -ENOSYS. That means
      when the mmc core parses DT for CD/WP GPIOs via mmc_of_parse(), -ENOSYS
      becomes propagated to the caller. Typically this means that the mmc host
      driver fails to probe.

      As the CD/WP GPIOs are already treated as optional, let's extend that to
      cover the case when CONFIG_GPIOLIB is unset.

      xfrm: Let the flowcache handle its size by default.

      The xfrm flowcache size is limited by the flowcache limit
      (4096 * number of online cpus) and the xfrm garbage collector
      threshold (2 * 32768), whatever is reached first. This means
      that we can hit the garbage collector limit only on systems
      with more than 16 cpus. On such systems we simply refuse
      new allocations if we reach the limit, so new flows are dropped.
      On syslems with 16 or less cpus, we hit the flowcache limit.
      In this case, we shrink the flow cache instead of refusing new
      flows.

      We increase the xfrm garbage collector threshold to INT_MAX
      to get the same behaviour, independent of the number of cpus.

      The xfrm garbage collector threshold can still be set below
      the flowcache limit to reduce the memory usage of the flowcache.

      irqchip/gicv3-its: Workaround for Cavium ThunderX errata 22375, 24313

      This implements two gicv3-its errata workarounds for ThunderX. Both
      with small impact affecting only ITS table allocation.

       erratum 22375: only alloc 8MB table size
       erratum 24313: ignore memory access type

      The fixes are in ITS initialization and basically ignore memory access
      type and table size provided by the TYPER and BASER registers.

      irqchip/gicv3-its: Add HW revision detection and configuration

      Some GIC revisions require an individual configuration to esp. add
      workarounds for HW bugs. This patch implements generic code to parse
      the hw revision provided by an IIDR register value and runs specific
      code if hw matches. A function is added that reads the IIDR registers
      for ITS (GITS_IIDR) and then goes through a list of init functions to
      be called for specific versions. Same could be done for GICV3
      (GICD_IIDR), but there are no users yet for it.

      The patch is needed to implement workarounds for HW errata in Cavium's
      ThunderX GICV3 ITS.

      No need to read the typer register in the loop. Values do not change.

      This patch is basically a prerequisite for a follow-on patch that adds
      errata code for Cavium ThunderX. It moves the calculation of the
      number of id entries to the beginning of the function close to other
      setup values that are needed to allocate the its table. Now we have a
      central location to modify the setup parameters and the errata code
      can be implemented in a single block.

      irqchip/gicv3: Workaround for Cavium ThunderX erratum 23154

      This patch implements Cavium ThunderX erratum 23154.

      The gicv3 of ThunderX requires a modified version for reading the IAR
      status to ensure data synchronization. Since this is in the fast-path
      and called with each interrupt, runtime patching is used using jump
      label patching for smallest overhead (no-op). This is the same
      technique as used for tracepoints.

      mwifiex: fix mwifiex_rdeeprom_read()

      There were several bugs here.

      1)  The done label was in the wrong place so we didn't copy any
          information out when there was no command given.

      2)  We were using PAGE_SIZE as the size of the buffer instead of
          "PAGE_SIZE - pos".

      3)  snprintf() returns the number of characters that would have been
          printed if there were enough space.  If there was not enough space
          (and we had fixed the memory corruption bug #2) then it would result
          in an information leak when we do simple_read_from_buffer().  I've
          changed it to use scnprintf() instead.

      I also removed the initialization at the start of the function, because
      I thought it made the code a little more clear.

      brcmfmac: Fix race condition bug when deleting p2p interface.

      When p2p device interface gets deleted by deinitialising discovery
      it will result in an event which removes the interface, but that is
      also done by delete p2p interface code. This results in race
      condition which sometimes results in lockup/crash. With this patch
      the delete device interface will wait for the event (with timeout)
      removing the possible race condition. Also on the stop device call
      from cfg80211 the deinitialisation of the discovery device should
      be avoided as it can result in a similar situation.

      brcmfmac: Fix bug in flowring management.

      The hash index stored in the flowrings is of type u16 but gets
      stored in u8. This can result in incorrect indexing and possibly
      result in crashes. This patch fixes the type.

      brcmfmac: Inform p2p module about p2pon through API

      When the p2pon module param is used then p2p attach will initialize
      p2p device iface in the firmware, but it is doing that by checking
      data. It is cleaner to pass the p2pon information to p2p by API.
      This information is also needed for other patch.

      64k Tx and Rx buffers are allocated during driver initialization
      for SDIO level data aggregations. When host is under memory
      pressure situation, kzalloc() request for 64k may fail.

      We will try allocating 32k buffers and disable our rx single port
      aggreagation feature in this situation.

      If the allocation still fails, we will disable our sdio multport
      aggregation feature as well. In this way, we will transmit and
      receive packets one by one, thus reduce the demand for big

        - Harmonize itrace's synthesized callchains with the existing 
--max-stack
          tool option. (Adrian Hunter)

        - Allow time to be displayed in nanoseconds in 'perf script'. (Adrian 
Hunter)

        - Fix potential infinite loop when handling Intel PT timestamps. 
(Adrian Hunter)

        - Slighly improve Intel PT debug logging. (Adrian Hunter)

        - Warn when AUX data has been lost, just like when processing 
PERF_RECORD_LOST.
          (Adrian Hunter)

        - Further document export-to-postgresql.py script. (Adrian Hunter)

        - Add option to synthesize branch stack from auxtrace data. (Adrian 
Hunter)

        - Use equivalent logic to avoid using dso->kernel. (Arnaldo Carvalho de

        - Show proper error messages when parsing bad terms for hw/sw events. 
(He Kuang)

        - Tracepoint event parsing improvements. (He Kuang)

        - Store tracing mountpoint for better error message. (Jiri Olsa)

      brcmfmac: Reset PCIE devices after recognition.

      When PCIE type devices are being FW reloaded without being properly
      reset then the device ends up in a locked state, requiring the
      device to be completely powered down. This patch adds a reset
      through watchdog at the moment the device (cores) has been
      recognized. This will solve warm reboot issues.

      brcmfmac: introduce brcmf_net_detach() function

      In case of error during brcmf_bus_start() the network interfaces were
      freed using free_netdev(). However, the interfaces may have additional
      memory allocated which is not freed. The netdev has destructor set to
      brcmf_cfg80211_free_netdev() which frees the additional memory if
      allocated and call free_netdev(). The brcmf_net_detach() either calls
      brcmf_cfg80211_free_netdev() directly or uses unregister_netdev() when
      struct net_device::reg_state indicates the netdev was registered.

      brcmfmac: add dedicated debug level for firmware console logging

      Both PCIe and SDIO devices have the possibility to log the firmware
      console output in kernel log. For PCIe it is logged when PCIE debug
      level is enabled. For SDIO it is logged when user specifies a non-zero
      console interval through debugfs. This patch tries to make it a
      bit more consistent. The firmware console output is only logged when
      FWCON debug level is enabled.

      brcmfmac: add mapping for interface index to bsscfg index

      Because the P2P Device interface in firmware uses the same interface
      index as the primary interface we use the bsscfg index as index in the
      struct brcmf_pub::iflist. However, in the data path we get the interface
      index and not the bsscfg index. So we need a mapping of interface index
      to bsscfg index, which can be determined upon handle adding the interface.

      The sysmmu_fimd1_1 should bind the clock CLK_SMMU_FIMD1M1, not the clock
      CLK_SMMU_FIMD1M0. CLK_SMMU_FIMD1M0 is a clock for the sysmmu_fimd1_0.

      This wrong clock binding causes the problem that is blocked in iommu_map
      function when IOMMU is enabled and exynos-drm driver tries to allocate
      buffer via DMA mapping API on Odroid-XU3 board.

      and hangs randomly because it reads wrong temperature value.

      I can't figure out any direct relation between LDO10 and TMU from board

      net: help compiler generate better code in eth_get_headlen

      Noticed that the compiler (gcc version 4.8.5 20150623 (Red Hat 4.8.5-4) 
(GCC))
      generated suboptimal assembler code in eth_get_headlen().

      This early return coding style is usually not an issue, on super scalar 
CPUs,
      but the compiler choose to put the return statement after this very 
unlikely
      branch, thus creating larger jump down to the likely code path.

      Performance wise, I could measure slightly less L1-icache-load-misses
      and less branch-misses, and an improvement of 1 nanosec with an 
IP-forwarding

      tcp: Fix CWV being too strict on thin streams

      Application limited streams such as thin streams, that transmit small
      amounts of payload in relatively few packets per RTT, can be prevented
      from growing the CWND when in congestion avoidance. This leads to
      increased sojourn times for data segments in streams that often transmit
      time-dependent data.

      Currently, a connection is considered CWND limited only after having
      successfully transmitted at least one packet with new data, while at the
      same time failing to transmit some unsent data from the output queue
      because the CWND is full. Applications that produce small amounts of
      data may be left in a state where it is never considered to be CWND
      limited, because all unsent data is successfully transmitted each time
      an incoming ACK opens up for more data to be transmitted in the send
      window.

      Fix by always testing whether the CWND is fully used after successful
      packet transmissions, such that a connection is considered CWND limited
      whenever the CWND has been filled. This is the correct behavior as
      specified in RFC2861 (section 3.1).

      net/ibm/emac: bump version numbers for correct work with ethtool

      The size of the MAC register dump used to be the size specified by the
      reg property in the device tree.  Userland has no good way of finding
      out that size, and it was not specified consistently for each MAC type,
      so ethtool would end up printing junk at the end of the register dump
      if the device tree didn't match the size it assumed.

      Using the new version numbers indicates unambiguously that the size of
      the MAC register dump is dependent only on the MAC type.

      net/mlx5_core: New init and exit flow for mlx5_core

      In the new flow, we separate the pci initialization and teardown from the

      init_one calls mlx5_pci_init that handles the pci resources 
initialization.
      It then calls mlx5_load_one to initialize the remainder of the resources.

      When removing a device, remove_one is invoked. However, now remove_one
      calls mlx5_unload_one to free all the resources except the pci resources.
      When mlx5_unload_one returns, mlx5_pci_close is called to free the pci
      resources.

      The above separation will allow us to implement the pci error handlers and
      suspend and resume callbacks.

      tcp: avoid reorders for TFO passive connections

      We found that a TCP Fast Open passive connection was vulnerable
      to reorders, as the exchange might look like

      [1] C -> S S <FO ...> <request>
      [2] S -> C S. ack request <options>
      [3] S -> C . <answer>

      packets [2] and [3] can be generated at almost the same time.

      If C receives the 3rd packet before the 2nd, it will drop it as
      the socket is in SYN_SENT state and expects a SYNACK.

      S will have to retransmit the answer.

      Current OOO avoidance in linux is defeated because SYNACK
      packets are attached to the LISTEN socket, while DATA packets
      are attached to the children. They might be sent by different cpus,
      and different TX queues might be selected.

      It turns out that for TFO, we created a child, which is a
      full blown socket in TCP_SYN_RECV state, and we simply can attach
      the SYNACK packet to this socket.

      This means that at the time tcp_sendmsg() pushes DATA packet,
      skb->ooo_okay will be set iff the SYNACK packet had been sent
      and TX completed.

      This removes the reorder source at the host level.

      We also removed the export of tcp_try_fastopen(), as it is no
      longer called from IPv6.

      sctp: Prevent soft lockup when sctp_accept() is called during a timeout 
event

      A case can occur when sctp_accept() is called by the user during
      a heartbeat timeout event after the 4-way handshake.  Since
      sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the
      bh_sock_lock in sctp_generate_heartbeat_event() will be taken with
      the listening socket but released with the new association socket.
      The result is a deadlock on any future attempts to take the listening
      socket lock.

      Note that this race can occur with other SCTP timeouts that take
      the bh_lock_sock() in the event sctp_accept() is called.

      It's possible that while we are waiting for the spinlock, another

      If we then attempt to use the queue, we will panic.

      Intel Wired LAN Driver Updates 2015-09-28

      This series contains updates to i40e, i40evf and igb to resolve issues
      seen and reported by Red Hat.

      Kiran moves i40e_get_head() in preparation for the refactor of the Tx
      timeout logic, so that it can be used in other areas of the driver.
      Refactored the driver timeout logic by issuing a writeback request via
      a software interrupt to the hardware the first time the driver detects
      a hang.  This was due to the driver being too aggressive in resetting a
      hung queue.

      Shannon adds the GRE protocol to the transmit checksum encoding.

      Anjali fixes an issue of forcing writeback too often, which caused us to
      not benefit from NAPI.  We now disable force writeback in the clean
      routine for X710 and XL710 adapters.  The X722 adapters do not enable
      interrupt to force a writeback and benefit from WB_ON_ITR and so force
      WB is left enabled for those adapters.  Fixed a possible deadlock issue
      where sync_vsi_filters() can be called directly under RTNL or through
      the timer subtask without RTNL.  So update the flow to see if we are
      already under RTNL before trying to grab it.

      Stefan Assmann provides a fix for igb where SR-IOV was not getting
      enabled properly and we ran into a NULL pointer if the max_vfs module
      parameter is specified.  This is prevented by setting the
      IGB_FLAG_HAS_MSIX bit before calling igb_probe_vfs().

      v2: added "i40e: Fix for recursive RTNL lock during PROMISC change" patch
          to the series, as it resolves another issues seen and reported by
          Red Hat.

      igb: assume MSI-X interrupts during initialization

      In igb_sw_init() the sequence of calls was changed from
      igb_init_queue_configuration()
      igb_init_interrupt_scheme()
      igb_probe_vfs()
      to
      igb_probe_vfs()
      igb_init_queue_configuration()
      igb_init_interrupt_scheme()

      This results in adapter->flags not having the IGB_FLAG_HAS_MSIX bit set
      during igb_probe_vfs()->igb_enable_sriov(). Therefore SR-IOV does not
      get enabled properly and we run into a NULL pointer if the max_vfs
      module parameter is specified (adapter->vf_data does not get allocated,
      crash on accessing the structure).

      Prevent this by setting the IGB_FLAG_HAS_MSIX bit before calling

      i40e: Fix for recursive RTNL lock during PROMISC change

      The sync_vsi_filters function can be called directly under RTNL
      or through the timer subtask without one. This was causing a deadlock.

      If sync_vsi_filters is called from a thread which held the lock,
      and in another thread the PROMISC setting got changed we would
      be executing the PROMISC change in the thread which already held
      the lock alongside the other filter update. The PROMISC change
      requires a reset if we are on a VEB, which requires it to be called
      under RTNL.

      Earlier the driver would call reset for PROMISC change without
      checking if we were already under RTNL and would try to grab it
      causing a deadlock. This patch changes the flow to see if we are
      already under RTNL before trying to grab it.

      i40e: Fix RS bit update in Tx path and disable force WB workaround

      This patch fixes the issue of forcing WB too often causing us to not
      benefit from NAPI.

      Without this patch we were forcing WB/arming interrupt too often taking
      away the benefits of NAPI and causing a performance impact.

      With this patch we disable force WB in the clean routine for X710
      and XL710 adapters. X722 adapters do not enable interrupt to force
      a WB and benefit from WB_ON_ITR and hence force WB is left enabled
      for those adapters.
      For XL710 and X710 adapters if we have less than 4 packets pending
      a software Interrupt triggered from service task will force a WB.

      This patch also changes the conditions for setting RS bit as described
      in code comments. This optimizes when the HW does a tail bump and when
      it does a WB. It also optimizes when we do a wmb.

      request via a software interrupt to the hardware the first time the

      queue, so back that off by removing logic to down the netdevice after
      too many hangs, and move the function to the service task.

      perf tools: Enable event_config terms to tracepoint events

      This patch enables config terms for tracepoint perf events. Valid terms
      for tracepoint events are 'call-graph' and 'stack-size', so we can use
      different callgraph settings for each event and eliminate unnecessary
      overhead.

      Here is an example for using different call-graph config for each
      tracepoint.

      perf tools: Adds the tracepoint name parsing support

      Adds rules for parsing tracepoint names. Change rules of tracepoint which
      derives from PE_NAMEs into tracepoint names directly, so adding more rules
      based on tracepoint names will be easier.

      Changes v2-v3:
         - Change __event_legacy_tracepoint label in bison file to 
tracepoint_name
         - Fix formats error.

      perf tools: Show proper error message for wrong terms of hw/sw events

      Show proper error message and show valid terms when wrong config terms
      is specified for hw/sw type perf events.

      This patch makes the original error format function formats_error_string()
      more generic, which only outputs the static config terms for hw/sw perf
      events, and prepends pmu formats for pmu events.

      Before this patch:

        $ perf record -e 'cpu-clock/freqx=200/' -a sleep 1
        invalid or unsupported event: 'cpu-clock/freqx=200/'
        Run 'perf list' for a list of valid events

         usage: perf record [<options>] [<command>]
            or: perf record [<options>] -- <command> [<options>]

            -e, --event <event>   event selector. use 'perf list' to list 
available events

      After this patch:

        $ perf record -e 'cpu-clock/freqx=200/' -a sleep 1
        event syntax error: 'cpu-clock/freqx=200/'
                                       \___ unknown term

        valid terms: 
config,config1,config2,name,period,freq,branch_type,time,call-graph,stack-size

        Run 'perf list' for a list of valid events

         usage: perf record [<options>] [<command>]
            or: perf record [<options>] -- <command> [<options>]

            -e, --event <event>   event selector. use 'perf list' to list 
available events

      perf tools: Adds the config_term callback for different type events

      Currently, function config_term() is used for checking config terms of
      all types of events, while unknown terms is not reported as an error
      because pmu events have valid terms in sysfs.

      But this is wrong when unknown terms are specificed to hw/sw events.
      This patch Adds the config_term callback so we can use separate check
      routines for each type of events.

      perf intel-pt: Add mispred-all config option to aid use with autofdo

      autofdo incorrectly expects branch flags to include either mispred or
      predicted.  In fact mispred = predicted = 0 is valid and means the flags
      are not supported, which they aren't by Intel PT.

      To make autofdo work, add a config option which will cause Intel PT
      decoder to set the mispred flag on all branches.

      Below is an example of using Intel PT with autofdo.  The example is
      also added to the Intel PT documentation.  It requires autofdo
      (https://github.com/google/autofdo) and gcc version 5.  The bubble
      sort example is from the AutoFDO tutorial 
(https://gcc.gnu.org/wiki/AutoFDO/Tutorial)
      amended to take the number of elements as a parameter.

        $ gcc-5 -O3 sort.c -o sort_optimized
        $ ./sort_optimized 30000
        Bubble sorting array of 30000 elements
        2254 ms

        $ cat ~/.perfconfig
        [intel-pt]
                mispred-all

        $ perf record -e intel_pt//u ./sort 3000
        Bubble sorting array of 3000 elements
        58 ms
        [ perf record: Woken up 2 times to write data ]
        [ perf record: Captured and wrote 3.939 MB perf.data ]
        $ perf inject -i perf.data -o inj --itrace=i100usle --strip
        $ ./create_gcov --binary=./sort --profile=inj --gcov=sort.gcov 
-gcov_version=1
        $ gcc-5 -O3 -fauto-profile=sort.gcov sort.c -o sort_autofdo
        $ ./sort_autofdo 30000
        Bubble sorting array of 30000 elements
        2155 ms

      Note there is currently no advantage to using Intel PT instead of LBR,
      but that may change in the future if greater use is made of the data.

      perf inject: Add --strip option to strip out non-synthesized events

      Add a new option --strip which is used with --itrace to strip out
      non-synthesized events.  This results in a perf.data file that is
      simpler for external tools to parse.  In particular, this can be used to
      prepare a perf.data file for consumption by autofdo.

      A subsequent patch makes a change to Intel PT also to enable use with
      autofdo and gives an example of that use.

      perf inject can process instruction traces (using the --itrace option)
      which removes aux-related events and replaces them with the requested
      synthesized events.

      However there are still some leftovers, namely PERF_RECORD_ITRACE_START
      events and the original evsel (selected event) e.g. intel_pt//

      For the sake of completeness, remove them too.

      perf script: Make scripting_max_stack value allow for synthesized 
callchains

      perf script has a setting to set the maximum stack depth when processing
      callchains.  The setting defaults to the hard-coded maximum definition
      PERF_MAX_STACK_DEPTH which is 127.

      It is possible, when processing instruction traces, to synthesize
      callchains.  Synthesized callchains do not have the kernel size
      limitation and are whatever size the user requests, although validation
      presently prevents the user requested a value greater that 1024.  The
      default value is 16.

      To allow for synthesized callchains, make the scripting_max_stack value
      at least the same size as the synthesized callchain size.

      limitation and are whatever size the user requests, although validation

      perf intel-pt: Support generating branch stack

      Add support for generating branch stack context for PT samples.  The
      decoder reports a configurable number of branches as branch context for
      each sample. Internally it keeps track of them by using a simple sliding
      window.  We also flush the last branch buffer on each sample to avoid
      overlapping intervals.

      This is useful for:

      - Reporting accurate basic block edge frequencies through the perf
        report branch view
      - Using with --branch-history to get the wider context of samples
      - Other users of LBRs

      Also the Documentation is updated.

      Examples:

        Record with Intel PT:

                perf record -e intel_pt//u ls

        Branch stacks are used by default if synthesized so:

                perf report --itrace=ile

        is the same as:

                perf report --itrace=ile -b

        Branch history can be requested also:

                perf report --itrace=igle --branch-history

      perf inject: Set branch stack feature flag when synthesizing branch stacks

      The branch stack feature flag is set by 'perf record' when recording
      data that contains branch stacks.  Consequently, when 'perf inject'
      synthesizes branch stacks, the feature flag should be set also.

      perf report: Skip events with null branch stacks

      A non-synthesized event might not have a branch stack if branch stacks
      have been synthesized (using itrace options).

      An example of that is when Intel PT records sched_switch events for
      decoding purposes.  Those sched_switch events do not have branch stacks
      even though the Intel PT decoder may be synthesizing other events that
      do due to the itrace options.

      perf report: Adjust sample type validation for synthesized branch stacks

      perf report looks at event sample types to determine if branch stacks
      have been sampled.  Adjust the validation to know about instruction
      tracing options.

      This change allows the use of the -b option which otherwise would
      complain with an error like:

      perf intel-pt: Fix potential loop forever

      TSC packets contain only 7 bytes of TSC.  The 8th byte is assumed to
      change so infrequently that its value can be inferred.  However the
      logic must cater for a 7 byte wraparound, which it does by adding 1 to
      the top byte.

      The existing code was doing that with a while loop even though the
      addition should only need to be done once.  That logic won't work (will
      loop forever) if TSC wraps around at the 8th byte.  Theoretically that
      would take at least 10 years, unless something else went wrong.

      And what else could go wrong.  Well, if the chunks of trace data are
      processed out of order, it will make it look like the 7-byte TSC has
      gone backwards (i.e. wrapped).  If that happens 256 times then stuck in
      the while loop it will be.

      Fix that by getting rid of the unnecessary while loop.

      perf report: Fix sample type validation for synthesized callchains

      Processing instruction tracing data (e.g. Intel PT) can synthesize
      callchains e.g.

        $ perf record -e intel_pt//u uname
        $ perf report --stdio --itrace=ige

      However perf report's callgraph option gets extra validation, so:

        $ perf report --stdio --itrace=ige -gflat
        Error:
        Selected -g or --branch-history but no callchain data. Did
        you call 'perf record' without -g?
        # To display the perf.data header info,
        # please use --header/--header-only options.
        #

      Fix the validation to know about instruction tracing options so
      above command works.

      A side-effect of the change is that the default option to
      accumulate the callchain of child functions comes into force.
      To get the previous behaviour the --no-children option can be
      used e.g.

             $ perf report --stdio --itrace=ige -gflat --no-children

      perf auxtrace: Fix 'instructions' period of zero

      Instruction tracing options (i.e. --itrace) include an option for
      sampling instructions at an arbitrary period. e.g.

        --itrace=i10us

      means make an 'instructions' sample for every 10us of trace.

      Currently the logic does not distinguish between a period of
      zero and no period being specified at all, so it gets treated
      as the default period which is 100000.  That doesn't really
      make sense.

      Fix it so that zero period is accepted and treated as meaning
      "as often as possible".

      In the case of Intel PT that is the same as a period of 1 and
      a unit of 'instructions' (i.e. --itrace=i1i).

      tools build: Add fixdep dependency helper

      For dependency tracking we currently use targets that fall out of the
      gcc -MD command. We store this info in the .cmd file and include as
      makefile during the build.

      This format put object as target and all the c and header files as
      dependencies, like:

        util/abspath.o: util/abspath.c /usr/include/stdc-predef.h util/cache.h \
         /usr/include/bits/wordsize.h /usr/include/gnu/stubs.h \
         ...

      If any of those dependency header files (krava.h below) is removed the
      build fails on:

        make[1]: *** No rule to make target 'krava.h', needed by 'inc.o'.  Stop.

      This patch adds fixdep helper, that is used by kbuild to alter the shape
      of the object dependencies like:

        source_util/abspath.o := util/abspath.c

        deps_util/abspath.o := \
          /usr/include/stdc-predef.h \
          util/cache.h \
          ...

        util/abspath.o: $(deps_util/abspath.o)

        $(deps_util/abspath.o):

      With this format the header removal won't make the build fail, because
      it'll be picked up by the last empty target defined for each header.

      As previously mentioned the fixdep tool is taken from kbuild. It's not
      complete backport, only the part that alters the standard dependency
      info was taken, the part that adds the CONFIG_* dependency logic will be
      probably taken later on.

      x86/xen: Do not clip xen_e820_map to xen_e820_map_entries when sanitizing 
map

      Sanitizing the e820 map may produce extra E820 entries which would result 
in
      the topmost E820 entries being removed. The removed entries would 
typically
      include the top E820 usable RAM region and thus result in the domain 
having
      signicantly less RAM available to it.

      Fix by allowing sanitize_e820_map to use the full size of the allocated 
E820
      array.

      drm/i915: Consider HW CSB write pointer before resetting the sw read 
pointer

      A previous commit resets the Context Status Buffer (CSB) read pointer in
      ring init
          commit c0a03a2e4c4e ("drm/i915: Reset CSB read pointer in ring init")

      This is generally correct, but this pointer is not reset after
      suspend/resume in some platforms (cht). In this case, the driver should
      read the register value instead of resetting the sw read counter to 0.
      Otherwise we process old events, leading to unwanted pre-emptions or
      something worse.

      But in other platforms (bdw) and also during GPU reset or power up, the
      CSBWP is reset to 0x7 (an invalid number), and in this case the read
      pointer should be set to 5 (the interrupt code will increment this
      counter one more time, and will start reading from CSB[0]).

      v2: When the CSB registers are reset, the read pointer needs to be set
      to 5, otherwise the first write (CSB[0]) won't be read (Mika).
      Replace magic numbers with GEN8_CSB_ENTRIES (6) and GEN8_CSB_PTR_MASK
      (0x07).

      x86/xen: Support kexec/kdump in HVM guests by doing a soft reset

      Currently there is a number of issues preventing PVHVM Xen guests from
      doing successful kexec/kdump:

        - Bound event channels.
        - Registered vcpu_info.
        - PIRQ/emuirq mappings.
        - shared_info frame after XENMAPSPACE_shared_info operation.
        - Active grant mappings.

      Basically, newly booted kernel stumbles upon already set up Xen
      interfaces and there is no way to reestablish them. In Xen-4.7 a new
      feature called 'soft reset' is coming. A guest performing kexec/kdump
      operation is supposed to call SCHEDOP_shutdown hypercall with
      SHUTDOWN_soft_reset reason before jumping to new kernel. Hypervisor
      (with some help from toolstack) will do full domain cleanup (but
      keeping its memory and vCPU contexts intact) returning the guest to
      the state it had when it was first booted and thus allowing it to
      start over.

      Doing SHUTDOWN_soft_reset on Xen hypervisors which don't support it is
      probably OK as by default all unknown shutdown reasons cause domain
      destroy with a message in toolstack log: 'Unknown shutdown reason code
      5. Destroying domain.'  which gives a clue to what the problem is and
      eliminates false expectations.

      HYPERVISOR_memory_op() is defined to return an "int" value. This is

      The sub-function XENMEM_maximum_reservation returns the maximum
      number of pages for the current domain. An int will overflow for a
      domain configured with 8TB of memory or more.

      x86/mce: Don't clear shared banks on Intel when offlining CPUs

      It is not safe to clear global MCi_CTL banks during CPU offline
      or suspend/resume operations. These MSRs are either
      thread-scoped (meaning private to a thread), or core-scoped
      (private to threads in that core only), or with a socket scope:
      visible and controllable from all threads in the socket.

      When we offline a single CPU, clearing those MCi_CTL bits will
      stop signaling for all the shared, i.e., socket-wide resources,
      such as LLC, iMC, etc.

      In addition, it might be possible to compromise the integrity of
      an Intel Secure Guard eXtentions (SGX) system if the attacker
      has control of the host system and is able to inject errors
      which would be otherwise ignored when MCi_CTL bits are cleared.

      Hence on SGX enabled systems, if MCi_CTL is cleared, SGX gets
      disabled.

      drm/i915/skl: Don't call intel_prepare_ddi when encoder list isn't yet 
initialized.

      In case something goes wrong with power well initialization we were 
calling
      intel_prepare_ddi during boot while encoder list isnt't initilized.

      So let's protect this case.

      My first attempt was to remove the intel_prepare_ddi, but Daniel had 
pointed out
      this is really needed to restore those registers values. And Imre pointed 
out
      that this case was without the flag protection and this was actually 
where things
      were going bad. So I've just checked and this indeed solves my issue.

      The regressing intel_prepare_ddi call was added in

      m68k: Define asmlinkage_protect

      Make sure the compiler does not modify arguments of syscall functions.
      This can happen if the compiler generates a tailcall to another
      function.  For example, without asmlinkage_protect sys_openat is compiled
      into this function:

      sys_openat:
        clr.l %d0
        move.w 18(%sp),%d0
        move.l %d0,16(%sp)
        jbra do_sys_open

      Note how the fourth argument is modified in place, modifying the register
      %d4 that gets restored from this stack slot when the function returns to
      user-space.  The caller may expect the register to be unmodified across
      system calls.

      Input: serio - fix blocking of parport

      If parkbd_allocate_serio() fails to allocate memory we are releasing the
      parport but we missed unregistering the device. As a result this device
      with exclusive access to that parport remains registered. And no other
      device will be able to use that parport even though this driver has
      failed to load.

      ath: use PRI value given by spec for fixed PRI

      PRI value is used as divider when DFS detector analyzes candidate
      radar pulses.
      If PRI deviation is big from its origin PRI, DFS detector could miss
      valid radar reports since HW often misses detecting radar pulses and
      causes long interval value of pulses.

      For instance from practical results, if runtime PRI is calculated as
      1431 for fixed PRI value of 1428 and delta timestamp logs 15719,
      the modular remainder will be 1409 and the delta between the remainder
      and runtime PRI is 22 that is bigger than PRI tolerance which is 16.
      As a result this radar report will be ignored even though it's valid.

      By using spec defined PRI for fixed PRI, we can correct this error.

      ath: fix incorrect PPB on JAPAN chirp radar

      The number of pulses per burst on Japan chirp radar is
      between 1 and 3. The previous value, 20, is representing
      number of bursts, but since current DFS detector is using
      pulse detection other than bursts, use the pulse number
      for correct radar detection.
      Also using the highest number helps to avoid false detection.

      MIPS: Initialise MAARs on secondary CPUs

      MAARs should be initialised on each CPU (or rather, core) in the system
      in order to achieve consistent behaviour & performance. Previously they
      have only been initialised on the boot CPU which leads to performance
      problems if tasks are later scheduled on a secondary CPU, particularly
      if those tasks make use of unaligned vector accesses where some CPUs
      don't handle any cases in hardware for non-speculative memory regions.
      Fix this by recording the MAAR configuration from the boot CPU and
      applying it to secondary CPUs as part of their bringup.

      irqchip: mips-gic: Fix pending & mask reads for MIPS64 with 32b GIC.

      gic_handle_shared_int reads the GIC interrupt pending & mask registers
      directly into a bitmap, which is defined as an array of unsigned longs.
      The GIC pending registers may be 32 bits wide if the CM is older than
      CM3, regardless of the bit width of the CPU, but for MIPS64 kernels
      the unsigned longs in the bitmap will be 64 bits wide. In this case we
      need to perform 2 x 32 bit reads per 64 bit unsigned long in order to
      avoid missing interrupts.

      this will be the case. Alternatively, if a pre-r6 system implements the
      MT ASE with multiple VPEs per core and Linux is built without support

      ====================
      vxlan: support both IPv4 and IPv6 sockets

      Note: this needs net merged into net-next in order to apply.

      It's currently not easy enough to work with metadata based vxlan tunnels. 
In
      particular, it's necessary to create separate network interfaces for IPv4
      and IPv6 tunneling. Assigning an IPv6 address to an IPv4 interface is
      allowed yet won't do what's expected. With route based tunneling, one has 
to
      pay attention to use the vxlan interface opened with the correct family.
      Other users of this (openvswitch) would need to always create two vxlan
      interfaces.

      Furthermore, there's no sane API for creating an IPv6 vxlan metadata based
      interface.

      This patchset simplifies this by opening both IPv4 and IPv6 socket if the
      vxlan interface has the metadata flag (IFLA_VXLAN_COLLECT_METADATA) set.
      Assignment of addresses etc. works as expected after this.

      vxlan: support both IPv4 and IPv6 sockets in a single vxlan device

      For metadata based vxlan interface, open both IPv4 and IPv6 socket. This 
is
      much more user friendly: it's not necessary to create two vxlan interfaces
      and pay attention to using the right one in routing rules.

      vxlan: make vxlan_sock_add and vxlan_sock_release complementary

      Make vxlan_sock_add both alloc the socket and attach it to vxlan_dev. Let
      vxlan_sock_release accept vxlan_dev as its parameter instead of 
vxlan_sock.

      This makes vxlan_sock_add and vxlan_sock release complementary. It reduces
      code duplication in the next patch.

      8139cp: Fix GSO MSS handling

      When fixing the TSO support I noticed we just mask ->gso_size with the
      MSSMask value and don't care about the consequences.

      Provide a .ndo_features_check() method which drops the NETIF_F_TSO
      feature for any skb which would exceed the maximum, and thus forces it
      to be segmented by software.

      Then we can stop the masking in cp_start_xmit(), and just WARN if the
      maximum is exceeded, which should now never happen.

      Finally, Francois Romieu noticed that we didn't even have the right
      value for MSSMask anyway; it should be 0x7ff (11 bits) not 0xfff.

      - Two more patches to fix most of the MMC regressions with the
        PBIAS regulator changes. At least two MMC driver related issues
        still seems to remain for omap3 legacy booting and omap4 duovero.
        Note that the dts changes depend on a recent regulator fix, and
        are based on the regulator commit now in mainline kernel

      - Enable autoidle for am43xx clocks to prevent clocks from staying
        always on

      - Fix i2c5 pinctrl offsets for omap5-uevm

      - Enable PCA953X as that's needed for HDMI to work on omap5

      ath10k: fix DMA related firmware crashes on multiple devices

      Some platforms really don't like DMA bursts of 256 bytes, and this
      causes the firmware to crash when sending beacons.
      Also, changing this based on the firmware version does not seem to make
      much sense, so use 128 bytes for all versions.

      ath9k inserts padding between the 802.11 header and the data area (to

      tools/power turbostat: SKL: Adjust for TSC difference from base frequency

      On a Skylake with 1500MHz base frequency,
      the TSC runs at 1512MHz.

      This is because the TSC is no longer in the n*100 MHz BCLK domain,
      but is now in the m*24MHz crystal clock domain. (24 MHz * 63 = 1512 MHz)

      This adds error to several calculations in turbostat,
      unless the TSC sample sizes are adjusted for this difference.

      Note that calculations in the time domain are immune
      from this issue, as the timing sub-system has already
      calibrated the TSC against a known wall clock.

      AVG_MHz = APERF_delta/measurement_interval

        need no adjustment.  APERF_delta is in the BCLK domain,
        and measurement_interval is in the time domain.

      TSC_MHz  =  TSC_delta/measurement_interval

        needs no adjustment -- as we really do want to report
        the actual measured TSC delta here, and measurement_interval
        is in the accurate time domain.

      %Busy = MPERF_delta/TSC_delta

        needs adjustment to use TSC_BCLK_DOMAIN_delta.
        TSC_BCLK_DOMAIN_delta = TSC_delta * base_hz / tsc_hz

      Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval

        need adjustment as above.

      No other metrics in turbostat need to be adjusted.

      Before:

           CPU Avg_MHz   %Busy Bzy_MHz TSC_MHz
             -     550   24.84    2216    1512
             0    2191   98.73    2219    1514
             2       0    0.01    2130    1512
             1       9    0.43    2016    1512
             3       2    0.08    2016    1512

      After:

           CPU Avg_MHz   %Busy Bzy_MHz TSC_MHz
             -     550   25.05    2198    1512
             0    2190   99.62    2199    1512
             2       0    0.01    2152    1512
             1       9    0.46    2000    1512
             3       2    0.10    2000    1512

      Note that in this example, the "Before" Bzy_MHz
      was reported as exceeding the 2200 max turbo rate.
      Also, even a pinned spin loop would not be reported
      as over 99% busy.

      tools/power turbostat: KNL workaround for %Busy and Avg_MHz

      KNL increments APERF and MPERF every 1024 clocks.
      This is compliant with the architecture specification,
      which requires that only the ratio of APERF/MPERF need be valid.

      However, turbostat takes advantage of the fact that these
      two MSRs increment every un-halted clock
      at the actual and base frequency:

      AVG_MHz = APERF_delta/measurement_interval

      %Busy = MPERF_delta/TSC_delta

      This quirk is needed for these calculations to also work on KNL,
      which would otherwise show a value 1024x smaller than expected.

      Staring in Linux-4.3-rc1,
      commit 6fb3143b561c ("tools/power turbostat: dump CONFIG_TDP")
      touches MSR 0x648, which is not supported on IVB-Xeon.
      This results in "turbostat --debug" exiting on those systems:

      turbostat: /dev/cpu/2/msr offset 0x648 read failed: Input/output error

      IB/ipoib: increase the max mcast backlog queue

      When performing sendonly joins, we queue the packets that trigger
      the join until the join completes.  This may take on the order of
      hundreds of milliseconds.  It is easy to have many more than three
      packets come in during that time.  Expand the maximum queue depth
      in order to try and prevent dropped packets during the time it
      takes to join the multicast group.

      ACPI, PCI, irq: Do not share PCI IRQ with ISA IRQ

      Avoid IRQs occupied by ISA IRQs when allocating IRQs for PCI link devices,
      otherwise it may cause interrupt storm due to incompatible pin attributes.

      This issue was triggered on a KVM virtual machine, which
       1) uses IRQ9 for SCI in high level mode.
       2) defines an PCI interrupt link device (LNKS) with IRQ9 as the only
          possible irq.
       3) has an PCI device referring to link device LNKS.
      So it causes interrupt storm when enabling the PCI device because PCI IRQ
      works in low level mode.

      "struct acpi_ec_query" at the end of the function cannot be invoked.
      As a consequence, memory leak can be observed.

      dccp/tcp: constify listener sock

      Another patch bomb to prepare lockless TCP/DCCP LISTEN handling.

      SYNACK retransmits are built and sent without listener socket
      being locked. Soon, initial SYNACK packets will have same property.

      This series makes sure we did not something wrong with this model,
      by adding a const qualifier in all the paths taken from synack building
      and transmit, for IPv4/IPv6 and TCP/dccp.

      The only potential problem was the rewrite of ecn bits for connections
      with DCTCP as congestion module, but this was a very minor one.

      This is to document that socket lock might not be held at this point.

      skb_set_owner_w() and ipv6_local_error() are using proper atomic ops
      or spinlocks, so we promote the socket to non const when calling them.

      listener socket is not locked when tcp_make_synack() is called.

      We better make sure no field is written.

      There is one exception : Since SYNACK packets are attached to the listener
      at this moment (or SYN_RECV child in case of Fast Open),
      sock_wmalloc() needs to update sk->sk_wmem_alloc, but this is done using
      atomic operations so this is safe.

      l2tp: module autoloading

      With L2TP it was necessary to manually load modules
      which is a nuisance and not required with other tunneling
      protocols. This set of patches adds the aliases and module
      load hook to get rid of the necessity of modprobing.

      l2tp: auto load type modules

      It should not be necessary to do explicit module loading when

      This patch adds a new module alias type and code to load

      IB/ipoib: Make sendonly multicast joins create the mcast group

      Since IPoIB should, as much as possible, emulate how multicast
      sends work on Ethernet for regular TCP/IP apps, there should be
      no requirement to subscribe to a multicast group before your
      sends are properly sent.  However, due to the difference in how
      multicast is handled on InfiniBand, we must join the appropriate
      multicast group before we can send to it.  Previously we tried
      not to trigger the auto-create feature of the subnet manager when
      doing this because we didn't have tracking of these sendonly
      groups and the auto-creation might never get undone.  The previous
      patch added timing to these sendonly joins and allows us to
      leave them after a reasonable idle expiration time.  So supply
      all of the information needed to auto-create group.

      EDAC: Fix sysfs dimm_label store operation

      Sysfs "dimm_label" and "chX_dimm_label" nodes have the following issues
      in their store operation:

       1) A newline-terminated input string causes redundant newlines:

        # echo "test" > /sys/bus/mc0/devices/dimm0/dimm_label
        # cat  /sys/bus/mc0/devices/dimm0/dimm_label
        test

        #  od -bc /sys/bus/mc0/devices/dimm0/dimm_label
        0000000 164 145 163 164 012 012
                  t   e   s   t  \n  \n
        0000006

       2) The original label string (31 characters) cannot be stored due to
          an improper size check:

        # echo "CPU_SrcID#0_Ha#0_Chan#0_DIMM#0" > 
/sys/bus/mc0/devices/dimm0/dimm_label
        # cat /sys/bus/mc0/devices/dimm0/dimm_label

        # od -bc /sys/bus/mc0/devices/dimm0/dimm_label
         0000000 012 012
                  \n  \n
         0000002

       3) An input string longer than the buffer size results a wrong label
          info as it allows a retry with the remaining string:

        # echo "CPU_SrcID#0_Ha#0_Chan#0_DIMM#0_TEST" > 
/sys/bus/mc0/devices/dimm0/dimm_label
        # cat  /sys/bus/mc0/devices/dimm0/dimm_label
        _TEST

      Fix these issues by making the following changes:
       1) Replace a newline character at the end by setting a null. It also
          assures that the string is null-terminated in the label buffer.
       2) Check the label buffer size with 'sizeof(dimm->label)'.
       3) Fail a request if its string exceeds the label buffer size.

      EDAC: Fix sysfs dimm_label show operation

      After

        7d375bffa524 ("sb_edac: Fix support for systems with two home agents 
per socket")

      sysfs "dimm_label" and "chX_dimm_label" show their label string without a
      newline "\n" at the end.

        [root@orange ~]# cat /sys/bus/mc0/devices/dimm0/dimm_label
        CPU_SrcID#0_Ha#0_Chan#0_DIMM#0[root@orange ~]#

        [root@orange ~]# cat 
/sys/devices/system/edac/mc/mc0/csrow0/ch0_dimm_label
        CPU_SrcID#0_Ha#0_Chan#0_DIMM#0[root@orange ~]#

      The label strings now have 31 characters, which are the same as
      EDAC_MC_LABEL_LEN. Since the snprintf()s in channel_dimm_label_show()
      and dimmdev_label_show() limit the whole length by EDAC_MC_LABEL_LEN,
      the newline in the format "%s\n" is ignored.

        [root@orange ~]# od -bc /sys/bus/mc0/devices/dimm0/dimm_label
        0000000 103 120 125 137 123 162 143 111 104 043 060 137 110 141 043 060
                  C   P   U   _   S   r   c   I   D   #   0   _   H   a   #   0
        0000020 137 103 150 141 156 043 060 137 104 111 115 115 043 060 000

        0000037

      Fix it by using 'sizeof(dimm->label) + 1' as the whole length in the
      snprintf()s in channel_dimm_label_show() and dimmdev_label_show().

      The mediatek pinctrl driver uses the BIT() macro instead of open

      ASoC: db1200: Fix DAI link format for db1300 and db1550

      Commit b4508d0f95fa ("ASoC: db1200: Use static DAI format setup") switched
      the db1200 driver over to using static DAI format setup instead of a
      callback function. But the commit only added the dai_fmt field to one of
      the three DAI links in the driver. This breaks audio on db1300 and db1550.

      Add the two missing dai_fmt settings to fix the issue.

      MODSIGN: Change from CMS to PKCS#7 signing if the openssl is too old

      The sign-file.c program actually uses CMS rather than PKCS#7 to sign a 
file
      since that allows the target X.509 certificate to be specified by
      subjectKeyId rather than by issuer + serialNumber.

      However, older versions of the OpenSSL crypto library (such as may be 
found
      in CentOS 5.11) don't support CMS.  Assume everything prior to
      OpenSSL-1.0.0 doesn't support CMS and switch to using PKCS#7 in that case.

      Further, the pre-1.0.0 OpenSSL only supports PKCS#7 signing with SHA1, so
      give an error from the sign-file script if the caller requests anything
      other than SHA1.

      The compiler gives the following error with an OpenSSL crypto library
      that's too old:

        HOSTCC  scripts/sign-file
      scripts/sign-file.c:23:25: fatal error: openssl/cms.h: No such file or 
directory

      X.509: Don't strip leading 00's from key ID when constructing key 
description

      Don't strip leading zeros from the crypto key ID when using it to 
construct
      the struct key description as the signature in kernels up to and including
      4.2 matched this aspect of the key.  This means that 1 in 256 keys won't
      actually match if their key ID begins with 00.

      The key ID is stored in the module signature as binary and so must be
      converted to text in order to invoke request_key() - but it isn't stripped
      at this point.

      Something like this is likely to be observed in dmesg when the key is 
loaded:

      [    1.572423] Loaded X.509 cert 'Build time autogenerated kernel
          key: 62a7c3d2da278be024da4af8652c071f3fea33'

      followed by this when we try and use it:

        [    1.646153] Request for unknown module key 'Build time autogenerated
          kernel key: 0062a7c3d2da278be024da4af8652c071f3fea33' err -11

      The 'Loaded' line should show an extra '00' on the front of the hex 
string.

      This problem should not affect 4.3-rc1 and onwards because there the key
      should be matched on one of its auxiliary identities rather than the key
      struct's description string.

      KEYS: Fix race between key destruction and finding a keyring by name

      There appears to be a race between:

       (1) key_gc_unused_keys() which frees key->security and then calls
           keyring_destroy() to unlink the name from the name list

       (2) find_keyring_by_name() which calls key_permission(), thus accessing
           key->security, on a key before checking to see whether the key usage 
is 0
           (ie. the key is dead and might be cleaned up).

      Fix this by calling ->destroy() before cleaning up the core key data -
      including key->security.

      IB/mlx5: Remove support for IB_DEVICE_LOCAL_DMA_LKEY

      Commit 96249d70dd70 ("IB/core: Guarantee that a local_dma_lkey
      is available") allows ULPs that make use of the local dma key to keep
      working as before by allocating a DMA MR with local permissions and
      converted these consumers to use the MR associated with the PD
      rather then device->local_dma_lkey.

      ConnectIB has some known issues with memory registration
      using the local_dma_lkey (SEND, RDMA, RECV seems to work ok).

      Thus don't expose support for it (remove device->local_dma_lkey
      setting), and take advantage of the above commit such that no regression
      is introduced to working systems.

      The local_dma_lkey support will be restored in CX4 depending on FW
      capability query.

      xprtrdma: Replace global lkey with lkey local to PD

      The core API has changed so that devices that do not have a global
      DMA lkey automatically create an mr, per-PD, and make that lkey
      available. The global DMA lkey interface is going away in favor of
      the per-PD DMA lkey.

      The per-PD DMA lkey is always available. Convert xprtrdma to use the
      device's per-PD DMA lkey for regbufs, no matter which memory
      registration scheme is in use.

      perf tools: Fix copying of /proc/kcore

      A copy of /proc/kcore containing the kernel text can be made to the
      buildid cache. e.g.

        perf buildid-cache -v -k /proc/kcore

      To workaround objdump limitations, a copy is also made when annotating
      against /proc/kcore.

      The copying process stops working from libelf about v1.62 onwards (the
      problem was found with v1.63).

      The cause is that a call to gelf_getphdr() in kcore__add_phdr() fails
      because additional validation has been added to gelf_getphdr().

      The use of gelf_getphdr() is a misguided attempt to get default
      initialization of the Gelf_Phdr structure.  That should not be
      necessary because every member of the Gelf_Phdr structure is
      subsequently assigned.  So just remove the call to gelf_getphdr().

      Similarly, a call to gelf_getehdr() in gelf_kcore__init() can be
      removed also.

      Committer notes:

      Note to stable@xxxxxxxxxx, from Adrian in the cover letter for this
      patchkit:

      The "Fix copying of /proc/kcore" problem goes back to v3.13 if you think
      it is important enough for stable.

      perf probe: Use existing routine to look for a kernel module by 
dso->short_name

      We have map_groups__find_by_name() to look at the list of modules that
      are in place for a given machine, so use it instead of traversing the
      machine dso list, which also includes DSOs for userspace.

      When merging the user and kernel DSO lists a bug was introduced where
      'perf probe' stopped being able to add probes to modules using its short
      name:

        # perf probe -m usbnet --add usbnet_start_xmit
        usbnet_start_xmit is out of .text, skip it.
          Error: Failed to add events.
        #

      With this fix it works again:

        # perf probe -m usbnet --add usbnet_start_xmit
        Added new event:
          probe:usbnet_start_xmit (on usbnet_start_xmit in usbnet)

        You can now use it in all perf tools, such as:

                perf record -e probe:usbnet_start_xmit -aR sleep 1

      KVM: disable halt_poll_ns as default for s390x

      We observed some performance degradation on s390x with dynamic
      halt polling. Until we can provide a proper fix, let's enable
      halt_poll_ns as default only for supported architectures.

      Architectures are now free to set their own halt_poll_ns
      default value.

      KVM: x86: fix off-by-one in reserved bits check

      29ecd6601904 ("KVM: x86: avoid uninitialized variable warning",
      2015-09-06) introduced a not-so-subtle problem, which probably
      escaped review because it was not part of the patch context.

      Before the patch, leaf was always equal to iterator.level.  After,
      it is equal to iterator.level - 1 in the call to is_shadow_zero_bits_set,
      and when is_shadow_zero_bits_set does another "-1" the check on
      reserved bits becomes incorrect.  Using "iterator.level" in the call
      fixes this call trace:

      KVM: x86: use correct page table format to check nested page table 
reserved bits

      Intel CPUID on AMD host or vice versa is a weird case, but it can
      happen.  Handle it by checking the host CPU vendor instead of the
      guest's in reset_tdp_shadow_zero_bits_mask.  For speed, the
      check uses the fact that Intel EPT has an X (executable) bit while
      AMD NPT has NX.

      KVM: svm: do not call kvm_set_cr0 from init_vmcb

      kvm_set_cr0 may want to call kvm_zap_gfn_range and thus access the
      memslots array (SRCU protected).  Using a mini SRCU critical section
      is ugly, and adding it to kvm_arch_vcpu_create doesn't work because
      the VMX vcpu_create callback calls synchronize_srcu.

      x86/asm: Force inlining of cpu_relax()

      On x86, cpu_relax() simply calls rep_nop(), which generates one
      instruction, PAUSE (aka REP NOP).

      With this config:

        http://busybox.net/~vda/kernel_config_OPTIMIZE_INLINING_and_Os

      gcc-4.7.2 does not always inline rep_nop(): it generates several
      copies of this:

        <rep_nop> (16 copies, 194 calls):
             55                      push   %rbp
             48 89 e5                mov    %rsp,%rbp
             f3 90                   pause
             5d                      pop    %rbp
             c3                      retq

      See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66122

      This patch fixes this via s/inline/__always_inline/
      on rep_nop() and cpu_relax().

      ( Forcing inlining only on rep_nop() causes GCC to
        deinline cpu_relax(), with almost no change in generated code).

      x86/sched/64: Don't save flags on context switch (reinstated)

      This reinstates the following commit:

        2c7577a75837 ("sched/x86_64: Don't save flags on context switch")

      which was reverted in:

        512255a2ad2c ("Revert 'sched/x86_64: Don't save flags on context 
switch'")

      Historically, Linux has always saved and restored EFLAGS across
      context switches.  As far as I know, the only reason to do this
      is because of the NT flag.  In particular, if something calls
      switch_to() with the NT flag set, then we don't want to leak the
      NT flag into a different task that might try to IRET and fail
      because NT is set.

      Before this commit:

        8c7aa698baca ("x86_64, entry: Filter RFLAGS.NT on entry from userspace")

      we could run system call bodies with NT set.  This would be a DoS or 
possibly
      privilege escalation hole if scheduling in such a system call would leak
      NT into a different task.

      Importantly, we don't need to worry about NT being set while
      preemptible or across page faults.  The only way we can schedule
      due to preemption or a page fault is in an interrupt entry that
      nests inside the SYSENTER prologue.  The CPU will clear NT when
      entering through an interrupt gate, so we won't schedule with NT
      set.

      The only other interesting flags are IOPL and AC.  Allowing
      switch_to() to change IOPL has no effect, as the value loaded
      during kernel execution doesn't matter at all except between a
      SYSENTER entry and the subsequent PUSHF, and anythign that
      interrupts in that window will restore IOPL on return.

      If we call __switch_to() with AC set, we have bigger problems.

      iscsi-target: Avoid OFMarker + IFMarker negotiation

      This patch fixes a v4.2+ regression introduced by commit c04a6091
      that removed support for obsolete sync-and-steering markers usage
      as originally defined in RFC-3720.

      The regression would involve attempting to send OFMarker=No +
      IFMarker=No keys during opertional negotiation login phase,
      including when initiators did not actually propose these keys.

      The result for MSFT iSCSI initiators would be random junk in
      TCP stream after the last successful login request was been sent
      signaling the move to full feature phase (FFP) operation.

      To address this bug, go ahead and avoid negotiating these keys
      by default unless the initiator explicitly proposes them, but
      still respond to them with 'No' if they are proposed.

      target: Propigate backend read-only to core_tpg_add_lun

      This patch adds a DF_READ_ONLY flag that is used by IBLOCK to
      signal when a backend has been set to read-only mode, in order
      to propigate read-only status up to core_tpg_add_lun() for all
      future LUN fabric exports.

      With this is place, existing emulation for reporting read-only
      in spc_emulate_modesense() and normal transport_lookup_cmd_lun()
      TCM_WRITE_PROTECTED status checking just works as expected.

      target: Fix PR registration + APTPL RCU conversion regression

      This patch fixes a v4.2+ regression introduced by commit 79dc9c9e86
      where lookup of t10_pr_registration->pr_reg_deve and associated
      ->pr_kref get was missing from __core_scsi3_do_alloc_registration(),
      which is responsible for setting DEF_PR_REG_ACTIVE.

      This would result in REGISTER operations completing successfully,
      but subsequent core_scsi3_pr_seq_non_holder() checking would fail
      with !DEF_PR_REG_ACTIVE -> RESERVATION CONFLICT status.

      Update __core_scsi3_add_registration() to drop ->pr_kref reference
      after registration and any optional ALL_TG_PT=1 processing has
      completed.  Update core_scsi3_decode_spec_i_port() to release
      the new parent local_pr_reg->pr_kref as well.

      Also, update __core_scsi3_check_aptpl_registration() to perform
      the same target_nacl_find_deve() lookup + ->pr_kref get, now that
      __core_scsi3_add_registration() expects to drop the reference.

      Finally, since there are cases when se_dev_entry->se_lun_acl can
      still be dereferenced in core_scsi3_lunacl_undepend_item() while
      holding ->pr_kref, go ahead and move explicit rcu_assign_pointer()
      NULL assignments within core_disable_device_list_for_node() until
      after orig->pr_comp finishes.

      Phy, mdiobus, and netdev struct device fixes

      The third version of this series fixes the build error which David
      identified, and drops the broken changes for the Cavium Thunger BGX
      ethernet driver as this driver requires some complex changes to
      resolve the leakage - and this is best done by people who can test
      the driver.

      Compared to v2, the only patch which has changed is patch 6
        "net: fix phy refcounting in a bunch of drivers"

      I _think_ I've been able to build-test all the drivers touched by
      that patch to some degree now, though several of them needed the
      Kconfig hacked to allow it (not all had || COMPILE_TEST clause on
      their dependencies.)

      Previous cover letters below:

      This is the second version of the series, with the comments David had
      on the first patch fixed up.  Original series description with updated
      diffstat below.

      While looking at the DSA code, I noticed we have a
      of_find_net_device_by_node(), and it looks like users of that are
      similarly buggy - it looks like net/dsa/dsa.c is the only user.  Fix
      that too.

      Hi,

      While looking at the phy code, I identified a number of weaknesses
      where refcounting on device structures was being leaked, where
      modules could be removed while in-use, and where the fixed-phy could
      end up having unintended consequences caused by incorrect calls to
      fixed_phy_update_state().

      This patch series resolves those issues, some of which were discovered
      with testing on an Armada 388 board.  Not all patches are fully tested,
      particularly the one which touches several network drivers.

      When resolving the struct device refcounting problems, several different
      solutions were considered before settling on the implementation here -
      one of the considerations was to avoid touching many network drivers.
      The solution here is:

        phy_attach*() - takes a refcount
        phy_detach*() - drops the phy_attach refcount

      Provided drivers always attach and detach their phys, which they should
      already be doing, this should change nothing, even if they leak a 
refcount.

        of_phy_find_device() and of_* functions which use that take
        a refcount.  Arrange for this refcount to be dropped once
        the phy is attached.

      This is the reason why the previous change is important - we can't drop
      this refcount taken by of_phy_find_device() until something else holds
      a reference on the device.  This resolves the leaked refcount caused by
      using of_phy_connect() or of_phy_attach().

      Even without the above changes, these drivers are leaking by calling
      of_phy_find_device().  These drivers are addressed by adding the
      appropriate release of that refcount.

      The mdiobus code also suffered from the same kind of leak, but thankfully
      this only happened in one place - the mdio-mux code.

      I also found that the try_module_get() in the phy layer code was utterly
      useless: phydev->dev.driver was guaranteed to always be NULL, so
      try_module_get() was always being called with a NULL argument.  I proved
      this with my SFP code, which declares its own MDIO bus - the module use
      count was never incremented irrespective of how I set the MDIO bus up.
      This allowed the MDIO bus code to be removed from the kernel while there
      were still PHYs attached to it.

      One other bug was discovered: while using in-band-status with mvneta, it
      was found that if a real phy is attached with in-band-status enabled,
      and another ethernet interface is using the fixed-phy infrastructure, the
      interface using the fixed-phy infrastructure is configured according to
      the other interface using the in-band-status - which is caused by the
      fixed-phy code not verifying that the phy_device passed in is actually
      a fixed-phy device, rather than a real MDIO phy.

      Lastly, having mdio_bus reversing phy_device_register() internals seems
      like a layering violation - it's trivial to move that code to the phy
      device layer.

      net: fix phy refcounting in a bunch of drivers

      of_phy_find_device() increments the phy struct device refcount, which
      we need to properly balance.  Add code to network drivers using this
      function to ensure that the struct device refcount is correctly
      balanced.

      For xgene, looking back in the history, we should be able to use
      of_phy_connect() with a zero flags argument for the DT case as this is
      how the driver used to operate prior to de7b5b3d790a ("net: eth: xgene:
      change APM X-Gene SoC platform ethernet to support ACPI").

      This leaves the Cavium Thunder BGX unfixed; fixing this driver is a
      complicated task, one which the maintainers need to be involved with.

      of_mdio: fix MDIO phy device refcounting

      bus_find_device() is defined as:

       * This is similar to the bus_for_each_dev() function above, but it
       * returns a reference to a device that is 'found' for later use, as
       * determined by the @match callback.

      and it does indeed return a reference-counted pointer to the device:

              while ((dev = next_device(&i)))
                      if (match(dev, data) && get_device(dev))
                                              ^^^^^^^^^^^^^^^
                              break;
              klist_iter_exit(&i);
              return dev;

      What that means is that when we're done with the struct device, we must
      drop that reference.  Neither of_phy_connect() nor of_phy_attach() did
      this when phy_connect_direct() or phy_attach_direct() failed.

      With our previous patch, phy_connect_direct() and phy_attach_direct()
      take a new refcount on the phy device when successful, so we can drop
      our local reference immediatley after these functions, whether or not
      they succeeded.

      phy: fix mdiobus module safety

      Re-implement the mdiobus module refcounting to ensure that we actually
      ensure that the mdiobus module code does not go away while we might call
      into it.

      The old scheme using bus->dev.driver was buggy, because bus->dev is a
      class device which never has a struct device_driver associated with it,
      and hence the associated code trying to obtain a refcount did nothing
      useful.

      Instead, take the approach that other subsystems do: pass the module
      when calling mdiobus_register(), and record that in the mii_bus struct.
      When we need to increment the module use count in the phy code, use
      this stored pointer.  When the phy is deteched, drop the module
      refcount, remembering that the phy device might go away at that point.

      This doesn't stop the mii_bus going away while there are in-use phys -
      it merely stops the underlying code vanishing.

      net: dsa: fix of_mdio_find_bus() device refcount leak

      Current users of of_mdio_find_bus() leak a struct device refcount, as
      they fail to clean up the reference obtained inside class_find_device().

      Fix the DSA code to properly refcount the returned MDIO bus by:
      1. taking a reference on the struct device whenever we assign it to
         pd->chip[x].host_dev.
      2. dropping the reference when we overwrite the existing reference.
      3. dropping the reference when we free the data structure.
      4. dropping the initial reference we obtained after setting up the
         platform data structure, or on failure.

      In step 2 above, where we obtain a new MDIO bus, there is no need to
      take a reference on it as we would only have to drop it immediately
      after assignment again, iow:

        put_device(cd->host_dev);       /* drop original assignment ref */
        cd->host_dev = get_device(&mdio_bus_switch->dev); /* get our ref */

      dmaengine: idma64: improve residue estimation

      The residue calculation may provide a wrong estimation when the transfer 
is
      started. There are possible scenarios we have to separate:

        1) the transfer is not started yet; residue is equal to the total
           length;

        2) the transfer is just started (first chunk is ongoing); residue is
           equal to the total length without already transfered bytes;

        3) the transfer is ongoing and we already sent few chunks of data;
           residue is equal to the total length without fully transfered chunks
           and already sent bytes.

      Mistakenly the calculation in cases 2) and 3) was done in the similar way 
and
      the result is equal to -bytes that have been transfered, i.e. quite big 
since
      size_t type can't keep negative values.

      Rewrite the calculation algorithm to be one pass and have a correct 
result.

      Besides above in case user asks for a status of the active DMA descriptor
      without pausing an ongoing transfer the residue will be estimated based 
on the
      register value, though it's still racy. Since the transfer is active the 
value
      is continuously being changed. Here we have to read two registers at a 
time. To
      minimize an error make those reads close to each other.

      ====================
      Second Round of IPVS Updates for v4.4

      please consider these bug fixes and extensive clean-ups of IPVS
      from Eric Biederman for v4.4.

      His excellent description of the changes, which is part of an even larger
      set of clean-up work, is as follows:

        I am gradually working my way through the netfilter stack passing struct
        down into the netfilter hooks and from the netfilter hooks and from 
there
        down into the functions that actually care.  This removes the need for
        netfilter functions to guess how to figure out how to compute which
        network namespace they are in and instead provides a simple and reliable
        method to do so.

        The cleanups stand on their own but this is part of a larger effort to
        have routes with an output device that is not in the current network
        namespace.

        The IPVS code has been a bit more of a challenge than most.  Just 
passing
        struct net through to where it is needed did not feel clean to me.  The
        practical issue is that the ipvs code in most places actually wants
        struct netns_ipvs and not struct net.

        So as part of this process I have turned the relationship between struct
        net and the structs netns_ipvs, ip_vs_conn_param, ip_vs_conn, and
        ip_vs_service inside out.  I have modified the ipvs functions to take a
        struct netns_ipvs not a struct net.  The net is code with fewer
        conversions from one type of structure to another.  I did wind up adding
        a struct netns_ipvs parameter to quite a few functions that did not have
        it before so I could pass the structure down from the netfilter hooks to
        where it is actually needed to avoid guessing.

        I have broken up the work in a bunch of small patches so there is at
        least a chance and reviewing that each step I took is correct.  The
        series compiles at each step so bisecting it should not be a problem if
        something weird comes up.

        The first two changes in this series are actually bug fixes.  The first
        is a compile fix for a bug in sctp that came in, in the last round of
        ipvs changes merged into nf-next.  The second fixes an older bug where 
in
        pathological circumstances the wrong network namespace could be used 
when
        a proc file is written to.

        The rest of the patchset is a bunch of boring changes getting pushing
        struct netns_ipvs (and by extension ipvs->net) where it needs to be.
        Either by replacing struct net pointers or adding new struct netns_ipvs
        pointers.  With a handful of other minor cleanups (like removing
        skb_net).

      I have decided include the bug fixes in this pull request. Patch one
      relates to a bug that was added to nf-next recently and is thus not
      applicable to nf . Patch two could arguably be promoted to a fix for v4.3
      and stable though it does not appear to be severe enough to warrant that
      course of action; let me know if you would like me to reconsider.

      ip6_tunnel: Reduce log level in ip6_tnl_err() to debug

      Currently error log messages in ip6_tnl_err are printed at 'warn'
      level. This is different to other tunnel types which don't print
      any messages. These log messages don't provide any information that
      couldn't be deduced with networking tools. Also it can be annoying
      to have one end of the tunnel go down and have the logs fill with
      pointless messages such as "Path to destination invalid or inactive!".

      This patch reduces the log level of these messages to 'dbg' level to
      bring the visible behaviour into line with other tunnel types.

      Documentation: arm: Fix typo in the idle-states bindings examples

      The idle-states bindings mandate that the entry-method string
      in the idle-states node must be "psci" for ARM v8 64-bit systems,
      but the examples in the bindings report a wrong entry-method string.
      Owing to this typo, some dts in the kernel wrongly defined the
      entry-method property, since they likely cut and pasted the example
      definition without paying attention to the bindings definitions.

      This patch fixes the typo in the DT idle states bindings examples and
      respective dts in the kernel so that the bindings and related dts
      files are made compliant.

      gpio: mention in DT binding doc that <name>-gpio is deprecated

      The gpiolib supports parsing DT properties of the form <name>-gpio but it
      was only added for compatibility with older DT bindings that got it wrong
      and should not be used in newer bindings.

      The commit that added support for this was:

      dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property names")

      but didn't update the documentation to explain this so it's been a source
      of confusion. So let's make this clear in the GPIO DT binding doc.

      Intel Wired LAN Driver Updates 2015-09-23

      This series contains updates to ixgbe only.

      Mark provides all the changes in this series, first clears the destination
      location for I2C data initially so that the received data will not be
      corrupted by previous attempts.  Then reduced the pauses/delays in the
      PHY detection when no SFP is present by reducing the number of retires,
      once an SFP is detected, the "normal" number of retries in PHY detection
      will be used.  Added support for X55EM_x SFP+ dual-speed, and fixed 1G and
      10G link stability for X550EM_x by configuring the CS4227 correctly by
      moving code to ixgbe_setup_mac_link_sfp_x550em().  Added functionality to
      reset CS4227, since on some platforms the CS4227 does not initialize
      properly.  Next reduces the SFP polling rate, due to when an SFP is not
      present, the I2C timeouts that result are very costly.  So prevent the
      SFP polling from being done more than once every two seconds.  Added
      support for I2C bus MUX.  Fixed the setting of RDRXCTL register which
      should fall through X540 and 82599, not 82598.  In addition, added small
      packet padding support in X550 by setting RDRXCTL.PSP when the driver is
      in SRIOV mode.  Fixed a known hardware issue where the PCI transactions
      pending bit sticks high when there are pending transactions, so
      workaround the issue by wait and then continue with our reset flow.
      Added a new device ID for X550EM device with SFPs.  Provided a fix with
      the DCA setup, which was suggested by Alex Duyck <aduyck@xxxxxxxxxxxx>,
      by making it so that we always set the relaxed ordering bits related to
      the DCA registers even if DCA is not enbaled.  Then moves the
      configuration out of the ixgbe_down() and into ixgbe_configure() before
      enabling the transmit and receive rings.  This ensures that DCA is
      configured correctly before starting the processing of packets.
      Fixed VM-to-VM loopback mode which requires that FCRTH be set, but
      the datasheets did not specify what the value should be.  It has now
      been determined that the correct value should be RXPBSIZE - (24*1024).

      ip6_gre: Reduce log level in ip6gre_err() to debug

      Currently error log messages in ip6gre_err are printed at 'warn'
      level. This is different to most other tunnel types which don't
      print any messages. These log messages don't provide any information
      that couldn't be deduced with networking tools. Also it can be annoying
      to have one end of the tunnel go down and have the logs fill with
      pointless messages such as "Path to destination invalid or inactive!".

      This patch reduces the log level of these messages to 'dbg' level to
      bring the visible behaviour into line with other tunnel types.

      fib_rules: fix fib rule dumps across multiple skbs

      dump_rules returns skb length and not error.
      But when family == AF_UNSPEC, the caller of dump_rules
      assumes that it returns an error. Hence, when family == AF_UNSPEC,
      we continue trying to dump on -EMSGSIZE errors resulting in
      incorrect dump idx carried between skbs belonging to the same dump.
      This results in fib rule dump always only dumping rules that fit
      into the first skb.

      This patch fixes dump_rules to return error so that we exit correctly
      and idx is correctly maintained between skbs that are part of the
      same dump.

      PCI: Use function 0 VPD for identical functions, regular VPD for others

      932c435caba8 ("PCI: Add dev_flags bit to access VPD through function 0")
      added PCI_DEV_FLAGS_VPD_REF_F0.  Previously, we set the flag on every
      non-zero function of quirked devices.  If a function turned out to be
      different from function 0, i.e., it had a different class, vendor ID, or
      device ID, the flag remained set but we didn't make VPD accessible at all.

      Flip this around so we only set PCI_DEV_FLAGS_VPD_REF_F0 for functions 
that
      are identical to function 0, and allow regular VPD access for any other
      functions.

      PCI: Fix devfn for VPD access through function 0

      Commit 932c435caba8 ("PCI: Add dev_flags bit to access VPD through 
function
      0") passes PCI_SLOT(devfn) for the devfn parameter of pci_get_slot().
      Generally this works because we're fairly well guaranteed that a PCIe
      device is at slot address 0, but for the general case, including
      conventional PCI, it's incorrect.  We need to get the slot and then 
convert
      it back into a devfn.

      PCI/MSI: Fix MSI IRQ domains for VFs on virtual buses

      SR-IOV creates a virtual bus where bus->self is NULL.  When we add VFs and
      scan for an MSI domain, pci_set_bus_msi_domain() dereferences bus->self,
      which causes a kernel NULL pointer dereference oops.

      Scan up to the parent bus until we find a real bridge where we can get the
      MSI domain.

      bnx2x: byte swap rss_key to comply to Toeplitz specs

      After a good amount of debugging, I found bnx2x was byte swaping
      the 40 bytes of rss_key.

      If we byte swap the key, then bnx2x generates hashes matching
      MSDN specs as documented in (Verifying the RSS Hash Calculation)

      https://msdn.microsoft.com/en-us/library/windows/hardware/ff571021%
      28v=vs.85%29.aspx

      It is mostly a non issue, unless we want to mix different NIC
      in a host, and want consistent hashing among all of them, ie
      if they all use the boot time generated rss key, or if some application
      is choosing specific tuple(s) so that incoming traffic lands into known
      rx queue(s).

      Jiri Benc says:

      ====================
      lwtunnel: make it really work, for IPv4

      One of the selling points of lwtunnel was the ability to specify the 
tunnel
      destination using routes. However, this doesn't really work currently, as
      ARP and ndisc replies are not handled correctly. ARP and ndisc replies 
won't
      have tunnel metadata attached, thus they will be sent out with the default
      parameters or not sent at all, either way never reaching the requester.

      Most of the egress tunnel parameters can be inferred from the ingress
      metada. The only and important exception is UDP ports. This patchset 
infers
      the egress data from the ingress data and disallow settings of UDP ports 
in
      tunnel routes. If there's a need for different UDP ports, a new interface
      needs to be created for each port combination. Note that it's still 
possible
      to specify the UDP ports to use, it just needs to be done while creating 
the
      vxlan/geneve interface.

      This covers only ARPs. IPv6 ndisc has the same problem but is harder to
      solve, as there's already dst attached to outgoing skbs. Ideas to solve 
this
      are welcome.

      lwtunnel: remove source and destination UDP port config option

      The UDP tunnel config is asymmetric wrt. to the ports used. The source and
      destination ports from one direction of the tunnel are not related to the
      ports of the other direction. We need to be able to respond to ARP 
requests
      using the correct ports without involving routing.

      As the consequence, UDP ports need to be fixed property of the tunnel
      interface and cannot be set per route. Remove the ability to set ports per
      route. This is still okay to do, as no kernel has been released with these
      attributes yet.

      Note that the ability to specify source and destination ports is preserved
      for other users of the lwtunnel API which don't use routes for tunnel key
      specification (like openvswitch).

      If in the future we rework ARP handling to allow port specification, the
      attributes can be added back.

      ipv4: send arp replies to the correct tunnel

      When using ip lwtunnels, the additional data for xmit (basically, the 
actual
      tunnel to use) are carried in ip_tunnel_info either in dst->lwtstate or in
      metadata dst. When replying to ARP requests, we need to send the reply to
      the same tunnel the request came from. This means we need to construct
      proper metadata dst for ARP replies.

      We could perform another route lookup to get a dst entry with the correct
      lwtstate. However, this won't always ensure that the outgoing tunnel is 
the
      same as the incoming one, and it won't work anyway for IPv4 duplicate
      address detection.

      The only thing to do is to "reverse" the ip_tunnel_info.

      skbuff: Fix skb checksum flag on skb pull

      VXLAN device can receive skb with checksum partial. But the checksum
      offset could be in outer header which is pulled on receive. This results
      in negative checksum offset for the skb. Such skb can cause the assert
      failure in skb_checksum_help(). Following patch fixes the bug by setting
      checksum-none while pulling outer header.

      Following is the kernel panic msg from old kernel hitting the bug.

      cgroup, writeback: don't enable cgroup writeback on traditional 
hierarchies

      inode_cgwb_enabled() gates cgroup writeback support.  If it returns
      true, each inode is attached to the corresponding memory domain which
      gets mapped to io domain.  It currently only tests whether the
      filesystem and bdi support cgroup writeback; however, cgroup writeback
      support doesn't work on traditional hierarchies and thus it should
      also test whether memcg and iocg are on the default hierarchy.

      This caused traditional hierarchy setups to hit the cgroup writeback
      path inadvertently and ended up creating separate writeback domains
      for each memcg and mapping them all to the root iocg uncovering a
      couple issues in the cgroup writeback path.

      cgroup writeback was never meant to be enabled on traditional
      hierarchies.  Make inode_cgwb_enabled() test whether both memcg and
      iocg are on the default hierarchy.

      OK I've decided to drop the acquire/release helpers as they don't
      help us at all and simply pessimises the code by using full memory
      barriers (on some architectures) where only a write or read barrier
      is needed.

      But you are right we do need an explicit write barrier here to
      ensure that the hashing is visible.

      It's not about being overly smart.  It's about actually understanding
      what's going on with the code.  I've seen too many instances of
      people simply sprinkling synchronisation primitives around without
      any knowledge of what is happening underneath, which is just a recipe
      for creating hard-to-debug races.

      The reason this one is OK is because we do not use nlk->portid or
      try to get nlk from the hash table before we return to user-space.

      However, there is a real bug here that none of these acquire/release
      helpers discovered.  The two bound tests here used to be a single
      one.  Now that they are separate it is entirely possible for another
      thread to come in the middle and bind the socket.  So we need to
      repeat the portid check in order to maintain consistency.

      The commit 1f770c0a09da855a2b51af6d19de97fb955eca85 ("netlink:
      Fix autobind race condition that leads to zero port ID") created
      some new races that can occur due to inconcsistencies between the
      two port IDs.

      Tejun is right that a barrier is unavoidable.  Therefore I am
      reverting to the original patch that used a boolean to indicate
      that a user netlink socket has been bound.

      Barriers have been added where necessary to ensure that a valid
      portid and the hashed socket is visible.

      I have also changed netlink_insert to only return EBUSY if the
      socket is bound to a portid different to the requested one.  This
      combined with only reading nlk->bound once in netlink_bind fixes
      a race where two threads that bind the socket at the same time
      with different port IDs may both succeed.

      ALSA: hda - Disable power_save_node for Thinkpads

      Lenovo Thinkpads with recent Realtek codecs seem suffering from click
      noises at power transition since the introduction of widget power
      saving in 4.1 kernel.  Although this might be solved by some delays in
      appropriate points, as a quick workaround, just disable the
      power_save_node feature for now.  The gain it gives is relatively
      small, and this makes the situation back to pre 4.1 time.

      This patch ended up with a bit more code changes than usual because
      the existing fixup for Thinkpads is highly chained.  Instead of adding
      yet another chain, combine a few of them into a single fixup entry, as
      a gratis cleanup.

      EDAC, sb_edac: Fix TAD presence check for sbridge_mci_bind_devs()

      In commit

        7d375bffa524 ("sb_edac: Fix support for systems with two home agents 
per socket")

      NUM_CHANNELS was changed to 8 and the channel space was renumerated to
      handle EN, EP, and EX configurations.

      The *_mci_bind_devs() functions - except for sbridge_mci_bind_devs() -
      got a new device presence check in the form of saw_chan_mask. However,
      sbridge_mci_bind_devs() still uses the NUM_CHANNELS for loop.

      With the increase in NUM_CHANNELS, this loop fails at index 4 since
      SB only has 4 TADs.  This results in the following error on SB machines:

        EDAC sbridge: Some needed devices are missing
        EDAC sbridge: Couldn't find mci handler
        EDAC sbridge: Couldn't find mci handle

      This patch adapts the saw_chan_mask logic for sbridge_mci_bind_devs() as
      well.

      gpio: keep the GPIO line names internal

      This refactors the changes to the GPIO line naming mechanism to
      not have so widespread effects, instead we conclude the patch series
      by having created a name attribute in the GPIO descriptor, that need
      not be globally unique, and it will be initialized from the old
      .names array in struct gpio_chip if it exists, then used in the legacy
      sysfs code like the array was used previously.

      The associated changes to name lines from the device tree are
      controversial and need to stand alone from this. Resulting changes:

      1. Remove the export and the header for the gpio_name_to_desc() as so
      far the only use is inside gpiolib.c. Staticize gpio_name_to_desc()
      and move it above the only function using it.

      2. Only print a warning if there are two GPIO lines with the same name.
      The reason is to preserve current behaviour: before the previous
      changes to the naming mechanism this would not reject probing the
      driver, instead the error would occur when trying to export the line
      in sysfs, so restore this behaviour, but print a friendly warning
      if names collide.

      gpio: Introduce gpio descriptor 'name'

      The latest gpio hogging mechanism assigns each gpio a 'line-name' in the
      devicetree. The 'name' field is different from the 'label' field.
      'label' is only used for requested GPIOs to describe its current use by
      driver or userspace.

      The 'name' field describes the GPIO itself, not the use. This is most
      likely identical to the label in the schematic on the GPIO line and
      should help to find this particular GPIO.

      This is equivalent to the gpiochip->names array. However names should be
      stored in the GPIO descriptor. We will use gpiochip->names in the future
      only as initializer for the GPIO descriptors for drivers that assign
      GPIO names hardcoded. All other GPIO names will be parsed from DT and
      directly assigned to the GPIO descriptor.

      This patch adds a helper function to find gpio descriptors by name

      Bluetooth: Remove useless rx_lock spinlock

      rx_lock spinlock is only used in hci_uart_tty_receive() which is the
      receive_buf ldisc callback.

      hci_uart_tty_receive() is protected from re-entrance by its only
      caller (flush_to_ldisc() in drivers/tty/tty_buffer.c) which held a
      mutex (buf->lock) for this section.
      This lock allows "safe use of the line discipline's receive_buf()
      method by excluding the buffer work and any pending flush from using
      the flip buffer." (comments from tty_buffer_lock_exclusive() in
      drivers/tty/tty_buffer.c)

      So, no need to double protect this resource with rx_lock.

      ALSA: hda/tegra - async probe for avoiding module loading deadlock

      The Tegra HD-audio controller driver causes deadlocks when loaded as a
      module since the driver invokes request_module() at binding with the
      codec driver.  This patch works around it by deferring the probe in a
      work like Intel HD-audio controller driver does.  Although hovering
      the codec probe stuff into udev would be a better solution, it may
      cause other regressions, so let's try this band-aid fix until the more
      proper solution gets landed.

      When the kernel is compiled with -Os (CONFIG_CC_OPTIMIZE_FOR_SIZE), 
tridentfb
      hangs the machine upon load with Blade3D cards unless acceleration is 
disabled.

      This is caused by memcpy() which copies data byte-by-byte (rep movsb) when
      compiled with -Os. The card does not like that - it requires 32-bit 
access.

      Use iowrite_32() instead.

      drm: Allow also control clients to check the drm version

      This should be harmless.
      Vmware will, due to old infrastructure reasons, be using a privileged
      control client to supply GUI layout information rather than obtaining
      it from the device. That control client will be needing access to DRM
      version information.

      ixgbe: X540 thermal warning interrupt not a GPI

      The X540 thermal interrupt (IXGBE_EIMS_TS) is not an SDP, so it
      doesn't need to be enabled in ixgbe_setup_gpie(). In fact the
      value is simply not for the GPIE register at all.

      ixgbe: Fix FCRTH value in VM-to-VM loopback mode

      The 82599 and X540 datasheets require that FCRTH be "set" for Tx
      switching (VM-to-VM loopback) but it did not previously specify what
      the value should be set to. It has now been determined that
      the correct value is RXPBSIZE - (24*1024).

      This setting is also required for later devices.

      ixgbe: Correct several flaws with with DCA setup

      This change does two things. First, it makes it so that we always
      set the relaxed ordering bits related to the DCA registers even if
      DCA is not enabled. Second, it moves the configuration out of the
      ixgbe_down function and into the ixgbe_configure function before
      enabling the Rx and Tx rings. This ensures that DCA is configured
      correctly before starting to process packets.

      Thanks to Alex Duyck for this fix.

      ixgbe: Limit SFP polling rate

      Reduce the frequency of polling for SFP modules. Because the
      service task sometimes runs at high rates, we can poll for
      SFPs too often. When an SFP is not present, the I2C timeouts
      that result are very costly. So, prevent SFP polling from
      being done more than once every two seconds. To reduce latency,
      the poll time is cleared in a couple of cases to permit the
      next service task execution to poll the SFP module.

      Configures the CS4227 correctly for both 1G and 10G operation,
      by moving the code to ixgbe_setup_mac_link_sfp_x550em(). It
      needs to be in this function because we need both the module
      type and the speed, and this is the only function in the init
      flow that knows the speed. In contrast,
      ixgbe_setup_sfp_modules_X550em() does not know the speed, so we
      can't do anything useful here. This is a fundamental difference
      from the previous flow, and is due to the way the CS4227 is

      ipvs: Better derivation of ipvs in ip_vs_tunnel_xmit

      Don't use "net_ipvs(skb_net(skb))" as skb_net is a bad hack.  Instead
      use cp->ipvs and ipvs->net for the net.

      ipvs: Store ipvs not net in struct ip_vs_sync_thread_data

      In practice struct netns_ipvs is as meaningful as struct net and more
      useful as it holds the ipvs specific data.  So store a pointer to
      struct netns_ipvs.

      Update the accesses of tinfo->net to access tinfo->ipvs->net instead.

      drm/mgag200: Fix driver_load error handling

      mgag200_driver_load's error path just calls the drm driver's
      driver_unload op. It isn't safe to call this because it doesn't handle
      things well if driver_load fails somewhere mid way.

      Replace the call to mgag200_driver_unload with a more finegrained
      error handling path.

      drm/mgag200: Fix error handling paths in fbdev driver

      Set up error handling in mgag200_fbdev_init and mgag200fb_create such that
      they release the things they allocate, rather than relying on someone
      calling mga_fbdev_destroy.

      Intel Wired LAN Driver Updates 2015-09-22

      This series contains updates to e1000, e1000e, igbvf, ixgbe, ixgbevf and
      fm10k.

      Jacob provides several updates for fm10k, which cleans up comments and
      most notably a fix for a corner case issue with the PF/VF mailbox code.
      The issue being fm10k_mbx_reset_work clears various states about the
      mailbox, but does not clear the Tx FIFO head/tail pointers.  We also
      are not able to simply clear these pointers, as we would drop
      untransmitted messages without error.  Also adds support for extra debug
      statistics, which provides the ability to see what the PF thinks the
      VF mailboxes look like.

      Don adds support for SFP+ in X550 and support for SCTP flow director
      filters SCTP mask.

      Francois Romieu dusts off the e1000 driver and removes some dead calls
      to e1000_init_eeprom_params().

      Toshiaki Makita provides three patches to enable TSO for stacked VLAN's
      on e1000e, igbvf and ixgbevf.

      Mark provides the first of several ixgbe updates.  First updates the
      driver to accept SFP not present error for all devices, since an SFP
      can still be inserted.  Adds support for SFP insertion interrupt on
      X550EM devices with SPFs.  Adds I2C combined operations on X550EM
      (not X550) devices.  Moved the setting of lan_id to before any I2C
      eeprom access.  Lastly, set the bit bang mode in the hardware when
      performing bit banding I2C operations on X550.

      8139cp: Fix DMA unmapping of transmitted buffers

      The low 16 bits of the 'opts1' field in the TX descriptor are supposed
      to still contain the buffer length when the descriptor is handed back to
      us. In practice, at least on my hardware, they don't. So stash the
      original value of the opts1 field and get the length to unmap from
      there.

      There are other ways we could have worked out the length, but I actually
      want a stash of the opts1 field anyway so that I can dump it alongside
      the contents of the descriptor ring when we suffer a TX timeout.

      8139cp: Do not re-enable RX interrupts in cp_tx_timeout()

      If an RX interrupt was already received but NAPI has not yet run when
      the RX timeout happens, we end up in cp_tx_timeout() with RX interrupts
      already disabled. Blindly re-enabling them will cause an IRQ storm.

      (This is made particularly horrid by the fact that cp_interrupt() always
      returns that it's handled the interrupt, even when it hasn't actually
      done anything. If it didn't do that, the core IRQ code would have
      detected the storm and handled it, I'd have had a clear smoking gun
      backtrace instead of just a spontaneously resetting router, and I'd have
      at *least* two days of my life back. Changing the return value of
      cp_interrupt() will be argued about under separate cover.)

      Unconditionally leave RX interrupts disabled after the reset, and
      schedule NAPI to check the receive ring and re-enable them.

      net: netcp: fix deadlock reported by lockup detector

      A deadlock trace is seen in netcp driver with lockup detector enabled.
      The trace log is provided below for reference. This patch fixes the
      bug by removing the usage of netcp_modules_lock within ndo_ops functions.
      ndo_{open/close/ioctl)() is already called with rtnl_lock held. So there
      is no need to hold another mutex for serialization across processes on
      multiple cores.  So remove use of netcp_modules_lock mutex from these
      ndo ops functions.

      ndo_set_rx_mode() shouldn't be using a mutex as it is called from atomic
      context. In the case of ndo_set_rx_mode(), there can be call to this API
      without rtnl_lock held from an atomic context. As the underlying modules
      are expected to add address to a hardware table, it is to be protected
      across concurrent updates and hence a spin lock is used to synchronize
      the access. Same with ndo_vlan_rx_add_vid() & ndo_vlan_rx_kill_vid().

      Probably the netcp_modules_lock is used to protect the module not being
      removed as part of rmmod. Currently this is not fully implemented and
      assumes the interface is brought down before doing rmmod of modules.
      The support for rmmmod while interface is up is expected in a future
      patch set when additional modules such as pa, qos are added. For now
      all of the tests such as if up/down, reboot, iperf works fine with this
      patch applied.

      Deadlock trace seen with lockup detector enabled is shown below for
      reference.

      The netcp interface is not fully initialized before attach the module
      to the interface. For example, the tx pipe/rx pipe is initialized
      in ethss module as part of attach(). So until this is complete, the

      netcp_core is the first driver that will get initialized and the modules

      net: netcp: ethss: fix error in calling sgmii api with incorrect offset

      On K2HK, sgmii module registers of slave 0 and 1 are mem
      mapped to one contiguous block, while those of slave 2
      and 3 are mapped to another contiguous block.  However,
      on K2E and K2L, sgmii module registers of all slaves are
      mem mapped to one contiguous block.  SGMII APIs expect
      slave 0 sgmii base when API is invoked for slave 0 and 1,
      and slave 2 sgmii base when invoked for other slaves.
      Before this patch, slave 0 sgmii base is always passed to
      sgmii API for K2E regardless which slave is the API invoked
      for.  This patch fixes the problem.

      Merge branch 'bridge_external_fdb_aging'

      Scott Feldman says:

      ====================
      bridge: don't age out externally added FDB entries

      v3: Per davem review: add del_timer_sync on rocker port remove.

      v2: Per Jiri review comment: add BR_DEFAULT_AGEING_TIME to defines

      Siva originally proposed skipping externally added FDB entries in the 
bridge's
      FDB garbage collection func, and moving the ageing of externally added 
entries
      to the port driver/device.  This broke rocker, since rocker didn't have a
      hardware (or software) mechanism for ageing out its learned FDB entries.

      This patchset reintroduces Siva's bridge driver patch to skip externally 
added
      entries and adds support in rocker so rocker can age out its own entries.
      Rocker does this using a software timer similar to the bridge's FDB 
garbage
      collection timer.  Other switchdev devices/drivers can use this software 
timer
      method or program the device to nofity aged-out entries to the driver.

      Updated switchdev.txt documentation to reflect current state-of-the-art.  
This
      removes one more XXX todo comment in switchdev.txt.

      Fix AF_PACKET ABI breakage in 4.2

      Commit 7d82410950aa ("virtio: add explicit big-endian support to memory
      accessors") accidentally changed the virtio_net header used by
      AF_PACKET with PACKET_VNET_HDR from host-endian to big-endian.

      Since virtio_legacy_is_little_endian() is a very long identifier,
      define a vio_le macro and use that throughout the code instead of the
      hard-coded 'false' for little-endian.

      This restores the ABI to match 4.1 and earlier kernels, and makes my

      poll_one_napi and napi_disable.  That is to say, poll_one_napi only tests 
the
      NAPI_STATE_SCHED bit to see if there is work to do during a poll, and as 
such
      the following may happen:

      CPU0                              CPU1
      ndo_tx_timeout                    napi_poll_dev
       napi_disable                      poll_one_napi
        test_and_set_bit (ret 0)
                                  test_bit (ret 1)
         reset adapter             napi_poll_routine

      If the adapter gets a tx timeout without a napi instance scheduled, its 
possible
      for the adapter to think it has exclusive access to the hardware  (as the 
napi
      instance is now scheduled via the napi_disable call), while the netpoll 
code
      thinks there is simply work to do.  The result is parallel hardware access
      leading to corrupt data structures in the driver, and a crash.

      Additionaly, there is another, more critical race between netpoll and
      napi_disable.  The disabled napi state is actually identical to the 
scheduled
      state for a given napi instance.  The implication being that, if a napi 
instance
      is disabled, a netconsole instance would see the napi state of the device 
as
      having been scheduled, and poll it, likely while the driver was dong 
something
      requiring exclusive access.  In the case above, its fairly clear that not 
having
      the rings in a state ready to be polled will cause any number of crashes.

      The fix should be pretty easy.  netpoll uses its own bit to indicate that 
that
      the napi instance is in a state of being serviced by netpoll 
(NAPI_STATE_NPSVC).
      We can just gate disabling on that bit as well as the sched bit.  That 
should
      prevent netpoll from conducting a napi poll if we convert its set bit to a
      test_and_set_bit operation to provide mutual exclusion

      cls_bpf: further limit exec opcodes subset

      Jamal suggested to further limit the currently allowed subset of opcodes
      that may be used by a direct action return code as the intention is not
      to replace the full action engine, but rather to have a minimal set that
      can be used in the fast-path on things like ingress for some features
      that cls_bpf supports.

      Classifiers can, of course, still be chained together that have direct
      action mode with those that have a full exec pass. For more complex
      scenarios that go beyond this minimal set here, the full tcf_exts_exec()
      path must be used.

      cls_bpf: make binding to classid optional

      The binding to a particular classid was so far always mandatory for
      cls_bpf, but it doesn't need to be. Therefore, lift this restriction
      as similarly done in other classifiers.

      Only a couple of qdiscs make use of class from the tcf_result, others
      don't strictly care, so let the user choose his needs (those that read
      out class can handle situations where it could be NULL).

      An explicit check for tcf_unbind_filter() is also not needed here, as
      the previous r->class was 0, so the xchg() will return that and
      therefore a callback to the qdisc's unbind_tcf() is skipped.

      Also, remove tp from cls_bpf_prog_from_efd(), came in as a conflict

      tcp: add proper TS val into RST packets

      RST packets sent on behalf of TCP connections with TS option (RFC 7323
      TCP timestamps) have incorrect TS val (set to 0), but correct TS ecr.

      A > B: Flags [S], seq 0, win 65535, options [mss 1000,nop,nop,TS val 100
      ecr 0], length 0
      B > A: Flags [S.], seq 2444755794, ack 1, win 28960, options [mss
      1460,nop,nop,TS val 7264344 ecr 100], length 0
      A > B: Flags [.], ack 1, win 65535, options [nop,nop,TS val 110 ecr
      7264344], length 0

      B > A: Flags [R.], seq 1, ack 1, win 28960, options [nop,nop,TS val 0
      ecr 110], length 0

      We need to call skb_mstamp_get() to get proper TS val,
      derived from skb->skb_mstamp

      Note that RFC 1323 was advocating to not send TS option in RST segment,
      but RFC 7323 recommends the opposite :

        Once TSopt has been successfully negotiated, that is both <SYN> and
        <SYN,ACK> contain TSopt, the TSopt MUST be sent in every non-<RST>
        segment for the duration of the connection, and SHOULD be sent in an
        <RST> segment (see Section 5.2 for details)

      Note this RFC recommends to send TS val = 0, but we believe it is
      premature : We do not know if all TCP stacks are properly
      handling the receive side :

         When an <RST> segment is
         received, it MUST NOT be subjected to the PAWS check by verifying an
         acceptable value in SEG.TSval, and information from the Timestamps
         option MUST NOT be used to update connection state information.
         SEG.TSecr MAY be used to provide stricter <RST> acceptance checks.

      In 5 years, if/when all TCP stack are RFC 7323 ready, we might consider
      to decide to send TS val = 0, if it buys something.

      drm/amdgpu: sync ce and me with SWITCH_BUFFER(2)

      we used to adopt wait_reg_mem to let CE wait before DE finish page
      updating, but from Tonga+, CE doesn't support wait_reg_mem package so
      this logic no longer works.

      so here is another approach to do same thing:
      Insert two of SWITCH_BUFFER at both front and end of vm_flush can
      guarantee that CE not go further to process IB_const before vm_flush
      done.

      Insert two of SWITCH_BUFFER also works on CI, so remove legency method
      to sync CE and ME

      v2:
      Insert double SWITCH_BUFFER at front of vm flush as well.

      drm/amdgpu: unwind properly in amdgpu_cs_parser_init()

      The amdgpu_cs_parser_init() function doesn't clean up after itself but
      instead the caller uses a free everything function amdgpu_cs_parser_fini()
      on failure.  This style of error handling is often buggy.  In this
      example, we call "drm_free_large(parser->chunks[i].kdata);" when it is
      an unintialized pointer or when "parser->chunks" is NULL.

      I fixed this bug by adding unwind code so that it frees everything that
      it allocates.

      I also mode some other very minor changes:
      1) Renamed "r" to "ret".
      2) Moved the chunk_array allocation to the start of the function.
      3) Removed some initializers which are no longer needed.

      attempt to bind to an interface with fewer bulk endpoints would
      currently lead to an oops.

      Request allocation has been moved to connect_ring, which is called every
      time blkback connects to the frontend (this can happen multiple times 
during
      a blkback instance life cycle). On the other hand, request freeing has not
      been moved, so it's only called when destroying the backend instance. Due 
to
      this mismatch, blkback can allocate the request pool multiple times, 
without
      freeing it.

      In order to fix it, move the freeing of requests to xen_blkif_disconnect 
to
      restore the symmetry between request allocation and freeing.

      drm/i915/bios: handle MIPI Sequence Block v3+ gracefully

      The VBT MIPI Sequence Block version 3 has forward incompatible changes:

      First, the block size in the header has been specified reserved, and the
      actual size is a separate 32-bit value within the block. The current
      find_section() function to will only look at the size in the block
      header, and, depending on what's in that now reserved size field,
      continue looking for other sections in the wrong place.

      Fix this by taking the new block size field into account. This will
      ensure that the lookups for other sections will work properly, as long
      as the new 32-bit size does not go beyond the opregion VBT mailbox size.

      Second, the contents of the block have been completely
      changed. Gracefully refuse parsing the yet unknown data version.

      cxl: Fix lockdep warning while creating afu_err_buff attribute

      Presently a lockdep warning is reported during creation of afu_err_buff
      bin_attribute for the afu. This is caused due to the variable attr.key
      not pointing to a static class key, hence the function lockdep_init_map
      reports this warning:

       BUG: key <some-address> not in .data!

      The patch fixes this issue by calling sysfs_attr_init on the
      attr_eb.attr structure before populating it with the afu_err_buff file
      details. This will populate the attr.key variable with a static class
      key so that lockdep_init_map stops complaining about the lockdep key not
      being static.

      Since we can assume atomic_read() implies a READ_ONCE(), we must only

      READ_ONCE_CTRL() semantics.

      This patch makes sure that atomic_{read,set}() are at least
      {READ,WRITE}_ONCE().

      We already had the 'requirement' that atomic_read() should use
      ACCESS_ONCE(), and most archs had this, but a few were lacking.
      All are now converted to use READ_ONCE().

      And, by a symmetry and general paranoia argument, upgrade atomic_set()
      to use WRITE_ONCE().

      drm/i915: workaround bad DSL readout v3

      On HSW at least (still testing other platforms, but should be harmless
      elsewhere), the DSL reg reads back as 0 when read around vblank start
      time.  This ends up confusing the atomic start/end checking code, since
      it causes the update to appear as if it crossed a frame count boundary.
      Avoid the problem by making sure we don't return scanline_offset from
      the get_crtc_scanline function.  In moving the code there, I add to add
      an additional delay since it could be called and have a legitimate 0
      result for some time (depending on the pixel clock).

      v2: move hsw dsl read hack to get_crtc_scanline (Ville)
      v3: use break instead of goto (Ville)

      arcnet: com20020: Use arcnet_<I/O> routines

      Simplify and make consistent the current uses of inb/outb
      by using the newly introduced arcnet_<I/O> equivalents.

      o Add new #defines for register offsets
        There is an register offset, 8, that is unnamed and used as-is.
      o Remove old #defines that included the ioaddr
      o Remove obfuscating macros by expanding them in-place where appropriate
      o Create static inline com20020_set_subaddress for the SET_SUBADR macro

      There is an unused arcnet config entry CONFIGSA100_CT6001 which added a
      special #define BUS_ALIGN which was introduced but never used in fullhist 
git
      tree commit 22cfce4b82b0 ("[ARCNET]: Fixes.") in Nov 2004 for Linux 
v2.6.10.

      This BUS_ALIGN #define tries to allow 8 bit devices to work on a 16 bit
      bus by aligning addresses to 16 bit boundaries.

      Move this currently unused CONFIG_SA1100_CT6001 BUS_ALIGN macro from
      com20020.h to arcdevice.h.

      perf record: Synthesize COMM event for a command line workload

      When perf creates a new child to profile, the events are enabled on
      exec().  And in this case, it doesn't synthesize any event for the
      child since they'll be generated during exec().  But there's an window
      between the enabling and the event generation.

      It used to be overcome since samples are only in kernel (so we always
      have the map) and the comm is overridden by a later COMM event.
      However it won't work if events are processed and displayed before the
      COMM event overrides like in 'perf script'.  This leads to those early
      samples (like native_write_msr_safe) not having a comm but pid (like
      ':15328').

      So it needs to synthesize COMM event for the child explicitly before
      enabling so that it can have a correct comm.  But at this time, the
      comm will be "perf" since it's not exec-ed yet.

      Committer note:

      tools vm: Fix build due to removal of tools/lib/api/fs/debugfs.h

      There were some changes in how this debugfs mounting helper is

      tools/perf/ to be used by other tools/ living code.

      net: dsa: Fix Marvell Egress Trailer check

      The Marvell Egress rx trailer check must be fixed to
      correctly detect bad bits in the third byte of the
      Eggress trailer as described in the Table 28 of the
      88E6060 datasheet.
      The current code incorrectly omits to check the third
      byte and checks the fourth byte twice.

      lib: fix data race in rhashtable_rehash_one

      rhashtable_rehash_one() uses complex logic to update entry->next field,
      after INIT_RHT_NULLS_HEAD and NULLS_MARKER expansion:

      entry->next = 1 | ((base + off) << 1)

      This can be compiled along the lines of:

      entry->next = base + off
      entry->next <<= 1
      entry->next |= 1

      Which will break concurrent readers.

      NULLS value recomputation is not needed here, so just remove
      the complex logic.

      The data race was found with KernelThreadSanitizer (KTSAN).

      openvswitch: Zero flows on allocation.

      When support for megaflows was introduced, OVS needed to start
      installing flows with a mask applied to them. Since masking is an
      expensive operation, OVS also had an optimization that would only
      take the parts of the flow keys that were covered by a non-zero
      mask. The values stored in the remaining pieces should not matter
      because they are masked out.

      While this works fine for the purposes of matching (which must always
      look at the mask), serialization to netlink can be problematic. Since
      the flow and the mask are serialized separately, the uninitialized
      portions of the flow can be encoded with whatever values happen to be
      present.

      In terms of functionality, this has little effect since these fields
      will be masked out by definition. However, it leaks kernel memory to
      userspace, which is a potential security vulnerability. It is also
      possible that other code paths could look at the masked key and get
      uninitialized data, although this does not currently appear to be an
      issue in practice.

      This removes the mask optimization for flows that are being installed.
      This was always intended to be the case as the mask optimizations were
      really targetting per-packet flow operations.

      net: dsa: actually force the speed on the CPU port

      Commit 54d792f257c6 ("net: dsa: Centralise global and port setup
      code into mv88e6xxx.") merged in the 4.2 merge window broke the link
      speed forcing for the CPU port of Marvell DSA switches.  The original
      code was:

              /* MAC Forcing register: don't force link, speed, duplex
               * or flow control state to any particular values on physical
               * ports, but force the CPU port and all DSA ports to 1000 Mb/s
               * full duplex.
               */
              if (dsa_is_cpu_port(ds, p) || ds->dsa_port_mask & (1 << p))
                      REG_WRITE(addr, 0x01, 0x003e);
              else
                      REG_WRITE(addr, 0x01, 0x0003);

      but the new code does a read-modify-write:

                      reg = _mv88e6xxx_reg_read(ds, REG_PORT(port), 
PORT_PCS_CTRL);
                      if (dsa_is_cpu_port(ds, port) ||
                          ds->dsa_port_mask & (1 << port)) {
                              reg |= PORT_PCS_CTRL_FORCE_LINK |
                                      PORT_PCS_CTRL_LINK_UP |
                                      PORT_PCS_CTRL_DUPLEX_FULL |
                                      PORT_PCS_CTRL_FORCE_DUPLEX;
                              if (mv88e6xxx_6065_family(ds))
                                      reg |= PORT_PCS_CTRL_100;
                              else
                                      reg |= PORT_PCS_CTRL_1000;

      The link speed in the PCS control register is a two bit field.  Forcing
      the link speed in this way doesn't ensure that the bit field is set to
      the correct value - on the hardware I have here, the speed bitfield
      remains set to 0x03, resulting in the speed not being forced to gigabit.

      We must clear both bits before forcing the link speed.

      e1000: remove dead e1000_init_eeprom_params calls

      The device probe method e1000_probe calls e1000_init_eeprom_params
      itself so there's no reason to call it again from e1000_do_write_eeprom
      or e1000_do_read_eeprom.

      The sentence above assumes that e1000_init_eeprom_params is effective.
      e1000_init_eeprom_params depends mostly on hw->mac_type and e1000_probe
      bails out early if it can't set mac_type (see e1000_init_hw_struct, then
      e1000_set_mac_type), qed.

      Btw, if effective, the removed paths would had been deadlock prone when
      e1000_eeprom_spi was set:
      -> e1000_write_eeprom (takes e1000_eeprom_lock)
         -> e1000_do_write_eeprom
            -> e1000_init_eeprom_params
               -> e1000_read_eeprom (takes e1000_eeprom_lock)

      (same narrative with e1000_read_eeprom -> e1000_do_read_eeprom etc.)

      As a final note, the candidate deadlock above can't happen in e1000_probe
      due to the way eeprom->word_size is set / tested.

      fm10k: create "correct" header for the remote end on connect

      When we connect to the mailbox, we insert a fake disconnect header so
      that the code does not see an invalid header and thus instantly error
      every time we bring up the mailbox. However, we incorrectly record the
      tail and head from the local perspective. Since the remote end shouldn't
      have anything for us, add a "create_fake_disconnect_hdr" function which
      inverts the TAIL and HEAD fields. This enables us to connect without any
      errors of either TAIL or HEAD incorrectness, and prevents creating
      extraneous error messages. This is necessary now since mbx_reset_work
      does not actually reset the Tx FIFO head and tail pointers, thus head
      and tail might not be equivalent on a reconnect.

      fm10k: drop transmitted messages in Tx FIFO as part of reset_work

      This patch fixes a corner case issue with the PF/VF mailbox code.
      Currently, fm10k_mbx_reset_work clears various state about the mailbox.
      However, it does not clear the Tx FIFO head/tail pointers. We can't
      simply clear these pointers as we unintentionally drop untransmitted
      messages without error.

      Doing nothing results in a possible phantom re-transmission of messages,
      since we leave tx.head and tx.tail intact, but clear the tx_pulled and
      tail_len values. This means that the PF could continuously re-send a
      message which triggers a reset in the VF. Upon reset, the VF will
      re-receive the same message after a reconnect.

      If we reset the tx.head and tx.tail pointers completely, we end up
      dropping some messages that were pending before connect. This results in
      missing LPORT_MSG_READY bits, and VFs will end up reporting no link.

      However, we can resolve both issues by simply incrementing head to
      account for the already transmitted messages, before we reset tx_pulled.
      We do this via the same logic as fm10k_mbx_head_pull.

      We account for the tail_len which includes all data not yet transmitted,
      once we account for the acked data which means re-reading the HEAD
      variable from the message header. Then, we drop messages until we've
      dropped more than the new tx_pulled value. At this point, resetting
      tail_len and tx_pulled, but not tx.head and tx.tail will result in
      prevention of the phantom message. It also prevents us from dropping
      untransmitted messages upon attempting to Tx into a connect or
      disconnect header.

      ocfs2/dlm: fix deadlock when dispatch assert master

      The order of the following three spinlocks should be:
      dlm_domain_lock < dlm_ctxt->spinlock < dlm_lock_resource->spinlock

      But dlm_dispatch_assert_master() is called while holding
      dlm_ctxt->spinlock and dlm_lock_resource->spinlock, and then it calls
      dlm_grab() which will take dlm_domain_lock.

      Once another thread (for example, dlm_query_join_handler) has already
      taken dlm_domain_lock, and tries to take dlm_ctxt->spinlock deadlock
      happens.

      because we build the test against the installed kernel headers, not the
      in-tree kernel headers.  Re-use "$(TEST_PROGS)" in the clean target
      rather than spelling the executable name twice.  Include <unistd.h>
      rather than the rather specific <asm-generic/unistd.h>.  Include
      <syscall.h> rather than <sys/syscall.h>.  In both cases, the former
      header is located in a standard location and includes the latter.

      x86, efi, kasan: #undef memset/memcpy/memmove per arch

      In not-instrumented code KASAN replaces instrumented memset/memcpy/memmove
      with not-instrumented analogues __memset/__memcpy/__memove.

      However, on x86 the EFI stub is not linked with the kernel.  It uses
      not-instrumented mem*() functions from arch/x86/boot/compressed/string.c

      So we don't replace them with __mem*() variants in EFI stub.

      On ARM64 the EFI stub is linked with the kernel, so we should replace
      mem*() functions with __mem*(), because the EFI stub runs before KASAN
      sets up early shadow.

      So let's move these #undef mem* into arch's asm/efi.h which is also
      included by the EFI stub.

      Also, this will fix the warning in 32-bit build reported by kbuild test
      robot:

        efi-stub-helper.c:599:2: warning: implicit declaration of function

      mm, dax: VMA with vm_ops->pfn_mkwrite wants to be write-notified

      For VM_PFNMAP and VM_MIXEDMAP we use vm_ops->pfn_mkwrite instead of
      vm_ops->page_mkwrite to notify abort write access.  This means we want
      vma->vm_page_prot to be write-protected if the VMA provides this vm_ops.

      A theoretical scenario that will cause these missed events is:

        On writable mapping with vm_ops->pfn_mkwrite, but without
        vm_ops->page_mkwrite: read fault followed by write access to the pfn.
        Writable pte will be set up on read fault and write fault will not be
        generated.

      I found it examining Dave's complaint on generic/080:

        http://lkml.kernel.org/g/20150831233803.GO3902@dastard

      Although I don't think it's the reason.

      It shouldn't be a problem for ext2/ext4 as they provide both pfn_mkwrite
      and page_mkwrite.

      absolutely require wakeall semantics, but we've full control of what we
      insert in the two waitqueue heads of the blocked userfaults.  No
      exclusive waitqueue risks to be inserted into those two waitqueue heads
      so we can as well stick to "nr == 1" of the old code and we can rely
      purely on the fact no waitqueue inserted in one of the two waitqueue
      heads we must enforce as wakeall, has wait->flags WQ_FLAG_EXCLUSIVE set.

      NFS: Skip checking ds_cinfo.buckets when lseg's commit_through_mds is set

      When lseg's commit_through_mds is set, pnfs client always WARN once
      in nfs_direct_select_verf after checking ds_cinfo.nbuckets.

      nfs should use the DS verf except commit_through_mds is set for
      layout segment where nbuckets is zero.

      PCI: Clear IORESOURCE_UNSET when clipping a bridge window

      c770cb4cb505 ("PCI: Mark invalid BARs as unassigned") sets 
IORESOURCE_UNSET
      if we fail to claim a resource.  If we tried to claim a bridge window,
      failed, clipped the window, and tried to claim the clipped window, we
      failed again because of IORESOURCE_UNSET:

        pci_bus 0000:00: root bus resource [mem 0xc0000000-0xffffffff window]
        pci 0000:00:01.0: can't claim BAR 15 [mem 0xbdf00000-0xddefffff 64bit 
pref]: no compatible bridge window
        pci 0000:00:01.0: [mem size 0x20000000 64bit pref] clipped to [mem size 
0x1df00000 64bit pref]
        pci 0000:00:01.0:   bridge window [mem size 0x1df00000 64bit pref]
        pci 0000:00:01.0: can't claim BAR 15 [mem size 0x1df00000 64bit pref]: 
no address assigned

      The 00:01.0 window started as [mem 0xbdf00000-0xddefffff 64bit pref].  
That
      starts before the host bridge window [mem 0xc0000000-0xffffffff window], 
so
      we clipped the 00:01.0 window to [mem 0xc0000000-0xddefffff 64bit pref].
      But we left it marked IORESOURCE_UNSET, so the second claim failed when it
      should have succeeded.

      This means downstream devices will also fail for lack of resources, e.g.,
      in the bugzilla below,

        radeon 0000:01:00.0: Fatal error during GPU init

      Clear IORESOURCE_UNSET when we clip a bridge window.  Also clear
      IORESOURCE_UNSET in our copy of the unclipped window so we can see exactly
      what the original window was and how it now fits inside the upstream
      window.

      x86/nmi/64: Fix a paravirt stack-clobbering bug in the NMI code

      The NMI entry code that switches to the normal kernel stack needs to
      be very careful not to clobber any extra stack slots on the NMI
      stack.  The code is fine under the assumption that SWAPGS is just a
      normal instruction, but that assumption isn't really true.  Use
      SWAPGS_UNSAFE_STACK instead.

      This is part of a fix for some random crashes that Sasha saw.

      x86/paravirt: Replace the paravirt nop with a bona fide empty function

      PARAVIRT_ADJUST_EXCEPTION_FRAME generates this code (using nmi as an
      example, trimmed for readability):

          ff 15 00 00 00 00       callq  *0x0(%rip)        # 2796 <nmi+0x6>
                    2792: R_X86_64_PC32     pv_irq_ops+0x2c

      That's a call through a function pointer to regular C function that
      does nothing on native boots, but that function isn't protected
      against kprobes, isn't marked notrace, and is certainly not
      guaranteed to preserve any registers if the compiler is feeling
      perverse.  This is bad news for a CLBR_NONE operation.

      Of course, if everything works correctly, once paravirt ops are
      patched, it gets nopped out, but what if we hit this code before
      paravirt ops are patched in?  This can potentially cause breakage
      that is very difficult to debug.

      A more subtle failure is possible here, too: if _paravirt_nop uses
      the stack at all (even just to push RBP), it will overwrite the "NMI
      executing" variable if it's called in the NMI prologue.

      The Xen case, perhaps surprisingly, is fine, because it's already
      written in asm.

      Fix all of the cases that default to paravirt_nop (including
      adjust_exception_frame) with a big hammer: replace paravirt_nop with
      an asm function that is just a ret instruction.

      The Xen case may have other problems, so document them.

      This is part of a fix for some random crashes that Sasha saw.

      cifs: use server timestamp for ntlmv2 authentication

      Linux cifs mount with ntlmssp against an Mac OS X (Yosemite
      10.10.5) share fails in case the clocks differ more than +/-2h:

      digest-service: digest-request: od failed with 2 proto=ntlmv2
      digest-service: digest-request: kdc failed with -1561745592 proto=ntlmv2

      Fix this by (re-)using the given server timestamp for the
      ntlmv2 authentication (as Windows 7 does).

      A related problem was also reported earlier by Namjae Jaen (see below):

      Windows machine has extended security feature which refuse to allow
      authentication when there is time difference between server time and
      client time when ntlmv2 negotiation is used. This problem is prevalent
      in embedded enviornment where system time is set to default 1970.

      Modern servers send the server timestamp in the TargetInfo Av_Pair
      structure in the challenge message [see MS-NLMP 2.2.2.1]
      In [MS-NLMP 3.1.5.1.2] it is explicitly mentioned that the client must
      use the server provided timestamp if present OR current time if it is
      not

      ====================
      Netfilter/IPVS updates for net-next

      The following patchset contains Netfilter/IPVS updates for your net-next 
tree
      in this 4.4 development cycle, they are:

      1) Schedule ICMP traffic to IPVS instances, this introduces a new 
schedule_icmp
         proc knob to enable/disable it. By default is off to retain the old
         behaviour. Patchset from Alex Gartrell.

      I'm also including what Alex originally said for the record:

      "The configuration of ipvs at Facebook is relatively straightforward.  All
      ipvs instances bgp advertise a set of VIPs and the network prefers the
      nearest one or uses ECMP in the event of a tie.  For the uninitiated, ECMP
      deterministically and statelessly load balances by hashing the packet
      (usually a 5-tuple of protocol, saddr, daddr, sport, and dport) and using
      that number as an index (basic hash table type logic).

      The problem is that ICMP packets (which contain really important
      information like whether or not an MTU has been exceeded) will get a
      different hash value and may end up at a different ipvs instance.  With no
      information about where to route these packets, they are dropped, creating
      ICMP black holes and breaking Path MTU discovery.  Suddenly, my mom's
      pictures can't load and I'm fielding midday calls that I want nothing to 
do
      with.

      To address this, this patch set introduces the ability to schedule icmp
      packets which is gated by a sysctl net.ipv4.vs.schedule_icmp.  If set to 
0,
      the old behavior is maintained -- otherwise ICMP packets are scheduled."

      2) Add another proc entry to ignore tunneled packets to avoid routing 
loops
         from IPVS, also from Alex.

      3) Fifteen patches from Eric Biederman to:

      * Stop passing nf_hook_ops as parameter to the hook and use the state hook
        object instead all around the netfilter code, so only the private data
        pointer is passed to the registered hook function.

      * Now that we've got state->net, propagate the netns pointer to netfilter 
hook
        clients to avoid its computation over and over again. A good example of 
how
        this has been simplified is the former TEE target (now nf_dup 
infrastructure)
        since it has killed the ugly pick_net() function.

      There's another round of netns updates from Eric Biederman making the 
line. To
      avoid the patchbomb again to almost all the networking mailing list (that 
is 84
      patches) I'd suggest we send you a pull request with no patches or let me 
know
      if you prefer a better way.

      x86/mm: Fix no-change case in try_preserve_large_page()

      try_preserve_large_page() checks if new_prot is the same as
      old_prot.  If so, it simply sets do_split to 0, and returns
      with no-operation.  However, old_prot is set as a 4KB pgprot
      value while new_prot is a large page pgprot value.

      Now that old_prot is initially set from p?d_pgprot() as a
      large page pgprot value, fix it by not overwriting old_prot
      with a 4KB pgprot value.

      x86/mm: Fix __split_large_page() to handle large PAT bit

      __split_large_page() is called from __change_page_attr() to change
      the mapping attribute by splitting a given large page into smaller
      pages.  This function uses pte_pfn() and pte_pgprot() for PUD/PMD,
      which do not handle the large PAT bit properly.

      Fix __split_large_page() by using the corresponding pud/pmd pfn/
      pgprot interfaces.

      Also remove '#ifdef CONFIG_X86_64', which is not necessary.

      slow_virt_to_phys() calls lookup_address() to obtain *pte and

      x86/mm: Fix page table dump to show PAT bit

      /sys/kernel/debug/kernel_page_tables does not show the PAT bit for
      PUD/PMD mappings.  This is because walk_pud_level(), walk_pmd_level()
      and note_page() mask the flags with PTE_FLAGS_MASK, which does not
      cover their PAT bit, _PAGE_PAT_LARGE.

      Fix it by replacing the use of PTE_FLAGS_MASK with p?d_flags(),
      which masks the flags properly.

      Also change to show the PAT bit as "PAT" to be consistent with
      other bits.

      x86/vdso32: Define PGTABLE_LEVELS to 32bit VDSO

      In case of CONFIG_X86_64, vdso32/vclock_gettime.c fakes a 32-bit
      non-PAE kernel configuration by re-defining it to CONFIG_X86_32.
      However, it does not re-define CONFIG_PGTABLE_LEVELS leaving it
      as 4 levels.

      This mismatch leads <asm/pgtable_type.h> to NOT include <asm-generic/
      pgtable-nopud.h> and <asm-generic/pgtable-nopmd.h>, which will cause
      compile errors when a later patch enhances <asm/pgtable_type.h> to
      use PUD_SHIFT and PMD_SHIFT.  These -nopud & -nopmd headers define
      these SHIFTs for the 32-bit non-PAE kernel.

      Fix it by re-defining CONFIG_PGTABLE_LEVELS to 2 levels.

      MIPS: Fix FTLB detection for R6

      R6 removed the Config4.MMUExtDef field, with the low 16 bits only
      allowed to contain FTLB fields, and commit e87569cd6c57 ("MIPS:
      cpu-probe: Fix VTLB/FTLB configuration for R6") updated the probing of
      this field to assume an FTLB is always present for R6.

      However the FTLB may still be absent. The presence of those fields is
      actually specified by the MMU type in the Config.MT field, so use that
      (the new cpu_has_ftlb) to determine whether the FTLB is actually
      present.

      Add cpu_has_ftlb, which specifies that an FTLB is present in addition to
      the VTLB, probed based on whether Config.MT == 4 (rather than 1 for

      This is necessary since MIPS release 6 removes Config4.MMUExtDef, so the

      Btrfs: keep dropped roots in cache until transaction commit

      When dropping a snapshot we need to account for the qgroup changes.  If 
we drop
      the snapshot in all one go then the backref code will fail to find blocks 
from
      the snapshot we dropped since it won't be able to find the root in the fs 
root
      cache.  This can lead to us failing to find refs from other roots that 
pointed
      at blocks in the now deleted root.  To handle this we need to not remove 
the fs
      roots from the cache until after we process the qgroup operations.  Do 
this by
      adding dropped roots to a list on the transaction, and letting the 
transaction
      remove the roots at the same time it drops the commit roots.  This will 
keep all
      of the backref searching code in sync properly, and fixes a problem Mark 
was
      seeing with snapshot delete and qgroups.  Thanks,

      MIPS: BPF: Fix build on pre-R2 little endian CPUs

      The rotr, seh and wsbh instructions have been introduced with the R2
      ISA. Thus the current BPF code fails to build on pre-R2 little endian
      CPUs:

      iommu/io-pgtable-arm: Don't use dma_to_phys()

      In checking whether DMA addresses differ from physical addresses, using
      dma_to_phys() is actually the wrong thing to do, since it may hide any
      DMA offset, which is precisely one of the things we are checking for.
      Simply casting between the two address types, whilst ugly, is in fact
      the appropriate course of action. Further care (and ugliness) is also
      necessary in the comparison to avoid truncation if phys_addr_t and
      dma_addr_t differ in size.

      We can also reject any device with a fixed DMA offset up-front at page
      table creation, leaving the allocation-time check for the more subtle
      cases like bounce buffering due to an incorrect DMA mask.

      Furthermore, we can then fix the hackish KConfig dependency so that
      architectures without a dma_to_phys() implementation may still
      COMPILE_TEST (or even use!) the code. The true dependency is on the
      DMA API, so use the appropriate symbol for that.

      tools lib traceevent: Fix string handling in heterogeneous arch 
environments

      When a trace recorded on a 32-bit device is processed with a 64-bit
      binary, the higher 32-bits of the address need to ignored.

      The lack of this results in the output of the 64-bit pointer
      value to the trace as the 32-bit address lookup fails in find_printk().

      Before:

        burn-1778  [003]   548.600305: bputs:   0xc0046db2s: 2cec5c058d98c

      After:

        burn-1778  [003]   548.600305: bputs:   0xc0046db2s: RT throttling 
activated

      The problem occurs in PRINT_FIELD when the field is recognized as a
      pointer to a string (of the type const char *)

      Heterogeneous architectures cases below can arise and should be handled:

      * Traces recorded using 32-bit addresses processed on a 64-bit machine
      * Traces recorded using 64-bit addresses processed on a 32-bit machine

      futex: Force hot variables into a single cache line

      futex_hash() references two global variables: the base pointer
      futex_queues and the size of the array futex_hashsize. The latter is
      marked __read_mostly, while the former is not, so they are likely to
      end up very far from each other. This means that futex_hash() is
      likely to encounter two cache misses.

      We could mark futex_queues as __read_mostly as well, but that doesn't
      guarantee they'll end up next to each other (and even if they do, they
      may still end up in different cache lines). So put the two variables
      in a small singleton struct with sufficient alignment and mark that as
      __read_mostly.

      irqchip/atmel-aic5: Use per chip mask caches in mask/unmask()

      When masking/unmasking interrupts, mask_cache is updated and used later
      for suspend/resume. Unfortunately, it always was the mask_cache
      associated with the first irq chip which was updated. So when performing
      resume, only irqs 0-31 could be enabled.

      tools lib bpf: Use FEATURE_USER to allow building in the same dir as perf

      When building tools/lib/bpf as part of the tools/perf/ build process,
      which will happend when we introduce a patch wiring that up, we end up
      stomping on the feature detection caching mechanism, that uses a file in
      the output directory (O=) that is shared by libbpf and perf to check if
      something changed from one build to another that requires redoing the
      feature detection process.

      By using the recently introduced FEATURE_USER tools/build/ knob, we can
      avoid that:

      Before, every make invokation would run the feature detection:

        $ make O=/tmp/build/perf -C tools/perf
        make: Entering directory '/home/git/linux/tools/perf'
        Auto-detecting system features:
        ...                         dwarf: [ on  ]
        ...                         glibc: [ on  ]
        <SNIP>
        ...                     get_cpuid: [ on  ]
        ...                           bpf: [ on  ]

          GEN      perf-archive
          GEN      perf-with-kcore

        Auto-detecting system features:
        ...                        libelf: [ on  ]
        ...                           bpf: [ on  ]
        <SNIP>

      After:

        $ make O=/tmp/build/perf -C tools/perf
        make: Entering directory '/home/git/linux/tools/perf'
          BUILD:   Doing 'make -j4' parallel build
        make: Leaving directory '/home/git/linux/tools/perf'
        $

      Because we now have two different feature detection state files:

        $ ls -la /tmp/build/perf/FEATURE-DUMP*
        -rw-rw-r--. 1 acme acme 338 Sep 21 17:25 /tmp/build/perf/FEATURE-DUMP
        -rw-rw-r--. 1 acme acme  33 Sep 21 17:25 
/tmp/build/perf/FEATURE-DUMP.libbpf
        $

      tools build: Allow setting the feature detection user

      We will use the tools/build/ autodetection in the eBPF patchkit
      and it is currently sharing the output directory with perf, that
      also uses the feature detection logic.

      As we keep state in the output directory, so that we can avoid running
      all the tests again, we need to have different filenames for the files
      used in this state, allow doing that via the FEATURE_USER variable, to
      be set alongside the existing FEATURE_{TEST,DISPLAY} variables.

      v2: Fix comment describing the FEATURE_DUMP filename to make sure where
          it is created, precisely at $(OUTPUT)FEATURE-DUMP$(FEATURE_USER).
          Pointed out by Jiri.

      tools lib bpf: Fix up FEATURE_{TESTS,DISPLAY} usage

      When libbpf was introduced it wrongly asked for the "libelf" and "bpf"
      feature tests to be performed (via FEATURE_TESTS), while asking that
      "libbpf", "libelf-mmap", "libelf-getphdrnum" and "bpf" to have the
      result of its respective tests to be displayed (via FEATURE_DISPLAY).

      Due to another recently bug fixed in the tools/build/ infrastructure
      ("tools build: Fixup feature detection display function name") the
      results for the entries in the FEATURE_DISPLAY, for this case, were
      appearing as all succeeding, when two of them (the ones only on the
      DISPLAY) were not even being performed.

      Before:

        $ make -C tools/lib/bpf/
        make: Entering directory '/home/git/linux/tools/lib/bpf'
        Auto-detecting system features:
        ...                        libelf: [ on  ]
        ...             libelf-getphdrnum: [ OFF ]
        ...                   libelf-mmap: [ OFF ]
        ...                           bpf: [ on  ]
        <SNIP>

      After, with FEATURE_TESTS == FEATURE_DISPLAY:

        Auto-detecting system features:
        ...                        libelf: [ on  ]
        ...             libelf-getphdrnum: [ on  ]
        ...                   libelf-mmap: [ on  ]
        ...                           bpf: [ on  ]
        <SNIP>

      I just inverted, so that it tests the four features but displays just
      the libelf and mmap ones, to make it more compact. So it becomes:

        $ make -C tools/lib/bpf/
        make: Entering directory '/home/git/linux/tools/lib/bpf'

        Auto-detecting system features:
        ...                        libelf: [ on  ]

      timers: Fix data race in timer_stats_account_timer()

      timer_stats_account_timer() reads timer->start_site, then checks it
      for NULL and then re-reads it again, while
      timer_stats_timer_clear_start_info() can concurrently reset
      timer->start_site to NULL. This should not lead to crashes, but can
      double number of entries in timer stats as start_site is used during
      comparison, the doubled entries will have unuseful NULL start_site.

      Read timer->start_site only once in timer_stats_account_timer().

      The data race was found with KernelThreadSanitizer (KTSAN).

      mac80211: reset CQM history upon reconfiguration

      The current behavior of notifying CQM events is inconsistent:
      Upon first configuration there is a cqm event with the current
      status according to threshold configured, regardless of signal
      stability.
      When there is reconfiguration no event is sent unless there is
      a significant change to the signal level according to the new
      configuration.

      Since the current reconfiguration behavior might cause missing
      CQM events in case the current signal did not change but is on
      the other side of the new threshold, fix that by resetting the
      stored signal level upon reconfiguration.

       1) the BSS data could be stale
       2) the beacon might not have included all IEs

      The concern (1) doesn't really seem to be relevant any more as
      we time out BSS information after about 30 seconds, and in fact
      the original patch only did the direct probe if the data was
      older than the BSS timeout to begin with. This condition got
      (likely inadvertedly) removed later though.

      Analysing this in more detail shows that since we mostly use
      data from the association response, the only real reason for
      needing the probe response was that the code validates the WMM
      parameters, and those are optional in beacons. As the previous
      patches removed that behaviour, we can now remove the direct
      probe step entirely.

      mac80211: introduce per vif frame registration API

      Currently the cfg80211's frame registration api receives wdev, however
      mac80211 assumes per device filter configuration and ignores wdev.
      Per device filtering is too wasteful, especially for multi-channel
      devices.
      Introduce new per vif frame registration API and use it for probe
      request registrations in ieee80211_mgmt_frame_register()
      Also call directly to ieee80211_configure_filter instead of using a work
      since it is now allowed to sleep in ieee80211_mgmt_frame_register.

      mac80211: process skb_queue while scanning in HW

      Queued frames aren't processed during scan, which results in an inability
      to complete the BA session establishment until the scan ends. Since we
      can't tx frames until the BA agreement setup is complete, it might result
      in a very large latency during scan.
      Fix this by allowing to process queued skbs while scanning in HW. This
      should be ok since the devices which support hw scan should be able
      to handle tx/rx while scanning.
      During SW scan, mac80211 drops any txed frames besides probes and NDPs,
      so it is still needed to delay processing of the queued frames till the
      SW scan is done.

      genirq: Handle force threading of irqs with primary and thread handler

      Force threading of interrupts does not really deal with interrupts
      which are requested with a primary and a threaded handler. The current
      policy is to leave them alone and let the primary handler run in
      interrupt context, but we set the ONESHOT flag for those interrupts as
      well.

      Kohji Okuno debugged a problem with the SDHCI driver where the
      interrupt thread waits for a hardware interrupt to trigger, which can't
      work well because the hardware interrupt is masked due to the ONESHOT
      flag being set. He proposed to set the ONESHOT flag only if the
      interrupt does not provide a thread handler.

      Though that does not work either because these interrupts can be
      shared. So the other interrupt would rightfully get the ONESHOT flag
      set and therefor the same situation would happen again.

      To deal with this proper, we need to force thread the primary handler
      of such interrupts as well. That means that the primary interrupt
      handler is treated as any other primary interrupt handler which is not
      marked IRQF_NO_THREAD. The threaded handler becomes a separate thread
      so the SDHCI flow logic can be handled gracefully.

      The same issue was reported against 4.1-rt.

      async handling, for this usecase we need to implement the netdev
      watchdog. These are all unlikely cases which we drop now and should be
      provided by netdev watchdog.

      We also drop the bit setting for TXNACKREQ at register TXNCON, this is
      not necessary. The TXNCON register should set only once for each frame,
      previous settings doesn't matter.

      mrf24j40: use regmap for register access

      This patch uses the regmap functions for transceiver register settings
      where it's possible. This means everything except the hotpaths like
      receive/transmit handling.

      mrf24j40: add regmap support

      This patch introduce regmap support for short and long address space of
      mrf24j40. It's only possible to use regmap_read/write/update_bits for
      long address range. This is because I added lowlevel bus operation
      because the write operation need to set the 12th bit to mark a register
      write, but regmap only supports to set bits for register write access in
      the first byte. We use other regmap register functions than
      read/write/update_bits, so this should be fine.

      at86rf230: support edge triggered irq

      This patch adds support for edge triggered irq types. We remove the
      locking for irq resources by enable/disable irq and allocate directly
      some heap buffer at isr. We have still a enable/disable irq path but
      this is for level-triggered irq's which need to be disabled until
      spi_async clear the irq line.

      There is usually a little race condition between "irq line cleared" and
      "enable_irq". When in this time a edge triggered irq arrived, we will
      not recognize this interrupt. This case can't happend at at86rf230. The
      reason is that we unmask TRX_END irq's only which indicates a transmit
      or receive completion, which depends on the current state.

      On Transmit:

      TRX_END arrived and transceiver is in TX_ARET_ON state again, in this
      state no other TRX_END can happen until we leave the state.

      On Receive:

      This is protected with the RX_SAFE_MODE bit which leaves the transceiver
      in RX_AACK_BUSY until we readed the framebuffer. In this state no other
      TRX_END can happen.

      Tested with RPi where I first detected issues between edge/level irq's.

      ieee802154: change needed headroom/tailroom

      This patch cleanups needed_headroom, needed_tailroom and hard_header_len
      fields for wpan and lowpan interfaces.

      For wpan interfaces the worst case mac header len should be part of
      needed_headroom, currently this is set as hard_header_len, but
      hard_header_len should be set to the minimum header length which xmit
      call assumes and this is the minimum frame length of 802.15.4.
      The hard_header_len value will check inside send callbacl of AF_PACKET
      raw sockets.

      For lowpan interfaces, if fragmentation isn't needed the skb will
      call dev_hard_header for 802154 layer and queue it afterwards. This
      happens without new skb allocation, so we need the same headroom and
      tailroom lengths like 802154 inside 802154 6lowpan layer. At least we
      assume as minimum header length an ipv6 header size.

      ieee802154: introduce wpan_dev_header_ops

      The current header_ops callback structure of net device are used mostly
      from 802.15.4 upper-layers. Because this callback structure is a very
      generic one, which is also used by e.g. DGRAM AF_PACKET sockets, we
      can't make this callback structure 802.15.4 specific which is currently
      is.

      I saw the smallest "constraint" for calling this callback with
      dev_hard_header/dev_parse_header by AF_PACKET which assign a 8 byte
      array for address void pointers. Currently 802.15.4 specific protocols
      like af802154 and 6LoWPAN will assign the "struct ieee802154_addr" as
      these parameters which is greater than 8 bytes. The current callback
      implementation for header_ops.create assumes always a complete
      "struct ieee802154_addr" which AF_PACKET can't never handled and is
      greater than 8 bytes.

      For that reason we introduce now a "generic" create/parse header_ops
      callback which allows handling with intra-pan extended addresses only.
      This allows a small use-case with AF_PACKET to send "somehow" a valid
      dataframe over DGRAM.

      To keeping the current dev_hard_header behaviour we introduce a similar
      callback structure "wpan_dev_header_ops" which contains 802.15.4 specific
      upper-layer header creation functionality, which can be called by
      wpan_dev_hard_header.

      ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000

      There is a 12MB unused region in our memory map between the vmalloc and
      fixmap areas. This became unused with commit e9da6e9905e6, confirmed
      with commit 64d3b6a3f480.

      We also have a 8MB guard area before the vmalloc area.  With the default
      240MB vmalloc area size and the current VMALLOC_END definition, that
      means the end of low memory ends up at 0xef800000 which is unfortunate
      for 768MB machines where 8MB of RAM is lost to himem.

      Let's move VMALLOC_END to 0xff800000 so the guard area won't chop the
      top of the 768MB low memory area while keeping the default vmalloc area
      size unchanged and still preserving a gap between the vmalloc and fixmap
      areas.

      usb: Use the USB_SS_MULT() macro to get the burst multiplier.

      Bits 1:0 of the bmAttributes are used for the burst multiplier.
      The rest of the bits used to be reserved (zero), but USB3.1 takes bit 7
      into use.

      Use the existing USB_SS_MULT() macro instead to make sure the mult value
      and hence max packet calculations are correct for USB3.1 devices.

      Note that burst multiplier in bmAttributes is zero based and that
      the USB_SS_MULT() macro adds one.

      usb: fixes for v4.3-rc3

      Here's the second pull request for current -rc cycle.

      A few fixes on dummy_hcd which have been around for
      longer than they should be.

      MUSB got a couple fixes, the most important of which
      is a fix to DMA channel teardown on AM335x devices.

      And DWC3 got a minor fix for when using RT-enabled
      kernels.

      Pull cgroup fixes from Tejun Heo:
       "The threadgroup locking changes which went in during 4.2 devel cycle
        added write locking of a percpu_rwsem in cgroup task migration path;
        unfortunately, that involved expedited rcu syncing which turned out to
        be too slow and heavy for certain workloads.  The patchset which is
        dependent on this one didn't get committed during that devel cycle, so
        these two patches can be reverted safely.

        Oleg reworked percpu_rwsem for 4.4 so that the writer path is a lot
        lighter.  The reported issue goes away with Oleg's reworked
        percpu_rwsem and I'll reapply these patches on the for-4.4 branch so
        that they can land together with Oleg's changes"

      Before allowing lockless LISTEN processing, we need to make
      sure to arm the SYN_RECV timer before the req socket is visible
      in hash tables.

      Also, req->rsk_hash should be written before we set rsk_refcnt
      to a non zero value.

      tcp/dccp: fix timewait races in timer handling

      When creating a timewait socket, we need to arm the timer before
      allowing other cpus to find it. The signal allowing cpus to find
      the socket is setting tw_refcnt to non zero value.

      As we set tw_refcnt in __inet_twsk_hashdance(), we therefore need to
      call inet_twsk_schedule() first.

      This also means we need to remove tw_refcnt changes from
      inet_twsk_schedule() and let the caller handle it.

      Note that because we use mod_timer_pinned(), we have the guarantee
      the timer wont expire before we set tw_refcnt as we run in BH context.

      To make things more readable I introduced inet_twsk_reschedule() helper.

      When rearming the timer, we can use mod_timer_pending() to make sure
      we do not rearm a canceled timer.

      Note: This bug can possibly trigger if packets of a flow can hit
      multiple cpus. This does not normally happen, unless flow steering
      is broken somehow. This explains this bug was spotted ~5 months after
      its introduction.

      A similar fix is needed for SYN_RECV sockets in reqsk_queue_hash_req(),
      but will be provided in a separate patch for proper tracking.

      tcp: send loss probe after 1s if no RTT available

      This patch makes TLP to use 1 sec timer by default when RTT is
      not available due to SYN/ACK retransmission or SYN cookies.

      Prior to this change, the lack of RTT prevents TLP so the first
      data packets sent can only be recovered by fast recovery or RTO.
      If the fast recovery fails to trigger the RTO is 3 second when
      SYN/ACK is retransmitted. With this patch we can trigger fast
      recovery in 1sec instead.

      Note that we need to check Fast Open more properly. A Fast Open
      connection could be (accepted then) closed before it receives
      the final ACK of 3WHS so the state is FIN_WAIT_1. Without the
      new check, TLP will retransmit FIN instead of SYN/ACK.

      tcp: usec resolution SYN/ACK RTT

      Currently SYN/ACK RTT is measured in jiffies. For LAN the SYN/ACK
      RTT is often measured as 0ms or sometimes 1ms, which would affect
      RTT estimation and min RTT samping used by some congestion control.

      This patch improves SYN/ACK RTT to be usec resolution if platform
      supports it. While the timestamping of SYN/ACK is done in request
      sock, the RTT measurement is carefully arranged to avoid storing
      another u64 timestamp in tcp_sock.

      For regular handshake w/o SYNACK retransmission, the RTT is sampled
      right after the child socket is created and right before the request
      sock is released (tcp_check_req() in tcp_minisocks.c)

      For Fast Open the child socket is already created when SYN/ACK was
      sent, the RTT is sampled in tcp_rcv_state_process() after processing
      the final ACK an right before the request socket is released.

      If the SYN/ACK was retransmistted or SYN-cookie was used, we rely
      on TCP timestamps to measure the RTT. The sample is taken at the
      same place in tcp_rcv_state_process() after the timestamp values
      are validated in tcp_validate_incoming(). Note that we do not store
      TS echo value in request_sock for SYN-cookies, because the value
      is already stored in tp->rx_opt used by tcp_ack_update_rtt().

      One side benefit is that the RTT measurement now happens before
      initializing congestion control (of the passive side). Therefore
      the congestion control can use the SYN/ACK RTT.

      usbnet: New driver for QinHeng CH9200 devices

      There's a bunch of cheap USB 10/100 devices based on QinHeng chipsets. The
      vendor driver supports the CH9100 and CH9200 devices, but the majority of
      the code is of the if (ch9100) {} else {} form, with the most significant
      difference being that CH9200 provides a real MII interface but CH9100 
fakes
      one with a bunch of global variables and magic commands. I don't have a
      CH9100, so it's probably better if someone who does provides an 
independent
      driver for it. In any case, this is a lightly cleaned up version of the
      vendor driver with all the CH9100 code dropped.

      qeth: add layer 2 RX/TX checksum offloading

      Checksum offloading for send and receive is already
      supported for layer 3 (IP layer). This patch
      adds support for RX and TX hardware checksum offloading
      for layer 2 (MAC layer). The hardware calculates the checksum
      for IP UDP and TCP packets.

      This patch moves the hardware checksum offloading setup
      to the set of common functions in qeth_core_main.c.
      Layer 2 and layer 3 now simply call the same common functions.

      Also note that TX checksum offloading is always enabled.
      The device driver relies on the TCP/IP stack to make use of
      this feature.

      perf probe: Fix a segfault when removing uprobe events

      Fix a segfault bug and a small mistake in perf probe -d.

      Since the "ulist" in perf_del_probe_events is never initialized,
      strlist__add(ulist, *) always causes a segfault when removing
      uprobe events by perf probe -d.

      Also, the "str" local variable is never released if fail to
      allocate the "klist". This fixes it too.

      This has been introduced by the commit e607f1426b58 ("perf probe:
      Print deleted events in cmd_probe()").

      This means that the inode had non-zero "outstanding extents" during
      eviction. This occurs because, during direct I/O a task which successfully
      used up its reserved data space would set BTRFS_INODE_DIO_READY bit and 
does
      not clear the bit after finishing the DIO write. A future DIO write could
      actually fail and the unused reserve space won't be freed because of the
      previously set BTRFS_INODE_DIO_READY bit.

      Clearing the BTRFS_INODE_DIO_READY bit in btrfs_direct_IO() caused the
      following issue,

      Hence this commit introduces "struct btrfs_dio_data" to track the usage of
      reserved data space. The remaining unused "reserve space" can now be freed

      mtd: nand: sunxi: fix OOB handling in ->write_xxx() functions

      The USER_DATA register cannot be accessed using byte accessors on A13
      SoCs, thus triggering a bug when using memcpy_toio on this register.
      Declare an helper macros to convert an OOB buffer into a suitable
      USER_DATA value and vice-versa.

      This patch also fixes an error in the oob_required logic (some OOB data
      are not written even if the user required it) by removing the
      oob_required condition, which is perfectly valid since the core already
      fill ->oob_poi with FFs when oob_required is false.

      usb: gadget: dummy_hcd: in transfer(), return data sent, not limit

      dummy_timer uses transfer() to update transfer limit. However,
      limit passed to dummy_timer changes depending on transfer type,
      so the actual limit is overwritten.

      This can cause unpredictably slow / fast bulk transfers when
      coupled with control / interrupt transfers.

      Fix by returning actual amount of data sent in transfer() and
      substracting from total.

      usb: gadget: dummy_hcd: emulate sending zlp in packet logic

      currently, when a zlp flag is set and an urb/usb_request
      buffer is filled without a short packet, transfer() leaves
      its status at -EINPROGRESS and does not rescan for short
      packet.

      In a scenario where ep.maxpacket bytes are copied,
      URB_ZERO_PACKET is set, urb buffer is filled and usb_request
      buffer is not, transfer() returns with an urb with
      -EINPROGRESS status, which dummy_hcd treats as incomplete
      transfer.

      Check for zlp and rescan appropriately.

      Input: elan_i2c - don't require known iap version

      The Asus X456UA has an ELAN1000 touchpad with IAP version 0xe.  This is
      unknown to elan_get_fwinfo() so driver probe fails and I am left with an
      unusable touchpad.

      However, the fwinfo is not required for general driver usage, it is only
      needed if the user decides to upload new firmware.

      Adjust the driver so that we do not abort probe when we encounter
      unexpected IAP version, but rather warn user that firmware update feature
      of the driver will not work.

      crypto: marvell - properly handle CRYPTO_TFM_REQ_MAY_BACKLOG-flagged 
requests

      The mv_cesa_queue_req() function calls crypto_enqueue_request() to
      enqueue a request. In the normal case (i.e the queue isn't full), this
      function returns -EINPROGRESS. The current Marvell CESA crypto driver
      takes this into account and cleans up the request only if an error
      occured, i.e if the return value is not -EINPROGRESS.

      Unfortunately this causes problems with
      CRYPTO_TFM_REQ_MAY_BACKLOG-flagged requests. When such a request is
      passed to crypto_enqueue_request() and the queue is full,
      crypto_enqueue_request() will return -EBUSY, but will keep the request
      enqueued nonetheless. This situation was not properly handled by the
      Marvell CESA driver, which was anyway cleaning up the request in such
      a situation. When later on the request was taken out of the backlog
      and actually processed, a kernel crash occured due to the internal
      driver data structures for this structure having been cleaned up.

      To avoid this situation, this commit adds a
      mv_cesa_req_needs_cleanup() helper function which indicates if the
      request needs to be cleaned up or not after a call to
      crypto_enqueue_request(). This helper allows to do the cleanup only in
      the appropriate cases, and all call sites of mv_cesa_queue_req() are
      fixed to use this new helper function.

      hwrng: core - Simplify RNG switching from sysfs

      If we attempt to use sysfs to change the current RNG in the usual
      way i.e. issuing something like:

      `echo 8a8a000.rng > /sys/devices/virtual/misc/hw_random/rng_current`

      ... it will fail because the code doesn't currently take the '\n'
      into consideration.  Well, now it does.

      hwrng: Kconfig - Fix device node name reference /dev/hw_random => 
/dev/hwrng

      In April 2009, commit d405640 ("Driver Core: misc: add node name support
      for misc devices.") inadvertently changed the device node name from
      /dev/hw_random to /dev/hwrng.  Since 6 years has passed since the change
      it seems unpractical to change it back, as this node name is probably
      considered ABI by now.  So instead, we'll just change the Kconfig help
      to match the current situation.

      NB: It looks like rng-tools have already been updated.

      Commit a1efb01feca597b ("jump_label, locking/static_keys: Rename

      introduced the definition of JUMP_TYPE_MASK in

      As JUMP_TYPE_MASK definition in desc.h is never used, we can safely remove

      can: flexcan: flexcan_chip_start(): cleanup writing of reg_mcr

      This patch changes the order the individual bits of the mcr register in
      flexcan_chip_start() are or'ed together to match the datasheet. The inline
      documentation is adjusted accordingly.

      netlink: Fix autobind race condition that leads to zero port ID

      The commit c0bb07df7d981e4091432754e30c9c720e2c0c78 ("netlink:
      Reset portid after netlink_insert failure") introduced a race
      condition where if two threads try to autobind the same socket
      one of them may end up with a zero port ID.  This led to kernel
      deadlocks that were observed by multiple people.

      This patch reverts that commit and instead fixes it by introducing
      a separte rhash_portid variable so that the real portid is only set
      after the socket has been successfully hashed.

      macvtap: fix TUNSETSNDBUF values > 64k

      Upon TUNSETSNDBUF,  macvtap reads the requested sndbuf size into
      a local variable u.
      commit 39ec7de7092b ("macvtap: fix uninitialized access on
      TUNSETIFF") changed its type to u16 (which is the right thing to
      do for all other macvtap ioctls), breaking all values > 64k.

      The value of TUNSETSNDBUF is actually a signed 32 bit integer, so
      the right thing to do is to read it into an int.

      These have roughly the same purpose as the SMRR, which we do not need

      iptunnel: make rx/tx bytes counters consistent

      This was already done a long time ago in

      Netfilter fixes for net

      The following patch contains Netfilter fixes for your net tree, they are:

      1) nf_log_unregister() should only set to NULL the logger that is being
         unregistered, instead of everything else. Patch from Florian Westphal.

      2) Fix a crash when accessing physoutdev from PREROUTING in br_netfilter.
         This is partially reverting the patch to shrink nf_bridge_info to 32 
bytes.
         Also from Florian.

      3) Use existing match/target extensions in the internal nft_compat 
extension
         lists when the extension is family unspecific (ie. NFPROTO_UNSPEC).

      4) Wait for rcu grace period before leaving nf_log_unregister().

      This reverts commit 1298267b548a78840bd4b3e030993ff8747ca5e6.

      That commit claim that the Vitesse VSC8641 is compatible with Vitesse
      82xx. But this is not true. It seems that all the registers used
      in Vitesse phy driver are not compatible between 8641 and 82xx.
      It does cause malfunction of the Ethernet on p1010rdb-pa board.
      So we definitely need a rework in order to support the 8641 phy
      in this driver.

      Intel Wired LAN Driver Updates 2015-09-17

      This series contains updates to i40e and i40evf.

      Shannon provides updates to i40e and i40evf to resolve an issue with the
      nvmupdate utility.  First renames a variable name to reduce confusion and
      to differentiate it from the actual user variable.  Then added the ability
      to save the admin queue write back descriptor if a caller supplies a
      buffer for it to be saved into.  Added a new GetStatus command so that
      the NVM update tool can query the current status instead of doing fake
      write requests to probe for readiness.  Added wait states to the NVM
      update state machine to signify when waiting for an update operation to
      finish, whether we are in the middle of a set of write operations, or we
      are now idle but waiting.  Then added a facility to run admin queue
      commands through the NVM update utility in order to allow the update
      tools to interact with the firmware and do special commands needed for
      updates and configuration changes.  Also added a facility to recover the
      result of a previously run admin queue command.

      net: Fix behaviour of unreachable, blackhole and prohibit routes

      Man page of ip-route(8) says following about route types:

        unreachable - these destinations are unreachable.  Packets are disâ??
        carded and the ICMP message host unreachable is generated.  The local
        senders get an EHOSTUNREACH error.

        blackhole - these destinations are unreachable.  Packets are disâ??
        carded silently.  The local senders get an EINVAL error.

        prohibit - these destinations are unreachable.  Packets are discarded
        and the ICMP message communication administratively prohibited is
        generated.  The local senders get an EACCES error.

      In the inet6 address family, this was correct, except the local senders
      got ENETUNREACH error instead of EHOSTUNREACH in case of unreachable 
route.
      In the inet address family, all three route types generated ICMP message
      net unreachable, and the local senders got ENETUNREACH error.

      In both address families all three route types now behave consistently
      with documentation.

      net: add Hisilicon Network Subsystem basic ethernet support

      This is to add basic ethernet support for HNS. It is one of the way to
      use the HNS acceleration engine. But most of the decoding/encoding
      capability of the AE cannot be used in this way.

      This submit contains the basic feature as a ethernet driver. More will
      be added later.

      net: add Hisilicon Network Subsystem support (config and documents)

      The Hisilicon Network Subsystem is a long term evolution IP which is
      supposed to be used in Hisilicon ICT SoC. The IP, which is called hns
      for short, is a TCP/IP acceleration engine, which can directly decode
      TCP/IP stream and distribute them to different ring buffers.

      HNS can be configured to work on different mode for different scenario.
      This patch make use only some of the mode to make it as standard
      ethernet NIC. The other mode will be added soon.

      The whole function has 4 kernel sub-modules:

      hnae: the HNS acceleration engine framework. It provides a abstract
      interface between the engine and the upper layers which make use of the
      engine by ring buffer.

      hns_enet_drv: a standard ethernet driver that base on the ring buffer.

      hns_dsaf: one of the implementation of HNS acceleration engine, which is
      applied on Hililicon hip05, Hi1610 and other later-on SoCs

      hns_mdio: the mdio control to the PHY, used by acceleration engine

      rcu: Make ->cpu_no_qs be a union for aggregate OR

      This commit converts the rcu_data structure's ->cpu_no_qs field
      to a union.  The bytewise side of this union allows individual access
      to indications as to whether this CPU needs to find a quiescent state
      for a normal (.norm) and/or expedited (.exp) grace period.  The setwise
      side of the union allows testing whether or not a quiescent state is
      needed at all, for either type of grace period.

      For now, only .norm is used.  A later commit will introduce the expedited
      usage.

      rcu: Rename qs_pending to core_needs_qs

      An upcoming commit needs to invert the sense of the ->passed_quiesce
      rcu_data structure field, so this commit is taking this opportunity
      to clarify things a bit by renaming ->qs_pending to ->core_needs_qs.

      So if !rdp->core_needs_qs, then this CPU need not concern itself with
      quiescent states, in particular, it need not acquire its leaf rcu_node
      structure's ->lock to check.  Otherwise, it needs to report the next
      quiescent state.

      rcu: Move synchronize_sched_expedited() to combining tree

      Currently, synchronize_sched_expedited() uses a single global counter
      to track the number of remaining context switches that the current
      expedited grace period must wait on.  This is problematic on large
      systems, where the resulting memory contention can be pathological.
      This commit therefore makes synchronize_sched_expedited() instead use
      the combining tree in the same manner as synchronize_rcu_expedited(),
      keeping memory contention down to a dull roar.

      This commit creates a temporary function sync_sched_exp_select_cpus()
      that is very similar to sync_rcu_exp_select_cpus().  A later commit
      will consolidate these two functions, which becomes possible when
      synchronize_sched_expedited() switches from stop_one_cpu_nowait() to
      smp_call_function_single().

      rcu: Use single-stage IPI algorithm for RCU expedited grace period

      The current preemptible-RCU expedited grace-period algorithm invokes
      synchronize_sched_expedited() to enqueue all tasks currently running
      in a preemptible-RCU read-side critical section, then waits for all the
      ->blkd_tasks lists to drain.  This works, but results in both an IPI and
      a double context switch even on CPUs that do not happen to be running
      in a preemptible RCU read-side critical section.

      This commit implements a new algorithm that causes less OS jitter.
      This new algorithm IPIs all online CPUs that are not idle (from an
      RCU perspective), but refrains from self-IPIs.  If a CPU receiving
      this IPI is not in a preemptible RCU read-side critical section (or
      is just now exiting one), it pushes quiescence up the rcu_node tree,
      otherwise, it sets a flag that will be handled by the upcoming outermost
      rcu_read_unlock(), which will then push quiescence up the tree.

      The expedited grace period must of course wait on any pre-existing blocked
      readers, and newly blocked readers must be queued carefully based on
      the state of both the normal and the expedited grace periods.  This
      new queueing approach also avoids the need to update boost state,
      courtesy of the fact that blocked tasks are no longer ever migrated to
      the root rcu_node structure.

      rcu: Use rsp->expedited_wq instead of sync_rcu_preempt_exp_wq

      Now that there is an ->expedited_wq waitqueue in each rcu_state structure,
      there is no need for the sync_rcu_preempt_exp_wq global variable.  This
      commit therefore substitutes ->expedited_wq for sync_rcu_preempt_exp_wq.

      start of each expedited grace period.

      rcu: Suppress lockdep false positive for rcp->exp_funnel_mutex

      In kernels built with CONFIG_PREEMPT=y, synchronize_rcu_expedited()
      invokes synchronize_sched_expedited() while holding RCU-preempt's
      root rcu_node structure's ->exp_funnel_mutex, which is acquired after
      the rcu_data structure's ->exp_funnel_mutex.  The first thing that
      synchronize_sched_expedited() will do is acquire RCU-sched's rcu_data
      structure's ->exp_funnel_mutex.   There is no danger of an actual deadlock
      because the locking order is always from RCU-preempt's expedited mutexes
      to those of RCU-sched.  Unfortunately, lockdep considers both rcu_data
      structures' ->exp_funnel_mutex to be in the same lock class and therefore
      reports a deadlock cycle.

      This commit silences this false positive by placing RCU-sched's rcu_data
      structures' ->exp_funnel_mutex locks into their own lock class.

      rcu: Change _wait_rcu_gp() to work around GCC bug 67055

      NFSv4: Recovery of recalled read delegations is broken

      When a read delegation is being recalled, and we're reclaiming the
      cached opens, we need to make sure that we only reclaim read-only
      modes.
      A previous attempt to do this, relied on retrieving the delegation
      type from the nfs4_opendata structure. Unfortunately, as Kinglong
      pointed out, this field can only be set when performing reboot recovery.

      Furthermore, if we call nfs4_open_recover(), then we end up clobbering
      the state->flags for all modes that we're not recovering...

      The fix is to have the delegation recall code pass this information
      to the recovery call, and then refactor the recovery code so that
      nfs4_open_delegation_recall() does not need to call nfs4_open_recover().

      Access to the kvm->buses (like with the kvm_io_bus_read() and -write()

      KVM: PPC: Book3S HV: Fix handling of interrupted VCPUs

      This fixes a bug which results in stale vcore pointers being left in
      the per-cpu preempted vcore lists when a VM is destroyed.  The result
      of the stale vcore pointers is usually either a crash or a lockup
      inside collect_piggybacks() when another VM is run.  A typical
      lockup message looks like:

      The bug is that kvmppc_run_vcpu does not correctly handle the case
      where a vcpu task receives a signal while its guest vcpu is executing
      in the guest as a result of being piggy-backed onto the execution of
      another vcore.  In that case we need to wait for the vcpu to finish
      executing inside the guest, and then remove this vcore from the
      preempted vcores list.  That way, we avoid leaving this vcpu's vcore
      on the preempted vcores list when the vcpu gets interrupted.

      thunderbolt: Allow loading of module on recent Apple MacBooks with 
thunderbolt 2 controller

      The pci device ids listed in the thunderbolt driver are to restrictive,
      which prevents the driver from being loaded on recent Apple MacBooks
      using a thunderbolt 2 controller. In particular this prevented any
      hot-plugging functionality for thunderbolt based ethernet dongles
      (i.e. Apples thunderbolt gigabit ethernet broadcom tg3 based dongle
      Model A1433 EMC 2590).

      Changing the subvendor and subdevice to PCI_ANY_ID the thunderbolt driver
      loads and binds to the pci device 07:00.0 System peripheral:
      Intel Corporation Device 156c which is the thunderbolt 2 controller on
      the MacBookPro12,1.

      Successfully tested on MacBookPro12,1. With the patch the thunderbolt
      module gets now loaded on boot. And it provides hot-plugging support both
      for a cold-plugged and a warm-plugged ethernet dongle.

      NFS: Fix an infinite loop when layoutget fail with BAD_STATEID

      If layouget fail with BAD_STATEID, restart should not using the old 
stateid.
      But, nfs client choose the layout stateid at first, and then the open 
stateid.

      To avoid the infinite loop of using bad stateid for layoutget,
      this patch sets the layout flag'ss NFS_LAYOUT_INVALID_STID bit to
      skip choosing the bad layout stateid.

      thermal: power_allocator: exit early if there are no cooling devices

      Don't waste cycles in the power allocator governor's throttle function
      if there are no cooling devices and exit early.

      This commit doesn't change any functionality, but should provide better
      performance for the odd case of a thermal zone with trip points but
      without cooling devices.

         - Fix a CONFIG_ prefix bug in one of the ACPI drivers and make the
           ACPI subsystem use IS_ENABLED() instead of #ifdefs in function

      fs-writeback: unplug before cond_resched in writeback_sb_inodes

      Commit 505a666ee3fc ("writeback: plug writeback in wb_writeback() and
      writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes,
      which increases the merge rate when relatively contiguous small files
      are written by the filesystem.  It helps both on flash and spindles.

      For an fs_mark workload creating 4K files in parallel across 8 drives,
      this commit improves performance ~9% more by unplugging before calling
      cond_resched().  cond_resched() doesn't trigger an implicit unplug, so
      explicitly getting the IO down to the device before scheduling reduces
      latencies for anyone waiting on clean pages.

      It also cuts down on how often we use kblockd to unplug, which means
      less work bouncing from one workqueue to another.

      Many more details about how we got here:

      regmap: debugfs: Don't bother actually printing when calculating max 
length

      The in kernel snprintf() will conveniently return the actual length of
      the printed string even if not given an output beffer at all so just do
      that rather than relying on the user to pass in a suitable buffer,
      ensuring that we don't need to worry if the buffer was truncated due to
      the size of the buffer passed in.

      If a read is attempted which is smaller than the line length then we may

      move some of the calculation to be additions on the right hand side

      mm: fix type cast in __pfn_to_phys()

      The various definitions of __pfn_to_phys() have been consolidated to
      use a generic macro in include/asm-generic/memory_model.h. This hit
      mainline in the form of 012dcef3f058 "mm: move __phys_to_pfn and
      __pfn_to_phys to asm/generic/memory_model.h". When the generic macro
      was implemented the type cast to phys_addr_t was dropped which caused
      boot regressions on ARM platforms with more than 4GB of memory and
      LPAE enabled.

      It was suggested to use PFN_PHYS() defined in include/linux/pfn.h
      as provides the correct logic and avoids further duplication.

      We are more likely to access the fields in nf_hook_state over the

      netfilter: ebtables: Simplify the arguments to ebt_do_table

      Nearly everything thing of interest to ebt_do_table is already present
      in nf_hook_state.  Simplify ebt_do_table by just passing in the skb,
      nf_hook_state, and the table.  This make the code easier to read and
      maintenance easier.

      To support this create an nf_hook_state on the stack in ebt_broute
      (the only caller without a nf_hook_state already available).  This new
      nf_hook_state adds no new computations to ebt_broute, but does use a
      few more bytes of stack.

      perf record: Avoid infinite loop at buildid processing with no samples

      If a session contains no events, we can get stuck in an infinite loop in
      __perf_session__process_events, with a non-zero file_size and 
data_offset, but
      a zero data_size.

      In this case, we can mmap the entirety of the file (consisting of the 
file and
      attribute headers), and fetch_mmaped_event will correctly refuse to read 
any
      (unmapped and non-existent) event headers. This causes
      __perf_session__process_events to unmap the file and retry with the exact 
same
      parameters, getting stuck in an infinite loop.

      This has been observed to result in an exit-time hang when counting
      rare/unschedulable events with perf record, and can be triggered 
artificially
      with the script below:

        ----
        #!/bin/sh
        printf "REPRO: launching perf\n";
        ./perf record -e software/config=9/ sleep 1 &
        PERF_PID=$!;
        sleep 0.002;
        kill -2 $PERF_PID;
        printf "REPRO: waiting for perf (%d) to exit...\n" "$PERF_PID";
        wait $PERF_PID;
        printf "REPRO: perf exited\n";
        ----

      To avoid this, have __perf_session__process_events bail out early when
      the file has no data (i.e. it has no events).

      Commiter note:

      I only managed to reproduce this when setting
      /proc/sys/kernel/kptr_restrict to '1' and changing the code to
      purposefully not process any samples and no synthesized samples, i.e.
      kptr_restrict prevents 'record' from synthesizing the kernel mmaps for
      vmlinux + modules and since it is a workload started from perf, we don't
      synthesize mmap/comm records for existing threads.

      Adrian Hunter managed to reproduce it in his environment tho.

      IB/hfi: Properly set permissions for user device files

      Some of the device files are required to be user accessible for PSM while
      most should remain accessible only by root.

      Add a parameter to hfi1_cdev_init which controls if the user should have 
access
      to this device which places it in a different class with the appropriate
      devnode callback.

      In addition set the devnode call back for the existing class to be a bit 
more
      explicit for those permissions.

      Finally remove the unnecessary null check before class_destroy

      I added spaces around operators so it matches kernel style because

      kvm: svm: reset mmu on VCPU reset

      When INIT/SIPI sequence is sent to VCPU which before that
      was in use by OS, VMRUN might fail with:

       EFER=0000000000000000

      with corresponding SVM error:
       KVM: FAILED VMRUN WITH VMCB:
       [...]
       cpl:            0                efer:         0000000000001000

       [...]

      What happens is that VCPU state right after offlinig:
      CR0: 0x80050033  EFER: 0xd01  CR4: 0x7e0
        -> long mode with CR3 pointing to longmode page tables

      and when VCPU gets INIT/SIPI following transition happens
      CR0: 0 -> 0x60000010 EFER: 0x0  CR4: 0x7e0
        -> paging disabled with stale CR3

      However SVM under the hood puts VCPU in Paged Real Mode*
      which effectively translates CR0 0x60000010 -> 80010010 after

         svm_vcpu_reset()
             -> init_vmcb()
                 -> kvm_set_cr0()
                     -> svm_set_cr0()

      but from  kvm_set_cr0() perspective CR0: 0 -> 0x60000010
      only caching bits are changed and
      commit d81135a57aa6
       ("KVM: x86: do not reset mmu if CR0.CD and CR0.NW are changed")'
      regressed svm_vcpu_reset() which relied on MMU being reset.

      As result VMRUN after svm_vcpu_reset() tries to run
      VCPU in Paged Real Mode with stale MMU context (longmode page tables),
      which causes some AMD CPUs** to bail out with VMEXIT_INVALID.

      Fix issue by unconditionally resetting MMU context
      at init_vmcb() time.

      sched: access local runqueue directly in single_task_running

      Commit 2ee507c47293 ("sched: Add function single_task_running to let a 
task
      check if it is the only task running on a cpu") referenced the current
      runqueue with the smp_processor_id.  When CONFIG_DEBUG_PREEMPT is enabled,
      that is only allowed if preemption is disabled or the currrent task is
      bound to the local cpu (e.g. kernel worker).

      With commit f78195129963 ("kvm: add halt_poll_ns module parameter") KVM
      calls single_task_running. If CONFIG_DEBUG_PREEMPT is enabled that
      generates a lot of kernel messages.

      To avoid adding preemption in that cases, as it would limit the 
usefulness,
      we change single_task_running to access directly the cpu local runqueue.

      s390/compat: remove superfluous compat wrappers

      A couple of compat wrapper functions are simply trampolines to the real
      system call. This happened because the compat wrapper defines will only
      sign and zero extend system call parameters which are of different size
      on s390/s390x (longs and pointers).

      Bluetooth: Fix reporting incorrect EIR in device found mgmt event

      Some remote devices (ie Gigaset G-Tag) misbehave with ADV data length.
      This can lead to incorrect EIR format in device found event when
      ADV_DATA and SCAN_RSP are merged (terminator field before SCAN_RSP
      part).

      Fix this by inspecting ADV_DATA and correct its length if terminator
      is found.

      x86/asm/entry/32, selftests: Add 'test_syscall_vdso' test

      This new test checks that all x86 registers are preserved across
      32-bit syscalls. It tests syscalls through VDSO (if available)
      and through INT 0x80, normally and under ptrace.

      If kernel is a 64-bit one, high registers (r8..r15) are poisoned
      before the syscall is called and are checked afterwards.

      They must be either preserved, or cleared to zero (but r11 is
      special); r12..15 must be preserved for INT 0x80.

      EFLAGS is checked for changes too, but change there is not
      considered to be a bug (paravirt kernels do not preserve
      arithmetic flags).

      Run-tested on 64-bit kernel:

      ath9k_htc: introduce support for different fw versions

      Current kernel support only one fw name with theoretically only one
      fw version located in â??firmware/htc_[9271|7010].fwâ??. Which is ok so 
far we
      have only one fw version (1.3). After we realised new fw 1.4, we faced
      compatibility problem which was decided to solve by firmware name and
      location:
      - new firmware is located now in
        firmware/ath9k_htc/htc_[9271|7010]-1.4.0.fw
      - old version 1.3 should be on old place, so old kernel have no issues
        with it.
      - new kernels including this patch should be able to try different
        supported (min..max) fw version.
      - new kernel should be able to support old fw location too. At least for
        now.

      At same time this patch will add new module option which should allow user
      to play with development  fw version without replacing stable one. If user
      will set â??ath9k_htc use_dev_fw=1â?? module will try to find
      firmware/ath9k_htc/htc_[9271|7010]-1.dev.0.fw first and if it fails, use
      stable version: for example...1.4.0.fw.

      sched/numa: Limit the amount of virtual memory scanned in task_numa_work()

      Currently task_numa_work() scans up to numa_balancing_scan_size_mb worth
      of memory per invocation, but only counts memory areas that have at
      least one PTE that is still present and not marked for numa hint faulting.

      It will skip over arbitarily large amounts of memory that are either
      unused, full of swap ptes, or full of PTEs that were already marked
      for NUMA hint faults but have not been faulted on yet.

      This can cause excessive amounts of CPU use, due to there being
      essentially no upper limit on the scan rate of very large processes
      that are not yet in a phase where they are actively accessing old
      memory pages (eg. they are still initializing their data).

      Avoid that problem by placing an upper limit on the amount of virtual
      memory that task_numa_work() scans in each invocation. This can be a
      higher limit than "pages", to ensure the task still skips over unused
      areas fairly quickly.

      While we are here, also fix the "nr_pte_updates" logic, so it only
      counts page ranges with ptes in them.

      perf: Fix races in computing the header sizes

      There are two races with the current code:

       - Another event can join the group and compute a larger header_size
         concurrently, if the smaller store wins we'll have an incorrect
         header_size set.

       - We compute the header_size after the event becomes active,
         therefore its possible to use the size before its computed.

      Remedy the first by moving the computation inside the ctx::mutex lock,
      and the second by placing it _before_ perf_install_in_context().

      perf: Fix u16 overflows

      Vince reported that its possible to overflow the various size fields
      and get weird stuff if you stick too many events in a group.

      Put a lid on this by requiring the fixed record size not exceed 16k.
      This is still a fair amount of events (silly amount really) and leaves
      plenty room for callchains and stack dwarves while also avoiding

      perf/x86/intel/pebs: Add PEBS frontend profiling for Skylake

      Skylake has a new FRONTEND_LATENCY PEBS event to accurately profile
      frontend problems (like ITLB or decoding issues).

      The new event is configured through a separate MSR, which selects
      a range of sub events.

      Define the extra MSR as a extra reg and export support for it
      through sysfs.  To avoid duplicating the existing
      tables use a new function to add new entries to existing tables.

      perf/x86/intel: Make the CYCLE_ACTIVITY.* constraint on Broadwell more 
specific

      The counter constraint for CYCLE_ACTIVITY.* on Broadwell covered
      all CYCLE_ACTIVITY.* sub events, and forced them on counter 2.
      But actually only one sub event (umask 8) needs to be on counter 2,
      all others do not have any constraint.

      Only force that subevent. This fixes groups with multiple
      CYCLE_ACTIVITY.* events, for example:

        % perf stat -x, -e '{cpu/event=0xa3,umask=0x6,cmask=6/,\
        cpu/event=0xa2,umask=0x8/,\
        cpu/event=0xa3,umask=0x4,cmask=4/,cpu/event=0xb1,umask=0x1,cmask=1/}' 
true
        122150,,cpu/event=0xa3,umask=0x6,cmask=6/,846486,100.00
        16483,,cpu/event=0xa2,umask=0x8/,846486,100.00

      sched: Fix crash trying to dequeue/enqueue the idle thread

      Sasha reports that his virtual machine tries to schedule the idle
      thread since commit 6c37067e2786 ("sched: Change the
      sched_class::set_cpus_allowed() calling context").

      Hit trace shows this happening from idle_thread_get()->init_idle(),
      which is the _second_ init_idle() invocation on that task_struct, the
      first being done through idle_init()->fork_idle(). (this code is
      insane...)

      Because we call init_idle() twice in a row, its ->sched_class ==
      &idle_sched_class and ->on_rq = TASK_ON_RQ_QUEUED. This means
      do_set_cpus_allowed() think we're queued and will call dequeue_task(),
      which is implemented with BUG() for the idle class, seeing how
      dequeueing the idle task is a daft thing.

      Aside of the whole insanity of calling init_idle() _twice_, change the
      code to call set_cpus_allowed_common() instead as this is 'obviously'
      before the idle task gets ran etc..

      tcp_cubic: do not set epoch_start in the future

      Tracking idle time in bictcp_cwnd_event() is imprecise, as epoch_start
      is normally set at ACK processing time, not at send time.

      Doing a proper fix would need to add an additional state variable,
      and does not seem worth the trouble, given CUBIC bug has been there
      forever before Jana noticed it.

      Let's simply not set epoch_start in the future, otherwise
      bictcp_update() could overflow and CUBIC would again
      grow cwnd too fast.

      This was detected thanks to a packetdrill test Neal wrote that was flaky
      before applying this fix.

      vxlan: set needed headroom correctly

      vxlan_newlink (or vxlan_dev_configure) is called. This means
      vxlan->default_dst is actually unset in vxlan_setup and the condition that

      ARCNET: fix hard_header_len limit

      For arcnet the bare minimum header only contains the 4 bytes to
      specify source, dest and offset (1, 1 and 2 bytes respectively).
      The corresponding struct is struct arc_hardware.

      The struct archdr contains additionally a union of possible soft
      headers. When doing $insertusecasehere packets might well
      include short (or even no?) soft headers.

      For this reason only use arc_hardware instead of archdr to
      determine the hard_header_len for an arcnet device.

      net: bcmgenet: Implement RX coalescing control knobs

      Add support for the ethtool rx-frames coalescing parameter which allows
      defining the number of RX interrupts per frames received. The RDMA
      engine supports a configurable timeout with a resolution of
      approximately 8.192 us.

      We can no longer enable the BDONE/PDONE interrupts as those would
      fire for each packet/buffer received, which would defeat the MBDONE
      interrupt purpose. The MBDONE interrupt is guaranteed to correspond to a
      PDONE/BDONE interrupt when the threshold is set to 1.

      net: bcmgenet: Implement TX coalescing control knobs

      Configuring the ethtool tx-frames property, which translates into N
      packets before a TX interrupt is the simplest configuration scheme
      because it requires no locking neither at the softare nor hardware
      level, and is completely indepedent from the link speed. Since ethtool
      does not allow per-tx queue coalescing parameters, we apply the same
      setting to any transmit queue.

      We can no longer enable the BDONE/PDONE interrupts as those would fire
      for each packet/buffer received, which would defeat the MBDONE interrupt
      purpose. The MBDONE interrupt is guaranteed to correspond to a
      PDONE/BDONE interrupt when the threshold is set to 1, but offers
      interrupt coalescing when the value is > 1.

      Since the HW is configured to generate an interrupt when the ring
      becomes emtpy, we have to deny any timeout/timer settings coming from
      user-space to indicate we can only generate an interrupt very <N>
      packets.

      While we are at it, fix the DMA_INTR_THRESHOLD_MASK value which was off
      by one bit (0xff vs. 0x1ff).

      ipv6: ip6_fragment: fix headroom tests and skb leak

      David Woodhouse reports skb_under_panic when we try to push ethernet
      header to fragmented ipv6 skbs:

       skbuff: skb_under_panic: text:c1277f1e len:1294 put:14 head:dec98000
       data:dec97ffc tail:0xdec9850a end:0xdec98f40 dev:br-lan
      [..]
      ip6_finish_output2+0x196/0x4da

      David further debugged this:
        [..] offending fragments were arriving here with skb_headroom(skb)==10.
        Which is reasonable, being the Solos ADSL card's header of 8 bytes
        followed by 2 bytes of PPP frame type.

      The problem is that if netfilter ipv6 defragmentation is used, skb_cow()
      in ip6_forward will only see reassembled skb.

      Therefore, headroom is overestimated by 8 bytes (we pulled fragment
      header) and we don't check the skbs in the frag_list either.

      We can't do these checks in netfilter defrag since outdev isn't known yet.

      Furthermore, existing tests in ip6_fragment did not consider the fragment
      or ipv6 header size when checking headroom of the fraglist skbs.

      While at it, also fix a skb leak on memory allocation -- ip6_fragment
      must consume the skb.

      I tested this e1000 driver hacked to not allocate additional headroom
      (we end up in slowpath, since LL_RESERVED_SPACE is 16).

      If 2 bytes of headroom are allocated, fastpath is taken (14 byte
      ethernet header was pulled, so 16 byte headroom available in all
      fragments).

      The root cause is use of res.table uninitialized.

      Thanks to Nikolay for noticing the uninitialized use amongst the maze of
      gotos.

      As Nikolay pointed out the second initialization is not required to fix
      the oops, but rather to fix a related problem where a valid lookup should
      be invalidated before creating the rth entry.

      solos-pci: Increase headroom on received packets

      A comment in include/linux/skbuff.h says that:

       * Various parts of the networking layer expect at least 32 bytes of
       * headroom, you should not reduce this.

      This was demonstrated by a panic when handling fragmented IPv6 packets:
      http://marc.info/?l=linux-netdev&m=144236093519172&w=2

      It's not entirely clear if that comment is still valid â?? and if it is,
      perhaps netif_rx() ought to be enforcing it with a warning.

      But either way, it is rather stupid from a performance point of view
      for us to be receiving packets into a buffer which doesn't have enough
      room to prepend an Ethernet header â?? it means that *every* incoming
      packet is going to be need to be reallocated. So let's fix that.

  Date:   Thu Sep 17 16:01:51 2015 -0700

      lib/string_helpers.c: fix infinite loop in string_get_size()

      Some string_get_size() calls (e.g.:
       string_get_size(1, 512, STRING_UNITS_10, ..., ...)
       string_get_size(15, 64, STRING_UNITS_10, ..., ...)
      ) result in an infinite loop. The problem is that if size is equal to
      divisor[units]/blk_size and is smaller than divisor[units] we'll end
      up with size == 0 when we start doing sf_cap calculations:

      For string_get_size(1, 512, STRING_UNITS_10, ..., ...) case:
         ...
         remainder = do_div(size, divisor[units]); -> size is 0, remainder is 1
         remainder *= blk_size; -> remainder is 512
         ...
         size *= blk_size; -> size is still 0
         size += remainder / divisor[units]; -> size is still 0

      The caller causing the issue is sd_read_capacity(), the problem was
      noticed on Hyper-V, such weird size was reported by host when scanning
      collides with device removal.  This is probably a separate issue worth
      fixing, this patch is intended to prevent the library routine from
      infinite looping.

      kasan: fix last shadow judgement in memory_is_poisoned_16()

      The shadow which correspond 16 bytes memory may span 2 or 3 bytes.  If
      the memory is aligned on 8, then the shadow takes only 2 bytes.  So we
      check "shadow_first_bytes" is enough, and need not to call
      "memory_is_poisoned_1(addr + 15);".  But the code "if
      (likely(!last_byte))" is wrong judgement.

      e.g.  addr=0, so last_byte = 15 & KASAN_SHADOW_MASK = 7, then the code
      will continue to call "memory_is_poisoned_1(addr + 15);"

      zram: fix possible use after free in zcomp_create()

      zcomp_create() verifies the success of zcomp_strm_{multi,single}_create()
      through comp->stream, which can potentially be pointing to memory that
      was freed if these functions returned an error.

      While at it, replace a 'ERR_PTR(-ENOMEM)' by a more generic
      'ERR_PTR(error)' as in the future zcomp_strm_{multi,siggle}_create()
      could return other error codes.  Function documentation updated
      accordingly.

      bpf: add bpf_redirect() helper

      Existing bpf_clone_redirect() helper clones skb before redirecting
      it to RX or TX of destination netdev.
      Introduce bpf_redirect() helper that does that without cloning.

      Benchmarked with two hosts using 10G ixgbe NICs.
      One host is doing line rate pktgen.
      Another host is configured as:
      $ tc qdisc add dev $dev ingress
      $ tc filter add dev $dev root pref 10 u32 match u32 0 0 flowid 1:2 \
         action bpf run object-file tcbpf1_kern.o section clone_redirect_xmit 
drop
      so it receives the packet on $dev and immediately xmits it on $dev + 1
      The section 'clone_redirect_xmit' in tcbpf1_kern.o file has the program
      that does bpf_clone_redirect() and performance is 2.0 Mpps

      $ tc filter add dev $dev root pref 10 u32 match u32 0 0 flowid 1:2 \
         action bpf run object-file tcbpf1_kern.o section redirect_xmit drop
      which is using bpf_redirect() - 2.4 Mpps

      and using cls_bpf with integrated actions as:
      $ tc filter add dev $dev root pref 10 \
        bpf run object-file tcbpf1_kern.o section redirect_xmit integ_act 
classid 1
      performance is 2.5 Mpps

      To summarize:
      u32+act_bpf using clone_redirect - 2.0 Mpps
      u32+act_bpf using redirect - 2.4 Mpps
      cls_bpf using redirect - 2.5 Mpps

      For comparison linux bridge in this setup is doing 2.1 Mpps
      and ixgbe rx + drop in ip_rcv - 7.8 Mpps

      cls_bpf: introduce integrated actions

      Often cls_bpf classifier is used with single action drop attached.
      Optimize this use case and let cls_bpf return both classid and action.
      For backwards compatibility reasons enable this feature under
      TCA_BPF_FLAG_ACT_DIRECT flag.

      Then more interesting programs like the following are easier to write:
      int cls_bpf_prog(struct __sk_buff *skb)
      {
        /* classify arp, ip, ipv6 into different traffic classes
         * and drop all other packets
         */
        switch (skb->protocol) {
        case htons(ETH_P_ARP):
          skb->tc_classid = 1;
          break;
        case htons(ETH_P_IP):
          skb->tc_classid = 2;
          break;
        case htons(ETH_P_IPV6):
          skb->tc_classid = 3;
          break;
        default:
          return TC_ACT_SHOT;
        }

      tcp: provide skb->hash to synack packets

      In commit b73c3d0e4f0e ("net: Save TX flow hash in sock and set in skbuf
      on xmit"), Tom provided a l4 hash to most outgoing TCP packets.

      We'd like to provide one as well for SYNACK packets, so that all packets
      of a given flow share same txhash, to later enable bonding driver to
      also use skb->hash to perform slave selection.

      Note that a SYNACK retransmit shuffles the tx hash, as Tom did
      in commit 265f94ff54d62 ("net: Recompute sk_txhash on negative routing
      advice") for established sockets.

      This has nice effect making TCP flows resilient to some kind of black
      holes, even at connection establish phase.

      ====================
      Passing net through the netfilter hooks

      My primary goal with this patchset and it's follow ups is to cleanup the
      network routing paths so that we do not look at the output device to
      derive the network namespace.  My plan is to pass the network namespace
      of the transmitting socket through the output path, to replace code that
      looks at the output network device today.  Once that is done we can have
      routes with output devices outside of the current network namespace.
      Which should allow reception and transmission of packets in network
      namespaces to be as fast as normal packet reception and transmission
      with early demux disabled, because it will same code path.

      Once skb_dst(skb)->dev is a little better under control I think it will
      also be possible to use rcu to cleanup the ancient hack that sets
      dst->dev to loopback_dev when a network device is removed.

      The work to get there is a series of code cleanups.  I am starting with
      passing net into the netfilter hooks and into the functions that are
      called after the netfilter hooks.  This removes from netfilter the
      need to guess which network namespace it is working on.

      To get there I perform a series of minor prep patches so the big changes
      at the end are possible to audit without getting lost in the noise.  In
      particular I have a lot of patches computing net into a local variable
      and then using it through out the function.

      So this patchset encompases removing dead code, sorting out the _sk
      functions that were added last time someone pushed a prototype change
      through the post netfilter functions.  Cleaning up individual functions
      use of the network namespace.  Passing net into the netfilter hooks.
      Passing net into the post netfilter functions.  Using state->net in
      the netfilter code where it is available and trivially usable.

      Pablo, Dave I don't know whose tree this makes more sense to go
      through.  I am assuming at least initially Pablos as netfilter is
      involved.  From what I have seen there will be a lot of back and forth
      between the netfilter code paths and the routing code paths.

      The patches are also available (against 4.3-rc1) at:
      git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/net-next.git master

      netfilter: Add blank lines in callers of netfilter hooks

      In code review it was noticed that I had failed to add some blank lines
      in places where they are customarily used.  Taking a second look at the
      code I have to agree blank lines would be nice so I have added them
      here.

      netfilter: Pass net into okfn

      This is immediately motivated by the bridge code that chains functions 
that
      call into netfilter.  Without passing net into the okfns the bridge code 
would
      need to guess about the best expression for the network namespace to 
process
      packets in.

      As net is frequently one of the first things computed in continuation 
functions
      after netfilter has done it's job passing in the desired network 
namespace is in
      many cases a code simplification.

      To support this change the function dst_output_okfn is introduced to
      simplify passing dst_output as an okfn.  For the moment dst_output_okfn
      just silently drops the struct net.

      netfilter: Pass struct net into the netfilter hooks

      Pass a network namespace parameter into the netfilter hooks.  At the
      call site of the netfilter hooks the path a packet is taking through
      the network stack is well known which allows the network namespace to
      be easily and reliabily.

      This allows the replacement of magic code like
      "dev_net(state->in?:state->out)" that appears at the start of most
      netfilter hooks with "state->net".

      In almost all cases the network namespace passed in is derived
      from the first network device passed in, guaranteeing those
      paths will not see any changes in practice.

      The exceptions are:
      xfrm/xfrm_output.c:xfrm_output_resume()         xs_net(skb_dst(skb)->xfrm)
      ipvs/ip_vs_xmit.c:ip_vs_nat_send_or_cont()      ip_vs_conn_net(cp)
      ipvs/ip_vs_xmit.c:ip_vs_send_or_cont()          ip_vs_conn_net(cp)
      ipv4/raw.c:raw_send_hdrinc()                    sock_net(sk)
      ipv6/ip6_output.c:ip6_xmit()                      sock_net(sk)
      ipv6/ndisc.c:ndisc_send_skb()                   dev_net(skb->dev) not 
dev_net(dst->dev)
      ipv6/raw.c:raw6_send_hdrinc()                   sock_net(sk)
      br_netfilter_hooks.c:br_nf_pre_routing_finish() dev_net(skb->dev) before 
skb->dev is set to nf_bridge->physindev

      In all cases these exceptions seem to be a better expression for the
      network namespace the packet is being processed in then the historic
      "dev_net(in?in:out)".  I am documenting them in case something odd
      pops up and someone starts trying to track down what happened.

      net: Remove dev_queue_xmit_sk

      A function with weird arguments that it will never use to accomdate a
      netfilter callback prototype is absolutely in the core of the
      networking stack.  Frankly it does not make sense and it causes a lot
      of confusion as to why arguments that are never used are being passed
      to the function.

      As I am preparing to make a second change to arguments to the okfn even
      the names stops making sense.

      As I have removed the two callers of this function remove this confusion
      from the networking stack.

      Intel Wired LAN Driver Updates 2015-09-15

      This series contains updates to ixgbe and fm10k.

      Don fixes a ixgbe issue by adding checks for systems that do not have
      SFP's to avoid incorrectly acting on interrupts that are falsely
      interpreted as SFP events.

      Alex Williamson adds a fix for ixgbe to disable SR-IOV prior to
      unregistering the netdev to avoid issues with guest OS's which do not
      support hot-unplug or their hot-unplug is broken.

      Alex Duyck update the lowest limit for adaptive interrupt interrupt
      moderation to about 12K interrupts per second for ixgbe.  This change
      increases the performance for ixgbe.  Also fixed up fm10k to remove
      the optimization that assumed that all fragments would be limited to
      page size, since that assumption is incorrect as the TCP allocator can
      provide up to a 32K page fragment.  Updated fm10k to add the MAC
      address to the list of values recorded on driver load.  Fixes fm10k
      so that we only trigger the data path reset if the fabric is ready to
      handle traffic to avoid triggering the reset unless the switch API is
      ready for us.

      Jacob updates the fm10k driver to disable the service task during
      suspend and re-enable it after we resume. If we don't do this, the
      device could be UP when you suspend and come back from resume as
      DOWN.  Also update fm10k to prevent the removal of default VID rules,
       and correctly remove the stack layers information of the VLAN, but then
      return to forwarding that VID as untagged frames.  If we deleted the VID
      rules here, we would begin dropping traffic due to VLAN membership
      violations.  Fixed fm10k to use pcie_get_minimum_link(), which is useful
      in cases where we connect to a slot at Gen3, but the slot is behind a bus
      which is only connected at Gen2.  Updated fm10k to update the netdev
      permanent address during reinit instead of up to enable users to
      immediately see the new MAC address on the VF even if the device is not
      up.  Adds the creation of VLAN interfaces on a device, even while the
      device is down for fm10k.  Fixed an issue where we request the incorrect
      MAC/VLAN combinations, and prevents us from accidentally reporting some
      frames as VLAN tagged.  Provided a couple of trivial fixes for fm10k
      to fix code style and typos in code comments.

      net: Fix vti use case with oif in dst lookups

      Steffen reported that the recent change to add oif to dst lookups breaks
      the VTI use case. The problem is that with the oif set in the flow struct
      the comparison to the nh_oif is triggered. Fix by splitting the
      FLOWI_FLAG_VRFSRC into 2 flags -- one that triggers the vrf device cache
      bypass (FLOWI_FLAG_VRFSRC) and another telling the lookup to not compare
      nh oif (FLOWI_FLAG_SKIP_NH_OIF).

      net-sysfs: get_netdev_queue_index() cleanup

      Redo commit ed1acc8cd8c22efa919da8d300bab646e01c2dce.

      Commit 822b3b2ebfff8e9b3d006086c527738a7ca00cd0 ("net: Add max rate tx 
queue
      attribute") moved get_netdev_queue_index around, but kept the old version.
      Probably because of a reuse of the original patch from before Eric's 
change to
      that function.

      Remove one inline keyword, and no need for a loop to find
      an index into a table.

      SUNRPC: Ensure that we wait for connections to complete before retrying

      Commit 718ba5b87343, moved the responsibility for unlocking the socket to
      xs_tcp_setup_socket, meaning that the socket will be unlocked before we
      know that it has finished trying to connect. The following patch is based 
on

      slave driver. This makes this driver a bit more PXA agnostic.

      The driver was tested on pxa27x (mainstone) and pxa310 (zylonite),

      Failing to send a CLOSE if file is opened WRONLY and server reboots on a 
4.x mount

      A test case is as the description says:
      open(foobar, O_WRONLY);
      sleep()  --> reboot the server
      close(foobar)

      The bug is because in nfs4state.c in nfs4_reclaim_open_state() a few
      line before going to restart, there is
      clear_bit(NFS4CLNT_RECLAIM_NOGRACE, &state->flags).

      NFS4CLNT_RECLAIM_NOGRACE is a flag for the client states not open
      owner states. Value of NFS4CLNT_RECLAIM_NOGRACE is 4 which is the
      value of NFS_O_WRONLY_STATE in nfs4_state->flags. So clearing it wipes
      out state and when we go to close it, â??call_closeâ?? doesnâ??t get set 
as
      state flag is not set and CLOSE doesnâ??t go on the wire.

      of_pci_irq: Silence bogus "of_irq_parse_pci() failed ..." messages.

      It is perfectly legitimate for a PCI device to have an
      PCI_INTERRUPT_PIN value of zero.  This happens if the device doesn't
      use interrupts, or on PCIe devices, where only MSI/MSI-X are
      supported.

      Silence the annoying "of_irq_parse_pci() failed with rc=-19" error
      messages by moving the printing code into of_irq_parse_pci(), and only
      emitting the message for cases where PCI_INTERRUPT_PIN == 0 is not the
      cause for an early exit.

      The bma180 / bma250 accelerometers share a driver (at least under Linux),
      so it makes sense to also have their bindings info in a single .txt.

      This commit extends the bma180 bindings with bma250 bindings, specifically
      it specifies how the 2 seperate interrupts the bma250 has must be listed
      in devicetree. The existing bma180 driver is already fully compatible

      perf tools: Bool functions shouldn't return -1

      Returning a negative value for a boolean function seem to have the
      undesired effect of returning true. Replace -1 by false in a
      bool-returning function.

        3907c3907

        >       xorl    %ebx, %ebx

      while if -1 is replaced by true, the diff is empty.

      regulator: core: Correct return value check in regulator_resolve_supply

      The ret pointer passed to regulator_dev_lookup is only filled with a
      valid error code if regulator_dev_lookup returned NULL. Currently
      regulator_resolve_supply checks this ret value before it checks if a
      regulator was returned, this can result in valid regulator lookups being
      ignored.

      This reverts commit f785f2357673d520a0b7b468973cdd197f336494.

      We have a test to check if elf_getphdrnum() is present, so, if it fails,
      we'll get:

        [acme@rhel5 linux]$ cat 
/tmp/build/perf/feature/test-libelf-getphdrnum.make.output
        cc1: warnings being treated as errors
        test-libelf-getphdrnum.c: In function â??mainâ??:
        test-libelf-getphdrnum.c:7: warning: implicit declaration of function 
â??elf_getphdrnumâ??
        [acme@rhel5 linux]$

      And this block will not be compiled:

        #ifndef HAVE_ELF_GETPHDRNUM_SUPPORT
        static int elf_getphdrnum(Elf *elf, size_t *dst)
        ...
        #endif

      So, if elf_getphdrnum() is being defined somewhere, there is a problem
      with the test that is not detecting that function, go fix it.

      block: fix bounce_end_io

      When bio bounce is involved, one new bio and its biovecs are
      cloned from the comming bio, which can be one fast-cloned bio
      from upper layer(such as dm).

      So it is obviously wrong to assume the start index of the coming(
      original) bio's io vector is zero, which can be any value between
      0 and (bi_max_vecs - 1), especially in case of bio split.

      This patch fixes Fedora's booting oops on i386, often with the
      following kernel log together:

      block: blk-merge: fast-clone bio when splitting rw bios

      biovecs has become immutable since v3.13, so it isn't necessary
      to allocate biovecs for the new cloned bios, then we can save
      one extra biovecs allocation/copy, and the allocation is often
      not fixed-length and a bit more expensive.

      For example, if the 'max_sectors_kb' of null blk's queue is set
      as 16(32 sectors) via sysfs just for making more splits, this patch
      can increase throught about ~70% in the sequential read test over
      null_blk(direct io, bs: 1M).

      libiscsi: Fix iscsi_check_transport_timeouts possible infinite loop

      Connection last_ping is not being updated when iscsi_send_nopout fails.
      Not updating the last_ping will cause firing a timer to a past time
      (last_ping + ping_tmo < current_time) which triggers an infinite loop of
      iscsi_check_transport_timeouts() and hogs the cpu.

      Fix this issue by checking the return value of iscsi_send_nopout.
      If it fails set the next_timeout to one second later.

      x86/pci/dma: Fix gfp flags for coherent DMA memory allocation

      Commit 6894258eda2f reversed the order of gfp_flags adjustment in
      dma_alloc_attrs() for x86 [arch/x86/kernel/pci-dma.c] As a result,
      relevant flags set by dma_alloc_coherent_gfp_flags() are just
      discarded and cause coherent DMA memory allocation failure on some
      devices.

      arm/arm64: KVM: Remove 'config KVM_ARM_MAX_VCPUS'

      This patch removes config option of KVM_ARM_MAX_VCPUS,
      and like other ARCHs, just choose the maximum allowed
      value from hardware, and follows the reasons:

      1) from distribution view, the option has to be
      defined as the max allowed value because it need to
      meet all kinds of virtulization applications and
      need to support most of SoCs;

      2) using a bigger value doesn't introduce extra memory
      consumption, and the help text in Kconfig isn't accurate
      because kvm_vpu structure isn't allocated until request
      of creating VCPU is sent from QEMU;

      3) the main effect is that the field of vcpus[] in 'struct kvm'
      becomes a bit bigger(sizeof(void *) per vcpu) and need more cache
      lines to hold the structure, but 'struct kvm' is one generic struct,
      and it has worked well on other ARCHs already in this way. Also,
      the world switch frequecy is often low, for example, it is ~2000
      when running kernel building load in VM from APM xgene KVM host,
      so the effect is very small, and the difference can't be observed
      in my test at all.

      Whilst this breaks migrating a guest started on a previous version of

      s390/vtime: correct scaled cputime for SMT

      The scaled cputime is supposed to be derived from the normal per-thread
      cputime by dividing it with the average thread density in the last 
interval.

      The calculation of the scaling values for the average thread density is
      incorrect. The current, incorrect calculation:

          Ci = cycle count with i active threads
          T = unscaled cputime, sT = scaled cputime
          sT = T * (C1 + C2 + ... + Cn) / (1*C1 + 2*C2 + ... + n*Cn)

      The calculation happens to yield the correct numbers for the simple cases
      with only one Ci value not zero. But for cases with multiple Ci values not
      zero it fails. E.g. on a SMT-2 system with one thread active half the time
      and two threads active for the other half of the time it fails, the 
scaling
      factor should be 3/4 but the formula gives 2/3.

      The correct formula is

          sT = T * (C1/1 + C2/2 + ... + Cn/n) / (C1 + C2 + ... + Cn)

      Use ENOENT to indicate that particular counters are not available when the

events,
      this might trigger a fall back, for example, to a software event.

      s390/compat: correct uc_sigmask of the compat signal frame

      The uc_sigmask in the ucontext structure is an array of words to keep
      the 64 signal bits (or 1024 if you ask glibc but the kernel sigset_t
      only has 64 bits).

      For 64 bit the sigset_t contains a single 8 byte word, but for 31 bit
      there are two 4 byte words. The compat signal handler code uses a
      simple copy of the 64 bit sigset_t to the 31 bit compat_sigset_t.
      As s390 is a big-endian architecture this is incorrect, the two words
      in the 31 bit sigset_t array need to be swapped.

      attached to that fragment, creating an invalid SCO packets.

      Controllers like Intel's WilkinsPeak are always fragmenting
      SCO packet into 3 parts (#1, #2, #3). Packet #1 contains
      SCO header and audio data, others just audio data. if there is
      a fragment cached from previous connection, i.e. #1, first
      SCO packet from new connection is going to be attached to it
      creating packet consisting of fragments #1-#1-#2. This will
      be forwarded to upper layers. After that, fragment #3 is going
      to be used as a starting point for another SCO packet.
      It does not contain a SCO header, but the code expects it,
      casts a SCO header structure on it, and reads whatever audio
      data happens to be there as SCO packet length and handle.
      From that point on, we are assembling random data into SCO
      packets. Usually it recovers quickly as initial audio data
      contains mostly zeros (muted stream), but setups of over
      4 seconds were observed.
      Issue manifests itself by printing on the console:
      Bluetooth: hci0 SCO packet for unknown connection handle 48
      Bluetooth: hci0 SCO packet for unknown connection handle 2560
      Bluetooth: hci0 SCO packet for unknown connection handle 12288
      It may also show random handles if audio data was non-zeroed.
      Hcidump shows SCO packets with random length and handles.

      Few messages with handle 0 at connection creation are OK
      for some controllers (like WilkinsPeak), as there are SCO packets
      with zeroed handle at the beginning (possible controller bug).
      Few of such messages at connection end, with a handle looking
      sane (around 256, 512, 768 ...) is also OK, as these are last
      SCO packets that were assembled and sent up, before connection
      was ended, but were not handled in time.

      This issue may still manifest itself on WilkinsPeak as it sometimes,
      at SCO connection creation, does not send third fragment of first
      SCO packet (#1-#2-#1-#2-#3...). This is a firmware bug and this
      patch does not address it.

      at86rf230: change trac status check behaviour

      When transmit is done, indicated by trx_end irq, we do first a force
      state change to TX_ON and then checking the trac status, if the trac
      status is unequal zero we do a state change to TRX_OFF.

      This patch changes to the following behaviour, we first check on trac
      status after trx_end occurs and then doing a normal change to TX_ON
      without do the state change to TRX_OFF when trac status is unequal zero.

      The reasons are that the datasheet doesn't described when the trac
      status register is cleared, we should doing to evaluate the trac status
      at first. The reason to remove the TRX_OFF change if the trac status is
      unequal to zero and it was force is the following paragraph inside The
      at86rf2xx datasheets:

      "Using FORCE_PLL_ON to interrupt an TX_ARET transaction, it is
       recommended to check register bits [7:5] of register address 0x32 for
       value 0. If this value is different, TRX_CMD sequence FORCE_TRX_OFF shall
       be used immediately followed by TRX_CMD sequence PLL_ON. This performs a
       state transition to PLL_ON."

      The meaning is here "to interrupt an TX_ARET transaction" in case of
      trx_end interrupt the "TX_ARET transaction" is already done and we don't
      interrupt the "TX_ARET transaction" by doing the change to TX_ON (PLL_ON)
      here. Additional I changed the force change to normal TX_ON which seems to
      work here.

      ieee802154: 6lowpan: use correct ESC value for dispatch

      The ESC dispatch value has some history and it originally was 0x7f in 
rfc4944
      (see section-5.1). With the release of rfc6282 this value got part of the
      LOWPAN_IPHC range and was no longer available for ESC. Instead 0x40 was 
used
      as replacement (see section-2 in rfc6282).

      We have been checking the dispatch byte in an order where IPHC would 
always be
      evaluated before ESC and thus we would never reach the ESC check as the 
IPHC
      range already covers this value.

      ieee802154: 6lowpan: change if lowpan dev is running

      We don't need to check if the wpan interface is running because the
      lowpan_rcv is the packet layer receive handler for the wpan interface.

      Instead doing a check if wpan interface is running we should check if
      the lowpan interface is running before starting 6lowpan adaptation layer.

      ieee802154: 6lowpan: register packet layer while open

      This patch moves the open count handling while doing open of a lowpan
      interface. We need the packet handler register at first when one lowpan
      interface is up. There exists a small case when all lowpan interfaces
      are down and the 802154 packet layer is still registered. To reduce some
      overhead we will register the packet layer when the first lowpan
      interface comes up and unregister when the last interface will become 
down.

      Inside the IEEE 802.15.4 6LoWPAN subsystem we use two interfaces which
      are wpan and lowpan interfaces. Instead of using always the variable
      name "dev" for both we rename the "dev" variable to wdev which means the
      wpan net_device and ldev which means a lowpan net_device. This avoids
      confusing and always looking back to see which net_device is meant by
      the variable name "dev".

      Bluetooth: btmrvl: skb resource leak, and double free.

      if btmrvl_tx_pkt() is called, and the branch
        if (skb_headroom(skb) < BTM_HEADER_LEN)
      evaluates positive, a new skb is allocated via skb_realloc_headroom.

      The original skb is stored in a tmp variable, before being free'd.
      However on success, the new skb, is not free'd, nor is it
      returned to the caller which will then double-free the original skb.

      This issue exists from the original driver submission in
       commit: #132ff4e5fa8dfb71a7d99902f88043113947e972

      If this code path had been alive, it would have been noted from the
      double-free causing a panic.

      All skb's here should be allocated through bt_skb_alloc which
      adds 8 bytes as headroom, which is plenty against the 4 bytes
      pushed on by this driver.

      This code path is dead, and buggy at the same time, so the cleanest
      approach is to remove the affected branch.

      Bluetooth: close HCI device when user channel socket gets closed

      With 9380f9eacfbbee701daa416edd6625efcd3e29e1 the order of unsetting
      the HCI_USER_CHANNEL flag of the HCI device was reverted to ensure
      the device is first closed before making it available again.

      Due to hci_dev_close checking for HCI_USER_CHANNEL being set on the
      device it was never really closed and was kept opened. We're now
      calling hci_dev_do_close directly to make sure the device is correctly
      closed and we keep the correct order to unset the flag on our device
      object.

      arm64: errata: add module build workaround for erratum #843419

      Cortex-A53 processors <= r0p4 are affected by erratum #843419 which can
      lead to a memory access using an incorrect address in certain sequences
      headed by an ADRP instruction.

      There is a linker fix to generate veneers for ADRP instructions, but
      this doesn't work for kernel modules which are built as unlinked ELF
      objects.

      This patch adds a new config option for the erratum which, when enabled,
      builds kernel modules with the mcmodel=large flag. This uses absolute
      addressing for all kernel symbols, thereby removing the use of ADRP as
      a PC-relative form of addressing. The ADRP relocs are removed from the
      module loader so that we fail to load any potentially affected modules.

      arm64: compat: fix vfp save/restore across signal handlers in big-endian

      When saving/restoring the VFP registers from a compat (AArch32)
      signal frame, we rely on the compat registers forming a prefix of the
      native register file and therefore make use of copy_{to,from}_user to
      transfer between the native fpsimd_state and the compat_vfp_sigframe.

      Unfortunately, this doesn't work so well in a big-endian environment.
      Our fpsimd save/restore code operates directly on 128-bit quantities
      (Q registers) whereas the compat_vfp_sigframe represents the registers
      as an array of 64-bit (D) registers. The architecture packs the compat D
      registers into the Q registers, with the least significant bytes holding
      the lower register. Consequently, we need to swap the 64-bit halves when
      converting between these two representations on a big-endian machine.

      This patch replaces the __copy_{to,from}_user invocations in our
      compat VFP signal handling code with explicit __put_user loops that
      operate on 64-bit values and swap them accordingly.

      arm64: cpu hotplug: ensure we mask out CPU_TASKS_FROZEN in notifiers

      We have a couple of CPU hotplug notifiers for resetting the CPU debug
      state to a sane value when a CPU comes online.

      This patch ensures that we mask out CPU_TASKS_FROZEN so that we don't
      miss any online events occuring due to suspend/resume.

      ath10k: implement mesh support

      Add support for mesh to ath10k.  We simply use an AP virtual interface
      in the firmware in order to enable beaconing without TSF adoption, and
      use the raw (802.11) transmit mode.

      Due to firmware limitations, the firmware must operate in raw
      (non-native 802.11) mode.  As this is configured at firmware init time,
      a new "rawmode" modparam is added, and mesh interfaces are available
      only if rawmode=true.  The firmware must advertise support for rawmode;
      tested successfully with firmware 10.2.4.70.6-2.

      When the module is loaded with (newly implemented) modparam rawmode=1, it
      will enable operating an open mesh STA via something like the following:

          ip link set wlan0 down
          iw dev wlan0 set type mp
          ip link set wlan0 up
          iw dev wlan0 set freq 5745 80 5775
          iw dev wlan0 mesh join mesh-vht

      Bluetooth: Delay check for conn->smp in smp_conn_security()

      There are several actions that smp_conn_security() might make that do
      not require a valid SMP context (conn->smp pointer). One of these
      actions is to encrypt the link with an existing LTK. If the SMP
      context wasn't initialized properly we should still allow the
      independent actions to be done, i.e. the check for the context should
      only be done at the last possible moment.

      leds:lp55xx: Correct Kconfig dependency for f/w user helper

      The commit [b67893206fc0: leds:lp55xx: fix firmware loading error]
      tries to address the firmware file handling with user helper, but it
      sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK.  Since the
      wrong option was enabled, the system got a regression -- it suffers
      from the unexpected long delays for non-present firmware files.

      This patch corrects the Kconfig dependency to the right one,
      CONFIG_FW_LOADER_USER_HELPER.  This doesn't change the fallback
      behavior but only enables UMH when needed.

      ARM: dts: am57xx-beagle-x15: Update Phy supplies

      Originally, all the SoC PHY rails were supplied by LDO3. However, as a
      result of characterization, it was determined that this posed a risk in
      extreme load  conditions. Hence the PHY rails are split between two
      different LDOs. Update the related node as a result

      LDO3/VDDA_1V8_PHYA supplies vdda_usb1, vdda_usb2, vdda_sata, vdda_usb3
      LDO4/VDDA_1V8_PHYB supplies vdda_pcie1, vdda_pcie0, vdda_hdmi, vdda_pcie

      NOTE: We break compatibility with pre-production boards with this change
      since, the PMIC LDO4 is disabled at OTP level.

      The new configuration is the plan of record and all pre-production
      boards are supposed to be replaced with the latest boards matching the
      mentioned configuration.

      Some very few 10 something boards have been created and
      stopped production till the latest modifications were done (PMIC USB
      interrupt, LDO4 etc) - and all of those boards are now getting
      scrapped.. If there are any (as per tracking information, there should
      not be any), TI should be contacted to have them replaced.

      ARM: 8425/1: kgdb: Don't try to stop the machine when setting breakpoints

      In (23a4e40 arm: kgdb: Handle read-only text / modules) we moved to
      using patch_text() to set breakpoints so that we could handle the case
      when we had CONFIG_DEBUG_RODATA.  That patch used patch_text().
      Unfortunately, patch_text() assumes that we're not in atomic context
      when it runs since it needs to grab a mutex and also wait for other
      CPUs to stop (which it does with a completion).

      This would result in a stack crawl if you had
      CONFIG_DEBUG_ATOMIC_SLEEP and tried to set a breakpoint in kgdb.  The

      Commit 96231b2686b5: ("ARM: 8419/1: dma-mapping: harmonize definition

      Mark 800MHz OPP as a suspend opp for Exynos4412 based
      boards so effectively cpufreq-dt driver behavior w.r.t.
      suspend frequency matches what the old exynos-cpufreq
      driver has been doing.

      This patch fixes suspend/resume support on Exynos4412 based
      Trats2 board and reboot hang on Exynos4412 based Odroid U3

      ARM: dts: Fix LEDs on exynos5422-odroidxu3

      The LEDs on Odroid XU3 family boards could not properly probe
      because PWM outputs were reduced only to PWM for fan. Fix it
      for Odroid XU3 and XU3-Lite boards by switching to usage of
      all 4 outputs (although the PWM for MIPI probably is redundant
      because board does not have MIPI connector available).

      This fixes warnings on dmesg:

      clk: check for invalid parent index of orphans in __clk_init()

      If a mux clock is initialised (by hardware or firmware) with an
      invalid parent, its ->get_parent() can return an out of range
      index.  For example, the generic mux clock attempts to return
      -EINVAL, which due to the u8 return type ends up a rather large
      number.  Using this index with the parent_names[] array results
      in an invalid pointer and (usually) a crash in the following
      strcmp().

      This patch adds a check for the parent index being in range,
      ignoring clocks reporting invalid values.

      perf stat: Fix per-pkg event reporting bug

      Per-pkg events need to be captured once per processor socket. The code
      in check_per_pkg() ensures only one value per processor package is used.
      However there is a problem with this function in case the first CPU of
      the package does not measure anything for the per-pkg event, but other
      CPUs do.

      Consider the following:

        $ create cgroup FOO; echo $$ >FOO/tasks; taskset -c 1 noploop &
        $ perf stat -a -I 1000 -e intel_cqm/llc_occupancy/ -G FOO sleep 100
          1.00000 <not counted> Bytes intel_cqm/llc_occupancy/  FOO

      The reason for this is that CPU0 in the cgroup has nothing running on it.
      Yet check_per_plg() will mark socket0 as processed and no other event
      value will be considered for the socket.

      This patch fixes the problem by having check_per_pkg() only consider
      events which actually ran.

      ASoC: fix broken pxa SoC support

      The previous fix of pxa library support, which was introduced to fix the
      library dependency, broke the previous SoC behavior, where a machine
      code binding pxa2xx-ac97 with a coded relied on :
       - sound/soc/pxa/pxa2xx-ac97.c
       - sound/soc/codecs/XXX.c

      For example, the mioa701_wm9713.c machine code is currently broken. The
      "select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for
      compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared
      in sound/arm/Kconfig and sound/soc/pxa/Kconfig.

      Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct
      pxa2xx-ac97 compilation.

      arm/arm64: KVM: vgic: Check for !irqchip_in_kernel() when mapping

      Until b26e5fdac43c ("arm/arm64: KVM: introduce per-VM ops"),
      kvm_vgic_map_resources() used to include a check on irqchip_in_kernel(),
      and vgic_v2_map_resources() still has it.

      But now vm_ops are not initialized until we call kvm_vgic_create().
      Therefore kvm_vgic_map_resources() can being called without a VGIC,
      and we die because vm_ops.map_resources is NULL.

      Fixing this restores QEMU's kernel-irqchip=off option to a working state,
      allowing to use GIC emulation in userspace.

      Revert "sched, cgroup: replace signal_struct->group_rwsem with a global 
percpu_rwsem"

      This reverts commit d59cfc09c32a2ae31f1c3bc2983a0cd79afb3f14.

      d59cfc09c32a ("sched, cgroup: replace signal_struct->group_rwsem with
      a global percpu_rwsem") and b5ba75b5fc0e ("cgroup: simplify
      threadgroup locking") changed how cgroup synchronizes against task
      fork and exits so that it uses global percpu_rwsem instead of
      per-process rwsem; unfortunately, the write [un]lock paths of
      percpu_rwsem always involve synchronize_rcu_expedited() which turned
      out to be too expensive.

      Improvements for percpu_rwsem are scheduled to be merged in the coming
      v4.4-rc1 merge window which alleviates this issue.  For now, revert
      the two commits to restore per-process rwsem.  They will be re-applied
      for the v4.4-rc1 merge window.

      The offending commit accidentally replaces an atomic_clear with an
      atomic_or instead of an atomic_andnot in kvm_s390_vcpu_request_handled.
      The symptom is that kvm guests on s390 hang on startup.

      sh: Kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      x86/platform: Fix Geode LX timekeeping in the generic x86 build

      In 2007, commit 07190a08eef36 ("Mark TSC on GeodeLX reliable")
      bypassed verification of the TSC on Geode LX. However, this code
      (now in the check_system_tsc_reliable() function in
      arch/x86/kernel/tsc.c) was only present if CONFIG_MGEODE_LX was
      set.

      OpenWRT has recently started building its generic Geode target
      for Geode GX, not LX, to include support for additional
      platforms. This broke the timekeeping on LX-based devices,
      because the TSC wasn't marked as reliable:
      https://dev.openwrt.org/ticket/20531

      By adding a runtime check on is_geode_lx(), we can also include
      the fix if CONFIG_MGEODEGX1 or CONFIG_X86_GENERIC are set, thus
      fixing the problem.

      arm: KVM: Fix incorrect device to IPA mapping

      A critical bug has been found in device memory stage1 translation for
      VMs with more then 4GB of address space. Once vm_pgoff size is smaller
      then pa (which is true for LPAE case, u32 and u64 respectively) some
      more significant bits of pa may be lost as a shift operation is performed
      on u32 and later cast onto u64.

      Example: vm_pgoff(u32)=0x00210030, PAGE_SHIFT=12
              expected pa(u64):   0x0000002010030000
              produced pa(u64):   0x0000000010030000

      The fix is to change the order of operations (casting first onto

      arm64: KVM: Fix user access for debug registers

      When setting the debug register from userspace, make sure that
      copy_from_user() is called with its parameters in the expected
      order. It otherwise doesn't do what you think.

      genirq: Remove irq argument from irq flow handlers

      Most interrupt flow handlers do not use the irq argument. Those few
      which use it can retrieve the irq number from the irq descriptor.

      Remove the argument.

      Search and replace was done with coccinelle and some extra helper
      scripts around it. Thanks to Julia for her help!

      KVM: vmx: fix VPID is 0000H in non-root operation

      Reference SDM 28.1:

      The current VPID is 0000H in the following situations:
      - Outside VMX operation. (This includes operation in system-management
        mode under the default treatment of SMIs and SMM with VMX operation;
        see Section 34.14.)
      - In VMX root operation.
      - In VMX non-root operation when the â??enable VPIDâ?? VM-execution 
control
        is 0.

      The VPID should never be 0000H in non-root operation when "enable VPID"
      VM-execution control is 1. However, commit 34a1cd60 ("kvm: x86: vmx:
      move some vmx setting from vmx_init() to hardware_setup()") remove the
      codes which reserve 0000H for VMX root operation.

      This patch fix it by again reserving 0000H for VMX root operation.

      powerpc/mm: Recompute hash value after a failed update

      If we had secondary hash flag set, we ended up modifying hash value in
      the updatepp code path. Hence with a failed updatepp we will be using
      a wrong hash value for the following hash insert. Fix this by
      recomputing hash before insert.

      Without this patch we can end up with using wrong slot number in linux
      pte. That can result in us missing an hash pte update or invalidate
      which can cause memory corruption or even machine check.

      KVM: add halt_attempted_poll to VCPU stats

      This new statistic can help diagnosing VCPUs that, for any reason,
      trigger bad behavior of halt_poll_ns autotuning.

      For example, say halt_poll_ns = 480000, and wakeups are spaced exactly
      like 479us, 481us, 479us, 481us. Then KVM always fails polling and wastes
      10+20+40+80+160+320+480 = 1110 microseconds out of every
      479+481+479+481+479+481+479 = 3359 microseconds. The VCPU then
      is consuming about 30% more CPU than it would use without
      polling.  This would show as an abnormally high number of
      attempted polling compared to the successful polls.

      ARM: fix Thumb2 signal handling when ARMv6 is enabled

      When a kernel is built covering ARMv6 to ARMv7, we omit to clear the
      IT state when entering a signal handler.  This can cause the first
      few instructions to be conditionally executed depending on the parent
      context.

      In any case, the original test for >= ARMv7 is broken - ARMv6 can have
      Thumb-2 support as well, and an ARMv6T2 specific build would omit this
      code too.

      Relax the test back to ARMv6 or greater.  This results in us always
      clearing the IT state bits in the PSR, even on CPUs where these bits
      are reserved.  However, they're reserved for the IT state, so this
      should cause no harm.

      User visible changes:

      - Enhance the error reporting of tracepoint event parsing, e.g.:

          $ oldperf record -e sched:sched_switc usleep 1
          event syntax error: 'sched:sched_switc'
                               \___ unknown tracepoint
          Run 'perf list' for a list of valid events

        Now we get the much nicer:

          $ perf record -e sched:sched_switc ls
          event syntax error: 'sched:sched_switc'
                               \___ can't access trace events

          Error: No permissions to read 
/sys/kernel/debug/tracing/events/sched/sched_switc
          Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug'

        And after we have those mount point permissions fixed:

          $ perf record -e sched:sched_switc ls
          event syntax error: 'sched:sched_switc'
                               \___ unknown tracepoint

          Error: File /sys/kernel/debug/tracing/events/sched/sched_switc not 
found.
          Hint:  Perhaps this kernel misses some CONFIG_ setting to enable this 
feature?.

        Now its just a matter of using what git uses to suggest alternatives 
when we
        make a typo, i.e. that it is just an 'h' missing :-)

        I.e. basically now the event parsing routing uses the strerror_open()
        routines introduced by and used in 'perf trace' work. (Jiri Olsa)

      Infrastructure changes:

      - Export init/exit_probe_symbol_maps() from 'perf probe' for use in eBPF.
        (Namhyung Kim)

      - Free perf_probe_event in cleanup_perf_probe_events(). (Namhyung Kim)

      - regs_query_register_offset() infrastructure + implementation for x86.

      dax: fix O_DIRECT I/O to the last block of a blockdev

      commit bbab37ddc20b (block: Add support for DAX reads/writes to
      block devices) caused a regression in mkfs.xfs.  That utility
      sets the block size of the device to the logical block size
      using the BLKBSZSET ioctl, and then issues a single sector read
      from the last sector of the device.  This results in the dax_io
      code trying to do a page-sized read from 512 bytes from the end
      of the device.  The result is -ERANGE being returned to userspace.

      The fix is to align the block to the page size before calling
      get_block.

      Thanks to willy for simplifying my original patch.

      fm10k: fix iov_msg_mac_vlan_pf VID checks

      The VF will send a message to request multicast addresses with the
      default VID. In the current code, if the PF has statically assigned a
      VLAN to a VF, then the VF will not get the multicast addresses. Fix up
      all of the various VLAN messages to use identical checks (since each
      check was different). Also use set as a variable, so that it simplifies
      our check for whether VLAN matches the pf_vid.

      The new logic will allow set of a VLAN if it is zero, automatically
      converting to the default VID. Otherwise it will allow setting the PF
      VID, or any VLAN if PF has not statically assigned a VLAN. This is
      consistent behavior, and allows VF to request either 0 or the
      default_vid without silently failing.

      Note that we need the check for zero since VFs might not get the default
      VID message in time to actually request non-zero VLANs.

      fm10k: re-enable VF after a full reset on detection of a Malicious event

      Modify behavior of Malicious Driver Detection events. Presently, the
      hardware disables the VF queues and re-assigns them to the PF. This
      causes the VF in question to continuously Tx hang, because it assumes
      that it can transmit over the queues in question. For transient events,
      this results in continuous logging of malicious events.

      New behavior is to reset the LPORT and VF state, so that the VF will
      have to reset and re-enable itself. This does mean that malicious VFs
      will possibly be able to continue and attempt malicious events again.
      However, it is expected that system administrators will step in and
      manually remove or disable the VF in question.

      fm10k: send traffic on default VID to VLAN device if we have one

      This patch ensures that VLAN traffic on the default VID will go to the
      corresponding VLAN device if it exists. To do this, mask the rx_ring VID
      if we have an active VLAN on that VID.

      For this to work correctly, we need to update fm10k_process_skb_fields
      to correctly mask off the VLAN_PRIO_MASK bits and compare them
      separately, otherwise we incorrectly compare the priority bits with the
      cleared flag. This also happens to fix a related bug where having
      priority bits set causes us to incorrectly classify traffic.

      The way I came about reaching 12K as the desired interrupt rate is by
      testing with UDP flows.  Specifically I had a simple test that ran a
      netperf UDP_STREAM test at varying sizes.  What I found was as the packet
      sizes increased the performance fell steadily behind until we were only
      able to receive at ~4Gb/s with a message size of 65507.  A bit of digging
      found that we were dropping packets for the socket in the network stack,
      and looking at things further what I found was I could solve it by 
increasing
      the interrupt rate, or increasing the rmem_default/rmem_max.  What I 
found was
      that when the interrupt coalescing resulted in more data being processed
      per interrupt than could be stored in the socket buffer we started losing
      packets and the performance dropped.  So I reached 12K based on the
      following math.

      rmem_default = 212992
      skb->truesize = 2994
      212992 / 2994 = 71.14 packets to fill the buffer

      packet rate at 1514 packet size is 812744pps
      71.14 / 812744 = 87.9us to fill socket buffer

      From there it was just a matter of choosing the interrupt rate and
      providing a bit of wiggle room which is why I decided to go with 12K
      interrupts per second as that uses a value of 84us.

      The data below is based on VM to VM over a direct assigned ixgbe 
interface.
      The test run was:
        netperf -H <ip> -t UDP_STREAM"

      ixgbe: Teardown SR-IOV before unregister_netdev()

      When the .remove() callback for a PF is called, SR-IOV support for the
      device is disabled, which requires unbinding and removing the VFs.
      The VFs may be in-use either by the host kernel or userspace, such as
      assigned to a VM through vfio-pci.  In this latter case, the VFs may
      be removed either by shutting down the VM or hot-unplugging the
      devices from the VM.  Unfortunately in the case of a Windows 2012 R2
      guest, hot-unplug is broken due to the ordering of the PF driver
      teardown.  Disabling SR-IOV prior to unregister_netdev() avoids this
      issue.

      openvswitch: Fix mask generation for nested attributes.

      Masks were added to OVS flows in a way that was backwards compatible
      with userspace programs that did not generate masks. As a result, it is
      possible that we may receive flows that do not have a mask and we need
      to synthesize one.

      Generating a mask requires iterating over attributes and descending into
      nested attributes. For each level we need to know the size to generate the
      correct mask. We do this with a linked table of attribute types.

      Although the logic to handle these nested attributes was there in concept,
      there are a number of bugs in practice. Examples include incomplete links
      between tables, variable length attributes being treated as nested and
      missing sanity checks.

      iser-target: Skip data copy if all the command data comes as immediate

      Given that supporting zcopy immediate data for all IOs requires
      iser driver to use its own buffer allocations, we settle with
      avoiding data copy for IOs with data length of up to 8K (which
      is more latency sensitive anyway).

      This trims IO write latency by up to 3us and increase IOPs
      by up to 40% by saving CPU time doing sg_copy_from_buffer
      (8K IO size is the obvious winner here).

      iser-target: Fix pending connections handling in target stack shutdown 
sequnce

      Instead of handing a connection to the iscsi stack
      for processing right after accepting (rdma_accept) we only hand
      the connection to the iscsi core after we reached to a connected
      state (ESTABLISHED CM event). This will prevent two error scenrios:

      1. race between rdma connection teardown and iscsi login sequence
         reported by Nic in: (ce9a9fc20a78a "iser-target: Fix REJECT CM event
         use-after-free OOPs")

      2. target stack shutdown sequence race with constant login attempts by
         multiple initiators.

      We address this by maintaining two queues at the isert_np level:
      - accepted: connections that were accepted but have not reached
        connected state (might get rejected, unreachable or error).
      - pending: connections in connected state, but have yet to handed
        to the iscsi core for login processing. iser connections are promoted
        to the pending queue only from the accepted queue.

      This way the iscsi core now will only handle functional iser connections
      and once we shutdown the target stack, we look for any stales that
      got left behind so we can safely release them.

      iser-target: Put the reference on commands waiting for unsol data

      The iscsi target core teardown sequence calls wait_conn for
      all active commands to finish gracefully by:
      - move the queue-pair to error state
      - drain all the completions
      - wait for the core to finish handling all session commands

      However, when tearing down a session while there are sequenced
      commands that are still waiting for unsolicited data outs, we can
      block forever as these are missing an extra reference put.

      We basically need the equivalent of iscsit_free_queue_reqs_for_conn()
      which is called after wait_conn has returned. Address this by an
      explicit walk on conn_cmd_list and put the extra reference.

      We need to silently finish a command when it's in ISTATE_REMOVE.

      rtnetlink: RTEXT_FILTER_SKIP_STATS support to avoid dumping inet/inet6 
stats

      Many commonly used functions like getifaddrs() invoke RTM_GETLINK
      to dump the interface information, and do not need the
      the AF_INET6 statististics that are always returned by default
      from rtnl_fill_ifinfo().

      Computing the statistics can be an expensive operation that impacts
      scaling, so it is desirable to avoid this if the information is
      not needed.

      This patch adds a the RTEXT_FILTER_SKIP_STATS extended info flag that
      can be passed with netlink_request() to avoid statistics computation
      for the ifinfo path.

      Practically this fixes the PHY not being reliably detected in some cases

      ipv6: Avoid double dst_free

      It is a prep work to get dst freeing from fib tree undergo
      a rcu grace period.

      The following is a common paradigm:
      if (ip6_del_rt(rt))
        dst_free(rt)

      which means, if rt cannot be deleted from the fib tree, dst_free(rt) now.
      1. We don't know the ip6_del_rt(rt) failure is because it
         was not managed by fib tree (e.g. DST_NOCACHE) or it had already been
         removed from the fib tree.
      2. If rt had been managed by the fib tree, ip6_del_rt(rt) failure means
         dst_free(rt) has been called already.  A second
         dst_free(rt) is not always obviously safe.  The rt may have
         been destroyed already.
      3. If rt is a DST_NOCACHE, dst_free(rt) should not be called.
      4. It is a stopper to make dst freeing from fib tree undergo a
         rcu grace period.

      This patch is to use a DST_NOCACHE flag to indicate a rt is
      not managed by the fib tree.

      ipv6: Fix dst_entry refcnt bugs in ip6_tunnel

      Problems in the current dst_entry cache in the ip6_tunnel:

      1. ip6_tnl_dst_set is racy.  There is no lock to protect it:
         - One major problem is that the dst refcnt gets messed up. F.e.
           the same dst_cache can be released multiple times and then
           triggering the infamous dst refcnt < 0 warning message.
         - Another issue is the inconsistency between dst_cache and
           dst_cookie.

         It can be reproduced by adding and removing the ip6gre tunnel
         while running a super_netperf TCP_CRR test.

      2. ip6_tnl_dst_get does not take the dst refcnt before returning
         the dst.

      This patch:
      1. Create a percpu dst_entry cache in ip6_tnl
      2. Use a spinlock to protect the dst_cache operations
      3. ip6_tnl_dst_get always takes the dst refcnt before returning

      drivers: net: cpsw: Add support to drive gpios for ethernet to be 
functional

      In DRA72x EVM, by default slave 1 is connected to the onboard
      phy, but slave 2 pins are also muxed with video input module
      which is controlled by pcf857x gpio and currently to select slave
      0 to connect to phy gpio hogging is used, but with
      omap2plus_defconfig the pcf857x gpio is built as module. So when
      using NFS on DRA72x EVM, board doesn't boot as gpio hogging do
      not set proper gpio state to connect slave 0 to phy as it is
      built as module and you do not see any errors for not setting
      gpio and just mentions dhcp reply not got.

      To solve this issue, introducing "mode-gpios" in DT when gpio
      based muxing is required. This will throw a warning when gpio
      get fails and returns probe defer. When gpio-pcf857x module is
      installed, cpsw probes again and ethernet becomes functional.
      Verified this on DRA72x with pcf as module and ramdisk.

      net: dsa: mv88e6xxx: improve ATU move operations

      This patchset completes the set of available Address Translation Unit
      operations.

      These Marvell switches have 4 operations to flush or (re)move, all or
      only non-static MAC addresses, from the entire set of databases or from
      just a particular one.

      The first 3 patches introduce a generic _mv88e6xxx_atu_flush_move
      function. The 4 remaining patches update a few FID operations in the
      driver on setup, when a port join or leave a VLAN, or change state.

      This is a step forward improving the hardware bridging support in DSA
      and 88E6352-compatible switches.

      net: dsa: mv88e6xxx: rework ATU Flush operation

      These Marvell switches have 4 operations to flush or (re)move, all or
      only non-static MAC addresses, from the entire set of databases or from
      just a particular one.

      The value of the EntryState bits will determine if the operation is
      either a Flush (0x0) or a Move (0xF).

      When moving entries from one port to another, entries will be removed if
      the destination port is 0xF.

      This patch renames these operations for consistency, add a new generic
      _mv88e6xxx_atu_flush_move function, and change _mv88e6xxx_flush_fid to
      use it.

      net: Allow user to get table id from route lookup

      rt_fill_info which is called for 'route get' requests hardcodes the
      table id as RT_TABLE_MAIN which is not correct when multiple tables
      are used. Use the newly added table id in the rtable to send back
      the correct table similar to what is done for IPv6.

      To maintain current ABI a new request flag, RTM_F_LOOKUP_TABLE, is
      added to indicate the actual table is wanted versus the hardcoded
      response.

      PCI: Revert "PCI: Call pci_read_bridge_bases() from core instead of arch 
code"

      Revert dff22d2054b5 ("PCI: Call pci_read_bridge_bases() from core instead
      of arch code").

      Reading PCI bridge windows is not arch-specific in itself, but there is 
PCI
      core code that doesn't work correctly if we read them too early.  For
      example, Hannes found this case on an ARM Freescale i.mx6 board:

        pci_bus 0000:00: root bus resource [mem 0x01000000-0x01efffff]
        pci 0000:00:00.0: PCI bridge to [bus 01-ff]
        pci 0000:00:00.0: BAR 8: no space for [mem size 0x01000000] (mem window)
        pci 0000:01:00.0: BAR 2: failed to assign [mem size 0x00200000]
        pci 0000:01:00.0: BAR 1: failed to assign [mem size 0x00004000]
        pci 0000:01:00.0: BAR 0: failed to assign [mem size 0x00000100]

      The 00:00.0 mem window needs to be at least 3MB: the 01:00.0 device needs
      0x204100 of space, and mem windows are megabyte-aligned.

      Bus sizing can increase a bridge window size, but never *decrease* it (see
      d65245c3297a ("PCI: don't shrink bridge resources")).  Prior to
      dff22d2054b5, ARM didn't read bridge windows at all, so the "original 
size"
      was zero, and we assigned a 3MB window.

      After dff22d2054b5, we read the bridge windows before sizing the bus.  The
      firmware programmed a 16MB window (size 0x01000000) in 00:00.0, and since
      we never decrease the size, we kept 16MB even though we only needed 3MB.
      But 16MB doesn't fit in the host bridge aperture, so we failed to assign
      space for the window and the downstream devices.

      I think this is a defect in the PCI core: we shouldn't rely on the 
firmware
      to assign sensible windows.

      Ray reported a similar problem, also on ARM, with Broadcom iProc.

      Issues like this are too hard to fix right now, so revert dff22d2054b5.

      irqchip/renesas-irqc: Propagate wake-up settings to parent

      The renesas-irqc interrupt controller is cascaded to the GIC, but its
      driver doesn't propagate wake-up settings to the parent interrupt
      controller.

      Since commit aec89ef72ba6c944 ("irqchip/gic: Enable SKIP_SET_WAKE and
      MASK_ON_SUSPEND"), the GIC driver masks interrupts during suspend, and
      wake-up through gpio-keys now fails on r8a73a4/ape6evm.

      Fix this by propagating wake-up settings to the parent interrupt
      controller. There's no need to handle irq_set_irq_wake() failures, as
      the renesas-irqc interrupt controller is always cascaded to a GIC, and
      the GIC driver always sets SKIP_SET_WAKE since the aforementioned
      commit.

      irqchip/GICv2m: Fix GICv2m build warning on 32 bits

      After GICv2m was enabled for 32-bit ARM kernel, a warning popped up:

      drivers/irqchip/irq-gic-v2m.c: In function gicv2m_compose_msi_msg:
      drivers/irqchip/irq-gic-v2m.c:100:2: warning: right shift count >= width
      of type [enabled by default]
        msg->address_hi = (u32) (addr >> 32);
        ^

      This patch fixes it by using proper macros for splitting up the value.

      irqchip/gic-v3-its: Add missing cache flushes

      When the ITS is configured for non-cacheable transactions, make sure
      that the allocated, zeroed memory is flushed to the Point of
      Coherency, allowing the ITS to observe the zeros instead of random
      garbage (or even get its own data overwritten by zeros being evicted
      from the cache...).

      Fixes: 241a386c7dbb "irqchip: gicv3-its: Use non-cacheable accesses when 
no shareability"

      irqchip/GIC: Add workaround for aliased GIC400

      The GICv2 architecture mandates that the two 4kB GIC regions are
      contiguous, and on two separate physical pages (so that access to
      the second page can be trapped by a hypervisor). This doesn't work
      very well when PAGE_SIZE is 64kB.

      A relatively common hack^Wway to work around this is to alias each
      4kB region over its own 64kB page. Of course in this case, the base
      address you want to use is not really the begining of the region,
      but base + 60kB (so that you get a contiguous 8kB region over two
      distinct pages).

      Normally, this would be described in DT with a new property, but
      some HW is already out there, and the firmware makes sure that
      it will override whatever you put in the GIC node. Duh. And of course,
      said firmware source code is not available, despite being based
      on u-boot.

      The workaround is to detect the case where the CPU interface size
      is set to 128kB, and verify the aliasing by checking that the ID
      register for GIC400 (which is the only GIC wired this way so far)
      is the same at base and base + 0xF000. In this case, we update
      the GIC base address and let it roll.

      And if you feel slightly sick by looking at this, rest assured that
      I do too...

      platform-msi: Do not cache msi_desc in handler_data

      The current implementation of platform MSI caches the msi_desc
      pointer in irq_data::handler_data. This is a bit silly, as
      we also have irq_data::msi_desc, which is perfectly valid.

      Remove the useless assignment and simplify the whole flow.

      kvm: fix zero length mmio searching

      Currently, if we had a zero length mmio eventfd assigned on
      KVM_MMIO_BUS. It will never be found by kvm_io_bus_cmp() since it
      always compares the kvm_io_range() with the length that guest
      wrote. This will cause e.g for vhost, kick will be trapped by qemu
      userspace instead of vhost. Fixing this by using zero length if an
      iodevice is zero length.

      kvm: fix double free for fast mmio eventfd

      We register wildcard mmio eventfd on two buses, once for KVM_MMIO_BUS
      and once on KVM_FAST_MMIO_BUS but with a single iodev
      instance. This will lead to an issue: kvm_io_bus_destroy() knows
      nothing about the devices on two buses pointing to a single dev. Which
      will lead to double free[1] during exit. Fix this by allocating two
      instances of iodevs then registering one on KVM_MMIO_BUS and another
      on KVM_FAST_MMIO_BUS.

      Since there is a function to set maps, perf_evlist__create_maps() should

      perf evsel: Add own_cpus member

      perf_evlist__propagate_maps() cannot easily tell if an evsel has its own
      cpu map.  To make that simpler, keep a copy of the PMU cpu map and
      adjust the propagation logic accordingly.

      perf evlist: Fix missing thread_map__put in propagate_maps()

      perf_evlist__propagate_maps() incorrectly assumes evsel->threads is NULL
      before reassigning it, but it won't be NULL when perf_evlist__set_maps()
      is used to set different (or NULL) maps.  Thus thread_map__put must be
      used, which works even if evsel->threads is NULL.

      perf evlist: Fix splice_list_tail() not setting evlist

      Commit d49e46950772 ("perf evsel: Add a backpointer to the evlist a
      evsel is in") updated perf_evlist__add() but not
      perf_evlist__splice_list_tail().

      This illustrates that it is better if perf_evlist__splice_list_tail()
      calls perf_evlist__add() instead of duplicating the logic, so do that.
      This will also simplify a subsequent fix for propagating maps.

      perf evlist: Remove redundant validation from propagate_maps()

      The validation checks that the values that were just assigned, got
      assigned i.e. the error can't ever happen.  Subsequent patches will call
      this code in places where errors are not being returned.  Changing those
      code paths to return this non-existent error is counter-productive, so
      just remove it.

      That in turn results in perf_evlist__set_maps not needing to return an
      error, but callers aren't checking it either, so remove that too.

      cxl: Fix build failure due to -Wunused-variable behaviour change

      A recent change in gcc caused this build failure:

      
/var/lib/jenkins/workspace/gcc_kernel_build/linux/drivers/misc/cxl/cxl.h:72:27:
      error: â??CXL_PSL_DLCNTLâ?? defined but not used 
[-Werror=unused-const-variable]
       static const cxl_p1_reg_t CXL_PSL_DLCNTL  = {0x0060};

      Because of this gcc commit:

      Commit 1bca8cbd0c68366f07277f98ce6963e10c2aa617 by mark
      PR28901 -Wunused-variable ignores unused const initialised variables in C
      12 years ago it was decided that -Wunused-variable shouldn't warn about
      static const variables because some code used const static char rcsid[]
      strings which were never used but wanted in the code anyway. But as the
      bug points out this hides some real bugs. These days the usage of
      rcsids is not very popular anymore. So this patch changes the default
      to warn about unused static const variables in C with
      -Wunused-variable. And it adds a new option -Wno-unused-const-variable
      to turn this warning off. For C++ this new warning is off by default,
      since const variables can be used as #defines in C++. New testcases for
      the new defaults in C and C++ are included testing the new warning and
      suppressing it with an unused attribute or using
      -Wno-unused-const-variable. gcc/ChangeLog

      The cxl driver uses static consts in place of #defines in some cases
      for type safety, so this change causes the driver to fail to build on
      new copilers as these constants are not all used in every file that
      imports the header. Suppress the warning for this driver to return to
      the old behaviour of -Wunused-variable.

      cxl: Fix unbalanced pci_dev_get in cxl_probe

      Currently the first thing we do in cxl_probe is to grab a reference
      on the pci device. Later on, we call device_register on our adapter.
      In our remove path, we call device_unregister, but we never call
      pci_dev_put. We therefore leak the device every time we do a
      reflash.

      device_register/unregister is sufficient to hold the reference.
      Therefore, drop the call to pci_dev_get.

      Here's why this is safe.
      The proposed cxl_probe(pdev) calls cxl_adapter_init:
          a) init calls cxl_adapter_alloc, which creates a struct cxl,
             conventionally called adapter. This struct contains a
             device entry, adapter->dev.

          b) init calls cxl_configure_adapter, where we set
             adapter->dev.parent = &dev->dev (here dev is the pci dev)

      So at this point, the cxl adapter's device's parent is the PCI
      device that I want to be refcounted properly.

          c) init calls cxl_register_adapter
             *) cxl_register_adapter calls device_register(&adapter->dev)

      So now we're in device_register, where dev is the adapter device, and
      we want to know if the PCI device is safe after we return.

      device_register(&adapter->dev) calls device_initialize() and then
      device_add().

      device_add() does a get_device(). device_add() also explicitly grabs
      the device's parent, and calls get_device() on it:

               parent = get_device(dev->parent);

      So therefore, device_register() takes a lock on the parent PCI dev,
      which is what pci_dev_get() was guarding. pci_dev_get() can therefore
      be safely removed.

      usb: chipidea: udc: using the correct stall implementation

      According to spec, there are functional and protocol stalls.

      For functional stall, it is for bulk and interrupt endpoints,
      below are cases for it:
      - Host sends SET_FEATURE request for Set-Halt, the udc driver
      needs to set stall, and return true unconditionally.
      - The gadget driver may call usb_ep_set_halt to stall certain
      endpoints, if there is a transfer in pending, the udc driver
      should not set stall, and return -EAGAIN accordingly.
      These two kinds of stall need to be cleared by host using CLEAR_FEATURE
      request (Clear-Halt).

      For protocol stall, it is for control endpoint, this stall will
      be set if the control request has failed. This stall will be
      cleared by next setup request (hardware will do it).

      It fixed usbtest (drivers/usb/misc/usbtest.c) Test 13 "set/clear halt"
      test failure, meanwhile, this change has been verified by
      USB2 CV Compliance Test and MSC Tests.

      drm/ttm: Fix memory space allocation v2

      In the event that TTM doesn't find a compatible memory type for the
      driver's first placement choice (placement without eviction), TTM
      returns -EINVAL without trying the driver's second choice.
      This causes problems on vmwgfx when VRAM is disabled before first modeset
      and during VT switches when fbdev is not enabled.

      Fix this by also trying the driver's second choice before returning
      -EINVAL.

      v2: Also check that man->use_type is true for the driver's second choice.
      Fixes a bug where disallowed memory types could be used.

      btrfs: skip waiting on ordered range for special files

      In btrfs_evict_inode, we properly truncate the page cache for evicted
      inodes but then we call btrfs_wait_ordered_range for every inode as well.
      It's the right thing to do for regular files but results in incorrect
      behavior for device inodes for block devices.

      filemap_fdatawrite_range gets called with inode->i_mapping which gets
      resolved to the block device inode before getting passed to
      wbc_attach_fdatawrite_inode and ultimately to inode_to_bdi.  What happens
      next depends on whether there's an open file handle associated with the
      inode.  If there is, we write to the block device, which is unexpected
      behavior.  If there isn't, we through normally and inode->i_data is used.
      We can also end up racing against open/close which can result in crashes
      when i_mapping points to a block device inode that has been closed.

      Since there can't be any page cache associated with special file inodes,
      it's safe to skip the btrfs_wait_ordered_range call entirely and avoid
      the problem.

      Btrfs: fix read corruption of compressed and shared extents

      If a file has a range pointing to a compressed extent, followed by
      another range that points to the same compressed extent and a read
      operation attempts to read both ranges (either completely or part of
      them), the pages that correspond to the second range are incorrectly
      filled with zeroes.

      Consider the following example:

        File layout
        [0 - 8K]                      [8K - 24K]
            |                             |
            |                             |
         points to extent X,         points to extent X,
         offset 4K, length of 8K     offset 0, length 16K

        [extent X, compressed length = 4K uncompressed length = 16K]

      If a readpages() call spans the 2 ranges, a single bio to read the extent
      is submitted - extent_io.c:submit_extent_page() would only create a new
      bio to cover the second range pointing to the extent if the extent it
      points to had a different logical address than the extent associated with
      the first range. This has a consequence of the compressed read end io
      handler (compression.c:end_compressed_bio_read()) finish once the extent
      is decompressed into the pages covering the first range, leaving the
      remaining pages (belonging to the second range) filled with zeroes (done
      by compression.c:btrfs_clear_biovec_end()).

      So fix this by submitting the current bio whenever we find a range
      pointing to a compressed extent that was preceded by a range with a
      different extent map. This is the simplest solution for this corner
      case. Making the end io callback populate both ranges (or more, if we
      have multiple pointing to the same extent) is a much more complex
      solution since each bio is tightly coupled with a single extent map and
      the extent maps associated to the ranges pointing to the shared extent
      can have different offsets and lengths.

      The following test case for fstests triggers the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$
        status=1        # failure is the default!
        trap "_cleanup; exit \$status" 0 1 2 3 15

            rm -f $tmp.*

      selftests: rename jump label to static_keys

      Commit 2bf9e0ab08c6 ("locking/static_keys: Provide a selftest")
      renamed jump_label directory to static_keys and failed to update
      the Makefile, causing the selftests build to fail.

      This commit fixes it by updating the Makefile with the new name
      and also moves the entry into the correct position to keep the
      list alphabetically sorted.

      This adds support for s390 to the seccomp selftests. Some improvements
      were made to enhance the accuracy of failure reporting, and additional
      tests were added to validate assumptions about the currently traced
      syscall. Also adds early asserts for running on older kernels to avoid

      ARM: dts: Fix dm814x control base to properly initialize Ethernet PHY

      Looks like I made a typo on the control base, all the 81xx
      SoCs have it at 0x48140000 base. We've just gotten away with
      the typo as the Ethernet phy was configured by the bootloader
      on my test system and we're not yet using the pinctrl.

      In addition to fixing the contol base, we need to also use the
      right Ethernet phy flags to initialize it. And we are still
      missing the PLL driver for dm814x and only relying on the
      divider and mux clocks.

      ASoC: mediatek: Increase periods_min in capture

      In capture, there is chance that hw_ptr reported at IRQ is
      a little smaller than period_size due to internal AFE buffer.
      In the case of ping-pong buffer:

      |xxxxxxxxxxxxxxxxxxxxxxxxxxxx--|-----------------------------|
                                  hw_ptr < period_size

      This available buffer will not be read since its size is smaller than
      avail_min (which is period_size by default), and read thread continues
      to sleep. If the next hw_ptr is just a little larger than buffer_size,
      overrun occurs. One more period can hold the possible unread buffer.

      x86/apic: Serialize LVTT and TSC_DEADLINE writes

      The APIC LVTT register is MMIO mapped but the TSC_DEADLINE register is an
      MSR. The write to the TSC_DEADLINE MSR is not serializing, so it's not
      guaranteed that the write to LVTT has reached the APIC before the
      TSC_DEADLINE MSR is written. In such a case the write to the MSR is
      ignored and as a consequence the local timer interrupt never fires.

      The SDM decribes this issue for xAPIC and x2APIC modes. The
      serialization methods recommended by the SDM differ.

      xAPIC:
       "1. Memory-mapped write to LVT Timer Register, setting bits 18:17 to 10b.
        2. WRMSR to the IA32_TSC_DEADLINE MSR a value much larger than current 
time-stamp counter.
        3. If RDMSR of the IA32_TSC_DEADLINE MSR returns zero, go to step 2.
        4. WRMSR to the IA32_TSC_DEADLINE MSR the desired deadline."

      x2APIC:
       "To allow for efficient access to the APIC registers in x2APIC mode,
        the serializing semantics of WRMSR are relaxed when writing to the
        APIC registers. Thus, system software should not use 'WRMSR to APIC
        registers in x2APIC mode' as a serializing instruction. Read and write
        accesses to the APIC registers will occur in program order. A WRMSR to
        an APIC register may complete before all preceding stores are globally
        visible; software can prevent this by inserting a serializing
        instruction, an SFENCE, or an MFENCE before the WRMSR."

      The xAPIC method is to just wait for the memory mapped write to hit
      the LVTT by checking whether the MSR write has reached the hardware.
      There is no reason why a proper MFENCE after the memory mapped write would
      not do the same. Andi Kleen confirmed that MFENCE is sufficient for the
      xAPIC case as well.

      Issue MFENCE before writing to the TSC_DEADLINE MSR. This can be done
      unconditionally as all CPUs which have TSC_DEADLINE also have MFENCE
      support.

      x86/ioapic: Force affinity setting in setup_ioapic_dest()

      The recent ioapic cleanups changed the affinity setting in
      setup_ioapic_dest() from a direct write to the hardware to the delayed
      affinity setup via irq_set_affinity().

      That results in a warning from chained_irq_exit():
      WARNING: CPU: 0 PID: 5 at kernel/irq/migration.c:32 irq_move_masked_irq
      [<ffffffff810a0a88>] irq_move_masked_irq+0xb8/0xc0
      [<ffffffff8103c161>] ioapic_ack_level+0x111/0x130
      [<ffffffff812bbfe8>] intel_gpio_irq_handler+0x148/0x1c0

      The reason is that irq_set_affinity() does not write directly to the
      hardware. It marks the affinity setting as pending and executes it
      from the next interrupt. The chained handler infrastructure does not
      take the irq descriptor lock for performance reasons because such a
      chained interrupt is not visible to any interfaces. So the delayed
      affinity setting triggers the warning in irq_move_masked_irq().

      Restore the old behaviour by calling the set_affinity function of the
      ioapic chip in setup_ioapic_dest(). This is safe as none of the
      interrupts can be on the fly at this point.

      netfilter: nft_compat: skip family comparison in case of NFPROTO_UNSPEC

      Fix lookup of existing match/target structures in the corresponding list
      by skipping the family check if NFPROTO_UNSPEC is used.

      This is resulting in the allocation and insertion of one match/target
      structure for each use of them. So this not only bloats memory
      consumption but also severely affects the time to reload the ruleset
      from the iptables-compat utility.

      dm crypt: constrain crypt device's max_segment_size to PAGE_SIZE

      Setting the dm-crypt device's max_segment_size to PAGE_SIZE is an
      unfortunate constraint that is required to avoid the potential for
      exceeding dm-crypt's underlying device's max_segments limits -- due to
      crypt_alloc_buffer() possibly allocating pages for the encryption bio
      that are not as physically contiguous as the original bio.

      It is interesting to note that this problem was already fixed back in
      2007 via commit 91e106259 ("dm crypt: use bio_add_page").  But Linux 4.0
      commit cf2f1abfb ("dm crypt: don't allocate pages for a partial
      request") regressed dm-crypt back to _not_ using bio_add_page().  But
      given dm-crypt's cpu parallelization changes all depend on commit
      cf2f1abfb's abandoning of the more complex io fragments processing that
      dm-crypt previously had we cannot easily go back to using
      bio_add_page().

      So all said the cleanest way to resolve this issue is to fix dm-crypt to
      properly constrain the original bios entering dm-crypt so the encryption
      bios that dm-crypt generates from the original bios are always
      compatible with the underlying device's max_segments queue limits.

      It should be noted that technically Linux 4.3 does _not_ need this fix
      because of the block core's new late bio-splitting capability.  But, it
      is reasoned, there is little to be gained by having the block core split
      the encrypted bio that is composed of PAGE_SIZE segments.  That said, in
      the future we may revert this change.

      perf machine: Add pointer to sample's environment

      The 'struct machine' represents the machine where the samples were/are
      being collected, and we also have a 'struct perf_env' with extra details
      about such machine, that we were collecting at 'perf.data' creation time
      but we also needed when no perf.data file is being used, such as in
      'perf top'.

      So, get those structs closer together, as they provide a bigger picture
      of the sample's environment.

      In 'perf session', when the file argument is NULL, we can assume that
      the tool is sampling the running machine, so point machine->env to
      the global put in place in previous patches, while set it to the
      perf_header.env one when reading from a file.

      This paves the way for machine->env to be used in
      perf_event__preprocess_sample to populate addr_location.socket.

      perf cpu_map: Use sysfs__read_int in get_{core,socket}_id()

      We have the tools/lib/ sysfs__read_int() for that, avoid code
      duplication.

  Date:   Thu Sep 10 12:20:14 2015 -0300

      tools lib api cpu: Introduce cpu.[ch] to obtain cpu related information

      E.g.:

       $ ./cpu__get_max_freq
       3200000

      It does that, as Kan's patch does, by looking at these files:

        $ cat /sys/devices/system/cpu/online
        0-3
        $ ./sysfs__read_ull
        devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
        /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq=3200000
        $

      I.e. find out the first online CPU, then read its cpufreq info.

      But do it in tools/lib/api/, so that other tools/ living code can use
      it, not just perf.

      perf tests: Introduce iterator function for tests

      In preparation for introducing more arrays of tests, e.g. "arch tests"
      (architecture-specific tests), abstract the code to iterate over the
      list of tests into a helper function.

      This way, code that uses a 'struct test' doesn't need to worry about how
      the tests are grouped together and changes to the list of tests doesn't
      require changes to the code using it.

      KVM: arm64: add workaround for Cortex-A57 erratum #852523

      When restoring the system register state for an AArch32 guest at EL2,
      writes to DACR32_EL2 may not be correctly synchronised by Cortex-A57,
      which can lead to the guest effectively running with junk in the DACR
      and running into unexpected domain faults.

      This patch works around the issue by re-ordering our restoration of the
      AArch32 register aliases so that they happen before the AArch64 system
      registers. Ensuring that the registers are restored in this order
      guarantees that they will be correctly synchronised by the core.

      The change ensures otg is not in a A- state when checking for VBUS in
      peripheral mode.

      musb_start() where VBUS checking is in can be called in many situations.
      One example is in babble recovery routine, in which otg is transitioning
      from A-HOST to A-WAIT-BCON, but VBUS discharge takes time, so
      musb->is_active could be set to 1 due to this improper checking, then it
      causes musb_bus_suspend() failed which leads to warning log message

      The power allocator governor currently requires that the thermal zone

      The power allocator governor currently requires that a sustainable power
      is passed as part of the thermal zone's thermal zone parameters.  If
      that parameter is not provided, it doesn't register with the thermal
      zone.

      While this parameter is strongly recommended for optimal performance, it
      doesn't need to be mandatory.  Relax the requirement and allow the
      governor to bind to thermal zones that don't provide it by estimating it
      from the cooling devices' power model.

      x86/platform/uv: Implement simple dump failover if kdump fails

      The ability to trigger a kdump using the system NMI command
      was added by

          commit 12ba6c990fab ("x86/UV: Add kdump to UV NMI handler")
          Author: Mike Travis <travis@xxxxxxx>
          Date:   Mon Sep 23 16:25:03 2013 -0500

      This is useful because when kdump is working the information
      gathered is more informative than the original per CPU stack
      traces or "dump" option.  However a number of things can go
      wrong with kdump and then the stack traces are more useful than
      nothing.

      The two most common reasons for kdump to not be available are:

        1) if a problem occurs during boot before the kdump service is
           started, or
        2) the kdump daemon failed to start.

      In either case the call to crash_kexec() returns unexpectedly.

      When this happens uv_nmi_kdump() also sets the
      uv_nmi_kexec_failed flag which causes the slave CPU's to also
      return to the NMI handler. Upon this unexpected return to the
      NMI handler, the NMI handler will revert to the "dump" action
      which uses show_regs() to obtain a process trace dump for all
      the CPU's.

      Other minor changes:
          The "dump" action now generates both the show_regs() stack trace
          and show instruction pointer information.  Whereas the "ips"
          action only shows instruction pointers for non-idle CPU's.  This
          is more like an abbreviated "ps" display.

      arm64: Fix pte_modify() to preserve the hardware dirty information

      The pte_modify() function with hardware AF/DBM enabled must transfer the
      hardware dirty information to the software PTE_DIRTY bit. However, it
      was setting this bit in newprot and the mask does not cover such bit.
      This patch sets PTE_DIRTY on the original pte which will be preserved in
      the returned value.

      arm64: Fix the pte_hw_dirty() check when AF/DBM is enabled

      Commit 2f4b829c625e ("arm64: Add support for hardware updates of the
      access and dirty pte bits") introduced support for handling hardware
      updates of the access flag and dirty status. The PTE is automatically
      dirtied in hardware (if supported) by clearing the PTE_RDONLY bit when
      the PTE_DBM/PTE_WRITE bit is set. The pte_hw_dirty() macro was added to
      detect a hardware dirtied pte. The pte_dirty() macro checks for both
      software PTE_DIRTY and pte_hw_dirty().

      Functions like pte_modify() clear the PTE_RDONLY bit since it is meant
      to be set in set_pte_at() when written to memory. In such cases,
      pte_hw_dirty() would return true even though such pte is clean. This
      patch changes pte_hw_dirty() to test the PTE_DBM/PTE_WRITE bit together
      with PTE_RDONLY.

access and dirty pte bits")

      arm64: dma-mapping: check whether cma area is initialized or not

      If CMA is turned on and CMA size is set to zero, kernel should
      behave as if CMA was not enabled at compile time.
      Every dma allocation should check existence of cma area
      before requesting memory.

      Arm has done this by commit e464ef16c4f0 ("arm: dma-mapping: add
      checking cma area initialized"), also do this for arm64.

      x86/fpu: Check CPU-provided sizes against struct declarations

      We now have C structures defined for each of the XSAVE state
      components that we support.  This patch adds checks during our
      verification pass to ensure that the CPU-provided data
      enumerated in CPUID leaves matches our C structures.

      If not, we warn and dump all the XSAVE CPUID leaves.

      Note: this *actually* found an inconsistency with the MPX
      'bndcsr' state.  The hardware pads it out differently from
      our C structures.  This patch caught it and warned.

      x86/fpu: Check to ensure increasing-offset xstate offsets

      The xstate CPUID leaves enumerate where each state component is
      inside the XSAVE buffer, along with the size of the entire
      buffer.  Our new XSAVE sanity-checking code extrapolates an
      expected _total_ buffer size by looking at the last component
      that it encounters.

      That method requires that the highest-numbered component also
      be the one with the highest offset.  This is a pretty safe
      assumption, but let's add some code to ensure it stays true.

      To make this check work correctly, we also need to ensure we
      only consider the offsets from enabled features because the
      offset register (ebx) will return 0 on unsupported features.

      This also means that we will preserve the -1's that we
      initialized xstate_offsets/sizes[] with.  That will help
      find bugs.

      x86/fpu: Correct and check XSAVE xstate size calculations

      Note: our xsaves support is currently broken and disabled.  This
      patch does not fix it, but it is an incremental improvement.

      This might be useful to someone backporting the entire set of
      XSAVES patches at some point, but it should not be backported
      alone.

      Ingo said he wanted something like this (bullets 2 and 3):

        http://lkml.kernel.org/r/20150808091508.GB32641@xxxxxxxxx

      There are currently two xsave buffer formats: standard and
      compacted.  The standard format is waht 'XSAVE' and 'XSAVEOPT'
      produce while 'XSAVES' and 'XSAVEC' produce a compacted-formet
      buffer.  (The kernel never uses XSAVEC)

      But, the XSAVES buffer *ALSO* contains "system state components"
      which are never saved by a plain XSAVE.  So, XSAVES has two
      things that might make its buffer differently-sized from an
      XSAVE-produced one.

      The current code assumes that an XSAVES buffer's size is simply
      the sum of the sizes of the (user) states which are supported.
      This seems to work in most cases, but it is not consistent with
      what the SDM says, and it breaks if we 'align' a component in
      the buffer.  The calculation is also unnecessary work since the
      CPU *tells* us the size of the buffer directly.

      This patch just reads the size of the buffer right out of the
      CPUID leaf instead of trying to derive it.

      But, blindly trusting the CPU like this is dangerous.  We add
      a verification pass in do_extra_xstate_size_checks() to ensure
      that the size we calculate matches with what we see from the
      hardware.  When it comes down to it, we trust but verify the
      CPU.

      x86/fpu: Add C structures for AVX-512 state components

      AVX-512 has 3 separate state components:

        1. opmask registers
        2. zmm upper half of registers 0-15
        3. new zmm registers (16-31)

      This patch adds C structures for the three components along with
      a few comments mostly lifted from the SDM to explain what they
      do.  This will allow us to check our structures against what the
      hardware tells us about the sizes of the components.

      against our structures and need them to match.  For consistency,
      we also ensure to prefix these types with 'mpx_'.

      x86/fpu: Add xfeature_enabled() helper instead of test_bit()

      We currently use test_bit() in a few places to see if an
      xfeature is enabled.  It ends up being a bit ugly because
      'xfeatures_mask' is a u64 and test_bit wants an 'unsigned long'
      so it requires a cast.  The *_bit() functions are also
      techincally atomic, which we have no need for here.

      So, remove the test_bit()s and replace with the new
      xfeature_enabled() helper.

      This also provides a central place to add a comment about the
      future need to support 'system xstates'.

      x86/fpu: Remove 'xfeature_nr'

      xfeature_nr ended up being initialized too late for me to
      use it in the "xsave size sanity check" patch which is
      later in the series.  I tried to move around its initialization
      but realized that it was just as easy to get rid of it.

      We only have 9 XFEATURES.  Instead of dynamically calculating
      and storing the last feature, just use the compile-time max:
      XFEATURES_NR_MAX.  Note that even with 'xfeatures_nr' we can
      had "holes" in the xfeatures_mask that we had to deal with.

      We also change a 'leaf' variable to be a plain 'i'.  Although
      it is used to grab a cpuid leaf in this one loop, all of the
      other loops just use an 'i' and I find it much more obvious
      to keep the naming consistent across all the similar loops.

      The 'xstate.c' code has a bunch of references to '2'.  This

      x86/fpu: Rename XSAVE macros

      There are two concepts that have some confusing naming:
       1. Extended State Component numbers (currently called
          XFEATURE_BIT_*)
       2. Extended State Component masks (currently called XSTATE_*)

      The numbers are (currently) from 0-9.  State component 3 is the
      bounds registers for MPX, for instance.

      But when we want to enable "state component 3", we go set a bit
      in XCR0.  The bit we set is 1<<3.  We can check to see if a
      state component feature is enabled by looking at its bit.

      The current 'xfeature_bit's are at best xfeature bit _numbers_.
      Calling them bits is at best inconsistent with ending the enum
      list with 'XFEATURES_NR_MAX'.

      This patch renames the enum to be 'xfeature'.  These also
      happen to be what the Intel documentation calls a "state
      component".

      We also want to differentiate these from the "XSTATE_*" macros.
      The "XSTATE_*" macros are a mask, and we rename them to match.

      These macros are reasonably widely used so this patch is a

      x86/ldt: Fix small LDT allocation for Xen

      While the following commit:

        37868fe113 ("x86/ldt: Make modify_ldt synchronous")

      added a nice comment explaining that Xen needs page-aligned
      whole page chunks for guest descriptor tables, it then
      nevertheless used kzalloc() on the small size path.

      As I'm unaware of guarantees for kmalloc(PAGE_SIZE, ) to return
      page-aligned memory blocks, I believe this needs to be switched
      back to __get_free_page() (or better get_zeroed_page()).

      x86/fpu: Remove XSTATE_RESERVE

      The original purpose of XSTATE_RESERVE was to carve out space
      to store all of the possible extended state components that
      get saved with the XSAVE instruction(s).

      However, we are now almost entirely dynamically allocating
      the buffers we use for XSAVE by placing them at the end of
      the task_struct and them sizing them at boot.  The one
      exception for that is the init_task.

      The maximum extended state component size that we have today
      is on systems with space for AVX-512 and Memory Protection
      Keys: 2696 bytes.  We have reserved a PAGE_SIZE buffer in
      the init_task via fpregs_state->__padding.

      This check ensures that even if the component sizes or
      layout were changed (which we do not expect), that we will
      still not overflow the init_task's buffer.

      In the case that we detect we might overflow the buffer,
      we completely disable XSAVE support in the kernel and try
      to boot as if we had 'legacy x87 FPU' support in place.
      This is a crippled state without any of the XSAVE-enabled
      features (MPX, AVX, etc...).  But, it at least let us
      boot safely.

      x86/fpu: Move XSAVE-disabling code to a helper

      When we want to _completely_ disable XSAVE support as far as
      the kernel is concerned, we have a big set of feature flags
      to clear.  We currently only do this in cases where the user
      asks for it to be disabled, but we are about to expand the
      places where we do it to handle errors too.

      Move the code in to xstate.c, and put it in the xstate.h
      header.  We will use it in the next patch too.

      acpi/apei: Use appropriate pgprot_t to map GHES memory

      If the ACPI APEI firmware handles hardware error first (called
      "firmware first handling"), the firmware updates the GHES memory
      region with hardware error record (called "generic hardware
      error record"). Essentially the firmware writes hardware error
      records in the GHES memory region, triggers an NMI/interrupt,
      then the GHES driver goes off and grabs the error record from
      the GHES region.

      The kernel currently maps the GHES memory region as cacheable
      (PAGE_KERNEL) for all architectures. However, on some arm64
      platforms, there is a mismatch between how the kernel maps the
      GHES region (PAGE_KERNEL) and how the firmware maps it
      (EFI_MEMORY_UC, ie. uncacheable), leading to the possibility of
      the kernel GHES driver reading stale data from the cache when it
      receives the interrupt.

      With stale data being read, the kernel is unaware there is new
      hardware error to be handled when there actually is; this may
      lead to further damage in various scenarios, such as error
      propagation caused data corruption. If uncorrected error (such
      as double bit ECC error) happened in memory operation and if the
      kernel is unaware of such an event happening, errorneous data may
      be propagated to the disk.

      Instead GHES memory region should be mapped with page protection
      type according to what is returned from arch_apei_get_mem_attribute().

      will likely fail in this case, but it leads to underflow reports on

      kernel instrumented with the size_overflow plugin.

      drm/vmwgfx: Map the fifo as cached

      On the guest kernel side, previously the FIFO has been mapped write-
      combined. This has worked since VMs up to now has not honored the mapping
      type and mapped the FIFO cached anyway. Since the FIFO is accessed cached
      by the CPU on the virtual device side, this leads to inconsistent
      mappings once the guest starts to honor the mapping types.

      So ask for cached mappings when we map the FIFO. We do this by
      using ioremap_cache() instead of ioremap_wc(), and remove the MTRR setup.
      On the TTM side, MOBs, GMRs and VRAM buffers are already requesting
      cached mappings for kernel- and user-space.

      drm/vmwgfx: Fix up user_dmabuf refcounting

      If user space calls unreference on a user_dmabuf it will typically
      kill the struct ttm_base_object member which is responsible for the
      user-space visibility. However the dmabuf part may still be alive and
      refcounted. In some situations, like for shared guest-backed surface
      referencing/opening, the driver may try to reference the
      struct ttm_base_object member again, causing an immediate kernel warning
      and a later kernel NULL pointer dereference.

      Fix this by always maintaining a reference on the struct
      ttm_base_object member, in situations where it might subsequently be
      referenced.

      pinctrl: core: Warn about NULL gpio_chip in pinctrl_ready_for_gpio_range()

      If the gpio driver is confused about the numbers for gpio-ranges,
      pinctrl_ready_for_gpio_range() may get called with invalid GPIO
      causing a NULL pointer exception. Let's instead provide a warning

      drivers: sh: Disable PM runtime for multi-platform ARM with genpd

      If the default PM Domain using PM_CLK is used for PM runtime, the real
      Clock Domain cannot be registered from DT later.

      Hence do not enable it when running a multi-platform kernel with genpd
      support on R-Car or RZ.  The CPG/MSTP Clock Domain driver will take care
      of PM runtime management of the module clocks.

      Now most multi-platform ARM shmobile platforms (SH-Mobile, R-Mobile,
      R-Car, RZ) use DT-based PM Domains to take care of PM runtime management
      of the module clocks, simplify the platform logic by replacing the
      explicit SoC checks by a single check for the presence of MSTP clocks in
      DT.

      Backwards-compatiblity with old DTs (mainly for R-Car Gen2) is provided
      by checking for the presence of a "#power-domain-cells" property in DT.

      The default PM Domain is still needed for:
        - backwards-compatibility with old DTs that lack PM Domain properties,
        - the CONFIG_PM=n case,
        - legacy (non-DT) ARM/shmobile platforms without genpd support
          (r8a7778, r8a7779),
        - legacy SuperH.

      ARM: EXYNOS: reset Little cores when cpu is up

      The cpu booting of exynos5422 has been still broken since we discussed
      it in last year[1]. This patch is inspired from Odroid XU3
      code (Actually, it was from samsung exynos vendor kernel)[2]. This weird
      reset code was founded exynos5420 octa cores series SoCs and only
      required for the first boot core is the Little core (Cortex A7).
      Some of the exynos5420 boards and all of the exynos5422 boards will 
require
      this code.

      There is two ways to check the little core is the first cpu. One is
      checking GPG2CON[1] GPIO value and the other is checking the cluster
      number of the first cpu. I selected the latter because it's more easier
      than the former.

      In cases where visorbus is compiled directly into the kernel, if
      visorbus registration fails for any reason, it is still possible for
      other drivers to call visorbus_register_visor_driver(), which could
      cause an oops. Prevent this by saving the result of the call to

      hasn't been registered successfully.

      staging/android: Update ION TODO per LPC discussion

      We discussed a bit with the folks on the Cc: list below what to do
      with ION. Two big take-aways:

      - High-performance drivers (like gpus) always want to play tricks with
        coherency and will lie to the dma api (radeon, nouveau, i915 gpu
        drivers all do so in upstream). What needs to be done here is fill
        gaps in dma-buf so that we can do this without breaking the dma-api
        expections of other clients like v4l. The consesus is that hw won't
        stop needing these tricks anytime soon.

      - Placement constraints for shared buffers won't be solved any other
        way than through something platform-specific like ion with
        platform-specific knowledge in userspace in something like gralloc.
        For general-purpose devices where this assumption would be painful
        for userspace (like servers) the consensus is that such devices will
        have proper MMUs where placement constraint handling is fairly
        irrelevant.

      Hence it is reasonable to destage ion as-is without changing the
      overall design to enable these use-cases and just fixing up a these
      few fairly minor things. Since there won't relly be an open-source
      userspace for ion (and hence drm maintainers won't take it) the
      proposal is to eventually move it to drivers/android/ion.[hc]. Laura
      would be ok with being maintainer once this is all done and ion is
      destaged.

      Note that Thiago is working on exposing the cpu cache flushing for
      cpu access from userspace through mmaps so this is alread in progress.
      Also adding him to the Cc: list.

      v2: Add ION_IOC_IMPORT to the list of ioctl that probably should go.

      perf header: Fixup reading of HEADER_NRCPUS feature

      The original patch introducing this header wrote the number of CPUs 
available
      and online in one order and then swapped those values when reading, fix 
it.

      Before:

        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 4
        # echo 0 > /sys/devices/system/cpu/cpu2/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 3
        # echo 0 > /sys/devices/system/cpu/cpu1/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 2

      After the fix, bringing back the CPUs online:

        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 2
        # nrcpus avail : 4
        # echo 1 > /sys/devices/system/cpu/cpu2/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 3
        # nrcpus avail : 4
        # echo 1 > /sys/devices/system/cpu/cpu1/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4

      The ddc-i2c-bus property was missing from the veyron dtsi file since
      downstream the ddc-i2c-bus was still being specified in rk3288.dtsi and
      nobody noticed when the veyron dtsi was sent upstream.  Add it.

      ARM: dts: Fix Makefile target for sun4i-a10-itead-iteaduino-plus

      Commit 79ae3e66f8d (ARM: dts: sun4i: Add Iteaduino Plus A10) added a new
      make target for the sun4i-a10-itead-iteaduino-plus dts file, but 
mistakenly
      used .dts instead of the correct .dtb suffix.  This resulted in a build 
error
      like:

              scripts/Makefile.dtbinst:42: target 
'sun4i-a10-itead-iteaduino-plus.dts' doesn't match the target pattern

      when doing a make dtbs_install.

      Fix it to use the proper file name.

      ARM: dts: sunxi: Raise minimum CPU voltage for sun7i-a20 to meet SoC 
specifications

      sun7i-a20.dtsi contains a cpufreq operating point at 0.9 volts. The 
minimum
      CPU voltage for the Allwinner A20 SoC, however, is 1.0 volts. Thus, raise
      the voltage for the lowest operating point to 1.0 volts in order to stay
      within the SoC specifications. It is an undervolted setting that isn't
      stable across all SoCs and boards out there.

      ARM: pxa: ssp: Fix build error by removing originally incorrect DT binding

      Commit 03fbf488cece ("spi: pxa2xx: Differentiate Intel LPSS types") caused
      build error here because it removed the type LPSS_SSP and I didn't notice
      the type was used here too.

      I believe commit a6e56c28a178 ("ARM: pxa: ssp: add DT bindings") added it
      accidentally by copying all enum pxa_ssp_type types from
      include/linux/pxa2xx_ssp.h even LPSS_SSP was for Intel LPSS SPI devices.

      ARM: pxa: fix DFI bus lockups on startup

      After the conversion of pxa architecture to common clock framework, the
      NAND clock can be disabled on startup if no nand driver claims it.

      In this case, it happens that if the bootloader used the NAND and set
      the DFI arbitration bit, the next access to a static memory controller
      area, such as an ethernet card, the system bus will stall, and the core
      will be stalled forever.

      Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit
      will be enabled the pxa3xx-nand driver on need anyway. The only left
      requirement is that upon pxa3xx-nand removal, the bit should be cleared
      before the clock is disabled.

      perf/core: Drop PERF_EVENT_TXN

      We currently use PERF_EVENT_TXN flag to determine if we are in the middle
      of a transaction. If in a transaction, we defer the schedulability checks
      from pmu->add() operation to the pmu->commit() operation.

      Now that we have "transaction types" (PERF_PMU_TXN_ADD, PERF_PMU_TXN_READ)
      we can use the type to determine if we are in a transaction and drop the
      PERF_EVENT_TXN flag.

      When PERF_EVENT_TXN is dropped, the cpuhw->group_flag on some 
architectures
      becomes unused, so drop that field as well.

      This is an extension of the Powerpc patch from Peter Zijlstra to s390,
      Sparc and x86 architectures.

      powerpc, perf/powerpc/hv-24x7: Use PMU_TXN_READ interface

      The 24x7 counters in Powerpc allow monitoring a large number of counters
      simultaneously. They also allow reading several counters in a single
      HCALL so we can get a more consistent snapshot of the system.

      Use the PMU's transaction interface to monitor and read several event
      counters at once. The idea is that users can group several 24x7 events
      into a single group of events. We use the following logic to submit
      the group of events to the PMU and read the values:

        pmu->start_txn()                // Initialize before first event

        for each event in group
                pmu->read(event);       // Queue each event to be read

        pmu->commit_txn()               // Read/update all queuedcounters

      The ->commit_txn() also updates the event counts in the respective
      perf_event objects.  The perf subsystem can then directly get the
      event counts from the perf_event and can avoid submitting a new
      ->read() request to the PMU.

      Thanks to input from Peter Zijlstra.

      perf/core: Define PERF_PMU_TXN_READ interface

      Define a new PERF_PMU_TXN_READ interface to read a group of counters
      at once.

              pmu->start_txn()                // Initialize before first event

              for each event in group
                      pmu->read(event);       // Queue each event to be read

              rc = pmu->commit_txn()          // Read/update all queued counters

      Note that we use this interface with all PMUs.  PMUs that implement this
      interface use the ->read() operation to _queue_ the counters to be read
      and use ->commit_txn() to actually read all the queued counters at once.

      PMUs that don't implement PERF_PMU_TXN_READ ignore ->start_txn() and
      ->commit_txn() and continue to read counters one at a time.

      When we implement the ability to read several counters at once (using

      perf/core: Split perf_event_read() and perf_event_count()

      perf_event_read() does two things:

        - call the PMU to read/update the counter value, and
        - compute the total count of the event and its children

      Not all callers need both. perf_event_reset() for instance needs the
      first piece but doesn't need the second.  Similarly, when we implement
      the ability to read a group of events using the transaction interface,
      we would need the two pieces done independently.

      Break up perf_event_read() and have it just read/update the counter
      and have the callers compute the total count if necessary.

      perf/core: Add a 'flags' parameter to the PMU transactional interfaces

      Currently, the PMU interface allows reading only one counter at a time.
      But some PMUs like the 24x7 counters in Power, support reading several
      counters at once. To leveage this functionality, extend the transaction
      interface to support a "transaction type".

      The first type, PERF_PMU_TXN_ADD, refers to the existing transactions,
      i.e. used to _schedule_ all the events on the PMU as a group. A second
      transaction type, PERF_PMU_TXN_READ, will be used in a follow-on patch,
      by the 24x7 counters to read several counters at once.

      Extend the transaction interfaces to the PMU to accept a 'txn_flags'
      parameter and use this parameter to ignore any transactions that are
      not of type PERF_PMU_TXN_ADD.

      Thanks to Peter Zijlstra for his input.

      perf/x86/intel/pt: Fix KVM warning due to doing rdmsr() before the CPUID 
test

      If KVM does not support INTEL_PT, guest MSR_IA32_RTIT_CTL reading will
      produce host warning like "kvm [2469]: vcpu0 unhandled rdmsr: 0x570".

      Guest can determine whether the CPU supports Intel_PT according to CPUID,
      so test_cpu_cap function is added before rdmsr,and it is more in line with
      the code style.

      perf/x86/intel: Fix LBR callstack issue caused by FREEZE_LBRS_ON_PMI

      This patch fixes an issue which introduced by commit
      1a78d93750bb5f61abdc59a91fc3bd06a214542a ("perf/x86/intel: Streamline
      LBR MSR handling in PMI").

      The old patch not only avoids writing LBR_SELECT MSR in PMI, but also
      avoids updating lbr_select variable. So in PMI, FREEZE_LBRS_ON_PMI bit
      is always mistakenly set for IA32_DEBUGCTLMSR MSR, which causes
      superfluous increase/decrease of LBR_TOS when collecting LBR callstack.

      perf/x86/intel/bts: Disallow use by unprivileged users on paranoid systems

      BTS leaks kernel addresses even in userspace-only mode due to imprecise IP
      sampling, so sometimes syscall entry points or page fault handler 
addresses
      end up in a userspace trace.

      Now, intel_bts driver exports trace data zero-copy, it does not scan 
through
      it to filter out the kernel addresses and it's would be a O(n) job.

      To work around this situation, this patch forbids the use of intel_bts
      driver by unprivileged users on systems with the paranoid setting above 
the
      (kernel's) default "1", which still allows kernel profiling. In other 
words,
      using intel_bts driver implies kernel tracing, regardless of the
      "exclude_kernel" attribute setting.

      perf/x86/intel/ds: Work around BTS leaking kernel addresses

      BTS leaks kernel addresses even in userspace-only mode due to imprecise IP
      sampling, so sometimes syscall entry points or page fault handler 
addresses
      end up in a userspace trace.

      Since this driver uses a relatively small buffer for BTS records and it 
has
      to iterate through them anyway, it can also take on the additional job of
      filtering out the records that contain kernel addresses when kernel space
      tracing is not enabled.

      This patch changes the bts code to skip the offending records from perf
      output. In order to request the exact amount of space on the ring buffer,
      we need to do an extra pass through the records to know how many there are
      of the valid ones, but considering the small size of the buffer, this 
extra
      pass adds very little overhead to the nmi handler. This way we won't end
      up with awkward IP samples with zero IPs in the perf stream.

      perf/x86: Improve accuracy of perf/sched clock

      When TSC is stable perf/sched clock is based on it.
      However the conversion from cycles to nanoseconds
      is not as accurate as it could be.  Because
      CYC2NS_SCALE_FACTOR is 10, the accuracy is +/- 1/2048

      The change is to calculate the maximum shift that
      results in a multiplier that is still a 32-bit number.
      For example all frequencies over 1 GHz will have
      a shift of 32, making the accuracy of the conversion
      +/- 1/(2^33).  That is achieved by using the
      'clocks_calc_mult_shift()' function.

      Architectures may only provide {cmp,}xchg_relaxed definitions in

      linux/atomic.h, which means simply including asm/cmpxchg.h may not get
      the definitions of all the{cmp,}xchg variants.

      Therefore, we should privatize the inclusions of asm/cmpxchg.h to
      keep it only included in arch/* and replace the inclusions outside
      with linux/atomic.h

  Date:   Wed Sep 9 16:07:30 2015 -0700

      time: Fix timekeeping_freqadjust()'s incorrect use of abs() instead of 
abs64()

      The internal clocksteering done for fine-grained error
      correction uses a logarithmic approximation, so any time
      adjtimex() adjusts the clock steering, timekeeping_freqadjust()
      quickly approximates the correct clock frequency over a series
      of ticks.

      Unfortunately, the logic in timekeeping_freqadjust(), introduced
      in commit:

        dc491596f639 ("timekeeping: Rework frequency adjustments to work better 
w/ nohz")

      used the abs() function with a s64 error value to calculate the
      size of the approximated adjustment to be made.

      Per include/linux/kernel.h:

        "abs() should not be used for 64-bit types (s64, u64, long long) - use 
abs64()".

      Thus on 32-bit platforms, this resulted in the clocksteering to
      take a quite dampended random walk trying to converge on the
      proper frequency, which caused the adjustments to be made much
      slower then intended (most easily observed when large
      adjustments are made).

      This patch fixes the issue by using abs64() instead.

      sched/fair: Optimize per entity utilization tracking

      Currently the load_{sum,avg} and util_{sum,avg} tracking is asymmetric
      in that load tracking gets a 2^10 unit from the weight, but util gets
      no such factor.

      This results in more lost bits for util scaling and asymmetric scaling
      rules.

      Fix this by removing shifts, such that we gain the 2^10 factor from
      scaling. There is no risk of overflowing the u32 as the max value is
      now LOAD_AVG_MAX << 10, which is still well below UINT_MAX.

      This further entangles the assumption that both LOAD and CAPACITY
      shifts are the same (and 10) so put in an assertion for that.

      This fixes the math for the LOAD_RESOLUTION != 0 case.

      sched/fair: Optimize __update_load_avg()

      Prior to this patch; the line:

        scaled_delta_w = (delta_w * 1024) >> 10;

      which is the result of the default arch_scale_freq_capacity()
      function, turns into:

          1b03: 49 89 d1                mov    %rdx,%r9
          1b06: 49 c1 e1 0a             shl    $0xa,%r9
          1b0a: 49 c1 e9 0a             shr    $0xa,%r9

      Which is silly; when made unsigned int, GCC recognises this as
      pointless ops and fails to emit them (confirmed on 4.9.3 and 5.1.1).

      Furthermore, afaict unsigned is actually the correct type for these
      fields anyway, as we've explicitly ruled out negative delta's earlier
      in this function.

      Utilization is currently scaled by capacity_orig, but since we now have
      frequency and cpu invariant cfs_rq.avg.util_avg, frequency and cpu scaling
      now happens as part of the utilization tracking itself.
      So cfs_rq.avg.util_avg should no longer be scaled in cpu_util().

      sched/fair: Make utilization tracking CPU scale-invariant

      Besides the existing frequency scale-invariance correction factor, apply
      CPU scale-invariance correction factor to utilization tracking to
      compensate for any differences in compute capacity. This could be due to
      micro-architectural differences (i.e. instructions per seconds) between
      cpus in HMP systems (e.g. big.LITTLE), and/or differences in the current
      maximum frequency supported by individual cpus in SMP systems. In the
      existing implementation utilization isn't comparable between cpus as it
      is relative to the capacity of each individual CPU.

      Each segment of the sched_avg.util_sum geometric series is now scaled
      by the CPU performance factor too so the sched_avg.util_avg of each
      sched entity will be invariant from the particular CPU of the HMP/SMP
      system on which the sched entity is scheduled.

      With this patch, the utilization of a CPU stays relative to the max CPU
      performance of the fastest CPU in the system.

      In contrast to utilization (sched_avg.util_sum), load
      (sched_avg.load_sum) should not be scaled by compute capacity. The
      utilization metric is based on running time which only makes sense when
      cpus are _not_ fully utilized (utilization cannot go beyond 100% even if
      more tasks are added), where load is runnable time which isn't limited
      by the capacity of the CPU and therefore is a better metric for
      overloaded scenarios. If we run two nice-0 busy loops on two cpus with
      different compute capacity their load should be similar since their
      compute demands are the same. We have to assume that the compute demand
      of any task running on a fully utilized CPU (no spare cycles = 100%
      utilization) is high and the same no matter of the compute capacity of
      its current CPU, hence we shouldn't scale load by CPU capacity.

      sched/fair: Convert arch_scale_cpu_capacity() from weak function to 
#define

      Bring arch_scale_cpu_capacity() in line with the recent change of its
      arch_scale_freq_capacity() sibling in commit dfbca41f3479 ("sched:
      Optimize freq invariant accounting") from weak function to #define to
      allow inlining of the function.

      While at it, remove the ARCH_CAPACITY sched_feature as well. With the
      change to #define there isn't a straightforward way to allow runtime
      switch between an arch implementation and the default implementation of
      arch_scale_cpu_capacity() using sched_feature. The default was to use
      the arch-specific implementation, but only the arm architecture provides
      one and that is essentially equivalent to the default implementation.

      sched/fair: Make load tracking frequency scale-invariant

      Apply frequency scaling correction factor to per-entity load tracking to
      make it frequency invariant. Currently, load appears bigger when the CPU
      is running slower which affects load-balancing decisions.

      Each segment of the sched_avg.load_sum geometric series is now scaled by
      the current frequency so that the sched_avg.load_avg of each sched entity
      will be invariant from frequency scaling.

      Moreover, cfs_rq.runnable_load_sum is scaled by the current frequency as
      well.

      sched/numa: Disable sched_numa_balancing on UMA systems

      Commit 2a1ed24 ("sched/numa: Prefer NUMA hotness over cache hotness")
      sets sched feature NUMA to true. However this can enable NUMA hinting
      faults on a UMA system.

      This commit ensures that NUMA hinting faults occur only on a NUMA system
      by setting/resetting sched_numa_balancing.

      This commit:

        - Makes sched_numa_balancing common to CONFIG_SCHED_DEBUG and
          !CONFIG_SCHED_DEBUG. Earlier it was only in !CONFIG_SCHED_DEBUG.

        - Checks for sched_numa_balancing instead of sched_feat(NUMA).

      sched/fair: Fix nohz.next_balance update

      Since commit:

        d4573c3e1c99 ("sched: Improve load balancing in the presence of idle 
CPUs")

      the ILB CPU starts with the idle load balancing of other idle CPUs and
      finishes with itself in order to speed up the spread of tasks in all
      idle CPUs.

      The this_rq->next_balance is still used in nohz_idle_balance() as an
      intermediate step to gather the shortest next balance before updating
      nohz.next_balance. But the former has not been updated yet and is likely 
to
      be set with the current jiffies. As a result, the nohz.next_balance will 
be
      set with current jiffies instead of the real next balance date. This
      generates spurious kicks of nohz ilde balance.

      nohz_idle_balance() must set the nohz.next_balance without taking into
      account this_rq->next_balance which is not updated yet. Then, this_rq will
      update nohz.next_update with its next_balance once updated and if 
necessary.

      sched/fair: Unify switched_{from,to}_fair() and task_move_group_fair()

      By observing that switched_from_fair() detaches from a runqueue, and
      switched_to_fair() attaches to a runqueue, we can see that
      task_move_group_fair() is one followed by the other with flipping the
      runqueue in between.

      Therefore extract all the common bits and implement all three
      functions in terms of them.

      This should fix a few corner cases wrt. vruntime normalization; where,
      when we take a task off of a runqueue we convert to an approximation
      of lag by subtracting min_vruntime, and when placing a task on the a
      runqueue to the reverse.

      sched/fair: Fix switched_to_fair()'s per entity load tracking

      Where switched_from_fair() will remove the entity's load from the
      runqueue, switched_to_fair() does not currently add it back. This
      means that when a task leaves the fair class for a short duration; say
      because of PI; we loose its load contribution.

      This can ripple forward and disturb the load tracking because other
      operations (enqueue, dequeue) assume its factored in. Only once the
      runqueue empties will the load tracking recover.

      When we add it back in, age the per entity average to match up with
      the runqueue age. This has the obvious problem that if the task leaves
      the fair class for a significant time, the load will age to 0.

      Employ the normal migration rule for inter-runqueue moves in
      task_move_group_fair(). Again, there is the obvious problem of the
      task migrating while not in the fair class.

      The alternative solution would be to to omit the chunk in
      attach_entity_load_avg(), which would effectively reset the timestamp
      and use whatever avg there was.

      sched/fair: Have task_move_group_fair() also detach entity load from the 
old runqueue

      Since we attach the entity load to the new runqueue, we should also
      detatch the entity load from the old runqueue, otherwise load can
      accumulate.

      sched/fair: Have task_move_group_fair() unconditionally add the entity 
load to the runqueue

      Currently we conditionally add the entity load to the rq when moving
      the task between cgroups.

      This doesn't make sense as we always 'migrate' the task between
      cgroups, so we should always migrate the load too.

      [ The history here is that we used to only migrate the blocked load
        which was only meaningfull when !queued. ]

      x86/platform/uv: Insert per_cpu accessor function on uv_hub_nmi

      UV: NMI: insert this_cpu_read accessor function on uv_hub_nmi.

      On SGI UV systems a 'power nmi' command from the CMC causes
      all processors to drop into uv_handle_nmi().  With the 4.0
      kernel this results in

          BUG: unable to handle kernel paging request

      bridge: fix igmpv3 / mldv2 report parsing

      With the newly introduced helper functions the skb pulling is hidden in
      the checksumming function - and undone before returning to the caller.

      The IGMPv3 and MLDv2 report parsing functions in the bridge still
      assumed that the skb is pointing to the beginning of the IGMP/MLD
      message while it is now kept at the beginning of the IPv4/6 header,
      breaking the message parsing and creating packet loss.

      Fixing this by taking the offset between IP and IGMP/MLD header into
      account, too.

      bnx2x: use ktime_get_seconds() for timestamp

      commit c48f350ff5e7 "bnx2x: Add MFW dump support" added the
      bnx2x_update_mfw_dump() function that reads the current time and stores
      it in a 32-bit field that gets passed into a buffer in a fixed format.

      This is potentially broken when the epoch overflows in 2038, and
      otherwise overflows in 2106. As we're trying to avoid uses of
      struct timeval for this reason, I noticed the addition of this
      function, and tried to rewrite it in a way that is more explicit
      about the overflow and that will keep working once we deprecate
      struct timeval.

      I assume that it is not possible to change the ABI any more, otherwise
      we should try to use a 64-bit field for the seconds right away.

      sctp: fix race on protocol/netns initialization

      Consider sctp module is unloaded and is being requested because an user
      is creating a sctp socket.

      During initialization, sctp will add the new protocol type and then
      initialize pernet subsys:

              status = sctp_v4_protosw_init();
              if (status)
                      goto err_protosw_init;

              status = sctp_v6_protosw_init();
              if (status)
                      goto err_v6_protosw_init;

              status = register_pernet_subsys(&sctp_net_ops);

      The problem is that after those calls to sctp_v{4,6}_protosw_init(), it
      is possible for userspace to create SCTP sockets like if the module is
      already fully loaded. If that happens, one of the possible effects is
      that we will have readers for net->sctp.local_addr_list list earlier
      than expected and sctp_net_init() does not take precautions while
      dealing with that list, leading to a potential panic but not limited to
      that, as sctp_sock_init() will copy a bunch of blank/partially
      initialized values from net->sctp.

      The race happens like this:

           CPU 0                           |  CPU 1
        socket()                           |

           list_for_each_entry_rcu(        |
              answer, &inetsw[sock->type], |
              list) {                      |   inet_create
            /* no hits */                  |
           if (unlikely(err)) {            |
            ...                            |

            /* socket creation is blocked  |

              sctp_v6_protosw_init         |     list) {
                                           |     /* hit, so assumes protocol
                                           |      * is already loaded
                                           |      */
                                           |  /* socket creation continues
                                           |   * before netns is initialized

              register_pernet_subsys       |

      Simply inverting the initialization order between
      register_pernet_subsys() and sctp_v4_protosw_init() is not possible
      because register_pernet_subsys() will create a control sctp socket, so
      the protocol must be already visible by then. Deferring the socket
      creation to a work-queue is not good specially because we loose the
      ability to handle its errors.

      So, as suggested by Vlad, the fix is to split netns initialization in
      two moments: defaults and control socket, so that the defaults are
      already loaded by when we register the protocol, while control socket
      initialization is kept at the same moment it is today.

      ebpf: emit correct src_reg for conditional jumps

      Instead of always emitting BPF_REG_X, let's emit BPF_REG_X only when the
      source actually is BPF_X. This causes programs generated by the classic
      converter to not be importable via bpf(), as the eBPF verifier checks that
      the src_reg is correct or 0. While not a problem yet, this will be a
      problem when BPF_PROG_DUMP lands, and we can potentially dump and 
re-import
      programs generated by the converter.

      netlink, mmap: transform mmap skb into full skb on taps

      Ken-ichirou reported that running netlink in mmap mode for receive in
      combination with nlmon will throw a NULL pointer dereference in
      __kfree_skb() on nlmon_xmit(), in my case I can also trigger an "unable
      to handle kernel paging request". The problem is the skb_clone() in
      __netlink_deliver_tap_skb() for skbs that are mmaped.

      I.e. the cloned skb doesn't have a destructor, whereas the mmap netlink
      skb has it pointed to netlink_skb_destructor(), set in the handler
      netlink_ring_setup_skb(). There, skb->head is being set to NULL, so
      that in such cases, __kfree_skb() doesn't perform a skb_release_data()
      via skb_release_all(), where skb->head is possibly being freed through
      kfree(head) into slab allocator, although netlink mmap skb->head points
      to the mmap buffer. Similarly, the same has to be done also for large
      netlink skbs where the data area is vmalloced. Therefore, as discussed,
      make a copy for these rather rare cases for now. This fixes the issue
      on my and Ken-ichirou's test-cases.

      ARM: 8431/1: fix alignement of __bug_table section entries

      On old ARM chips, unaligned accesses to memory are not trapped and
      fixed.  On module load, symbols are relocated, and the relocation of
      __bug_table symbols is done on a u32 basis. Yet the section is not
      aligned to a multiple of 4 address, but to a multiple of 2.

      This triggers an Oops on pxa architecture, where address 0xbf0021ea
      is the first relocation in the __bug_table section :

      arm/xen: Enable user access to the kernel before issuing a privcmd call

      When Xen is copying data to/from the guest it will check if the kernel
      has the right to do the access. If not, the hypercall will return an
      error.

      After the commit a5e090acbf545c0a3b04080f8a488b17ec41fe02 "ARM:
      software-based privileged-no-access support", the kernel can't access
      any longer the user space by default. This will result to fail on every
      hypercall made by the userspace (i.e via privcmd).

      We have to enable the userspace access and then restore the correct
      permission every time the privcmd is used to made an hypercall.

      I didn't find generic helpers to do a these operations, so the change
      is only arm32 specific.

      ARM: domains: add memory dependencies to get_domain/set_domain

      We need to have memory dependencies on get_domain/set_domain to avoid
      the compiler over-optimising these inline assembly instructions.

      Loads/stores must not be reordered across a set_domain(), so introduce
      a compiler barrier for that assembly.

      The value of get_domain() must not be cached across a set_domain(), but
      we still want to allow the compiler to optimise it away.  Introduce a
      dependency on current_thread_info()->cpu_domain to avoid this; the new
      memory clobber in set_domain() should therefore cause the compiler to
      re-load this.  The other advantage of using this is we should have its
      address in the register set already, or very soon after at most call
      sites.

      block: blkg_destroy_all() should clear q->root_blkg and ->root_rl.blkg

      While making the root blkg unconditional, ec13b1d6f0a0 ("blkcg: always
      create the blkcg_gq for the root blkcg") removed the part which clears
      q->root_blkg and ->root_rl.blkg during q exit.  This leaves the two
      pointers dangling after blkg_destroy_all().  blk-throttle exit path
      performs blkg traversals and dereferences ->root_blkg and can lead to
      the following oops.

      While the bug is a straigh-forward use-after-free bug, it is tricky to
      reproduce because blkg release is RCU protected and the rest of exit
      path usually finishes before RCU grace period.

      This patch fixes the bug by updating blkg_destro_all() to clear
      q->root_blkg and ->root_rl.blkg.

      CIFS: fix type confusion in copy offload ioctl

      This might lead to local privilege escalation (code execution as
      kernel) for systems where the following conditions are met:

       - CONFIG_CIFS_SMB2 and CONFIG_CIFS_POSIX are enabled
       - a cifs filesystem is mounted where:
        - the mount option "vers" was used and set to a value >=2.0
        - the attacker has write access to at least one file on the filesystem

      To attack this, an attacker would have to guess the target_tcon
      pointer (but guessing wrong doesn't cause a crash, it just returns an
      error code) and win a narrow race.

      As Peterz pointed out:

      | So the normal rules for changing task_struct::cpus_allowed are holding
      | both pi_lock and rq->lock, such that holding either stabilizes the mask.
      |
      | This is so that wakeup can happen without rq->lock and load-balance
      | without pi_lock.
      |
      | From this we already get the relaxation that we can omit acquiring
      | rq->lock if the task is not on the rq, because in that case
      | load-balancing will not apply to it.
      |
      | ** these are the rules currently tested in do_set_cpus_allowed() **
      |
      | Now, since __set_cpus_allowed_ptr() uses task_rq_lock() which
      | unconditionally acquires both locks, we could get away with holding just
      | rq->lock when on_rq for modification because that'd still exclude
      | __set_cpus_allowed_ptr(), it would also work against
      | __kthread_bind_mask() because that assumes !on_rq.
      |
      | That said, this is all somewhat fragile.
      |
      | Now, I don't think dropping rq->lock is quite as disastrous as it
      | usually is because !cpu_active at this point, which means load-balance
      | will not interfere, but that too is somewhat fragile.
      |
      | So we end up with a choice of two fragile..

      This patch fixes it by following the rules for changing
      task_struct::cpus_allowed with both pi_lock and rq->lock held.

      locking/qspinlock/x86: Fix performance regression under unaccelerated VMs

      Dave ran into horrible performance on a VM without PARAVIRT_SPINLOCKS
      set and Linus noted that the test-and-set implementation was retarded.

      One should spin on the variable with a load, not a RMW.

      While there, remove 'queued' from the name, as the lock isn't queued
      at all, but a simple test-and-set.

      toshiba_acpi: Fix hotkeys registration on some toshiba models

      Commit a2b3471b5b13 ("toshiba_acpi: Use the Hotkey Event Type function
      for keymap choosing") changed the *setup_keyboard function to query for
      the Hotkey Event Type to help choose the correct keymap, but turns out
      that here are certain Toshiba models out there not implementing this
      feature, and thus, failing to continue the input device registration and
      leaving such laptops without hotkey support.

      This patch changes such check, and instead of returning an error if
      the Hotkey Event Type is not present, we simply inform userspace about it,
      changing the message printed from err to notice, making the function
      responsible for registering the input device to continue.

      This issue was found on a Toshiba Portege Z30-B, but there might be
      some other models out there affected by this regression as well.

      Now that the rockchip clock subsystem does clock gating with GPIO banks,
      these are no longer enabled once during probe and no longer stay enabled
      for eternity. When all these clocks are disabled, the parent clock 
pclk_peri
      might be disabled too, as no other child claims it. So, we need to add 
pclk_peri

      Currently the registration of critical clocks is done in the function
      shared between rk3066 and rk3188 clock trees. That results in them
      getting handled maybe before all of them are registered.

      Therefore move the critical clock handling down to the end of the soc-
      specific clock registration function, so that all clocks are registered
      before they're maybe handled as critical clock.

      string: provide strscpy()

      The strscpy() API is intended to be used instead of strlcpy(),
      and instead of most uses of strncpy().

      - Unlike strlcpy(), it doesn't read from memory beyond (src + size).

      - Unlike strlcpy() or strncpy(), the API provides an easy way to check
        for destination buffer overflow: an -E2BIG error return value.

      - The provided implementation is robust in the face of the source
        buffer being asynchronously changed during the copy, unlike the
        current implementation of strlcpy().

      - Unlike strncpy(), the destination buffer will be NUL-terminated
        if the string in the source buffer is too long.

      - Also unlike strncpy(), the destination buffer will not be updated
        beyond the NUL termination, avoiding strncpy's behavior of zeroing
        the entire tail end of the destination buffer.  (A memset() after
        the strscpy() can be used if this behavior is desired.)

      - The implementation should be reasonably performant on all
        platforms since it uses the asm/word-at-a-time.h API rather than
        simple byte copy.  Kernel-to-kernel string copy is not considered
        to be performance critical in any case.

      wmi: Remove private %pUL implementation

      The work performed by wmi_gtoa is equivalent to simply sprintf(out,
      "%pUL", in), so one could replace its body by this. However, most
      users feed the result directly as a %s argument to some other function
      which also understands the %p extensions (they all ultimately use
      vsnprintf), so we can eliminate some stack buffers and quite a bit of
      code by just using %pUL directly.

      In wmi_dev_uevent I'm not sure whether there's room for a
      nul-terminator in env->buf, so I've just replaced wmi_gtoa with the
      equivalent sprintf call.

      Btrfs: remove unnecessary locking of cleaner_mutex to avoid deadlock

      After commmit e44163e17796 ("btrfs: explictly delete unused block groups
      in close_ctree and ro-remount"), added in the 4.3 merge window, we have
      calls to btrfs_delete_unused_bgs() while holding the cleaner_mutex.
      This can cause a deadlock with a concurrent block group relocation (when
      a filesystem balance or shrink operation is in progress for example)
      because btrfs_delete_unused_bgs() locks delete_unused_bgs_mutex and the
      relocation path locks first delete_unused_bgs_mutex and then it locks
      cleaner_mutex, resulting in a classic ABBA deadlock:

               CPU 0                                        CPU 1

      lock fs_info->cleaner_mutex

                                                 __btrfs_balance() || 
btrfs_shrink_device()

      Fix this by not taking the cleaner_mutex before calling
      btrfs_delete_unused_bgs() because it's no longer needed after
      commit 67c5e7d464bc ("Btrfs: fix race between balance and unused block
      group deletion"). The mutex fs_info->delete_unused_bgs_mutex, the
      spinlock fs_info->unused_bgs_lock and a block group's spinlock are
      enough to get correct serialization between tasks running relocation
      and unused block group deletion (as well as between multiple tasks
      concurrently calling btrfs_delete_unused_bgs()).

      This issue was discussed (in the mailing list) during the review of
      the patch titled "btrfs: explictly delete unused block groups in
      close_ctree and ro-remount" and it was agreed that acquiring the
      cleaner mutex had to be dropped after the patch titled
      "Btrfs: fix race between balance and unused block group deletion"
      got merged (both patches were submitted at about the same time, but
      one landed in kernel 4.2 and the other in the 4.3 merge window).

      spi: bcm2835: BUG: fix wrong use of PAGE_MASK

      There is a bug in the alignment checking of transfers,
      that results in DMA not being used for un-aligned
      transfers that do not cross page-boundries, which is valid.

      This is due to a missconception of the meaning PAGE_MASK

      should have been used instead.

      powerpc/MSI: Fix race condition in tearing down MSI interrupts

      This fixes a race which can result in the same virtual IRQ number
      being assigned to two different MSI interrupts.  The most visible
      consequence of that is usually a warning and stack trace from the
      sysfs code about an attempt to create a duplicate entry in sysfs.

      The race happens when one CPU (say CPU 0) is disposing of an MSI
      while another CPU (say CPU 1) is setting up an MSI.  CPU 0 calls
      (for example) pnv_teardown_msi_irqs(), which calls
      msi_bitmap_free_hwirqs() to indicate that the MSI (i.e. its
      hardware IRQ number) is no longer in use.  Then, before CPU 0 gets
      to calling irq_dispose_mapping() to free up the virtal IRQ number,
      CPU 1 comes in and calls msi_bitmap_alloc_hwirqs() to allocate an
      MSI, and gets the same hardware IRQ number that CPU 0 just freed.
      CPU 1 then calls irq_create_mapping() to get a virtual IRQ number,
      which sees that there is currently a mapping for that hardware IRQ
      number and returns the corresponding virtual IRQ number (which is
      the same virtual IRQ number that CPU 0 was using).  CPU 0 then
      calls irq_dispose_mapping() and frees that virtual IRQ number.
      Now, if another CPU comes along and calls irq_create_mapping(), it
      is likely to get the virtual IRQ number that was just freed,
      resulting in the same virtual IRQ number apparently being used for
      two different hardware interrupts.

      To fix this race, we just move the call to msi_bitmap_free_hwirqs()
      to after the call to irq_dispose_mapping().  Since virq_to_hw()
      doesn't work for the virtual IRQ number after irq_dispose_mapping()
      has been called, we need to call it before irq_dispose_mapping() and
      remember the result for the msi_bitmap_free_hwirqs() call.

      The pattern of calling msi_bitmap_free_hwirqs() before
      irq_dispose_mapping() appears in 5 places under arch/powerpc, and
      appears to have originated in commit 05af7bd2d75e ("[POWERPC] MPIC
      U3/U4 MSI backend") from 2007.

      ath10k: fix DMA alloc failure for target requested memory chunks

      During long hours of stress testing like AP interface up/down along
      with continuous ping flood from a station doing connect/disconnect,
      it is observed that the system is not able to allocate DMA consistent
      memory of size > 512KB chunks as requested by firmware in 
WMI_SERVICE_EVENTID.
      With the system memory getting fragmented during the run based on the
      size of the memory requested, the failure to return physically continguous
      memory of high order can happen. Once the system gets to this situation,
      bringing up the wifi interface will fail and a system reboot may be needed
      to make it work again. This problem is obseved with QCA99X0.

      To fix this issue, allocate the DMA memory requested by firmware during
      device probe time and keep it during the life time of the device. WMI 
service
      ready event handler is changed to allocate the memory chunks if it is
      not already allocated or if the memory allocated for the previous ready
      event is not same as the current requested ones. After this patch the
      memory usage when wifi is inactive will be inceased by few 100KB to
      3MB based on the target type.

      MU-MIMO Rx involves different interpretation of

      The incorrect interpretation led ath10k to report

      prompted mac80211 to drop such frames. This
      effectively broke Rx with MU-MIMO in many cases
      and manifested with a kernel warning in the log
      which looked like this:

      Merge tag 'perf-core-for-mingo' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      User visible changes:

        - Use PERF_RECORD_SWITCH when available in intel-pt, instead of
          "sched:sched_switch" events, enabling an unprivileged user to trace
          multi-threaded or multi-process workloads. (Adrian Hunter)

        - Always use non inlined file name for 'srcfile' sort key. (Andi Kleen)

        - Quieten failed to read counter message, helps in systems without
          backend-stalled-cycles. (Andi Kleen)

      Infrastructure changes:

        - Add a 'perf test' entry for decoding of new x86 instructions. (Adrian 
Hunter)

        - Add new instructions (sha, clflushopt, clwb, pcommit, rdpkru, wrpkru, 
xsavec,
          xsaves, xrstors) to the x86 instruction decoder. (Adrian Hunter)

        - Add a build test to warn when source code drifts happen for the
          instruction decoder files in the kernel and in tools/perf. (Adrian 
Hunter)

        - Copy linux/filter.h to tools/include. (He Kuang)

        - Support function __get_dynamic_array_len in libtraceevent. (He 
Kuanguuu)

        - Tracing path finding/mounting/error reporting refactorings. (Jiri 
Olsa)

        - Store CPU socket and core IDs in perf.data. (Kan Liang)

        - Reorganize add/del probe insertion routines in 'perf probe'.

      Now that all type definitions are in the UAPI header, include it

      Now that all sigcontext types are defined in asm/sigcontext.h,
      remove the various sigcontext32.h uses in the kernel.

      We still keep the header itself, which includes sigcontext.h, in

      x86/headers: Move the 'struct sigcontext' definitions into the UAPI header

      Our goal is to eliminate the duplicate struct sigcontext_ia32
      definition, so move the kernel's primary sigcontext type into
      the UAPI header, defining these two variants:

        struct sigcontext_32
        struct sigcontext_64

      ... and map them to 'struct sigcontext'.

      x86/headers: Unify 'struct _fpstate_ia32' and i386 struct _fpstate

      'struct _fpstate_ia32' and 'struct _fpstate' on i386 are
      identical in all fields, except 'padding1' being named
      'padding'.

      We unify the two structures and add a union that is both named
      'padding1' and 'padding', in the (unlikely) case there's
      user-space code that relies on the padding field name.

      We rename the two main types to be:

        struct _fpstate_32
        struct _fpstate_64

      for the 32-bit and 64-bit frame, and map them to the main and
      compat structure names (_fpstate) depending on whether we are on
      32-bit or on 64-bit kernels.

      We also keep the old _fpstate_ia32 name as a legacy name.

      x86/headers: Fix (old) header file dependency bug in 
uapi/asm/sigcontext32.h

      Mikko Rapeli reported that the following standalone user-space
      header does not compile:

        #include <asm/sigcontext32.h>

      Due to undefined 'struct __fpx_sw_bytes' which is defined in
      asm/sigcontext.h.

      The following header order works:

        #include <asm/sigcontext.h>
        #include <asm/sigcontext32.h>

      and that's probably how everyone's been using these headers for
      the past decade or so, but it's a legit header file dependency
      bug, so include asm/sigcontext.h in sigcontext32.h to allow it
      to be built standlone.

      powerpc/pseries: Release DRC when configure_connector fails

      Commit f32393c943e2 ("powerpc/pseries: Correct cpu affinity for
      dlpar added cpus") moved dlpar_acquire_drc() call to before
      dlpar_configure_connector() call in dlpar_cpu_probe(), but missed
      to release the DRC if dlpar_configure_connector() failed.
      During CPU hotplug, if configure-connector fails for any reason,
      then this will result in subsequent CPU hotplug attempts to fail.

      Release the acquired DRC if dlpar_configure_connector() call fails
      so that the DRC is left in right isolation and allocation state
      for the subsequent hotplug operation to succeed.

      Btrfs: don't initialize a space info as full to prevent ENOSPC

      Commit 2e6e518335f8 ("Btrfs: fix block group ->space_info null pointer
      dereference") accidently marked a space info as full when initializing
      it with a value of 0 total bytes. This introduces an ENOSPC problem when
      writing file data if we mount a filesystem that has no data block groups
      allocated, because the data space info is initialized with 0 total bytes,
      marked as full, and it never gets its total bytes incremented by a
      (positive) value to unmark it as full (because there are no data block
      groups loaded when the fs is mounted).
      For metadata and system spaces this issue can never happen since we always
      have at least one metadata block group and one system block group (even
      for an empty filesystem).

      So fix this by just not initializing a space info as full, reverting the
      offending part of the commit mentioned above.

      The following test case for fstests reproduces the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"

      Instead, it supplies pause mode to do it indirectly. If driver

      ARM: 8429/1: disable GCC SRA optimization

      While working on the 32-bit ARM port of UEFI, I noticed a strange
      corruption in the kernel log. The following snprintf() statement
      (in drivers/firmware/efi/efi.c:efi_md_typeattr_format())

        snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]",

      was producing the following output in the log:

        |    |   |   |   |    |WB|WT|WC|UC]
        |    |   |   |   |    |WB|WT|WC|UC]
        |    |   |   |   |    |WB|WT|WC|UC]

        |RUN|   |   |   |    |WB|WT|WC|UC]*
        |    |   |   |   |    |WB|WT|WC|UC]
        |RUN|   |   |   |    |WB|WT|WC|UC]*
        |    |   |   |   |    |WB|WT|WC|UC]

        |RUN|   |   |   |    |   |   |   |UC]

      As it turns out, this is caused by incorrect code being emitted for
      the string() function in lib/vsprintf.c. The following code

        if (!(spec.flags & LEFT)) {
                while (len < spec.field_width--) {
                        if (buf < end)
                                *buf = ' ';
                        ++buf;
                }
        }
        for (i = 0; i < len; ++i) {
                if (buf < end)
                        *buf = *s;
                ++buf; ++s;
        }
        while (len < spec.field_width--) {
                if (buf < end)
                        *buf = ' ';
                ++buf;
        }

      when called with len == 0, triggers an issue in the GCC SRA optimization
      pass (Scalar Replacement of Aggregates), which handles promotion of signed
      struct members incorrectly. This is a known but as yet unresolved issue.
      (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular
      case, it is causing the second while loop to be executed erroneously a
      single time, causing the additional space characters to be printed.

      So disable the optimization by passing -fno-ipa-sra.

      sitting on a vPHB. At present, the state of the underlying CXL card's PCI

      very end, after it has already set DMA options and initialised a default
      context.

      Check the CXL card's link status before setting DMA options or

      powerpc/powernv/pci-ioda: fix kdump with non-power-of-2 crashkernel=

      The 32-bit TCE table initialization relies on the DMA window having a
      size equal to a power of 2 (and checks for it explicitly). But
      crashkernel= has no constraint that requires a power-of-2 be specified.
      This causes the kdump kernel to fail to boot as none of the PCI devices
      (including the disk controller) are successfully initialized.

      After this change, the PCI devices successfully set up the 32-bit TCE
      table and kdump succeeds.

      powerpc/powernv/pci-ioda: fix 32-bit TCE table init in kdump kernel

      When attempting to kdump with the 4.2 kernel, we see for each PCI
      device:

       pci 0003:01     : [PE# 000] Assign DMA32 space
       pci 0003:01     : [PE# 000] Setting up 32-bit TCE table at 0..80000000

       pci 0004:10     : [PE# 008] Failed to create 32-bit TCE table, err -22

      and eventually the kdump kernel fails to boot as none of the PCI devices
      (including the disk controller) are successfully initialized.

      The EINVAL response is because the DMA window (the 2GB base window) is
      larger than the kdump kernel's reserved memory (crashkernel=, in this
      case specified to be 1024M). The check in question,

       if ((window_size > memory_hotplug_max()) || !is_power_of_2(window_size))

      is a valid sanity check for pnv_pci_ioda2_table_alloc_pages(), so adjust
      the caller to pass in a smaller window size if our maximum memory value
      is smaller than the DMA window.

      After this change, the PCI devices successfully set up the 32-bit TCE
      table and kdump succeeds.

      The problem was seen on a Firestone machine originally.

      spi: Fix documentation of spi_alloc_master()

      Actually, spi_master_put() after spi_alloc_master() must _not_ be followed
      by kfree(). The memory is already freed with the call to spi_master_put()
      through spi_master_class, which registers a release function. Calling both
      spi_master_put() and kfree() results in often nasty (and delayed) crashes
      elsewhere in the kernel, often in the networking stack.

      This reverts commit eb4af0f5349235df2e4a5057a72fc8962d00308a.

      or

      Alexey Klimov: This revert becomes valid after
      94c69f765f1b4a658d96905ec59928e3e3e07e6a when spi-imx.c
      has been fixed and there is no need to call kfree() so comment
      for spi_alloc_master() should be fixed.

      x86/vm86: Block non-root vm86(old) if mmap_min_addr != 0

      vm86 exposes an interesting attack surface against the entry
      code. Since vm86 is mostly useless anyway if mmap_min_addr != 0,
      just turn it off in that case.

      There are some reports that vbetool can work despite setting
      mmap_min_addr to zero.  This shouldn't break that use case,
      as CAP_SYS_RAWIO already overrides mmap_min_addr.

      perf probe: Print deleted events in cmd_probe()

      Showing actual trace event when deleteing perf events is only needed in
      perf probe command.  But the add functionality itself can be used by
      other places.  So move the printing code into the cmd_probe().

      The output is not changed.

      perf probe: Split del_perf_probe_events()

      The del_perf_probe_events() does 2 things:

      1. find existing events which match to filter
      2. delete such trace events from kernel

      But sometimes we need to do something with the trace events.  So split
      the funtion into two, so that it can access intermediate trace events
      name using strlist if needed.

      Showing actual trace event when adding perf events is only needed in
      perf probe command.  But the add functionality itself can be used by
      other places.  So move the printing code into the cmd_probe().

      Also it combines the output if more than one event is added.

      Before:
        $ sudo perf probe -a do_fork -a do_exit
        Added new event:
        probe:do_fork        (on do_fork)

        You can now use it in all perf tools, such as:

            perf record -e probe:do_fork -aR sleep 1

        Added new events:
        probe:do_exit        (on do_exit)
        probe:do_exit_1      (on do_exit)

        You can now use it in all perf tools, such as:

      perf probe: Link trace_probe_event into perf_probe_event

      This patch drops struct __event_package structure.  Instead, it adds a
      'struct trace_probe_event' pointer to 'struct perf_probe_event'.

      The trace_probe_event information gives further patches a chance to
      access actual probe points and actual arguments.

      Using them, 'perf probe' can get the whole list of added probes and
      print them at once.

      Other users like the upcoming bpf_loader will be able to attach one bpf
      program to different probing points of an inline function (which has
      multiple probing points) and glob functions.

      Moreover, by reading the arguments information, bpf code for reading
      those arguments can be generated.

      arm/arm64: KVM: vgic: Move active state handling to flush_hwstate

      We currently set the physical active state only when we *inject* a new
      pending virtual interrupt, but this is actually not correct, because we
      could have been preempted and run something else on the system that
      resets the active state to clear.  This causes us to run the VM with the
      timer set to fire, but without setting the physical active state.

      The solution is to always check the LR configurations, and we if have a
      mapped interrupt in the LR in either the pending or active state
      (virtual), then set the physical active state.

      perf intel-pt: Add support for PERF_RECORD_SWITCH

      Add support for selecting and processing PERF_RECORD_SWITCH events for
      use by Intel PT.  If they are available, they will be used in preference
      to sched_switch events.

      This enables an unprivileged user to trace multi-threaded or
      multi-process workloads with any level of perf_event_paranoid.  However
      it depends on kernel support for PERF_RECORD_SWITCH.

      Without this patch, tracing a multi-threaded workload will decode
      without error but all the data will be attributed to the main thread.

      Without this patch, tracing a multi-process workload will result in
      decoder errors because the decoder will not know which executable is
      executing.

      x86/insn: perf tools: Pedantically tweak opcode map for MPX instructions

      The MPX instructions are presently not described in the SDM
      opcode maps, and there are not encoding characters for bnd
      registers, address method or operand type.  So the kernel
      opcode map is using 'Gv' for bnd registers and 'Ev' for
      everything else.  That is fine because the instruction
      decoder does not use that information anyway, except as
      an indication that there is a ModR/M byte.

      Nevertheless, in some cases the 'Gv' and 'Ev' are the wrong
      way around, BNDLDX and BNDSTX have 2 operands not 3, and it
      wouldn't hurt to identify the mandatory prefixes.

      This has no effect on the decoding of valid instructions,
      but the addition of the mandatory prefixes will cause some
      invalid instructions to error out that wouldn't have
      previously.

      Note that perf tools has a copy of the instruction decoder
      and provides a test for new instructions which includes MPX
      instructions e.g.

        $ perf test "x86 ins"
        39: Test x86 instruction decoder - new instructions          : Ok

      Or to see the details:

        $ perf test -v "x86 ins"

      Commiter notes:

      And to see these MPX instructions specifically:

        $ perf test -v "x86 ins" 2>&1 | grep bndldx | head -3
        Decoded ok: 0f 1a 00                    bndldx (%eax),%bnd0
        Decoded ok: 0f 1a 05 78 56 34 12        bndldx 0x12345678,%bnd0
        Decoded ok: 0f 1a 18                    bndldx (%eax),%bnd3

      perf tools: Add a test for decoding of new x86 instructions

      Add a new test titled:

        Test x86 instruction decoder - new instructions

      The purpose of this test is to check the instruction decoder after new
      instructions have been added.  Initially, MPX instructions are tested
      which are already supported, but the definitions in x86-opcode-map.txt
      will be tweaked in a subsequent patch, after which this test can be run
      to verify those changes.

      The data for the test comes from assembly language instructions in
      insn-x86-dat-src.c which is converted into bytes by the scripts
      gen-insn-x86-dat.sh and gen-insn-x86-dat.awk, and included into the test
      program insn-x86.c as insn-x86-dat-32.c and insn-x86-dat-64.c.

      The conversion is not done as part of the perf tools build because the
      test data must be under (git) change control in order for the test to be
      repeatably-correct.  Also it may require a recent version of binutils.

      perf tools: Display build warning if x86 instruction decoder differs from 
kernel

      perf tools has a copy of the x86 instruction decoder used by the kernel.
      The expectation is that the copy will be kept more-or-less in-synch with
      the kernel version.  Consequently it is helpful to know if there are
      differences.

      This patch adds a check into the perf tools build so that a diff is done
      on the sources, and a warning is printed if they are different.  Note
      that the warning is not fatal and the build continues as normal.

      The check is done as part of building the instruction decoder, so, like
      a compiler warning, it is not seen unless the instruction decoder has to
      be re-compiled. e.g.

        $ make -C tools/perf >/dev/null
        $ echo "/* blah */" >> tools/perf/util/intel-pt-decoder/inat_types.h
        $ make -C tools/perf >/dev/null
        Warning: Intel PT: x86 instruction decoder differs from kernel
        $ make -C tools/perf >/dev/null
        $

      Merge tag 'perf-urgent-for-mingo' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

      Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

        - In some cases where perf_event.fork.{pid,tid} should be used we were 
instead
          using perf_event.comm.{pid,tid}, which is not a problem for for the 
'pid'
          case, that sits in the same place in these union_perf_event members, 
but
          comm.tid sits where fork.ppid is, oops.

          These cases were considered as (potentially) problematic:

           - 'perf script' with !sample_id_all, i.e. only non old kernels 
without
              perf_event_attr.sample_id_all.

           - intel_pt could be affected when decoding without timestamps, as 
the exit
             event is only used to flush out data which anyway gets flushed at 
the
             end of the session.

           - intel_bts also uses the exit event to flush data which would 
probably not
             cause errors as it would get flushed at the end of the session 
instead.

          Fix it. (Adrian Hunter)

        - Due to relaxing the compiler checks for bison generated files, we 
missed
          updating one parse_events_add_pmu() caller when this function had its
          prototype changed, fix it. (Jiri Olsa)

      ipv6: Fix IPsec pre-encap fragmentation check

      The IPv6 IPsec pre-encap path performs fragmentation for tunnel-mode
      packets.  That is, we perform fragmentation pre-encap rather than
      post-encap.

      A check was added later to ensure that proper MTU information is
      passed back for locally generated traffic.  Unfortunately this
      check was performed on all IPsec packets, including transport-mode
      packets.

      What's more, the check failed to take GSO into account.

      The end result is that transport-mode GSO packets get dropped at
      the check.

      This patch fixes it by moving the tunnel mode check forward as well
      as adding the GSO check.

      optimize_nops() is buggy in two aspects:

      The previous code, kernel builds Hi6220's common clock driver and stub
      clock driver together. Stub clock driver has introduced the dependency
      with CONFIG_MAILBOX, so kernel will not build Hi6220's common clock
      driver due ARM64's defconfig have not enabled CONFIG_MAILBOX by default.

      So separately build stub clock driver and common clock driver for
      Hi6220; and only let stub clock driver has the dependency with

      block: Check for gaps on front and back merges

      We are checking for gaps to previous bio_vec, which can
      only detect back merges gaps. Moreover, at the point where
      we check for a gap, we don't know if we will attempt a back
      or a front merge. Thus, check for gap to prev in a back merge
      attempt and check for a gap to next in a front merge attempt.

      This helps avoid depending on the dt for pbias register offset.

      null_blk: fix wrong capacity when bs is not 512 bytes

      set_capacity() sets device's capacity using 512 bytes sectors.
      null_blk calculates the number of sectors by size / bs, which
      set_capacity is called with. This led to null_blk exposing the

      perf tools: Fix use of wrong event when processing exit events

      In a couple of cases the 'comm' member of 'union event' has been used
      instead of the correct member ('fork') when processing exit events.

      In the cases where it has been used incorrectly, only the 'pid' and
      'tid' are affected.  The 'pid' value would be correct anyway because it
      is in the same position in 'comm' and 'fork' events, but the 'tid' would
      have been incorrectly assigned from 'ppid'.

      However, for exit events, the kernel puts the current task in the 'ppid'
      and 'ttid' which is the same as the exiting task.  That is 'ppid' ==
      'pid' and if the task is not multi-threaded, 'pid' == 'tid' i.e. the
      data goes wrong only when tracing multi-threaded programs.

      It is hard to find an example of how this would produce an error in
      practice.  There are 3 occurences of the fix:

      1. perf script is only affected if !sample_id_all which only happens on
        old kernels.

      2. intel_pt is only affected when decoding without timestamps
         and would probably still decode correctly - the exit event is
         only used to flush out data which anyway gets flushed at the
         end of the session

      3. intel_bts also uses the exit event to flush data which
         would probably not cause errors as it would get flushed at
         the end of the session instead

      perf tools: Store the cpu socket and core ids in the perf.data header

      This patch stores the cpu socket_id and core_id in a perf.data header,
      and reads them into the perf_env struct when processing perf.data files.

      The changes modifies the CPU_TOPOLOGY section, making sure it is
      backward/forward compatible.

      The patch checks the section size before reading the core and socket ids.

      It never reads data crossing the section boundary.  An old perf binary
      without this patch can also correctly read the perf.data from a new perf
      with this patch.

      Because the new info is added at the end of the cpu_topology section, an
      old perf tool ignores the extra data.

      Examples:

      1. New perf with this patch read perf.data from an old perf without the
         patch:

        $ perf_new report -i perf_old.data --header-only -I
        ......
        # sibling threads : 33
        # sibling threads : 34
        # sibling threads : 35
        # Core ID and Socket ID information is not available
        # node0 meminfo  : total = 32823872 kB, free = 29315548 kB
        # node0 cpu list : 0-17,36-53
        ......

      2. Old perf without the patch reads perf.data from a new perf with the
         patch:

        $ perf_old report -i perf_new.data --header-only -I
        ......
        # sibling threads : 33
        # sibling threads : 34
        # sibling threads : 35
        # node0 meminfo  : total = 32823872 kB, free = 29190932 kB
        # node0 cpu list : 0-17,36-53
        ......

      3. New perf read new perf.data:

        $ perf_new report -i perf_new.data --header-only -I
        ......
        # sibling threads : 33
        # sibling threads : 34
        # sibling threads : 35
        # CPU 0: Core ID 0, Socket ID 0
        # CPU 1: Core ID 1, Socket ID 0
        ......
        # CPU 61: Core ID 10, Socket ID 1
        # CPU 62: Core ID 11, Socket ID 1
        # CPU 63: Core ID 16, Socket ID 1
        # node0 meminfo  : total = 32823872 kB, free = 29190932 kB

      This patch copies filter.h from include/linux/kernel.h to

it,
      like libbpf which will be introduced by further patches.

      Currently, the filter.h copy only contains the useful macros needed by
      libbpf for not introducing too much dependence.

      tools/perf/MANIFEST is also updated for 'make perf-*-src-pkg'.

      One change:
        The 'imm' field of BPF_EMIT_CALL becomes ((FUNC) - BPF_FUNC_unspec) to
        suit user space code generator.

      perf tools: Always use non inlined file name for 'srcfile' sort key

      When profiling the kernel with the 'srcfile' sort key it's common to
      "get stuck" in include. For example a lot of code uses current or other
      inlines, so they get accounted to some random include file. This is not
      very useful as a high level categorization.

      For example just profiling the idle loop usually shows mostly inlines,
      so you never see the actual cpuidle file.

      This patch changes the 'srcfile' sort key to always unwind the inline
      stack using BFD/DWARF. So we always account to the base function that
      called the inline.

      In a few cases include is still shown (for example for MSR accesses),
      but that is because they get inlining expanded as part of assigning to a
      global function pointer. For the majority it works fine though.

      v2: Use simpler while loop. Add maximum iteration count.

      spi: spi-pxa2xx: Check status register to determine if SSSR_TINT is

      On Intel Baytrail, there is case when interrupt handler get called, no SPI

      interrupt (SSSR_TINT) happens.

      Use the BIOS version where both HSUART and SPI are on the same IRQ. Both
      drivers are using IRQF_SHARED when calling the request_irq function. When
      running two separate and independent SPI and HSUART application that
      generate data traffic on both components, user will see messages like
      below on the console:

      This commit will fix this by first checking Receiver Time-out Interrupt,
      if it is disabled, ignore the request and return without servicing.

      CPUs run undisturbed.

      Also improve the comments on housekeeper offlining prevention.

      nohz: Affine unpinned timers to housekeepers

      The problem addressed in this patch is about affining unpinned
      timers. Adaptive or Full Dynticks CPUs are currently disturbed
      by unnecessary jitter due to firing of such timers on them.

      This patch will affine timers to online CPUs which are not full
      dynticks in NOHZ_FULL configured systems. It should not
      introduce overhead in nohz full off case due to static keys.

      x86/mm/srat: Print non-volatile flag in SRAT

      With the addition of NVDIMM support, a question came up as to
      whether NVDIMM ranges should be in the SRAT with this bit set.
      I think the consensus was no because the ranges are in the NFIT
      with proximity domain information there.

      ACPI is not clear on the meaning of this bit in the SRAT.
      If someone is setting it, we might want to ask them what they
      expect to happen with it.

      Right now this bit is only printed if all the ACPI debug
      information is turned on.

      ARM: DRA752: Add ID detect for ES2.0

      ES2.0 is a minor variant of ES1.1. ES2.0 is an incremental revision
      with various fixes including the following:
        - reset logic fixes
        - few assymetric aging logic fixes
        - MMC clock rate fixes
        - Ethernet speed fixes
        - edma fixes for mcasp

      NOTE: even though we use a compatible of dra742 and dra752, the usage in
      the Linux kernel is more or less interchangable - we use dra752 more
      often in the linux kernel compared to dra742 and 4.2-rc6

      ARM: OMAP2+: Fix booting if no timer parent clock is available

      When bringing up a new SoC we needlessly prevent booting at timer
      init if timer clock_set_parent fails. This can fail if the system
      is booting on bootloader configured PLL values until the clock
      framework driver for the PLL is implemented.

      Let's just WARN instead, this will provide helpful information
      for anybody bringing up a new SoC what needs to be fixed.

      This allows to boot dm814x that's still missing the PLL driver.

      ARM: OMAP2+: omap-device: fix race deferred probe of omap_hsmmc vs 
omap_device_late_init

      Kernel fails to boot 50% of times (form build to build) with
      RT-patchset applied due to the following race - on late boot
      stages deferred_probe_work_func->omap_hsmmc_probe races with 
omap_device_late_ini.

      The same issue has been reported now on linux-next (4.3) by Keerthy [1]

      late_initcall
       - deferred_probe_initcal() tries to re-probe all pending driver's probe.

      - later on, some driver is probing in this case It's cpsw.c
        (but could be any other drivers)
        cpsw_init
        - platform_driver_register
          - really_probe
             - driver_bound
               - driver_deferred_probe_trigger
        and boot proceed.
        So, at this moment we have deferred_probe_work_func scheduled.

      late_initcall_sync
        - omap_device_late_init
          - omap_device_idle

      The issue happens because omap_device_late_init() do not take into
      account that some drivers are present, but their probes were not
      finished successfully and where deferred instead. This is the valid
      case, and omap_device_late_init() should not idle such devices.

      To fix this issue, the value of omap_device->_driver_status field
      should be checked not only for BUS_NOTIFY_BOUND_DRIVER (driver is
      present and has been bound to device successfully), but also checked
      for BUS_NOTIFY_BIND_DRIVER (driver about to be bound) - which means
      driver is present and there was try to bind it to device.

      iwlwifi: mvm: make sure d0i3 exit work runs before suspending

      If we are in d0i3 when entering suspend, we leave d0i3 so that
      mac80211 can call us to remove connections or whatever before going to
      suspend.  We do this by calling pm_runtime_resume() early in the slave
      transport flow and reactivating it later, when the wiphy suspend flow
      runs.

      The problem is that we queue a work in order to leave d0i3.  If this
      work hasn't run yet when the wiphy suspend flow is called, we have a
      race and entering d0i3 fails (because we're still holding the
      IWL_MVM_REF_EXIT_WORK reference).

      To solve this, simply flush the d0i3_exit_work at the beginning of the
      iwl_mvm_suspend() function.

      When in AP mode, we need beacons from other APs for HT protection.
      However, when there's no any associated station we will not do
      any Tx and thus don't really need beacons. On the other hand, these
      beacons will cause a lot of unnecessary wakeups which increase our
      power consumption. Handle this by asking FW to pass beacons only when

      Laura Abbott <labbott@xxxxxxxxxx> produced a patch which lead us to
      inspect symbol_put_addr(). This function has a comment claiming it
      doesn't need to disable preemption around the module lookup
      because it holds a reference to the module it wants to find, which
      therefore cannot go away.

      This is wrong (and a false optimization too, preempt_disable() is really
      rather cheap, and I doubt any of this is on uber critical paths,
      otherwise it would've retained a pointer to the actual module anyway and
      avoided the second lookup).

      While its true that the module cannot go away while we hold a reference
      on it, the data structure we do the lookup in very much _CAN_ change
      while we do the lookup. Therefore fix the comment and add the
      required preempt_disable().

      Each of those EFI memory types is mapped to a corresponding

      and PROT_NORMWL_WT additionaly.

      MT_NORMAL_WT is defined, and its encoding is added to MAIR_EL1

      acpi, x86: Implement arch_apei_get_mem_attributes()

      ... to allow an arch specific implementation of getting page
      protection type associated with a physical address.

      On x86, we currently have no way to look up the EFI memory map
      attributes for a region in a consistent way, because the
      memmap is discarded after efi_free_boot_services(). So if
      you call efi_mem_attributes() during boot and at runtime,
      you could theoretically see different attributes.

      Since we are yet to see any x86 platforms that require
      anything other than PAGE_KERNEL (some arm64 platforms
      require the equivalent of PAGE_KERNEL_NOCACHE), return that

      efi, x86: Rearrange efi_mem_attributes()

      x86 and ia64 implement efi_mem_attributes() differently. This
      function needs to be available for other architectures
      (such as arm64) as well, such as for the purpose of ACPI/APEI.

      ia64 EFI does not set up a 'memmap' variable and does not set
      the EFI_MEMMAP flag, so it needs to have its unique implementation
      of efi_mem_attributes().

      Move efi_mem_attributes() implementation from x86 to the core
      EFI code, and declare it with __weak.

      It is recommended that other architectures should not override
      the default implementation.

      Revert "x86/efi: Request desired alignment via the PE/COFF headers"

      This reverts commit:

        aeffc4928ea2 ("x86/efi: Request desired alignment via the PE/COFF 
headers")

      Linn reports that Signtool complains that kernels built with
      CONFIG_EFI_STUB=y are violating the PE/COFF specification because
      the 'SizeOfImage' field is not a multiple of 'SectionAlignment'.

      This violation was introduced as an optimisation to skip having
      the kernel relocate itself during boot and instead have the
      firmware place it at a correctly aligned address.

      No one else has complained and I'm not aware of any firmware
      implementations that refuse to boot with commit aeffc4928ea2,
      but it's a real bug, so revert the offending commit.

      x86/efi-bgrt: Switch pr_err() to pr_debug() for invalid BGRT

      It's totally legitimate, per the ACPI spec, for the firmware to
      set the BGRT 'status' field to zero to indicate that the BGRT
      image isn't being displayed, and we shouldn't be printing an
      error message in that case because it's just noise for users. So
      swap pr_err() for pr_debug().

      However, Josh points that out it still makes sense to test the
      validity of the upper 7 bits of the 'status' field, since
      they're marked as "reserved" in the spec and must be zero. If
      firmware violates this it really *is* an error.

      efi: Add support for EFI_MEMORY_RO attribute introduced by UEFIv2.5

      The UEFI spec v2.5 introduces a new memory attribute
      EFI_MEMORY_RO, which is now the preferred attribute to convey
      that the nature of the contents of such a region allows it to be
      mapped read-only (i.e., it contains .text and .rodata only).

      The specification of the existing EFI_MEMORY_WP attribute has been
      updated to align more closely with its common use as a
      cacheability attribute rather than a permission attribute.

      Add the #define and add the attribute to the memory map dumping
      routine.

      iommu/iova: Avoid over-allocating when size-aligned

      Currently, allocating a size-aligned IOVA region quietly adjusts the
      actual allocation size in the process, returning a rounded-up
      power-of-two-sized allocation. This results in mismatched behaviour in
      the IOMMU driver if the original size was not a power of two, where the
      original size is mapped, but the rounded-up IOVA size is unmapped.

      Whilst some IOMMUs will happily unmap already-unmapped pages, others
      consider this an error, so fix it by computing the necessary alignment
      padding without altering the actual allocation size. Also clean up by
      making pad_size unsigned, since its callers always pass unsigned values
      and negative padding makes little sense here anyway.

      Make asm/word-at-a-time.h available on all architectures

      Added the x86 implementation of word-at-a-time to the
      generic version, which previously only supported big-endian.

      Omitted the x86-specific load_unaligned_zeropad(), which in
      any case is also not present for the existing BE-only
      implementation of a word-at-a-time, and is only used under
      CONFIG_DCACHE_WORD_ACCESS.

      Added as a "generic-y" to the Kbuilds of all architectures
      that didn't previously have it.

      Merge tag 'arm64-upstream' of 
git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

      Pull arm64 updates from Catalin Marinas:

       - "genirq: Introduce generic irq migration for cpu hotunplugged" patch
         merged from tip/irq/for-arm to allow the arm64-specific part to be
         upstreamed via the arm64 tree

       - CPU feature detection reworked to cope with heterogeneous systems
         where CPUs may not have exactly the same features.  The features
         reported by the kernel via internal data structures or ELF_HWCAP are
         delayed until all the CPUs are up (and before user space starts)

       - Support for 16KB pages, with the additional bonus of a 36-bit VA
         space, though the latter only depending on EXPERT

       - Implement native {relaxed, acquire, release} atomics for arm64

       - New ASID allocation algorithm which avoids IPI on roll-over, together
         with TLB invalidation optimisations (using local vs global where
         feasible)

       - KASan support for arm64

       - EFI_STUB clean-up and isolation for the kernel proper (required by
         KASan)

       - copy_{to,from,in}_user optimisations (sharing the memcpy template)

       - perf: moving arm64 to the arm32/64 shared PMU framework

       - L1_CACHE_BYTES increased to 128 to accommodate Cavium hardware

       - Support for the contiguous PTE hint on kernel mapping (16 consecutive
         entries may be able to use a single TLB entry)

       - Generic CONFIG_HZ now used on arm64

       - defconfig updates

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

      Pull s390 updates from Martin Schwidefsky:
       "There is only one new feature in this pull for the 4.4 merge window,
        most of it is small enhancements, cleanup and bug fixes:

         - Add the s390 backend for the software dirty bit tracking.  This
           adds two new pgtable functions pte_clear_soft_dirty and
           pmd_clear_soft_dirty which is why there is a hit to
           arch/x86/include/asm/pgtable.h in this pull request.

         - A series of cleanup patches for the AP bus, this includes the
           removal of the support for two outdated crypto cards (PCICC and
           PCICA).

         - The irq handling / signaling on buffer full in the runtime
           instrumentation code is dropped.

         - Some micro optimizations: remove unnecessary memory barriers for a
           couple of functions: [smb_]rmb, [smb_]wmb, atomics, bitops, and for
           spin_unlock.  Use the builtin bswap if available and make
           test_and_set_bit_lock more cache friendly.

         - Statistics and a tracepoint for the diagnose calls to the
           hypervisor.

         - The CPU measurement facility support to sample KVM guests is
           improved.

         - The vector instructions are now always enabled for user space
           processes if the hardware has the vector facility.  This simplifies
           the FPU handling code.  The fpu-internal.h header is split into fpu
           internals, api and types just like x86.

         - Cleanup and improvements for the common I/O layer.

         - Rework udelay to solve a problem with kprobe.  udelay has busy loop
           semantics but still uses an idle processor state for the wait"

      Pull networking updates from David Miller:

      Changes of note:

       1) Allow to schedule ICMP packets in IPVS, from Alex Gartrell.

       2) Provide FIB table ID in ipv4 route dumps just as ipv6 does, from
          David Ahern.

       3) Allow the user to ask for the statistics to be filtered out of
          ipv4/ipv6 address netlink dumps.  From Sowmini Varadhan.

       4) More work to pass the network namespace context around deep into
          various packet path APIs, starting with the netfilter hooks.  From
          Eric W Biederman.

       5) Add layer 2 TX/RX checksum offloading to qeth driver, from Thomas
          Richter.

       6) Use usec resolution for SYN/ACK RTTs in TCP, from Yuchung Cheng.

       7) Support Very High Throughput in wireless MESH code, from Bob
          Copeland.

       8) Allow setting the ageing_time in switchdev/rocker.  From Scott
          Feldman.

       9) Properly autoload L2TP type modules, from Stephen Hemminger.

      10) Fix and enable offload features by default in 8139cp driver, from
          David Woodhouse.

      11) Support both ipv4 and ipv6 sockets in a single vxlan device, from
          Jiri Benc.

      12) Fix CWND limiting of thin streams in TCP, from Bendik Rønning
          Opstad.

      13) Fix IPSEC flowcache overflows on large systems, from Steffen
          Klassert.

      14) Convert bridging to track VLANs using rhashtable entries rather than
          a bitmap.  From Nikolay Aleksandrov.

      15) Make TCP listener handling completely lockless, this is a major
          accomplishment.  Incoming request sockets now live in the
          established hash table just like any other socket too.

          From Eric Dumazet.

      15) Provide more bridging attributes to netlink, from Nikolay
          Aleksandrov.

      16) Use hash based algorithm for ipv4 multipath routing, this was very
          long overdue.  From Peter Nørlund.

      17) Several y2038 cures, mostly avoiding timespec.  From Arnd Bergmann.

      18) Allow non-root execution of EBPF programs, from Alexei Starovoitov.

      19) Support SO_INCOMING_CPU as setsockopt, from Eric Dumazet.  This
          influences the port binding selection logic used by SO_REUSEPORT.

      20) Add ipv6 support to VRF, from David Ahern.

      21) Add support for Mellanox Spectrum switch ASIC, from Jiri Pirko.

      22) Add rtl8xxxu Realtek wireless driver, from Jes Sorensen.

      23) Implement RACK loss recovery in TCP, from Yuchung Cheng.

      24) Support multipath routes in MPLS, from Roopa Prabhu.

      25) Fix POLLOUT notification for listening sockets in AF_UNIX, from Eric
          Dumazet.

      26) Add new QED Qlogic river, from Yuval Mintz, Manish Chopra, and
          Sudarsana Kalluru.

      27) Don't fetch timestamps on AF_UNIX sockets, from Hannes Frederic
          Sowa.

      28) Support ipv6 geneve tunnels, from John W Linville.

      29) Add flood control support to switchdev layer, from Ido Schimmel.

      30) Fix CHECKSUM_PARTIAL handling of potentially fragmented frames, from
          Hannes Frederic Sowa.

      31) Support persistent maps and progs in bpf, from Daniel Borkmann.

      Merge branch 'perf-core-for-linus' of 
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

      Pull perf updates from Ingo Molnar:
       "Kernel side changes:

         - Improve accuracy of perf/sched clock on x86.  (Adrian Hunter)

         - Intel DS and BTS updates.  (Alexander Shishkin)

         - Intel cstate PMU support.  (Kan Liang)

         - Add group read support to perf_event_read().  (Peter Zijlstra)

         - Branch call hardware sampling support, implemented on x86 and
           PowerPC.  (Stephane Eranian)

         - Event groups transactional interface enhancements.  (Sukadev
           Bhattiprolu)

         - Enable proper x86/intel/uncore PMU support on multi-segment PCI
           systems.  (Taku Izumi)

         - ... misc fixes and cleanups.

        The perf tooling team was very busy again with 200+ commits, the full
        diff doesn't fit into lkml size limits.  Here's an (incomplete) list
        of the tooling highlights:

        New features:

         - Change the default event used in all tools (record/top): use the
           most precise "cycles" hw counter available, i.e. when the user
           doesn't specify any event, it will try using cycles:ppp, cycles:pp,
           etc and fall back transparently until it finds a working counter.
           (Arnaldo Carvalho de Melo)

         - Integration of perf with eBPF that, given an eBPF .c source file
           (or .o file built for the 'bpf' target with clang), will get it
           automatically built, validated and loaded into the kernel via the
           sys_bpf syscall, which can then be used and seen using 'perf trace'
           and other tools.

           (Wang Nan)

        Various user interface improvements:

         - Automatic pager invocation on long help output.  (Namhyung Kim)

         - Search for more options when passing args to -h, e.g.: (Arnaldo
           Carvalho de Melo)

              $ perf report -h interface

              Usage: perf report [<options>]

               --gtk    Use the GTK2 interface
               --stdio  Use the stdio interface
               --tui    Use the TUI interface

         - Show ordered command line options when -h is used or when an
           unknown option is specified.  (Arnaldo Carvalho de Melo)

         - If options are passed after -h, show just its descriptions, not all
           options.  (Arnaldo Carvalho de Melo)

         - Implement column based horizontal scrolling in the hists browser
           (top, report), making it possible to use the TUI for things like
           'perf mem report' where there are many more columns than can fit in
           a terminal.  (Arnaldo Carvalho de Melo)

         - Enhance the error reporting of tracepoint event parsing, e.g.:

             $ oldperf record -e sched:sched_switc usleep 1
             event syntax error: 'sched:sched_switc'
                                  \___ unknown tracepoint
             Run 'perf list' for a list of valid events

           Now we get the much nicer:

             $ perf record -e sched:sched_switc ls
             event syntax error: 'sched:sched_switc'
                                  \___ can't access trace events

             Error: No permissions to read 
/sys/kernel/debug/tracing/events/sched/sched_switc
             Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug'

           And after we have those mount point permissions fixed:

             $ perf record -e sched:sched_switc ls
             event syntax error: 'sched:sched_switc'
                                  \___ unknown tracepoint

             Error: File /sys/kernel/debug/tracing/events/sched/sched_switc not 
found.
             Hint:  Perhaps this kernel misses some CONFIG_ setting to enable 
this feature?.

           I.e.  basically now the event parsing routing uses the 
strerror_open()
           routines introduced by and used in 'perf trace' work.  (Jiri Olsa)

         - Fail properly when pattern matching fails to find a tracepoint,
           i.e. '-e non:existent' was being correctly handled, with a proper
           error message about that not being a valid event, but '-e
           non:existent*' wasn't, fix it.  (Jiri Olsa)

         - Do event name substring search as last resort in 'perf list'.
           (Arnaldo Carvalho de Melo)

        Intel PT hardware tracing enhancements:

         - Accept a zero --itrace period, meaning "as often as possible".  In
           the case of Intel PT that is the same as a period of 1 and a unit
           of 'instructions' (i.e.  --itrace=i1i).  (Adrian Hunter)

         - Harmonize itrace's synthesized callchains with the existing
           --max-stack tool option.  (Adrian Hunter)

         - Allow time to be displayed in nanoseconds in 'perf script'.
           (Adrian Hunter)

         - Fix potential infinite loop when handling Intel PT timestamps.
           (Adrian Hunter)

         - Slighly improve Intel PT debug logging.  (Adrian Hunter)

         - Warn when AUX data has been lost, just like when processing
           PERF_RECORD_LOST.  (Adrian Hunter)

         - Further document export-to-postgresql.py script.  (Adrian Hunter)

         - Add option to synthesize branch stack from auxtrace data.  (Adrian
           Hunter)

        Misc notable changes:

         - Switch the default callchain output mode to 'graph,0.5,caller', to
           make it look like the default for other tools, reducing the
           learning curve for people used to 'caller' based viewing.  (Arnaldo
           Carvalho de Melo)

         - various call chain usability enhancements.  (Namhyung Kim)

         - Introduce the 'P' event modifier, meaning 'max precision level,
           please', i.e.:

              $ perf record -e cycles:P usleep 1

           Is now similar to:

              $ perf record usleep 1

           Useful, for instance, when specifying multiple events.  (Jiri Olsa)

         - Add 'socket' sort entry, to sort by the processor socket in 'perf
           top' and 'perf report'.  (Kan Liang)

         - Introduce --socket-filter to 'perf report', for filtering by
           processor socket.  (Kan Liang)

         - Add new "Zoom into Processor Socket" operation in the perf hists
           browser, used in 'perf top' and 'perf report'.  (Kan Liang)

         - Allow probing on kmodules without DWARF.  (Masami Hiramatsu)

         - Fix 'perf probe -l' for probes added to kernel module functions.
           (Masami Hiramatsu)

         - Preparatory work for the 'perf stat record' feature that will allow
           generating perf.data files with counting data in addition to the
           sampling mode we have now (Jiri Olsa)

         - Update libtraceevent KVM plugin.  (Paolo Bonzini)

      atomic: remove all traces of READ_ONCE_CTRL() and atomic*_read_ctrl()

      This seems to be a mis-reading of how alpha memory ordering works, and
      is not backed up by the alpha architecture manual.  The helper functions
      don't do anything special on any other architectures, and the arguments
      that support them being safe on other architectures also argue that they
      are safe on alpha.

      Basically, the "control dependency" is between a previous read and a
      subsequent write that is dependent on the value read.  Even if the
      subsequent write is actually done speculatively, there is no way that
      such a speculative write could be made visible to other cpu's until it
      has been committed, which requires validating the speculation.

      Note that most weakely ordered architectures (very much including alpha)
      do not guarantee any ordering relationship between two loads that depend
      on each other on a control dependency:

          read A
          if (val == 1)
              read B

      because the conditional may be predicted, and the "read B" may be
      speculatively moved up to before reading the value A.  So we require the
      user to insert a smp_rmb() between the two accesses to be correct:

          read A;
          if (A == 1)
              smp_rmb()
              read B

      Alpha is further special in that it can break that ordering even if the
      *address* of B depends on the read of A, because the cacheline that is
      read later may be stale unless you have a memory barrier in between the
      pointer read and the read of the value behind a pointer:

          read ptr
          read offset(ptr)

      whereas all other weakly ordered architectures guarantee that the data
      dependency (as opposed to just a control dependency) will order the two
      accesses.  As a result, alpha needs a "smp_read_barrier_depends()" in
      between those two reads for them to be ordered.

      The coontrol dependency that "READ_ONCE_CTRL()" and "atomic_read_ctrl()"
      had was a control dependency to a subsequent *write*, however, and
      nobody can finalize such a subsequent write without having actually done
      the read.  And were you to write such a value to a "stale" cacheline
      (the way the unordered reads came to be), that would seem to lose the
      write entirely.

      So the things that make alpha able to re-order reads even more
      aggressively than other weak architectures do not seem to be relevant
      for a subsequent write.  Alpha memory ordering may be strange, but
      there's no real indication that it is *that* strange.

      Also, the alpha architecture reference manual very explicitly talks
      about the definition of "Dependence Constraints" in section 5.6.1.7,
      where a preceding read dominates a subsequent write.

      Such a dependence constraint admittedly does not impose a BEFORE (alpha
      architecture term for globally visible ordering), but it does guarantee
      that there can be no "causal loop".  I don't see how you could avoid
      such a loop if another cpu could see the stored value and then impact
      the value of the first read.  Put another way: the read and the write
      could not be seen as being out of order wrt other cpus.

      So I do not see how these "x_ctrl()" functions can currently be necessary.

      I may have to eat my words at some point, but in the absense of clear
      proof that alpha actually needs this, or indeed even an explanation of
      how alpha could _possibly_ need it, I do not believe these functions are
      called for.

      And if it turns out that alpha really _does_ need a barrier for this
      case, that barrier still should not be "smp_read_barrier_depends()".
      We'd have to make up some new speciality barrier just for alpha, along
      with the documentation for why it really is necessary.

       "The main changes in this cycle were:

         - More gradual enhancements to atomic ops: new atomic*_read_ctrl()
           ops, synchronize atomic_{read,set}() ordering requirements between
           architectures, add atomic_long_t bitops.  (Peter Zijlstra)

         - Add _{relaxed|acquire|release}() variants for inc/dec atomics and
           use them in various locking primitives: mutex, rtmutex, mcs, rwsem.
           This enables weakly ordered architectures (such as arm64) to make
           use of more locking related optimizations.  (Davidlohr Bueso)

         - Implement atomic[64]_{inc,dec}_relaxed() on ARM.  (Will Deacon)

         - Futex kernel data cache footprint micro-optimization.  (Rasmus
           Villemoes)

         - pvqspinlock runtime overhead micro-optimization.  (Waiman Long)

         - Enable imprecise aborts early, so that bus errors aren't masked

           loaders which provoke these aborts can cause the kernel to crash
           early in boot, so we install a handler to report this event around
           the site where these are enabled.

         - Add unwinding annotations to some assembly code.

         - Reduce ioremap() alignment for SMP/LPAE cases where we don't need

      ide: pdc202xx_new: Replace timeval with ktime_t

      This driver uses 'struct timeval' which we are trying to remove since
      32 bit time types will break in the year 2038 by replacing it with
      ktime_t.

      This patch changes do_gettimeofday() to ktime_get() because
      ktime_get() returns a ktime_t while do_gettimeofday() returns struct
      timeval.

      This patch also uses ktime_us_delta() to get the elapsed time.

      net: dsa: mv88e6xxx: include DSA ports in VLANs

      DSA ports must be members of a VLAN in order to ensure frame bridging
      between chained switch chips.

      Thus tag them in addition to the CPU port when adding a VLAN, and skip
      them when deleting a VLAN and reporting VLAN members.

      Also use the UNMODIFIED egress policy, so that frames egress on these
      ports as they ingress, tagged or untagged.

      net/core: fix for_each_netdev_feature

      As pointed out by Nikolay and further explained by Geert, the initial
      for_each_netdev_feature macro was broken, as feature would get set outside
      of the block of code it was intended to run in, thus only ever working for
      the first feature bit in the mask. While less pretty this way, this is
      tested and confirmed functional with multiple feature bits set in
      NETIF_F_UPPER_DISABLES.

      Depending on the gcc version we can use builtin_bswap instead of
      architecture functions. Doing so is better than the inline assembly
      version of load reverse for two reasons:
      - the sequence of load reversed, apply constant mask, save reversed can
        be optimized to load, apply reversed mask, save
      - builtins are slightly better to optimize e.g. gcc instruction
        scheduler cannot optimize grouping on inline assemblies.

      To enable set we have to ARCH_USE_BUILTIN_BSWAP.

      s390/dasd: fix disconnected device with valid path mask

      Path verification is either done via dasd_eckd_read_conf() which is
      triggered during online processing and resume or via
      do_path_verification_work() which is triggered after path events.
      The dasd_eckd_read_conf() version added paths unconditionally and did
      not check if the path mask was empty. This led to devices having the
      disconnected stop flag set but a valid path mask. So they where not
      working although they had paths validated successfully. After a resume
      this state could even not be solved with additional paths added.

      Fix by checking for an empty path mask in dasd_eckd_read_conf() and
      clearing the device stop bits for a newly added channel path.

      s390/dasd: fix invalid PAV assignment after suspend/resume

      For a valid PAV assignment the DASD driver needs to notice possibly
      changed configuration data. Thus the failing of read configuration
      data should also fail the device restore to prevent invalid PAV
      assignment. The failed device may get restored after additional paths
      get available later on.
      If the restore fails after the device was added to the lcu alias
      handling it needs to be removed from the alias handling before exiting
      the restore function.

      mac80211: fixup AIFSN instead of disabling WMM

      Disabling WMM has a huge impact these days. It implies that
      HT and VHT will be disabled which means that the throughput
      will be drammatically reduced.
      Since the AIFSN is a transmission parameter, we can play a
      bit and fix it up to make it compliant with the 802.11
      specification which requires it to be at least 2.
      Increasing it from 1 to 2 will slightly reduce the
      likelyhood to get a transmission opportunity compared to
      other clients that would accept to set AIFSN=1, but at
      least it will allow HT and VHT which is a huge gain.

          shouldn't expect for hw_restart anyway, so we can
          simply cancel it (on resume).

      * wowlan is configured, drv_resume() == 1
          There is no definitive expected behavior in this case,
          as each driver might have different expectations (e.g.
          setting some flags on suspend/restart vs. not handling
          spurious recovery).
          For now, simply let the hw_restart work run again after
          resume, and hope the driver will handle it well (or at
          least initiate another hw restart).

      This also introduces a additionnal DT binding for the GPIO extension bus

      net: phy: fix a bug in get_phy_c45_ids

      When probing devices-in-package for a c45 phy, device zero is the last
      device to probe, however, if driver reads 0 from device zero,
      c45_ids->devices_in_package is set to '0', the loop condition of probing
      will be matched again, see codes below:

      for (i = 1;i < num_ids && c45_ids->devices_in_package == 0;i++)

      driver will run in a dead loop.

      This patch restructures the bug and confusing loop, it provides a helper
      function get_phy_c45_devs_in_pkg which to read devices-in-package 
registers
      of a MMD, and rewrites the loop with using the helper function.

      net/core: generic support for disabling netdev features down stack

      There are some netdev features, which when disabled on an upper device,
      such as a bonding master or a bridge, must be disabled and cannot be
      re-enabled on underlying devices.

      This is a rework of an earlier more heavy-handed appraoch, which simply
      disables and prevents re-enabling of netdev features listed in a new
      define in include/net/netdev_features.h, NETIF_F_UPPER_DISABLES. Any upper
      device that disables a flag in that feature mask, the disabling will
      propagate down the stack, and any lower device that has any upper device
      with one of those flags disabled should not be able to enable said flag.

      Initially, only LRO is included for proof of concept, and because this
      code effectively does the same thing as dev_disable_lro(), though it will
      also activate from the ethtool path, which was one of the goals here.

      [root@dell-per730-01 ~]# ethtool -k bond0 |grep large
      large-receive-offload: on
      [root@dell-per730-01 ~]# ethtool -k p5p1 |grep large
      large-receive-offload: on
      [root@dell-per730-01 ~]# ethtool -K bond0 lro off
      [root@dell-per730-01 ~]# ethtool -k bond0 |grep large
      large-receive-offload: off
      [root@dell-per730-01 ~]# ethtool -k p5p1 |grep large
      large-receive-offload: off

      dmesg dump:

      [ 1033.277986] bond0: Disabling feature 0x0000000000008000 on lower dev 
p5p2.
      [ 1034.067949] bnx2x 0000:06:00.1 p5p2: using MSI-X  IRQs: sp 74  fp[0]

      [ 1034.753612] bond0: Disabling feature 0x0000000000008000 on lower dev

64 ... fp[7] 71

      This has been successfully tested with bnx2x, qlcnic and netxen network
      cards as slaves in a bond interface. Turning LRO on or off on the master
      also turns it on or off on each of the slaves, new slaves are added with
      LRO in the same state as the master, and LRO can't be toggled on the
      slaves.

      Also, this should largely remove the need for dev_disable_lro(), and most,
      if not all, of its call sites can be replaced by simply making sure
      NETIF_F_LRO isn't included in the relevant device's feature flags.

      Note that this patch is driven by bug reports from users saying it was
      confusing that bonds and slaves had different settings for the same
      features, and while it won't be 100% in sync if a lower device doesn't
      support a feature like LRO, I think this is a good step in the right
      direction.

      sfc: push partner queue for skb->xmit_more

      When the IP stack passes SKBs the sfc driver puts them in 2 different TX
      queues (called partners), one for checksummed and one for not checksummed.
      If the SKB has xmit_more set the driver will delay pushing the work to the
      NIC.

      When later it does decide to push the buffers this patch ensures it also
      pushes the partner queue, if that also has any delayed work. Before this
      fix the work in the partner queue would be left for a long time and cause
      a netdev watchdog.

      ====================
      re-org actor admin/oper key updates

      I was observing machines entering into weird LACP state when the
      partner is in passive mode. This issue is not because of the partners
      in passive state but probably because of some operational key update
      which is pushing the state-machine is that weird state. This was
      happening randomly on about 1% of the machine (when the sample size
      is a large set of machines with a variety of NICs/ports bonded).

      In this patch-series I'm attempting to unify the logic of actor-key
      / operational-key changes to one place to avoid possible errors in
      update. Also this eliminates the need for the event-handler to decide
      if the key needs update.

      After this patch-set none of the machines (from same sample set) were
      exhibiting LACP-weirdness that was observed earlier.

        (a) If port is "duplex" then only it can participate in LACP

      bpf: add sample usages for persistent maps/progs

        bpf: fd:3 l->(1):42 ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/m -G -m -k 1 -v 24

        bpf: fd:3 u->(1:24) ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/m -G -m -k 1
        bpf: get fd:3 (Success)
        bpf: fd:3 l->(1):24 ret:(0,Success)

        # ./fds_example -F /sys/fs/bpf/m2 -P -m
        bpf: map fd:3 (Success)
        bpf: pin ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/m2 -G -m -k 1
        bpf: get fd:3 (Success)
        bpf: fd:3 l->(1):0 ret:(0,Success)
        # ./fds_example -F /sys/fs/bpf/m2 -G -m
        bpf: get fd:3 (Success)

      Example with progs:

        # ./fds_example -F /sys/fs/bpf/p -P -p
        bpf: prog fd:3 (Success)
        bpf: pin ret:(0,Success)

        # ./fds_example -F /sys/fs/bpf/p -G -p

      bpf: add support for persistent maps/progs

      This work adds support for "persistent" eBPF maps/programs. The term
      "persistent" is to be understood that maps/programs have a facility
      that lets them survive process termination. This is desired by various
      eBPF subsystem users.

      Just to name one example: tc classifier/action. Whenever tc parses
      the ELF object, extracts and loads maps/progs into the kernel, these
      file descriptors will be out of reach after the tc instance exits.
      So a subsequent tc invocation won't be able to access/relocate on this
      resource, and therefore maps cannot easily be shared, f.e. between the
      ingress and egress networking data path.

      The current workaround is that Unix domain sockets (UDS) need to be
      instrumented in order to pass the created eBPF map/program file
      descriptors to a third party management daemon through UDS' socket
      passing facility. This makes it a bit complicated to deploy shared
      eBPF maps or programs (programs f.e. for tail calls) among various
      processes.

      We've been brainstorming on how we could tackle this issue and various
      approches have been tried out so far, which can be read up further in
      the below reference.

      The architecture we eventually ended up with is a minimal file system
      that can hold map/prog objects. The file system is a per mount namespace
      singleton, and the default mount point is /sys/fs/bpf/. Any subsequent
      mounts within a given namespace will point to the same instance. The
      file system allows for creating a user-defined directory structure.
      The objects for maps/progs are created/fetched through bpf(2) with
      two new commands (BPF_OBJ_PIN/BPF_OBJ_GET). I.e. a bpf file descriptor
      along with a pathname is being passed to bpf(2) that in turn creates
      (we call it eBPF object pinning) the file system nodes. Only the pathname
      is being passed to bpf(2) for getting a new BPF file descriptor to an
      existing node. The user can use that to access maps and progs later on,
      through bpf(2). Removal of file system nodes is being managed through
      normal VFS functions such as unlink(2), etc. The file system code is
      kept to a very minimum and can be further extended later on.

      The next step I'm working on is to add dump eBPF map/prog commands
      to bpf(2), so that a specification from a given file descriptor can
      be retrieved. This can be used by things like CRIU but also applications
      can inspect the meta data after calling BPF_OBJ_GET.

      Big thanks also to Alexei and Hannes who significantly contributed
      in the design discussion that eventually let us end up with this
      architecture here.

      We currently have duplicated cleanup code in bpf_prog_put() and
      bpf_prog_put_rcu() cleanup paths. Back then we decided that it was
      not worth it to make it a common helper called by both, but with
      the recent addition of resource charging, we could have avoided
      the fix in commit ac00737f4e81 ("bpf: Need to call 
bpf_prog_uncharge_memlock
      from bpf_prog_put") if we would have had only a single, common path.
      We can simplify it further by assigning aux->prog only once during
      allocation time.

      bpf: align and clean bpf_{map,prog}_get helpers

      Add a bpf_map_get() function that we're going to use later on and
      align/clean the remaining helpers a bit so that we have them a bit
      more consistent:

        - __bpf_map_get() and __bpf_prog_get() that both work on the fd
          struct, check whether the descriptor is eBPF and return the
          pointer to the map/prog stored in the private data.

          Also, we can return f.file->private_data directly, the function
          signature is enough of a documentation already.

        - bpf_map_get() and bpf_prog_get() that both work on u32 user fd,
          call their respective __bpf_map_get()/__bpf_prog_get() variants,

      bpf: abstract anon_inode_getfd invocations

      Since we're going to use anon_inode_getfd() invocations in more than just
      the current places, make a helper function for both, so that we only need
      to pass a map/prog pointer to the helper itself in order to get a fd. The
      new helpers are called bpf_map_new_fd() and bpf_prog_new_fd().

      net: fix percpu memory leaks

      This patch fixes following problems :

      1) percpu_counter_init() can return an error, therefore
        init_frag_mem_limit() must propagate this error so that
        inet_frags_init_net() can do the same up to its callers.

      2) If ip[46]_frags_ns_ctl_register() fail, we must unwind
         properly and free the percpu_counter.

      Without this fix, we leave freed object in percpu_counters
      global list (if CONFIG_HOTPLUG_CPU) leading to crashes.

      This bug was detected by KASAN and syzkaller tool
      (http://github.com/google/syzkaller)

      ipv6: fix crash on ICMPv6 redirects with prohibited/blackholed source

      There are other error values besides ip6_null_entry that can be returned 
by
      ip6_route_redirect(): fib6_rule_action() can also result in
      ip6_blk_hole_entry and ip6_prohibit_entry if such ip rules are installed.

      Only checking for ip6_null_entry in rt6_do_redirect() causes ip6_ins_rt()
      to be called with rt->rt6i_table == NULL in these cases, making the kernel
      crash.

      net: make skb_set_owner_w() more robust

      skb_set_owner_w() is called from various places that assume
      skb->sk always point to a full blown socket (as it changes
      sk->sk_wmem_alloc)

      We'd like to attach skb to request sockets, and in the future
      to timewait sockets as well. For these kind of pseudo sockets,
      we need to take a traditional refcount and use sock_edemux()
      as the destructor.

      It is now time to un-inline skb_set_owner_w(), being too big.

      qmi_wwan: fix entry for HP lt4112 LTE/HSPA+ Gobi 4G Module

      The lt4112 is a HP branded Huawei me906e modem. Like other Huawei
      modems, it does not have a fixed interface to function mapping.
      Instead it uses a Huawei specific scheme: functions are mapped by
      subclass and protocol.

      However, the HP vendor ID is used for modems from many different
      manufacturers using different schemes, so we cannot apply a generic
      vendor rule like we do for the Huawei vendor ID.

      Replace the previous lt4112 entry pointing to an arbitrary interface
      number with a device specific subclass + protocol match.

      Merge tag 'gpio-v4.4-1' of 
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

      Pull GPIO updates from Linus Walleij:
       "Here is the bulk of GPIO changes for the v4.4 development cycle.

        The only changes hitting outside drivers/gpio are in the pin control
        subsystem and these seem to have settled nicely in linux-next.

        Development mistakes and catfights are nicely documented in the
        reverts as you can see.  The outcome of the ABI fight is that we're
        working on a chardev ABI for GPIO now, where hope to show results for
        the v4.5 kernel.

        Summary of changes:

        GPIO core:
         - Define and handle flags for open drain/open collector and open
           source/open emitter, also know as "single-ended" configurations.
         - Generic request/free operations that handle calling out to the
           (optional) pin control backend.
         - Some refactoring related to an ABI change that did not happen, yet
           provide useful.
         - Added a real-time compliance checklist.  Many GPIO chips have
           irqchips, and need to think this over with the RT patches going
           upstream.
         - Restructure, fix and clean up Kconfig menus a bit.

        New drivers:
         - New driver for AMD Promony.
         - New driver for ACCES 104-IDIO-16, a port-mapped I/O card,
           ISA-style.  Very retro.

        Subdriver changes:
         - OMAP changes to handle real time requirements.
         - Handle trigger types for edge and level IRQs on PL061 properly.  As
           this hardware is very common it needs to set a proper example for
           others to follow.
         - Some container_of() cleanups.
         - Delete the unused MSM driver in favor of the driver that is
           embedded inside the pin control driver.
         - Cleanup of the ath79 GPIO driver used by many, many OpenWRT router
           targets.
         - A consolidated IT87xx driver replacing the earlier very specific
           IT8761e driver.
         - Handle the TI TCA9539 in the PCA953x driver.  Also handle ACPI
           devices in this subdriver.
         - Drop xilinx arch dependencies as these FPGAs seem to profilate over
           a few different architectures.  MIPS and ARM come to mind"

      the common mv88e6xxx code.

      In the meantime make __mv88e6xxx_reg_{read,write} static since we do not

      bridge: vlan: Prevent possible use-after-free

      When adding a port to a bridge we initialize VLAN filtering on it. We do
      not bail out in case an error occurred in nbp_vlan_init, as it can be
      used as a non VLAN filtering bridge.

      However, if VLAN filtering is required and an error occurred in
      nbp_vlan_init, we should set vlgrp to NULL, so that VLAN filtering
      functions (e.g. br_vlan_find, br_get_pvid) will know the struct is
      invalid and will not try to access it.

      tcp/dccp: fix ireq->pktopts race

      IPv6 request sockets store a pointer to skb containing the SYN packet
      to be able to transfer it to full blown socket when 3WHS is done
      (ireq->pktopts -> np->pktoptions)

      As explained in commit 5e0724d027f0 ("tcp/dccp: fix hashdance race for
      passive sessions"), we must transfer the skb only if we won the
      hashdance race, if multiple cpus receive the 'ack' packet completing
      3WHS at the same time.

      RDS: convert bind hash table to re-sizable hashtable

      To further improve the RDS connection scalabilty on massive systems
      where number of sockets grows into tens of thousands  of sockets, there
      is a need of larger bind hashtable. Pre-allocated 8K or 16K table is
      not very flexible in terms of memory utilisation. The rhashtable
      infrastructure gives us the flexibility to grow the hashtbable based
      on use and also comes up with inbuilt efficient bucket(chain) handling.

      Pull pin control updates from Linus Walleij:
       "This is the big bulk of pin control changes for the v4.4 kernel
        development cycle.  Development pace is high in pin control again this
        merge window.  28 contributors, 83 patches.

        It hits a few sites outside the pin control subsystem:

         - Device tree bindings in Documentation (as usual)
         - MAINTAINERS
         - drivers/base/* for the "init" state handling by Doug Anderson.
           This has been ACKed by Greg.
         - drivers/usb/renesas_usbhs/rcar2.c, for a dependent Renesas change
           in the USB subsystem.  This has been ACKed by both Greg and Felipe.
         - arch/arm/boot/dts/sama5d2.dtsi - this should ideally have gone
           through the ARM SoC tree but ended up here.

        This time I am using Geert Uytterhoeven as submaintainer for SH PFC
        since the are three-four people working in parallel with new Renesas
        ASICs.

        Summary of changes:

        Infrastructure:

         - Doug Anderson wrote a patch adding an "init" state different from
           the "default" state for pin control state handling in the core
           framework.  This is applied before the driver's probe() call if
           defined and takes precedence over "default".  If both are defined,
           "init" will be applied *before* probe() and "default" will be
           applied *after* probe().

        Significant subdriver improvements:

         - SH PFC is switched to getting GPIO ranges from the device tree
           ranges property on DT platforms.
         - Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all modernized.
         - Got rid of SH PFC hardcoded IRQ numbers.
         - Allwinner sunxi external interrupt through the "r" controller.
         - Moved the Cygnus driver to use DT-provided GPIO ranges.

        New drivers:

         - Atmel PIO4 pin controller for the SAMA4D2 family

        New subdrivers:

         - Rockchip RK3036 subdriver
         - Renesas SH PFC R8A7795 subdriver
         - Allwinner sunxi A83T PIO subdriver
         - Freescale i.MX7d iomux lpsr subdriver
         - Marvell Berlin BG4CT subdriver
         - SiRF Atlas 7 step B SoC subdriver
         - Intel Broxton SoC subdriver

        Apart from this, the usual slew if syntactic and semantic fixes"

      a module but the module alias information is not added to the module info
      so module autoload won't work since user-space won't have the information.

      net: encx24j600: Fix SPI id table definition

      A driver's SPI id table is expected to be an array of struct spi_device_id
      that ends with a zero-initialized sentinel entry. But this driver defines
      the table as a single struct spi_device_id and sets .id_table to a pointer
      to this struct.

      But spi_match_id() has a loop that iterates while the struct spi_device_id
      .name[0] is not NULL, so not having a sentinel can cause a NULL pointer
      deference error.

      This patch defines the SPI id table correctly as all other SPI drivers do.

      ipv4: use l4 hash for locally generated multipath flows

      This patch changes how the multipath hash is computed for locally
      generated flows: now the hash comprises l4 information.

      This allows better utilization of the available paths when the existing
      flows have the same source IP and the same destination IP: with l3 hash,
      even when multiple connections are in place simultaneously, a single path
      will be used, while with l4 hash we can use all the available paths.

      v2 changes:
      - use get_hash_from_flowi4() instead of implementing just another l4 hash
        function

      mm: get rid of 'vmalloc_info' from /proc/meminfo

      It turns out that at least some versions of glibc end up reading
      /proc/meminfo at every single startup, because glibc wants to know the
      amount of memory the machine has.  And while that's arguably insane,
      it's just how things are.

      And it turns out that it's not all that expensive most of the time, but
      the vmalloc information statistics (amount of virtual memory used in the
      vmalloc space, and the biggest remaining chunk) can be rather expensive
      to compute.

      The 'get_vmalloc_info()' function actually showed up on my profiles as
      4% of the CPU usage of "make test" in the git source repository, because
      the git tests are lots of very short-lived shell-scripts etc.

      It turns out that apparently this same silly vmalloc info gathering
      shows up on the facebook servers too, according to Dave Jones.  So it's
      not just "make test" for git.

      We had two patches to just cache the information (one by me, one by
      Ingo) to mitigate this issue, but the whole vmalloc information of of
      rather dubious value to begin with, and people who *actually* want to
      know what the situation is wrt the vmalloc area should just look at the
      much more complete /proc/vmallocinfo instead.

      In fact, according to my testing - and perhaps more importantly,
      according to that big search engine in the sky: Google - there is
      nothing out there that actually cares about those two expensive fields:
      VmallocUsed and VmallocChunk.

      So let's try to just remove them entirely.  Actually, this just removes
      the computation and reports the numbers as zero for now, just to try to
      be minimally intrusive.

      If this breaks anything, we'll obviously have to re-introduce the code
      to compute this all and add the caching patches on top.  But if given
      the option, I'd really prefer to just remove this bad idea entirely
      rather than add even more code to work around our historical mistake
      that likely nobody really cares about.

      Merge branch 'fs-file-descriptor-optimization'

      Merge file descriptor allocation speedup.

      Eric Dumazet has a test-case for a fairly common network deamon load
      pattern: openign and closing a lot of sockets that each have very little
      work done on them.  It turns out that in that case, the cost of just
      finding the correct file descriptor number can be a dominating factor.

      We've long had a trivial optimization for allocating file descriptors
      sequentially, but that optimization ends up being not very effective
      when other file descriptors are being closed concurrently, and the fd
      patterns are not some simple FIFO pattern.  In such cases we ended up
      spending a lot of time just scanning the bitmap of open file descriptors
      in order to find the next file descriptor number to open.

      This trivial patch-series mitigates that by simply introducing a
      second-level bitmap of which words in the first bitmap are already fully
      allocated.  That cuts down the cost of scanning by an order of magnitude
      in some pathological (but realistic) cases.

      The second patch is an even more trivial patch to avoid unnecessarily
      dirtying the cacheline for the close-on-exec bit array that normally
      ends up being all empty.

      Use 64-bit timekeeping

      This patch changes the use of struct timespec in
      dccp_probe to use struct timespec64 instead. timespec uses a 32-bit
      seconds field which will overflow in the year 2038 and beyond. timespec64
      uses a 64-bit seconds field. Note that the correctness of the code isn't
      changed, since the original code only uses the timestamps to compute a
      small elapsed interval. This patch is part of a larger attempt to remove
      instances of 32-bit timekeeping structures (timespec, timeval, time_t)
      from the kernel so it is easier to identify where the real 2038 issues
      are.

      ipv4: update RTNH_F_LINKDOWN flag on UP event

      When nexthop is part of multipath route we should clear the
      LINKDOWN flag when link goes UP or when first address is added.
      This is needed because we always set LINKDOWN flag when DEAD flag
      was set but now on UP the nexthop is not dead anymore. Examples when
      LINKDOWN bit can be forgotten when no NETDEV_CHANGE is delivered:

      - link goes down (LINKDOWN is set), then link goes UP and device
      shows carrier OK but LINKDOWN remains set

      - last address is deleted (LINKDOWN is set), then address is
      added and device shows carrier OK but LINKDOWN remains set

      Steps to reproduce:
      modprobe dummy
      ifconfig dummy0 192.168.168.1 up

      here add a multipath route where one nexthop is for dummy0:

      ip route add 1.2.3.4 nexthop dummy0 nexthop SOME_OTHER_DEVICE
      ifconfig dummy0 down
      ifconfig dummy0 up

      now ip route shows nexthop that is not dead. Now set the sysctl var:

      echo 1 > /proc/sys/net/ipv4/conf/dummy0/ignore_routes_with_linkdown

      now ip route will show a dead nexthop because the forgotten
      RTNH_F_LINKDOWN is propagated as RTNH_F_DEAD.

      ipv4: fix to not remove local route on link down

      When fib_netdev_event calls fib_disable_ip on NETDEV_DOWN event
      we should not delete the local routes if the local address
      is still present. The confusion comes from the fact that both
      fib_netdev_event and fib_inetaddr_event use the NETDEV_DOWN
      constant. Fix it by returning back the variable 'force'.

      Steps to reproduce:
      modprobe dummy

      PHY driver uses DELAYED_WORK in order to maintain its state. Attempting

      message buffers is not prepared for the case that those may be

      We now linearize all such buffers before they are delivered up to the

      x86/cpu: Add CLZERO detection

      AMD Fam17h processors introduce support for the CLZERO
      instruction. It zeroes out the 64 byte cache line specified in
      RAX.

      Add the bit here to allow /proc/cpuinfo to list the feature.

      Boris: we're adding this as a separate ->x86_capability leaf
      because CPUID_80000008_EBX is going to contain more feature bits
      and it will fill out with time.

      gpio: fix up SPI submenu

      - Relax dependencies on SPI_MASTER for drivers in the SPI menu
        that already has this dependency.
      - Move out the expander that would be hidden for I2C access if
        SPI_MASTER was not selected. Tentatively create a separate
        menu for this.
      - Move the ZX SoC driver to memory-mapped drivers, this must be
        a mistake and only worked because the system has an SPI master
        enabled at the same time.

      vfs: conditionally clear close-on-exec flag

      We clear the close-on-exec flag when opening and closing files, and the
      bit was almost always already clear before.  Avoid dirtying the
      cacheline if the clearning isn't necessary.  That avoids unnecessary
      cacheline dirtying and bouncing in multi-socket environments.

      Eric Dumazet has a file descriptor benchmark that goes 4% faster from
      this on his two-socket machine.  It's probably partly superlinear
      improvement due to getting slightly less spinlock contention on the
      file_lock spinlock due to less work in the critical section.

      vfs: Fix pathological performance case for __alloc_fd()

      Al Viro points out that:
      > >     * [Linux-specific aside] our __alloc_fd() can degrade quite badly
      > > with some use patterns.  The cacheline pingpong in the bitmap is 
probably
      > > inevitable, unless we accept considerably heavier memory footprint,
      > > but we also have a case when alloc_fd() takes O(n) and it's _not_ hard
      > > to trigger - close(3);open(...); will have the next open() after that
      > > scanning the entire in-use bitmap.

      And Eric Dumazet has a somewhat realistic multithreaded microbenchmark
      that opens and closes a lot of sockets with minimal work per socket.

      This patch largely fixes it.  We keep a 2nd-level bitmap of the open
      file bitmaps, showing which words are already full.  So then we can
      traverse that second-level bitmap to efficiently skip already allocated
      file descriptors.

      On his benchmark, this improves performance by up to an order of
      magnitude, by avoiding the excessive open file bitmap scanning.

      When GPIO 0x4c changes we call ASL method _E4C which tries to read HELD
      field (the same GPIO). This triggers following error on the console:

          ACPI Error: Method parse/execution failed [\_SB.GPO0._E4C]
              (Node ffff88013f4b4438), AE_ERROR (20150930/psparse-542)

      The error happens because ACPI GPIO operation region handler
      (acpi_gpio_adr_space_handler()) tries to acquire the very same GPIO which
      returns an error (-EBUSY) because the GPIO is already reserved for the 
GPIO
      event.

      Fix this so that we "borrow" the event GPIO if we find the GPIO belongs to
      an event. Allow this only for GPIOs that are read.

      To be able to go through acpi_gpio->events list for operation region 
access
      we need to make sure the list is properly initialized whenever GPIO chip 
is
      registered.

      Revert "md: allow a partially recovered device to be hot-added to an 
array."

      This reverts commit 7eb418851f3278de67126ea0c427641ab4792c57.

      This commit is poorly justified, I can find not discusison in email,
      and it clearly causes a problem.

      If a device which is being recovered fails and is subsequently
      re-added to an array, there could easily have been changes to the
      array *before* the point where the recovery was up to.  So the
      recovery must start again from the beginning.

      If a spare is being recovered and fails, then when it is re-added we
      really should do a bitmap-based recovery up to the recovery-offset,
      and then a full recovery from there.  Before this reversion, we only
      did the "full recovery from there" which is not corect.  After this
      reversion with will do a full recovery from the start, which is safer
      but not ideal.

      It will be left to a future patch to arrange the two different styles
      of recovery.

      md/raid5: fix locking in handle_stripe_clean_event()

      After commit 566c09c53455 ("raid5: relieve lock contention in 
get_active_stripe()")
      __find_stripe() is called under conf->hash_locks + hash.
      But handle_stripe_clean_event() calls remove_hash() under
      conf->device_lock.

      Under some cirscumstances the hash chain can be circuited,
      and we get an infinite loop with disabled interrupts and locked hash
      lock in __find_stripe(). This leads to hard lockup on multiple CPUs
      and following system crash.

      I was able to reproduce this behavior on raid6 over 6 ssd disks.
      The devices_handle_discard_safely option should be set to enable trim
      support. The following script was used:

      for i in `seq 1 32`; do
          dd if=/dev/zero of=large$i bs=10M count=100 &
      done

      neilb: original was against a 3.x kernel.  I forward-ported
        to 4.3-rc.  This verison is suitable for any kernel since

      rbd: require stable pages if message data CRCs are enabled

      rbd requires stable pages, as it performs a crc of the page data before
      they are send to the OSDs.

      But since kernel 3.9 (patch 1d1d1a767206fbe5d4c69493b7e6d2a8d08cc0a0
      "mm: only enforce stable page writes if the backing device requires
      it") it is not assumed anymore that block devices require stable pages.

      This patch sets the necessary flag to get stable pages back for rbd.

      In a ceph installation that provides multiple ext4 formatted rbd
      devices "bad crc" messages appeared regularly (ca 1 message every 1-2
      minutes on every OSD that provided the data for the rbd) in the
      OSD-logs before this patch. After this patch this messages are pretty
      much gone (only ca 1-2 / month / OSD).

      arm64/efi: move arm64 specific stub C code to libstub

      Now that we added special handling to the C files in libstub, move
      the one remaining arm64 specific EFI stub C file to libstub as
      well, so that it gets the same treatment. This should prevent future
      changes from resulting in binaries that may execute incorrectly in
      UEFI context.

      With efi-entry.S the only remaining EFI stub source file under
      arch/arm64, we can also simplify the Makefile logic somewhat.

      hwmon: (nct6775) Introduce separate temperature labels for NCT6792 and 
NCT6793

      NCT6792 and NCT6793 are mostly register compatible to NCT6791, but
      temperature sources are different and difficult to manage with a single
      temperature label array. Introduce separate temperature label arrays
      for those chips to reflect the differences.

      ====================
      pull request (net-next): ipsec-next 2015-10-30

      1) The flow cache is limited by the flow cache limit which
         depends on the number of cpus and the xfrm garbage collector
         threshold which is independent of the number of cpus. This
         leads to the fact that on systems with more than 16 cpus
         we hit the xfrm garbage collector limit and refuse new
         allocations, so new flows are dropped. On systems with 16
         or less cpus, we hit the flowcache limit. In this case, we
         shrink the flow cache instead of refusing new flows.

         We increase the xfrm garbage collector threshold to INT_MAX
         to get the same behaviour, independent of the number of cpus.

      2) Fix some unaligned accesses on sparc systems.
         From Sowmini Varadhan.

      3) Fix some header checks in _decode_session4. We may call
         pskb_may_pull with a negative value converted to unsigened
         int from pskb_may_pull. This can lead to incorrect policy
         lookups. We fix this by a check of the data pointer position
         before we call pskb_may_pull.

      4) Reload skb header pointers after calling pskb_may_pull
         in _decode_session4 as this may change the pointers into
         the packet.

      5) Add a missing statistic counter on inner mode errors.

      Please pull or let me know if there are problems.

      ====================
      NFC 4.4 pull request

      This is the NFC pull request for 4.4.

      It's a bit bigger than usual, the 3 main culprits being:

      - A new driver for Intel's Fields Peak NCI chipset. In order to
        support this chipset we had to export a few NCI routines and
        extend the driver NCI ops to not only support proprietary
        commands but also core ones.

      - Support for vendor commands for both STM drivers, st-nci
        and st21nfca. Those vendor commands allow to run factory tests
        through the NFC netlink interface.

      - New i2c and SPI support for the Marvell driver, together with
        firmware download support for this driver's core.

      Besides that we also have:

      - A few file renames in the STM drivers, to keep the naming
        consistent between drivers.

      - Some improvements and fixes on the NCI HCI layer, mostly to
        properly reach a secure element over a legacy HCI link.

      - A few fixes for the s3fwrn5 and trf7970a drivers.

      Document that IRQ_NONE should be returned when IRQ not actually handled

      Our IRQ storm detection works when an interrupt handler returns
      IRQ_NONE for thousands of consecutive interrupts in a second. It
      doesn't hurt to occasionally return IRQ_NONE when the interrupt is
      actually genuine.

      Drivers should only be returning IRQ_HANDLED if they have actually
      *done* something to stop an interrupt from happening â?? it doesn't just
      mean "this really *was* my device".

      switchdev: Make flood to CPU optional

      In certain use cases it is not always desirable for the switch device to
      flood traffic to CPU port. Instead, only certain packet types (e.g.
      STP, LACP) should be trapped to it.

      ====================
      drivers: xgene: Add support RGMII TX/RX delay configuration

      X-Gene RGMII ethernet controller has a RGMII bridge that performs the
      task of converting the RGMII signal {RX_CLK,RX_CTL, RX_DATA[3:0]} from
      PHY to GMII signal {RX_DV,RX_ER,RX_DATA[7:0]} and vice versa.  This
      RGMII bridge has a provision to internally delay the input RX_CLK and
      the output TX_CLK using configuration registers. This will help in
      maintain the CLK-CTL delay relationship in various operating
      conditions.

      This patch adds support RGMII TX/RX delay configuration.

      Add RGMII TX/RX delay configuration support. RGMII standard requires 2ns
      delay to help the RGMII bridge receiver to sample data correctly. If the
      default value does not provide proper centering of the data sample, the
      TX/RX delay parameters can be used to adjust accordingly.

      bridge: set is_local and is_static before fdb entry is added to the fdb 
hashtable

      Problem Description:
      We can add fdbs pointing to the bridge with NULL ->dst but that has a
      few race conditions because br_fdb_insert() is used which first creates
      the fdb and then, after the fdb has been published/linked, sets
      "is_local" to 1 and in that time frame if a packet arrives for that fdb
      it may see it as non-local and either do a NULL ptr dereference in
      br_forward() or attach the fdb to the port where it arrived, and later
      br_fdb_insert() will make it local thus getting a wrong fdb entry.
      Call chain br_handle_frame_finish() -> br_forward():
      But in br_handle_frame_finish() in order to call br_forward() the dst
      should not be local i.e. skb != NULL, whenever the dst is
      found to be local skb is set to NULL so we can't forward it,
      and here comes the problem since it's running only
      with RCU when forwarding packets it can see the entry before "is_local"
      is set to 1 and actually try to dereference NULL.
      The main issue is that if someone sends a packet to the switch while
      it's adding the entry which points to the bridge device, it may
      dereference NULL ptr. This is needed now after we can add fdbs
      pointing to the bridge.  This poses a problem for
      br_fdb_update() as well, while someone's adding a bridge fdb, but
      before it has is_local == 1, it might get moved to a port if it comes
      as a source mac and then it may get its "is_local" set to 1

      This patch changes fdb_create to take is_local and is_static as
      arguments to set these values in the fdb entry before it is added to the
      hash. Also adds null check for port in br_forward.

bridge device")

      tools build: Fix libiberty feature detection

      Any CFLAGS or LDFLAGS set by the user need to be passed to the feature
      build command.  This many include for example -I or -L to point to
      libraries and include files in custom paths.

      In most of the test-*.bin rules in build/feature/Makefile, we use the 
BUILD
      macro which always sends in CFLAGS and LDFLAGS.  The libiberty build line
      however doesn't use the BUILD macro and thus needs to send in CFLAGS and
      LDFLAGS explicitly.  Without this, when using custom CFLAGS/LDFLAGS, 
libiberty
      fails to be detected and the perf link fails with something like:

         LINK     perf
        libbfd.a(bfd.o): In function `bfd_errmsg':
        bfd.c:(.text+0x168): undefined reference to `xstrerror'

      perf tools: Compile scriptlets to BPF objects when passing '.c' to --event

      This patch provides infrastructure for passing source files to --event
      directly using:

       # perf record --event bpf-file.c command

      This patch does following works:

       1) Allow passing '.c' file to '--event'. parse_events_load_bpf() is
          expanded to allow caller tell it whether the passed file is source
          file or object.

       2) llvm__compile_bpf() is called to compile the '.c' file, the result
          is saved into memory. Use bpf_object__open_buffer() to load the
          in-memory object.

      Introduces a bpf-script-example.c so we can manually test it:

       # perf record --clang-opt "-DLINUX_VERSION_CODE=0x40200" --event 
./bpf-script-example.c sleep 1

      Note that '--clang-opt' must put before '--event'.

      Futher patches will merge it into a testcase so can be tested 
automatically.

      perf bpf: Attach eBPF filter to perf event

      This is the final patch which makes basic BPF filter work. After
      applying this patch, users are allowed to use BPF filter like:

       # perf record --event ./hello_world.o ls

      A bpf_fd field is appended to 'struct evsel', and setup during the
      callback function add_bpf_event() for each 'probe_trace_event'.

      PERF_EVENT_IOC_SET_BPF ioctl is used to attach eBPF program to a newly
      created perf event. The file descriptor of the eBPF program is passed to
      perf record using previous patches, and stored into evsel->bpf_fd.

      It is possible that different perf event are created for one kprobe
      events for different CPUs. In this case, when trying to call the ioctl,
      EEXIST will be return. This patch doesn't treat it as an error.

      Committer note:

      The bpf proggie used so far:

        __attribute__((section("fork=_do_fork"), used))
        int fork(void *ctx)
        {
          return 0;
        }

        char _license[] __attribute__((section("license"), used)) = "GPL";
        int _version __attribute__((section("version"), used)) = 0x40300;

      failed to produce any samples, even with forks happening and it being
      running in system wide mode.

      That is because now the filter is being associated, and the code above
      always returns zero, meaning that all forks will be probed but filtered
      away ;-/

      Change it to 'return 1;' instead and after that:

        # trace --no-syscalls --event /tmp/foo.o
           0.000 perf_bpf_probe:fork:(ffffffff8109be30))
           2.333 perf_bpf_probe:fork:(ffffffff8109be30))
           3.725 perf_bpf_probe:fork:(ffffffff8109be30))
           4.550 perf_bpf_probe:fork:(ffffffff8109be30))
        ^C#

      And it works with all tools, including 'perf trace'.

      perf script: Enable printing of branch stack

      This patch improves perf script by enabling printing of the
      branch stack via the 'brstack' and 'brstacksym' arguments to
      the field selection option -F. The option is off by default
      and operates only if the perf.data file has branch stack content.

      The branches are printed in to/from pairs. The most recent branch
      is printed first. The number of branch entries vary based on the
      underlying hardware and filtering used.

      The brstack prints FROM/TO addresses in raw hexadecimal format.
      The brstacksym prints FROM/TO addresses in symbolic form wherever
      possible.

       $ perf script -F ip,brstack
        5d3000 0x401aa0/0x5d2000/M/-/-/-/0 ...

       $ perf script -F ip,brstacksym
        4011e0 noploop+0x0/noploop+0x0/P/-/-/0

      The notation F/T/M/X/A/C describes the attributes of the branch.
      F=from, T=to, M/P=misprediction/prediction, X=TSX, A=TSX abort, C=cycles

      arm64: page-align sections for DEBUG_RODATA

      A kernel built with DEBUG_RO_DATA && !CONFIG_DEBUG_ALIGN_RODATA doesn't
      have .text aligned to a page boundary, though fixup_executable works at
      page-granularity thanks to its use of create_mapping. If .text is not
      page-aligned, the first page it exists in may be marked non-executable,
      leading to failures when an attempt is made to execute code in said
      page.

      This patch upgrades ALIGN_DEBUG_RO and ALIGN_DEBUG_RO_MIN to force page
      alignment for DEBUG_RO_DATA && !CONFIG_DEBUG_ALIGN_RODATA kernels,
      ensuring that all sections with specific RWX permission requirements are
      mapped with the correct permissions.

      arm64: Fix compat register mappings

      For reasons not entirely apparent, but now enshrined in history, the
      architectural mapping of AArch32 banked registers to AArch64 registers
      actually orders SP_<mode> and LR_<mode> backwards compared to the
      intuitive r13/r14 order, for all modes except FIQ.

      Fix the compat_<reg>_<mode> macros accordingly, in the hope of avoiding
      subtle bugs with KVM and AArch32 guests.

      arm64/efi: do not assume DRAM base is aligned to 2 MB

      The current arm64 Image relocation code in the UEFI stub assumes that
      the dram_base argument it receives is always a multiple of 2 MB. In
      reality, it is simply the lowest start address of all RAM entries in
      the UEFI memory map, which means it could be any multiple of 4 KB.

      Since the arm64 kernel Image needs to reside TEXT_OFFSET bytes beyond
      a 2 MB aligned base, or it will fail to boot, make sure we round dram_base
      to 2 MB before using it to calculate the relocation address.

      ipv6: protect mtu calculation of wrap-around and infinite loop by 
rounding issues

      Raw sockets with hdrincl enabled can insert ipv6 extension headers
      right into the data stream. In case we need to fragment those packets,
      we reparse the options header to find the place where we can insert
      the fragment header. If the extension headers exceed the link's MTU we
      actually cannot make progress in such a case.

      Instead of ending up in broken arithmetic or rounding towards 0 and
      entering an endless loop in ip6_fragment, just prevent those cases by
      aborting early and signal -EMSGSIZE to user space.

      This is the second version of the patch which doesn't use the
      overflow_usub function, which got reverted for now.

      the first one so far and this patch cover only it.

      QCA9377 inherits most of the stuff (e.g. fw interfaces)
      from QCA61x4 design, so the integration was pretty straightforward.

      ath10k: remove shadow copy of CE descriptors for source ring

      For the messages from host to target, shadow copy of CE descriptors
      are maintained in source ring. Before writing actual CE descriptor,
      first shadow copy is filled and then it is copied to CE address space.
      To optimize in download path and to reduce d-cache pressure, removing
      shadow copy of CE descriptors. This will also reduce driver memory
      consumption by 33KB during on device probing.

      ath10k: cleanup copy engine send completion

      The physical address necessary to unmap DMA ('bufferp') is stored
      in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id
      when handling send completion (htc ep id is stored in sk_buff control
      buffer). So the unused output arguments {bufferp, nbytesp and 
transfer_idp}
      are removed from CE send completion. This change is needed before removing
      the shadow copy of copy engine (CE) descriptors in follow up patch.

      ath10k: enable adaptive CCA

      European Union has made it mandatory that all devices working in 2.4 GHz
      has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
      beginnig this year. The standard basically speaks about interferences
      in 2.4Ghz band.
      For example, when 802.11 device detects interference, TX must be stopped
      as long as interference is present.

      Adaptive CCA is a feature, when enabled the device learns from the
      environment and configures CCA levels adaptively. This will improve
      detecting interferences and the device can stop trasmissions till the
      interference is present eventually leading to good performances in
      varying interference conditions.

      The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
      QCA988X.

      arm64: Increase the max granular size

      Increase the standard cacheline size to avoid having locks in the same
      cacheline.

      Cavium's ThunderX core implements cache lines of 128 byte size. With
      current granulare size of 64 bytes (L1_CACHE_SHIFT=6) two locks could
      share the same cache line leading a performance degradation.
      Increasing the size fixes that.

      Increasing the size has no negative impact to cache invalidation on
      systems with a smaller cache line. There is an impact on memory usage,
      but that's not too important for arm64 use cases.

      ssb: pick PCMCIA host code support from b43 driver

      ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO.
      Every ssb bus contains cores AKA devices.
      The main idea is to have ssb driver scan/initialize bus and register
      ready-to-use cores. This way ssb drivers can operate on a single core
      mostly ignoring underlaying details.

      For some reason PCMCIA support was split between ssb and b43. We got
      PCMCIA host device probing in b43, then bus scanning in ssb and then
      wireless core probing back in b43. The truth is it's very unlikely we
      will ever see PCMCIA ssb device with no 802.11 core but I still don't
      see any advantage of the current architecture.

      With proposed change we get the same functionality with a simpler
      architecture, less Kconfig symbols, one killed EXPORT and hopefully
      cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb
      specific code in ssb driver.

      This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We
      already use similar solution with b43_pci_bridge.c. I didn't use "b43"
      in name of this new file as in theory any driver can operate on wireless
      core.

      mwifiex: toggle carrier state in start_ap/stop_ap.

      In uap mode the carrier is not enabled until after the first STA joins.
      The carrier triggers the bridge to start its state machine, and if STP
      is enabled, it takes 4 seconds as it transitions from disabled to
      forwarding. During this time the bridge drops all traffic, and the EAPOL
      handshake times out after 3 seconds, preventing stations from joining.

      Follow the logic used in mac80211 and start the carrier in start_ap
      and disable it in stop_ap. This has a nice benefit of allowing the
      first station connection time to be reduced by up to 75% when STP is
      in use.

      wcn36xx: introduce per-channel ring buffer locks

      wcn36xx implements a ring buffer for transmitted frames for each
      (high and low priority) DMA channel.  The ring buffers are lockless:
      new frames are inserted at the head of the queue, while finished
      packets are reaped from the tail.

      Unfortunately, the list manipulations are missing any kind of barriers
      so are susceptible to various races: for example, a TX completion
      handler might read an updated desc->ctrl before the head has actually
      advanced, and then null out the ctl->skb pointer while it is still
      being used in the TX path.

      Simplify things here by adding a spin lock when traversing the ring.

      ath9k: fix phyerror codes

      Some of the ath9k_phyerr enums were wrong from the
      beginning (and even before). Most of the time the
      codes were used for counters to be displayed over
      debugfs, which made this a non-functional issue.

      Some (e.g. ATH9K_PHYERR_FALSE_RADAR_EXT) are used
      for radar detection and require the correct code
      to work as intended.

      This patch includes:
      a) fixes
        ATH9K_PHYERR_FALSE_RADAR_EXT:    24 => 36
        ATH9K_PHYERR_CCK_LENGTH_ILLEGAL: 32 => 28
        ATH9K_PHYERR_CCK_POWER_DROP:     33 => 29
        ATH9K_PHYERR_HT_CRC_ERROR:       34 => 32
        ATH9K_PHYERR_HT_LENGTH_ILLEGAL:  35 => 33
        ATH9K_PHYERR_HT_RATE_ILLEGAL:    36 => 34

      b) extensions
        ATH9K_PHYERR_CCK_BLOCKER = 24
        ATH9K_PHYERR_HT_ZLF      = 35
        ATH9K_PHYERR_GREEN_FIELD = 37

      Aside from the correction and completion made in
      the enum, the patch also extends the display of
      the related counters in the debugfs.

      airo: fix scan after SIOCSIWAP (airo_set_wap)

      SIOCSIWAP (airo_set_wap) affects scan: only the AP specified by
      SIOCSIWAP is present in scan results.

      This makes NetworkManager work for the first time but then unable to
      find any other APs.

      Clear APList before starting scan and set it back after scan completes
      to work-around the problem.

      usb: musb: omap2430: Fix regression caused by driver core change

      Commit ddef08dd00f5 ("Driver core: wakeup the parent device before trying
      probe") started automatically ensuring the parent device is enabled when
      the child gets probed.

      This however caused a regression for MUSB omap2430 interface as the
      runtime PM for the parent device needs the child initialized to access
      the MUSB hardware registers.

      Let's delay the enabling of PM runtime for the parent until the child
      has been properly initialized as suggested in an earlier patch by
      Grygorii Strashko <grygorii.strashko@xxxxxx>.

      In addition to delaying pm_runtime_enable, we now also need to make sure
      the parent is enabled during omap2430_musb_init. We also want to propagate
      an error from omap2430_runtime_resume if struct musb is not initialized.

      Note that we use pm_runtime_put_noidle here for both the child and parent
      to prevent an extra runtime_suspend/resume cycle.

      Let's also add some comments to avoid confusion between the
      two different devices.

      Revert "ARM64: unwind: Fix PC calculation"

      This reverts commit e306dfd06fcb44d21c80acb8e5a88d55f3d1cf63.

      With this patch applied, we were the only architecture making this sort
      of adjustment to the PC calculation in the unwinder. This causes
      problems for ftrace, where the PC values are matched against the
      contents of the stack frames in the callchain and fail to match any
      records after the address adjustment.

      Whilst there has been some effort to change ftrace to workaround this,
      those patches are not yet ready for mainline and, since we're the odd
      architecture in this regard, let's just step in line with other
      architectures (like arch/arm/) for now.

      arm64: kernel: fix tcr_el1.t0sz restore on systems with extended idmap

      Commit dd006da21646 ("arm64: mm: increase VA range of identity map")
      introduced a mechanism to extend the virtual memory map range
      to support arm64 systems with system RAM located at very high offset,
      where the identity mapping used to enable/disable the MMU requires
      additional translation levels to map the physical memory at an equal
      virtual offset.

      The kernel detects at boot time the tcr_el1.t0sz value required by the
      identity mapping and sets-up the tcr_el1.t0sz register field accordingly,
      any time the identity map is required in the kernel (ie when enabling the
      MMU).

      After enabling the MMU, in the cold boot path the kernel resets the
      tcr_el1.t0sz to its default value (ie the actual configuration value for
      the system virtual address space) so that after enabling the MMU the
      memory space translated by ttbr0_el1 is restored as expected.

      Commit dd006da21646 ("arm64: mm: increase VA range of identity map")
      also added code to set-up the tcr_el1.t0sz value when the kernel resumes
      from low-power states with the MMU off through cpu_resume() in order to
      effectively use the identity mapping to enable the MMU but failed to add
      the code required to restore the tcr_el1.t0sz to its default value, when
      the core returns to the kernel with the MMU enabled, so that the kernel
      might end up running with tcr_el1.t0sz value set-up for the identity
      mapping which can be lower than the value required by the actual virtual
      address space, resulting in an erroneous set-up.

      This patchs adds code in the resume path that restores the tcr_el1.t0sz
      default value upon core resume, mirroring this way the cold boot path
      behaviour therefore fixing the issue.

      perf bpf: Collect perf_evsel in BPF object files

      This patch creates a 'struct perf_evsel' for every probe in a BPF object
      file(s) and fills 'struct evlist' with them. The previously introduced
      dummy event is now removed. After this patch, the following command:

       # perf record --event filter.o ls

      Can trace on each of the probes defined in filter.o.

      The core of this patch is bpf__foreach_tev(), which calls a callback
      function for each 'struct probe_trace_event' event for a bpf program
      with each associated file descriptors. The add_bpf_event() callback
      creates evsels by calling parse_events_add_tracepoint().

      Since bpf-loader.c will not be built if libbpf is turned off, an empty
      bpf__foreach_tev() is defined in bpf-loader.h to avoid build errors.

      Committer notes:

      Before:

        # /tmp/oldperf record --event /tmp/foo.o -a usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.198 MB perf.data ]
        # perf evlist
        /tmp/foo.o
        # perf evlist -v
        /tmp/foo.o: type: 1, size: 112, config: 0x9, { sample_period,
        sample_freq }: 4000, sample_type: IP|TID|TIME|CPU|PERIOD, disabled: 1,
        inherit: 1, mmap: 1, comm: 1, freq: 1, task: 1, sample_id_all: 1,
        exclude_guest: 1, mmap2: 1, comm_exec: 1

      I.e. we create just the PERF_TYPE_SOFTWARE (type: 1),
      PERF_COUNT_SW_DUMMY(config 0x9) event, now, with this patch:

        # perf record --event /tmp/foo.o -a usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.210 MB perf.data ]
        # perf evlist -v
        perf_bpf_probe:fork: type: 2, size: 112, config: 0x6bd, { sample_period,
        sample_freq }: 1, sample_type: IP|TID|TIME|CPU|PERIOD|RAW, disabled: 1,
        inherit: 1, mmap: 1, comm: 1, task: 1, sample_id_all: 1, exclude_guest:
        1, mmap2: 1, comm_exec: 1
        #

      We now have a PERF_TYPE_SOFTWARE (type: 1), but the config states 0x6bd,
      which is how, after setting up the event via the kprobes interface, the
      'perf_bpf_probe:fork' event is accessible via the perf_event_open
      syscall. This is all transient, as soon as the 'perf record' session
      ends, these probes will go away.

      To see how it looks like, lets try doing a neverending session, one that
      expects a control+C to end:

        # perf record --event /tmp/foo.o -a

      So, with that in place, we can use 'perf probe' to see what is in place:

        # perf probe -l
          perf_bpf_probe:fork  (on _do_fork@acme/git/linux/kernel/fork.c)

      We also can use debugfs:

        [root@felicio ~]# cat /sys/kernel/debug/tracing/kprobe_events
        p:perf_bpf_probe/fork _text+638512

      Ok, now lets stop and see if we got some forks:

        [root@felicio linux]# perf record --event /tmp/foo.o -a
        ^C[ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.325 MB perf.data (111 samples) ]

        [root@felicio linux]# perf script
            sshd  1271 [003] 81797.507678: perf_bpf_probe:fork:

            sshd 18309 [000] 81797.524917: perf_bpf_probe:fork:

        <SNIP>

      Sure enough, we have 111 forks :-)

      Callchains seems to work as well:

        int _version __attribute__((section("version"), used)) = 0x40100;

      For a 4.3.0-rc6+ kernel, say, this happens and needs checking at event
      parsing time, to provide a better error report to the user:

        # perf record --event /tmp/foo.o sleep 1
        libbpf: load bpf program failed: Invalid argument
        libbpf: -- BEGIN DUMP LOG ---
        libbpf:

        libbpf: failed to load program 'fork=_do_fork'
        libbpf: failed to load object '/tmp/foo.o'
        event syntax error: '/tmp/foo.o'
                             \___ Invalid argument: Are you root and runing a 
CONFIG_BPF_SYSCALL kernel?

            -e, --event <event>   event selector. use 'perf list' to list 
available events

      If we instead make it match, i.e. use 0x40300 on this v4.3.0-rc6+
      kernel, the whole process goes thru:

        # perf record --event /tmp/foo.o -a usleep 1

      perf tools: Create probe points for BPF programs

      This patch introduces bpf__{un,}probe() functions to enable callers to
      create kprobe points based on section names a BPF program. It parses the
      section names in the program and creates corresponding 'struct
      perf_probe_event' structures. The parse_perf_probe_command() function is
      used to do the main parsing work. The resuling 'struct perf_probe_event'
      is stored into program private data for further using.

      By utilizing the new probing API, this patch creates probe points during
      event parsing.

      To ensure probe points be removed correctly, register an atexit hook so
      even perf quit through exit() bpf__clear() is still called, so probing
      points are cleared. Note that bpf_clear() should be registered before
      bpf__probe() is called, so failure of bpf__probe() can still trigger
      bpf__clear() to remove probe points which are already probed.

      strerror style error reporting scaffold is created by this patch.
      bpf__strerror_probe() is the first error reporting function in
      bpf-loader.c.

      Committer note:

      Trying it:

      To build a test eBPF object file:

      I am testing using a script I built from the 'perf test -v LLVM' output:

       ---

      First asking to put a probe in a function not present in the kernel
      (misses the initial _):

        $ perf record --event /tmp/foo.o sleep 1
        Probe point 'do_fork' not found.
        event syntax error: '/tmp/foo.o'
                             \___ You need to check probing points in BPF file

        (add -v to see detail)
        Run 'perf list' for a list of valid events

         Usage: perf record [<options>] [<command>]
            or: perf record [<options>] -- <command> [<options>]

            -e, --event <event>   event selector. use 'perf list' to list 
available events
        $

       ---

      Now, with "__attribute__((section("fork=_do_fork"), used)):

       $ grep _do_fork /proc/kallsyms
       ffffffff81099ab0 T _do_fork
       $ perf record --event /tmp/foo.o sleep 1
       Failed to open kprobe_events: Permission denied
       event syntax error: '/tmp/foo.o'
                            \___ Permission denied

       ---

      Cool, we need to provide some better hints, "kprobe_events" is too low
      level, one doesn't strictly need to know the precise details of how
      these things are put in place, so something that shows the command
      needed to fix the permissions would be more helpful.

      Lets try as root instead:

        # perf record --event /tmp/foo.o sleep 1
        Lowering default frequency rate to 1000.
        Please consider tweaking /proc/sys/kernel/perf_event_max_sample_rate.

      perf tools: Enable passing bpf object file to --event

      By introducing new rules in tools/perf/util/parse-events.[ly], this
      patch enables 'perf record --event bpf_file.o' to select events by an
      eBPF object file. It calls parse_events_load_bpf() to load that file,
      which uses bpf__prepare_load() and finally calls bpf_object__open() for
      the object files.

      After applying this patch, commands like:

       # perf record --event foo.o sleep

      become possible.

      However, at this point it is unable to link any useful things onto the
      evsel list because the creating of probe points and BPF program
      attaching have not been implemented.  Before real events are possible to
      be extracted, to avoid perf report error because of empty evsel list,
      this patch link a dummy evsel. The dummy event related code will be
      removed when probing and extracting code is ready.

      Commiter notes:

      Using it:

        $ ls -la foo.o
        ls: cannot access foo.o: No such file or directory

      perf tools: Make perf depend on libbpf

      By adding libbpf into perf's Makefile, this patch enables perf to build
      libbpf if libelf is found and neither NO_LIBELF nor NO_LIBBPF is set.

      The newly introduced code is similar to how libapi and libtraceevent
      are wired into Makefile.perf.

      MANIFEST is also updated for 'make perf-*-src-pkg'.

      Append make_no_libbpf to tools/perf/tests/make.

      The 'bpf' feature check is appended into default FEATURE_TESTS and
      FEATURE_DISPLAY, so perf will check the API version of bpf in
      /path/to/kernel/include/uapi/linux/bpf.h. Which should not fail except
      when we are trying to port this code to an old kernel.

      Error messages are also updated to notify users about the lack of BPF
      support in 'perf record' if libelf is missing or the BPF API check
      failed.

      tools/lib/bpf is added to TAG_FOLDERS to allow us to navigate libbpf
      files when working on perf using tools/perf/tags.

      perf symbols: Fix endless loop in dso__split_kallsyms_for_kcore

      Currently we split symbols based on the map comparison, but symbols are 
stored
      within dso objects and maps could point into same dso objects (kernel 
maps).

      Hence we could end up changing rbtree we are currently iterating and mess 
it
      up. It's easily reproduced on s390x by running:

        $ perf record -a -- sleep 3
        $ perf buildid-list -i perf.data --with-hits

      The fix is to compare dso objects instead.

      perf tools: Enable pre-event inherit setting by config terms

      This patch allows perf record setting event's attr.inherit bit by
      config terms like:

        # perf record -e cycles/no-inherit/ ...
        # perf record -e cycles/inherit/ ...

      So user can control inherit bit for each event separately.

      In following example, a.out fork()s in main then do some complex
      CPU intensive computations in both of its children.

      Basic result with and without inherit:

        # perf record -e cycles -e instructions ./a.out
        [ perf record: Woken up 9 times to write data ]
        [ perf record: Captured and wrote 2.205 MB perf.data (47920 samples) ]
        # perf report --stdio
        # ...
        # Samples: 23K of event 'cycles'
        # Event count (approx.): 23641752891
        ...
        # Samples: 24K of event 'instructions'
        # Event count (approx.): 30428312415

        # perf record -i -e cycles -e instructions ./a.out
        [ perf record: Woken up 5 times to write data ]
        [ perf record: Captured and wrote 1.111 MB perf.data (24019 samples) ]
        ...
        # Samples: 12K of event 'cycles'
        # Event count (approx.): 11699501775
        ...
        # Samples: 12K of event 'instructions'
        # Event count (approx.): 15058023559

      Cancel inherit for one event when globally enable:

        # perf record -e cycles/no-inherit/ -e instructions ./a.out
        [ perf record: Woken up 7 times to write data ]
        [ perf record: Captured and wrote 1.660 MB perf.data (36004 samples) ]
        ...
        # Samples: 12K of event 'cycles/no-inherit/'
        # Event count (approx.): 11895759282
       ...
        # Samples: 24K of event 'instructions'
        # Event count (approx.): 30668000441

      Enable inherit for one event when globally disable:

        # perf record -i -e cycles/inherit/ -e instructions ./a.out
        [ perf record: Woken up 7 times to write data ]
        [ perf record: Captured and wrote 1.654 MB perf.data (35868 samples) ]
        ...
        # Samples: 23K of event 'cycles/inherit/'
        # Event count (approx.): 23285400229
        ...
        # Samples: 11K of event 'instructions'
        # Event count (approx.): 14969050259

      Committer note:

      One can check if the bit was set, in addition to seeing the result in
      the perf.data file size as above by doing one of:

        # perf record -e cycles -e instructions -a usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.911 MB perf.data (63 samples) ]
        # perf evlist -v
        cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: 
IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, inherit: 1, mmap: 1, 
comm: 1, freq: 1, task: 1, sample_id_all: 1, exclude_guest: 1, mmap2: 1, 
comm_exec: 1
        instructions: size: 112, config: 0x1, { sample_period, sample_freq }: 
4000, sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, 
inherit: 1, freq: 1, sample_id_all: 1, exclude_guest: 1
        #

      So, the inherit bit was set in both, now, if we disable it globally using
      --no-inherit:

        # perf record --no-inherit -e cycles -e instructions -a usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.910 MB perf.data (56 samples) ]
        # perf evlist -v
        cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: 
IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, mmap: 1, comm: 1, 
freq: 1, task: 1, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1
        instructions: size: 112, config: 0x1, { sample_period, sample_freq }: 
4000, sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, 
freq: 1, sample_id_all: 1, exclude_guest: 1

      No inherit bit set, then disabling it and setting just on the cycles 
event:

        # perf record --no-inherit -e cycles/inherit/ -e instructions -a usleep 
1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.909 MB perf.data (48 samples) ]
        # perf evlist -v
        cycles/inherit/: size: 112, { sample_period, sample_freq }: 4000, 
sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, inherit: 
1, mmap: 1, comm: 1, freq: 1, task: 1, sample_id_all: 1, exclude_guest: 1, 
mmap2: 1, comm_exec: 1
        instructions: size: 112, config: 0x1, { sample_period, sample_freq }: 
4000, sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, 
freq: 1, sample_id_all: 1, exclude_guest: 1
        #

      We can see it as well in by using a more verbose level of debug messages 
in
      the tool that sets up the perf_event_attr, 'perf record' in this case:

        [root@zoo ~]# perf record -vv --no-inherit -e cycles/inherit/ -e

      ARC: mm: HIGHMEM: kmap API implementation

      Implement kmap* API for ARC.

      This enables
       - permanent kernel maps (pkmaps): :kmap() API
       - fixmap : kmap_atomic()

      We use a very simple/uniform approach for both (unlike some of the other
      arches). So fixmap doesn't use the customary compile time address stuff.
      The important semantic is sleep'ability (pkmap) vs. not (fixmap) which
      the API guarantees.

      Note that this patch only enables highmem for subsequent PAE40 support
      as there is no real highmem for ARC in pure 32-bit paradigm as explained
      below.

      ARC has 2:2 address split of the 32-bit address space with lower half
      being translated (virtual) while upper half unstranslated
      (0x8000_0000 to 0xFFFF_FFFF). kernel itself is linked at base of
      unstranslated space (i.e. 0x8000_0000 onwards), which is mapped to say
      DDR 0x0 by external Bus Glue logic (outside the core). So kernel can
      potentially access 1.75G worth of memory directly w/o need for highmem.
      (the top 256M is taken by uncached peripheral space from 0xF000_0000 to
      0xFFFF_FFFF)

      In PAE40, hardware can address memory beyond 4G (0x1_0000_0000) while
      the logical/virtual addresses remain 32-bits. Thus highmem is required
      for kernel proper to be able to access these pages for it's own purposes
      (user space is agnostic to this anyways).

      perf symbols: we can now read separate debug-info files based on a build 
ID

      Recent GDB (at least on a vanilla Debian box) looks for debug information 
in

        /usr/lib/debug/.build-id/nn/nnnnnnn

      where nn/nnnnnn is the build-id of the stripped ELF binary. This is
      documented here:

        https://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html

      This was not working in perf because we didn't read the build id until
      AFTER we searched for the separate debug information file. This patch
      reads the build ID and THEN does the search.

      fs/writeback, rcu: Don't use list_entry_rcu() for pointer offsetting in 
bdi_split_work_to_wbs()

      bdi_split_work_to_wbs() uses list_for_each_entry_rcu_continue()
      to walk @bdi->wb_list.  To set up the initial iteration
      condition, it uses list_entry_rcu() to calculate the entry
      pointer corresponding to the list head; however, this isn't an
      actual RCU dereference and using list_entry_rcu() for it ended
      up breaking a proposed list_entry_rcu() change because it was
      feeding an non-lvalue pointer into the macro.

      Don't use the RCU variant for simple pointer offsetting.  Use
      list_entry() instead.

      efi: Fix warning of int-to-pointer-cast on x86 32-bit builds

      Commit:

        0f96a99dab36 ("efi: Add "efi_fake_mem" boot option")

      introduced the following warning message:

        drivers/firmware/efi/fake_mem.c:186:20: warning: cast to pointer from 
integer of different size [-Wint-to-pointer-cast]

      new_memmap_phy was defined as a u64 value and cast to void*,
      causing a int-to-pointer-cast warning on x86 32-bit builds.
      However, since the void* type is inappropriate for a physical
      address, the definition of struct efi_memory_map::phys_map has
      been changed to phys_addr_t in the previous patch, and so the
      cast can be dropped entirely.

      This patch also changes the type of the "new_memmap_phy"
      variable from "u64" to "phys_addr_t" to align with the types of
      memblock_alloc() and struct efi_memory_map::phys_map.

      efi: Use correct type for struct efi_memory_map::phys_map

      We have been getting away with using a void* for the physical
      address of the UEFI memory map, since, even on 32-bit platforms
      with 64-bit physical addresses, no truncation takes place if the
      memory map has been allocated by the firmware (which only uses
      1:1 virtually addressable memory), which is usually the case.

      However, commit:

        0f96a99dab36 ("efi: Add "efi_fake_mem" boot option")

      adds code that clones and modifies the UEFI memory map, and the
      clone may live above 4 GB on 32-bit platforms.

      This means our use of void* for struct efi_memory_map::phys_map has
      graduated from 'incorrect but working' to 'incorrect and
      broken', and we need to fix it.

      So redefine struct efi_memory_map::phys_map as phys_addr_t, and
      get rid of a bunch of casts that are now unneeded.

      ARC: smp: Introduce smp hook @init_early_smp for Master core

      This adds a platform agnostic early SMP init hook which is called on
      Master core before calling setup_processor()

        setup_arch()
           smp_init_cpus()
               smp_ops.init_early_smp()
           ...
           setup_processor()

      How this helps:
       - Used for one time init of certain SMP centric IP blocks, before
         calling setup_processor() which probes various bits of core,
         possibly including this block

       - Currently platforms need to call this IP block init from their
         init routines, which doesn't make sense as this is specific to ARC
         core and not platform and otherwise requires copy/paste in all
         (and hence a possible point of failure)

      e.g. MCIP init is called from 2 platforms currently (axs10x and sim)
      which will go away once we have this.

      This change only adds the hooks but they are empty for now. Next commit
      will populate them and remove the explicit init calls from platforms.

      ARC: smp: irqchip: handle IPI as percpu irq like timer

      The reason this was not done so far was lack of genuine IPI_IRQ for
      ARC700, as we don't have a SMP version of core yet (which might change
      soon thx to EZChip). Nevertheles to increase the build coverage, we
      need to allow CONFIG_SMP for ARC700 and still be able to run it on a
      UP platform (nsim or AXS101) with a UP Device Tree (SMP-on-UP)

      The build itself requires some define for IPI_IRQ and even a dummy
      value is fine since that code won't run anyways.

      net/mlx4: Copy/set only sizeof struct mlx4_eqe bytes

      When doing memcpy/memset of EQEs, we should use sizeof struct
      mlx4_eqe as the base size and not caps.eqe_size which could be bigger.

      If caps.eqe_size is bigger than the struct mlx4_eqe then we corrupt
      data in the master context.

      When using a 64 byte stride, the memcpy copied over 63 bytes to the
      slave_eq structure.  This resulted in copying over the entire eqe of
      interest, including its ownership bit -- and also 31 bytes of garbage
      into the next WQE in the slave EQ -- which did NOT include the ownership
      bit (and therefore had no impact).

      However, once the stride is increased to 128, we are overwriting the
      ownership bits of *three* eqes in the slave_eq struct.  This results
      in an incorrect ownership bit for those eqes, which causes the eq to
      seem to be full. The issue therefore surfaced only once 128-byte EQEs
      started being used in SRIOV and (overarchitectures that have 128/256
      byte cache-lines such as PPC) - e.g after commit 77507aa249ae
      "net/mlx4_core: Enable CQE/EQE stride support".

      seccomp, ptrace: add support for dumping seccomp filters

      This patch adds support for dumping a process' (classic BPF) seccomp
      filters via ptrace.

      PTRACE_SECCOMP_GET_FILTER allows the tracer to dump the user's classic BPF
      seccomp filters. addr should be an integer which represents the ith 
seccomp
      filter (0 is the most recently installed filter). data should be a struct
      sock_filter * with enough room for the ith filter, or NULL, in which case
      the filter is not saved. The return value for this command is the number 
of
      BPF instructions the program represents, or negative in the case of 
errors.
      Command specific errors are ENOENT: which indicates that there is no ith
      filter in this seccomp tree, and EMEDIUMTYPE, which indicates that the ith
      filter was not installed as a classic BPF filter.

      A caveat with this approach is that there is no way to get explicitly at
      the heirarchy of seccomp filters, and users need to memcmp() filters to
      decide which are inherited. This means that a task which installs two of
      the same filter can potentially confuse users of this interface.

      v2: * make save_orig const
          * check that the orig_prog exists (not necessary right now, but when
             grows eBPF support it will be)
          * s/n/filter_off and make it an unsigned long to match ptrace
          * count "down" the tree instead of "up" when passing a filter offset

      v3: * don't take the current task's lock for inspecting its seccomp mode
          * use a 0x42** constant for the ptrace command value

      v4: * don't copy to userspace while holding spinlocks

      v5: * add another condition to WARN_ON

      v6: * rebase on net-next

      ====================
      mpls: mulipath improvements

      Two improvements to the recently added mpls multipath support. The
      first is a fix for missing initialisation the nexthop address length
      for the v4 and v6 explicit null label routes, and the second is to
      reduce the amount of memory used by mpls routes by changing the way
      the via addresses are stored.

      mpls: reduce memory usage of routes

      Nexthops for MPLS routes have a via address field sized for the
      largest via address that is expected, which is 32 bytes. This means
      that in the most common case of having ipv4 via addresses, 28 bytes of
      memory more than required are used per nexthop. In the other common
      case of an ipv6 nexthop then 16 bytes more than required are
      used. With large numbers of MPLS routes this extra memory usage could
      start to become significant.

      To avoid allocating memory for a maximum length via address when not
      all of it is required and to allow for ease of iterating over
      nexthops, then the via addresses are changed to be stored in the same
      memory block as the route and nexthops, but in an array after the end
      of the array of nexthops. New accessors are provided to retrieve a
      pointer to the via address.

      To allow for O(1) access without having to store a pointer or offset
      per nh, the via address for each nexthop is sized according to the
      maximum via address for any nexthop in the route, which is stored in a
      new route field, rt_max_alen, but this is in an existing hole in
      struct mpls_route so it doesn't increase the size of the
      structure. Each via address is ensured to be aligned to VIA_ALEN_ALIGN
      to account for architectures that don't allow unaligned accesses.

      amd-xgbe: Fix race between access of desc and desc index

      During Tx cleanup it's still possible for the descriptor data to be
      read ahead of the descriptor index. A memory barrier is required between
      the read of the descriptor index and the start of the Tx cleanup loop.
      This allows a change to a lighter-weight barrier in the Tx transmit
      routine just before updating the current descriptor index.

      Since the memory barrier does result in extra overhead on arm64, keep
      the previous change to not chase the current descriptor value. This
      prevents the execution of the barrier for each loop performed.

      RDS-TCP: Recover correctly from pskb_pull()/pksb_trim() failure in 
rds_tcp_data_recv

      Either of pskb_pull() or pskb_trim() may fail under low memory conditions.
      If rds_tcp_data_recv() ignores such failures, the application will
      receive corrupted data because the skb has not been correctly
      carved to the RDS datagram size.

      Avoid this by handling pskb_pull/pskb_trim failure in the same
      manner as the skb_clone failure: bail out of rds_tcp_data_recv(), and
      retry via the deferred call to rds_send_worker() that gets set up on

      sock: don't enable netstamp for af_unix sockets

      netstamp_needed is toggled for all socket families if they request
      timestamping. But some protocols don't need the lower-layer timestamping
      code at all. This patch starts disabling it for af-unix.

      E.g. systemd enables timestamping during boot-up on the journald af-unix
      sockets, thus causing the system to globally enable timestamping in the
      lower networking stack. Still, it is very probable that timestamping
      gets activated, by e.g. dhclient or various NTP implementations.

      ====================
      Add new drivers: qed & qede

      This series implements the driver set for Qlogic's new QL4xxx series.
      These are 10/20/25/40/50/100 Gig capable converged nics, supporting
      ethernet (obviously), iscsi, fcoe, roce and iwarp protocols.

      The overall driver design includes a common module ('qed') and protocol
      specific dependent modules for ethernet ('qede'), fcoe ('qedf'),
      iscsi ('qedi') and roce ('qedr').
      The common module contains all of the common logic, e.g. initialization,
      cleanup, infrastructure for interrupt handling, link management, slowpath
      etc. as well as protocol agnostic features, and supplying an abstraction
      layer for other modules.
      The protocol specific modules can be compiled and operated independently
      of each other, with the exception of the rdma modules which are dependent
      on the ethernet module, in accordance with the kernel rdma stack design.

      This series only adds the core and ethernet modules, with basic L2
      capabilities. Future series will add the rest of the modules and enhance
      the L2 functionality.

      Ths patch series is constructed of the following patches:
      qed:  Add module with basic common support
      qed:  Add basic L2 interface
      qede: Add basic Network driver
      qed:  Add slowpath L2 support

      qed:  Add link support
      qede: Add support for link
      qed:  Add statistics support

      Changes from previos version:
      -----------------------------

      From Version 7:
        - Various small fixes according to Dave's suggestions; Largest change
          [code-wise] - don't use tabs for indenting function arguments.

      From Version 6:
        - Reduced the number of arguments for functions with exceptionally
          high number of parameters.

      From Version 5:
        - Style change and fixes [mostly in 1, 4 and 7].
          Thanks go to Francois Romieu, a mere mortal. ;-)

      From Version 4:
        - Drop dependency for x86_64.

      From Version 3:
        - Limit support of initial submission to x86_64.
        - Fix endian problems appearing via sparse [although no BE support yet].
        - Fix small issues suggested by the kbuild test robot.

      From Version 2:
        - Removed U64_{HI,LO}; Using {upper,lower}_32_bits instead.
        - Use regular napi weight definition.
        - [We still use the __le variants for variables, since we didn't get
           a reply regarding the change into non-user API types].

      From Version 1:
        - Removed private license file; Instead revised comments at source 
headers.

      qed: Add module with basic common support

      The Qlogic Everest Driver is the backend module for the QL4xxx ethernet
      products by Qlogic.

      This module serves two main purposes:
       1. It's responsible to contain all the common code that will be shared
          between the various drivers that would be used with said line of
          products. Flows such as chip initialization and de-initialization
          fall under this category.

       2. It would abstract the protocol-specific HW & FW components, allowing
          the protocol drivers to have a clean APIs which is detached in its
          slowpath configuration from the actual HSI.

      This adds a very basic module without any protocol-specific bits.
      I.e., this adds a basic implementation that almost entirely falls under
      the first category.

      openvswitch: Fix skb leak using IPv6 defrag

      nf_ct_frag6_gather() makes a clone of each skb passed to it, and if the
      reassembly is successful, expects the caller to free all of the original
      skbs using nf_ct_frag6_consume_orig(). This call was previously missing,
      meaning that the original fragments were never freed (with the exception
      of the last fragment to arrive).

      Fix this by ensuring that all original fragments except for the last
      fragment are freed via nf_ct_frag6_consume_orig(). The last fragment
      will be morphed into the head, so it must not be freed yet. Furthermore,
      retain the ->next pointer for the head after skb_morph().

      openvswitch: Fix double-free on ip_defrag() errors

      If ip_defrag() returns an error other than -EINPROGRESS, then the skb is
      freed. When handle_fragments() passes this back up to
      do_execute_actions(), it will be freed again. Prevent this double free
      by never freeing the skb in do_execute_actions() for errors returned by
      ovs_ct_execute. Always free it in ovs_ct_execute() error paths instead.

      fib_trie: leaf_walk_rcu should not compute key if key is less than pn->key

      We were computing the child index in cases where the key value we were
      looking for was actually less than the base key of the tnode.  As a result
      we were getting incorrect index values that would cause us to skip over
      some children.

      To fix this I have added a test that will force us to use child index 0 if
      the key we are looking for is less than the key of the current tnode.

      block: re-add discard_granularity and alignment checks

      In commit b49a087("block: remove split code in
      blkdev_issue_{discard,write_same}"), discard_granularity and alignment
      checks were removed. Ideally, with bio late splitting, the upper layers
      shouldn't need to depend on device's limits.

      Christoph reported a discard regression on the HGST Ultrastar SN100 NVMe
      device when mkfs.xfs. We have not found the root cause yet.

      This patch re-adds discard_granularity and alignment checks by reverting
      the related changes in commit b49a087. The good thing is now we can
      remove the 2G discard size cap and just use UINT_MAX to avoid bi_size
      overflow.

      Reserved for ACPI actually means that in such case the GPIO hardware will
      not update the interrupt status register (GPI_IS) even if the pin is

      does not trigger an interrupt.

      Allow using such pins as GPIOs, only prevent their usage as interrupts.

      We also rename function intel_pad_reserved_for_acpi() to be
      intel_pad_acpi_mode() which reflects the actual meaning better.

      pinctrl: intel: Add support for multiple GPIO chips sharing the interrupt

      On Intel Broxton the GPIO hardware consists of several chips that all 
share
      the parent interrupt. It is not possible to handle this by setting chained
      handler for each chip (as they will overwrite each other).

      To overcome this we need to request the interrupt using devm_request_irq()
      and pass IRQF_SHARED with the flags.

      gpio: generic: Revert to old error handling in bgpio_map

      Returning an error instead of NULL in bgpio_map if
      platform_get_resource_byname does not find a resource was introduced with
      commit cf3f2a2c8bae ("gpio: generic: improve error handling in 
bgpio_map").
      This results in several qemu runtime failures with default and non-default
      configurations, if attempts are made to boot from mmcblk0. Examples for
      failures with multi_v7_defconfig are

      Machine: vexpress-a9      dtb: vexpress-v2p-ca9
      Machine: vexpress-a15     dtb: vexpress-v2p-ca15-tc1

      Crash:

      VFS: Cannot open root device "mmcblk0" or unknown-block(0,0): error -6
      Please append a correct "root=" boot option; here are the available 
partitions:
      Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(0,0)

      Looking into the code, always returning an error if bgpio_map fails
      does not appear to make much sense, since the code in bgpio_setup_io
      specifically supports some of the resources to be NULL.

      drivers/pinctrl: Add the concept of an "init" state

      For pinctrl the "default" state is applied to pins before the driver's
      probe function is called.  This is normally a sensible thing to do,
      but in some cases can cause problems.  That's because the pins will
      change state before the driver is given a chance to program how those
      pins should behave.

      As an example you might have a regulator that is controlled by a PWM
      (output high = high voltage, output low = low voltage).  The firmware
      might leave this pin as driven high.  If we allow the driver core to
      reconfigure this pin as a PWM pin before the PWM's probe function runs
      then you might end up running at too low of a voltage while we probe.

      Let's introudce a new "init" state.  If this is defined we'll set
      pinctrl to this state before probe and then "default" after probe
      (unless the driver explicitly changed states already).

      An alternative idea that was thought of was to use the pre-existing
      "sleep" or "idle" states and add a boolean property that we should
      start in that mode.  This was not done because the "init" state is
      needed for correctness and those other states are only present (and
      only transitioned in to and out of) when (optional) power management
      is enabled.

      Changes in v3:
      - Moved declarations to pinctrl/devinfo.h
      - Fixed author/SoB

      Changes in v2:
      - Added comment to pinctrl_init_done() as per Linus W.

      mmc: pwrseq: Use highest priority for eMMC restart handler

      The pwrseq_emmc driver does a eMMC card reset before a system reboot to
      allow broken or limited ROM boot-loaders (that don't have an eMMC reset
      logic) to be able to read the second stage from the eMMC.

      But this has to be called before a system reboot handler and while most
      of them use the priority 128, there are other restart handlers (such as
      the syscon-reboot one) that use a higher priority. So, use the highest
      priority to make sure that the eMMC hw is reset before a system reboot.

      pinctrl: uniphier: set input-enable before pin-muxing

      While IECTRL is disabled, input signals are pulled-down internally.
      If pin-muxing is set up first, glitch signals (Low to High transition)
      might be input to hardware blocks.

      Bad case scenario:
      [1] The hardware block is already running before pinctrl is handled.
         (the reset is de-asserted by default or by a firmware, for example)
      [2] The pin-muxing is set up.  The input signals to hardware block
          are pulled-down by the chip-internal biasing.
      [3] The pins are input-enabled.  The signals from the board reach the
          hardware block.

      Actually, one invalid character is input to the UART blocks for such
      SoCs as PH1-LD4, PH1-sLD8, where UART devices start to run at the
      power on reset.

      To avoid such problems, pins should be input-enabled before muxing.

      s390_handle_damage() has character string parameter which was used as

      and therefore it would be rather easy to tell what went wrong.

      However gcc optimizes the strings away since a long time. And even if
      it wouldn't it is necessary to have a close look at the machine check
      interruption code to tell what's wrong.

      So remove the pointless error strings.

      s390: get rid of __set_psw_mask()

      With the removal of 31 bit code we can always assume that the epsw
      instruction is available. Therefore use the __extract_psw() function
      to disable and enable machine checks.

      blkcg: fix incorrect read/write sync/async stat accounting

      While unifying how blkcg stats are collected, 77ea733884eb ("blkcg:
      move io_service_bytes and io_serviced stats into blkcg_gq")
      incorrectly used bio->flags instead of bio->rw to tell the IO type.
      This made IOs to be accounted as the wrong type.  Fix it.

      scsi_dh: don't try to load a device handler during async probing

      Request_module gets really unhappy when called from async probing, so
      revert to not auto load device handler modules during the SCSI bus
      scan.  While autoloading would be really useful we never did this
      until 4.3-rc and it turns out that functionality doesn't actually
      work.

      ====================
      This series includes code simplifaction. The main changes are the correct
      xceiver handling (enable/disable) of the com20020 cards. The driver now 
handles
      link status change detection. The EAE PCI-ARCNET cards now make use of the

      - HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF
        configuration changes without CLF power off.
      - HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example
        the white list).
      - HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF
        technology. When using this command to anti-collision is done.

      In order to align with st21nfca, dts configuration properties
      ese_present and uicc_present are made available in st-nci driver.

      So far, in early development firmware, because
      nci_nfcee_mode_set(DISABLE) was not supported we had to try to
      enable it during the secure element discovery phase.

      After several trials on commercial and qualified firmware it appears
      that nci_nfcee_mode_set(ENABLE) and nci_nfcee_mode_set(DISABLE) are
      properly supported.

      Such feature also help us to eventually save some time (~5ms) when
      only one secure element is connected.

      The commit 1bab0de0274f ("dm-mpath, scsi_dh: don't let dm detach device

      As a result, handler data is freed immediately via scsi_dh->detach()
      in the context of scsi_remove_device() where activation request can be
      still in flight.

      This patch moves scsi_dh_handler_detach() to sdev releasing function,

      is already in quiesced state.

      net: dsa: bcm_sf2: Unhardcode port numbers

      While the current driver mostly supports BCM7445 which has a hardcoded
      location for its MoCA port on port 7 and port 0 for its internal PHY,
      this is not necessarily true for all other chips out there such as
      BCM3390 for instance.

      Walk the list of ports from Device Tree, get their port number ("reg"
      property), and then parse the "phy-mode" property and initialize two
      internal variables: moca_port and a bitmask of internal PHYs. Since we
      use interrupts for the MoCA port, we introduce two helper functions to
      enable/disable interrupts and do this at the appropriate bank (INTRL2_0
      or INTRL2_1).

      net: dsa: bcm_sf2: Implement FDB operations

      Add support for the FDB add, delete, and dump operations. The add and
      delete operations are implemented using directed ARL operations using
      the specified MAC address and consist in a read operation, write and
      readback operation.

      The dump operation consists in using the ARL search and software
      filtering entries which are not for the desired port.

      Input: alps - only the Dell Latitude D420/430/620/630 have separate stick 
button bits

      commit 92bac83dd79e ("Input: alps - non interleaved V2 dualpoint has
      separate stick button bits") assumes that all alps v2 non-interleaved
      dual point setups have the separate stick button bits.

      Later we limited this to Dell laptops only because of reports that this
      broke things on non Dell laptops. Now it turns out that this breaks things
      on the Dell Latitude D600 too. So it seems that only the Dell Latitude
      D420/430/620/630, which all share the same touchpad / stick combo,
      have these separate bits.

      This patch limits the checking of the separate bits to only these models
      fixing regressions with other models.

      x86/ioapic: Prevent NULL pointer dereference in setup_ioapic_dest()

      Commit 4857c91f0d19 changed the way how irq affinity is setup in
      setup_ioapic_dest() from using the core helper function to
      unconditionally calling the irq_set_affinity() callback of the
      underlying irq chip.

      That results in a NULL pointer dereference for the rare case where the
      underlying irq chip is lapic_chip which has no irq_set_affinity()
      callback. lapic_chip is occasionally used for the timer interrupt (irq
      0).

      The fix is simple: Check the availability of the callback instead of
      calling it unconditionally.

      Fixes: 4857c91f0d19 "x86/ioapic: Force affinity setting in 
setup_ioapic_dest()"

      memremap: fix highmem support

      Currently memremap checks if the range is "System RAM" and returns the
      kernel linear address.  This is broken for highmem platforms where a
      range may be "System RAM", but is not part of the kernel linear mapping.
      Fallback to ioremap_cache() in these cases, to let the arch code attempt
      to handle it.

      Note that ARM ioremap will WARN when attempting to remap ram, and in
      that case the caller needs to be fixed.  For this reason, existing
      ioremap_cache() usages for ARM are already trained to avoid attempts to
      remap ram.

      The impact of this bug is low for now since the pmem driver is the only
      user of memremap(), but this is important to fix before more conversions
      to memremap arrive in 4.4.

      error or help message - it should be OK since no UI is enabled at the

      mmc: dw_mmc-rockchip: MMC tuning with the clock phase framework

      This algorithm will try 1 degree increments, since there's no way to tell
      what resolution the underlying phase code uses. As an added bonus, doing
      many tunings yields better results since some tests are run more than once
      (ex: if the underlying driver uses 45 degree increments, the tuning code
      will try the same angle more than once).

      It will then construct a list of good phase ranges (even ranges that cross
      360/0), will pick the biggest range then it will set the sample_clk to the
      middle of that range.

      We do not touch ciu_drive (and by extension define default-drive-phase).
      Drive phase is mostly used to define minimum hold times, while one could
      write some code to determine what phase meets the minimum hold time (ex 10
      degrees) this will not work with the current clock phase framework (which
      floors angles, so we'll get 0 deg, and there's no way to know what
      resolution the floors happen at). We assume that the default drive angles
      set by the hardware are good enough.

      If a device has device specific code (like exynos) then that will still
      take precedence, otherwise this new code will execute. If the device wants
      to tune, but has no sample_clk defined we'll return EIO with an error
      message.

      mmc: dw_mmc: Use mmc_regulator_set_vqmmc in start_signal_voltage_switch

      We've introduced a new helper in the MMC core:
      mmc_regulator_set_vqmmc().  Let's use this in dw_mmc.  Using this new
      helper has some advantages:

      1. We get the mmc_regulator_set_vqmmc() behavior of trying to match
         VQMMC and VMMC when the signal voltage is 3.3V.  This ensures max
         compatibility.

      2. We get rid of a few more warnings when probing unsupported
         voltages.

      3. We get rid of some non-dw_mmc specific code in dw_mmc.

      mmc: core: Add mmc_regulator_set_vqmmc()

      This adds logic to the MMC core to set VQMMC.  This is expected to be
      called by MMC drivers like dw_mmc as part of (or instead of) their
      start_signal_voltage_switch() callback.

      A few notes:

      * When setting the signal voltage to 3.3V we do our best to make VQMMC
        and VMMC match.  It's been reported that this makes some old cards
        happy since they were tested back in the day before UHS when VQMMC
        and VMMC were provided by the same regulator.  A nice side effect of
        this is that we don't end up on the hairy edge of VQMMC (2.7V),
        which some EEs claim is a little too close to the minimum for
        comfort.
        This is done in two steps. At first we try to find a VQMMC within
        a 0.3V tolerance of VMMC and if this is not supported by the
        supplying regulator we try to find a suitable voltage within the
        whole 2.7V-3.6V area of the spec.

      * The two step approach is currently necessary, as the used
        regulator_set_voltage_triplet(min, target, max) uses a simple
        implementation that just tries two basic steps:
        regulator_set_voltage(target, max);
        regulator_set_voltage(min, target);
        So with only one step with 2.7-3.6V borders, if a suitable voltage
        is a bit below VMMC, we would directly get the lowest 2.7V
        which some boards (like Rockchips) don't like at all.

      * When setting the signal voltage to 1.8V or 1.2V we aim for that
        specific voltage instead of picking the lowest one in the range.

      * We very purposely don't print errors in mmc_regulator_set_vqmmc().
        There are cases where the MMC core will try several different
        voltages and we don't want to pollute the logs.

      mmc: core: Remove MMC_CLKGATE

      MMC_CLKGATE was once invented to save power by gating the bus clock at
      request inactivity. At that time it served its purpose. The modern way to
      deal with power saving for these scenarios, is by using runtime PM.

      Nowadays, several host drivers have deployed runtime PM, but for those
      that haven't and which still cares power saving at request inactivity,
      it's certainly time to deploy runtime PM as it has been around for several
      years now.

      To simplify code to mmc core and thus decrease maintenance efforts, this
      patch removes all code related to MMC_CLKGATE.

      clk: rockchip: Allow more precision for some mmc clock phases

      Because of the inexact nature of the extra MMC delay elements (it's
      not possible to keep the phase monotonic and to also make phases (mod
      90) > 70), we previously only allowed phases (mod 90) of 22.5, 45,
      and 67.5.

      But it's not the end of the world if the MMC clock phase goes
      non-monotonic.  At most we'll be 25 degrees off.  It's way better to
      test more phases to look for bad ones than to be 25 degrees off, because
      in the case of MMC really the point is to find bad phases and get as far
      asway from the as possible.  If we get to test extra phases by going
      slightly non-monotonic then that might be fine.  Worst case we would
      end up at a phases that's slight differnt than the one we wanted, but
      at least we'd still be quite far away from the a bad phase.

      mmc: sunxi: Add card busy detection

      Some sdio wifi modules have not been working reliable with the sunxi-mmc
      host code. This turns out to be caused by starting new io-rw commands 
while
      the card signals that it is still busy processing a previous command.

      This commit adds card-busy detection to the sunxi-mmc driver which 
together
      with recent core changes to check card-busy before starting io-rw commands
      fixes the wifi reliability issues on the Cubietruck and other sunxi boards
      using sdio wifi.

      mmc: block: Add new ioctl to send multi commands

      Certain eMMC devices allow vendor specific device information to be read
      via a sequence of vendor commands. These vendor commands must be issued
      in sequence and an atomic fashion. One way to support this would be to
      add an ioctl function for sending a sequence of commands to the device
      atomically as proposed here. These multi commands are simple array of
      the existing mmc_ioc_cmd structure.

      The structure passed via the ioctl uses a __u64 type to specify the number
      of commands (so that the structure is aligned on a 64-bit boundary) and a
      zero length array as a header for list of commands to be issued. The
      maximum number of commands that can be sent is determined by
      MMC_IOC_MAX_CMDS (which defaults to 255 and should be more than
      sufficient).

      If not, some irqs may be triggled and handled wrongly. Take
      the following into consideration, after request irq, if
      SDIO card interrupt enabled, a sd card in the sd slot will
      trigger a mass of interrupt(SDHCI_INT_CARD_INT), because at
      this time, the vmmc-regulator still not restore, no voltage
      supply for the sd card, so the pin of data0~data3 change and
      keep low, interrupt(SDHCI_INT_CARD_INT) will rise up ceaselessly.
      Due to we already reguest irq, system will be busy in handling
      this endless irq, can't response to other event.

      So we should call sdhci_init() before request irq in sd resume.

      arm: add missing of_node_put

      for_each_child_of_node performs an of_node_get on each iteration, so
      a break out of the loop requires an of_node_put.

      The of_node_put is duplicated in front of each error return, because the
      function contains a later error return that is beyond the end of the
      for_each_child_of_node and thus doesn't need of_node_put.

      The semantic patch that fixes this problem is as follows
      (http://coccinelle.lip6.fr):

      // <smpl>
      @@
      expression root,e;
      local idexpression child;

      (
         return child;

      The arcnet device has no interrupt to detect if the link has changed
      from disconnected to connected. This patch adds an timer to toggle the

      The SKB context buffer for HCI request is really not just for requests,
      information in their are preserved for the whole HCI layer. So it makes
      more sense to actually rename it into bt_cb()->hci and also call it then
      struct hci_ctrl.

      In addition that allows moving the decoded opcode for outgoing packets
      into that struct. So far it was just consuming valuable space from the
      main shared items. And opcode are not valid for L2CAP packets.

      x86/dma-mapping: Fix arch_dma_alloc_attrs() oops with NULL dev

      Commit 6894258eda2f broke drivers that pass NULL as the device pointer
      to dma_alloc. The reason is that arch_dma_alloc_attrs() now calls
      dma_alloc_coherent_gfp_flags() which in turn calls
      dma_alloc_coherent_mask(), where the device pointer is dereferenced
      unconditionally.

      Fix things by moving the ISA DMA fallback device assignment before the
      call to dma_alloc_coherent_gfp_flags().

      bnxt_en: Fix compile warnings when CONFIG_INET is not set.

      bnxt_gro_skb() has unused variables when CONFIG_INET is not set.  We
      really cannot support hardware GRO if CONFIG_INET is not set, so
      compile out bnxt_gro_skb() completely and define BNXT_FLAG_GRO to be 0
      if CONFIG_INET is not set.  This will effectively always disable
      hardware GRO if CONFIG_INET is not set.

      gianfar: Fix Rx BSY error handling

      The Rx BSY error interrupt indicates that a frame was
      received and discarded due to lack of buffers, so it's
      a rx ring overflow condition and has nothing to do with
      with bad rx packets.  Use the right counter.

      BSY conditions happen when the SoC is under performance
      stress.  Doing *more* work in stress situations by trying
      to schedule NAPI is not a good idea as the stressed system
      becomes still more stressed.  The Rx interrupt is already
      at work making sure the NAPI is scheduled.
      So calling gfar_receive() here does not help.  This issue
      was present since day 1.

      gianfar: Don't enable the Filer w/o the Parser

      Under one unusual circumstance it's possible to wrongly set
      FILREN without enabling PRSDEP as well in the RCTRL register,
      against the hardware specifications.  With the default config
      this does not happen because the default Rx offloads (Rx csum
      and Rx VLAN) properly enable PRSDEP.  But if anyone disables
      all these offloads (via ethtool), we get a wrong configuration
      were the Rx flow classification and hashing, and other Filer
      based features (e.g. wake-on-filer interrupt) won't work.
      This patch fixes the issue.
      Also, account for Rx FCB insertion which happens every time
      PRSDEP is set.

      irqchip/armada-370-xp: Fix regression by clearing IRQ_NOAUTOEN

      Commit d17cab4451df1 ("irqchip: Kill off set_irq_flags usage") changed
      the code of armada_370_xp_mpic_irq_map() from using set_irq_flags() to
      irq_set_probe().

      While the commit log seems to imply that there are no functional
      changes, there are indeed functional changes introduced by this
      commit: the IRQ_NOAUTOEN flag is no longer cleared. This functional
      change causes a regression on Armada XP, which no longer works
      properly after suspend/resume because per-CPU interrupts remain
      disabled.

      Due to how the hardware registers work, the irq-armada-370-xp cannot
      simply save/restore a bunch of registers at suspend/resume to make
      sure that the interrupts remain in the same state after
      resuming. Therefore, it relies on the kernel to say whether the
      interrupt is disabled or not, using the irqd_irq_disabled()
      function. This was all working fine while the IRQ_NOAUTOEN flag was
      cleared.

      With the change introduced by Rob Herring in d17cab4451df1, the
      IRQ_NOAUTOEN flag is now set for all interrupts. irqd_irq_disabled()
      returns false for per-CPU interrupts, and therefore our per-CPU
      interrupts are no longer re-enabled after resume.

      This commit works around this problem by clearing again the
      IRQ_NOAUTOEN flags, so that we are back to the situation we had before
      commit d17cab4451df1. This work around is proposed as a minimal fix
      for the problem, while a better long-term solution is being worked on.

      Bluetooth: Fix locking issue during fast SCO reconnection.

      When SCO connection is requested and disconnected fast, there is a change
      that sco_sock_shutdown is going to preempt thread started in 
sco_connect_cfm.
      When this happens struct sock sk may be removed but a pointer to it is 
still
      held in sco_conn_ready, where embedded spinlock is used. If it is used, 
but
      struct sock has been removed, it will crash.

      Block connection object, which will prevent struct sock from being removed
      and give connection process chance to finish.

      Bluetooth: Fix locking issue on SCO disconnection

      Thread handling SCO disconnection may get preempted in '__sco_sock_close'
      after dropping a reference to hci_conn but before marking this as NULL
      in associated struct sco_conn. When execution returs to this thread,
      this connection will possibly be released, resulting in kernel crash

      Lock connection before this point.

      Bluetooth: Fix crash on SCO disconnect

      When disconnecting audio from the phone's side, it may happen, that
      a thread handling HCI message 'disconnection complete' will get preempted
      in 'sco_conn_del' before calling 'sco_sock_kill', still holding a pointer
      to struct sock sk. Interrupting thread started in 'sco_sock_shutdown' will
      carry on releasing resources and will eventually release struct sock.
      When execution goes back to first thread it will call sco_sock_kill using
      now invalid pointer to already destroyed socket.

      Fix is to grab a reference to the socket a release it after calling
      'sco_sock_kill'.

      NFC: nci: Allow the driver to set handler for core nci ops

      The driver may be required to act when some responses or
      notifications arrive. For example the NCI core does not have a
      handler for NCI_OP_CORE_GET_CONFIG_RSP. The NFCC can send a
      config response that has to be read by the driver and the packet
      may contain vendor specific data.

      The Fields Peak driver needs to take certain actions when a reset
      notification arrives (packet also not handled by the nfc core).

      The driver handlers do not interfere with the core and they are
      called after the core processes the packet.

      x86/efi: Fix kernel panic when CONFIG_DEBUG_VIRTUAL is enabled

      When CONFIG_DEBUG_VIRTUAL is enabled, all accesses to __pa(address) are
      monitored to see whether address falls in direct mapping or kernel text
      mapping (see Documentation/x86/x86_64/mm.txt for details), if it does
      not, the kernel panics. During 1:1 mapping of EFI runtime services we 
access
      virtual addresses which are == physical addresses, thus the 1:1 mapping
      and these addresses do not fall in either of the above two regions and
      hence when passed as arguments to __pa() kernel panics as reported by
      Dave Hansen here https://lkml.kernel.org/r/5462999A.7090706@xxxxxxxxxx

      So, before calling __pa() virtual addresses should be validated which
      results in skipping call to split_page_count() and that should be fine
      because it is used to keep track of everything *but* 1:1 mappings.

      ====================
      tipc: improve broadcast implementation

      The TIPC broadcast link implementation is currently complex and hard to
      follow. It also incurs some amount of code and structure duplication,
      something that can be reduced significantly with a little effort.

      This commit series introduces a number of improvements which address
      both the locking structure, the code/structure duplication issue, and
      the overall readbility of the code.

      The series consists of three main parts:

      1-7: Adaptation to the new link structure, and preparation for the next
           step. In particular, we want the broadcast transmission link to
           have a life cycle that is longer than any of its potential (unicast
           and broadcast receive links) users. This eliminates the need to
           always test for the presence of this link before accessing it.

      8-10: This is what is really new in this series. Commit #9 is by far
            the largest and most important one, because it moves most of
            the broadcast functionality into link.c, partially reusing the
            fields and functionality of the unicast link. The removal of
            the "node_map" infrastructure in commit #10 is also an important
            achievement.

      11-16: Some improvements leveraging the changes made in the previous
             commits.

      The series needs commit 53387c4e22ac ("tipc: extend broadcast link window 
size")
      and commit e53567948f82 ("tipc: conditionally expand buffer headroom over 
udp tunnel")
      which are both present in 'net' but not yet in 'net-next', to apply 
cleanly.

      tipc: ensure binding table initial distribution is sent via first link

      Correct synchronization of the broadcast link at first contact between
      two nodes is dependent on the assumption that the binding table "bulk"
      update passes via the same link as the initial broadcast syncronization
      message, i.e., via the first link that is established.

      This is not guaranteed in the current implementation. If two link
      come up very close to each other in time, the "bulk" may quite well
      pass via the second link, and hence void the guarantee of a correct
      initial synchronization before the broadcast link is opened.

      This commit makes two small changes to strengthen this guarantee.

      1) We let the second established link occupy slot 1 of the
         "active_links" array, while the first link will retain slot 0.
         (This is in reality a cosmetic change, we could just as well keep
          the current, opposite order)

      2) We let the name distributor always use link selector/slot 0 when
         it sends it binding table updates.

      The extra traffic bias on the first link caused by this change should
      be negligible, since binding table updates constitutes a very small
      fraction of the total traffic.

      tipc: eliminate link's reference to owner node

      With the recent commit series, we have established a one-way dependency
      between the link aggregation (struct tipc_node) instances and their
      pertaining tipc_link instances. This has enabled quite significant code
      and structure simplifications.

      In this commit, we eliminate the field 'owner', which points to an
      instance of struct tipc_node, from struct tipc_link, and replace it with
      a pointer to struct net, which is the only external reference now needed
      by a link instance.

      tipc: eliminate redundant buffer cloning at transmission

      Since all packet transmitters (link, bcast, discovery) are now sending
      consumable buffer clones to the bearer layer, we can remove the
      redundant buffer cloning that is perfomed in the lower level functions
      tipc_l2_send_msg() and tipc_udp_send_msg().

      tipc: let neighbor discoverer tranmsit consumable buffers

      The neighbor discovery function currently uses the function
      tipc_bearer_send() for transmitting packets, assuming that the
      sent buffers are not consumed by the called function.

      We want to change this, in order to avoid unnecessary buffer cloning
      elswhere in the code.

      This commit introduces a new function tipc_bearer_skb() which consumes
      the sent buffers, and let the discoverer functions use this new call
      instead. The discoverer does now itself perform the cloning when
      that is necessary.

      tipc: simplify bearer level broadcast

      Until now, we have been keeping track of the exact set of broadcast
      destinations though the help structure tipc_node_map. This leads us to
      have to maintain a whole infrastructure for supporting this, including
      a pseudo-bearer and a number of functions to manipulate both the bearers
      and the node map correctly. Apart from the complexity, this approach is
      also limiting, as struct tipc_node_map only can support cluster local
      broadcast if we want to avoid it becoming excessively large. We want to
      eliminate this limitation, in order to enable introduction of scoped
      multicast in the future.

      A closer analysis reveals that it is unnecessary maintaining this "full
      set" overview; it is sufficient to keep a counter per bearer, indicating
      how many nodes can be reached via this bearer at the moment. The protocol
      is now robust enough to handle transitional discrepancies between the
      nominal number of reachable destinations, as expected by the broadcast
      protocol itself, and the number which is actually reachable at the
      moment. The initial broadcast synchronization, in conjunction with the
      retransmission mechanism, ensures that all packets will eventually be
      acknowledged by the correct set of destinations.

      This commit introduces these changes.

      tipc: let broadcast packet reception use new link receive function

      The code path for receiving broadcast packets is currently distinct
      from the unicast path. This leads to unnecessary code and data
      duplication, something that can be avoided with some effort.

      We now introduce separate per-peer tipc_link instances for handling
      broadcast packet reception. Each receive link keeps a pointer to the
      common, single, broadcast link instance, and can hence handle release
      and retransmission of send buffers as if they belonged to the own
      instance.

      Furthermore, we let each unicast link instance keep a reference to both
      the pertaining broadcast receive link, and to the common send link.
      This makes it possible for the unicast links to easily access data for
      broadcast link synchronization, as well as for carrying acknowledges for
      received broadcast packets.

      tipc: introduce capability bit for broadcast synchronization

      Until now, we have tried to support both the newer, dedicated broadcast
      synchronization mechanism along with the older, less safe, RESET_MSG/
      ACTIVATE_MSG based one. The latter method has turned out to be a hazard
      in a highly dynamic cluster, so we find it safer to disable it completely
      when we find that the former mechanism is supported by the peer node.

      For this purpose, we now introduce a new capabability bit,
      TIPC_BCAST_SYNCH, to inform any peer nodes that dedicated broadcast
      syncronization is supported by the present node. The new bit is conveyed
      between peers in the 'capabilities' field of neighbor discovery messages.

      tipc: make struct tipc_link generic to support broadcast

      Realizing that unicast is just a special case of broadcast, we also see
      that we can go in the other direction, i.e., that modest changes to the
      current unicast link can make it generic enough to support broadcast.

      The following changes are introduced here:

      - A new counter ("ackers") in struct tipc_link, to indicate how many
        peers need to ack a packet before it can be released.
      - A corresponding counter in the skb user area, to keep track of how
        many peers a are left to ack before a buffer can be released.
      - A new counter ("acked"), to keep persistent track of how far a peer
        has acked at the moment, i.e., where in the transmission queue to
        start updating buffers when the next ack arrives. This is to avoid
        double acknowledgements from a peer, with inadvertent relase of
        packets as a result.
      - A more generic tipc_link_retrans() function, where retransmit starts
        from a given sequence number, instead of the first packet in the
        transmision queue. This is to minimize the number of retransmitted
        packets on the broadcast media.

      When the new functionality is taken into use in the next commits,
      we expect it to have minimal effect on unicast mode performance.

      tipc: use explicit allocation of broadcast send link

      The broadcast link instance (struct tipc_link) used for sending is
      currently aggregated into struct tipc_bclink. This means that we cannot
      use the regular tipc_link_create() function for initiating the link, but
      do instead have to initiate numerous fields directly from the
      bcast_init() function.

      We want to reduce dependencies between the broadcast functionality
      and the inner workings of tipc_link. In this commit, we introduce
      a new function tipc_bclink_create() to link.c, and allocate the
      instance of the link separately using this function.

      tipc: make link implementation independent from struct tipc_bearer

      In reality, the link implementation is already independent from
      struct tipc_bearer, in that it doesn't store any reference to it.
      However, we still pass on a pointer to a bearer instance in the
      function tipc_link_create(), just to have it extract some
      initialization information from it.

      I later commits, we need to create instances of tipc_link without
      having any associated struct tipc_bearer. To facilitate this, we
      want to extract the initialization data already in the creator
      function in node.c, before calling tipc_link_create(), and pass
      this info on as individual parameters in the call.

      This commit introduces this change.

      tipc: create broadcast transmission link at namespace init

      The broadcast transmission link is currently instantiated when the
      network subsystem is started, i.e., on order from user space via netlink.

      This forces the broadcast transmission code to do unnecessary tests for
      the existence of the transmission link, as well in single mode node as
      in network mode.

      In this commit, we do instead create the link during initialization of
      the name space, and remove it when it is stopped. The fact that the
      transmission link now has a guaranteed longer life cycle than any of its
      potential clients paves the way for further code simplifcations
      and optimizations.

      tipc: move bcast definitions to bcast.c

      Currently, a number of structure and function definitions related
      to the broadcast functionality are unnecessarily exposed in the file
      bcast.h. This obscures the fact that the external interface towards
      the broadcast link in fact is very narrow, and causes unnecessary
      recompilations of other files when anything changes in those
      definitions.

      In this commit, we move as many of those definitions as is currently
      possible to the file bcast.c.

      We also rename the structure 'tipc_bclink' to 'tipc_bc_base', both
      since the name does not correctly describe the contents of this
      struct, and will do so even less in the future, and because we want
      to use the term 'link' more appropriately in the functionality
      introduced later in this series.

      Finally, we rename a couple of functions, such as tipc_bclink_xmit()
      and others that will be kept in the future, to include the term 'bcast'
      instead.

      There are no functional changes in this commit.

      md/raid10: fix the 'new' raid10 layout to work correctly.

      In Linux 3.9 we introduce a new 'far' layout for RAID10 which was
      supposed to rotate the replicas differently and so provide better
      resilience.  In particular it could survive more combinations of 2
      drive failures.

      Unfortunately. due to a coding error, this some did what was wanted,
      sometimes improved less than we hoped, and sometimes - in very
      unlikely circumstances - put multiple replicas on the same device so
      the redundancy was harmed.

      No public user-space tool has created arrays using this layout so it
      is very unlikely that zero-redundancy arrays actually exist.  Probably
      no arrays using any form of the new layout exist.  But we cannot be
      certain.

      So use another bit in the 'layout' number and introduce a bug-fixed
      version of the layout.
      Also when assembling an array, if it has a zero-redundancy layout,
      give a warning.

      md/raid10: don't clear bitmap bit when bad-block-list write fails.

      When a write fails and a bad-block-list is present, we can
      update the bad-block-list instead of writing the data.  If
      this succeeds then it is OK clear the relevant bitmap-bit as
      no further 'sync' of the block is needed.

      However if writing the bad-block-list fails then we need to
      treat the write as failed and particularly must not clear
      the bitmap bit.  Otherwise the device can be re-added (after
      any hardware connection issues are resolved) and because the
      relevant bit in the bitmap is clear, that block will not be
      resynced.  This leads to data corruption.

      We already delay the final bio_endio() on the write until
      the bad-block-list is written so that when the write
      returns: either that data is safe, the bad-block record is
      safe, or the fact that the device is faulty is safe.
      However we *don't* delay the clearing of the bitmap, so the
      bitmap bit can be recorded as cleared before we know if the
      bad-block-list was written safely.

      So: delay that until the write really is safe.
      i.e. move the call to close_write() until just before
      calling bio_endio(), and recheck the 'is array degraded'
      status before making that call.

      This bug goes back to v3.1 when bad-block-lists were
      introduced, though it only affects arrays created with
      mdadm-3.3 or later as only those have bad-block lists.

      Backports will require at least
      Commit: 95af587e95aa ("md/raid10: ensure device failure recorded before 
write request returns.")
      as well.  I'll send that to 'stable' separately.

      Note that of the two tests of R10BIO_WriteError that this
      patch adds, the first is certain to fail and the second is
      certain to succeed.  However doing it this way makes the
      patch more obviously correct.  I will tidy the code up in a
      future merge window.

      perf tools: Provide help for subset of options

      Some tools have a lot of options, so, providing a way to show help just
      for some of them may come handy:

        $ perf report -h --tui

         Usage: perf report [<options>]

              --tui             Use the TUI interface

        $ perf report -h --tui --showcpuutilization -b -c

         Usage: perf report [<options>]

          -b, --branch-stack    use branch records for per branch histogram 
filling
          -c, --comms <comm[,comm...]>
                                only consider symbols in these comms
              --showcpuutilization
                                Show sample percentage for different cpu modes
              --tui             Use the TUI interface

        $

      Using it with perf bash completion is also handy, just make sure you
      source the needed file:

        $ . ~/git/linux/tools/perf/perf-completion.sh

      Then press tab/tab after -- to see a list of options, put them after -h
      and only the options chosen will have its help presented:

        $ perf report -h --
        --asm-raw              --demangle-kernel      --group
        --kallsyms             --pretty               --stdio

       "It's late in the game, I know, but these fixes seemed important enough
        to warrant a late pull request.  They all involve oopses or use after
        frees or corruptions.

        Six serious fixes:

         - Hold the mutex around the find and corresponding update of our gid

         - The ifa list is rcu protected, copy its contents under rcu to avoid
           using a freed structure

         - On error, netdev might be null, so check it before trying to
           release it

         - On init, if workqueue alloc fails, fail init

         - The new demux patches exposed a bug in mlx5 and ipath drivers, we
           need to use the payload P_Key to determine the P_Key the packet
           arrived on because the hardware doesn't tell us the truth

         - Due to a couple convoluted error flows, it is possible for the CM
           to trigger a use_after_free and a double_free of rb nodes.  Add two
           checks to prevent that.  This code has worked for 10+ years.  It is
           likely that some of the recent changes have caused this issue to
           surface.  The current patch will protect us from nasty events for
           now while we track down why this is just now showing up"

      dm cache: the CLEAN_SHUTDOWN flag was not being set

      If the CLEAN_SHUTDOWN flag is not set when a cache is loaded then all 
cache
      blocks are marked as dirty and a full writeback occurs.

      __commit_transaction() is responsible for setting/clearing
      CLEAN_SHUTDOWN (based the flags_mutator that is passed in).

      Fix this issue, of the cache's on-disk flags being wrong, by making sure
      __commit_transaction() does not reset the flags after the mutator has
      altered the flags in preparation for them being serialized to disk.

      before:

      sb_flags = mutator(le32_to_cpu(disk_super->flags));
      disk_super->flags = cpu_to_le32(sb_flags);
      disk_super->flags = cpu_to_le32(cmd->flags);

      after:

      disk_super->flags = cpu_to_le32(cmd->flags);
      sb_flags = mutator(le32_to_cpu(disk_super->flags));
      disk_super->flags = cpu_to_le32(sb_flags);

      dm btree remove: fix a bug when rebalancing nodes after removal

      Commit 4c7e309340ff ("dm btree remove: fix bug in redistribute3") wasn't
      a complete fix for redistribute3().

      The redistribute3 function takes 3 btree nodes and shares out the entries
      evenly between them.  If the three nodes in total contained
      (MAX_ENTRIES * 3) - 1 entries between them then this was erroneously 
getting
      rebalanced as (MAX_ENTRIES - 1) on the left and right, and (MAX_ENTRIES + 
1) in
      the center.

      Fix this issue by being more careful about calculating the target number
      of entries for the left and right nodes.

      rbd: prevent kernel stack blow up on rbd map

      Mapping an image with a long parent chain (e.g. image foo, whose parent
      is bar, whose parent is baz, etc) currently leads to a kernel stack
      overflow, due to the following recursion in the reply path:

        rbd_osd_req_callback()
          rbd_obj_request_complete()
            rbd_img_obj_callback()
              rbd_img_parent_read_callback()
                rbd_obj_request_complete()
                  ...

      Limit the parent chain to 16 images, which is ~5K worth of stack.  When

      rbd: don't leak parent_spec in rbd_dev_probe_parent()

      Currently we leak parent_spec and trigger a "parent reference
      underflow" warning if rbd_dev_create() in rbd_dev_probe_parent() fails.
      The problem is we take the !parent out_err branch and that only drops
      refcounts; parent_spec that would've been freed had we called
      rbd_dev_unparent() remains and triggers rbd_warn() in
      rbd_dev_parent_put() - at that point we have parent_spec != NULL and
      parent_ref == 0, so counter ends up being -1 after the decrement.

      Redo rbd_dev_probe_parent() to fix this.

      Intel Wired LAN Driver Updates 2015-10-23

      This series contains updates to i40e, i40evf, if_link, ixgbe and ixgbevf.

      Anjali adds a workaround to drop any flow control frames from being
      transmitted from any VSI, so that a malicious VF cannot send flow control
      or PFC packets out on the wire.  Also fixed a bug in debugfs by grabbing
      the filter list lock before adding or deleting a filter.

      Akeem fixes an issue where we were unconditionally returning VEB bridge
      mode before allowing LB in the add VSI routine, resolve by checking if
      the bridge is actually in VEB mode first.

      Mitch fixed an issue where the incorrect structure was being used for
      VLAN filter list, which meant the VLAN filter list did not get
      processed correctly and VLAN filters would not be re-enabled after any
      kind of reset.

      Helin fixed a problem of possibly getting inconsistent flow control
      status after a PF reset.  The issue was requested_mode was being set
      with a default value during probe, but the hardware state could be a
      different value from this mode.

      Carolyn fixed a problem where the driver output of the OEM version
      string varied from the other tools.

      Jean Sacren fixes up kernel documentation by fixing function header
      comments to match actual variables used in the functions.  Also
      cleaned up variable initialization, when the variable would be
      over-written immediately.

      Hiroshi Shimanoto provides three patches to add "trusted" VF by adding
      netlink directives and an NDO entry.  Then implement these new controls
      in ixgbe and ixgbevf.  This series has gone through several iterations
      to address all the suggested community changes and concerns.

      mpls: flow-based multipath selection

      Change the selection of a multipath route to use a flow-based
      hash. This more suitable for traffic sensitive to reordering within a
      flow (e.g. TCP, L2VPN) and whilst still allowing a good distribution
      of traffic given enough flows.

      Selection of the path for a multipath route is done using a hash of:
      1. Label stack up to MAX_MP_SELECT_LABELS labels or up to and
         including entropy label, whichever is first.
      2. 3-tuple of (L3 src, L3 dst, proto) from IPv4/IPv6 header in MPLS
         payload, if present.

      Naturally, a 5-tuple hash using L4 information in addition would be
      possible and be better in some scenarios, but there is a tradeoff
      between looking deeper into the packet to achieve good distribution,
      and packet forwarding performance, and I have erred on the side of the
      latter as the default.

      mpls: multipath route support

      This patch adds support for MPLS multipath routes.

      Includes following changes to support multipath:
      - splits struct mpls_route into 'struct mpls_route + struct mpls_nh'

      - 'struct mpls_nh' represents a mpls nexthop label forwarding entry

      - moves mpls route and nexthop structures into internal.h

      - A mpls_route can point to multiple mpls_nh structs

      - the nexthops are maintained as a array (similar to ipv4 fib)

      - In the process of restructuring, this patch also consistently changes
        all labels to u8

      - Adds support to parse/fill RTA_MULTIPATH netlink attribute for
      multipath routes similar to ipv4/v6 fib

      - In this patch, the multipath route nexthop selection algorithm
      simply returns the first nexthop. It is replaced by a
      hash based algorithm from Robert Shearman in the next patch

      - mpls_route_update cleanup: remove 'dev' handling in mpls_route_update.
      mpls_route_update though implemented to update based on dev, it was
      never used that way. And the dev handling gets tricky with multiple
      nexthops. Cannot match against any single nexthops dev. So, this patch
      removes the unused 'dev' handling in mpls_route_update.

      - dead route/path handling will be implemented in a subsequent patch

      Example:

      $ip -f mpls route add 100 nexthop as 200 via inet 10.1.1.2 dev swp1 \
                      nexthop as 700 via inet 10.1.1.6 dev swp2 \
                      nexthop as 800 via inet 40.1.1.2 dev swp3

      $ip  -f mpls route show
      100
              nexthop as to 200 via inet 10.1.1.2  dev swp1
              nexthop as to 700 via inet 10.1.1.6  dev swp2

      Merge branch 'mdiobus_nested_read_write'

      Neil Armstrong says:

      ====================
      Refactor nested mdiobus read/write functions

      In order to avoid locked signal false positive for nested mdiobus
      read/write calls, nested code was introduced in mv88e6xxx and
      mdio-mux.
      But mv88e6060 also needs such nested mdiobus read/write calls.
      For sake of refactoring, introduce nested variants of mdiobus read/write
      and make them used by mv88e6xxx and mv88e6060.
      In a next patch, mdio-mux should also use these variant calls.

      ixgbe, ixgbevf: Add new mbox API xcast mode

      The limitation of the number of multicast address for VF is not enough
      for the large scale server with SR-IOV feature. IPv6 requires the 
multicast
      MAC address for each IP address to handle the Neighbor Solicitation
      message. We couldn't assign over 30 IPv6 addresses to a single VF.

      This patch introduces the new mailbox API, IXGBE_VF_UPDATE_XCAST_MODE,
      to update multicast mode of VF. This adds 3 modes;
        - NONE     only L2 exact match addresses or Flow Director enabled
        - MULTI    BAM and ROMPE set
        - ALLMULTI BAM, ROMPE and MPE set

      If a guest VF user wants over 30 MAC multicast addresses, set IFF_ALLMULTI
      to request PF to update xcast mode to enable VF multicast promiscuous 
mode.

      On the other hand, enabling VF multicast promiscuous mode may affect
      security and performance in the network of the NIC. Only trusted VF can
      enable multicast promiscuous mode. The behavior of untrusted VF is the
      same as previous version.

      tcp/dccp: fix hashdance race for passive sessions

      Multiple cpus can process duplicates of incoming ACK messages
      matching a SYN_RECV request socket. This is a rare event under
      normal operations, but definitely can happen.

      Only one must win the race, otherwise corruption would occur.

      To fix this without adding new atomic ops, we use logic in
      inet_ehash_nolisten() to detect the request was present in the same
      ehash bucket where we try to insert the new child.

      If request socket was not found, we have to undo the child creation.

      This actually removes a spin_lock()/spin_unlock() pair in
      reqsk_queue_unlink() for the fast path.

      Fixes: e994b2f0fb92 ("tcp: do not lock listener to process SYN packets")

      ppp: fix pppoe_dev deletion condition in pppoe_release()

      We can't rely on PPPOX_ZOMBIE to decide whether to clear po->pppoe_dev.
      PPPOX_ZOMBIE can be set by pppoe_disc_rcv() even when po->pppoe_dev is
      NULL. So we have no guarantee that (sk->sk_state & PPPOX_ZOMBIE) implies
      (po->pppoe_dev != NULL).
      Since we're releasing a PPPoE socket, we want to release the pppoe_dev
      if it exists and reset sk_state to PPPOX_DEAD, no matter the previous
      value of sk_state. So we can just check for po->pppoe_dev and avoid any
      assumption on sk->sk_state.

      amd-xgbe: Use wmb before updating current descriptor count

      The code currently uses the lightweight dma_wmb barrier before updating
      the current descriptor count. Under heavy load, the Tx cleanup routine
      was seeing the updated current descriptor count before the updated
      descriptor information. As a result, the Tx descriptor was being cleaned
      up before it was used because it was not "owned" by the hardware yet,
      resulting in a Tx queue hang.

      Using the wmb barrier insures that the descriptor is updated before the
      descriptor counter preventing the Tx queue hang. For extra insurance,
      the Tx cleanup routine is changed to grab the current decriptor count on
      entry and uses that initial value in the processing loop rather than
      trying to chase the current value.

      ipv4: implement support for NOPREFIXROUTE ifa flag for ipv4 address

      Currently adding a new ipv4 address always cause the creation of the
      related network route, with default metric. When a host has multiple
      interfaces on the same network, multiple routes with the same metric
      are created.

      If the userspace wants to set specific metric on each routes, i.e.
      giving better metric to ethernet links in respect to Wi-Fi ones,
      the network routes must be deleted and recreated, which is error-prone.

      This patch implements the support for IFA_F_NOPREFIXROUTE for ipv4
      address. When an address is added with such flag set, no associated
      network route is created, no network route is deleted when
      said IP is gone and it's up to the user space manage such route.

      overflow-arith: begin to add support for overflow builtins functions

      I add a new header, linux/overflow-arith.h, as the central place to add
      overflow and wrap-around checking functions. The reason I am doing so
      is that it can make use of compiler supported builtin functions which
      can leverage hardware.

      As I need this for a fix in the ipv6 stack, which is also included in
      this series, I propose to add it sooner than later over Davem's net
      tree. This is also the reason why I start slowly with only the one
      function I need at this time.

      ipv6: protect mtu calculation of wrap-around and infinite loop by 
rounding issues

      Raw sockets with hdrincl enabled can insert ipv6 extension headers
      right into the data stream. In case we need to fragment those packets,
      we reparse the options header to find the place where we can insert
      the fragment header. If the extension headers exceed the link's MTU we
      actually cannot make progress in such a case.

      Instead of ending up in broken arithmetic or rounding towards 0 and
      entering an endless loop in ip6_fragment, just prevent those cases by
      aborting early and signal -EMSGSIZE to user space.

      overflow-arith: begin to add support for overflow builtin functions

      The idea of the overflow-arith.h header is to collect overflow checking
      functions in one central place.

      If gcc compiler supports the __builtin_overflow_* builtins we use them
      because they might give better performance, otherwise the code falls
      back to normal overflow checking functions.

      The builtin_overflow functions are supported by gcc-5 and clang. The
      matter of supporting clang is to just provide a corresponding
      CC_HAVE_BUILTIN_OVERFLOW, because the specific overflow checking builtins
      don't differ between gcc and clang.

      I just provide overflow_usub function here as I intend this to get merged
      into net, more functions will definitely follow as they are needed.

      tcp: allow dctcp alpha to drop to zero

      If alpha is strictly reduced by alpha >> dctcp_shift_g and if alpha is 
less
      than 1 << dctcp_shift_g, then alpha may never reach zero. For example,
      given shift_g=4 and alpha=15, alpha >> dctcp_shift_g yields 0 and alpha
      remains 15. The effect isn't noticeable in this case below cwnd=137, but
      could gradually drive uncongested flows with leftover alpha down to
      cwnd=137. A larger dctcp_shift_g would have a greater effect.

      This change causes alpha=15 to drop to 0 instead of being decrementing by 
1
      as it would when alpha=16. However, it requires one less conditional to
      implement since it doesn't have to guard against subtracting 1 from 0U. A
      decay of 15 is not unreasonable since an equal or greater amount occurs at
      alpha >= 240.

      The error condition -EAGAIN, which is signaled by throw routes, tells
      the rules framework to walk on searching for next matches. If the walk
      ends and we stop walking the rules with the result of a throw route we

      lib/Kconfig.debug: disable -Wframe-larger-than warnings with KASAN=y

      When the kernel compiled with KASAN=y, GCC adds redzones for each
      variable on stack.  This enlarges function's stack frame and causes:

        'warning: the frame size of X bytes is larger than Y bytes'

      The worst case I've seen for now is following:

         ../net/wireless/nl80211.c: In function `nl80211_send_wiphy':
         ../net/wireless/nl80211.c:1731:1: warning: the frame size of 5448 
bytes is larger than 2048 bytes [-Wframe-larger-than=]

      That kind of warning becomes useless with KASAN=y.  It doesn't
      necessarily indicate that there is some problem in the code, thus we
      should turn it off.

      (The KASAN=y stack size in increased from 16k to 32k for this reason)

      mm: make sendfile(2) killable

      Currently a simple program below issues a sendfile(2) system call which
      takes about 62 days to complete in my test KVM instance.

              int fd;
              off_t off = 0;

              fd = open("file", O_RDWR | O_TRUNC | O_SYNC | O_CREAT, 0644);
              ftruncate(fd, 2);
              lseek(fd, 0, SEEK_END);
              sendfile(fd, fd, &off, 0xfffffff);

      Now you should not ask kernel to do a stupid stuff like copying 256MB in
      2-byte chunks and call fsync(2) after each chunk but if you do, sysadmin
      should have a way to stop you.

      We actually do have a check for fatal_signal_pending() in
      generic_perform_write() which triggers in this path however because we
      always succeed in writing something before the check is done, we return
      value > 0 from generic_perform_write() and thus the information about
      signal gets lost.

      Fix the problem by doing the signal check before writing anything.  That
      way generic_perform_write() returns -EINTR, the error gets propagated up
      and the sendfile loop terminates early.

      thp: use is_zero_pfn() only after pte_present() check

      Use is_zero_pfn() on pteval only after pte_present() check on pteval
      (It might be better idea to introduce is_zero_pte() which checks
      pte_present() first).

      Otherwise when working on a swap or migration entry and if pte_pfn's
      result is equal to zero_pfn by chance, we lose user's data in
      __collapse_huge_page_copy().  So if you're unlucky, the application
      segfaults and finally you could see below message on exit:

      kmod: don't run async usermode helper as a child of kworker thread

      call_usermodehelper_exec_sync() does fork() + wait() with "unignored"
      SIGCHLD.  What we have missed is that this worker thread can have other
      children previously forked by call_usermodehelper_exec_work() without
      UMH_WAIT_PROC.  If such a child exits in between it becomes a zombie
      because auto-reaping only works if SIGCHLD is ignored, and nobody can
      reap it (unless/until this worker thread exits too).

      Change the !UMH_WAIT_PROC case to use CLONE_PARENT.

      Note: this is only first step.  All PF_KTHREAD tasks, even created by
      kernel_thread() should have ->parent == kthreadd by default.

      xfrm4: Fix header checks in _decode_session4.

      We skip the header informations if the data pointer points
      already behind the header in question for some protocols.
      This is because we call pskb_may_pull with a negative value
      converted to unsigened int from pskb_may_pull in this case.
      Skipping the header informations can lead to incorrect policy
      lookups, so fix it by a check of the data pointer position
      before we call pskb_may_pull.

      xfrm: Fix unaligned access to stats in copy_to_user_state()

      On sparc, deleting established SAs (e.g., by restarting ipsec)
      results in unaligned access messages via xfrm_del_sa ->
      km_state_notify -> xfrm_send_state_notify().

      Even though struct xfrm_usersa_info is aligned on 8-byte boundaries,
      netlink attributes are fundamentally only 4 byte aligned, and this
      cannot be changed for nla_data() that is passed up to userspace.
      As a result, the put_unaligned() macro needs to be used to
      set up potentially unaligned fields such as the xfrm_stats in
      copy_to_user_state()

      Same ndo operation can be used for lwtunnel devices and compat
      ovs-tnl-vport devices. So after adding such device operation
      we can remove similar operation from ovs-vport.

      perf annotate: Don't die() when finding an invalid config option

      The perf_config() infrastructure we inherited from git calls die() when
      the provided config callback returns -1, meaning some key in a config
      section is unexpected, that seems ok for a stdio based tool, but in
      --tui we end up messing up the output, so just tell the user about the
      error, wait for a keystroke and return 0, being more resilient and
      proceeding with what we managed to parse.

      That die() needs to die, tho :-)

      perf annotate: Fix 'annotate.use_offset' config variable usage

      However commit 0c4a5bcea460 ("perf annotate: Display total number of
      samples with --show-total-period") added a new config item at the end.
      This resulted in the 'annotate.use_offset' config variable cannot be

      perf tools: Improve call graph documents and help messages

      The --call-graph option is complex so we should provide better guide for
      users.  Also change help message to be consistent with config option
      names.  Now perf top will show help like below:

        $ perf top --call-graph
          Error: option `call-graph' requires a value

         Usage: perf top [<options>]

            --call-graph 
<record_mode[,record_size],print_type,threshold[,print_limit],order,sort_key[,branch]>
                 setup and enables call-graph (stack chain/backtrace):

                record_mode:    call graph recording mode (fp|dwarf|lbr)
                record_size:    if record_mode is 'dwarf', max size of stack 
recording (<bytes>)
                                default: 8192 (bytes)
                print_type:     call graph printing style 
(graph|flat|fractal|none)
                threshold:      minimum call graph inclusion threshold 
(<percent>)
                print_limit:    maximum number of call graph entry (<number>)
                order:          call graph order (caller|callee)
                sort_key:       call graph sort key (function|address)
                branch:         include last branch info to call graph (branch)

      perf tools: Defaults to 'caller' callchain order only if --children is 
enabled

      The caller callchain order is useful with --children option since it can
      show 'overview' style output, but other commands which don't use
      --children feature like 'perf script' or even 'perf report/top' without
      --children are better to keep callee order.

      perf top: Support call-graph display options also

      Currently 'perf top --call-graph' option is same as 'perf record'.  But
      'perf top' also need to receive display options in 'perf report'.  To do
      that, change parse_callchain_report_opt() to allow record options too.

      Now perf top can receive display options like below:

        $ perf top --call-graph
          Error: option `call-graph' requires a value

         Usage: perf top [<options>]

              --call-graph

                     fractal, or none), min percent threshold, optional
                     print limit, callchain order, key (function or
                     address), add branches

      tools lib traceevent: Support %ps/%pS

      Commits such as 65dd297ac25565 ("xfs: %pF is only for function
      pointers") caused a regression because pretty_print() didn't support
      %ps/%pS.  The current %pf/%pF implementation in pretty_print() is what
      %ps/%pS is supposed to do, so use the same code for %ps/%pS.

      Addressing the incorrect %pf/%pF implementation is beyond the scope of
      this patch.

      Initialize it to 0 so that on success we return the value and no need to

      [drivers/media/platform/sti/c8sectpfe/c8sectpfe-core.c:1210]:
        (error) Uninitialized variable: ret

      ret is never initialised, so garbage is being returned. Instead
      return the error return from the call of request_firmware_nowait

      ARM: dts: fix gpio-keys wakeup-source property

      The keyboard driver for GPIO buttons(gpio-keys) checks for one of the
      two boolean properties to enable gpio buttons as wakeup source:
      1. "wakeup-source" or
      2. the legacy "gpio-key,wakeup"

      However juno, ste-snowball and emev2-kzm9d dts file have a undetected
      "wakeup" property to indictate the wakeup source.

      This patch fixes it by making use of "wakeup-source" property.

         We skip the header informations if the data pointer points

         This is because we call pskb_may_pull with a negative value
         converted to unsigened int from pskb_may_pull in this case.
         Skipping the header informations can lead to incorrect policy

      net: dsa: implement port_fdb_dump in drivers

      Not all switch chips provide a Get Next kind of operation to dump FDB 
entries.
      It is preferred to let the driver handle the dump operation the way it 
works
      best for the chip. Thus, drop port_fdb_getnext and implement the 
port_fdb_dump
      operation in DSA, which pushes the switchdev FDB dump callback down to the
      drivers. mv88e6xxx is the only driver affected and is updated accordingly.

      mISDN: fix OOM condition for sending queued I-Frames

      The old code did not check the return value of skb_clone().
      The extra skb_clone() is not needed at all, if using 
skb_realloc_headroom()
      instead, which gives us a private copy with enough headroom as well.
      We need to requeue the original skb if the call failed, because we cannot
      inform upper layers about the data loss. Restructure the code to minimise
      rollback effort if it happens.

      VSOCK: sock_put wasn't safe to call in interrupt context

      In the vsock vmci_transport driver, sock_put wasn't safe to call
      in interrupt context, since that may call the vsock destructor
      which in turn calls several functions that should only be called
      from process context. This change defers the callling of these
      functions  to a worker thread. All these functions were
      deallocation of resources related to the transport itself.

      Furthermore, an unused callback was removed to simplify the
      cleanup.

      Multiple customers have been hitting this issue when using
      VMware tools on vSphere 2015.

      Also added a version to the vmci transport module (starting from
      1.0.2.0-k since up until now it appears that this module was
      sharing version with vsock that is currently at 1.0.1.0-k).

      netlink: fix locking around NETLINK_LIST_MEMBERSHIPS

      Currently, NETLINK_LIST_MEMBERSHIPS grabs the netlink table while copying
      the membership state to user-space. However, grabing the netlink table is
      effectively a write_lock_irq(), and as such we should not be triggering
      page-faults in the critical section.

      This can be easily reproduced by the following snippet:
          int s = socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE);
          void *p = mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, 
-1, 0);
          int r = getsockopt(s, 0x10e, 9, p, (void*)((char*)p + 4092));

      This should work just fine, but currently triggers EFAULT and a possible
      WARN_ON below handle_mm_fault().

      Fix this by reducing locking of NETLINK_LIST_MEMBERSHIPS to a read-side
      lock. The write-lock was overkill in the first place, and the read-lock
      allows page-faults just fine.

      bpf_perf_event_output helper

      Over the last year there were multiple attempts to let eBPF programs
      output data into perf events by He Kuang and Wangnan.
      The last one was:
      https://lkml.org/lkml/2015/7/20/736
      It was almost perfect with exception that all bpf programs would sent
      data into one global perf_event.
      This patch set takes different approach by letting user space
      open independent PERF_COUNT_SW_BPF_OUTPUT events, so that program
      output won't collide.

      Wangnan is working on corresponding perf patches.

      bpf: introduce bpf_perf_event_output() helper

      This helper is used to send raw data from eBPF program into
      special PERF_TYPE_SOFTWARE/PERF_COUNT_SW_BPF_OUTPUT perf_event.
      User space needs to perf_event_open() it (either for one or all cpus) and
      store FD into perf_event_array (similar to bpf_perf_event_read() helper)
      before eBPF program can send data into it.

      Today the programs triggered by kprobe collect the data and either store
      it into the maps or print it via bpf_trace_printk() where latter is the 
debug
      facility and not suitable to stream the data. This new helper replaces
      such bpf_trace_printk() usage and allows programs to have dedicated
      channel into user space for post-processing of the raw data collected.

      ipvlan: read direct ifindex instead of iflink

      In the ipv4 outbound path of an ipvlan device in l3 mode, the ifindex is
      being grabbed from dev_get_iflink. This works for the physical device
      case, since as the documentation of that function notes: "Physical
      interfaces have the same 'ifindex' and 'iflink' values.".  However, if
      the master device is a veth, and the pairs are in separate net
      namespaces, the route lookup will fail with -ENODEV due to outer veth
      pair being in a separate namespace from the ipvlan master/routing
      namespace.

        ns0    |   ns1    |   ns2
       veth0a--|--veth0b--|--ipvl0

      In ipvlan_process_v4_outbound(), a packet sent from ipvl0 in the above
      configuration will pass fl.flowi4_oif == veth0a to
      ip_route_output_flow(), but *net == ns1.

      Notice also that ipv6 processing is not using iflink. Since there is a
      discrepancy in usage, fixup both v4 and v6 case to use local dev
      variable.

      Tested this with l3 ipvlan on top of veth, as well as with single
      physical interface in the top namespace.

      Commit 00d8689b85a7 ("i2c: mv64xxx: rework offload support to fix

      debugging-related "return false" at the beginning of the

      that offloading is in fact never used, which wasn't really the

      This commit fixes that problem by removing the bogus "return false".

      ieee802154: 6lowpan: fix memory leak

      Looking at current situation of memory management in 6lowpan receive
      function I detected some invalid handling. After calling
      lowpan_invoke_rx_handlers we will do a kfree_skb and then NET_RX_DROP on
      error handling. We don't do this before, also on
      skb_share_check/skb_unshare which might manipulate the reference
      counters.

      After running some 'grep -r "dev_add_pack" net/' to look how others
      packet-layer receive callbacks works I detected that every subsystem do
      a kfree_skb, then NET_RX_DROP without calling skb functions which
      might manipulate the skb reference counters. This is the reason why we
      should do the same here like all others subsystems. I didn't find any
      documentation how the packet-layer receive callbacks handle NET_RX_DROP
      return values either.

      This patch will add a kfree_skb, then NET_RX_DROP handling for the
      "trivial checks", in case of skb_share_check/skb_unshare the kfree_skb
      call will be done inside these functions.

      ipv6: gro: support sit protocol

      Tom Herbert added SIT support to GRO with commit
      19424e052fb4 ("sit: Add gro callbacks to sit_offload"),
      later reverted by Herbert Xu.

      The problem came because Tom patch was building GRO
      packets without proper meta data : If packets were locally
      delivered, we would not care.

      But if packets needed to be forwarded, GSO engine was not
      able to segment individual segments.

      With the following patch, we correctly set skb->encapsulation
      and inner network header. We also update gso_type.

      Tested:

      Server :
      netserver
      modprobe dummy
      ifconfig dummy0 8.0.0.1 netmask 255.255.255.0 up

      openvswitch: Serialize nested ct actions if provided

      If userspace provides a ct action with no nested mark or label, then the
      storage for these fields is zeroed. Later when actions are requested,
      such zeroed fields are serialized even though userspace didn't
      originally specify them. Fix the behaviour by ensuring that no action is
      serialized in this case, and reject actions where userspace attempts to
      set these fields with mask=0. This should make netlink marshalling
      consistent across deserialization/reserialization.

      netlink: Rightsize IFLA_AF_SPEC size calculation

      if_nlmsg_size() overestimates the minimum allocation size of netlink
      dump request (when called from rtnl_calcit()) or the size of the
      message (when called from rtnl_getlink()). This is because
      ext_filter_mask is not supported by rtnl_link_get_af_size() and
      rtnl_link_get_size().

      The over-estimation is significant when at least one netdev has many
      VLANs configured (8 bytes for each configured VLAN).

      This patch-set "rightsizes" the protocol specific attribute size
      calculation by propagating ext_filter_mask to rtnl_link_get_af_size()
      and adding this a argument to get_link_af_size op in rtnl_af_ops.

      Bridge module already used filtering aware sizing for notifications.
      br_get_link_af_size_filtered() is consistent with the modified
      get_link_af_size op so it replaces br_get_link_af_size() in br_af_ops.
      br_get_link_af_size() becomes unused and thus removed.

      tipc: conditionally expand buffer headroom over udp tunnel

      In commit d999297c3dbbe ("tipc: reduce locking scope during packet 
reception")
      we altered the packet retransmission function. Since then, when
      restransmitting packets, we create a clone of the original buffer
      using __pskb_copy(skb, MIN_H_SIZE), where MIN_H_SIZE is the size of
      the area we want to have copied, but also the smallest possible TIPC
      packet size. The value of MIN_H_SIZE is 24.

      Unfortunately, __pskb_copy() also has the effect that the headroom
      of the cloned buffer takes the size MIN_H_SIZE. This is too small
      for carrying the packet over the UDP tunnel bearer, which requires
      a minimum headroom of 28 bytes. A change to just use pskb_copy()
      lets the clone inherit the original headroom of 80 bytes, but also
      assumes that the copied data area is of at least that size, something
      that is not always the case. So that is not a viable solution.

      We now fix this by adding a check for sufficient headroom in the
      transmit function of udp_media.c, and expanding it when necessary.

      include subdirectories in the build, so it doesn't make sense to make it
      tristate.

      tipc: allow non-linear first fragment buffer

      The current code for message reassembly is erroneously assuming that
      the the first arriving fragment buffer always is linear, and then goes
      ahead resetting the fragment list of that buffer in anticipation of
      more arriving fragments.

      However, if the buffer already happens to be non-linear, we will
      inadvertently drop the already attached fragment list, and later
      on trig a BUG() in __pskb_pull_tail().

      We see this happen when running fragmented TIPC multicast across UDP,
      something made possible since
      commit d0f91938bede ("tipc: add ip/udp media type")

      We fix this by not resetting the fragment list when the buffer is non-
      linear, and by initiatlizing our private fragment list tail pointer to
      the tail of the existing fragment list.

      openvswitch: Allocate memory for ovs internal device stats.

      "openvswitch: Remove vport stats" removed the per-vport statistics, in
      order to use the netdev's statistics fields.
      "openvswitch: Fix ovs_vport_get_stats()" fixed the export of these stats
      to user-space, by using the provided netdev_ops to collate them - but ovs
      internal devices still use an unallocated dev->tstats field to count
      packets, which are no longer exported by this api.

      Allocate the dev->tstats field for ovs internal devices, and wire up
      ndo_get_stats64 with the original implementation of
      ovs_vport_get_stats().

      On its own, "openvswitch: Fix ovs_vport_get_stats()" fixes the OOPs,
      unmasking a full-on panic on arm64:

      tipc: extend broadcast link window size

      The default fix broadcast window size is currently set to 20 packets.
      This is a very low value, set at a time when we were still testing on
      10 Mb/s hubs, and a change to it is long overdue.

      Commit 7845989cb4b3da1db ("net: tipc: fix stall during bclink wakeup 
procedure")
      revealed a problem with this low value. For messages of importance LOW,
      the backlog queue limit will be  calculated to 30 packets, while a
      single, maximum sized message of 66000 bytes, carried across a 1500 MTU
      network consists of 46 packets.

      This leads to the following scenario (among others leading to the same
      situation):

      1: Msg 1 of 46 packets is sent. 20 packets go to the transmit queue, 26
         packets to the backlog queue.
      2: Msg 2 of 46 packets is attempted sent, but rejected because there is
         no more space in the backlog queue at this level. The sender is added
         to the wakeup queue with a "pending packets chain size" number of 46.
      3: Some packets in the transmit queue are acked and released. We try to
         wake up the sender, but the pending size of 46 is bigger than the LOW
         wakeup limit of 30, so this doesn't happen.
      5: Subsequent acks releases all the remaining buffers. Each time we test
         for the wakeup criteria and find that 46 still is larger than 30,
         even after both the transmit and the backlog queues are empty.
      6: The sender is never woken up and given a chance to send its message.
         He is stuck.

      We could now loosen the wakeup criteria (used by link_prepare_wakeup())
      to become equal to the send criteria (used by tipc_link_xmit()), i.e.,
      by ignoring the "pending packets chain size" value altogether, or we can
      just increase the queue limits so that the criteria can be satisfied
      anyway. There are good reasons (potentially multiple waiting senders) to
      not opt for the former solution, so we choose the latter one.

      This commit fixes the problem by giving the broadcast link window a
      default value of 50 packets. We also introduce a new minimum link
      window size BCLINK_MIN_WIN of 32, which is enough to always avoid the
      described situation. Finally, in order to not break any existing users
      which may set the window explicitly, we enforce that the window is set
      to the new minimum value in case the user is trying to set it to
      anything lower.

      memory for struct btrfs_balance_control has already been allocated.
      Ownership of bctl is passed to btrfs_balance() in the good case,

      drm/nouveau/gem: return only valid domain when there's only one

      On nv50+, we restrict the valid domains to just the one where the buffer
      was originally created. However after the buffer is evicted to system
      memory, we might move it back to a different domain that was not
      originally valid. When sharing the buffer and retrieving its GEM_INFO
      data, we still want the domain that will be valid for this buffer in a
      pushbuf, not the one where it currently happens to be.

      This resolves fdo#92504 and several others. These are due to suspend
      evicting all buffers, making it more likely that they temporarily end up
      in the wrong place.

       "This contains a single fix, for when the IOMMU API is used to overlay
        an existing mapping comprised of 4KiB pages, with a mapping that can
        use superpages.

        For the *first* superpage in the new mapping, we were correctly¹
        freeing the old bottom-level page table page and clearing the link to
        it, before installing the superpage.  For subsequent superpages,
        however, we weren't.  This causes a memory leak, and a warning about
        setting a PTE which is already set.

        ¹ Well, not *entirely* correctly.  We just free the page table pages
          right there and then, which is wrong.  In fact they should only be
          freed *after* the IOTLB is flushed so we know the hardware will no
          longer be looking at them....  and in fact I note that the IOTLB
          flush is completely missing from the intel_iommu_map() code path,
          although it needs to be there if it's permitted to overwrite
          existing mappings.

          Fixing those is somewhat more intrusive though, and will probably

      drm/vmwgfx: Stabilize the command buffer submission code

      This commit addresses some stability problems with the command buffer
      submission code recently introduced:

      1) Make the vmw_cmdbuf_man_process() function handle reruns internally to
      avoid losing interrupts if the caller forgets to rerun on -EAGAIN.
      2) Handle default command buffer allocations using inline command buffers.
      This avoids rare allocation deadlocks.
      3) In case of command buffer errors we might lose fence submissions.
      Therefore send a new fence after each command buffer error. This will help
      avoid lengthy fence waits.

      net: mv643xx_eth: TSO TX data corruption fixes

      as previously discussed [1] the mv643xx_eth driver has some
      issues with data corruption when using TCP segmentation offload (TSO).

      The following patch set improves this situation by fixing two data
      corruption bugs in the TSO TX path.

      Before applying the patches repeatedly accessing large files located on
      a SMB share on my NSA325 NAS with TSO enabled resulted in different
      hash sums, which confirmed that data corruption is happening during
      file transfer. After applying the patches the hash sums were the same.

      As this is my first patch submission please feel free to point out any
      issues with the patch set.

      To prevent a race between the TX DMA engine and the CPU the writing of the
      first transmit descriptor must be deferred until all following descriptors
      have been updated. The network card may otherwise start transmitting 
before
      all packet descriptors are set up correctly, which leads to data 
corruption
      or an aborted transmit operation.

      This deferral is already done in the non-TSO TX path, implement it also in
      the TSO TX path.

      net: mv643xx_eth: Ensure proper data alignment in TSO TX path

      The TX DMA engine requires that buffers with a size of 8 bytes or smaller
      must be 64 bit aligned. This requirement may be violated when doing TSO,
      as in this case larger skb frags can be broken up and transmitted in small
      parts with then inappropriate alignment.

      Fix this by checking for proper alignment before handing a buffer to the
      DMA engine. If the data is misaligned realign it by copying it into the
      TSO header data area.

      arm64: Delay cpu feature capability checks

      At the moment we run through the arm64_features capability list for
      each CPU and set the capability if one of the CPU supports it. This
      could be problematic in a heterogeneous system with differing 
capabilities.
      Delay the CPU feature checks until all the enabled CPUs are up(i.e,
      smp_cpus_done(), so that we can make better decisions based on the
      overall system capability. Once we decide and advertise the capabilities
      the alternatives can be applied. From this state, we cannot roll back
      a feature to disabled based on the values from a new hotplugged CPU,
      due to the runtime patching and other reasons. So, for all new CPUs,
      we need to make sure that they have the established system capabilities.
      Failing which, we bring the CPU down, preventing it from turning online.
      Once the capabilities are decided, any new CPU booting up goes through
      verification to ensure that it has all the enabled capabilities and also
      invokes the respective enable() method on the CPU.

      The CPU errata checks are not delayed and is still executed per-CPU
      to detect the respective capabilities. If we ever come across a non-errata
      capability that needs to be checked on each-CPU, we could introduce them 
via
      a new capability table(or introduce a flag), which can be processed per 
CPU.

      The next patch will make the feature checks use the system wide
      safe value of a feature register.

      NOTE: The enable() methods associated with the capability is scheduled
      on all the CPUs (which is the only use case at the moment). If we need
      a different type of 'enable()' which only needs to be run once on any CPU,
      we should be able to handle that when needed.

      arm64: Keep track of CPU feature registers

      This patch adds an infrastructure to keep track of the CPU feature
      registers on the system. For each register, the infrastructure keeps
      track of the system wide safe value of the feature bits. Also, tracks
      the which fields of a register should be matched strictly across all
      the CPUs on the system for the SANITY check infrastructure.

      The feature bits are classified into following 3 types depending on
      the implication of the possible values. This information is used to
      decide the safe value for a feature.

      LOWER_SAFE  - The smaller value is safer
      HIGHER_SAFE - The bigger value is safer
      EXACT       - We can't decide between the two, so a predefined safe_value 
is used.

      This infrastructure will be later used to make better decisions for:

       - Kernel features (e.g, KVM, Debug)
       - SANITY Check
       - CPU capability
       - ELF HWCAP
       - Exposing CPU Feature register to userspace.

      ====================
      RACK loss detection

      RACK (Recent ACK) loss recovery uses the notion of time instead of
      packet sequence (FACK) or counts (dupthresh).

      It's inspired by the FACK heuristic in tcp_mark_lost_retrans(): when a
      limited transmit (new data packet) is sacked in recovery, then any
      retransmission sent before that newly sacked packet was sent must have
      been lost, since at least one round trip time has elapsed.

      But that existing heuristic from tcp_mark_lost_retrans()
      has several limitations:
        1) it can't detect tail drops since it depends on limited transmit
        2) it's disabled upon reordering (assumes no reordering)
        3) it's only enabled in fast recovery but not timeout recovery

      RACK addresses these limitations with a core idea: an unacknowledged
      packet P1 is deemed lost if a packet P2 that was sent later is is
      s/acked, since at least one round trip has passed.

      Since RACK cares about the time sequence instead of the data sequence
      of packets, it can detect tail drops when a later retransmission is
      s/acked, while FACK or dupthresh can't. For reordering RACK uses a
      dynamically adjusted reordering window ("reo_wnd") to reduce false
      positives on ever (small) degree of reordering, similar to the delayed
      Early Retransmit.

      In the current patch set RACK is only a supplemental loss detection
      and does not trigger fast recovery. However we are developing RACK
      to replace or consolidate FACK/dupthresh, early retransmit, and
      thin-dupack. These heuristics all implicitly bear the time notion.
      For example, the delayed Early Retransmit is simply applying RACK
      to trigger the fast recovery with small inflight.

      RACK requires measuring the minimum RTT. Tracking a global min is less
      robust due to traffic engineering pathing changes. Therefore it uses a
      windowed filter by Kathleen Nichols. The min RTT can also be useful
      for various other purposes like congestion control or stat monitoring.

      This patch has been used on Google servers for well over 1 year. RACK
      has also been implemented in the QUIC protocol. We are submitting an
      IETF draft as well.

      tcp: use RACK to detect losses

      This patch implements the second half of RACK that uses the the most
      recent transmit time among all delivered packets to detect losses.

      tcp_rack_mark_lost() is called upon receiving a dubious ACK.
      It then checks if an not-yet-sacked packet was sent at least
      "reo_wnd" prior to the sent time of the most recently delivered.
      If so the packet is deemed lost.

      The "reo_wnd" reordering window starts with 1msec for fast loss
      detection and changes to min-RTT/4 when reordering is observed.
      We found 1msec accommodates well on tiny degree of reordering
      (<3 pkts) on faster links. We use min-RTT instead of SRTT because
      reordering is more of a path property but SRTT can be inflated by
      self-inflicated congestion. The factor of 4 is borrowed from the
      delayed early retransmit and seems to work reasonably well.

      Since RACK is still experimental, it is now used as a supplemental
      loss detection on top of existing algorithms. It is only effective
      after the fast recovery starts or after the timeout occurs. The
      fast recovery is still triggered by FACK and/or dupack threshold
      instead of RACK.

      We introduce a new sysctl net.ipv4.tcp_recovery for future
      experiments of loss recoveries. For now RACK can be disabled by
      setting it to 0.

      tcp: track the packet timings in RACK

      This patch is the first half of the RACK loss recovery.

      RACK loss recovery uses the notion of time instead
      of packet sequence (FACK) or counts (dupthresh). It's inspired by the
      previous FACK heuristic in tcp_mark_lost_retrans(): when a limited
      transmit (new data packet) is sacked, then current retransmitted
      sequence below the newly sacked sequence must been lost,
      since at least one round trip time has elapsed.

      But it has several limitations:
      1) can't detect tail drops since it depends on limited transmit
      2) is disabled upon reordering (assumes no reordering)
      3) only enabled in fast recovery ut not timeout recovery

      RACK (Recently ACK) addresses these limitations with the notion
      of time instead: a packet P1 is lost if a later packet P2 is s/acked,
      as at least one round trip has passed.

      Since RACK cares about the time sequence instead of the data sequence
      of packets, it can detect tail drops when later retransmission is
      s/acked while FACK or dupthresh can't. For reordering RACK uses a
      dynamically adjusted reordering window ("reo_wnd") to reduce false
      positives on ever (small) degree of reordering.

      This patch implements tcp_advanced_rack() which tracks the
      most recent transmission time among the packets that have been
      delivered (ACKed or SACKed) in tp->rack.mstamp. This timestamp
      is the key to determine which packet has been lost.

      Consider an example that the sender sends six packets:
      T1: P1 (lost)
      T2: P2
      T3: P3
      T4: P4
      T100: sack of P2. rack.mstamp = T2
      T101: retransmit P1
      T102: sack of P2,P3,P4. rack.mstamp = T4
      T205: ACK of P4 since the hole is repaired. rack.mstamp = T101

      We need to be careful about spurious retransmission because it may
      falsely advance tp->rack.mstamp by an RTT or an RTO, causing RACK
      to falsely mark all packets lost, just like a spurious timeout.

      We identify spurious retransmission by the ACK's TS echo value.
      If TS option is not applicable but the retransmission is acknowledged
      less than min-RTT ago, it is likely to be spurious. We refrain from
      using the transmission time of these spurious retransmissions.

      The second half is implemented in the next patch that marks packet
      lost using RACK timestamp.

      tcp: track min RTT using windowed min-filter

      Kathleen Nichols' algorithm for tracking the minimum RTT of a
      data stream over some measurement window. It uses constant space
      and constant time per update. Yet it almost always delivers
      the same minimum as an implementation that has to keep all
      the data in the window. The measurement window is tunable via
      sysctl.net.ipv4.tcp_min_rtt_wlen with a default value of 5 minutes.

      The algorithm keeps track of the best, 2nd best & 3rd best min
      values, maintaining an invariant that the measurement time of
      the n'th best >= n-1'th best. It also makes sure that the three
      values are widely separated in the time window since that bounds
      the worse case error when that data is monotonically increasing
      over the window.

      Upon getting a new min, we can forget everything earlier because
      it has no value - the new min is less than everything else in the
      window by definition and it's the most recent. So we restart fresh
      on every new min and overwrites the 2nd & 3rd choices. The same
      property holds for the 2nd & 3rd best.

      Therefore we have to maintain two invariants to maximize the
      information in the samples, one on values (1st.v <= 2nd.v <=
      3rd.v) and the other on times (now-win <=1st.t <= 2nd.t <= 3rd.t <=
      now). These invariants determine the structure of the code

      The RTT input to the windowed filter is the minimum RTT measured
      from ACK or SACK, or as the last resort from TCP timestamps.

      The accessor tcp_min_rtt() returns the minimum RTT seen in the
      window. ~0U indicates it is not available. The minimum is 1usec
      even if the true RTT is below that.

        - I did not change disable property name into enable
          because I fear to break existing behaviour

      net: phy: smsc: disable energy detect mode

      On some boards the energy enable detect mode leads in
      trouble with some switches, so make the enabling of
      this mode configurable through DT.

      bcm63xx_enet: check 1000BASE-T advertisement configuration

      If a gigabit ethernet PHY is connected to a fast ethernet MAC,
      then it can detect 1000 support from the partner but not use it.

      This results in a forced speed of 1000 and RX/TX failure.

      Check for 1000BASE-T support and then check the advertisement
      configuration before setting the MAC speed to 1000mbit.

      Intel Wired LAN Driver Updates 2015-10-19

      This series contains updates to i40e and i40evf only.

      Kiran adds a spinlock around code accessing VSI MAC filter list to
      ensure that we are synchronizing access to the filter list, otherwise
      we can end up with multiple accesses at the same time which can cause
      the VSI MAC filter list to get in an unstable or corrupted state.

      Jesse fixes overlong BIT defines, where the RSS enabling call were
      mistakenly missed.  Also fixes a bug where the enable function was
      enabling the interrupt twice while trying to update the two interrupt
      throttle rate thresholds for Rx and Tx, while refactoring the IRQ
      enable function to simplify reading the flow.  Addressed the high
      CPU utilization of some small streaming workloads that the driver should
      reduce CPU in.

      Anjali fixes two X722 issues with respect to EEPROM checksum verify and
      reading NVM version info.  Fixed where a mask value was accidentally
      replaced with a bit mask causing Flow Director sideband to be broken.

      Alex Duyck fixes areas of the drivers which run from hard interrupt
      context or with interrupts already disabled in netpoll, so use
      napi_schedule_irqoff() instead of napi_schedule().

      Mitch fixes the VF drivers to not easily give up when it is not able
      to communicate with the PF driver.

      Carolyn fixes a problem where our tools MAC loopback test, after driver
      unbind would fail because the hardware was configured for multiqueue and
      unbind operation did not clear this configuration.  Also fixed a issue
      where the NVMUpdate tool gets bad data from the PHY when using the PHY
      NVM feature because of contention on the MDIO interface from getting
      PHY capability calls from the driver during regular operations.

      Catherine fixed an issue where we were checking if autoneg was allowed
      to change before checking if autoneg was changing, these checks need to
      be in the reverse order.

      Jean Sacren fixes up an function header comment to align the kernel-docs
      with the actual code.

      v2: Cleaned up the use of spin_is_locked() in patch 1 based on feedback
          from David Miller, since it always evaluates to zero on uni-processor
          builds

      Bluetooth: Fix missing hdev locking for LE scan cleanup

      The hci_conn objects don't have a dedicated lock themselves but rely
      on the caller to hold the hci_dev lock for most types of access. The
      hci_conn_timeout() function has so far sent certain HCI commands based
      on the hci_conn state which has been possible without holding the
      hci_dev lock.

      The recent changes to do LE scanning before connect attempts added
      even more operations to hci_conn and hci_dev from hci_conn_timeout,
      thereby exposing potential race conditions with the hci_dev and
      hci_conn states.

      As an example of such a race, here there's a timeout but an
      l2cap_sock_connect() call manages to race with the cleanup routine:

      [Oct21 08:14] l2cap_chan_timeout: chan ee4b12c0 state BT_CONNECT

      [  +0.000003] hci_conn_hold: hcon f53d56e0 orig refcnt 0

      Above the l2cap_chan_connect() shouldn't have been able to reach the
      hci_conn f53d56e0 anymore but since hci_conn_timeout didn't do proper
      locking that's not the case. The end result is a reference to hci_conn
      that's not in the conn_hash list, resulting in list corruption when
      trying to remove it later:

      [Oct21 08:15] l2cap_chan_timeout: chan ee4b1770 state BT_CONNECT

(00000200)

      The necessary fix is unfortunately more complicated than just adding
      hci_dev_lock/unlock calls to the hci_conn_timeout() call path.
      Particularly, the hci_conn_del() API, which expects the hci_dev lock to
      be held, performs a cancel_delayed_work_sync(&hcon->disc_work) which
      would lead to a deadlock if the hci_conn_timeout() call path tries to
      acquire the same lock.

      This patch solves the problem by deferring the cleanup work to a
      separate work callback. To protect against the hci_dev or hci_conn
      going away meanwhile temporary references are taken with the help of
      hci_dev_hold() and hci_conn_get().

      powerpc/powernv: Handle irq_happened flag correctly in off-line loop

      This fixes a bug where it is possible for an off-line CPU to fail to go
      into a low-power state (nap/sleep/winkle), and to become unresponsive to
      requests from the KVM subsystem to wake up and run a VCPU. What can
      happen is that a maskable interrupt of some kind (external, decrementer,
      hypervisor doorbell, or HMI) after we have called local_irq_disable() at
      the beginning of pnv_smp_cpu_kill_self() and before interrupts are
      hard-disabled inside power7_nap/sleep/winkle(). In this situation, the
      pending event is marked in the irq_happened flag in the PACA. This
      pending event prevents power7_nap/sleep/winkle from going to the
      requested low-power state; instead they return immediately. We don't
      deal with any of these pending event flags in the off-line loop in
      pnv_smp_cpu_kill_self() because power7_nap et al. return 0 in this case,
      so we will have srr1 == 0, and none of the processing to clear
      interrupts or doorbells will be done.

      Usually, the most obvious symptom of this is that a KVM guest will fail
      with a console message saying "KVM: couldn't grab cpu N".

      This fixes the problem by making sure we handle the irq_happened flags
      properly. First, we hard-disable before the off-line loop. Once we have
      hard-disabled, the irq_happened flags can't change underneath us. We
      unconditionally clear the DEC and HMI flags: there is no processing of
      timer interrupts while off-line, and the necessary HMI processing is all
      done in lower-level code. We leave the EE and DBELL flags alone for the
      first iteration of the loop, so that we won't fail to respond to a
      split-core request that came in just before hard-disabling. Within the
      loop, we handle external interrupts if the EE bit is set in irq_happened
      as well as if the low-power state was interrupted by an external
      interrupt. (We don't need to do the msgclr for a pending doorbell in
      irq_happened, because doorbells are edge-triggered and don't remain
      pending in hardware.) Then we clear both the EE and DBELL flags, and
      once clear, they cannot be set again (until this CPU comes online again,
      that is).

      This also fixes the debug check to not be done when we just ran a KVM
      guest or when the sleep didn't happen because of a pending event in
      irq_happened.

      powerpc: Revert "Use the POWER8 Micro Partition Prefetch Engine in KVM HV 
on POWER8"

      This reverts commit 9678cdaae939 ("Use the POWER8 Micro Partition
      Prefetch Engine in KVM HV on POWER8") because the original commit had
      multiple, partly self-cancelling bugs, that could cause occasional
      memory corruption.

      In fact the logmpp instruction was incorrectly using register r0 as the
      source of the buffer address and operation code, and depending on what
      was in r0, it would either do nothing or corrupt the 64k page pointed to
      by r0.

      The logmpp instruction encoding and the operation code definitions could
      be corrected, but then there is the problem that there is no clearly
      defined way to know when the hardware has finished writing to the
      buffer.

      The original commit attempted to work around this by aborting the
      write-out before starting the prefetch, but this is ineffective in the
      case where the virtual core is now executing on a different physical
      core from the one where the write-out was initiated.

      These problems plus advice from the hardware designers not to use the
      function (since the measured performance improvement from using the
      feature was actually mostly negative), mean that reverting the code is
      the best option.

      x86/microcode: Unmodularize the microcode driver

      Make CONFIG_MICROCODE a bool. It was practically a bool already anyway,
      since early loader was forcing it to =y.

      Regardless, there's no real reason to have something be a module which
      gets built-in on the majority of installations out there. And its not
      like there's noticeable change in functionality - we still can load late
      microcode - just the module glue disappears.

      x86/mce: Fix thermal throttling reporting after kexec

      The per CPU thermal vector init code checks if the thermal
      vector is already installed and complains and bails out if it
      is.

      This happens after kexec, as kernel shut down does not clear the
      thermal vector APIC register.

      This causes two problems:

      1. So we always do not fully initialize thermal reports after
         kexec. The CPU is still likely initialized, as the previous
         kernel should have done it. But we don't set up the software
         pointer to the thermal vector, so reporting may end up with a
         unknown thermal interrupt message.

      2. Also it complains for every logical CPU, even though the
         value is actually derived from BP only.

      The problem is that we end up with one message per CPU, so on
      larger systems it becomes very noisy and messes up the otherwise
      nicely formatted CPU bootup numbers in the kernel log.

      Just remove the check. I checked the code and there's no valid
      code paths where the thermal init code for a CPU could be called
      multiple times.

      Why the kernel does not clean up this value on shutdown:

      The thermal monitoring is controlled per logical CPU thread.
      Normal shutdown code is just running on one CPU. To disable it
      we would need a broadcast NMI to all CPUs on shut down. That's
      overkill for this. So we just ignore it after kexec.

      x86/setup: Do not reserve crashkernel high memory if low reservation 
failed

      People reported that when allocating crashkernel memory using
      the ",high" and ",low" syntax, there were cases where the
      reservation of the high portion succeeds but the reservation of
      the low portion fails.

      Then kexec can load the kdump kernel successfully, but booting
      the kdump kernel fails as there's no low memory.

      The low memory allocation for the kdump kernel can fail on large
      systems for a couple of reasons. For example, the manually
      specified crashkernel low memory can be too large and thus no
      adequate memblock region would be found.

      Therefore, we try to reserve low memory for the crash kernel
      *after* the high memory portion has been allocated. If that
      fails, we free crashkernel high memory too and return. The user
      can then take measures accordingly.

      mmc: core: Fix init_card in 52Mhz

      Suppose that we got a data crc error, and it triggers the mmc_reset.
      mmc_reset will call mmc_send_status to see if HW reset was supported.
      before issue CMD13, it will do retune, and if EMMC was in HS400 mode,
      it will reduce frequency to 52Mhz firstly, then results in card init
      was doing at 52Mhz.
      The mmc_send_status was originally only done for mmc_test, should drop
      it. And, rename the "eMMC hardware reset" to "Reset test", as we would
      also be able to use the test for SD-cards.

      Group station statistics by where they're (mostly) updated

      Also rename the variables since the grouping now makes it

      New driver: rtl8xxxu (mac80211)

      This is an alternate driver for a number of Realtek WiFi USB devices,
      including RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU.
      It was written from scratch utilizing the Linux mac80211 stack.

      After spending months cleaning up the vendor provided rtl8723au
      driver, which comes with it's own 802.11 stack included, I decided to
      rewrite this driver from the bottom up.

      Many thanks to Johannes Berg for 802.11 insights and help and Larry
      Finger for help with the vendor driver.

      The full git log for the development of this driver can be found here:
      git git://git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git
          branch rtl8723au-mac80211

      This driver is still under development, but has proven to be very
      stable for me. It currently supports station mode only. It has support
      for OFDM and CCK rates. It does lack certain features found in the
      staging driver, such as power management, AMPDU, and 40MHz channel
      support. In addition it does not support AD-HOC, AP, and monitor mode
      support at this point.

      The driver is known to work with the following devices:
      Lenovo Yoga (rtl8723au)
      TP-Link TL-WN823N (rtl8192cu)
      Etekcity 6R (rtl8188cu)
      Daffodil LAN03 (rtl8188cu)

      btrfs: Avoid truncate tailing page if fallocate range doesn't exceed 
inode size

      Current code will always truncate tailing page if its alloc_start is
      smaller than inode size.

      For example, the file extent layout is like:
      0 4K      8K      16K     32K
      |<-----Extent A---------------->|
      |<--Inode size: 18K---------->|

      But if calling fallocate even for range [0,4K), it will cause btrfs to
      re-truncate the range [16,32K), causing COW and a new extent.

      0 4K      8K      16K     32K
      |///////| <- Fallocate call range
      |<-----Extent A-------->|<--B-->|

      The cause is quite easy, just a careless btrfs_truncate_inode() in a
      else branch without extra judgment.
      Fix it by add judgment on whether the fallocate range is beyond isize.

      spinlocks and stack tracing an NMI gives the possibility of causing a

stack
      traces when the task struct stack is not in use (interrupts and NMIs), it
      may be an issue for NMIs on i386 and other archs that use the same stack 
as

      Bluetooth: l2cap_disconnection_req priority over shutdown

      There is a L2CAP protocol race between the local peer and
      the remote peer demanding disconnection of the L2CAP link.

      When L2CAP ERTM is used, l2cap_sock_shutdown() can be called
      from userland to disconnect L2CAP. However, there can be a
      delay introduced by waiting for ACKs. During this waiting
      period, the remote peer may have sent a Disconnection Request.
      Therefore, recheck the shutdown status of the socket
      after waiting for ACKs because there is no need to do
      further processing if the connection has gone.

      Bluetooth: Reorganize mutex lock in l2cap_sock_shutdown()

      This commit reorganizes the mutex lock and is now
      only protecting l2cap_chan_close(). This is now consistent
      with other places where l2cap_chan_close() is called.

      If a conn connection exists, call
      mutex_lock(&conn->chan_lock) before calling l2cap_chan_close()
      to ensure other L2CAP protocol operations do not interfere.

      Note that the conn structure has to be protected from being
      freed as it is possible for the connection to be disconnected
      whilst the locks are not held. This solution allows the mutex
      lock to be used even when the connection has just been
      disconnected.

      This commit also reduces the scope of chan locking.

      The only place where chan locking is needed is the call to
      l2cap_chan_close(chan, 0) which if necessary closes the channel.
      Therefore, move the l2cap_chan_lock(chan) and
      l2cap_chan_lock(chan) locking calls to around
      l2cap_chan_close(chan, 0).

      This allows __l2cap_wait_ack(sk, chan) to be called with no
      chan locks being held so L2CAP messaging over the ACL link
      can be done unimpaired.

      Bluetooth: Unwind l2cap_sock_shutdown()

      l2cap_sock_shutdown() is designed to only action shutdown

      6lowpan: rework tc and flow label handling

      This patch reworks the handling of compression/decompression of traffic
      class and flow label handling. The current method is hard to understand,
      also doesn't checks if we can read the buffer from skb length.

      I tried to put the shifting operations into static inline functions and
      comment each steps which I did there to make it hopefully somewhat more
      readable. The big mess to deal with that is the that the ipv6 header
      bring the order "DSCP + ECN" but iphc uses "ECN + DSCP". Additional the
      DCSP + ECN bits are splitted in ipv6_hdr inside the priority and
      flow_lbl[0] fields.

      I tested these compressions by using fakelb 802.15.4 driver and
      manipulate the tc and flow label fields manually in function
      "__ip6_local_out" before the skb will be send to lower layers. Then I
      looked up the tc and flow label fields in wireshark on a wpan and lowpan
      interface.

      all possible SAM values over a switch case statement. We will not

      Additional this patch slighty change the naming style like RFC 6282,

      6lowpan: remove lowpan_fetch_skb_u8

      This patch removes the lowpan_fetch_skb_u8 function for getting the iphc
      bytes. Instead we using the generic which has a len parameter to tell
      the amount of bytes to fetch.

      6lowpan: cleanup lowpan_header_decompress

      This patch changes the lowpan_header_decompress function by removing
      inklayer related information from parameters. This is currently for
      supporting short and extended address for iphc handling in 802154.
      We don't support short address handling anyway right now, but there
      exists already code for handling short addresses in
      lowpan_header_decompress.

      The address parameters are also changed to a void pointer, so 6LoWPAN
      linklayer specific code can put complex structures as these parameters
      and cast it again inside the generic code by evaluating linklayer type
      before. The order is also changed by destination address at first and
      then source address, which is the same like all others functions where
      destination is always the first, memcpy, dev_hard_header,
      lowpan_header_compress, etc.

      This patch also moves the fetching of iphc values from 6LoWPAN linklayer
      specific code into the generic branch.

      6lowpan: cleanup lowpan_header_compress

      This patch changes the lowpan_header_compress function by removing
      unused parameters like "len" and drop static value parameters of
      protocol type. Instead we really check the protocol type inside inside
      the skb structure. Also we drop the use of IEEE802154_ADDR_LEN which is
      link-layer specific. Instead we using EUI64_ADDR_LEN which should always
      the default case for now.

      Bluetooth: Fix removing connection parameters when unpairing

      The commit 89cbb0638e9b7 introduced support for deferred connection
      parameter removal when unpairing by removing them only once an
      existing connection gets disconnected. However, it failed to address
      the scenario when we're *not* connected and do an unpair operation.

      What makes things worse is that most user space BlueZ versions will
      first issue a disconnect request and only then unpair, meaning the
      buggy code will be triggered every time. This effectively causes the
      kernel to resume scanning and reconnect to a device for which we've
      removed all keys and GATT database information.

      This patch fixes the issue by adding the missing call to the
      hci_conn_params_del() function to a branch which handles the case of
      no existing connection.

      The general layout of Bluetooth devices is that interface 0 is the main
      interface and interface 1 is for audio data. This design obviously moves
      it to main interface 2 and audio data on interface 3.

      Starting with the MacBookPro12,1 (early 2015 models) the new Broadcom
      BCM943602CS cards are used which show this interface layout.

      Bluetooth: Add support setup stage internal notification event

      Before the vendor specific setup stage is triggered call back into the
      core to trigger an internal notification event. That event is used to
      send an index update to the monitor interface. With that specific event
      it is possible to update userspace with manufacturer information before
      any HCI command has been executed. This is useful for early stage
      debugging of vendor specific initialization sequences.

      Support for the chipset was added in commit 88f9b65 and a similar BCM43142

      Bluetooth: hidp: fix device disconnect on idle timeout

      The HIDP specs define an idle-timeout which automatically disconnects a
      device. This has always been implemented in the HIDP layer and forced a
      synchronous shutdown of the hidp-scheduler. This works just fine, but
      lacks a forced disconnect on the underlying l2cap channels. This has been
      broken since:

          commit 5205185d461d5902325e457ca80bd421127b7308

              Bluetooth: hidp: remove old session-management

      The old session-management always forced an l2cap error on the ctrl/intr
      channels when shutting down. The new session-management skips this, as we
      don't want to enforce channel policy on the caller. In other words, if
      user-space removes an HIDP device, the underlying channels (which are
      *owned* and *referenced* by user-space) are still left active. User-space
      needs to call shutdown(2) or close(2) to release them.

      Unfortunately, this does not work with idle-timeouts. There is no way to
      signal user-space that the HIDP layer has been stopped. The API simply
      does not support any event-passing except for poll(2). Hence, we restore
      old behavior and force EUNATCH on the sockets if the HIDP layer is
      disconnected due to idle-timeouts (behavior of explicit disconnects
      remains unmodified). User-space can still call

          getsockopt(..., SO_ERROR, ...)

      ..to retrieve the EUNATCH error and clear sk_err. Hence, the channels can
      still be re-used (which nobody does so far, though). Therefore, the API
      still supports the new behavior, but with this patch it's also compatible
      to the old implicit channel shutdown.

      Bluetooth: bpa10x: fix BT_HCIUART dependency

      The change to bpa10x to use the h4_recv_buf helper added a dependency
      on BT_HCIUART. This was incorrectly added to Kconfig by adding a
      'select' statement, which now in turn causes build failures
      when CONFIG_TTY is not set:

      warning: (BT_HCIBPA10X) selects BT_HCIUART which has unmet direct 
dependencies (NET && BT && TTY)
      vers/built-in.o: In function `hci_uart_tty_receive':
      fpga-mgr.c:(.text+0x282824): undefined reference to `tty_unthrottle'
      drivers/built-in.o: In function `hci_uart_tty_ioctl':
      fpga-mgr.c:(.text+0x282aa0): undefined reference to `n_tty_ioctl_helper'
      drivers/built-in.o: In function `hci_uart_flush':

      This replaces the 'select BT_HCIUART' dependency with 'depends on', which
      does not have this kind of problem. Alternatively, one could add 'depends
      on TTY', but avoiding 'select' on user-visible options is generally the
      preferred choice as that does not introduce the potential for dependency
      loops or incomplete dependency chains.

      There are LE devices on the market that start off by announcing their
      public address and then once paired switch to using private address.
      To be interoperable with such devices we should simply trust the fact
      that we're receiving an IRK from them to indicate that they may use
      private addresses in the future. Instead, simply tie the persistency
      to the bonding/no-bonding information the same way as for LTKs and
      CSRKs.

      perf cpu_map: Fix core dump caused by per-socket/core system-wide stat

      Perf will core dump if --per-socket/core -a are applied for perf stat.

      The root cause is that cpu_map__build_map set refcnt of evlist's cpu_map
      to 1.  It should set refcnt for the newly created cpu_map, not evlist's
      cpu_map.

      Here is the example:

        # perf stat -e cycles --per-socket -a sleep 1

         Performance counter stats for 'system wide':

        S0       36         30,196,257      cycles

      IB/cma: Use inner P_Key to determine netdev

      When discussing the patches to demux ids in rdma_cm instead of ib_cm, it
      was decided that it is best to use the P_Key value in the packet headers.
      However, the mlx5 and ipath drivers are currently unable to send correct
      P_Key values in GMP headers. They always send using a single P_Key that is
      set during the GSI QP initialization.

      Change the rdma_cm code to look at the P_Key value that is part of the
      packet payload as a workaround. Once the drivers are fixed this patch can
      be reverted.

      arm/arm64: KVM: Fix disabled distributor operation

      We currently do a single update of the vgic state when the distributor
      enable/disable control register is accessed and then bypass updating the
      state for as long as the distributor remains disabled.

      This is incorrect, because updating the state does not consider the
      distributor enable bit, and this you can end up in a situation where an
      interrupt is marked as pending on the CPU interface, but not pending on
      the distributor, which is an impossible state to be in, and triggers a
      warning.  Consider for example the following sequence of events:

      1. An interrupt is marked as pending on the distributor
         - the interrupt is also forwarded to the CPU interface
      2. The guest turns off the distributor (it's about to do a reboot)
         - we stop updating the CPU interface state from now on
      3. The guest disables the pending interrupt
         - we remove the pending state from the distributor, but don't touch
           the CPU interface, see point 2.

      Since the distributor disable bit really means that no interrupts should
      be forwarded to the CPU interface, we modify the code to keep updating
      the internal VGIC state, but always set the CPU interface pending bits
      to zero when the distributor is disabled.

      arm/arm64: KVM: Clear map->active on pend/active clear

      When a guest reboots or offlines/onlines CPUs, it is not uncommon for it
      to clear the pending and active states of an interrupt through the
      emulated VGIC distributor.  However, since the architected timers are
      defined by the architecture to be level triggered and the guest
      rightfully expects them to be that, but we emulate them as
      edge-triggered, we have to mimic level-triggered behavior for an
      edge-triggered virtual implementation.

      We currently do not signal the VGIC when the map->active field is true,
      because it indicates that the guest has already been signalled of the
      interrupt as required.  Normally this field is set to false when the
      guest deactivates the virtual interrupt through the sync path.

      We also need to catch the case where the guest deactivates the interrupt
      through the emulated distributor, again allowing guests to boot even if
      the original virtual timer signal hit before the guest's GIC
      initialization sequence is run.

      arm/arm64: KVM: Fix arch timer behavior for disabled interrupts

      We have an interesting issue when the guest disables the timer interrupt
      on the VGIC, which happens when turning VCPUs off using PSCI, for
      example.

      The problem is that because the guest disables the virtual interrupt at
      the VGIC level, we never inject interrupts to the guest and therefore
      never mark the interrupt as active on the physical distributor.  The
      host also never takes the timer interrupt (we only use the timer device
      to trigger a guest exit and everything else is done in software), so the
      interrupt does not become active through normal means.

      The result is that we keep entering the guest with a programmed timer
      that will always fire as soon as we context switch the hardware timer
      state and run the guest, preventing forward progress for the VCPU.

      Since the active state on the physical distributor is really part of the
      timer logic, it is the job of our virtual arch timer driver to manage
      this state.

      The timer->map->active boolean field indicates whether we have signalled
      this interrupt to the vgic and if that interrupt is still pending or
      active.  As long as that is the case, the hardware doesn't have to
      generate physical interrupts and therefore we mark the interrupt as
      active on the physical distributor.

      We also have to restore the pending state of an interrupt that was
      queued to an LR but was retired from the LR for some reason, while
      remaining pending in the LR.

      KVM: arm: use GIC support unconditionally

      The vgic code on ARM is built for all configurations that enable KVM,
      but the parent_data field that it references is only present when
      CONFIG_IRQ_DOMAIN_HIERARCHY is set:

      virt/kvm/arm/vgic.c: In function 'kvm_vgic_map_phys_irq':
      virt/kvm/arm/vgic.c:1781:13: error: 'struct irq_data' has no member named 
'parent_data'

      This flag is implied by the GIC driver, and indeed the VGIC code only
      makes sense if a GIC is present. This changes the CONFIG_KVM symbol
      to always select GIC, which avoids the issue.

      tracing: Have stack tracer force RCU to be watching

      The stack tracer was triggering the WARN_ON() in module.c:

       static void module_assert_mutex_or_preempt(void)
       {
       #ifdef CONFIG_LOCKDEP
        if (unlikely(!debug_locks))
                return;

        WARN_ON(!rcu_read_lock_sched_held() &&
                !lockdep_is_held(&module_mutex));
       #endif
       }

      The reason is that the stack tracer traces all function calls, and some of
      those calls happen while exiting or entering user space and idle. Some of
      these functions are called after RCU had already stopped watching, as RCU
      does not watch userspace or idle CPUs.

      If a max stack is hit, then the save_stack_trace() is called, which will
      check module addresses and call module_assert_mutex_or_preempt(), and then
      trigger the warning. Sad part is, the warning itself will also do a stack
      trace and tigger the same warning. That probably should be fixed.

      The warning was added by 0be964be0d45 "module: Sanitize RCU usage and
      locking" but this bug has probably been around longer. But it's unlikely 
to
      cause much harm, but the new warning causes the system to lock up.

      crypto: caam - fix non-block aligned hash calculation

      caam does not properly calculate the size of the retained state
      when non-block aligned hashes are requested - it uses the wrong
      buffer sizes, which results in errors such as:

      caam_jr 2102000.jr1: 40000501: DECO: desc idx 5: SGT Length Error. The 
descriptor is trying to read more data than is contained in the SGT table.

      We end up here with:

      in_len 0x46 blocksize 0x40 last_bufsize 0x0 next_bufsize 0x6
      to_hash 0x40 ctx_len 0x28 nbytes 0x20

      which results in a job descriptor of:

      jobdesc@889: ed03d918: b0861c08 3daa0080 f1400000 3d03d938
      jobdesc@889: ed03d928: 00000068 f8400000 3cde2a40 00000028

      where the word at 0xed03d928 is the expected data size (0x68), and a
      scatterlist containing:

      sg@892: ed03d938: 00000000 3cde2a40 00000028 00000000
      sg@892: ed03d948: 00000000 3d03d100 00000006 00000000
      sg@892: ed03d958: 00000000 7e8aa700 40000020 00000000

      0x68 comes from 0x28 (the context size) plus the "in_len" rounded down
      to a block size (0x40).  in_len comes from 0x26 bytes of unhashed data
      from the previous operation, plus the 0x20 bytes from the latest
      operation.

      The fixed version would create:

      sg@892: ed03d938: 00000000 3cde2a40 00000028 00000000
      sg@892: ed03d948: 00000000 3d03d100 00000026 00000000
      sg@892: ed03d958: 00000000 7e8aa700 40000020 00000000

      which replaces the 0x06 length with the correct 0x26 bytes of previously
      unhashed data.

      This fixes a previous commit which erroneously "fixed" this due to a
      DMA-API bug report; that commit indicates that the bug was caused via a
      test_ahash_pnum() function in the tcrypt module.  No such function has
      ever existed in the mainline kernel.  Given that the change in this
      commit has been tested with DMA API debug enabled and shows no issue,
      I can only conclude that test_ahash_pnum() was triggering that bad
      behaviour by CAAM.

      We prepare the padding to be appended, and then append as much of the
      padding to any existing data that's already queued up, adding an
      operation block and launching the operation.

      Any remainder is then appended as a separate operation.

      This ensures that the hardware only ever sees multiples of the hash
      block size to be operated on for software padded hashes, thus ensuring
      that the engine always indicates that it has finished the calculation.

      crypto: marvell/cesa - ensure iter.base.op_len is the full op length

      When we process the last request of data, and the request contains user
      data, the loop in mv_cesa_ahash_dma_req_init() marks the first data size
      as being iter.base.op_len which does not include the size of the cache
      data.  This means we end up hashing an insufficient amount of data.

      Fix this by always including the cache size in the first operation
      length of any request.

      This has the effect that for a request containing no user data,

        iter.base.op_len === iter.src.op_offset === creq->cache_ptr

      As a result, we include one further change to use iter.base.op_len in
      the cache-but-no-user-data case to make the next change clearer.

        iter.base.op_len == 0 === iter.src.sg

      In doing so, we can:

      1. eliminate the test for iter.base.op_len inside the loop, which
         makes the loop operation more obvious and understandable.

      2. move the operation generation for the cache-only case.

      crypto: marvell/cesa - move mv_cesa_dma_add_frag() calls

      Move the calls to mv_cesa_dma_add_frag() into the parent function,
      mv_cesa_ahash_dma_req_init().  This is in preparation to changing
      when we generate the operation blocks, as we need to avoid generating
      a block for a partial hash block at the end of the user data.

      crypto: marvell/cesa - always ensure mid-fragments after first-fragment

      If we add a template first-fragment operation, always update the
      template to be a mid-fragment.  This ensures that mid-fragments
      always follow on from a first fragment in every case.

      This means we can move the first to mid-fragment update code out of
      mv_cesa_ahash_dma_add_data().

      crypto: marvell/cesa - factor out adding an operation and launching it

      Add a helper to add the fragment operation block followed by the DMA
      entry to launch the operation.

      Although at the moment this pattern only strictly appears at one site,
      two other sites can be factored as well by slightly changing the order
      in which the DMA operations are performed.  This should be harmless as
      the only thing which matters is to have all the data loaded into SRAM
      prior to launching the operation.

      crypto: marvell/cesa - factor out first fragment decisions to helper

      Multiple locations in the driver test the operation context fragment
      type, checking whether it is a first fragment or not.  Introduce a
      mv_cesa_mac_op_is_first_frag() helper, which returns true if the
      fragment operation is for a first fragment.

      crypto: marvell/cesa - fix the bit length endianness

      The endianness of the bit length used in the final stage depends on the
      endianness of the algorithm - md5 hashes need it to be in little endian
      format, whereas SHA hashes need it in big endian format.  Use the
      previously added algorithm endianness flag to control this.

      Currently, we read/write the state in CPU endian, but on the final

      crypto: api - Only abort operations on fatal signal

      Currently a number of Crypto API operations may fail when a signal
      occurs.  This causes nasty problems as the caller of those operations
      are often not in a good position to restart the operation.

      In fact there is currently no need for those operations to be
      interrupted by user signals at all.  All we need is for them to
      be killable.

      This patch replaces the relevant calls of signal_pending with
      fatal_signal_pending, and wait_for_completion_interruptible with
      wait_for_completion_killable, respectively.

      compiler, atomics, kasan: Provide READ_ONCE_NOCHECK()

      Some code may perform racy by design memory reads. This could be
      harmless, yet such code may produce KASAN warnings.

      To hide such accesses from KASAN this patch introduces
      READ_ONCE_NOCHECK() macro. KASAN will not check the memory
      accessed by READ_ONCE_NOCHECK(). The KernelThreadSanitizer
      (KTSAN) is going to ignore it as well.

      This patch creates __read_once_size_nocheck() a clone of
      __read_once_size(). The only difference between them is
      'no_sanitized_address' attribute appended to '*_nocheck'
      function. This attribute tells the compiler that instrumentation
      of memory accesses should not be applied to that function. We
      declare it as static '__maybe_unsed' because GCC is not capable
      to inline such function:
      https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67368

      With KASAN=n READ_ONCE_NOCHECK() is just a clone of READ_ONCE().

      perf record: Add ability to sample call branches

      This patch add a new branch type sampling filter to perf record.
      It is named 'call' and maps to PERF_SAMPLE_BRANCH_CALL. It samples
      direct call branches only, unlike 'any_call' which includes indirect
      calls as well.

       $ perf record -j call -e cycles .....

      The man page is updated accordingly.

      perf: Add PERF_SAMPLE_BRANCH_CALL

      Add a new branch sample type to cover only call branches (function calls).
      The current ANY_CALL included direct, indirect calls and far jumps.

      We want to be able to differentiate indirect from direct calls. Therefore
      we introduce PERF_SAMPLE_BRANCH_CALL. The implementation is up to each
      architecture.

      perf/x86: Fix time_shift in perf_event_mmap_page

      Commit:

        b20112edeadf ("perf/x86: Improve accuracy of perf/sched clock")

      allowed the time_shift value in perf_event_mmap_page to be as much
      as 32.  Unfortunately the documented algorithms for using time_shift
      have it shifting an integer, whereas to work correctly with the value
      32, the type must be u64.

      In the case of perf tools, Intel PT decodes correctly but the timestamps
      that are output (for example by perf script) have lost 32-bits of
      granularity so they look like they are not changing at all.

      Fix by limiting the shift to 31 and adjusting the multiplier accordingly.

      Also update the documentation of perf_event_mmap_page so that new code
      based on it will be more future-proof.

      stop_machine: Kill smp_hotplug_thread->pre_unpark, introduce 
stop_machine_unpark()

      1. Change smpboot_unpark_thread() to check ->selfparking, just
         like smpboot_park_thread() does.

      2. Introduce stop_machine_unpark() which sets ->enabled and calls
         kthread_unpark().

      3. Change smpboot_thread_call() and cpu_stop_init() to call
         stop_machine_unpark() by hand.

      This way:

          - IMO the ->selfparking logic becomes more consistent.

          - We can kill the smp_hotplug_thread->pre_unpark() method.

          - We can easily unpark the stopper thread earlier. Say, we
            can move stop_machine_unpark() from smpboot_thread_call()
            to sched_cpu_active() as Peter suggests.

      stop_machine: Change cpu_stop_queue_two_works() to rely on 
stopper->enabled

      Change cpu_stop_queue_two_works() to ensure that both CPU's have
      stopper->enabled == T or fail otherwise.

      This way stop_two_cpus() no longer needs to check cpu_active() to
      avoid the deadlock. This patch doesn't remove these checks, we will
      do this later.

      Note: we need to take both stopper->lock's at the same time, but this
      will also help to remove lglock from stop_machine.c, so I hope this
      is fine.

      stop_machine: Ensure that a queued callback will be called before 
cpu_stop_park()

      cpu_stop_queue_work() checks stopper->enabled before it queues the
      work, but ->enabled == T can only guarantee cpu_stop_signal_done()
      if we race with cpu_down().

      This is not enough for stop_two_cpus() or stop_machine(), they will
      deadlock if multi_cpu_stop() won't be called by one of the target
      CPU's. stop_machine/stop_cpus are fine, they rely on stop_cpus_mutex.
      But stop_two_cpus() has to check cpu_active() to avoid the same race
      with hotplug, and this check is very unobvious and probably not even
      correct if we race with cpu_up().

      Change cpu_down() pass to clear ->enabled before cpu_stopper_thread()
      flushes the pending ->works and returns with KTHREAD_SHOULD_PARK set.

      Note also that smpboot_thread_call() calls cpu_stop_unpark() which
      sets enabled == T at CPU_ONLINE stage, so this CPU can't go away until
      cpu_stopper_thread() is called at least once. This all means that if
      cpu_stop_queue_work() succeeds, we know that work->fn() will be called.

      sched/deadline: Fix migration of SCHED_DEADLINE tasks

      Commit:

        9d5142624256 ("sched/deadline: Reduce rq lock contention by eliminating 
locking of non-feasible target")

      broke select_task_rq_dl() and find_lock_later_rq(), because it introduced
      a comparison between the local task's deadline and dl.earliest_dl.curr of
      the remote queue.

      However, if the remote runqueue does not contain any SCHED_DEADLINE
      task its earliest_dl.curr is 0 (always smaller than the deadline of
      the local task) and the remote runqueue is not selected for pushing.

      As a result, if an application creates multiple SCHED_DEADLINE
      threads, they will never be pushed to runqueues that do not already
      contain SCHED_DEADLINE tasks.

      This patch fixes the issue by checking if dl.dl_nr_running == 0.

      nohz: Revert "nohz: Set isolcpus when nohz_full is set"

      This reverts:

        8cb9764fc88b ("nohz: Set isolcpus when nohz_full is set")

      We assumed that full-nohz users always want scheduler isolation on full
      dynticks CPUs, therefore we included full-nohz CPUs on cpu_isolated_map.

      This means that tasks run by default on CPUs outside the nohz_full range
      unless their affinity is explicity overwritten.

      This suits pure isolation workloads but when the machine is needed to
      run common workloads, the available sets of CPUs to run common tasks
      becomes reduced.

      We reach an extreme case when CONFIG_NO_HZ_FULL_ALL is enabled as it
      leaves only CPU 0 for non-isolation tasks, which makes people think that
      their supercomputer regressed to 90's UP - which is true in a sense.

      Some full-nohz users appear to be interested in running normal workloads
      either before or after an isolation workload. Full-nohz isn't optimized
      toward normal workloads but it's still better than UP performance.

      We are reaching a limitation in kernel presets here. Lets revert this
      cpu_isolated_map inclusion and let userspace do its own scheduler
      isolation using cpusets or explicit affinity settings.

      sched/fair: Update task group's load_avg after task migration

      When cfs_rq has cfs_rq->removed_load_avg set (when a task migrates from
      this cfs_rq), we need to update its contribution to the group's load_avg.

      This should not increase tg's update too much, because in most cases, the
      cfs_rq has already decayed its load_avg.

      sched/fair: Fix overly small weight for interactive group entities

      Commit:

        9d89c257dfb9 ("sched/fair: Rewrite runnable load and utilization 
average tracking")

      led to an overly small weight for interactive group entities. The bad case
      can be easily reproduced when a number of CPU hogs compete for the CPUs
      at the same time (thanks to Mike). This is largly because the task group's
      load average tracking cross CPUs lags behind the real changes.

      To fix this we accelerate the group share distribution process by using
      the load.weight of the cfs_rq. This may increase the entire group's
      share, but we have to do so to protect the (fragile) interactive
      tasks, especially from CPU hogs.

      i40e/i40evf: change dynamic interrupt thresholds

      The dynamic algorithm, while now working, doesn't have good
      performance in 40G mode.

      One part of this patch addresses the high CPU utilization of some small
      streaming workloads that the driver should reduce CPU in.

      It also changes the minimum ITR that the dynamic algorithm
      will settle on, causing our minimum latency to go from 12us
      to about 14us, when using adaptive mode.

      It also changes the BULK interrupt rate to allow maximum throughput
      on a 40Gb connection with a single thread of transmit, clamping
      interrupt rate to 8000 for TX makes single thread traffic go too
      slow.

      The new ULTRA bulk setting is introduced and is used
      when the Rx packet rate on this queue exceeds 40000 packets per
      second.  This value of 40000 was chosen because the automatic tuning
      of minimum ITR=20us means that a single queue can't quite achieve
      that many packets per second from a round-robin test.

      i40e/i40evf: refactor IRQ enable function

      This change moves a multi-line register setting into a function
      which simplifies reading the flow of the enable function.

      This also fixes a bug where the enable function was enabling
      the interrupt twice while trying to update the two interrupt
      throttle rate thresholds for Rx and Tx.

      i40evf: don't give up

      When the VF driver is unable to communicate with the PF, it just gives
      up and never tries again. Aside from the obvious character flaw that
      this shows, it's also a lousy user experience.

      When PF communications fail, wait five seconds, and try again. And
      again. Don't give up, little VF driver! Your prince will come!

      i40e: Fix basic support for X722 devices

      Acquire NVM, before issuing an AQ read nvm command for X722.
      We need to acquire the NVM before issuing an AQ read to the NVM
      otherwise we will get EBUSY from the FW. Also release when done.

      This fixes the two X722 issues with respect to eeprom checksum verify
      and reading NVM version info.

      With this patch in place, i40e driver will provide basic support
      for X722 devices.

      i40e: Lock for VSI's MAC filter list

      This patch introduces a spinlock which is to be used for synchronizing
      access to VSI's MAC filter list.

      This patch also synchronizes execution of other codepaths which are
      accessing VSI's MAC filter list with execution of
      service_task:sync_vsi_filters.

      In function i40e_add_vsi, copied out LAA MAC address instead of cloning
      MAC filter entry because only MAC address is needed to remove MAC VLAN
      filter from FW/HW.

      If UML is executing a helper program it is using
      waitpid() with the __WCLONE flag to wait for the program
      as the helper is executed from a clone()'ed thread.
      While using __WCLONE is perfectly fine for clone()'ed
      childs it won't detect terminated childs if the helper
      has issued an execve().

      We have to use __WALL to wait for both clone()'ed and
      regular childs to detect the termination before and
      after an execve().

      modify_ldt() was declared as an external symbol. Despite the man

      since version 2.1 there actually is, so linking to the glibc
      works.

      Since modify_ldt() is not a POSIX interface, other libc
      implementations do not always provide a wrapper function.
      Even glibc headers do not provide a corresponding declaration.

      So go the recommended way to call this using syscall().

      saving 180ms on the boot time of the kernel (which is around 10%).

      It also means that udelay() will be unaffected by CPU frequency changes

      perf bench: Harmonize all the -l/--nr_loops options

      We have three benchmarking subsystems that specify some sort of 'number
      of loops' parameter - but all of them do it inconsistently:

       numa:              -l/--nr_loops
       sched messaging:   -l/--loops
       mem memset/memcpy: -i/--iterations

      Harmonize them to -l/--nr_loops by picking the numa variant - which is
      also the most likely one to have existing scripting which we don't want
      to break.

      Plus improve the parameter help texts to indicate the default value for
      the nr_loops variable to keep users from guessing ...

      Also propagate the naming to internal variables.

      perf bench mem: Reorganize the code a bit

      Reorder functions a bit, so that we synchronize the layout of the
      memcpy() and memset() portions of the code.

      This improves the code, especially after we'll add an strlcpy() variant
      as well.

      perf bench: Remove the prefaulting complication from 'perf bench mem mem*'

      So 'perf bench mem memcpy/memset' has elaborate code to measure
      memcpy()/memset() performance both with freshly allocated buffers (which
      includes initial page fault overhead) and with preallocated buffers.

      But the thing is, the resulting bandwidth results are mostly
      meaningless, because page faults dominate so much of the cost.

      It might make sense to measure cache cold vs. cache hot performance, but
      the code does not do this.

      So remove this complication, and always prefault the ranges before using
      them.

      perf bench: Default to all routines in 'perf bench mem'

      So few people know that the --routine option to 'perf bench memcpy/memset'
      exists, and would not know that it's capable of testing the kernel's
      memcpy/memset implementations.

      Furthermore, 'perf bench mem all' will not run all routines:

        vega:~> perf bench mem all
        # Running mem/memcpy benchmark...
        Routine default (Default memcpy() provided by glibc)
        # Copying 1MB Bytes ...

             894.454383 MB/Sec
               3.844734 GB/Sec (with prefault)

        # Running mem/memset benchmark...
        Routine default (Default memset() provided by glibc)
        # Copying 1MB Bytes ...

               1.220703 GB/Sec
               9.042245 GB/Sec (with prefault)

      Because misleadingly the 'all' refers to 'all sub-benchmarks', not 'all
      sub-benchmarks and routines'.

      Fix all this by making the memcpy/memset routine to default to 'all',
      which results in all the benchmarks being run:

        triton:~> perf bench mem all
        # Running mem/memcpy benchmark...

      perf test: Suppress libtraceevent warnings

      Currently libtraceevent emits warning on unsupported event formats.
      However it'd be better to see them only -v option is given.  To do that,
      it needs to override the warning() function which is used in the
      libtracevent.  Thus add set_warning_routine() same as set_die_routine()
      and check the verbose flag in our warning routine.

      Before:
        # perf test 5
         5: parse events tests                                       :
          Warning: [kvmmmu:kvm_mmu_get_page] bad op token {
          Warning: [kvmmmu:kvm_mmu_sync_page] bad op token {
          Warning: [kvmmmu:kvm_mmu_unsync_page] bad op token {
          Warning: [kvmmmu:kvm_mmu_prepare_zap_page] bad op token {
          Warning: [kvmmmu:fast_page_fault] function is_writable_pte not defined
          ...

      perf test: Silence tracepoint event failures

      Currently, when 'perf test' is run by a normal user, it'll fail to
      access tracepoint events.  The output becomes somewhat messy because it
      tries to be nice with long error messages and hints.

      IMHO this is not needed for 'perf test' by default and AFAIK 'perf test'
      uses pr_debug() rather than pr_err() for such messages so that one can
      use -v option to see further details on failed testcases if needed.

      Before:
        $ perf test

      NFC: pn544: Auto-select core module

      As I understand it, the core nfc_pn544 module is useless without
      either the I2C or the MEI access module. So hide NFC_PN544 and
      select it automatically if either NFC_PN544_I2C or NFC_PN544_MEI is
      selected.

      This avoids presenting NFC_PN544 when neither NFC_PN544_I2C nor
      NFC_PN544_MEI can be selected.

      arm64: Synchronise dump_backtrace() with perf callchain

      Unlike perf callchain relying on walk_stackframe(), dump_backtrace()
      has its own backtrace logic. A major difference between them is the
      moment a symbol is recorded. Perf writes down a symbol *before*
      calling unwind_frame(), but dump_backtrace() prints it out *after*
      unwind_frame(). As a result, the last valid symbol cannot be hooked
      in case of dump_backtrace(). This patch addresses the issue as
      synchronising dump_backtrace() with perf callchain.

      A simple test and its results are as follows:

      - crash trigger

       $ sudo echo c > /proc/sysrq-trigger

      - current status

       Call trace:
       [<fffffe00003dc738>] sysrq_handle_crash+0x24/0x30
       [<fffffe00003dd2ac>] __handle_sysrq+0x128/0x19c
       [<fffffe00003dd730>] write_sysrq_trigger+0x60/0x74
       [<fffffe0000249fc4>] proc_reg_write+0x84/0xc0
       [<fffffe00001f2638>] __vfs_write+0x44/0x104
       [<fffffe00001f2e60>] vfs_write+0x98/0x1a8
       [<fffffe00001f3730>] SyS_write+0x50/0xb0

      - with this change

       Call trace:
       [<fffffe00003dc738>] sysrq_handle_crash+0x24/0x30
       [<fffffe00003dd2ac>] __handle_sysrq+0x128/0x19c
       [<fffffe00003dd730>] write_sysrq_trigger+0x60/0x74
       [<fffffe0000249fc4>] proc_reg_write+0x84/0xc0
       [<fffffe00001f2638>] __vfs_write+0x44/0x104

       [<fffffe00000939ec>] el0_svc_naked+0x20/0x28

      Note that this patch does not cover a case where MMU is disabled. The
      last stack frame of swapper, for example, has PC in a form of physical
      address. Unfortunately, a simple conversion using phys_to_virt() cannot
      cover all scenarios since PC is retrieved from LR - 4, not LR. It is
      a big tradeoff to change both head.S and unwind_frame() for only a few
      of symbols in *.S. Thus, this hunk does not take care of the case.

      This patch turns on the 16K page support in the kernel. We
      support 48bit VA (4 level page tables) and 47bit VA (3 level

      With 16K we can map 128 entries using contiguous bit hint
      at level 3 to map 2M using single TLB entry.

      TODO: 16K supports 32 contiguous entries at level 2 to get us
      1G(which is not yet supported by the infrastructure). That should
      be a separate patch altogether.

      arm64: Introduce helpers for page table levels

      Introduce helpers for finding the number of page table
      levels required for a given VA width, shift for a particular
      page table level.

      Convert the existing users to the new helpers. More users

      arm64: Handle section maps for swapper/idmap

      We use section maps with 4K page size to create the swapper/idmaps.
      So far we have used !64K or 4K checks to handle the case where we
      use the section maps.
      This patch adds a new symbol, ARM64_SWAPPER_USES_SECTION_MAPS, to
      handle cases where we use section maps, instead of using the page size
      symbols.

      arm64: Move swapper pagetable definitions

      Move the kernel pagetable (both swapper and idmap) definitions
      from the generic asm/page.h to a new file, asm/kernel-pgtable.h.

      This is mostly a cosmetic change, to clean up the asm/page.h to
      get rid of the arch specific details which are not needed by the
      generic code.

      Also renames the symbols to prevent conflicts. e.g,
        BLOCK_SHIFT => SWAPPER_BLOCK_SHIFT

      ARM: 8447/1: catch pending imprecise abort on unmask

      Install a non-faulting handler just before unmasking imprecise aborts
      and switch back to the regular one after unmasking is done.

      This catches any pending imprecise abort that the firmware/bootloader
      may have left behind that would normally crash the kernel at that point.
      As there are apparently a lot of bootlaoders out there that do such a
      thing it makes sense to handle it in the common startup code.

      ARM: OMAP2+: Fix imprecise external abort caused by bogus SRAM init

      Some omaps are producing imprecise external aborts because we are
      wrongly trying to init SRAM for device tree based booting. Only
      omap3 is still using the legacy SRAM code, so we need to make it
      omap3 specific. Otherwise we can get errors like this on at least
      dm814x:

      Unhandled fault: imprecise external abort (0xc06) at 0xc08b156c
      ...

      Let's fix the issue by making sure omap_sdrc_init only gets called for
      omap3. To do that, we need to have compatible "ti,omap3" in the dts
      files. And let's also use "ti,omap3630" instead of "ti,omap36xx" like
      we're supposed to.

      ath10k: disable PCI PS for QCA988X and QCA99X0

      This patch disables PCI PS for QCA988X and QCA99X0, Since PCI PS is
      validated for QCA6174, let it be enabled only for QCA6174. It would be
      better to execute PCI PS related functions only for the supported devices.

      PCI time out issue is observed with QCA99X0 on x86 platform, We will
      disable PCI PS for QCA988X and QCA99X0 until PCI PS is properly 
implemented.

      Taking and releasing ps_lock is causing higher CPU consumption. Michal 
Kazior
      suggested ps_lock overhead to be reworked so that ath10k_pci_wake/sleep
      functions are called less often, i.e. move the powersave logic up (only 
during
      irq handling, tx path, submitting fw commands) but that's a bigger change 
and
      can be implemented later.

      As a reault, the local error handler is not called and the

      We fix this by setting skb->protocol on message size errors

      x86/smpboot: Fix CPU #1 boot timeout

      The following commit:

        a9bcaa02a5104ac ("x86/smpboot: Remove SIPI delays from cpu_up()")

      Caused some Intel Core2 processors to time-out when bringing up CPU #1,
      resulting in the missing of that CPU after bootup.

      That patch reduced the SIPI delays from udelay() 300, 200 to udelay() 0,
      0 on modern processors.

      Several Intel(R) Core(TM)2 systems failed to bring up CPU #1 10/10 times
      after that change.

      Increasing either of the SIPI delays to udelay(1) results in
      success. So here we increase both to udelay(10).  While this may
      be 20x slower than the absolute minimum, it is still 20x to 30x
      faster than the original code.

      x86/smpboot: Fix cpu_init_udelay=10000 corner case boot parameter 
misbehavior

      For legacy machines cpu_init_udelay defaults to 10,000.
      For modern machines it is set to 0.

      The user should be able to set cpu_init_udelay to
      any value on the cmdline, including 10,000.

      Before this patch, that was seen as "unchanged from default"
      and thus on a modern machine, the user request was ignored
      and the delay was set to 0.

      net: bcmgenet: Fix early link interrupt enabling

      Link interrupts are enabled in init_umac(), which is too early for us to
      process them since we do not yet have a valid PHY device pointer. On
      BCM7425 chips for instance, we will crash calling phy_mac_interrupt()
      because phydev is NULL.

      Fix this by moving the link interrupts enabling in
      bcmgenet_netif_start(), under a specific function:
      bcmgenet_link_intr_enable() and while at it, update the comments
      surrounding the code.

      Netfilter/IPVS updates for net-next

      The following patchset contains Netfilter/IPVS updates for your net-next
      tree. Most relevantly, updates for the nfnetlink_log to integrate with
      conntrack, fixes for cttimeout and improvements for nf_queue core, they 
are:

      1) Remove useless ifdef around static inline function in IPVS, from
         Eric W. Biederman.

      2) Simplify the conntrack support for nfnetlink_queue: Merge
         nfnetlink_queue_ct.c file into nfnetlink_queue_core.c, then rename it 
back
         to nfnetlink_queue.c

      3) Use y2038 safe timestamp from nfnetlink_queue.

      4) Get rid of dead function definition in nf_conntrack, from Flavio
         Leitner.

      5) Attach conntrack support for nfnetlink_log.c, from Ken-ichirou 
MATSUZAWA.
         This adds a new NETFILTER_NETLINK_GLUE_CT Kconfig switch that
         controls enabling both nfqueue and nflog integration with conntrack.
         The userspace application can request this via NFULNL_CFG_F_CONNTRACK
         configuration flag.

      6) Remove unused netns variables in IPVS, from Eric W. Biederman and
         Simon Horman.

      7) Don't put back the refcount on the cttimeout object from xt_CT on 
success.

      8) Fix crash on cttimeout policy object removal. We have to flush out
         the cttimeout extension area of the conntrack not to refer to an 
unexisting
         object that was just removed.

      9) Make sure rcu_callback completion before removing nfnetlink_cttimeout
         module removal.

      10) Fix compilation warning in br_netfilter when no nf_defrag_ipv4 and
          nf_defrag_ipv6 are enabled. Patch from Arnd Bergmann.

      11) Autoload ctnetlink dependencies when NFULNL_CFG_F_CONNTRACK is
          requested. Again from Ken-ichirou MATSUZAWA.

      12) Don't use pointer to previous hook when reinjecting traffic via
          nf_queue with NF_REPEAT verdict since it may be already gone. This
          also avoids a deadloop if the userspace application keeps returning
          NF_REPEAT.

      13) A bunch of cleanups for netfilter IPv4 and IPv6 code from Ian Morris.

      14) Consolidate logger instance existence check in nfulnl_recv_config().

      15) Fix broken atomicity when applying configuration updates to logger
          instances in nfnetlink_log.

      16) Get rid of the .owner attribute in our hook object. We don't need
          this anymore since we're dropping pending packets that have escaped
          from the kernel when unremoving the hook. Patch from Florian Westphal.

      17) Remove unnecessary rcu_read_lock() from nf_reinject code, we always
          assume RCU read side lock from .call_rcu in nfnetlink. Also from 
Florian.

      18) Use static inline function instead of macros to define NF_HOOK() and
          NF_HOOK_COND() when no netfilter support in on, from Arnd Bergmann.

      RDS: fix rds-ping deadlock over TCP transport

      Sowmini found hang with rds-ping while testing RDS over TCP. Its
      a corner case and doesn't happen always. The issue is not reproducible
      with IB transport. Its clear from below dump why we see it with RDS TCP.

       [<ffffffff8152e0b3>] ip_local_deliver_finish+0xa3/0x220

      This happens because rds_send_xmit() chain wants to take
      sock_lock which is already taken by tcp_v4_rcv() on its
      way to rds_tcp_data_ready(). Commit db6526dcb51b ("RDS: use
      rds_send_xmit() state instead of RDS_LL_SEND_FULL") which
      was trying to opportunistically finish the send request
      in same thread context.

      But because of above recursive lock hang with RDS TCP,
      the send work from rds_send_pong() needs to deferred to
      worker to avoid lock up. Given RDS ping is more of connectivity
      test than performance critical path, its should be ok even
      for transport like IB.

      tunnels: Don't require remote endpoint or ID during creation.

      Before lightweight tunnels existed, it really didn't make sense to
      create a tunnel that was not fully specified, such as without a
      destination IP address - the resulting packets would go nowhere.
      However, with lightweight tunnels, the opposite is true - it doesn't
      make sense to require this information when it will be provided later
      on by the route. This loosens the requirements for this information.

      An alternative would be to allow the relaxed version only when
      COLLECT_METADATA is enabled. However, since there are several
      variations on this theme (such as NBMA tunnels in GRE), just dropping
      the restrictions seems the most consistent across tunnels and with
      the existing configuration.

      tcp: do not set queue_mapping on SYNACK

      At the time of commit fff326990789 ("tcp: reflect SYN queue_mapping into
      SYNACK packets") we had little ways to cope with SYN floods.

      We no longer need to reflect incoming skb queue mappings, and instead
      can pick a TX queue based on cpu cooking the SYNACK, with normal XPS
      affinities.

      Note that all SYNACK retransmits were picking TX queue 0, this no longer
      is a win given that SYNACK rtx are now distributed on all cpus.

      openvswitch: Scrub skb between namespaces

      If OVS receives a packet from another namespace, then the packet should
      be scrubbed. However, people have already begun to rely on the behaviour
      that skb->mark is preserved across namespaces, so retain this one field.

      This is mainly to address information leakage between namespaces when
      using OVS internal ports, but by placing it in ovs_vport_receive() it is
      more generally applicable, meaning it should not be overlooked if other
      port types are allowed to be moved into namespaces in future.

      pull request: bluetooth 2015-10-16

      First of all, sorry for the late set of patches for the 4.3 cycle. We
      just finished an intensive week of testing at the Bluetooth UnPlugFest
      and discovered (and fixed) issues there. Unfortunately a few issues
      affect 4.3-rc5 in a way that they break existing Bluetooth LE mouse and
      keyboard support.

      The regressions result from supporting LE privacy in conjunction with
      scanning for Resolvable Private Addresses before connecting. A feature
      that has been tested heavily (including automated unit tests), but sadly
      some regressions slipped in. The UnPlugFest with its multitude of test
      platforms is a good battle testing ground for uncovering every corner
      case.

      The patches in this pull request focus only on fixing the regressions in
      4.3-rc5. The patches look a bit larger since we also added comments in
      the critical sections of the fixes to improve clarity.

      I would appreciate if we can get these regression fixes to Linus
      quickly. Please let me know if there are any issues pulling. Thanks.

      net: hix5hd2_gmac: avoid integer overload warning

      BITS_RX_EN is an 'unsigned long' constant, so the ones complement of that
      has bits set that do not fit into a 32-bit variable on 64-bit 
architectures,
      which causes a harmless gcc warning:

      drivers/net/ethernet/hisilicon/hix5hd2_gmac.c: In function 
'hix5hd2_port_disable':
      drivers/net/ethernet/hisilicon/hix5hd2_gmac.c:374:2: warning: large 
integer implicitly truncated to unsigned type [-Woverflow]
        writel_relaxed(~(BITS_RX_EN | BITS_TX_EN), priv->base + PORT_EN);

      This adds a cast to (u32) to tell gcc that the code is indeed fine.

      net: hisilicon: add OF dependency

      The HNS MDIO driver fails to build on older ARM machines that are not
      yet converted to CONFIG_OF:

      drivers/net/ethernet/hisilicon/hns_mdio.c: In function 
'hns_mdio_bus_name':
      drivers/net/ethernet/hisilicon/hns_mdio.c:405:14: error: 'OF_BAD_ADDR' 
undeclared (first use in this function)
        u64 taddr = OF_BAD_ADDR;

      drivers/net/ethernet/hisilicon/hns_mdio.c:405:14: note: each undeclared

         taddr = of_translate_address(np, addr);
                 ^

      This clarifies the dependency to ensure we don't attempt to build these
      drivers without CONFIG_OF, but also adds a COMPILE_TEST alternative to
      give us better build coverage testing.

      Build-tested on x86 as well to ensure this actually works.

      this patch fixes the bug triggered timeout sequence. when the connective
      ports cannot accept the packets with higher speed, they will send out the
      pause frame to the Soc's mac. At that time, the driver resets the relevant
      of the Soc, then it causes the packets cannot be sent out immediately.

      netlink: Trim skb to alloc size to avoid MSG_TRUNC

      netlink_dump() allocates skb based on the calculated min_dump_alloc or
      a per socket max_recvmsg_len.
      min_alloc_size is maximum space required for any single netdev
      attributes as calculated by rtnl_calcit().
      max_recvmsg_len tracks the user provided buffer to netlink_recvmsg.
      It is capped at 16KiB.
      The intention is to avoid small allocations and to minimize the number
      of calls required to obtain dump information for all net devices.

      netlink_dump packs as many small messages as could fit within an skb
      that was sized for the largest single netdev information. The actual
      space available within an skb is larger than what is requested. It could
      be much larger and up to near 2x with align to next power of 2 approach.

      Allowing netlink_dump to use all the space available within the
      allocated skb increases the buffer size a user has to provide to avoid
      truncaion (i.e. MSG_TRUNG flag set).

      It was observed that with many VLANs configured on at least one netdev,
      a larger buffer of near 64KiB was necessary to avoid "Message truncated"
      error in "ip link" or "bridge [-c[ompressvlans]] vlan show" when
      min_alloc_size was only little over 32KiB.

      This patch trims skb to allocated size in order to allow the user to
      avoid truncation with more reasonable buffer size.

      ipconfig: send Client-identifier in DHCP requests

      A dhcp server may provide parameters to a client from a pool of IP
      addresses and using a shared rootfs, or provide a specific set of
      parameters for a specific client, usually using the MAC address to
      identify each client individually. The dhcp protocol also specifies
      a client-id field which can be used to determine the correct
      parameters to supply when no MAC address is available. There is
      currently no way to tell the kernel to supply a specific client-id,
      only the userspace dhcp clients support this feature, but this can
      not be used when the network is needed before userspace is available
      such as when the root filesystem is on NFS.

      This patch is to be able to do something like "ip=dhcp,client_id_type,
      client_id_value", as a kernel parameter to enable the kernel to
      identify itself to the server.

      i2c: designware: Do not use parameters from ACPI on Dell Inspiron 7348

      ACPI SSCN/FMCN methods were originally added because then the platform can
      provide the most accurate HCNT/LCNT values to the driver. However, this
      seems not to be true for Dell Inspiron 7348 where using these causes the
      touchpad to fail in boot:

        i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
        i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration
        i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
        i2c_designware INT3433:00: controller timed out

      The values received from ACPI are (in fast mode):

        HCNT: 72
        LCNT: 160

      this translates to following timings (input clock is 100MHz on Broadwell):

        tHIGH: 720 ns (spec min 600 ns)
        tLOW: 1600 ns (spec min 1300 ns)
        Bus period: 2920 ns (assuming 300 ns tf and tr)
        Bus speed: 342.5 kHz

      Both tHIGH and tLOW are within the I2C specification.

      The calculated values when ACPI parameters are not used are (in fast 
mode):

        HCNT: 87
        LCNT: 159

      which translates to:

        tHIGH: 870 ns (spec min 600 ns)
        tLOW: 1590 ns (spec min 1300 ns)
        Bus period 3060 ns (assuming 300 ns tf and tr)
        Bus speed 326.8 kHz

      These values are also within the I2C specification.

      Since both ACPI and calculated values meet the I2C specification timing
      requirements it is hard to say why the touchpad does not function properly
      with the ACPI values except that the bus speed is higher in this case (but
      still well below the max 400kHz).

      Solve this by adding DMI quirk to the driver that disables using ACPI
      parameters on this particulare machine.

      ARC: [arcompact] entry.S: Improve early return from exception

      The requirement is to
       - Reenable Exceptions (AE cleared)
       - Reenable Interrupts (E1/E2 set)

      We need to do wiggle these bits into ERSTATUS and call RTIE.

      Prev version used the pre-exception STATUS32 as starting point for what
      goes into ERSTATUS. This required explicit fixups of U/DE/L bits.

      Instead, use the current (in-exception) STATUS32 as starting point.
      Being in exception handler U/DE/L can be safely assumed to be correct.
      Only AE/E1/E2 need to be fixed.

      So the new implementation is slightly better
       -Avoids read form memory
       -Is 4 bytes smaller for the typical 1 level of intr configuration
       -Depicts the semantics more clearly

      ARC: [arcompact] don't check for hard isr calling local_irq_enable()

      Historically this was done by ARC IDE driver, which is long gone.
      IRQ core is pretty robust now and already checks if IRQs are enabled
      in hard ISRs. Thus no point in checking this in arch code, for every
      call of irq enabled.

      Further if some driver does do that - let it bring down the system so we
      notice/fix this sooner than covering up for sucker

      This makes local_irq_enable() - for L1 only case atleast simple enough
      so we can inline it.

      mm,thp: introduce flush_pmd_tlb_range

      ARCHes with special requirements for evicting THP backing TLB entries
      can implement this.

      Otherwise also, it can help optimize TLB flush in THP regime.
      stock flush_tlb_range() typically has optimization to nuke the entire
      TLB if flush span is greater than a certain threshhold, which will
      likely be true for a single huge page. Thus a single thp flush will
      invalidate the entrire TLB which is not desirable.

      ARCv2: mm: THP support

      MMUv4 in HS38x cores supports Super Pages which are basis for Linux THP
      support.

      Normal and Super pages can co-exist (ofcourse not overlap) in TLB with a
      new bit "SZ" in TLB page desciptor to distinguish between them.
      Super Page size is configurable in hardware (4K to 16M), but fixed once
      RTL builds.

      The exact THP size a Linx configuration will support is a function of:
       - MMU page size (typical 8K, RTL fixed)
       - software page walker address split between PGD:PTE:PFN (typical
         11:8:13, but can be changed with 1 line)

      So for above default, THP size supported is 8K * 256 = 2M

      Default Page Walker is 2 levels, PGD:PTE:PFN, which in THP regime
      reduces to 1 level (as PTE is folded into PGD and canonically referred
      to as PMD).

      Thus thp PMD accessors are implemented in terms of PTE (just like sparc)

      net: add pfmemalloc check in sk_add_backlog()

      Greg reported crashes hitting the following check in __sk_backlog_rcv()

        BUG_ON(!sock_flag(sk, SOCK_MEMALLOC));

      The pfmemalloc bit is currently checked in sk_filter().

      This works correctly for TCP, because sk_filter() is ran in
      tcp_v[46]_rcv() before hitting the prequeue or backlog checks.

      For UDP or other protocols, this does not work, because the sk_filter()
      is ran from sock_queue_rcv_skb(), which might be called _after_ backlog
      queuing if socket is owned by user by the time packet is processed by
      softirq handler.

      netfilter: ipset: Fix sleeping memory allocation in atomic context

      Commit 00590fdd5be0 introduced RCU locking in list type and in
      doing so introduced a memory allocation in list_set_add, which
      is done in an atomic context, due to the fact that ipset rcu
      list modifications are serialised with a spin lock. The reason
      why we can't use a mutex is that in addition to modifying the
      list with ipset commands, it's also being modified when a
      particular ipset rule timeout expires aka garbage collection.
      This gc is triggered from set_cleanup_entries, which in turn
      is invoked from a timer thus requiring the lock to be bh-safe.

      Concretely the following call chain can lead to "sleeping function
      called in atomic context" splat:
      call_ad -> list_set_uadt -> list_set_uadd -> kzalloc(, GFP_KERNEL).
      And since GFP_KERNEL allows initiating direct reclaim thus
      potentially sleeping in the allocation path.

      To fix the issue change the allocation type to GFP_ATOMIC, to
      correctly reflect that it is occuring in an atomic context.

      xhci: Add spurious wakeup quirk for LynxPoint-LP controllers

      We received several reports of systems rebooting and powering on
      after an attempted shutdown. Testing showed that setting
      XHCI_SPURIOUS_WAKEUP quirk in addition to the XHCI_SPURIOUS_REBOOT
      quirk allowed the system to shutdown as expected for LynxPoint-LP
      xHCI controllers. Set the quirk back.

      Note that the quirk was originally introduced for LynxPoint and
      LynxPoint-LP just for this same reason. See:

      commit 638298dc66ea ("xhci: Fix spurious wakeups after S5 on Haswell")

      It was later limited to only concern HP machines as it caused
      regression on some machines, see both bug and commit:

      Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=66171
      commit 6962d914f317 ("xhci: Limit the spurious wakeup fix only to HP 
machines")

      Later it was discovered that the powering on after shutdown
      was limited to LynxPoint-LP (Haswell-ULT) and that some non-LP HP
      machine suffered from spontaneous resume from S3 (which should
      not be related to the SPURIOUS_WAKEUP quirk at all). An attempt
      to fix this then removed the SPURIOUS_WAKEUP flag usage completely.

      commit b45abacde3d5 ("xhci: no switching back on non-ULT Haswell")

      Current understanding is that LynxPoint-LP (Haswell ULT) machines
      need the SPURIOUS_WAKEUP quirk, otherwise they will restart, and
      plain Lynxpoint (Haswell) machines may _not_ have the quirk
      set otherwise they again will restart.

      When requesting a GPIO through the legacy or the gpiod_* API the
      gpiochip request operation is first called and then the GPIO flags are
      parsed and the GPIO is configured. This prevents the gpiochip from
      rejecting the request if the flags are not supported by the device.

      To fix this split the parse-and-configure operation in two and parse
      flags before requesting the GPIO.

      gpio: pl061: use the generic request/free implementations

      Instead of storing in the chip data whether the chip uses pinctrl and
      conditionally call pinctrl_{request,free}_gpio, just don't populate
      request/free in that case.

      This makes the implementations trivial and the same as the generic
      implementations, thus we can just use them.

      pinctrl: atlas7: support atlas7 step B changes

      The the pin groups and pin functions have been changed
      in atlas7 step B soc. We have to update the driver
      to support step B chip.

      Changes:
      1. add 5 jtag pins to IOC_TOP:
        "jtag_tdo", "jtag_tms","jtag_tck", "jtag_tdi", "jtag_trstn"
        these 5 pins can be mutiplex with other functions, so we
        have to conver these 5 pins in pinmux.
      2. add pin groups for audio digmic, audio spdif, can transceiver
        en, can transceiver stb, i2s0, i2s1 and jtag.
      3. serval pins can be located to more PADs:
        audio_uart0_urfs, audio_uart1_urfs, audio_uart2_urfs,
        audio_uart2_urxd, audio_uart2_usclk, audio_uart2_utfs,
        audio_uart2_utxd, can0_rxd, can0_txd, can1_rxd, can1_txd
        jtag_ntrst, jtag_swdiotms, jtag_tck, jtag_tdi, jtag_tdo,
        pw_cko0, pw_cko1, pw_i2s01, pw_pwm0, pw_pwm1, sd2_cdb,
        sd2_wpb, uart2_cts, uart2_rts, uart2_rxd, uart2_txd,
        uart3_cts, uart3_rts, uart3_rxd, uart3_txd, uart4_cts,
        uart4_rts, usb0_drvvbus, usb1_drvvbus.

      Because of Changes#3, some functions should have more than one
      pin groups. So we have to split the original pin group to serval
      pin groups.

      For example:
      audio_uart0 has 5 pins, on STEPA, each of these 5 pins only has
      one related PAD. But on STEPB, audio_uart0_urfs has 4 related
      PAD.
      So we place the 4 pins with one PAD into a single pin group:
        audio_uart0_basic_group.
      and place urfs pin wtih different PADs to 4 different pin groups:
        audio_uart0_urfs_group0, ..., audio_uart0_urfs_group3

      A full audio_uart0 pin group can be:
        pinctrl-0 = <&audio_uart0_basic_group &audio_uart0_urfs_group0>;
      If audio_uart0 pin group encountered some confiction, we only have
      to change the urfs group:
        pinctrl-0 = <&audio_uart0_basic_group &audio_uart0_urfs_group2>;

      mm, dax: fix DAX deadlocks

      The following two locking commits in the DAX code:

      commit 843172978bb9 ("dax: fix race between simultaneous faults")
      commit 46c043ede471 ("mm: take i_mmap_lock in unmap_mapping_range() for 
DAX")

      introduced a number of deadlocks and other issues which need to be fixed
      for the v4.3 kernel.  The list of issues in DAX after these commits
      (some newly introduced by the commits, some preexisting) can be found
      here:

        https://lkml.org/lkml/2015/9/25/602 (Subject: "Re: [PATCH] dax: fix 
deadlock in __dax_fault").

      This undoes most of the changes introduced by those two commits,
      essentially returning us to the DAX locking scheme that was used in
      v4.2.

      builddeb: remove debian/files before build

      Commit 3716001bcb7f ("deb-pkg: add source package") added the ability to
      create a debian changelog file.  This exposed that previously the
      builddeb script hasn't cleared debian/files between builds.

      As debian/files keeps accumulating entries, the changes file will end up
      growing indefinelty.  With outdated entries in debian/files, builddeb
      script will exit with failure.  This regression impacts those who use
      "make deb-pkg" target to build kernel into a .deb package and never use
      "make mrproper" or other means to clean kernel tree from generated
      directories.

      To fix the regression, remove debian/files before starting build and in
      the generated clean rule.

      mm, fs: obey gfp_mapping for add_to_page_cache()

      Commit 6afdb859b710 ("mm: do not ignore mapping_gfp_mask in page cache
      allocation paths") has caught some users of hardcoded GFP_KERNEL used in
      the page cache allocation paths.  This, however, wasn't complete and
      there were others which went unnoticed.

      Dave Chinner has reported the following deadlock for xfs on loop device:
      : With the recent merge of the loop device changes, I'm now seeing
      : XFS deadlock on my single CPU, 1GB RAM VM running xfs/073.
      :
      : The deadlocked is as follows:
      :
      : kloopd1: loop_queue_read_work
      :       xfs_file_iter_read
      :       lock XFS inode XFS_IOLOCK_SHARED (on image file)
      :       page cache read (GFP_KERNEL)
      :       radix tree alloc
      :       memory reclaim
      :       reclaim XFS inodes
      :       log force to unpin inodes
      :       <wait for log IO completion>
      :
      : xfs-cil/loop1: <does log force IO work>
      :       xlog_cil_push
      :       xlog_write
      :       <loop issuing log writes>
      :               xlog_state_get_iclog_space()
      :               <blocks due to all log buffers under write io>
      :               <waits for IO completion>
      :
      : kloopd1: loop_queue_write_work
      :       xfs_file_write_iter
      :       lock XFS inode XFS_IOLOCK_EXCL (on image file)
      :       <wait for inode to be unlocked>
      :
      : i.e. the kloopd, with it's split read and write work queues, has
      : introduced a dependency through memory reclaim. i.e. that writes
      : need to be able to progress for reads make progress.
      :
      : The problem, fundamentally, is that mpage_readpages() does a
      : GFP_KERNEL allocation, rather than paying attention to the inode's
      : mapping gfp mask, which is set to GFP_NOFS.
      :
      : The didn't used to happen, because the loop device used to issue
      : reads through the splice path and that does:
      :
      :       error = add_to_page_cache_lru(page, mapping, index,
      :                       GFP_KERNEL & mapping_gfp_mask(mapping));

      This has changed by commit aa4d86163e4 ("block: loop: switch to VFS
      ITER_BVEC").

      This patch changes mpage_readpage{s} to follow gfp mask set for the
      mapping.  There are, however, other places which are doing basically the
      same.

      lustre:ll_dir_filler is doing GFP_KERNEL from the function which
      apparently uses GFP_NOFS for other allocations so let's make this
      consistent.

      cifs:readpages_get_pages is called from cifs_readpages and
      __cifs_readpages_from_fscache called from the same path obeys mapping
      gfp.

      ramfs_nommu_expand_for_mapping is hardcoding GFP_KERNEL as well
      regardless it uses mapping_gfp_mask for the page allocation.

      ext4_mpage_readpages is the called from the page cache allocation path
      same as read_pages and read_cache_pages

      As I've noticed in my previous post I cannot say I would be happy about
      sprinkling mapping_gfp_mask all over the place and it sounds like we
      should drop gfp_mask argument altogether and use it internally in
      __add_to_page_cache_locked that would require all the filesystems to use
      mapping gfp consistently which I am not sure is the case here.  From a
      quick glance it seems that some file system use it all the time while
      others are selective.

      netfilter: turn NF_HOOK into an inline function

      A recent change to the dst_output handling caused a new warning
      when the call to NF_HOOK() is the only used of a local variable
      passed as 'dev', and CONFIG_NETFILTER is disabled:

      net/ipv6/ip6_output.c: In function 'ip6_output':
      net/ipv6/ip6_output.c:135:21: warning: unused variable 'dev' 
[-Wunused-variable]

      The reason for this is that the NF_HOOK macro in this case does
      not reference the variable at all, and the call to dev_net(dev)
      got removed from the ip6_output function. To avoid that warning now
      and in the future, this changes the macro into an equivalent
      inline function, which tells the compiler that the variable is
      passed correctly but still unused.

      The dn_forward function apparently had the same problem in
      the past and added a local workaround that no longer works
      with the inline function. In order to avoid a regression, we
      have to also remove the #ifdef from decnet in the same patch.

      ASoC: Add info callback for SX_TLV controls

      SX_TLV controls are intended for situations where the register behind
      the control has some non-zero value indicating the minimum gain
      and then gains increasing from there and eventually overflowing through
      zero.

      Currently every CODEC implementing these controls specifies the minimum
      as the non-zero value for the minimum and the maximum as the number of
      gain settings available.

      This means when the info callback subtracts the minimum value from the
      maximum value to calculate the number of gain levels available it is
      actually under reporting the available levels. This patch fixes this
      issue by adding a new snd_soc_info_volsw_sx callback that does not
      subtract the minimum value.

      rbd: use writefull op for object size writes

      This covers only the simplest case - an object size sized write, but
      it's still useful in tiering setups when EC is used for the base tier
      as writefull op can be proxied, saving an object promotion.

      Even though updating ceph_osdc_new_request() to allow writefull should
      just be a matter of fixing an assert, I didn't do it because its only
      user is cephfs.  All other sites were updated.

      Reflects ceph.git commit 7bfb7f9025a8ee0d2305f49bf0336d2424da5b5b.

      of 1024, but it's not good enough: we set max_hw_sectors to rbd object
      size because we don't want object sized I/Os to be split, and the
      default object size is 4M.

      So, set max_sectors to max_hw_sectors in rbd at queue init time.

      The issue is easily reproducible with a simple instrumentation: if
      mdelay(10) is put between mp_setup_entry() and mp_register_handler() calls
      in mp_irqdomain_alloc() Hyper-V guest always fails to boot when re-routing
      IRQ0. The issue seems to be caused by the fact that we don't disable
      interrupts while doing IOPIC programming for legacy IRQs and IRQ0 actually
      happens.

      Protect the setup sequence against concurrent interrupts.

      mlxsw: Driver update, add initial support for Spectrum ASIC

      Purpose of this patchset is to introduce initial support for Mellanox
      Spectrum ASIC, including L2 bridge forwarding offload.

      The only non-mlxsw patch in this patchset is the first one, introducing
      pre-change upper notifier. That is used in last patch to ensure ports of
      single ASIC are not bridged into multiple bridges, as that scenario is
      currently not supported by driver.

      In the newly introduced Spectrum switch ASIC, packets destined to not

      The flooding table used is of type per-FID, which allows one to create

      While using a simple single-entry flood table is certainly sufficient at

      0 and wall time timers are going to expire with a delay of 45 years.

      Intel Wired LAN Driver Updates 2015-10-16

      This series contains updates to e1000, e1000e, igb, igbvf, ixgbe, ixgbevf,
      i40e, i40evf and fm10k.

      Alex Duyck fixes the polling routine for i40e/i40evf were the NAPI budget
      for receive cleanup was being rounded up to 1 but the netpoll call was
      expecting no Rx to be processed as the budget passed was 0.  Also cleaned
      up IN_NETPOLL flag that was not adding any value due to the receive
      cleanup was handled in NAPI.  Added support for netpoll for i40evf as
      well.

      Jesse updates all of our drivers to use napi_complete_done() instead of
      napi_complete(), which allows us to use
      /sys/class/net/ethX/gro_flush_timeout.  Added ethtool support to control
      and report the new Interrupt Limit register, since the XL710 hardware
      has a different interrupt moderation design that can support a limit of
      total interrupts per second per vector.

      Shannon cleans up startup log entries to cut down the number by putting
      a couple behind debug flags and combining others into single line.  Added
      support to enable/disable printing VEB statistics via ethtool.

      Jingjing fixes a compile issue by adding const to functions that return
      strings that are not going to be modified.

      Greg Rose cleans up defines that were not used and were causing customer
      confusion.

      Greg Bowers adds support for setting a new bit in the Set Local LLDP MIB
      admin queue command Type field.

      Mitch fixes an issue where vlan_features field was set to the same value
      as netdev features field, but before the features were actually being
      set up, leaving the vlan_features empty.  Resolve the issue by setting
      up the netdev features first, then mask out the VLAN feature bits when
      assigning vlan_features.  Fixed VF init timing, where in some instances
      the VFs would fail to initialize the first time you loaded the driver.
      To correct this, increased the delay time for the init task and wait
      longer before giving up.

      v2: fix missing space in function header comment in patch 3, based on
          feedback from Sergei Shtylyov.

      ath10k: configure copy engine 5 for HTT messages

      Currently target to host (T2H) HTT messages are received at copy engine 1.
      These messages are processed by HTC layer in both host and target.
      To avoid HTC level processing overhead in both host and target,
      the unused copy engine 5 is being used for receiving HTT T2H messages.
      This will speedup the receive data processing as well as htt tx 
completion.
      Hence host and target copy engine configuration tables are updated
      to enable CE5 pipe. The in-direction HTT mapping is now pointing to CE5
      for all HTT T2H.

      Moreover HTT send completion messages are polled from HTC handler
      as CE 4 is not interrupt-driven. For faster tx completion, CE4 polling
      needs to be done whenever CE pipe which transports HTT Rx (target->host)
      is processed. This avoids overhead of polling HTT messages from HTC
      layer. Servicing CE 4 faster is helping to solve "failed to transmit

      PCI/MSI: Allow the MSI domain to be device-specific

      So far, we've always considered that for a given PCI device, its
      MSI controller was either set by the architecture-specific
      pcibios hook, or simply inherited from the host bridge.

      This doesn't cover things like firmware-defined topologies like
      msi-map (DT) or IORT (ACPI), which can provide information about
      which MSI controller to use on a per-device basis.

      This patch adds the necessary hook into the MSI code to allow this
      feature, and provides the msi-map functionnality as a first
      implementation.

      PCI: Add per-device MSI domain hook

      So far, we have considered that the MSI domain for a device was
      either set via the architecture-dependent pcibios implementation
      or inherited from the host bridge.

      As we're about to break that assumption, add pci_dev_msi_domain
      which is the equivalent of pci_host_bridge_msi_domain, but for
      a single device.

      Other than moving things around a bit, this patch on its own
      has no effect.

      of/irq: Use the msi-map property to provide device-specific MSI domain

      While msi-parent is used to point to the MSI controller that
      works for all the devices behind a root complex, it doesn't
      allow configurations where each individual device can be routed
      to a separate MSI controller.

      The msi-map property provides this flexibility (and much more),
      so let's add a utility function that parses it, and return the
      corresponding MSI domain.

      of/irq: Add support code for multi-parent version of "msi-parent"

      Since 126b16e2ad98 ("Docs: dt: add generic MSI bindings"),
      the definition of "msi-parent" has evolved, while maintaining
      some degree of compatibility. It can now express multiple MSI
      controllers as parents, as well as some sideband data being
      communicated to the controller.

      This patch adds the parsing of the property, iterating over
      the multiple parents until a suitable irqdomain is found.
      It can also fallback to the original parsing if the old
      binding is detected.

      This support code gets used in the subsequent patches.

      i40e: increase AQ work limit

      With 64 VFs, we can easily overwhelm the AQ on the PF if we have too low
      a limit on the number of AQ requests. This leads to ARQ overflow errors,
      and occasionally VFs that fail to initialize.

      Since we really only hit this condition on initial VF driver load, the
      requests that we process are lightweight, so this extra work doesn't
      cause problems for the PF driver.

      i40evf: relax and stagger init timing a bit

      On some devices, in some systems, in some configurations, the VFs would
      fail to initialize the first time you loaded the driver.

      To correct this, increase the delay time for the init task slightly, and
      wait longer before giving up.

      If we enable VFs and load the VF driver in the same kernel as the PF
      driver, we can totally overwhelm the PF driver with AQ requests because
      all of the instances try to initialize at the same time.

      To help alleviate this, stagger the initial scheduling of the init task
      using the PCIe function as a multiplier. We mask off the function to
      only three bits so no instance has to wait too long.

      With these two changes, initializing 128 VFs on a single device goes
      from four minutes to just a few seconds.

      i40evf: correctly populate vlan_features

      The vlan_features field was correctly being set to the same value as the
      netdev features field. However, this was being done before the features
      were actually being set up, leaving the vlan_features empty.

      Also, after a reset, vlan_features will be incorrectly assigned the
      previous netdev feature flags, which can contain VLAN feature bits. This
      makes the VLAN code angry and will cause a stack dump.

      To fix these issues, set up the netdev features first, then mask out the
      VLAN feature bits when assigning vlan_features.

      i40e/i40evf: moderate interrupts differently

      The XL710 hardware has a different interrupt moderation design
      that can support a limit of total interrupts per second per
      vector, in addition to the "number of interrupts per second"
      controls already established in the driver.  This combination
      of hardware features allows us to set very low default latency
      settings but minimize the total CPU utilization by not
      making too many interrupts, should the user desire.

      The current driver implementation is still enabling the dynamic
      moderation in the driver, and only using the rx/tx-usecs
      limit in ethtool to limit the interrupt rate per second, by default.

      The new code implemented in this patch
      2) adds init/use of the new "Interrupt Limit" register
      3) adds ethtool knob to control/report the limits above

      Usage is ethtool -C ethx rx-usecs-high <value> Where <value> is number
      of microseconds to create a rate of 1/N interrupts per second,
      regardless of rx-usecs or tx-usecs values. Since there is a credit based
      scheme in the hardware, the rx-usecs and tx-usecs can be configured for
      very low latency for short bursts, but once the credit runs out the
      refill rate on the credits is limited by rx-usecs-high.

      i40e: remove read/write failed messages from nvmupdate

      Allow the nvmupdate application to decide when a read or write error
      should be exposed to the user.  Since the application needs to use
      write probes to find the ReadOnly sections on a potentially unknown NVM
      version in the HW and read probes to check the status of the last write,
      some error messages are expected, but need not be shown to the users.
      The driver doesn't know which are ignorable from real errors, so needs
      to let the application make the decision.

      drivers/net/intel: use napi_complete_done()

      As per Eric Dumazet's previous patches:
      (see commit (24d2e4a50737) - tg3: use napi_complete_done())

      Quoting verbatim:
      Using napi_complete_done() instead of napi_complete() allows
      us to use /sys/class/net/ethX/gro_flush_timeout

      GRO layer can aggregate more packets if the flush is delayed a bit,
      without having to set too big coalescing parameters that impact
      latencies.

      i40e/i40evf: Drop useless "IN_NETPOLL" flag

      The code in i40e and i40evf is using an "IN_NETPOLL" flag that has never
      added any value due to the fact that the Rx clean-up is handled in NAPI.
      As such the flag was set, the queue was scheduled via NAPI, and then 
polled
      from the netpoll controller and if any Rx packets were processed the were
      processed in the wrong context.

      In addition the flag itself just added an unneeded conditional to the
      hot-path so it can safely be dropped and save us a few instructions.

      i40e/i40evf: Fix handling of napi budget

      The polling routine for i40e was rounding up the budget for Rx cleanup to
      1.  This is incorrect as the netpoll poll call is expecting no Rx to be
      processed as the budget passed was 0.

      of/irq: Add new function of_msi_map_rid()

      The device tree property "msi-map" specifies how to create the PCI
      requester id used in some MSI controllers.  Add a new function
      of_msi_map_rid() that finds the msi-map property and applies its
      translation to a given requester id.

      Docs: dt: Add PCI MSI map bindings

      Currently msi-parent is used by a few bindings to describe the
      relationship between a PCI root complex and a single MSI controller, but
      this property does not have a generic binding document.

      Additionally, msi-parent is insufficient to describe more complex
      relationships between MSI controllers and devices under a root complex,
      where devices may be able to target multiple MSI controllers, or where
      MSI controllers use (non-probeable) sideband information to distinguish
      devices.

      This patch adds a generic binding for mapping PCI devices to MSI
      controllers. This document covers msi-parent, and a new msi-map property
      (specific to PCI*) which may be used to map devices (identified by their
      Requester ID) to sideband data for each MSI controller that they may
      target.

      genirq/msi: Do not use pci_msi_[un]mask_irq as default methods

      When we create a generic MSI domain, that MSI_FLAG_USE_DEF_CHIP_OPS
      is set, and that any of .mask or .unmask are NULL in the irq_chip
      structure, we set them to pci_msi_[un]mask_irq.

      This is a bad idea for at least two reasons:
      - PCI_MSI might not be selected, kernel fails to build (yes, this is
        legitimate, at least on arm64!)
      - This may not be a PCI/MSI domain at all (platform MSI, for example)

      Either way, this looks wrong. Move the overriding of mask/unmask to
      the PCI counterpart, and panic is any of these two methods is not
      set in the core code (they really should be present).

         unmapped GDT in efi_call_phys_prolog(). (Paolo Bonzini)

      x86/setup: Extend low identity map to cover whole kernel range

      On 32-bit systems, the initial_page_table is reused by
      efi_call_phys_prolog as an identity map to call
      SetVirtualAddressMap.  efi_call_phys_prolog takes care of
      converting the current CPU's GDT to a physical address too.

      For PAE kernels the identity mapping is achieved by aliasing the
      first PDPE for the kernel memory mapping into the first PDPE
      of initial_page_table.  This makes the EFI stub's trick "just work".

      However, for non-PAE kernels there is no guarantee that the identity
      mapping in the initial_page_table extends as far as the GDT; in this
      case, accesses to the GDT will cause a page fault (which quickly becomes
      a triple fault).  Fix this by copying the kernel mappings from
      swapper_pg_dir to initial_page_table twice, both at PAGE_OFFSET and at
      identity mapping.

      For some reason, this is only reproducible with QEMU's dynamic translation
      mode, and not for example with KVM.  However, even under KVM one can 
clearly
      see that the page table is bogus:

          $ qemu-system-i386 -pflash OVMF.fd -M q35 vmlinuz0 -s -S -daemonize
          $ gdb
          (gdb) target remote localhost:1234
          (gdb) hb *0x02858f6f
          Hardware assisted breakpoint 1 at 0x2858f6f
          (gdb) c
          Continuing.

          Breakpoint 1, 0x02858f6f in ?? ()
          (gdb) monitor info registers
          ...
          GDT=     0724e000 000000ff

          CR0=0005003b CR2=ff896000 CR3=032b7000 CR4=00000690
          ...

      The page directory is sane:

          (gdb) x/4wx 0x32b7000
          0x32b7000:    0x03398063      0x03399063      0x0339a063

0x00403003

      but our particular page directory entry is empty:

          (gdb) x/1wx 0x32b7000 + (0x724e000 >> 22) * 4
          0x32b7070:    0x00000000

      [ It appears that you can skate past this issue if you don't receive
        any interrupts while the bogus GDT pointer is loaded, or if you avoid
        reloading the segment registers in general.

        Andy Lutomirski provides some additional insight:

         "AFAICT it's entirely permissible for the GDTR and/or LDT
          descriptor to point to unmapped memory.  Any attempt to use them
          (segment loads, interrupts, IRET, etc) will try to access that memory
          as if the access came from CPL 0 and, if the access fails, will
          generate a valid page fault with CR2 pointing into the GDT or
          LDT."

        Up until commit 23a0d4e8fa6d ("efi: Disable interrupts around EFI
        calls, not in the epilog/prolog calls") interrupts were disabled
        around the prolog and epilog calls, and the functional GDT was
        re-installed before interrupts were re-enabled.

        Which explains why no one has hit this issue until now. ]

      At the time of above commit, tcp_req_err() and dccp_req_err()

      ipv6: Initialize rt6_info properly in ip6_blackhole_route()

      ip6_blackhole_route() does not initialize the newly allocated
      rt6_info properly.  This patch:
      1. Call rt6_info_init() to initialize rt6i_siblings and rt6i_uncached

      2. The current rt->dst._metrics init code is incorrect:
         - 'rt->dst._metrics = ort->dst._metris' is not always safe
         - Not sure what dst_copy_metrics() is trying to do here
           considering ip6_rt_blackhole_cow_metrics() always returns
           NULL

         Fix:
         - Always do dst_copy_metrics()
         - Replace ip6_rt_blackhole_cow_metrics() with
           dst_cow_metrics_generic()

      3. Mask out the RTF_PCPU bit from the newly allocated blackhole route.
         This bug triggers an oops (reported by Phil Sutter) in 
rt6_get_cookie().
         It is because RTF_PCPU is set while rt->dst.from is NULL.

      Bluetooth: Fix LE reconnection logic

      We can't use hci_explicit_connect_lookup() since that would only cover
      explicit connections, leaving normal reconnections completely
      untouched. Not using it in turn means leaving out entries in
      pend_le_reports.

      To fix this and simplify the logic move conn params from the reports
      list to the pend_le_conns list for the duration of an explicit
      connect. Once the connect is complete move the params back to the
      pend_le_reports list. This also means that the explicit connect lookup
      function only needs to look into the pend_le_conns list.

      Bluetooth: Fix reference counting for LE-scan based connections

      The code should never directly call hci_conn_hash_del since many
      cleanup & reference counting updates would be lost. Normally
      hci_conn_del is the right thing to do, but in the case of a connection
      doing LE scanning this could cause a deadlock due to doing a
      cancel_delayed_work_sync() on the same work callback that we were
      called from.

      Connections in the LE scanning state actually need very little cleanup
      - just a small subset of hci_conn_del. To solve the issue, refactor
      out these essential pieces into a new hci_conn_cleanup() function and
      call that from the two necessary places.

      Bluetooth: Fix double scan updates

      When disable/enable scan command is issued twice, some controllers
      will return an error for the second request, i.e. requests with this
      command will fail on some controllers, and succeed on others.

      This patch makes sure that unnecessary scan disable/enable commands
      are not issued.

      When adding device to the auto connect whitelist when there is pending
      connect attempt, there is no need to update scan.

      hci_connect_le_scan_cleanup is conditionally executing
      hci_conn_params_del, that is calling hci_update_background_scan. Make
      the other case also update scan, and remove reduntand call from
      hci_connect_le_scan_remove.

      When stopping interleaved discovery the state should be set to stopped
      only when both LE scanning and discovery has stopped.

      tipc: update node FSM when peer RESET message is received

      The change made in the previous commit revealed a small flaw in the way
      the node FSM is updated. When the function tipc_node_link_down() is
      called for the last link to a node, we should check whether this was
      caused by a local reset or by a received RESET message from the peer.
      In the latter case, we can directly issue a PEER_LOST_CONTACT_EVT to
      the node FSM, so that it is ready to re-establish contact. If this is
      not done, the peer node will sometimes have to go through a second
      establish cycle before the link becomes stable.

      We fix this in this commit by conditionally issuing the mentioned
      event in the function tipc_node_link_down(). We also move LINK_RESET
      FSM even away from the link_reset() function and into the caller
      function, partially because it is easier to follow the code when state
      changes are gathered at a limited number of locations, partially
      because there will be cases in future commits where we don't want the
      link to go RESET mode when link_reset() is called.

      tipc: send out RESET immediately when link goes down

      When a link is taken down because of a node local event, such as
      disabling of a bearer or an interface, we currently leave it to the
      peer node to discover the broken communication. The default time for
      such failure discovery is 1.5-2 seconds.

      If we instead allow the terminating link endpoint to send out a RESET
      message at the moment it is reset, we can achieve the impression that
      both endpoints are going down instantly. Since this is a very common
      scenario, we find it worthwhile to make this small modification.

      Apart from letting the link produce the said message, we also have to
      ensure that the interface is able to transmit it before TIPC is
      detached. We do this by performing the disabling of a bearer in three
      steps:

      1) Disable reception of TIPC packets from the interface in question.
      2) Take down the links, while allowing them so send out a RESET message.
      3) Disable transmission of TIPC packets on the interface.

      Apart from this, we now have to react on the NETDEV_GOING_DOWN event,
      instead of as currently the NEDEV_DOWN event, to ensure that such
      transmission is possible during the teardown phase.

      tipc: delay ESTABLISH state event when link is established

      Link establishing, just like link teardown, is a non-atomic action, in
      the sense that discovering that conditions are right to establish a link,
      and the actual adding of the link to one of the node's send slots is done
      in two different lock contexts. The link FSM is designed to help bridging
      the gap between the two contexts in a safe manner.

      We have now discovered a weakness in the implementaton of this FSM.
      Because we directly let the link go from state LINK_ESTABLISHING to
      state LINK_ESTABLISHED already in the first lock context, we are unable
      to distinguish between a fully established link, i.e., a link that has
      been added to its slot, and a link that has not yet reached the second
      lock context. It may hence happen that a manual intervention, e.g., when
      disabling an interface, causes the function tipc_node_link_down() to try
      removing the link from the node slots, decrementing its active link
      counter etc, although the link was never added there in the first place.

      We solve this by delaying the actual state change until we reach the
      second lock context, inside the function tipc_node_link_up(). This
      makes it possible for potentail callers of __tipc_node_link_down() to
      know if they should proceed or not, and the problem is solved.

      Unforunately, the situation described above also has a second problem.
      Since there by necessity is a tipc_node_link_up() call pending once
      the node lock has been released, we must defuse that call by setting
      the link back from LINK_ESTABLISHING to LINK_RESET state. This forces
      us to make a slight modification to the link FSM, which will now look
      as follows.

      tipc: disallow packet duplicates in link deferred queue

      After the previous commits, we are guaranteed that no packets
      of type LINK_PROTOCOL or with illegal sequence numbers will be
      attempted added to the link deferred queue. This makes it possible to
      make some simplifications to the sorting algorithm in the function
      tipc_skb_queue_sorted().

      We also alter the function so that it will drop packets if one with
      the same seqeunce number is already present in the queue. This is
      necessary because we have identified weird packet sequences, involving
      duplicate packets, where a legitimate in-sequence packet may advance to
      the head of the queue without being detected and de-queued.

      Finally, we make this function outline, since it will now be called only
      in exceptional cases.

      tipc: improve sequence number checking

      The sequence number of an incoming packet is currently only checked
      for less than, equality to, or bigger than the next expected number,
      meaning that the receive window in practice becomes one half sequence
      number cycle, or U16_MAX/2. This does not make sense, and may not even
      be safe if there are extreme delays in the network. Any packet sent by
      the peer during the ongoing cycle must belong inside his current send
      window, or should otherwise be dropped if possible.

      Since a link endpoint cannot know its peer's current send window, it
      has to base this sanity check on a worst-case assumption, i.e., that
      the peer is using a maximum sized window of 8191 packets. Using this
      assumption, we now add a check that the sequence number is not bigger
      than next_expected + TIPC_MAX_LINK_WIN. We also re-order the checks
      done, so that the receive window test is performed before the gap test.
      This way, we are guaranteed that no packet with illegal sequence numbers
      are ever added to the deferred queue.

      tipc: simplify tipc_link_rcv() reception loop

      Currently, all packets received in tipc_link_rcv() are unconditionally
      added to the packet deferred queue, whereafter that queue is walked and
      all its buffers evaluated for delivery. This is both non-optimal and
      and makes the queue sorting function unnecessary complex.

      This commit changes the loop so that an arrived packet is evaluated
      first, and added to the deferred queue only when a sequence number gap
      is discovered. A non-empty deferred queue is walked until it is empty
      or until its head's sequence number doesn't fit.

      tipc: limit usage of temporary skb list during packet reception

      During packet reception, the function tipc_link_rcv() adds its accepted
      packets to a temporary buffer queue, before finally splicing this queue
      into the lock protected input queue that will be delivered up to the
      socket layer. The purpose is to reduce potential contention on the input
      queue lock. However, since the vast majority of packets arrive in
      sequence, they will anyway be added one by one to the input queue, and
      the use of the temporary queue becomes a sub-optimization.

      The only case where this queue makes sense is when unpacking buffers
      from a bundle packet; here we want to avoid dozens of small buffers
      to be added individually to the lock-protected input queue in a tight
      loop.

      In this commit, we remove the general usage of the temporary queue,
      and keep it only for the packet unbundling case.

      mlxsw: Add trap group for control packets

      Previously, we trapped flooded and control packets using the same trap
      group. This can cause flooded packets to overflow the PCI bus and
      prevent control packets (e.g. STP, LACP) from getting to the CPU.

      Solve this by splitting the RX trap group to RX and control, which allows
      us to configure a policer on the first, thereby preventing it from
      overflowing the PCI bus.

      drm/virtio: use %llu format string form atomic64_t

      The virtgpu driver prints the last_seq variable using the %ld or
      %lu format string, which does not work correctly on all architectures
      and causes this compiler warning on ARM:

      drivers/gpu/drm/virtio/virtgpu_fence.c: In function 
'virtio_timeline_value_str':
      drivers/gpu/drm/virtio/virtgpu_fence.c:64:22: warning: format '%lu' 
expects argument of type 'long unsigned int', but argument 4 has type 'long 
long int' [-Wformat=]
        snprintf(str, size, "%lu", atomic64_read(&fence->drv->last_seq));
                            ^

[-Wformat=]
        seq_printf(m, "fence %ld %lld\n",
                      ^

      In order to avoid the warnings, this changes the format strings to %llu
      and adds a cast to u64, which makes it work the same way everywhere.

        we found an issue in the namespace lookup code related to RoCE and
        this works around the issue for now (we allow a lookup with a
        namespace to succeed on RoCE since RoCE namespaces aren't implemented
        yet).  This will go away in 4.4 when we put in support for namespaces
        in RoCE devices.

        The last one is large in terms of lines, but is all legal and no
        functional changes.  Cisco needed to update their files to be more
        specific about their license.  They had intended the files to be dual

        license tag, but their file headers were not up to par.  They
        contacted all of the contributors to get agreement and then submitted

      vmstat: explicitly schedule per-cpu work on the CPU we need it to run on

      The vmstat code uses "schedule_delayed_work_on()" to do the initial
      startup of the delayed work on the right CPU, but then once it was
      started it would use the non-cpu-specific "schedule_delayed_work()" to
      re-schedule it on that CPU.

      That just happened to schedule it on the same CPU historically (well, in
      almost all situations), but the code _requires_ this work to be per-cpu,
      and should say so explicitly rather than depend on the non-cpu-specific
      scheduling to schedule on the current CPU.

      The timer code is being changed to not be as single-minded in always
      running things on the calling CPU.

      See also commit 874bbfe600a6 ("workqueue: make sure delayed work run in
      local cpu") that for now maintains the local CPU guarantees just in case
      there are other broken users that depended on the accidental behavior.

      Resources are reallocated for requeued commands, so unmap and release

      It's a pretty bad memory leak and causes a kernel hang if you remove a

        nvme 0000:xx:xx.x: dma_pool_destroy prp list 256, ffff880420dec000 busy

      and lock up pci and the driver since removal never completes while

      KEYS: Fix crash when attempt to garbage collect an uninstantiated keyring

      The following sequence of commands:

          i=`keyctl add user a a @s`
          keyctl request2 keyring foo bar @t
          keyctl unlink $i @s

      tries to invoke an upcall to instantiate a keyring if one doesn't already
      exist by that name within the user's keyring set.  However, if the upcall
      fails, the code sets keyring->type_data.reject_error to -ENOKEY or some
      other error code.  When the key is garbage collected, the key destroy
      function is called unconditionally and keyring_destroy() uses list_empty()

      gpio: pl061: assign the apropriate handler for irqs

      The PL061 can handle level IRQs and edge IRQs, however it is
      just utilizing handle_simple_irq() for all IRQs. Inspired by
      Stefan Agners patch to vf610, this assigns the right handler
      depending on what type is set up, and after this
      handle_bad_irq() is only used as default and if the type is
      not specified, as is done in the OMAP driver: defining the
      IRQ type is really not optional for this driver.

      The interrupt handler was just writing the interrupt clearing
      register for all lines that were high when entering the handling
      loop, this is wrong: that register is only supposed to be
      written (on a per-line basis) for edge IRQs, so this ACK
      was moved to the .irq_ack() callback as is proper.

      Tested with PL061 on the ARM RealView PB11MPCore and the
      MMC/SC card detect GPIO.

      ARM: tegra: Comment out gpio-ranges properties

      While the addition of these properties is technically correct it unveils
      a bug with deferred probe. The problem is that the presence of the gpio-
      range property causes the gpio-tegra driver to defer probe (it needs the
      pinctrl driver to be ready). That's technically correct, but it causes a
      couple of issues:

        - The keyboard on Chromebooks stops working. The reason for that is
          that the gpio-tegra device has not registered an IRQ domain by the
          time the EC SPI device is registered, hence the interrupt number
          resolves to 0. This is technically a bug in the SPI core, since it
          should really resolve the interrupt at probe time and defer if the
          IRQ domain isn't available yet. This is similar to what's done for
          I2C and platform device already.

        - The gpio-tegra device deferring probe means that it is moved to the
          end of the dpm_list. This list defines the suspend/resume order for
          devices. However the core lacks a way to move all users of the
          gpio-tegra device to the end of the dpm_list at the same time. This
          in turn results in a subtle bug on Jetson TK1, where the gpio-keys
          device is used to expose the power key as input. The power key is a
          convenient way to wake the system from suspend. Interestingly, the
          gpio-keys device ends up getting probed at a point after gpio-tegra
          has been probed successfully from having been deferred earlier. As
          such the driver doesn't need to defer the probe itself, and hence
          the device isn't moved to the end of the dpm_list. This causes the
          gpio-tegra device to be suspended before gpio-keys, which in turn
          leaves gpio-keys unable to wake the system from suspend.

      There are patches in the works to fix both of the above issues, but they
      are too involved to make it into v4.3, so in the meantime let's fix the
      regressions by commenting out the gpio-ranges properties until the fixes
      have landed.

      block: don't release bdi while request_queue has live references

      bdi's are initialized in two steps, bdi_init() and bdi_register(), but
      destroyed in a single step by bdi_destroy() which, for a bdi embedded
      in a request_queue, is called during blk_cleanup_queue() which makes
      the queue invisible and starts the draining of remaining usages.

      A request_queue's user can access the congestion state of the embedded
      bdi as long as it holds a reference to the queue.  As such, it may
      access the congested state of a queue which finished
      blk_cleanup_queue() but hasn't reached blk_release_queue() yet.
      Because the congested state was embedded in backing_dev_info which in
      turn is embedded in request_queue, accessing the congested state after
      bdi_destroy() was called was fine.  The bdi was destroyed but the
      memory region for the congested state remained accessible till the
      queue got released.

      a13f35e87140 ("writeback: don't embed root bdi_writeback_congested in
      bdi_writeback") changed the situation.  Now, the root congested state
      which is expected to be pinned while request_queue remains accessible
      is separately reference counted and the base ref is put during
      bdi_destroy().  This means that the root congested state may go away
      prematurely while the queue is between bdi_dstroy() and
      blk_cleanup_queue(), which was detected by Andrey's KASAN tests.

      The root cause of this problem is that bdi doesn't distinguish the two
      steps of destruction, unregistration and release, and now the root
      congested state actually requires a separate release step.  To fix the
      issue, this patch separates out bdi_unregister() and bdi_exit() from
      bdi_destroy().  bdi_unregister() is called from blk_cleanup_queue()
      and bdi_exit() from blk_release_queue().  bdi_destroy() is now just a
      simple wrapper calling the two steps back-to-back.

      While at it, the prototype of bdi_destroy() is moved right below
      bdi_setup_and_register() so that the counterpart operations are
      located together.

      clocksource/drivers/exynos_mct: Use container_of() instead of 
this_cpu_ptr()

      Since evt structure is embedded in per-CPU mevt structure it's
      definitely faster to use container_of() to get access to mevt
      if we have evt (for example as incoming function argument) instead
      of more expensive approach with this_cpu_ptr(&percpu_mct_tick).
      this_cpu_ptr() on per-CPU mevt structure leads to access to cp15
      to get cpu id and arithmetic operations.
      Container_of() is cheaper since it's just one asm instruction.
      This should work if used evt pointer is correct and owned by
      local mevt structure.

      For example, before this patch set_state_shutdown() looks like:

       4a4:     e92d4010        push    {r4, lr}
       4a8:     e3004000        movw    r4, #0

       4d0:     e8bd8010        pop     {r4, pc}

      With this patch:

       4a4:     e92d4010        push    {r4, lr}
       4a8:     e59000c0        ldr     r0, [r0, #192]  ; 0xc0

      cfg80211: reg: remove useless reg_timeout scheduling

      When the functions reg_set_rd_driver() and reg_set_rd_country_ie()
      return with an error, the calling function already restores data
      by calling restore_regulatory_settings(), so there's no need to
      also schedule a timeout (which would lead to other side effects
      such as indicating CRDA failed, which clearly isn't true.) Remove
      the scheduling.

      Merge branch 'switchdev-locking'

      Jiri Pirko says:

      ====================
      switchdev: change locking

      This is something which I'm currently struggling with.
      Callers of attr_set and obj_add/del often hold not only RTNL, but also
      spinlock (bridge). So in that case, the driver implementing the op cannot 
sleep.

      The way rocker is dealing with this now is just to invoke driver operation
      and go out, without any checking or reporting of the operation status.

      Since it would be nice to at least put a warning in case the operation 
fails,
      it makes sense to do this in delayed work directly in switchdev core
      instead of implementing this in separate drivers. And that is what this 
patchset
      is introducing.

      So from now on, the locking of switchdev mod ops is consistent. Caller 
either
      holds rtnl mutex or in case it does not, caller sets defer flag, telling
      switchdev core to process the op later, in deferred queue.

      Function to force to process switchdev deferred ops can be called by op
      caller in appropriate location, for example after it releases
      spin lock, to force switchdev core to process pending ops.

      v1->v2:
      - rebased on current net-next head (including Scott's ageing patchset)
      v2->v3:
      - fixed comment s/of/or/ typo suggested by Nik
      v3->v4:
      - the actual patchset is sent instead of different branch I send in v3 :/
      v4->v5:
      - added patch to "const" attr param
      - reworked deferred ops infrastructure (mainly patch number 1 and
        internal users (patch 3 and 5)) - resolves the issue pointed out
        by John

      switchdev: introduce possibility to defer obj_add/del

      Similar to the attr usecase, the caller knows if he is holding RTNL and is
      in atomic section. So let the called to decide the correct call variant.

      This allows drivers to sleep inside their ops and wait for hw to get the
      operation status. Then the status is propagated into switchdev core.
      This avoids silent errors in drivers.

      switchdev: allow caller to explicitly request attr_set as deferred

      Caller should know if he can call attr_set directly (when holding RTNL)
      or if he has to defer the att_set processing for later.

      This also allows drivers to sleep inside attr_set and report operation
      status back to switchdev core. Switchdev core then warns if status is
      not ok, instead of silent errors happening in drivers.

      Benefit from newly introduced switchdev deferred ops infrastructure.

      crypto: keywrap - add key wrapping block chaining mode

      This patch implements the AES key wrapping as specified in
      NIST SP800-38F and RFC3394.

      The implementation covers key wrapping without padding.

      IV handling: The caller does not provide an IV for encryption,
      but must obtain the IV after encryption which would serve as the first
      semblock in the ciphertext structure defined by SP800-38F. Conversely,
      for decryption, the caller must provide the first semiblock of the data
      as the IV and the following blocks as ciphertext.

      The key wrapping is an authenticated decryption operation. The caller
      will receive EBADMSG during decryption if the authentication failed.

      Albeit the standards define the key wrapping for AES only, the template
      can be used with any other block cipher that has a block size of 16
      bytes. During initialization of the template, that condition is checked.
      Any cipher not having a block size of 16 bytes will cause the
      initialization to fail.

      Intel Wired LAN Driver Updates 2015-10-15

      This series contains updates to i40e, i40evf and ixgbe.

      Emil changes the ixgbe driver to disable LRO by default in favor or GRO.

      Mark provides two changes for ixgbe, first fixes a semaphore issue when
      a reset never completes, it is necessary to retake the semaphore before
      returning.

      Jesse fixes up a missing function header comment variable reference.  Then
      enables ethtool priv flags to control flow director at runtime.

      Neerav changes several i40e error messages to debug only since the
      messages were printing when there was no functional issue and were meant
      for debug only.

      Catherine changes the i40e driver to make only X722 support 100M SGMII,
      since it is the only device to actually support it.

      Anjali modifies the i40e/i40evf driver to add writeback on ITR offload
      support for X722 since the device has a way to work around the
      descriptor writeback issue.

      Mitch cleans up obsolete code.  Also reduces the i40evf init time by
      shortening up the delays in the init task to aid in performance in
      load/unload tests and mitigates DMAR errors in VF enable/disable tests.

      Shannon modifies i40e to allow flow director sideband when the device
      is in MFP mode and only has one partition enabled, since we still have
      plenty of interrupts for managing the flow director activity.  Also
      cleaned up flow director ATR control in debugfs since the priv flag
      has been added to our ethtool interface.  Makes several general code
      cleanups of redundant or unnecessary code for i40e.

      posix_cpu_timer: Reduce unnecessary sighand lock contention

      It was found while running a database workload on large systems that
      significant time was spent trying to acquire the sighand lock.

      The issue was that whenever an itimer expired, many threads ended up
      simultaneously trying to send the signal. Most of the time, nothing
      happened after acquiring the sighand lock because another thread
      had just already sent the signal and updated the "next expire" time.
      The fastpath_timer_check() didn't help much since the "next expire"
      time was updated after the threads exit fastpath_timer_check().

      This patch addresses this by having the thread_group_cputimer structure
      maintain a boolean to signify when a thread in the group is already
      checking for process wide timers, and adds extra logic in the fastpath
      to check the boolean.

      posix_cpu_timer: Convert cputimer->running to bool

      In the next patch in this series, a new field 'checking_timer' will
      be added to 'struct thread_group_cputimer'. Both this and the
      existing 'running' integer field are just used as boolean values. To
      save space in the structure, we can make both of these fields booleans.

      This is a preparatory patch to convert the existing running integer
      field to a boolean.

      posix_cpu_timer: Check thread timers only when there are active thread 
timers

      The fastpath_timer_check() contains logic to check for if any timers
      are set by checking if !task_cputime_zero(). Similarly, we can do this
      before calling check_thread_timers(). In the case where there
      are only process-wide timers, this will skip all of the computations for
      per-thread timers when there are no per-thread timers.

      As suggested by George, we can put the task_cputime_zero() check in
      check_thread_timers(), since that is more of an optization to the
      function. Similarly, we move the existing check of cputimer->running
      to check_process_timers().

      In fastpath_timer_check(), the task_cputime() function is always

      necessary if there are no per-thread timers to check for. This patch
      modifies the code such that we compute the task_cputime values only
      when there are per-thread timers set.

      i40evf: speed up init

      Shorten up the delays in the init task, allowing the VF driver to
      initialize faster. This aids performance in load/unload tests and
      mitigates DMAR errors in VF enable/disable tests with absurdly short
      delays. In the real world, the VF driver will come up more quickly.

      The original values were set conservatively based on what we expected
      from the firmware in terms of performance. Now that the driver is in use
      and we know how well firmware responds to our requests, we can shorten
      these delays.

      This patch disables LRO by default in favor of GRO.

      LRO is incompatible with forwarding and is disabled when forwarding
      is turned on which makes the default offloads of the driver

      irqchip/gic-v2m: Add support for multiple MSI frames

      The GICv2m driver is so far limited to a single MSI frame, but
      nothing prevents an implementation from having several of them.

      This patch expands the driver to enumerate all frames, keeping
      the first one as the canonical identifier for the MSI domains.

      s390/dasd: fix list_del corruption after lcu changes

      A summary unit check occurs when the lcu updates the PAV configuration
      e.g. base PAV assignment or PAV mode at all. This requires the reset
      of the drivers internal pavgroups. Therefore the alias devices are
      flushed and moved via a temporary list to the active_devices list
      where they are not associated with a pavgroup. In conjunction with
      updates to the base device the pavgroup may be removed since both
      base_list and alias_list are empty. Unfortunately during alias flush
      and move to the active_device list from alias_list the pavgroup
      pointer is not deleted in the device private structure. This leads to
      a list del_corruption if another lcu_update tries to move the device
      in the non existent pavgroup.

      Fix by removing the pavgroup pointer after the alias device was moved
      to the active_devices list.

      netfilter: nfnetlink_log: consolidate check for instance in 
nfulnl_recv_config()

      This patch consolidates the check for valid logger instance once we have
      passed the command handling:

      The config message that we receive may contain the following info:

      1) Command only: We always get a valid instance pointer if we just
         created it. In case that the instance is being destroyed or the
         command is unknown, we jump to exit path of nfulnl_recv_config().
         This patch doesn't modify this handling.

      2) Config only: In this case, the instance must always exist since the
         user is asking for configuration updates. If the instance doesn't exist
         this returns -ENODEV.

      3) No command and no configs are specified: This case is rare. The
         user is sending us a config message with neither commands nor
         config options. In this case, we have to check if the instance exists
         and bail out otherwise. Before this patch, it was possible to send a
         config message with no command and no config updates for an
         unexisting instance without triggering an error. So this is the only
         case that changes.

      net/mlx4_core: Replace VF zero mac with random mac in mlx4_core

      By design, when no default MAC addresses are set in the Hypervisor for 
VFs,
      the VFs are passed zero-macs. When such a MAC is received by the VF, it
      generates a random MAC address and registers that MAC address
      with the Hypervisor.

      This random mac generation is currently done in the mlx4_en module.
      There is a problem, though, if the mlx4_ib module is loaded by a VF before
      the mlx4_en module. In this case, for RoCE, mlx4_ib will see the 
un-replaced
      zero-mac and register that zero-mac as part of QP1 initialization.

      Having a zero-mac in the port's MAC table creates problems for a
      Baseboard Management Console. The BMC occasionally sends packets with a
      zero-mac destination MAC. If there is a zero-mac present in the port's
      MAC table, the FW will send such BMC packets to the host driver rather 
than
      to the wire, and BMC will stop working.

      To address this problem, we move the replacement of zero-mac addresses
      with random-mac addresses to procedure mlx4_slave_cap(), which is part of 
the
      driver startup for VFs, and is before activation of mlx4_ib and mlx4_en.
      As a result, zero-mac addresses will never be registered in the port MAC 
table
      by the driver.

      In addition, when mlx4_en does initialize the net device, it needs to set
      the NET_ADDR_RANDOM flag in the netdev structure if the address was
      randomly generated. This is done so that udev on the VM does not create
      a new device name after each VF probe (VM boot and such). To accomplish 
this,
      we add a per-port flag in mlx4_dev which gets set whenever mlx4_core 
replaces
      a zero-mac with a randomly-generated mac. This flag is examined when 
mlx4_en
      initializes the net-device.

      net/mlx5_core: Add pci error handlers to mlx5_core driver

      This patch implement the pci_error_handlers for mlx5_core which allow the
      driver to recover from PCI error.

      Once an error is detected in the PCI, the mlx5_pci_err_detected is called
      and it:
      1) Marks the device to be in 'Internal Error' state.
      2) Dispatches an event to the mlx5_ib to flush all the outstanding cqes
      with error.
      3) Returns all the on going commands with error.
      4) Unloads the driver.

      Afterwards, the FW is reset and mlx5_pci_slot_reset is called and it
      enables the device and restore it's pci state.

      If the later succeeds, mlx5_pci_resume is called, and it loads the SW
      stack.

      tipc: move fragment importance field to new header position

      In commit e3eea1eb47a ("tipc: clean up handling of message priorities")
      we introduced a field in the packet header for keeping track of the
      priority of fragments, since this value is not present in the specified
      protocol header. Since the value so far only is used at the transmitting
      end of the link, we have not yet officially defined it as part of the
      protocol.

      Unfortunately, the field we use for keeping this value, bits 13-15 in
      in word 5, has turned out to be a poor choice; it is already used by the
      broadcast protocol for carrying the 'network id' field of the sending
      node. Since packet fragments also need to be transported across the
      broadcast protocol, the risk of conflict is obvious, and we see this
      happen when we use network identities larger than 2^13-1. This has
      escaped our testing because we have so far only been using small network
      id values.

      We now move this field to bits 0-2 in word 9, a field that is guaranteed
      to be unused by all involved protocols.

      ACPICA: Tables: Fix FADT dependency regression

      Some logics actually relying on the existence of FADT, currently relies on
      the number of loaded tables. This false dependency can easily trigger
      regressions. One of them has been introduced by commit 8ec3f459073e
      (ACPICA: Tables: Fix global table list issues by removing fixed table).

      The commit changing the fixed table indexes results in the change of FADT
      table index, originally, it was 3 (thus the installed table count should 
be
      greater than 4), while currently it is 0 (and the installed table count 
may
      be 3).

      This patch fixes this regression by cleaning up the code. Lv Zheng.

      Partially revert "clk: mvebu: Convert to clk_hw based provider APIs"

      This partially reverts commit eca61c9ff2588e1df373e61078e1874976315839.

      Thomas reports that it causes regressions on Armada XP devices.
      This is because of_clk_get_parent_name() relies on the property
      'clock-output-names' to resolve the name of a clock's parent,
      without trying to get the clock from the framework and call
      __clk_get_name(). Given that Armada XP devices don't have the
      'clock-output-names' property, of_clk_get_parent_name() returns
      the name of the node which doesn't match the actual parent
      clock's name at all, causing CPU clocks to never link up with
      their parents.

      EDAC: Use edac_debugfs_remove_recursive()

      debugfs_remove() is used to remove a file or a directory from the
      debugfs filesystem, but mci->debugfs might not empty.

      This can be triggered by the following sequence:

      1) Enable CONFIG_EDAC_DEBUG
      2) insmod an EDAC module (like i3000_edac or similar)
      3) rmmod this module
      4) we can see files remaining under <debugfs_mountpoint>/edac/ like
         "fake_inject", for example.

      Removing edac_core then, causes a NULL pointer dereference.

      The description in the driver states: "ABX500 does not provide auto ADC,
      so to monitor the required temperatures, a periodic work is used. It is
      more important to not wake up the CPU... If the chip gets too hot during
      a sleep state it's most likely due to external factors, such as the
      surrounding temperature and nothing can be done in S/W."

      So it makes no sense to keep IRQs enabled as it need not be wakeup
      source. This patch removes the use of IRQF_NO_SUSPEND flag

      Merge tag 'efi-next' of 
git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into core/efi

      Pull v4.4 EFI updates from Matt Fleming:

        - Make the EFI System Resource Table (ESRT) driver explicitly
          non-modular by ripping out the module_* code since Kconfig doesn't
          allow it to be built as a module anyway. (Paul Gortmaker)

        - Make the x86 efi=debug kernel parameter, which enables EFI debug
          code and output, generic and usable by arm64. (Leif Lindholm)

        - Add support to the x86 EFI boot stub for 64-bit Graphics Output
          Protocol frame buffer addresses. (Matt Fleming)

        - Detect when the UEFI v2.5 EFI_PROPERTIES_TABLE feature is enabled
          in the firmware and set an efi.flags bit so the kernel knows when
          it can apply more strict runtime mapping attributes - Ard Biesheuvel

        - Auto-load the efi-pstore module on EFI systems, just like we
          currently do for the efivars module. (Ben Hutchings)

        - Add "efi_fake_mem" kernel parameter which allows the system's EFI
          memory map to be updated with additional attributes for specific
          memory ranges. This is useful for testing the kernel code that handles
          the EFI_MEMORY_MORE_RELIABLE memmap bit even if your firmware
          doesn't include support. (Taku Izumi)

      Note: there is a semantic conflict between the following two commits:

        8a53554e12e9 ("x86/efi: Fix multiple GOP device support")
        ae2ee627dc87 ("efifb: Add support for 64-bit frame buffer addresses")

      I fixed up the interaction in the merge commit, changing the type of
      current_fb_base from u32 to u64.

      KVM: x86: fix RSM into 64-bit protected mode

      In order to get into 64-bit protected mode, you need to enable
      paging while EFER.LMA=1.  For this to work, CS.L must be 0.
      Currently, we load the segments before CR0 and CR4, which means
      that if RSM returns into 64-bit protected mode CS.L is already 1
      and everything breaks.

      Luckily, CS.L=0 is always the case when executing RSM, because it
      is forbidden to execute RSM from 64-bit protected mode.  Hence it
      is enough to load CR0 and CR4 first, and only then the segments.

      crypto: pkcs7 - Fix unaligned access in pkcs7_verify()

      On sparc, we see unaligned access messages on each modprobe[-r]:

      Kernel unaligned access at TPC[6ad9b4] pkcs7_verify [..]
      Kernel unaligned access at TPC[6a5484] crypto_shash_finup [..]

      Kernel unaligned access at TPC[101501ac] __sha1_sparc64_update [..]

      These ware triggered by mod_verify_sig() invocations of pkcs_verify(), and
      are are being caused by an unaligned desc at (sha1, digest_size is 0x14)
              desc = digest + digest_size;

      To fix this, pkcs7_verify needs to make sure that desc is pointing
      at an aligned value past the digest_size, and kzalloc appropriately,
      taking alignment values into consideration.

      crypto: marvell/cesa - factor out common import/export functions

      As all the import functions and export functions are virtually
      identical, factor out their common parts into a generic
      mv_cesa_ahash_import() and mv_cesa_ahash_export() respectively.  This
      performs the actual import or export, and we pass the data pointers and
      length into these functions.

      We have to switch a % const operation to do_div() in the common import
      function to avoid provoking gcc to use the expensive 64-bit by 64-bit
      modulus operation.

      crypto: marvell/cesa - fix wrong hash results

      Attempting to use the sha1 digest for openssh via openssl reveals that
      the result from the hash is wrong: this happens when we export the
      state from one socket and import it into another via calling accept().

      The reason for this is because the operation is reset to "initial block"
      state, whereas we may be past the first fragment of data to be hashed.

      Arrange for the operation code to avoid the initialisation of the state,
      thereby preserving the imported state.

      crypto: marvell/cesa - initialise struct mv_cesa_ahash_req

      When a AF_ALG fd is accepted a second time (hence hash_accept() is
      used), hash_accept_parent() allocates a new private context using
      sock_kmalloc().  This context is uninitialised.  After use of the new
      fd, we eventually end up with the kernel complaining:

      marvell-cesa f1090000.crypto: dma_pool_free cesa_padding, c0627770/0 (bad 
dma)

      where c0627770 is a random address.  Poisoning the memory allocated by
      the above sock_kmalloc() produces kernel oopses within the marvell hash
      code, particularly the interrupt handling.

      The following simplfied call sequence occurs:

      hash_accept()
        crypto_ahash_export()
          marvell hash export function
        af_alg_accept()
          hash_accept_parent()  <== allocates uninitialised struct hash_ctx
        crypto_ahash_import()
          marvell hash import function

      hash_ctx contains the struct mv_cesa_ahash_req in its req.__ctx member,
      and, as the marvell hash import function only partially initialises
      this structure, we end up with a lot of members which are left with
      whatever data was in memory prior to sock_kmalloc().

      Add zero-initialisation of this structure.

      Several of the algorithms in marvell/hash.c have a statesize of zero.
      When an AF_ALG accept() on an already-accepted file descriptor to
      calls into hash_accept(), this causes:

        char state[crypto_ahash_statesize(crypto_ahash_reqtfm(req))];

      to be zero-sized, but we still pass this to:

        err = crypto_ahash_export(req, state);

      which proceeds to write to 'state' as if it was a "struct md5_state",
      "struct sha1_state" etc.  Add the necessary initialisers for the
      .statesize member.

      x86/efi: Fix multiple GOP device support

      When multiple GOP devices exists, but none of them implements
      ConOut, the code should just choose the first GOP (according to
      the comments). But currently 'fb_base' will refer to the last GOP,
      while other parameters to the first GOP, which will likely
      result in a garbled display.

      I can reliably reproduce this bug using my ASRock Z87M Extreme4
      motherboard with CSM and integrated GPU disabled, and two PCIe
      video cards (NVidia GT640 and GTX980), booting from efi-stub
      (booting from grub works fine).  On the primary display the
      ASRock logo remains and on the secondary screen it is garbled
      up completely.

      tipc: eliminate risk of stalled link synchronization

      In commit 6e498158a827 ("tipc: move link synch and failover to link 
aggregation level")
      we introduced a new mechanism for performing link failover and
      synchronization. We have now detected a bug in this mechanism.

      During link synchronization we use the arrival of any packet on
      the tunnel link to trig a check for whether it has reached the
      synchronization point or not. This has turned out to be too
      permissive, since it may cause an arriving non-last SYNCH packet to
      end the synch state, just to see the next SYNCH packet initiate a
      new synch state with a new, higher synch point. This is not fatal,
      but should be avoided, because it may significantly extend the
      synchronization period, while at the same time we are not allowed
      to send NACKs if packets are lost. In the worst case, a low-traffic
      user may see its traffic stall until a LINK_PROTOCOL state message
      trigs the link to leave synchronization state.

      At the same time, LINK_PROTOCOL packets which happen to have a (non-
      valid) sequence number lower than the tunnel link's rcv_nxt value will
      be consistently dropped, and will never be able to resolve the situation
      described above.

      We fix this by exempting LINK_PROTOCOL packets from the sequence number
      check, as they should be. We also reduce (but don't completely
      eliminate) the risk of entering multiple synchronization states by only
      allowing the (logically) first SYNCH packet to initiate a synchronization
      state. This works independently of actual packet arrival order.

aggregation level")

      Revert "ipv4/icmp: redirect messages can use the ingress daddr as source"

      Revert the commit e2ca690b657f ("ipv4/icmp: redirect messages
      can use the ingress daddr as source"), which tried to introduce a more
      suitable behaviour for ICMP redirect messages generated by VRRP routers.
      However RFC 5798 section 8.1.1 states:

          The IPv4 source address of an ICMP redirect should be the address
          that the end-host used when making its next-hop routing decision.

      while said commit used the generating packet destination
      address, which do not match the above and in most cases leads to
      no redirect packets to be generated.

      Intel Wired LAN Driver Updates 2015-10-13

      This series contains updates to i40e, i40evf, ixgbe and fm10k.

      Carolyn cleans up ndo_bridge_getlink() by flagging a parameter as
      __always_unused, since it is never used.  Adds a member to the nvm_info
      struct to store OEM version info to be output either by OID or ethtool.

      Neerav cleans up a remaining bit shift to use BIT() macro.

      Mitch fixes the i40evf driver to properly handle calls to its
      ndo_set_mac_address() method.  It did not properly check to see if the
      override would be allowed by the PF driver, and it never removed the old
      address from its filter list.  Cleaned up the use of
      i40e_enable_vf_mappings() in i40e_alloc_vfs(), since it is just redundant
      since we already call it by i40e_reset_vf().  Fixed a possible panic
      in some circumstances where the firmware may fail to allocate a VSI for
      a VF by checking the return value from i40e_alloc_vf_res() and don't
      try to configure the device further if it failed.

      Greg fixes the parsing of CEE App TLVs so the caller does not have to
      consider whether the App came from a CEE or IEEE DCBx negotiation.

      Shannon moves the device ids into a standalone file due to the desire
      to write user-land drivers (and other requests) without needing the rest
      of the include files.

      Catherine adds the ability to save the module information from
      get_phy_capabilities() to be used to determine which speeds the module
      supports.  Also cleaned up the PHY structure by removing unused members
      and add the ability to store the PHY capabilities reported by the
      firmware.

      Emil modifies ixgbe to ensure that flow control packets initiated by the
      VF are dropped and reported as spoofed.

      Jacob cleans up the fm10k driver to avoid buffer overflow by using
      sprintf(), so convert to using snprintf().  Also fixed the use of an
      enum as a boolean, so check for the actual value of NETREG_UNINITIALIZED
      in case it ever changes from the current value of zero.

      v2: Dropped patch 11 of the original series, which added functions that
          were never used.

      s390/spinlock: remove unneeded serializations at unlock

      the kernel locks have aqcuire/release semantics. No operation done
      after the lock can be "moved" before the lock and no operation before
      the unlock can be moved after the unlock. But it is perfectly fine
      that memory accesses which happen code wise after unlock are performed
      within the critical section.
      On s390x, reads are in-order with other reads (PoP section
      "Storage-Operand Fetch References") and writes are in-order with
      other writes (PoP section "Storage-Operand Store References"). Writes
      are also in-order with reads to the same memory location (PoP section
      "Storage-Operand Store References"). To other CPUs (and the channel
      subsystem), reads additionally appear to be performed prior to reads or
      writes that happen after them in the conceptual sequence (PoP section
      "Relation between Operand Accesses").
      So at least as observed by other CPUs and the channel subsystem, reads
      inside the critical sections will not happen after unlock (and writes
      are in-order anyway). That's exactly what we need for "RELEASE
      operations" (memory-barriers.txt): "It guarantees that all memory
      operations before the RELEASE operation will appear to happen before the
      RELEASE operation with respect to the other components of the system."

      s390/zcrypt: use explicit return code for flushed requests

      If a AP device is removed while messages are still pending, the requests
      are cancelled by calling the message receive function with an error 
pointer
      for the reply. The message type receive handler recognize this and create
      a fake hardware error TYPE82_RSP_CODE / REP82_ERROR_MACHINE_FAILURE.
      The message with the hardware error then causes a printk and a return
      code of -EAGAIN.

      Replace the intricate scheme with an explicit return code for this 
sitation
      and avoid the error message.

      s390/udelay: make udelay have busy loop semantics

      When using systemtap it was observed that our udelay implementation is
      rather suboptimal if being called from a kprobe handler installed by
      systemtap.

      The problem observed when a kprobe was installed on lock_acquired().
      When the probe was hit the kprobe handler did call udelay, which set
      up an (internal) timer and reenabled interrupts (only the clock comparator
      interrupt) and waited for the interrupt.
      This is an optimization to avoid that the cpu is busy looping while 
waiting
      that enough time passes. The problem is that the interrupt handler still
      does call irq_enter()/irq_exit() which then again can lead to a deadlock,
      since some accounting functions may take locks as well.

      If one of these locks is the same, which caused lock_acquired() to be
      called, we have a nice deadlock.

      This patch reworks the udelay code for the interrupts disabled case to
      immediately leave the low level interrupt handler when the clock
      comparator interrupt happens. That way no C code is being called and the
      deadlock cannot happen anymore.

      s390/cpumf: rework program parameter setting to detect guest samples

      The program parameter can be used to mark hardware samples with
      some token.  Previously, it was used to mark guest samples only.

      Improve the program parameter doubleword by combining two parts,
      the leftmost LPP part and the rightmost PID part.  Set the PID
      part for processes by using the task PID.
      To distinguish host and guest samples for the kernel (PID part
      is zero), the guest must always set the program paramater to a
      non-zero value.  Use the leftmost bit in the LPP part of the
      program parameter to be able to detect guest kernel samples.

      [brueckner@xxxxxxxxxxxxxxxxxx]: Split __LC_CURRENT and introduced

      s390/sclp: avoid merged message output

      The sclp console and tty code currently uses several message text
      objects in a single message event to print several lines with one
      SCCB. This causes the output of these lines to be fused into a
      block which is noticeable when selecting text in the operating system
      message panel.

      Instead use several message events with a single message text object
      each to print every line on its own. This changes the SCCB layout
      from

          struct sccb_header
              struct evbuf_header
                  struct mdb_header
                      struct go
                      struct mto

      s390/entry: add assembler macro to conveniently tests under mask

      Various functions in entry.S perform test-under-mask instructions
      to test for particular bits in memory.  Because test-under-mask uses
      a mask value of one byte, the mask value and the offset into the
      memory must be calculated manually.  This easily introduces errors
      and is hard to review and read.

      Introduce the TSTMSK assembler macro to specify a mask constant and
      let the macro calculate the offset and the byte mask to generate a
      test-under-mask instruction.  The benefit is that existing symbolic
      constants can now be used for tests.  Also the macro checks for
      zero mask values and mask values that consist of multiple bytes.

      s390/fpu: always enable the vector facility if it is available

      If the kernel detects that the s390 hardware supports the vector
      facility, it is enabled by default at an early stage.  To force
      it off, use the novx kernel parameter.  Note that there is a small
      time window, where the vector facility is enabled before it is
      forced to be off.

      With enabling the vector facility by default, the FPU save and
      restore functions can be improved.  They do not longer require
      to manage expensive control register updates to enable or disable
      the vector enablement control for particular processes.

      s390/barrier: avoid serialization in [smp_]rmb and [smp_]wmb

      The principles of operation says:

      The storage-operand fetch references of one instruction
      occur after those of all preceding instructions and
      before those of subsequent instructions, as observed
      by other CPUs and by channel programs.
      [...]
      The CPU may fetch the operands of instructions before the
      instructions are executed.
      [...]
      The CPU may delay placing results in storage.
      [...]
      the results of one instruction are placed in storage after
      the results of all preceding instructions have been placed
      in storage and before any results of the succeeding
      instructions are stored, as observed by other CPUs and by
      the channel subsystem.

      which boils down to:
      - reads are in order
      - writes are in order
      - reads can happen earlier
      - writes can happen later

      By definition (see memory-barrier.txt) read barriers orders
      reads vs reads and write barriers orders writes agains writes.
      but neither of these orders reads vs. writes.

      That means we can implement smp_wmb,smp_rmb,wmb and rmb as
      simple compiler barriers. To avoid reviewing all driver code
      for correct barrier usage we keep dma_[rw]mb as serialization
      for now.

      s390/dasd: mark DASD devices as non rotational

      We were able to reduce the CPU overhead of big paging scenarios
      when announcing our paging disks as non-rotational.
      Almost all dasd devices are implemented in storage servers with

      optimizing the disk schedulers and swap code for a single platter
      moving arm rotational disks. Given the complexity of the setup
      and the fact that this change is mostly to disable the additional
      overhead in swap code, lets keep the other functionality unchanged
      and do not disable the this device as entropy source - unlike other
      non-rotational devices.

      mwifiex: fix AP VHT behaviour

      Even if hostapd configuration file contains VHT parameters,
      they were not getting reflected in beacons. The reason is
      we are resetting them before starting AP. This patch removes
      redundant BSS_STOP and SYS_RESET firmware commands before
      starting AP to fix the problem.

      mwifiex: correction in USB8997 chipset's product ID

      For 8897 chipset, mwifiex_usb unnecessarily used to
      come into picture when wlan is supposed to be used
      via PCIe interface and USB interface is for
      bluetooth.

      This problem has been resolved for newer chipset by
      having separate USB product ids for USB-USB8997 and
      PCIe-USB8997 chipset variants. This patch ensures to
      use wlan specific product id.

      The FreeBSD driver [0] uses the same 2G values as for the AR9280 chips.
      Using the same values in ath9k results in much better throughput for me.

      Before this patch I had a huge amount of packet loss (sometimes up to
      40%) and the max transfer speed was somewhere around 5Mbit/s. With this
      patch applied I have zero packet loss and ten times the throughput.
      My device uses a AR9227 which is the PCI variant of the AR9287.

      I got the idea from some patches from Partik and/or Maarten but those
      moved also the plane state readout to intel_sanitize_crtc() which isn't
      quite right in my opinion.

      There is nothing wrong with the commit per se. We had two versions of
      the commit, one in -next headed for v4.4 and this one for v4.3. Turns
      out we'll need to backport more fixes from -next, and they conflict with
      the v4.3 version. It gets messy. It will be easiest to revert this one,
      and backport all the relevant commits from -next without modifications;
      they apply cleanly after this revert.

      irqchip/mxs: Add Alphascale ASM9260 support

      Freescale iMX23/iMX28 and Alphascale ASM9260 have similar interrupt
      collectors. We already prepared the mxs driver to handle a different

      Differences between these devices:
      - Different register offsets
      - Different count of interupt lines per register
      - ASM9260 does not provide reset bit
      - ASM9260 does not support FIQ.

      irqchip/mxs: Prepare driver for hardware with different offsets

      Alphascale asm9260 has similar functionality but different register
      offsets. To support asm9260 in the mxs driver we need to rework the
      hardcoded access mechanisms.

      - Define SET_REG and CLR_REG. These controllers support seperate CLR and
        SET offsets for each register.

      - Reimplement HW_ICOLL_INTERRUPT with SET_REG and CLR_REG to make it
        usable for both cases.

      - Instead of using icoll_base and adding the offsets at runtime,
        create a new data structure which contains base pointers to all
        required regitsters and use it.

      - Split out functionality, which is required for the init code of mxs
        and asm9260, into helper functions

      Also add an enum to decode the PHY types the NVM is capable of.

      when link is down instead of device id as it will be more accurate.

      When on a backplane device, we do not support changing any settings,
      however we should display all the phy_types we are capable of so if we
      see a backplane dev ID set supported and advertised purely based on
      the phy_types variable.

      i40e/i40evf: Add module_types and update_link_info

      Add a module_types variable to the link_info struct to save the module
      information from get_phy_capabilities. This information can be used to
      determine which speeds the module supports.

      Also add a new function update_link_info which updates the module_types
      parameter and then calls get_link_info. This function should be called
      in place of get_link_info so that the module_types variable stays
      up-to-date with the rest of the link information.

      The EAS table does not reflect the values that are actually returned,
      so instead, basing these values on the Ethernet compliance codes
      specified in table 33 of SFF-8436 as these have been accurate.

      Use the new variable in ethtool to differentiate between a 10G/1G dual
      speed fiber module and a 10G only module.

      i40e: don't panic on VSI allocation failure

      In some circumstances, the firmware may fail to allocate a VSI for a VF.
      When this happens, the driver does not react well to the bad news and
      has a panic attack.

      To fix this problem, check the return value from i40e_alloc_vf_res and
      don't try to configure the device further if it failed. Additionally,
      explicitly clear the INIT bit when we free VF resources, so that this
      bit will be in the proper state in the failure case, and won't blow up
      elsewhere.

      be changed if it is set. Search for and properly remove the filter
      for the old MAC address when the new one is set.

      QCA99X0 uses radio specific board names based on chip id and
      board id combinations. We get these IDs from the target using BMI after

      has been started.

      This patch reorders the call to the function ath10k_core_fetch_board_file
      so that we have OTP binary before requesting for boardid-chipid. We get 
this
      OTP data after parsing firmware-N.bin.

      ath10k: add board 2 API support

      QCA6174 needs different board files based on board type. To make it 
easier to
      distribute multiple board files and automatically choose correct board 
file
      create a simple TLV file format following the same principles as with FW 
IEs.
      The file is named board-2.bin and contain multiple board files. Each 
board file
      then can have multiple names.

      ath10k searches for file board-N.bin (where N is the interface version 
number
      for the board file, just like we for firmware files) in /lib/firmware/*, 
for
      example for qca99x0 it will try to find it here:

      /lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin

      If ath10k doesn't find board-2.bin then it will fallback to the old 
board.bin file.

      This patch adds a simple name scheme using pci device id which for now 
will be
      used by qca6174:

      bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x

      This removes the old method of having subsystem ids in ar->spec_board_id 
and
      using that in the board file name.

      btrfs: fix use after free iterating extrefs

      The code for btrfs inode-resolve has never worked properly for

        btrfs_release_path(path);
        leaf = path->nodes[0];
        item_size = btrfs_item_size_nr(leaf, slot);

      The fix here is to use the extent buffer we cloned just a little higher

      tcp/dccp: fix behavior of stale SYN_RECV request sockets

      When a TCP/DCCP listener is closed, its pending SYN_RECV request sockets
      become stale, meaning 3WHS can not complete.

      But current behavior is wrong :
      incoming packets finding such stale sockets are dropped.

      We need instead to cleanup the request socket and perform another
      lookup :
      - Incoming ACK will give a RST answer,
      - SYN rtx might find another listener if available.
      - We expedite cleanup of request sockets and old listener socket.

      PM / Domains: Fix validation of latency constraints in genpd governor

      Commit ba2bbfbf6307 (PM / Domains: Remove intermediate states from the
      power off sequence) changed the power off sequence in genpd. That also
      required some updates regarding the validation of latency constraints in
      the genpd governor. Unfortunate that wasn't covered, so let's fix this.

      From a runtime PM and latency point of view, we need to consider the worst
      case scenario while validating latency constraints. That's typically when
      a call to pm_runtime_get_sync() needs to wait for a ongoing runtime
      suspend operation to be carried out, as it then also needs to wait for the
      device to be runtime resumed again.

      The above mentioned commit made the genpd governor's ->stop_ok() callback
      responsible of validating genpd's device's runtime suspend/resume latency.
      In other words, the constraint needs to be validated towards the relevant
      latencies present in genpd's ->runtime_suspend|resume() callbacks.

      Earlier, that included latencies from the ->stop|start() callbacks, but as
      ->save|restore_state() are now also being invoked from genpd's
      ->runtime_suspend|resume() and to comply with the worst case scenario,
      let's take also those latencies into account.

      iommu/vt-d: fix range computation when making room for large pages

      In preparation for the installation of a large page, any small page
      tables that may still exist in the target IOV address range are
      removed.  However, if a scatter/gather list entry is large enough to
      fit more than one large page, the address space for any subsequent
      large pages is not cleared of conflicting small page tables.

      This can cause legitimate mapping requests to fail with errors of the
      form below, potentially followed by a series of IOMMU faults:

      ERROR: DMA PTE for vPFN 0xfde00 already set (to 7f83a4003 not 7e9e00083)

      In this example, a 4MiB scatter/gather list entry resulted in the
      successful installation of a large page @ vPFN 0xfdc00, followed by
      a failed attempt to install another large page @ vPFN 0xfde00, due to
      the presence of a pointer to a small page table @ 0x7f83a4000.

      To address this problem, compute the number of large pages that fit
      into a given scatter/gather list entry, and use it to derive the
      last vPFN covered by the large page(s).

      irqchip/gic: Kill the xlate method

      We are now left with only two use models for the GIC driver:
      - Via a firmware interface, which mandates a hierarchical domain,
        and the use of the 'translate' method
      - The legacy platforms, which assume irq==hwirq, hence not using
        the 'xlate' method.

      The logical conclusion is that we can now nuke the 'xlate' method
      altogether.

      irqdomain: Add a fwnode_handle allocator

      In order to be able to reference an irqdomain from ACPI, we need
      to be able to create an identifier, which is usually a struct
      device_node.

      This device node does't really fit the ACPI infrastructure, so
      we cunningly allocate a new structure containing a fwnode_handle,
      and return that.

      This structure doesn't really point to a device (interrupt
      controllers are not "real" devices in Linux), but as we cannot
      really deny that they exist, we create them with a new fwnode_type
      (FWNODE_IRQCHIP).

      Existing functions get rewritten in terms of the new ones so that

      fwnode_handle based as well).

      irqchip: Convert all alloc/xlate users from of_node to fwnode

      Since we now have a generic data structure to express an
      interrupt specifier, convert all hierarchical irqchips that
      are OF based to use a fwnode_handle as part of their alloc
      and xlate (which becomes translate) callbacks.

      As most of these drivers have dependencies (they exchange IRQ
      specifiers), change them all in a single, massive patch...

      irqdomain: Introduce a firmware-specific IRQ specifier structure

      So far the closest thing to a generic IRQ specifier structure is
      of_phandle_args, which happens to be pretty OF specific (the of_node
      pointer in there is quite annoying).

      Let's introduce 'struct irq_fwspec' that can be used in place of
      of_phandle_args for OF, but also for other firmware implementations
      (that'd be ACPI). This is used together with a new 'translate' method
      that is the pendent of 'xlate'.

      We convert irq_create_of_mapping to use this new structure (with a
      small hack that will be removed later).

      So far, our irq domains are still looked up by device node.
      Let's change this and allow a domain to be looked up using

      The existing interfaces are preserved with a couple of helpers.

      Now that we have everyone accessing the of_node field via the

      The struct irq_domain contains a "struct device_node *" field
      (of_node) that is almost the only link between the irqdomain

      By moving the allocation to the caller we also remove the last

      can: avoid using timeval for uapi

      The can subsystem communicates with user space using a bcm_msg_head
      header, which contains two timestamps. This is problematic for
      multiple reasons:

      a) The structure layout is currently incompatible between 64-bit
         user space and 32-bit user space, and cannot work in compat
         mode (other than x32).

      b) The timeval structure layout will change in 32-bit user
         space when we fix the y2038 overflow problem by redefining
         time_t to 64-bit, making new 32-bit user space incompatible
         with the current kernel interface.
         Cars last a long time and often use old kernels, so the actual
         users of this code are the most likely ones to migrate to y2038
         safe user space.

      This tries to work around part of the problem by changing the
      publicly visible user interface in the header, but not the binary
      interface. Fortunately, the values passed around in the structure
      are relative times and do not actually suffer from the y2038
      overflow, so 32-bit is enough here.

      We replace the use of 'struct timeval' with a newly defined
      'struct bcm_timeval' that uses the exact same binary layout
      as before and that still suffers from problem a) but not problem
      b).

      The downside of this approach is that any user space program
      that currently assigns a timeval structure to these members
      rather than writing the tv_sec/tv_usec portions individually
      will suffer a compile-time error when built with an updated
      kernel header. Fixing this error makes it work fine with old
      and new headers though.

      We could address problem a) by using '__u32' or 'int' members
      rather than 'long', but that would have a more significant
      downside in also breaking support for all existing 64-bit user
      binaries that might be using this interface, which is likely
      not acceptable.

      crypto: ahash - ensure statesize is non-zero

      Unlike shash algorithms, ahash drivers must implement export
      and import as their descriptors may contain hardware state and
      cannot be exported as is.  Unfortunately some ahash drivers did
      not provide them and end up causing crashes with algif_hash.

      This patch adds a check to prevent these drivers from registering
      ahash algorithms until they are fixed.

      drm/i915: Deny wrapping an userptr into a framebuffer

      Pinning a userptr onto the hardware raises interesting questions about
      the lifetime of such a surface as the framebuffer extends that life
      beyond the client's address space. That is the hardware will need to
      keep scanning out from the backing storage even after the client wants
      to remap its address space. As the hardware pins the backing storage,
      the userptr becomes invalid and this raises a WARN when the clients
      tries to unmap its address space. The situation can be even more
      complicated when the buffer is passed between processes, between a
      client and display server, where the lifetime and hardware access is
      even more confusing. Deny it.

      drm/i915: Enable DPLL VGA mode before P1/P2 divider write

      Apparently writing the DPLL register P1/P2 divider fields won't trigger
      an actual change in the DPLL output unless VGA mode is enabled for
      prior to the register write that changes the P1/P2 dividers. The write
      with the new P1/P2 divider can itself disable VGA mode again without
      problems.

      I tested the behaviour on my 946GZ, and when manually frobbing the
      register with the display on, the behaviour is very clear. However I
      can't explain why this machine actually works. The P1/P2 divider
      changes caused by normal modesets do seem to make it through to the
      hardware somehow since I get a stable picture on the monitor with
      any resolution. Maybe it's the "three times for luck" stuff that
      somehow masks the problem, or something.

      But apparently there are machines (eg. Nick Bowler's G45) where that
      isn't the case and we fail to get the correct clock from the DPLL.

      Things used to work because we enabled VGA mode for disabled DPLLs,
      so when re-enabling the DPLL VGA mode was enabled just prior to the
      first register write, and hence the P1/P2 change went through without
      a hitch. That got changed in

      b8afb9113c51 drm/i915: Keep GMCH DPLL VGA mode always disabled

      in the name of consistency. In order to keep the consistency part,
      leave VGA mode disabled for disabled DPLLs, but turn it on just prior
      to updating the P1/P2 dividers to make sure the hardware picks up
      on the new values.

      drm/i915: Flush pipecontrol post-sync writes

      In order to flush the results from in-batch pipecontrol writes (used for
      example in glQuery) before declaring the batch complete (and so declaring
      the query results coherent), we need to set the FlushEnable bit in our
      flushing pipecontrol. The FlushEnable bit "waits until all previous
      writes of immediate data from post-sync circles are complete before
      executing the next command".

      I get GPU hangs on byt without flushing these writes (running ue4).
      piglit has examples where the flush is required for correct rendering.

      netfilter: sync with packet rx also after removing queue entries

      We need to sync packet rx again after flushing the queue entries.
      Otherwise, the following race could happen:

      cpu1: nf_unregister_hook(H) called, H unliked from lists, calls
      synchronize_net() to wait for packet rx completion.

      Problem is that while no new nf_queue_entry structs that use H can be
      allocated, another CPU might receive a verdict from userspace just before
      cpu1 calls nf_queue_nf_hook_drop to remove this entry:

      cpu2: receive verdict from userspace, lock queue
      cpu2: unlink nf_queue_entry struct E, which references H, from queue list
      cpu1: calls nf_queue_nf_hook_drop, blocks on queue spinlock
      cpu2: unlock queue
      cpu1: nf_queue_nf_hook_drop drops affected queue entries
      cpu2: call nf_reinject for E
      cpu1: kfree(H)
      cpu2: potential use-after-free for H

      Ido Schimmel reported a problem with switchdev devices because of the
      order change of del_nbp operations, more specifically the move of
      nbp_vlan_flush() which deletes all vlans and frees vlgrp after the
      rx_handler has been unregistered. So in order to fix this move
      vlan_flush back where it was and make it destroy the rhtable after
      NULLing vlgrp and waiting a grace period to make sure noone can see it.

      tcpdump on vrf device and external tap (e.g., host side tap device) shows
      all packets with proper addresses. IPv6 does not need the source address
      operation like IPv4. Verified vti6 works properly in my setup as does use
      of an IPv6 address on the VRF device.

      - added flags to inet6_rtm_getroute (IPv6 version of deaa0a6a930e)

        - if IPV6 is a module, kbuild ensures VRF is a module
        - if IPV6 is disabled IPV6 functionality is compiled out of VRF module
      - addressed comments from Nik over IRC
        - removed duplicate call to netif_is_l3_master in l3mdev_rt6_dst_by_oif

      Furthermore at the point rt6_ifdown is called with dev == NULL no more
      network devices exist in the network namespace so even if the code in
      rt6_uncached_list_flush_dev were to attempt something sensible it
      would be meaningless.

      Therefore remove support in rt6_uncached_list_flush_dev for handling
      network devices where dev == NULL, and only call 
rt6_uncached_list_flush_dev
       when rt6_ifdown is called with a network device.

      bridge: fix gc_timer mod/del race condition

      commit c62987bbd8a1 ("bridge: push bridge setting ageing_time down to
      switchdev") introduced a timer race condition because the gc_timer can
      get rearmed after it's supposedly stopped and flushed in br_dev_delete()
      leading to a use of freed memory. So take rtnl to sync with bridge
      destruction when setting ageing_timer.
      Here's the trace reproduced with these two commands running in parallel:
      while :; do echo 10000 > /sys/class/net/br0/bridge/ageing_timer; done;
      while :; do brctl addbr br0; ip l set br0 up; ip l set br0 down;
      brctl delbr br0; done;

      Merge branch 'be2net-fixes'

      Sathya Perla says:

      ====================
      be2net: patch set

      Patch 1 fixes a FW image compatibility check in the driver that
      prevents certain FW images from being flashed on BE3 (not BE3-R)
      adapters.

      Patch 2 fixes a spin_lock not being released in a failure case in
      be_cmd_notify_wait().

      Patch 3 includes a workaround to pad packets that are only 32b long or 
less
      to be applicabe to BE3 too. This workaround was currently applied only to
      Skyhawk and Lancer chips. Such packets are causing BE3's TX path to stall
      on a SR-IOV config.

      Patch 4 fixes the be_cmd_get_profile_config() routine to set the pf_num
      field in the cmd request. The FW requires this field to be set for it to
      return the specific function's descriptors. If not set, the FW returns
      the descriptors of all the functions on the device. If the first 
descriptor
      is not what is being queried for, the driver will read wrong data.
      This patch fixes this issue by using the GET_CNTL_ATTRIB cmd to query the
      real pci_func_num of a function and then uses it in the GET_PROFILE_CONFIG
      cmd.

      Patch 5 completes an earlier fix that removed the vlan promisc capability
      for VFs. The earlier fix did not update the removal of this capability 
from
      the profile descriptor of the VF. This causes the VF driver to request 
this
      capability when it tries to create it's interface at probe time. This 
could
      potentailly cause the VF probe to fail if the FW enforces strict checking 
of
      the flags based on what was provisoned by the PF.  This strict checking is
      not being done by FW currently but will be fixed in a future version. This
      patch fixes this issue by updating the VF's profile descriptor so that 
they
      match the interface capability flags provisioned by the PF.

      Pls consider adding these patches to the net tree. Thanks!

      be2net: remove vlan promisc capability from VF's profile descriptors

      The commit 435452aa8847 ("Prevent VFs from enabling VLAN promiscuous 
mode")
      fixed the PF driver to not include the VLAN promisc capability while
      provisioning the interface for a VF. But the fix did not remove this
      capability from the profile descriptor of the VF. This causes the VF
      driver to request this capability when it tries to create it's interface

      be2net: fix BE3-R FW download compatibility check

      In the BE3 FW image, unlike Skyhawk's, the "asic_type_rev" field doesn't
      track the asic_rev of chip it is compatible with. When asic_type_rev
      is 0 the image is compatible only with pre-BE3-R chips (asic_rev < 0x10).
      Fix the current compatibility check to take care of this.
      We hit this issue when we try to flash old BE3 images (used prior to the
      release of BE3-R) on pre-BE3-R adapters.

      net/fsl_pq_mdio: fix computed address for the TBI register

      commit afae5ad78b342f401c28b0bb1adb3cd494cb125a
        "net/fsl_pq_mdio: streamline probing of MDIO nodes"

      added support for different types of MDIO devices:
      1) Gianfar MDIO nodes that only map the MII registers
      2) Gianfar MDIO nodes that map the full MDIO register set
      3) eTSEC2 MDIO nodes (which map the full MDIO register set)
      4) QE MDIO nodes (which map only the MII registers)

      However, the implementation for types 1 and 4 would mistakenly assume
      a mapping of the full MDIO register set, thereby computing the address
      for the TBI register starting from the containing structure.
      The TBI register would therefore be accessed at a wrong (much bigger)
      address, not giving the expected result at all.
      This patch restores the correct behavior we had prior to the above one.

      The consequences of this bug are apparent when trying to access a PHY
      with the same address as the value contained in the initial value of
      the TBI register (normally 0); in that case you'll get answers from the
      internal TBI device (even though MDIO/MDC pins are actually *also*
      toggling on the physical bus!).
      Beware that you also need to add a fake tbi node to your device tree
      with an unused address.

      Notice how this fix is related to commit
      220669495bf8b68130a8218607147c7b74c28d2b
        "powerpc: Add TBI PHY node to first MDIO bus"

      which fixed the behavior in kernel 3.3, which was later broken by the
      above commit on kernel 3.7.

      net/fsl_pq_mdio: check TBI address for consistency with mapped range

      When configuring the MDIO subsystem it is also necessary to configure
      the TBI register. Make sure the TBI is contained within the mapped
      register range in order to:
      a) make sure the address is computed correctly

      ====================
      net: dsa: mv88e6xxx: fix hardware bridging

      DSA and its drivers currently hook the NETDEV_CHANGEUPPER net_device 
event in
      order to configure the VLAN map of every port.

      This VLAN map is a feature of these switch chips to hardcode and restrict 
which
      output ports a given input port can egress frames to.

      A Linux bridge is a simple untagged VLAN propagated by the bridge code 
itself.
      With a proper 802.1Q support, a driver does not need this hook anymore, 
and
      will simply program the related VLAN object.

      This patchset improves the hardware bridging code in the mv88e6xxx driver 
with
      a strict 802.1Q mode.

      Ideally, the equivalent must be done for Broadcom Starfighter 2 and 
Rocker,
      before completely getting rid of this hook.

      net: dsa: mv88e6xxx: fix hardware bridging

      Playing with the VLAN map of every port to implement "hardware bridging"
      in the 88E6352 driver was a hack until full 802.1Q was supported.

      Indeed with 802.1Q port mode "Disabled" or "Fallback", this feature is
      used to restrict which output ports an input port can egress frames to.

      A Linux bridge is an untagged VLAN. With full 802.1Q support, we don't
      need this hack anymore and can use the "Secure" strict 802.1Q port mode.

      With this mode, the port-based VLAN map still needs to be configured,
      but all the logic is VTU-centric. This means that the switch only cares
      about rules described in its hardware VLAN table, which is exactly what
      Linux bridge expects and what we want.

      Note also that the hardware bridging was broken with the previous
      flexible "Fallback" 802.1Q port mode. Here's an example:

      Port0 and Port1 belong to the same bridge. If Port0 sends crafted tagged
      frames with VID 200 to Port1, Port1 receives it. Even if Port1 is in
      hardware VLAN 200, but not Port0, Port1 will still receive it, because
      Fallback mode doesn't care about invalid VID or non-member source port.

      net: dsa: mv88e6xxx: do not support per-port FID

      Since we configure a switch chip through a Linux bridge, and a bridge is
      implemented as a VLAN, there is no need for per-port FID anymore.

      This patch gets rid of this and simplifies the driver code since we can
      now directly map all 4095 FIDs available to all VLANs.

      net: dsa: mv88e6xxx: bridges do not need an FID

      With 88E6352 and similar switch chips, each port has a map to restrict
      which output port this input port can egress frames to.

      The current driver code implements hardware bridging using this feature,
      and assigns to a bridge group the FID of its first member.

      Now that 802.1Q is fully implemented in this driver, a Linux bridge
      which is a simple untagged VLAN, already gets its own FID.

      This patch gets rid of the per-bridge FID and explicits the usage of the
      port based VLAN map feature.

      RDS-TCP: Reset tcp callbacks if re-using an outgoing socket in 
rds_tcp_accept_one()

      Consider the following "duelling syn" sequence between two peers A and B:
                A               B
                SYN1     -->
                        <--     SYN2
                SYN2ACK  -->

      Note that the SYN/ACK has already been sent out by TCP before
      rds_tcp_accept_one() gets invoked as part of callbacks.

      If the inet_addr(A) is numerically less than inet_addr(B),
      the arbitration scheme in rds_tcp_accept_one() will prefer the
      TCP connection triggered by SYN1, and will send a CLOSE for the
      SYN2 (just after the SYN2ACK was sent).

      Since B also follows the same arbitration scheme, it will send the SYN-ACK
      for SYN1 that will set up a healthy ESTABLISHED connection on both sides.
      B will also get a  CLOSE for SYN2, which should result in the cleanup
      of the TCP state machine for SYN2, but it should not trigger any
      stale RDS-TCP callbacks (such as ->writespace, ->state_change etc),
      that would disrupt the progress of the SYN2 based RDS-TCP  connection.

      Thus the arbitration scheme in rds_tcp_accept_one() should restore
      rds_tcp callbacks for the winner before setting them up for the
      new accept socket, and also make sure that conn->c_outgoing
      is set to 0 so that we do not trigger any reconnect attempts on the
      passive side of the tcp socket in the future, in conformance with
      commit c82ac7e69efe ("net/rds: RDS-TCP: only initiate reconnect attempt
      on outgoing TCP socket.")

      netfilter: nfqueue: don't use prev pointer

      Usage of -prev seems buggy.  While packet was out our hook cannot be
      removed but we have no way to know if the previous one is still valid.

      So better not use ->prev at all.  Since NF_REPEAT just asks to invoke
      same hook function again, just do so, and continue with nf_interate
      if we get an ACCEPT verdict.

      A side effect of this change is that if nf_reinject(NF_REPEAT) causes
      another REPEAT we will now drop the skb instead of a kernel loop.

      However, NF_REPEAT loops would be a bug so this should not happen anyway.

      cfg80211: Add multiple scan plans for scheduled scan

      Add the option to configure multiple 'scan plans' for scheduled scan.
      Each 'scan plan' defines the number of scan cycles and the interval
      between scans. The scan plans are executed in the order they were
      configured. The last scan plan will always run infinitely and thus
      defines only the interval between scans.
      The maximum number of scan plans supported by the device and the
      maximum number of iterations in a single scan plan are advertised
      to userspace so it can configure the scan plans appropriately.

      When scheduled scan results are received there is no way to know which
      scan plan is being currently executed, so there is no way to know when
      the next scan iteration will start. This is not a problem, however.
      The scan start timestamp is only used for flushing old scan results,
      and there is no difference between flushing all results received until
      the end of the previous iteration or the start of the current one,
      since no results will be received in between.

      nl80211: allow BSS data to include CLOCK_BOOTTIME timestamp

      For location and connectivity services, userspace would often like
      to know the time when the BSS was last seen. The current "last seen"
      value is calculated in a way that makes it less useful, especially
      if the system suspended in the meantime.

      Add the ability for the driver to report a real CLOCK_BOOTTIME stamp
      that can then be reported to userspace (if present).

      Drivers wishing to use this must be converted to the new API to call
      cfg80211_inform_bss_data() or cfg80211_inform_bss_frame_data(). They
      need to ensure the reported value is accurate enough even when the
      frame might have been buffered in the device (e.g. firmware.)

      net: Pass net into defragmentation

      This is the next installment of my work to pass struct net through the
      output path so the code does not need to guess how to figure out which
      network namespace it is in, and ultimately routes can have output
      devices in another network namespace.

      In netfilter and af_packet we defragment packets in the output path,
      and there is the usual amount of confusion about how to compute which
      net we are processing the packets in.  This patchset clears that
      confusion up by explicitly passing in struct net in ip_defrag,
      ip_check_defrag, and nf_ct_frag6_gather.

      ipv6: Pass struct net into nf_ct_frag6_gather

      The function nf_ct_frag6_gather is called on both the input and the

      calls nf_ct_frag6_gather is called from both the the PRE_ROUTING chain
      on input and the LOCAL_OUT chain on output.

      The addition of a net parameter makes it explicit which network
      namespace the packets are being reassembled in, and removes the need
      for nf_ct_frag6_gather to guess.

      packet: fix match_fanout_group()

      Recent TCP listener patches exposed a prior af_packet bug :
      match_fanout_group() blindly assumes it is always safe
      to cast sk to a packet socket to compare fanout with af_packet_priv

      But SYNACK packets can be sent while attached to request_sock, which
      are smaller than a "struct sock".

      ipv4/icmp: redirect messages can use the ingress daddr as source

      This patch allows configuring how the source address of ICMP
      redirect messages is selected; by default the old behaviour is
      retained, while setting icmp_redirects_use_orig_daddr force the
      usage of the destination address of the packet that caused the
      redirect.

      The new behaviour fits closely the RFC 5798 section 8.1.1, and fix the
      following scenario:

      Two machines are set up with VRRP to act as routers out of a subnet,
      they have IPs x.x.x.1/24 and x.x.x.2/24, with VRRP holding on to
      x.x.x.254/24.

      If a host in said subnet needs to get an ICMP redirect from the VRRP
      router, i.e. to reach a destination behind a different gateway, the
      source IP in the ICMP redirect is chosen as the primary IP on the
      interface that the packet arrived at, i.e. x.x.x.1 or x.x.x.2.

      The host will then ignore said redirect, due to RFC 1122 section 3.2.2.2,
      and will continue to use the wrong next-op.

      net: align sk_refcnt on 128 bytes boundary

      sk->sk_refcnt is dirtied for every TCP/UDP incoming packet.
      This is a performance issue if multiple cpus hit a common socket,
      or multiple sockets are chained due to SO_REUSEPORT.

      By moving sk_refcnt 8 bytes further, first 128 bytes of sockets
      are mostly read. As they contain the lookup keys, this has
      a considerable performance impact, as cpus can cache them.

      These 8 bytes are not wasted, we use them as a place holder
      for various fields, depending on the socket type.

      Tested:
       SYN flood hitting a 16 RX queues NIC.
       TCP listener using 16 sockets and SO_REUSEPORT
       and SO_INCOMING_CPU for proper siloing.

       Could process 6.0 Mpps SYN instead of 4.2 Mpps

      net: SO_INCOMING_CPU setsockopt() support

      SO_INCOMING_CPU as added in commit 2c8c56e15df3 was a getsockopt() command
      to fetch incoming cpu handling a particular TCP flow after accept()

      This commits adds setsockopt() support and extends SO_REUSEPORT selection
      logic : If a TCP listener or UDP socket has this option set, a packet is
      delivered to this socket only if CPU handling the packet matches the 
specified
      one.

      This allows to build very efficient TCP servers, using one listener per
      RX queue, as the associated TCP listener should only accept flows handled
      in softirq by the same cpu.
      This provides optimal NUMA behavior and keep cpu caches hot.

      Note that __inet_lookup_listener() still has to iterate over the list of
      all listeners. Following patch puts sk_refcnt in a different cache line
      to let this iteration hit only shared and read mostly cache lines.

      Merge branch 'bpf-unprivileged'

      Alexei Starovoitov says:

      ====================
      bpf: unprivileged

      v1-v2:
      - this set logically depends on cb patch
        "bpf: fix cb access in socket filter programs":
        http://patchwork.ozlabs.org/patch/527391/
        which is must have to allow unprivileged programs.
        Thanks Daniel for finding that issue.
      - refactored sysctl to be similar to 'modules_disabled'
      - dropped bpf_trace_printk
      - split tests into separate patch and added more tests
        based on discussion

      v1 cover letter:
      I think it is time to liberate eBPF from CAP_SYS_ADMIN.
      As was discussed when eBPF was first introduced two years ago
      the only piece missing in eBPF verifier is 'pointer leak detection'
      to make it available to non-root users.
      Patch 1 adds this pointer analysis.
      The eBPF programs, obviously, need to see and operate on kernel addresses,
      but with these extra checks they won't be able to pass these addresses
      to user space.
      Patch 2 adds accounting of kernel memory used by programs and maps.
      It changes behavoir for existing root users, but I think it needs
      to be done consistently for both root and non-root, since today
      programs and maps are only limited by number of open FDs (RLIMIT_NOFILE).
      Patch 2 accounts program's and map's kernel memory as RLIMIT_MEMLOCK.

      Unprivileged eBPF is only meaningful for 'socket filter'-like programs.
      eBPF programs for tracing and TC classifiers/actions will stay root only.

      In parallel the bpf fuzzing effort is ongoing and so far
      we've found only one verifier bug and that was already fixed.
      The 'constant blinding' pass also being worked on.
      It will obfuscate constant-like values that are part of eBPF ISA
      to make jit spraying attacks even harder.

      bpf: add unprivileged bpf tests

      Add new tests samples/bpf/test_verifier:

      unpriv: return pointer
        checks that pointer cannot be returned from the eBPF program

      unpriv: add const to pointer
      unpriv: add pointer to pointer
      unpriv: neg pointer
        checks that pointer arithmetic is disallowed

      unpriv: cmp pointer with const
      unpriv: cmp pointer with pointer
        checks that comparison of pointers is disallowed
        Only one case allowed 'void *value = bpf_map_lookup_elem(..); if (value 
== 0) ...'

      unpriv: check that printk is disallowed
        since bpf_trace_printk is not available to unprivileged

      unpriv: pass pointer to helper function
        checks that pointers cannot be passed to functions that expect integers
        If function expects a pointer the verifier allows only that type of 
pointer.
        Like 1st argument of bpf_map_lookup_elem() must be pointer to map.
        (applies to non-root as well)

      unpriv: indirectly pass pointer on stack to helper function
        checks that pointer stored into stack cannot be used as part of key
        passed into bpf_map_lookup_elem()

      unpriv: mangle pointer on stack 1
      unpriv: mangle pointer on stack 2
        checks that writing into stack slot that already contains a pointer
        is disallowed

      unpriv: read pointer from stack in small chunks
        checks that < 8 byte read from stack slot that contains a pointer is
        disallowed

      unpriv: write pointer into ctx
        checks that storing pointers into skb->fields is disallowed

      unpriv: write pointer into map elem value
        checks that storing pointers into element values is disallowed
        For example:
        int bpf_prog(struct __sk_buff *skb)
        {
          u32 key = 0;
          u64 *value = bpf_map_lookup_elem(&map, &key);
          if (value)
             *value = (u64) skb;
        }
        will be rejected.

      unpriv: partial copy of pointer
        checks that doing 32-bit register mov from register containing
        a pointer is disallowed

      unpriv: pass pointer to tail_call
        checks that passing pointer as an index into bpf_tail_call
        is disallowed

      unpriv: cmp map pointer with zero
        checks that comparing map pointer with constant is disallowed

      unpriv: write into frame pointer
        checks that frame pointer is read-only (applies to root too)

      unpriv: cmp of frame pointer
        checks that R10 cannot be using in comparison

      unpriv: cmp of stack pointer
        checks that Rx = R10 - imm is ok, but comparing Rx is not

      unpriv: obfuscate stack pointer
        checks that Rx = R10 - imm is ok, but Rx -= imm is not

      bpf: charge user for creation of BPF maps and programs

      since eBPF programs and maps use kernel memory consider it 'locked' memory
      from user accounting point of view and charge it against RLIMIT_MEMLOCK 
limit.
      This limit is typically set to 64Kbytes by distros, so almost all
      bpf+tracing programs would need to increase it, since they use maps,
      but kernel charges maximum map size upfront.
      For example the hash map of 1024 elements will be charged as 64Kbyte.
      It's inconvenient for current users and changes current behavior for root,
      but probably worth doing to be consistent root vs non-root.

      Similar accounting logic is done by mmap of perf_event.

      bpf: enable non-root eBPF programs

      In order to let unprivileged users load and execute eBPF programs
      teach verifier to prevent pointer leaks.
      Verifier will prevent
      - any arithmetic on pointers
        (except R10+Imm which is used to compute stack addresses)
      - comparison of pointers
        (except if (map_value_ptr == 0) ... )
      - passing pointers to helper functions
      - indirectly passing pointers in stack to helper functions
      - returning pointer from bpf program
      - storing pointers into ctx or maps

      Spill/fill of pointers into stack is allowed, but mangling
      of pointers stored in the stack or reading them byte by byte is not.

      Within bpf programs the pointers do exist, since programs need to
      be able to access maps, pass skb pointer to LD_ABS insns, etc
      but programs cannot pass such pointer values to the outside
      or obfuscate them.

      Only allow BPF_PROG_TYPE_SOCKET_FILTER unprivileged programs,
      so that socket filters (tcpdump), af_packet (quic acceleration)
      and future kcm can use it.
      tracing and tc cls/act program types still require root permissions,
      since tracing actually needs to be able to see all kernel pointers
      and tc is for root only.

      For example, the following unprivileged socket filter program is allowed:
      int bpf_prog1(struct __sk_buff *skb)
      {
        u32 index = load_byte(skb, ETH_HLEN + offsetof(struct iphdr, protocol));
        u64 *value = bpf_map_lookup_elem(&my_map, &index);

        if (value)
        *value += skb->len;
        return 0;
      }

      but the following program is not:
      int bpf_prog1(struct __sk_buff *skb)
      {
        u32 index = load_byte(skb, ETH_HLEN + offsetof(struct iphdr, protocol));
        u64 *value = bpf_map_lookup_elem(&my_map, &index);

        if (value)
        *value += (u64) skb;
        return 0;
      }
      since it would leak the kernel address into the map.

      Unprivileged socket filter bpf programs have access to the
      following helper functions:
      - map lookup/update/delete (but they cannot store kernel pointers into 
them)
      - get_random (it's already exposed to unprivileged user space)
      - get_smp_processor_id
      - tail_call into another socket filter program
      - ktime_get_ns

      The feature is controlled by sysctl kernel.unprivileged_bpf_disabled.
      This toggle defaults to off (0), but can be set true (1).  Once true,
      bpf programs and maps cannot be accessed from unprivileged process,
      and the toggle cannot be set back to false.

      memory: omap-gpmc: Fix unselectable debug option for GPMC

      Commit 63aa945b1013 ("memory: omap-gpmc: Add Kconfig option for debug")
      added a debug option for GPMC, but somehow managed to keep it 
unselectable.

      This probably happened because I had some uncommitted changes and the
      GPMC option is selected in the platform specific Kconfig.

      Let's also update the description a bit, it does not mention that
      enabling the debug option also disables the reset of GPMC controller
      during the init as pointed out by Uwe Kleine-König
      <u.kleine-koenig@xxxxxxxxxxxxxx> and Roger Quadros <rogerq@xxxxxx>.

      ARM: dts: am57xx-beagle-x15: set VDD_SD to always-on

      LDO1 regulator (VDD_SD) is connected to SoC's vddshv8. vddshv8 needs to
      be kept always powered (see commit 5a0f93c6576a ("ARM: dts: Add
      am57xx-beagle-x15"), but at the moment VDD_SD is enabled/disabled
      depending on whether an SD card is inserted or not.

      This patch sets LDO1 regulator to always-on.

      This patch has a side effect of fixing another issue, HDMI DDC not
      working when SD card is not inserted:

      Why this happens is that the tpd12s015 (HDMI level shifter/ESD
      protection chip) has LS_OE GPIO input, which needs to be enabled for the
      HDMI DDC to work. LS_OE comes from gpio6_28. The pin that provides
      gpio6_28 is powered by vddshv8, and vddshv8 comes from VDD_SD.

      So when SD card is not inserted, VDD_SD is disabled, and LS_OE stays
      off.

      The proper fix for the HDMI DDC issue would be to maybe have the pinctrl
      framework manage the pin specific power.

      Apparently this fixes also a third issue (copy paste from Kishon's
      patch):

      ldo1_reg in addition to being connected to the io lines is also
      connected to the card detect line. On card removal, omap_hsmmc
      driver does a regulator_disable causing card detect line to be
      pulled down. This raises a card insertion interrupt and once the
      MMC core detects there is no card inserted, it does a
      regulator disable which again raises a card insertion interrupt.
      This happens in a loop causing infinite MMC interrupts.

      nvme: fix 32-bit build warning

      Compiling the nvme driver on 32-bit warns about a cast from a __u64
      variable to a pointer:

      drivers/block/nvme-core.c: In function 'nvme_submit_io':

of different size [-Wint-to-pointer-cast]
          (void __user *)io.addr, length, NULL, 0);

      The cast here is intentional and safe, so we can shut up the
      gcc warning by adding an intermediate cast to 'uintptr_t'.

      I had previously submitted a patch to fix this problem in the
      nvme driver, but it was accepted on the same day that two new
      warnings got added.

      For clarification, I also change the third instance of this cast
      to use uintptr_t instead of unsigned long now.

      perf hists browser: Inform how to reset the symbol filter

      When in the hists browser, i.e. in 'perf report' or in 'perf top', it is
      possible to press '/' and specify a substring to filter by symbol name.

      Clarify how to remove a filter by making the prompt be:

         Please enter the name of symbol you want to see.
         To remove the filter later, press / + ENTER

      arm64: add KASAN support

      This patch adds arch specific code for kernel address sanitizer
      (see Documentation/kasan.txt).

      1/8 of kernel addresses reserved for shadow memory. There was no
      big enough hole for this, so virtual addresses for shadow were
      stolen from vmalloc area.

      At early boot stage the whole shadow region populated with just
      one physical page (kasan_zero_page). Later, this page reused
      as readonly zero shadow for some memory that KASan currently
      don't track (vmalloc).
      After mapping the physical memory, pages for shadow memory are
      allocated and mapped.

      Functions like memset/memmove/memcpy do a lot of memory accesses.
      If bad pointer passed to one of these function it is important
      to catch this. Compiler's instrumentation cannot do this since
      these functions are written in assembly.
      KASan replaces memory functions with manually instrumented variants.
      Original functions declared as weak symbols so strong definitions
      in mm/kasan/kasan.c could replace them. Original functions have aliases
      with '__' prefix in name, so we could call non-instrumented variant
      if needed.
      Some files built without kasan instrumentation (e.g. mm/slub.c).
      Original mem* function replaced (via #define) with prefixed variants
      to disable memory access checks for such files.

      arm64: Fix MINSIGSTKSZ and SIGSTKSZ

      MINSIGSTKSZ and SIGSTKSZ for ARM64 are not correctly set in latest kernel.
      This patch fixes this issue.

      This issue is reported in LTP (testcase: sigaltstack02.c).
      Testcase failed when sigaltstack() called with stack size "MINSIGSTKSZ - 
1"
      Since in Glibc-2.22, MINSIGSTKSZ is set to 5120 but in kernel
      it is set to 2048 so testcase gets failed.

      Testcase Output:
      sigaltstack02 1  TPASS  :  stgaltstack() fails, Invalid Flag 
value,errno:22
      sigaltstack02 2  TFAIL  :  sigaltstack() returned 0, expected -1,errno:12

      Commit df057cc7b4fa ("arm64: errata: add module build workaround for

      model is used by the compiler when building kernel modules.

      However, CFLAGS_MODULE is an environment variable and intended to be
      overridden on the command line, which appears to be the case with the
      Ubuntu kernel packaging system, so use KBUILD_CFLAGS_MODULE instead.

      writeback: fix incorrect calculation of available memory for memcg domains

      For memcg domains, the amount of available memory was calculated as

       min(the amount currently in use + headroom according to memcg,
           total clean memory)

      This isn't quite correct as what should be capped by the amount of
      clean memory is the headroom, not the sum of memory in use and
      headroom.  For example, if a memcg domain has a significant amount of
      dirty memory, the above can lead to a value which is lower than the
      current amount in use which doesn't make much sense.  In most
      circumstances, the above leads to a number which is somewhat but not
      drastically lower.

      As the amount of memory which can be readily allocated to the memcg
      domain is capped by the amount of system-wide clean memory which is
      not already assigned to the memcg itself, the number we want is

       the amount currently in use +
       min(headroom according to memcg, clean memory elsewhere in the system)

      This patch updates mem_cgroup_wb_stats() to return the number of
      filepages and headroom instead of the calculated available pages.
      mdtc_cap_avail() is renamed to mdtc_calc_avail() and performs the
      above calculation from file, headroom, dirty and globally clean pages.

      v2: Dummy mem_cgroup_wb_stats() implementation wasn't updated leading
          to build failure when !CGROUP_WRITEBACK.  Fixed.

      writeback: memcg dirty_throttle_control should be initialized with 
wb->memcg_completions

      MDTC_INIT() is used to initialize dirty_throttle_control for memcg
      domains.  It used DTC_INIT_COMMON() to initialized mdtc->wb and
      ->wb_completions which is incorrect as DTC_INIT_COMMON() sets the
      latter to wb->completions instead of wb->memcg_completions.  This can
      lead to wildly incorrect results when calculating the proportion of
      dirty memory the memcg domain should get.

      mdtc->wb_completions to wb->memcg_completions.

      writeback: bdi_writeback iteration must not skip dying ones

      bdi_for_each_wb() is used in several places to wake up or issue
      writeback work items to all wb's (bdi_writeback's) on a given bdi.
      The iteration is performed by walking bdi->cgwb_tree; however, the
      tree only indexes wb's which are currently active.

      For example, when a memcg gets associated with a different blkcg, the
      old wb is removed from the tree so that the new one can be indexed.
      The old wb starts dying from then on but will linger till all its
      inodes are drained.  As these dying wb's may still host dirty inodes,
      writeback operations which affect all wb's must include them.
      bdi_for_each_wb() skipping dying wb's led to sync(2) missing and
      failing to sync the inodes belonging to those wb's.

      This patch adds a RCU protected @bdi->wb_list which lists all wb's
      beloinging to that bdi.  wb's are added on creation and removed on
      release rather than on the start of destruction.  bdi_for_each_wb()
      usages are replaced with list_for_each[_continue]_rcu() iterations
      over @bdi->wb_list and bdi_for_each_wb() and its helpers are removed.

      v2: Updated as per Jan.  last_wb ref leak in bdi_split_work_to_wbs()
          fixed and unnecessary list head severing in cgwb_bdi_destroy()
          removed.

      svcrdma: Fix NFS server crash triggered by 1MB NFS WRITE

      Now that the NFS server advertises a maximum payload size of 1MB
      for RPC/RDMA again, it crashes in svc_process_common() when NFS
      client sends a 1MB NFS WRITE on an NFS/RDMA mount.

      The server has set up a 259 element array of struct page pointers
      in rq_pages[] for each incoming request. The last element of the
      array is NULL.

      When an incoming request has been completely received,
      rdma_read_complete() attempts to set the starting page of the
      incoming page vector:

        rqstp->rq_arg.pages = &rqstp->rq_pages[head->hdr_count];

      and the page to use for the reply:

        rqstp->rq_respages = &rqstp->rq_arg.pages[page_no];

      But the value of page_no has already accounted for head->hdr_count.
      Thus rq_respages now points past the end of the incoming pages.

      For NFS WRITE operations smaller than the maximum, this is harmless.
      But when the NFS WRITE operation is as large as the server's max
      payload size, rq_respages now points at the last entry in rq_pages,
      which is NULL.

      netfilter: bridge: avoid unused label warning

      With the ARM mini2440_defconfig, the bridge netfilter code gets
      built with both CONFIG_NF_DEFRAG_IPV4 and CONFIG_NF_DEFRAG_IPV6
      disabled, which leads to a harmless gcc warning:

      net/bridge/br_netfilter_hooks.c: In function 'br_nf_dev_queue_xmit':
      net/bridge/br_netfilter_hooks.c:792:2: warning: label 'drop' defined but 
not used [-Wunused-label]

      This gets rid of the warning by cleaning up the code to avoid
      the respective #ifdefs causing this problem, and replacing them
      with if(IS_ENABLED()) checks. I have verified that the resulting
      object code is unchanged, and an additional advantage is that
      we now get compile coverage of the unused functions in more
      configurations.

      netfilter: ipt_rpfilter: remove the nh_scope test in 
rpfilter_lookup_reverse

      --accept-local  option works for res.type == RTN_LOCAL, which should be
      from the local table, but there, the fib_info's nh->nh_scope =
      RT_SCOPE_NOWHERE ( > RT_SCOPE_HOST). in fib_create_info().

        if (cfg->fc_scope == RT_SCOPE_HOST) {
                struct fib_nh *nh = fi->fib_nh;

                /* Local address is added. */
                if (nhs != 1 || nh->nh_gw)
                        goto err_inval;
                nh->nh_scope = RT_SCOPE_NOWHERE;   <===
                nh->nh_dev = dev_get_by_index(net, fi->fib_nh->nh_oif);
                err = -ENODEV;
                if (!nh->nh_dev)
                        goto failure;

      but in our rpfilter_lookup_reverse():

        if (dev_match || flags & XT_RPFILTER_LOOSE)
                return FIB_RES_NH(res).nh_scope <= RT_SCOPE_HOST;

      if nh->nh_scope > RT_SCOPE_HOST, it will fail. --accept-local option
      will never be passed.

      it seems the test is bogus and can be removed to fix this issue.

        if (dev_match || flags & XT_RPFILTER_LOOSE)
                return FIB_RES_NH(res).nh_scope <= RT_SCOPE_HOST;

      arm64/efi: isolate EFI stub from the kernel proper

      Since arm64 does not use a builtin decompressor, the EFI stub is built
      into the kernel proper. So far, this has been working fine, but actually,
      since the stub is in fact a PE/COFF relocatable binary that is executed
      at an unknown offset in the 1:1 mapping provided by the UEFI firmware, we
      should not be seamlessly sharing code with the kernel proper, which is a
      position dependent executable linked at a high virtual offset.

      So instead, separate the contents of libstub and its dependencies, by
      putting them into their own namespace by prefixing all of its symbols
      with __efistub. This way, we have tight control over what parts of the
      kernel proper are referenced by the stub.

      For more control over which functions are called with the MMU off or
      with the UEFI 1:1 mapping active, annotate some assembler routines as

      netfilter: conntrack: fix crash on timeout object removal

      The object and module refcounts are updated for each conntrack template,
      however, if we delete the iptables rules and we flush the timeout
      database, we may end up with invalid references to timeout object that
      are just gone.

      Resolve this problem by setting the timeout reference to NULL when the
      custom timeout entry is removed from our base. This patch requires some
      RCU trickery to ensure safe pointer handling.

      This handling is similar to what we already do with conntrack helpers,
      the idea is to avoid bumping the timeout object reference counter from
      the packet path to avoid the cost of atomic ops.

      Pave the way for checking the current patch level of the

      But that will be added in a later patch.

      Drop unused local var uci assignment, while at it.

      Integrate a fix for 32-bit and CONFIG_PARAVIRT from Takashi Iwai:

       Use native_rdmsr() in check_current_patch_level() because with
       CONFIG_PARAVIRT enabled and on 32-bit, where we run before
       paging has been enabled, we cannot deref pv_info yet. Or we
       could, but we'd need to access its physical address. This way of
       fixing it is simpler. See:

      x86/ras/mce_amd_inj: Return early on invalid input

      Invalid inputs such as these are currently reported in dmesg as
      failing:

        $> echo sweet > flags
        [  122.079139] flags_write: Invalid flags value: et

      even though the 'flags' attribute has been updated correctly:

        $> cat flags
        sw

      This is because userspace keeps writing the remaining buffer
      until it encounters an error.

      However, the input as a whole is wrong and we should not be
      writing anything to the file. Therefore, correct flags_write()
      to return -EINVAL immediately on bad input strings.

      ovl: fix open in stacked overlay

      If two overlayfs filesystems are stacked on top of each other, then we 
need
      recursion in ovl_d_select_inode().

      I guess d_backing_inode() is supposed to do that.  But currently it 
doesn't
      and that functionality is open coded in vfs_open().  This is now copied
      into ovl_d_select_inode() to fix this regression.

      ovl: fix dentry reference leak

      In ovl_copy_up_locked(), newdentry is leaked if the function exits through
      out_cleanup as this just to out after calling ovl_cleanup() - which 
doesn't
      actually release the ref on newdentry.

      The out_cleanup segment should instead exit through out2 as certainly
      newdentry leaks - and possibly upper does also, though this isn't caught
      given the catch of newdentry.

      Without this fix, something like the following is seen:

        BUG: Dentry ffff880023e9eb20{i=f861,n=#ffff880023e82d90} still in use 
(1) [unmount of tmpfs tmpfs]
        BUG: Dentry ffff880023ece640{i=0,n=bigfile}  still in use (1) [unmount 
of tmpfs tmpfs]

      when unmounting the upper layer after an error occurred in copyup.

      An error can be induced by creating a big file in a lower layer with
      something like:

        dd if=/dev/zero of=/lower/a/bigfile bs=65536 count=1 seek=$((0xf000))

      to create a large file (4.1G).  Overlay an upper layer that is too small
      (on tmpfs might do) and then induce a copy up by opening it writably.

      efi: Add "efi_fake_mem" boot option

      This patch introduces new boot option named "efi_fake_mem".
      By specifying this parameter, you can add arbitrary attribute
      to specific memory range.
      This is useful for debugging of Address Range Mirroring feature.

      For example, if "efi_fake_mem=2G@4G:0x10000,2G@0x10a0000000:0x10000"
      is specified, the original (firmware provided) EFI memmap will be

      EFI_MEMORY_MORE_RELIABLE attribute (0x10000):

      efifb: Add support for 64-bit frame buffer addresses

      The EFI Graphics Output Protocol uses 64-bit frame buffer addresses
      but these get truncated to 32-bit by the EFI boot stub when storing
      the address in the 'lfb_base' field of 'struct screen_info'.

      Add a 'ext_lfb_base' field for the upper 32-bits of the frame buffer
      address and set VIDEO_TYPE_CAPABILITY_64BIT_BASE when the field is
      useable.

      It turns out that the reason no one has required this support so far
      is that there's actually code in tianocore to "downgrade" PCI
      resources that have option ROMs and 64-bit BARS from 64-bit to 32-bit
      to cope with legacy option ROMs that can't handle 64-bit addresses.
      The upshot is that basically all GOP devices in the wild use a 32-bit
      frame buffer address.

      Still, it is possible to build firmware that uses a full 64-bit GOP
      frame buffer address. Chad did, which led to him reporting this issue.

      Add support in anticipation of GOP devices using 64-bit addresses more
      widely, and so that efifb works out of the box when that happens.

      drivers/firmware: Make efi/esrt.c driver explicitly non-modular

      The Kconfig for this driver is currently hidden with:

      config EFI_ESRT
              bool

      ...meaning that it currently is not being built as a module by anyone.
      Lets remove the modular code that is essentially orphaned, so that
      when reading the driver there is no doubt it is builtin-only.

      Since module_init translates to device_initcall in the non-modular
      case, the init ordering remains unchanged with this commit.

      We leave some tags like MODULE_AUTHOR for documentation purposes.

      We don't replace module.h with init.h since the file already has that.

      sfc: fully reset if MC_REBOOT event received without warm_boot_count 
increment

      On EF10, MC_CMD_VPORT_RECONFIGURE can cause a CODE_MC_REBOOT event
      to be sent to a function without incrementing the (adapter-wide)
      warm_boot_count.  In this case, the reboot is not detected by the
      loop on efx_mcdi_poll_reboot(), so prepare for recovery from an MC
      reboot anyway.  When this codepath is run, the MC has always just
      rebooted, so this recovery is valid.

      The loop on efx_mcdi_poll_reboot() is still required for other MC
      reboot cases, so that actions in response to an MC reboot are
      performed, such as clearing locally calculated statistics.
      Siena NICs are unaffected by this change as the above scenario
      does not apply.

      ====================
      switchdev: push bridge ageing_time attribute down

      Push bridge-level attributes down to switchdev drivers.  This patchset
      adds the infrastructure and then pushes, as an example, ageing_time 
attribute
      down from bridge to switchdev (rocker) driver.  Add some range-checking
      for ageing_time.

      RTNETLINK answers: Numerical result out of range

      Up until now, switchdev attrs where port-level attrs, so the netdev used 
in
      switchdev_attr_set() would be a switch port or bond of switch ports.  With
      bridge-level attrs, the netdev passed to switchdev_attr_set() is the 
bridge
      netdev.  The same recusive algo is used to visit the leaves of the stacked
      drivers to set the attr, it's just in this case we start one layer higher 
in
      the stack.  One note is not all ports in the bridge may support setting a
      bridge-level attribute, so rather than failing the entire set, we'll skip 
over
      those ports returning -EOPNOTSUPP.

      v2->v3: Per Jiri review: push only ageing_time attr down at this time, and
      don't pass raw bridge IFLA_BR_* values; rather use new switchdev attr ID 
for
      ageing_time.

      bridge: push bridge setting ageing_time down to switchdev

      Use SWITCHDEV_F_SKIP_EOPNOTSUPP to skip over ports in bridge that don't
      support setting ageing_time (or setting bridge attrs in general).

      If push fails, don't update ageing_time in bridge and return err to user.

      If push succeeds, update ageing_time in bridge and run gc_timer now to
      recalabrate when to run gc_timer next, based on new ageing_time.

      switchdev: skip over ports returning -EOPNOTSUPP when recursing ports

      This allows us to recurse over all the ports, skipping over unsupporting

      tcp: change type of alive from int to bool

      The alive parameter of tcp_orphan_retries, indicates
      whether the connection is assumed alive or not.
      In the function and all places calling it is used as a boolean value.

      Therefore this changes the type of alive to bool in the function
      definition and all calling locations.

      Since tcp_orphan_tries is a tcp_timer.c local function no change in
      any other file or header is necessary.

      timers, kselftest: Add 'adjtick' test to validate adjtimex() tick 
adjustments

      Recently a kernel side NTP bug was fixed via the following commit:

        2619d7e9c92d ("time: Fix timekeeping_freqadjust()'s incorrect use of 
abs() instead of abs64()")

      When the bug was reported it was difficult to detect, except by
      tweaking the adjtimex tick value, and noticing how quickly the
      adjustment took:

        https://lkml.org/lkml/2015/9/1/488

      Thus this patch introduces a new test which manipulates the
      adjtimex tick value and validates that the results are what we
      expect.

      sched, tracing: Stop/start critical timings around the idle=poll idle loop

      When using idle=poll, the preemptoff tracer is always showing
      the idle task as the culprit for long latencies. That happens
      because critical timings are not stopped before idle loop. This
      patch stops critical timings before entering the idle loop,
      starting it again after the idle loop.

      This problem does not affect the irqsoff tracer because
      interruptions are enabled before entering the idle loop.

      drm/nouveau/bios: fix OF loading

      Currently OF bios load fails for a few reasons:
       - checksum failure
       - bios size too small
       - no PCIR header
       - bios length not a multiple of 4

      In this change, we resolve all of the above by ignoring any checksum
      failures (since OF VBIOS tends not to have a checksum), and faking the
      PCIR data when loading from OF.

      drm/nouveau/fbcon: take runpm reference when userspace has an open fd

      We need to do this in order to prevent accesses to the device while it's
      powered down.  Userspace may have an mmap of the fb, and there's no good
      way (that I know of) to prevent it from touching the device otherwise.

      This fixes some nasty races between runpm and plymouth on some systems,
      which result in the GPU getting very upset and hanging the boot.

      timers: Use __fls in apply_slack()

      In apply_slack(), find_last_bit() is applied to a bitmask consisting
      of precisely BITS_PER_LONG bits. Since mask is non-zero, we might as
      well eliminate the function call and use __fls() directly. On x86_64,
      this shaves 23 bytes of the only caller, mod_timer().

      This also gets rid of Coverity CID 1192106, but that is a false
      positive: Coverity is not aware that mask != 0 implies that
      find_last_bit will not return BITS_PER_LONG.

      tcp: fix RFS vs lockless listeners

      Before recent TCP listener patches, we were updating listener
      sk->sk_rxhash before the cloning of master socket.

      children sk_rxhash was therefore correct after the normal 3WHS.

      But with lockless listener, we no longer dirty/change listener sk_rxhash
      as it would be racy.

      We need to correctly update the child sk_rxhash, otherwise first data
      packet wont hit correct cpu if RFS is used.

      P2#: ifconfig eth0; which will call bnx2_get_stats64, it will

      bpf: fix cb access in socket filter programs

      eBPF socket filter programs may see junk in 'u32 cb[5]' area,
      since it could have been used by protocol layers earlier.

      For socket filter programs used in af_packet we need to clean
      20 bytes of skb->cb area if it could be used by the program.
      For programs attached to TCP/UDP sockets we need to save/restore
      these 20 bytes, since it's used by protocol layers.

      Remove SK_RUN_FILTER macro, since it's no longer used.

      Long term we may move this bpf cb area to per-cpu scratch, but that
      requires addition of new 'per-cpu load/store' instructions,
      so not suitable as a short term fix.

      genirq: Add flag to force mask in disable_irq[_nosync]()

      If an irq chip does not implement the irq_disable callback, then we
      use a lazy approach for disabling the interrupt. That means that the
      interrupt is marked disabled, but the interrupt line is not
      immediately masked in the interrupt chip. It only becomes masked if
      the interrupt is raised while it's marked disabled. We use this to avoid
      possibly expensive mask/unmask operations for common case operations.

      Unfortunately there are devices which do not allow the interrupt to be
      disabled easily at the device level. They are forced to use
      disable_irq_nosync(). This can result in taking each interrupt twice.

      Instead of enforcing the non lazy mode on all interrupts of a irq
      chip, provide a settings flag, which can be set by the driver for that
      particular interrupt line.

      efi: Use the generic efi.memmap instead of 'memmap'

      Guenter reports that commit:

        7bf793115dd9 ("efi, x86: Rearrange efi_mem_attributes()")

      breaks the IA64 compilation with the following error:

        drivers/built-in.o: In function `efi_mem_attributes': (.text+0xde962): 
undefined reference to `memmap'

      Instead of using the (rather poorly named) global variable
      'memmap' which doesn't exist on IA64, use efi.memmap which
      points to the 'memmap' object on x86 and arm64 and which is NULL
      for IA64.

      The fact that efi.memmap is NULL for IA64 is OK because IA64
      provides its own implementation of efi_mem_attributes().

      namei: results of d_is_negative() should be checked after dentry 
revalidation

      Leandro Awa writes:
       "After switching to version 4.1.6, our parallelized and distributed
        workflows now fail consistently with errors of the form:

        T34: ./regex.c:39:22: error: config.h: No such file or directory

        From our 'git bisect' testing, the following commit appears to be the
        possible cause of the behavior we've been seeing: commit 766c4cbfacd8"

      Al Viro says:
       "What happens is that 766c4cbfacd8 got the things subtly wrong.

        We used to treat d_is_negative() after lookup_fast() as "fall with
        ENOENT".  That was wrong - checking ->d_flags outside of ->d_seq
        protection is unreliable and failing with hard error on what should've
        fallen back to non-RCU pathname resolution is a bug.

        Unfortunately, we'd pulled the test too far up and ran afoul of
        another kind of staleness.  The dentry might have been absolutely
        stable from the RCU point of view (and we might be on UP, etc), but
        stale from the remote fs point of view.  If ->d_revalidate() returns
        "it's actually stale", dentry gets thrown away and the original code
        wouldn't even have looked at its ->d_flags.

        What we need is to check ->d_flags where 766c4cbfacd8 does (prior to
        ->d_seq validation) but only use the result in cases where we do not
        discard this dentry outright"

      arm/arm64: KVM: Only allow 64bit hosts to build VGICv3

      Hardware virtualisation of GICv3 is only supported by 64bit hosts for
      the moment. Some VGICv3 bits are missing from the 32bit side, and this
      patch allows to still be able to build 32bit hosts when CONFIG_ARM_GIC_V3
      is selected.

      To this end, we introduce a new option, CONFIG_KVM_ARM_VGIC_V3, that is
      only enabled on the 64bit side. The selection is done unconditionally
      because CONFIG_ARM_GIC_V3 is always enabled on arm64.

      ARM: add 32bit support to GICv3

      Implement the system and memory-mapped register accesses in
      asm/arch_gicv3.h for 32bit architectures.

      This patch is a straightforward translation of the arm64 header. 64bit
      accesses are done in two times and don't need atomicity: TYPER is
      read-only, and the upper-word of IROUTER is always zero on 32bit
      architectures.

      irqchip/gic-v3: Specialize readq and writeq accesses

      On 32bit platforms, we cannot assure that an I/O ldrd or strd will be
      done atomically. Besides, an hypervisor would be unable to emulate such
      accesses.
      In order to allow the AArch32 version of the driver to split them into
      two 32bit accesses while keeping the requirement for atomic writes, this
      patch specializes the IROUTER and TYPER accesses.
      Since the latter is an ID register, it won't need to be read atomically,
      but we still avoid future confusion by using gic_read_typer instead of a
      generic gic_readq.

      irqchip/gic-v3: Change unsigned types for AArch32 compatibility

      This patch does a few simple compatibility-related changes:
      - change the system register access prototypes to their actual size,
      - homogenise mpidr accesses with unsigned long,
      - force the 64bit register values to unsigned long long.

      Note: the list registers are 64bit on GICv3, but the AArch32 vGIC driver
      will need to split their values into two 32bit registers: LRn and LRCn.

      irqchip/gic-v2m: Add workaround for APM X-Gene GICv2m erratum

      APM X-Gene GICv2m implementation has an erratum where the
      MSI data needs to be the offset from the spi_start in order to
      trigger the correct MSI interrupt. This is different from the
      standard GICv2m implementation where the MSI data is the absolute
      value within the range from spi_start to (spi_start + num_spis)
      of each v2m frame.

      This patch reads MSI_IIDR register (present in all GICv2m
      implementations) to identify X-Gene GICv2m implementation and
      apply workaround to change the data portion of MSI vector.

      genirq: Allow migration of chained interrupts by installing default action

      When a CPU is offlined all interrupts that have an action are migrated to
      other still online CPUs. However, if the interrupt has chained handler
      installed this is not done. Chained handlers are used by GPIO drivers 
which
      support interrupts, for instance.

      When the affinity is not corrected properly we end up in situation where
      most interrupts are not arriving to the online CPUs anymore. For example 
on
      Intel Braswell system which has SD-card card detection signal connected to
      a GPIO the IO-APIC routing entries look like below after CPU1 is offlined:

        pin30, enabled , level, low , V(52), IRR(0), S(0), logical , D(03), M(1)
        pin31, enabled , level, low , V(42), IRR(0), S(0), logical , D(03), M(1)
        pin32, enabled , level, low , V(62), IRR(0), S(0), logical , D(03), M(1)
        pin5b, enabled , level, low , V(72), IRR(0), S(0), logical , D(03), M(1)

      The problem here is that the destination mask still contains both CPUs 
even
      if CPU1 is already offline. This means that the IO-APIC still routes
      interrupts to the other CPU as well.

      We solve the problem by providing a default action for chained interrupts.
      This action allows the migration code to correct affinity (as it finds
      desc->action != NULL).

      Also make the default action handler to emit a warning if for some reason 
a
      chained handler ends up calling it.

      In some cases, a new affinity is different, the old affinity need

IRQ_SET_MASK_OK_DONE,
      the old affinity can not be updated. Fix it by using irq_do_set_affinity.

      And migrating interrupts is a core code matter, so use the generic

      kernel/irq/migration.c.

      iommu/amd: Fix NULL pointer deref on device detach

      When a device group is detached from its domain, the iommu
      core code calls into the iommu driver to detach each device
      individually.

      Before this functionality went into the iommu core code, it
      was implemented in the drivers, also in the AMD IOMMU
      driver as the device alias handling code.

      This code is still present, as there might be aliases that
      don't exist as real PCI devices (and are therefore invisible
      to the iommu core code).

      Unfortunatly it might happen now, that a device is unbound
      multiple times from its domain, first by the alias handling
      code and then by the iommu core code (or vice verca).

      This ends up in the do_detach function which dereferences
      the dev_data->domain pointer. When the device is already
      detached, this pointer is NULL and we get a kernel oops.

      Removing the alias code completly is not an option, as that
      would also remove the code which handles invisible aliases.
      The code could be simplified, but this is too big of a
      change outside the merge window.

      For now, just check the dev_data->domain pointer in
      do_detach and bail out if it is NULL.

      However, some platforms do not stop the TWD block in low-power mode,
      and can thus use the TWD timer in one-shot mode, without setting up
      a broadcast device.

      Make the driver check for the "always-on" boolean property, and set
      the CLOCK_EVT_FEAT_C3STOP flag accordingly.

      genirq: Export handle_bad_irq

      A cleanup of the omap gpio driver introduced a use of the
      handle_bad_irq() function in a device driver that can be
      a loadable module.

      This broke the ARM allmodconfig build:

      ERROR: "handle_bad_irq" [drivers/gpio/gpio-omap.ko] undefined!

      This patch exports the handle_bad_irq symbol in order to
      allow the use in modules.

      Merge branch 'net-non-modular'

      Paul Gortmaker says:

      ====================
      make non-modular code explicitly non-modular

      [v2: drop m68k patches that Geert converted to modules; add one ARM
       driver patch ; update net-next baseline to today; switch to ARM
       for build testing.]

      In a previous merge window, we made changes to allow better
      delineation between modular and non-modular code in commit
      0fd972a7d91d6e15393c449492a04d94c0b89351 ("module: relocate module_init
      from init.h to module.h").  This allows us to now ensure module code
      looks modular and non-modular code does not accidentally look modular
      just to avoid suffering build breakage.

      Here we target code that is, by nature of their Makefile and/or
      Kconfig settings, only available to be built-in, but implicitly
      presenting itself as being possibly modular by way of using modular
      headers, macros, and functions.

      The goal here is to remove that illusion of modularity from these
      files, but in a way that leaves the actual runtime unchanged.
      In doing so, we remove code that has never been tested and adds
      no value to the tree.  And we continue the process of expecting a
      level of consistency between the Kconfig/Makefile of code and the
      code in use itself.

      Fortuntately the net subsystem has relatively few instances, given
      the overall amount of code and drivers it contains.  For comparison
      there are over 300 instances tree wide, resulting in a possible net
      removal of on the order of 5000 lines of unused code.

      Build tested on net-next from today, on ARM, since that is the arch
      where the one ethernet driver changed here is available.

      drivers/net/ethernet: make ti/cpsw-phy-sel.c explicitly non-modular

      The Kconfig currently controlling compilation of this code is:

      drivers/net/ethernet/ti/Kconfig:config TI_CPSW_PHY_SEL
      drivers/net/ethernet/ti/Kconfig:        bool "TI CPSW Switch Phy sel 
Support"

      ...meaning that it currently is not being built as a module by anyone.

      Lets remove the couple traces of modularity so that when reading the
      driver there is no doubt it is builtin-only.

      Since module_platform_driver() uses the same init level priority as
      builtin_platform_driver() the init ordering remains unchanged with
      this commit.

      Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

      We also delete the MODULE_LICENSE tag etc. since all that information
      was (or is now) contained at the top of the file in the comments.

      The Makefile currently controlling compilation of this code lists

      In preparation to handling system errors at the mlx5_core level, change 
the
      interface of cmd_work_handler to accept a 64 bit argument for the vector.

      This allows to encode a flag that signifies when the handler is called
      as a result of a driver logic that wishes to terminate commands that
      the hardware may not be able to terminate. Such command completions
      are detected at the handler and proper return status is encoded.

      To be able to terminate page handler commands, we make sure to set
      the corresponding bit in the bitmask.

      Intel Wired LAN Driver Updates 2015-10-08

      This series contains updates to i40e and i40evf only (again).

      Jesse fixes an issue where the driver was issuing a WARN_ON during ring
      size changes because the code was cloning the rx_ring struct but not
      zeroing out the pointers before allocating new memory, so simply zero
      out the pointers.  Also reduced the function call overhead by moving
      the interrupt enable function by moving it to the header file, which it
      in turn allows us to inline it.  Also does a thorough job of code
      cleanup to fix spaces after declarations, remove unnecessary braces
      and breaks, remove another __func__ use and general code tidiness.

      Mitch adds mover verbose error messages when the number of supported VFs
      is reported in driver init and it different from the number reported in
      config space.  Updated the VF driver to now detect a reset with the
      VF_ARQLEN register since the enable bit is cleared when the VF is reset
      and it stays cleared until the VF driver processes the reset and
      re-enables the admin queue which is more reliable than using the
      VFGEN_RSTAT as previously.

      Neerav adds parsing for CEE DCBx TLVs from the LLDP MIB since there is
      a need to get the CEE DesiredCfg Tx by firmware and DCB configuration
      Rx from peer for debug and other application purposes.

      Carolyn fixes a problem where the PF's Flow Director filter table would
      have an entry that the hardware was unable to add, when this occurs an
      invalid entry gets replayed and a valid one is lost.

      Matt fixes an issue where multiple link up messages can be logged
      resulting from admin queue link status timing when link properties are
      changed.

      Shannon adds the ability to control the period link polling through
      ethtool to be able to switch it off and on for debugging link issues.

      Serey explicitly assigns the enum index for each VSI type so that the PF
      and VF always reference to the same VSI type event if the enum lists
      are different.

      dm cache: fix NULL pointer when switching from cleaner policy

      The cleaner policy doesn't make use of the per cache block hint space in
      the metadata (unlike the other policies).  When switching from the
      cleaner policy to mq or smq a NULL pointer crash (in dm_tm_new_block)
      was observed.  The crash was caused by bugs in dm-cache-metadata.c
      when trying to skip creation of the hint btree.

      The minimal fix is to change hint size for the cleaner policy to 4 bytes
      (only hint size supported).

      ARC is the only arch with unsigned long type (vs. struct page *).
      Historically this was done to avoid the page_address() calls in various
      arch hooks which need to get the virtual/logical address of the table.

      Some arches alternately define it as pte_t *, and is as efficient as
      unsigned long (generated code doesn't change)

      ath: fix DFS timestamp wraparound reset condition

      The DFS pattern detector ought to reset the
      detector lines when a pulse is added with
      lower time stamp than the previous (which
      indicates a TSF restart).

      This did not work so far and is fixed with
      this patch.

      The modification does not change detection
      performance within the driver, since it
      only ensures early reset (which is later
      performed by the PRI detectors anyway).
      It is relevant for synthetic tests and
      statistical evaluations, where millions
      of pulse patterns are processed and an
      early reset helps reducing load.

      ath10k: optimize ce_lock on post rx buffer processing

      After processing received packets from copy engine, host will allocate
      new buffer and queue them back to copy engine ring for further
      packet reception. On post rx processing path, skb allocation and
      dma mapping are unnecessarily handled within ce_lock. This is affecting
      peak throughput and also causing more CPU consumption. Optimize this
      by acquiring ce_lock only when accessing copy engine ring and moving
      skb allocation out of ce_lock.

      In AP148 platform with QCA99x0 in conducted environment, UDP uplink peak
      throughput is improved from ~1320 Mbps to ~1450 Mbps and TCP uplink peak
      throughput is increased from ~1240 Mbps (70% host CPU load) to ~1300 Mbps
      (71% CPU load). Similarly ~40Mbps improvement is observed in downlink
      path.

      It is noticed that pci wakeup time is exceeding current timeout (10ms)
      randomly which is tested on QCA988x. So, the wake up time is increased
      to 30 ms and added debug prints to log total timeout.

      x86/entry: Split and inline syscall_return_slowpath()

      GCC is unable to properly optimize functions that have a very
      short likely case and a longer and register-heavier cold part --
      it fails to sink all of the register saving and stack frame
      setup code into the unlikely part.

      Help it out with syscall_return_slowpath() by splitting it into
      two parts and inline the hot part.

      Saves 6 cycles for compat syscalls.

      x86/entry: Micro-optimize compat fast syscall arg fetch

      We're following a 32-bit pointer, and the uaccess code isn't
      smart enough to figure out that the access_ok() check isn't
      needed.

      This saves about three cycles on a cache-hot fast syscall.

      On systems that support fast syscalls, we only really care about
      the performance of the fast syscall path.  Forcibly inline it
      and add a likely annotation.

      This saves 4-6 cycles.

      We could reinstate something like it as an optimization, which

      x86/entry/compat: Implement opportunistic SYSRETL for compat syscalls

      If CS, SS and IP are as expected and FLAGS is compatible with
      SYSRETL, then return from fast compat syscalls (both SYSCALL and
      SYSENTER) using SYSRETL.

      Unlike native 64-bit opportunistic SYSRET, this is not invisible
      to user code: RCX and R8-R15 end up in a different state than
      shown saved in pt_regs.  To compensate, we only do this when
      returning to the vDSO fast syscall return path.  This won't
      interfere with syscall restart, as we won't use SYSRETL when
      returning to the INT80 restart instruction.

      x86/syscalls: Give sys_call_ptr_t a useful type

      Syscalls are asmlinkage functions (on 32-bit kernels), take six
      args of type unsigned long, and return long.  Note that uml
      could probably be slightly cleaned up on top of this patch.

      x86/entry/64/compat: Set up full pt_regs for all compat syscalls

      This is conceptually simpler.  More importantly, it eliminates
      the PTREGSCALL and execve stubs, which were not compatible with
      the C ABI.  This means that C code can call through the compat
      syscall table.

      The execve stubs are a bit subtle.  They did two things: they
      cleared some registers and they forced slow-path return.
      Neither is necessary any more: elf_common_init clears the extra
      registers and start_thread calls force_iret().

      x86/vdso/32: Save extra registers in the INT80 vsyscall path

      The goal is to integrate the SYSENTER and SYSCALL32 entry paths
      with the INT80 path.  SYSENTER clobbers ESP and EIP.  SYSCALL32
      clobbers ECX (and, invisibly, R11).  SYSRETL (long mode to
      compat mode) clobbers ECX and, invisibly, R11.  SYSEXIT (which
      we only need for native 32-bit) clobbers ECX and EDX.

      This means that we'll need to provide ESP to the kernel in a
      register (I chose ECX, since it's only needed for SYSENTER) and
      we need to provide the args that normally live in ECX and EDX in
      memory.

      The epilogue needs to restore ECX and EDX, since user code
      relies on regs being preserved.

      We don't need to do anything special about EIP, since the kernel
      already knows where we are.  The kernel will eventually need to
      know where int $0x80 lands, so add a vdso_image entry for it.

      The only user-visible effect of this code is that ptrace-induced
      changes to ECX and EDX during fast syscalls will be lost.  This
      is already the case for the SYSENTER path.

      x86/vdso: Replace hex int80 CFI annotations with GAS directives

      Maintaining the current CFI annotations written in R'lyehian is
      difficult for most of us.  Translate them to something a little
      closer to English.

      This will remove the CFI data for kernels built with extremely
      old versions of binutils.  I think this is a fair tradeoff for
      the ability for mortals to edit the asm.

      drm: Fix locking for sysfs dpms file

      With atomic drivers we need to make sure that (at least in general)
      property reads hold the right locks. But the legacy dpms property is
      special and can be read locklessly. Since userspace loves to just
      randomly look at that all the time (like with "status") do that.

      To make it clear that we play tricks use the READ_ONCE compiler
      barrier (and also for paranoia).

      Note that there's not really anything bad going on since even with the
      new atomic paths we eventually end up not chasing any pointers (and
      hence possibly freed memory and other fun stuff). The locking WARNING
      has been added in

      i40evf: detect reset more reliably

      Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught
      with peril. It's entirely too easy to miss a reset because none of the
      bits are sticky. By the time the VF driver reads the register, the reset
      may have been processed and cleaned up by the PF driver, leaving the
      register in the same state that it was before the reset.

      Instead, detect a reset with the VF_ARQLEN register. When the VF is
      reset, the enable bit in this register is cleared, and it stays cleared
      until the VF driver processes the reset and re-enables the admin queue.

      Because we now deal with multiple registers in the reset and watchdog
      tasks, rename the rstat_val variable to reg_val.

      i40e/i40evf: Explicitly assign enum index for VSI type

      Ran into an issue where PF's VSI type list was different from VF's,
      which was resulted in different enum index. The VSI type list can
      be different depending on what build flag is used for PF and VF.

      The change is to explicitly assign enum index for each VSI type
      so that PF and VF always reference to the same VSI type event if the
      enum lists are different.

      but can be turned off with
        ethtool --set-priv-flags p261p1 LinkPolling off
      and later turned back on with
        ethtool --set-priv-flags p261p1 LinkPolling on

      To check the current status, use
        ethtool --show-priv-flags p261p1

      crash in md-raid1 and md-raid10 due to incorrect list manipulation

      The commit 55ce74d4bfe1b9444436264c637f39a152d1e5ac (md/raid1: ensure
      device failure recorded before write request returns) is causing crash in
      the LVM2 testsuite test shell/lvchange-raid.sh. For me the crash is 100%
      reproducible.

      The reason for the crash is that the newly added code in raid1d moves the
      list from conf->bio_end_io_list to tmp, then tests if tmp is non-empty and
      then incorrectly pops the bio from conf->bio_end_io_list (which is empty
      because the list was alrady moved).

      Raid-10 has a similar bug.

      powerpc/powernv: Panic on unhandled Machine Check

      All unrecovered machine check errors on PowerNV should cause an
      immediate panic. There are 2 reasons that this is the right policy:
      it's not safe to continue, and we're already trying to reboot.

      Firstly, if we go through the recovery process and do not successfully
      recover, we can't be sure about the state of the machine, and it is
      not safe to recover and proceed.

      Linux knows about the following sources of Machine Check Errors:
      - Uncorrectable Errors (UE)
      - Effective - Real Address Translation (ERAT)
      - Segment Lookaside Buffer (SLB)
      - Translation Lookaside Buffer (TLB)
      - Unknown/Unrecognised

      In the SLB, TLB and ERAT cases, we can further categorise these as
      parity errors, multihit errors or unknown/unrecognised.

      We can handle SLB errors by flushing and reloading the SLB. We can
      handle TLB and ERAT multihit errors by flushing the TLB. (It appears
      we may not handle TLB and ERAT parity errors: I will investigate
      further and send a followup patch if appropriate.)

      This leaves us with uncorrectable errors. Uncorrectable errors are
      usually the result of ECC memory detecting an error that it cannot
      correct, but they also crop up in the context of PCI cards failing
      during DMA writes, and during CAPI error events.

      There are several types of UE, and there are 3 places a UE can occur:
      Skiboot, the kernel, and userspace. For Skiboot errors, we have the
      facility to make some recoverable. For userspace, we can simply kill
      (SIGBUS) the affected process. We have no meaningful way to deal with
      UEs in kernel space or in unrecoverable sections of Skiboot.

      Currently, these unrecovered UEs fall through to
      machine_check_expection() in traps.c, which calls die(), which OOPSes
      and sends SIGBUS to the process. This sometimes allows us to stumble
      onwards. For example we've seen UEs kill the kernel eehd and
      khugepaged. However, the process killed could have held a lock, or it
      could have been a more important process, etc: we can no longer make
      any assertions about the state of the machine. Similarly if we see a
      UE in skiboot (and again we've seen this happen), we're not in a
      position where we can make any assertions about the state of the
      machine.

      Likewise, for unknown or unrecognised errors, we're not able to say
      anything about the state of the machine.

      Therefore, if we have an unrecovered MCE, the most appropriate thing
      to do is to panic.

      The second reason is that since e784b6499d9c ("powerpc/powernv: Invoke
      opal_cec_reboot2() on unrecoverable machine check errors."), we
      attempt a special OPAL reboot on an unhandled MCE. This is so the
      hardware can record error data for later debugging.

      The comments in that commit assert that we are heading down the panic
      path anyway. At the moment this is not always true. With UEs in kernel
      space, for instance, they are marked as recoverable by the hardware,
      so if the attempt to reboot failed (e.g. old Skiboot), we wouldn't
      panic() but would simply die() and OOPS. It doesn't make sense to be
      staggering on if we've just tried to reboot: we should panic().

      Explicitly panic() on unrecovered MCEs on PowerNV.
      Update the comments appropriately.

      This fixes some hangs following EEH events on cxlflash setups.

      powerpc: Fix checkstop in native_hpte_clear() with lockdep

      native_hpte_clear() is called in real mode from two places:
      - Early in boot during htab initialisation if firmware assisted dump is
        active.
      - Late in the kexec path.

      In both contexts there is no need to disable interrupts are they are
      already disabled. Furthermore, locking around the tlbie() is only required
      for pre POWER5 hardware.

      On POWER5 or newer hardware concurrent tlbie()s work as expected and on 
pre
      POWER5 hardware concurrent tlbie()s could result in deadlock. This code
      would only be executed at crashdump time, during which all bets are off,
      concurrent tlbie()s are unlikely and taking locks is unsafe therefore the
      best course of action is to simply do nothing. Concurrent tlbie()s are not
      possible in the first case as secondary CPUs have not come up yet.

      not in nbd context anymore. This was not observed or reproducable yet.

      This patch adds locking to critical use of task_recv and task_send to
      avoid killing tasks that already left the NBD thread functions. This
      lock is only acquired if a timeout occures or the nbd device
      starts/stops.

      The Atmel sdhci device needs a new quirk. sdhci_set_clock set the Clock
      Control Register to 0 before computing the new value and writing it.
      It disables the internal clock which causes a reset mecanism. If we
      write the new value before this reset mecanism is done, it will prevent
      the stabilisation of the internal clock, so a delay is needed. This
      delay is about 2-3 cycles of the base clock. To be safe, a 1 ms delay is
      used.

      arm64: Mark kernel page ranges contiguous

      With 64k pages, the next larger segment size is 512M. The linux
      kernel also uses different protection flags to cover its code and data.
      Because of this requirement, the vast majority of the kernel code and
      data structures end up being mapped with 64k pages instead of the larger
      pages common with a 4k page kernel.

      Recent ARM processors support a contiguous bit in the
      page tables which allows the a TLB to cover a range larger than a
      single PTE if that range is mapped into physically contiguous
      ram.

      So, for the kernel its a good idea to set this flag. Some basic
      micro benchmarks show it can significantly reduce the number of
      L1 dTLB refills.

      Add boot option to enable/disable CONT marking, as well as fix a
      bug found by Steve Capper.

      Bluetooth: Fix basic debugfs entries for unconfigured controllers

      When the controller is unconfigured (for example it does not have a
      valid Bluetooth address), then the basic debugfs entries for dut_mode
      and vendor_diag are not creates. Ensure they are created in __hci_init
      and also __hci_unconf_init functions. One of them is called during setup
      stage of a new controller.

      BPF/random32 updates

      BPF update to split the prandom state apart, and to move the
      *once helpers to the core. For details, please see individual
      patches. Given the changes and since it's in the tree for
      quite some time, net-next is a better choice in our opinion.

      v1 -> v2:
       - Make DO_ONCE() type-safe, remove the kvec helper. Credits
         go to Alexei Starovoitov for the __VA_ARGS__ hint, thanks!
       - Add a comment to the DO_ONCE() helper as suggested by Alexei.
       - Rework prandom_init_once() helper to the new API.
       - Keep Alexei's Acked-by on the last patch.

      bpf: split state from prandom_u32() and consolidate {c, e}BPF prngs

      While recently arguing on a seccomp discussion that raw prandom_u32()
      access shouldn't be exposed to unpriviledged user space, I forgot the
      fact that SKF_AD_RANDOM extension actually already does it for some time
      in cBPF via commit 4cd3675ebf74 ("filter: added BPF random opcode").

      Since prandom_u32() is being used in a lot of critical networking code,
      lets be more conservative and split their states. Furthermore, consolidate
      eBPF and cBPF prandom handlers to use the new internal PRNG. For eBPF,
      bpf_get_prandom_u32() was only accessible for priviledged users, but
      should that change one day, we also don't want to leak raw sequences
      through things like eBPF maps.

      One thought was also to have own per bpf_prog states, but due to ABI
      reasons this is not easily possible, i.e. the program code currently
      cannot access bpf_prog itself, and copying the rnd_state to/from the
      stack scratch space whenever a program uses the prng seems not really
      worth the trouble and seems too hacky. If needed, taus113 could in such
      cases be implemented within eBPF using a map entry to keep the state
      space, or get_random_bytes() could become a second helper in cases where
      performance would not be critical.

      Both sides can trigger a one-time late init via prandom_init_once() on
      the shared state. Performance-wise, there should even be a tiny gain
      as bpf_user_rnd_u32() saves one function call. The PRNG needs to live
      inside the BPF core since kernels could have a NET-less config as well.

      random32: add prandom_init_once helper for own rngs

      Add a prandom_init_once() facility that works on the rnd_state, so that
      users that are keeping their own state independent from prandom_u32() can
      initialize their taus113 per cpu states.

      The motivation here is similar to net_get_random_once(): initialize the
      state as late as possible in the hope that enough entropy has been
      collected for the seeding. prandom_init_once() makes use of the recently
      introduced prandom_seed_full_state() helper and is generic enough so that
      it could also be used on fast-paths due to the DO_ONCE().

      once: make helper generic for calling functions once

      Make the get_random_once() helper generic enough, so that functions
      in general would only be called once, where one user of this is then
      net_get_random_once().

      The only implementation specific call is to get_random_bytes(), all
      the rest of this *_once() facility would be duplicated among different
      subsystems otherwise. The new DO_ONCE() helper will be used by prandom()
      later on, but might also be useful for other scenarios/subsystems as
      well where a one-time initialization in often-called, possibly fast
      path code could occur.

      net: Do not drop to make_route if oif is l3mdev

      Commit deaa0a6a930 ("net: Lookup actual route when oif is VRF device")
      exposed a bug in __ip_route_output_key_hash for VRF devices: on FIB lookup
      failure if the oif is specified the current logic drops to make_route on
      the assumption that the route tables are wrong. For VRF/L3 master devices
      this leads to wrong dst entries and route lookups. For example:
          $ ip route ls table vrf-red

      Add support for Broadcom's iProc MDIO and Cygnus Ethernet PHY

      This patchset adds support for the iProc MDIO interface and the
      Broadcom Cygnus SoC's internal Ethernet PHY.

      The internal Ethernet PHY(s) in the Cygnus SoC's are accessed
      via the MDIO interface found in most of the iProc based chips.

      The patch also consolidates the common API's used by the
      Broadcom phys to a common library. Existing Broadcom phy
      drivers have been modified to use the common library API's.

      This patch series is based on Linux v4.3-rc1 and is avaliable in:
      https://github.com/Broadcom/cygnus-linux/tree/cygnus-net-phy-mdio-v3

      The Ethernet driver for the iProc family will be submitted soon,
      as will the device tree configurations for the different iProc
      family SoCs.

      Changes from v2:
      - Modified drivers/net/phy/Kconfig to modify the BCM_CYGNUS_PHY
        driver to 'depends on MDIO_BCM_IPROC' instead of 'select'.
      - Added github branch to the cover letter

      Changes from v1:
      - Updated device tree documentation for the iProc MDIO driver
        based on Florian's feedback.
      - Moved the core register defines from the Cygnus PHY driver to
        'include/linux/brcmphy.h' based on Florian's feedback.
      - Created a new patch/commit to modify the bcm7xxx phy driver
        to use the new core register defines.
      - Modified the Kconfig entry for the Broadcom PHY library to
        'tristate' instead of 'bool'

      This driver supports the following Broadcom Cygnus SoCs:
       - BCM583XX (BCM58300, BCM58302, BCM58303, BCM58305)
       - BCM113XX (BCM11300, BCM11320, BCM11350, BCM11360)

      The PHY's on these SoC's require some workarounds for
      stable operation, both during configuration time and
      during suspend/resume. This driver handles the
      application of the workarounds.

      The MDIO bus is accessed using a combination of command and data
      registers. This MDIO driver provides access to the Etherent GPHY's
      connected to the MDIO bus.

      RDS: connection scalability and performance improvements

      [v4]
      Re-sending the same patches from v3 again since my repost of
      patch 05/14 from v3 was whitespace damaged.

      [v3]
      Updated patch "[PATCH v2 05/14] RDS: defer the over_batch work to
      send worker" as per David Miller's comment [4] to avoid the magic
      value usage. Patch now makes use of already available but unused
      send_batch_count module parameter. Rest of the patches are same as
      earlier version v2 [3]

      [v2]:
      Dropped "[PATCH 05/15] RDS: increase size of hash-table to 8K" from
      earlier version [1]. I plan to address the hash table scalability using
      re-sizable hash tables as suggested by David Laight and David Miller [2]

      This series addresses RDS connection bottlenecks on massive workloads and
      improve the RDMA performance almost by 3X. RDS TCP also gets a small gain
      of about 12%.

      RDS is being used in massive systems with high scalability where several
      hundred thousand end points and tens of thousands of local processes
      are operating in tens of thousand sockets. Being RC(reliable connection),
      socket bind and release happens very often and any inefficiencies in
      bind hash look ups hurts the overall system performance. RDS bin 
hash-table
      uses global spin-lock which is the biggest bottleneck. To make matter 
worst,
      it uses rcu inside global lock for hash buckets.
      This is being addressed by simply using per bucket rw lock which makes the
      locking simple and very efficient. The hash table size is still an issue 
and
      I plan to address it by using re-sizable hash tables as suggested on the 
list.

      For RDS RDMA improvement, the completion handling is revamped so that we
      can do batch completions. Both send and receive completion handlers are
      split logically to achieve the same. RDS 8K messages being one of the
      key usecase, mr pool is adapted to have the 8K mrs along with default 1M
      mrs. And while doing this, few fixes and couple of bottlenecks seen with
      rds_sendmsg() are addressed.

      Series applies against 4.3-rc1 as well net-next. Its tested on Oracle
      hardware with IB fabric for both bcopy as well as RDMA mode. RDS TCP is
      tested with iXGB NIC. Like last time, iWARP transport is untested with
      these changes. The patchset is also available at below git repo:

      git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux.git 
net/rds/4.3-v3

      As a side note, the IB HCA driver I used for testing misses at least 3
      important patches in upstream to see the full blown IB performance and
      am hoping to get that in mainline with help of them.

      Eric W. Biederman says:

      ====================
      net: Pass net through the output path v2

      This is the next installment of my work to pass struct net through the
      output path so the code does not need to guess how to figure out which
      network namespace it is in, and ultimately routes can have output
      devices in another network namespace.

      The first patch in this series is a fix for a bug that came in when sk
      was passed through the functions in the output path, and as such is
      probably a candidate for net.  At the same time my later patches depend
      on it so sending the fix separately would be confusing.

      The second patch in this series is another fix that for an issue that
      came in when sk was passed through the output path.  I don't think it
      needs a backport as I don't think anyone uses the path where the code
      was incorrect.

      The rest of the patchset focuses on the path from xxx_local_out to
      dst_output and in the end succeeds in passing sock_net(sk) from the
      socket a packet locally originates on to the dst->output function.

      Given the size reduction in the code I think this counts as a cleanup as
      much as feature work.

      There remain a number of helper functions (like ip option processing) to
      take care of before the network stack can support destination devices in
      other network namespaces but with this set of changes the backbone of
      the work is done.

      ipv4: Fix ip_queue_xmit to pass sk into ip_local_out_sk

      After a packet has been encapsulated by a tunnel we should use the
      tunnel sockets local multicast loopback flag to control if the
      encapsulated packet should be locally loopback back.

      Pass sk into ip_local_out_sk so that in the rare case we are dealing
      with a tunneled packet whose tunnel destination address is a multicast
      address the kernel properly decides to loopback this packet.

      In practice I don't think this matters as ip_queue_xmit is used by
      tcp, l2tp and sctp none of which I am aware of uses ip level
      multicasting as they are all point to point communications protocols.
      Let's fix this before someone uses ip_queue_xmit for a tunnel protocol
      that does use multicast.

      Intel Wired LAN Driver Updates 2015-10-07

      This series contains updates to i40e and i40evf only.

      Paul updates i40e to simply increase the amount of time we wait for a
      reset to complete since we have seen in some rare occasions the reset
      can take longer to complete.

      Shannon updates the driver to turn on Wake-on-LAN by default if it is
      enabled in the hardware config to begin with, rather than always disable
      it and wait for the user to expressly turn it on.  Added new device id's
      and support for future devices.  Fixed a possible type compare problem
      between a size and possible negative number.  Also fixed a shift value
      that was wrong, which ended up with a bad bitmask.  Did general house
      cleaning of the driver to cleanup several low lying fruit in the
      driver.  Fixed an issue where new unicast address's would be added to
      the VSI list and then immediately removed and would never actually
      make it down to the hardware.  Resolved the issue by removing the
      separation from unicast and multicast in the search for filters to be
      deleted.

      Mitch fixes an issue where the hardware would continue to access the
      memory formerly used by the rings for a VF which have been removed,
      causing memory corruption or DMAR errors.  To relieve this condition,
      explicitly stop all rings associated with each VF before releasing its
      resources.  Also fixed a panic if the driver is unable to enable MSI-X
      or its unable to acquire enough vectors, so propagate interrupt
      allocation failure information to the calling function.  Cleaned up
      opcode that is not required.

      Carolyn extends the size of the test available for the interrupt names
      so that all the descriptive data available for the Flow Director
      interrupts is not truncated.

      Catherine fixes an issue where there was a possibility of speed getting
      set to 0 if advertised is set to 0 (which is the case when autoneg is
      disabled).

      Jesse fixes the checksum on big endian machines, so added code to swap
      it correctly.  Also fixed a bug in the return from get_link_status()
      where only true or false was being returned, but false could mean
      multiple things.  So allow the caller to get all the return values
      in the call chain bubbled back to the source so that the reason for
      the failure does not get lost.

      Anjali adds statistics to keep track of how many times we ask the stack
      to linearize the SKB because the hardware cannot handle SKBs with more
      than 8 frags per segment/single packet.

      mmc: host: omap_hsmmc: Fix MMC for omap3 legacy booting

      Starting with commit 7d607f917008 ("mmc: host: omap_hsmmc: use
      devm_regulator_get_optional() for vmmc") MMC on omap3 stopped working
      for legacy booting.

      This is because legacy booting sets up some of the resource in the
      platform init code, and for optional regulators always seem to
      return -EPROBE_DEFER for the legacy booting.

      Let's fix the issue by checking for device tree based booting for
      now. Then when omap3 boots in device tree only mode, this patch
      can be just reverted.

      rcu: Better hotplug handling for synchronize_sched_expedited()

      Earlier versions of synchronize_sched_expedited() can prematurely end
      grace periods due to the fact that a CPU marked as cpu_is_offline()
      can still be using RCU read-side critical sections during the time that
      CPU makes its last pass through the scheduler and into the idle loop
      and during the time that a given CPU is in the process of coming online.
      This commit therefore eliminates this window by adding additional
      interaction with the CPU-hotplug operations.

      i40evf: propagate interrupt allocation failure

      Lower level functions are properly reporting errors, and higher-level
      functions are correctly responding to errors, but the errors aren't
      actually getting through. Typically, the middle-manager function seems
      to want to shield its boss from any bad news.

      This change fixes a panic if the driver is unable to enable MSI-X or is
      unable to acquire enough vectors.

      i40e: Additional checks for CEE APP priority validity

      The firmware has added additional status information to allow software
      to determine if the APP priority for FCoE/iSCSI/FIP is valid or not in
      CEE DCBX mode.

      This patch adds to support those additional checks and will only add

      i40e/i40evf: fix unicast mac address add

      When using something like "ip maddr add ..." to add another unicast mac
      address to the netdev, the mac address comes into the set_rx_mode handler
      in the multicast list whether it is a unicast or multicast address.
      This was confusing the code when it was trying to search for addresses
      that needed to be deleted from the VSI, because it was looking for the
      VSI unicast address in the netdev unicast list.  The result was that a
      new unicast address would get added to the VSI list and then immediately
      removed, and would never actually make it down into the hardware.

      This patch removes the separation from unicast and multicast in the search
      for filters to be deleted.  It also simplifies the logic a little with a
      jump to the bottom of the loop when an address is found.  Now it doesn't
      matter which netdev list the address is hiding in, we'll check them all.

      i40e: fix bug in return from get_link_status and avoid spurious link 
messages

      Previously, the driver could call this function and have only true/false
      returned, but false could mean multiple things like failure to read
      or link was down. This change allows the caller to get all return values
      in the call chain bubbled back to the source, which keeps information 
about
      failures from being lost.

      Also, in some unlikely scenarios, the firmware can become slow to respond
      to admin queue (AQ) queries for link state.  Should the AQ time out,
      the driver can detect the state and avoid a link change when there
      may have been none.

      Explicitly stop the rings belonging to each VF when disabling SR-IOV.
      Even though the VFs were gone, and the associated VSIs were removed, the
      rings were not stopped, and in some circumstances the hardware would
      continue to access the memory formerly used by the rings, causing memory
      corruption or DMAR errors, both of which would lead to general malaise
      of the kernel.

      To relieve this condition, explicitly stop all the rings associated with
      each VF before releasing its resources.

      swiotlb: Enable it under x86 PAE

      Most distributions end up enabling SWIOTLB already with 32-bit
      kernels due to the combination of CONFIG_HYPERVISOR_GUEST|CONFIG_XEN=y
      as those end up requiring the SWIOTLB.

      However for those that are not interested in virtualization and
      run in 32-bit they will discover that: "32-bit PAE 4.2.0 kernel
      (no IOMMU code) would hang when writing to my USB disk. The kernel
      spews million(-ish messages per sec) to syslog, effectively
      "hanging" userspace with my kernel.

      Enabling it makes the problem go away.

      "config: Enable NEED_DMA_MAP_STATE by default when SWIOTLB is selected"
      we also have the important part of the SG macros enabled to make this

      but they're all useful if you do happen to have an affected device.

      3w-9xxx: don't unmap bounce buffered commands

      3w controller don't dma map small single SGL entry commands but instead
      bounce buffer them.  Add a helper to identify these commands and don't
      call scsi_dma_unmap for them.

      Based on an earlier patch from James Bottomley.

      drm/amdgpu: fix 32-bit compiler warning

      The new amdgpu driver passes a user space pointer in a 64-bit structure
      member, which is the correct way to do it, but it attempts to
      directly cast it to a __user pointer in the kernel, which causes
      a warning in three places:

      drm/amd/amdgpu/amdgpu_cs.c: In function 'amdgpu_cs_parser_init':
      drm/amd/amdgpu/amdgpu_cs.c:180:21: warning: cast to pointer from integer 
of different size [-Wint-to-pointer-cast]
        chunk_array_user = (uint64_t __user *)(cs->in.chunks);

      This changes all three to add an intermediate cast to 'unsigned long'
      as other drivers do. This avoids the warning and works correctly on
      both 32-bit and 64-bit architectures.

      perf tools: Fix build break on powerpc due to sample_reg_masks

      perf_regs.c does not get built on Powerpc as CONFIG_PERF_REGS is false.
      So the weak definition for 'sample_regs_masks' doesn't get picked up.

      Adding perf_regs.o to util/Build unconditionally, exposes a redefinition
      error for 'perf_reg_value()' function (due to the static inline version
      in util/perf_regs.h). So use #ifdef HAVE_PERF_REGS_SUPPORT' around that
      function.

      arm64: hw_breakpoint: use target state to determine ABI behaviour

      The arm64 hw_breakpoint interface is slightly less flexible than its
      32-bit counterpart, thanks to some changes in the architecture rendering
      unaligned watchpoint addresses obselete for AArch64.

      However, in a multi-arch environment (i.e. debugging a 32-bit target
      with a 64-bit GDB under a 64-bit kernel), we need to provide a feature
      compatible interface to GDB in order for debugging to function correctly.

      This patch adds a new helper, is_compat_bp,  to our hw_breakpoint
      implementation which changes the interface behaviour based on the
      architecture of the debug target as opposed to the debugger itself.
      This allows debugged to function as expected for multi-arch
      configurations without relying on deprecated architectural behaviours
      when debugging native applications.

      OVS conntrack fixes for net

      The userspace side of the Open vSwitch conntrack changes is currently
      undergoing review, which has highlighted some minor bugs in the existing
      conntrack implementation in the kernel, as well as pointing out some
      future-proofing that can be done on the interface to reduce the need for
      additional compatibility code in future.

      The biggest changes here are to the userspace API for the ct_state match
      field and the CT action. This series proposes to firstly extend the 
ct_state
      match field to 32 bits, ensuring to reject any currently unsupported bits.
      Secondly, rather than representing CT action flags within a 32-bit field,
      simply use a netlink attribute as presence of the single flag that is
      defined today. This also serves to reject unsupported ct action flag bits.

      v4: Use 12-character abbreviated hashes in commit messages.
      v3: Fully acked.
      v2: Address minor style feedback, add acks.
      v1: Initial post.

      openvswitch: Change CT_ATTR_FLAGS to CT_ATTR_COMMIT

      Previously, the CT_ATTR_FLAGS attribute, when nested under the
      OVS_ACTION_ATTR_CT, encoded a 32-bit bitmask of flags that modify the
      semantics of the ct action. It's more extensible to just represent each
      flag as a nested attribute, and this requires no additional error
      checking to reject flags that aren't currently supported.

      openvswitch: Extend ct_state match field to 32 bits

      The ct_state field was initially added as an 8-bit field, however six of
      the bits are already being used and use cases are already starting to
      appear that may push the limits of this field. This patch extends the
      field to 32 bits while retaining the internal representation of 8 bits.
      This should cover forward compatibility of the ABI for the foreseeable
      future.

      This patch also reorders the OVS_CS_F_* bits to be sequential.

      openvswitch: Reject ct_state unsupported bits

      Previously, if userspace specified ct_state bits in the flow key which
      are currently undefined (and therefore unsupported), then they would be
      ignored. This could cause unexpected behaviour in future if userspace is
      extended to support additional bits but attempts to communicate with the
      current version of the kernel. This patch rectifies the situation by
      rejecting such ct_state bits.

      openvswitch: Fix skb leak in ovs_fragment()

      If ovs_fragment() was unable to fragment the skb due to an L2 header
      that exceeds the supported length, skbs would be leaked. Fix the bug.

      net: dsa: complete and fix the dsa unbinding

      In order to cleanly unbind the dsa core, either as a module removal,
      or a platform device unbind, switch the allocation the their devm_
      counterparts and complete the destroy functions.

      First, the missing kfree were added, the remove function were
      completed then kfree were removed in favor to devm_ calls.

      The last patch is an way to cleanly exit the probe when no
      switch is found in the discover process.

      The patches are based on the current net.

      s390/qeth: optimize MAC handling in rx_mode callback

      In layer2 mode of the qeth driver, MAC address lists
      from struct net_device require mapping to the OSA-card.
      The existing implementation is inefficient for lists with
      more than several MAC addresses, since for every
      ndo_set_rx_mode callback it removes all MAC addresses first,
      and then registers the current MAC address list.
      This patch changes implementation of ndo_set_rx_mode callback
      in qeth, only performing hardware registration/removal for
      new/deleted addresses. To shorten lookup of MAC addresses
      registered addresses are kept in a hashtable instead of a
      linear list.

      needs the FLOWI_FLAG_SKIP_NH_OIF flag set. This latest commit causes
      the oif to be considered in lookups which is known to break vti. This

      net: Fix vti use case with oif in dst lookups for IPv6

      It occurred to me yesterday that 741a11d9e4103 ("net: ipv6: Add
      RT6_LOOKUP_F_IFACE flag if oif is set") means that xfrm6_dst_lookup
      needs the FLOWI_FLAG_SKIP_NH_OIF flag set. This latest commit causes
      the oif to be considered in lookups which is known to break vti. This
      explains why 58189ca7b274 did not the IPv6 change at the time it was
      submitted.

      gianfar: Add WAKE_UCAST and "wake-on-filer" support

      This enables eTSEC's filer (Rx parser) and the FGPI Rx
      interrupt (Filer General Purpose Interrupt) as a wakeup
      source event.

      Upon entering suspend state, the eTSEC filer is given
      a rule to match incoming L2 unicast packets.  A packet
      matching the rule will be enqueued in the Rx ring and
      a FGPI Rx interrupt will be asserted by the filer to
      wakeup the system.  Other packet types will be dropped.
      On resume the filer table is restored to the content
      before entering suspend state.
      The set of rules from gfar_filer_config_wol() could be
      extended to implement other WoL capabilities as well.

      The "fsl,wake-on-filer" DT binding enables this capability
      on certain platforms that feature the necessary power
      management infrastructure, targeting mainly printing and
      imaging applications.

      arm64: mm: remove dsb from update_mmu_cache

      update_mmu_cache() consists of a dsb(ishst) instruction so that new user
      mappings are guaranteed to be visible to the page table walker on

      In reality this can be a very expensive operation which is rarely needed.
      Removing this barrier shows a modest improvement in hackbench scores and

      arm64: switch_mm: simplify mm and CPU checks

      switch_mm performs some checks to try and avoid entering the ASID
      allocator:

        (1) If we're switching to the init_mm (no user mappings), then simply
            set a reserved TTBR0 value with no page table (the zero page)

        (2) If prev == next *and* the mm_cpumask indicates that we've run on
            this CPU before, then we can skip the allocator.

      However, there is plenty of redundancy here. With the new ASID allocator,
      if prev == next, then we know that our ASID is valid and do not need to
      worry about re-allocation. Consequently, we can drop the mm_cpumask check
      in (2) and move the prev == next check before the init_mm check, since
      if prev == next == init_mm then there's nothing to do.

      arm64: mm: rewrite ASID allocator and MM context-switching code

      Our current switch_mm implementation suffers from a number of problems:

        (1) The ASID allocator relies on IPIs to synchronise the CPUs on a
            rollover event

        (2) Because of (1), we cannot allocate ASIDs with interrupts disabled
            and therefore make use of a TIF_SWITCH_MM flag to postpone the
            actual switch to finish_arch_post_lock_switch

        (3) We run context switch with a reserved (invalid) TTBR0 value, even
            though the ASID and pgd are updated atomically

        (4) We take a global spinlock (cpu_asid_lock) during context-switch

        (5) We use h/w broadcast TLB operations when they are not required
            (e.g. in flush_context)

      This patch addresses these problems by rewriting the ASID algorithm to
      match the bitmap-based arch/arm/ implementation more closely. This in
      turn allows us to remove much of the complications surrounding switch_mm,
      including the ugly thread flag.

      __local_flush_icache_all also implies an isb, since it is intended to be

      instead of numa_node_id() to get the nearest node with memory which
      better supports memoryless nodes.

      Anjali fixes an issue from Dan Carpenter <dan.carpenter@xxxxxxxxxx>,
      to resolve a memory leak in X722 RSS configuration path, where we should
      free the memory allocated before exiting.

      Shannon modifies the drivers to ensure we have the spinlocks before we
      clear the ARQ and ASQ management registers.  In addition, we widen the
      locked portion insert a sanity check to ensure we are working with safe
      register values.

      Mitch fixes an issue where under certain circumstances, we can get an
      extra VF_RESOURCES message from the PF driver at runtime.  When this
      occurs, we need to parse it because our VSI may have changed and that
      will affect the relationship with the PF driver.  But this parsing also
      blows away our current MAC address, so resolve the issue by restoring
      the current MAC address from the netdev struct after we parse the
      resource message.

      Add additional error reporting to the generic DSA code, so it's easier
      to debug when things go wrong.  This was useful when initially bringing
      up 88e6176 on a new board.

      net: dsa: mv88e6xxx: remove link polling

      The link status is polled by the generic phy layer, there's no need to
      duplicate that polling with additional polling.  This additional polling
      adds additional MDIO traffic, and races with the generic phy layer,
      resulting in missing or duplicated link status messages.

      selftests/x86: Add a test for vDSO unwinding

      While the kernel itself doesn't use DWARF unwinding, user code
      expects to be able to unwind the vDSO.  The vsyscall
      (AT_SYSINFO) entry is manually CFI-annotated, and this tests
      that it unwinds correctly.

      I tested the test by incorrectly annotating __kernel_vsyscall,
      and the test indeed fails if I do that.

       "This patch series fixes up a couple of architecture issues where
        strscpy wasn't configured correctly (missing on h8300, duplicating
        local and asm-generic copies on powerpc and tile).

        It also adds a use of zero_bytemask() to the final store for strscpy
        to avoid writing uninitialized data to the destination.  However, to
        make this work we had to add support for zero_bytemask() to the two
        architectures that didn't have it (alpha and tile), because they were
        providing their own local copies, but didn't provide the
        zero_bytemask() that was previously only required when building with
        CONFIG_DCACHE_WORD_ACCESS"

      [ Side note: there is still no actual users of strscpy except for the
        one preexisting use in arch/tile that predates the generic version.
        So this is all about fixing the infrastructure so that we eventually
        can start using it.  - Linus ]

      Revert "fs: do not prefault sys_write() user buffer pages"

      This reverts commit 998ef75ddb5709bbea0bf1506cd2717348a3c647.

      The commit itself does not appear to be buggy per se, but it is exposing
      a bug in ext4 (and Ted thinks ext3 too, but we solved that by getting
      rid of it).  It's too late in the release cycle to really worry about
      this, even if Dave Hansen has a patch that may actually fix the
      underlying ext4 problem.  We can (and should) revisit this for the next
      release.

      The problem is that moving the prefaulting later now exposes a special
      case with partially successful writes that isn't handled correctly.  And
      the prefaulting likely isn't normally even that much of a performance
      issue - it looks like at least one reason Dave saw this in his
      performance tests is that he also ran them on Skylake that now supports
      the new SMAP code, which makes the normally very cheap user space
      prefaulting noticeably more expensive.

      allocate a fixed number of pages for the scheduled process area. This
      will limit us to 958 processes with 2 x 64K pages. If we try to use more
      processes than that we'd probably overrun the buffer and corrupt memory
      or crash.

      AFUs that require three or more interrupts per process will not be
      affected as they are already limited to less processes than that, but we
      could hit it on an AFU that requires 0, 1 or 2 interrupts per process,
      or when using 4K pages.

      This patch moves the initialisation of the num_procs to before the SPA
      allocation so that enough pages will be allocated for the number of
      processes that the AFU supports.

      drm/qxl: avoid dependency lock

      qxl_bo_unref calls drm_gem_object_unreference_unlocked which
      locks dev->struct_mutex. However this lock could be already
      locked if the call came from qxl_gem_object_free.
      As we don't need to call qxl_bo_ref/qxl_bo_unref cause
      qxl_release_list_add will hold a reference by itself avoid
      to call them and the possible deadlock.

      drm/qxl: avoid buffer reservation in qxl_crtc_page_flip

      This avoid a dependency lock error.
      According to https://lwn.net/Articles/548909/ users of WW mutex API
      should avoid using different context.
      When a buffer is reserved with qxl_bo_reserve a ww_mutex_lock without
      context is used. However during qxl_draw_dirty_fb different locks
      with specific context are used.
      This is detected during a machine booting with a debug kernel with lock
      dependency checking enabled.
      Like many other function in this file to avoid this problem object
      pinning is used. Once the object is pinned is not necessary to keep
      the lock so it can be released avoiding the locking problem.

      read the local name and print it out. This is only done during setup
      stage and only once before loading the firmware and once after loading

      Input: ads7846 - correct the value got from SPI

      According to the touch controller spec, SPI return a 16 bit value, only 12
      bits are valid, they are bit[14-3].

      The value of MISO and MOSI can be configured when SPI is in idle mode.
      Currently this touch driver assumes the SPI bus sets the MOSI and MISO in
      low level when SPI bus is in idle mode. So the bit[15] of the value got
      from SPI bus is always 0. But when SPI bus congfigures the MOSI and MISO 
in
      high level during the SPI idle mode, the bit[15] of the value get from SPI
      is always 1. If bit[15] is not masked, we may get the wrong value.

      Mask the invalid bit to make sure the correct value gets returned.
      Regardless of the SPI bus idle configuration.

      1. Rename __rcu_sync_is_idle() to rcu_sync_lockdep_assert() and

      2. Change rcu_sync_is_idle() to return rsp->gp_state == GP_IDLE
         unconditonally, this way we can remove the same check from
         rcu_sync_lockdep_assert() and clearly isolate the debugging
         code.

      Note: rcu_sync_enter()->wait_event(gp_state == GP_PASSED) needs
      another CONFIG_PROVE_RCU check, the same as is done in ->sync(); but
      this needs some simple preparations in the core RCU code to avoid the

      locking/percpu-rwsem: Clean up the lockdep annotations in 
percpu_down_read()

      Based on Peter Zijlstra's earlier patch.

      Change percpu_down_read() to use __down_read(), this way we can
      do rwsem_acquire_read() unconditionally at the start to make this
      code more symmetric and clean.

      locking/percpu-rwsem: Make use of the rcu_sync infrastructure

      Currently down_write/up_write calls synchronize_sched_expedited()
      twice, which is evil.  Change this code to rely on rcu-sync primitives.
      This avoids the _expedited "big hammer", and this can be faster in
      the contended case or even in the case when a single thread does
      down_write/up_write in a loop.

      Of course, a single down_write() will take more time, but otoh it
      will be much more friendly to the whole system.

      To simplify the review this patch doesn't update the comments, fixed
      by the next change.

      rcu: Create rcu_sync infrastructure

      The rcu_sync infrastructure can be thought of as infrastructure to be
      used to implement reader-writer primitives having extremely lightweight
      readers during times when there are no writers.  The first use is in
      the percpu_rwsem used by the VFS subsystem.

      This infrastructure is functionally equivalent to

              struct rcu_sync_struct {
                      atomic_t counter;
              };

        /* Check possibility of fast-path read-side operations. */
              static inline bool rcu_sync_is_idle(struct rcu_sync_struct *rss)
              {
                      return atomic_read(&rss->counter) == 0;
              }

        /* Tell readers to use slowpaths. */
              static inline void rcu_sync_enter(struct rcu_sync_struct *rss)
              {
                      atomic_inc(&rss->counter);
                      synchronize_sched();
              }

        /* Allow readers to once again use fastpaths. */
              static inline void rcu_sync_exit(struct rcu_sync_struct *rss)
              {
                      synchronize_sched();
                      atomic_dec(&rss->counter);
              }

      The main difference is that it records the state and only calls
      synchronize_sched() if required.  At least some of the calls to
      synchronize_sched() will be optimized away when rcu_sync_enter() and
      rcu_sync_exit() are invoked repeatedly in quick succession.

      locktorture: Support rtmutex torturing

      Real time mutexes is one of the few general primitives
      that we do not have in locktorture. Address this -- a few
      considerations:

      o To spice things up, enable competing thread(s) to become
      rt, such that we can stress different prio boosting paths
      in the rtmutex code. Introduce a ->task_boost callback,
      only used by rtmutex-torturer. Tasks will boost/deboost
      around every 50k (arbitrarily) lock/unlock operations.

      o Hold times are similar to what we have for other locks:
      only occasionally having longer hold times (per ~200k ops).
      So we roughly do two full rt boost+deboosting ops with
      short hold times.

      documentation: Correct doc to use rcu_dereference_protected

      As there is lots of misinformation and outdated information on the
      Internet about nearly all topics related to the kernel, I thought it
      would be best if I based my RCU code on the guidelines of the examples
      in the Documentation/ tree of the latest kernel. One thing that stuck
      out when reading the whatisRCU.txt document was, "interesting how we
      don't need any function to dereference rcu protected pointers when doing
      updates if a lock is held. I wonder how static analyzers will work with
      that." Then, a few weeks later, upon discovering sparse's __rcu support,
      I ran it over my code, and lo and behold, things weren't done right.
      Examining other RCU usages in the kernel reveal consistent usage of
      rcu_dereference_protected, passing in lockdep_is_held as the
      conditional. So, this patch adds that idiom to the documentation, so
      that others ahead of me won't endure the same exercise.

      rculist: Make list_entry_rcu() use lockless_dereference()

      The current list_entry_rcu() implementation copies the pointer to a stack
      variable, then invokes rcu_dereference_raw() on it.  This results in an
      additional store-load pair.  Now, most compilers will emit normal store
      and load instructions, which might seem to be of negligible overhead,
      but this results in a load-hit-store situation that can cause surprisingly
      long pipeline stalls, even on modern microprocessors.  The problem is
      that it takes time for the store to get the store buffer updated, which
      can delay the subsequent load, which immediately follows.

      This commit therefore switches to the lockless_dereference() primitive,
      which does not expect the __rcu annotations (that are anyway not present
      in the list_head structure) and which, like rcu_dereference_raw(),
      does not check for an enclosing RCU read-side critical section.
      Most importantly, it does not copy the pointer, thus avoiding the
      load-hit-store overhead.

      Commit commit 4cdfc175c25c89ee ("rcu: Move quiescent-state forcing
      into kthread") started the process of folding the old ->fqs_state into
      ->gp_state, but did not complete it.  This situation does not cause
      any malfunction, but can result in extremely confusing trace output.
      This commit completes this task of eliminating ->fqs_state in favor
      of ->gp_state.

      The old ->fqs_state was also used to decide when to collect dyntick-idle
      snapshots.  For this purpose, we add a boolean variable into the kthread,
      which is set on the first call to rcu_gp_fqs() for a given grace period
      and clear otherwise.

      rcu: Move preemption disabling out of __srcu_read_lock()

      Currently, __srcu_read_lock() cannot be invoked from restricted
      environments because it contains calls to preempt_disable() and
      preempt_enable(), both of which can invoke lockdep, which is a bad
      idea in some restricted execution modes.  This commit therefore moves
      the preempt_disable() and preempt_enable() from __srcu_read_lock()
      to srcu_read_lock().  It also inserts the preempt_disable() and
      preempt_enable() around the call to __srcu_read_lock() in do_exit().

      This commit makes the RCU CPU stall warning message print online/offline
      indications immediately after a hyphen following the CPU number.  A "O"
      indicates that the global CPU-hotplug system believes that the CPU is
      online, a "o" that RCU perceived the CPU to be online at the beginning
      of the current expedited grace period, and an "N" that RCU currently
      believes that it will perceive the CPU as being online at the beginning
      of the next expedited grace period, with "." otherwise for all three
      indications.  So for CPU 10, you would normally see "10-OoN:" indicating
      that everything believes that the CPU is online.

      rcu: Eliminate panic when silly boot-time fanout specified

      This commit loosens rcutree.rcu_fanout_leaf range checks
      and replaces a panic() with a fallback to compile-time values.
      This fallback is accompanied by a WARN_ON(), and both occur when the
      rcutree.rcu_fanout_leaf value is too small to accommodate the number of
      CPUs.  For example, given the current four-level limit for the rcu_node
      tree, a system with more than 16 CPUs built with CONFIG_FANOUT=2 must
      have rcutree.rcu_fanout_leaf larger than 2.

      rcu: Don't disable preemption for Tiny and Tree RCU readers

      Because preempt_disable() maps to barrier() for non-debug builds,
      it forces the compiler to spill and reload registers.  Because Tree
      RCU and Tiny RCU now only appear in CONFIG_PREEMPT=n builds, these
      barrier() instances generate needless extra code for each instance of
      rcu_read_lock() and rcu_read_unlock().  This extra code slows down Tree
      RCU and bloats Tiny RCU.

      This commit therefore removes the preempt_disable() and preempt_enable()
      from the non-preemptible implementations of __rcu_read_lock() and
      __rcu_read_unlock(), respectively.  However, for debug purposes,
      preempt_disable() and preempt_enable() are still invoked if
      CONFIG_PREEMPT_COUNT=y, because this allows detection of sleeping inside
      atomic sections in non-preemptible kernels.

      However, Tiny and Tree RCU operates by coalescing all RCU read-side
      critical sections on a given CPU that lie between successive quiescent
      states.  It is therefore necessary to compensate for removing barriers
      from __rcu_read_lock() and __rcu_read_unlock() by adding them to a
      couple of the RCU functions invoked during quiescent states, namely to
      rcu_all_qs() and rcu_note_context_switch().  However, note that the latter
      is more paranoia than necessity, at least until link-time optimizations
      become more aggressive.

      This is based on an earlier patch by Paul E. McKenney, fixing
      a bug encountered in kernels built with CONFIG_PREEMPT=n and
      CONFIG_PREEMPT_COUNT=y.

      The new locktorture rtmutex_lock tests exercise priority boosting, which

      perf/x86/intel/uncore: Fix multi-segment problem of 
perf_event_intel_uncore

      In multi-segment system, uncore devices may belong to buses whose segment
      number is other than 0:

        ....
        0000:ff:10.5 System peripheral: Intel Corporation Xeon E5 v3/Core i7 
Scratchpad & Semaphore Registers (rev 03)
        ...

        0001:ff:10.5 System peripheral: Intel Corporation Xeon E5 v3/Core i7 
Scratchpad & Semaphore Registers (rev 03
        ...

      In that case, relation of bus number and physical id may be broken
      because "uncore_pcibus_to_physid" doesn't take account of PCI segment.
      For example, bus 0000:ff and 0001:ff uses the same entry of
      "uncore_pcibus_to_physid" array.

      This patch fixes this problem by introducing the segment-aware 
pci2phy_map instead.

      perf/x86: Add Intel cstate PMUs support

      This patch adds new PMUs to support cstate related free running
      (read-only) counters. These counters may be used simultaneously by other
      tools, such as turbostat. However, it still make sense to implement them
      in perf. Because we can conveniently collect them together with other
      events, and allow to use them from tools without special MSR access
      code.

      These counters include CORE_C*_RESIDENCY and PKG_C*_RESIDENCY.
      According to counters' scope and category, two PMUs are registered with
      the perf_event core subsystem.

       - 'cstate_core': The counter is available for each physical core. The
                        counters include CORE_C*_RESIDENCY.

       - 'cstate_pkg':  The counter is available for each physical package. The
                        counters include PKG_C*_RESIDENCY.

      The events are exposed in sysfs for use by perf stat and other tools.
      The files are:

        /sys/devices/cstate_core/events/c*-residency
        /sys/devices/cstate_pkg/events/c*-residency

      These events only support system-wide mode counting.
      The /sys/devices/cstate_*/cpumask file can be used by tools to figure
      out which CPUs to monitor by default.

      The PMU type (attr->type) is dynamically allocated and is available from
      /sys/devices/core_misc/type and /sys/device/cstate_*/type.

      Sampling is not supported.

      Here is an example.

       - To caculate the fraction of time when the core is running in C6 state
         CORE_C6_time% = CORE_C6_RESIDENCY / TSC

       # perf stat -x, -e"cstate_core/c6-residency/,msr/tsc/" -C0 -- taskset -c 
0 sleep 5

         11838820015,,cstate_core/c6-residency/,5175919658,100.00
         11877130740,,msr/tsc/,5175922010,100.00

       For sleep, 99.7% of time we ran in C6 state.

       # perf stat -x, -e"cstate_core/c6-residency/,msr/tsc/" -C0 -- taskset -c 
0 busyloop

      This commit allows installing a custom reg_update_bits function for cases 
where
      the hardware provides a mechanism to set or clear register bits without a
      read/modify/write cycle. Such is the case with the Microchip ENCX24J600.

      If a custom reg_update_bits function is provided, it will only be used 
against
      volatile registers.

      sched/core: Drop unlikely behind BUG_ON()

      (1) For !CONFIG_BUG cases, the bug call is a no-op, so we couldn't care
          less and the change is ok.

      (2) PPC and MIPS, which HAVE_ARCH_BUG_ON, do not rely on branch 
predictions
          as it seems to be pointless [1] and thus callers should not be trying 
to
          push an optimization in the first place.

      (3) For CONFIG_BUG and !HAVE_ARCH_BUG_ON cases, BUG_ON() contains an
          unlikely compiler flag already.

      Hence, we can drop unlikely behind BUG_ON().

      This alternative patch solves the problem by not calling
      sched_info_{de,}queued() in {de,en}queue_task(). Therefore the
      sched_info state is preserved and things work as expected.

      By inlining the {de,en}queue_task() functions the new condition
      becomes (mostly) a compile-time constant and we'll not emit any new
      branch instructions.

      It even shrinks the code (due to inlining {en,de}queue_task()):

      sched/numa: Fix task_tick_fair() from disabling numa_balancing

      If static branch 'sched_numa_balancing' is enabled, it should kickstart
      NUMA balancing through task_tick_numa(). However the following commit:

        2a595721a1fa ("sched/numa: Convert sched_numa_balancing to a 
static_branch")

      erroneously disables this.

      Fix this anomaly by enabling task_tick_numa() when the static branch
      'sched_numa_balancing' is enabled.

      sched/core: More notrace annotations

      preempt_schedule_common() is marked notrace, but it does not use
      _notrace() preempt_count functions and __schedule() is also not marked
      notrace, which means that its perfectly possible to end up in the
      tracer from preempt_schedule_common().

      Steve says:

        | Yep, there's some history to this. This was originally the issue that
        | caused function tracing to go into infinite recursion. But now we have
        | preempt_schedule_notrace(), which is used by the function tracer, and
        | that function must not be traced till preemption is disabled.
        |
        | Now if function tracing is running and we take an interrupt when
        | NEED_RESCHED is set, it calls
        |
        |   preempt_schedule_common() (not traced)
        |
        | But then that calls preempt_disable() (traced)
        |
        | function tracer calls preempt_disable_notrace() followed by
        | preempt_enable_notrace() which will see NEED_RESCHED set, and it will
        | call preempt_schedule_notrace(), which stops the recursion, but
        | still calls __schedule() here, and that means when we return, we call
        | the __schedule() from preempt_schedule_common().
        |
        | That said, I prefer this patch. Preemption is disabled before calling
        | __schedule(), and we get rid of a one round recursion with the
        | scheduler.

      sched/core: Robustify preemption leak checks

      When we warn about a preempt_count leak; reset the preempt_count to
      the known good value such that the problem does not ripple forward.

      This is most important on x86 which has a per cpu preempt_count that is
      not saved/restored (after this series). So if you schedule with an
      invalid (!2*PREEMPT_DISABLE_OFFSET) preempt_count the next task is
      messed up too.

      Enforcing this invariant limits the borkage to just the one task.

      sched/core: Create preempt_count invariant

      Assuming units of PREEMPT_DISABLE_OFFSET for preempt_count() numbers.

      Now that TASK_DEAD no longer results in preempt_count() == 3 during
      scheduling, we will always call context_switch() with preempt_count()
      == 2.

      However, we don't always end up with preempt_count() == 2 in
      finish_task_switch() because new tasks get created with
      preempt_count() == 1.

      Create FORK_PREEMPT_COUNT and set it to 2 and use that in the right
      places. Note that we cannot use INIT_PREEMPT_COUNT as that serves
      another purpose (boot).

      After this, preempt_count() is invariant across the context switch,
      with exception of PREEMPT_ACTIVE.

      sched/core: Rework TASK_DEAD preemption exception

      TASK_DEAD is special in that the final schedule call from do_exit()
      must be done with preemption disabled.

      This means we end up scheduling with a preempt_count() higher than
      usual (3 instead of the 'expected' 2).

      Since future patches will want to rely on an invariant
      preempt_count() value during schedule, fix this up.

      sched/core: Simplify INIT_PREEMPT_COUNT

      As per the following commit:

        d86ee4809d03 ("sched: optimize cond_resched()")

      we need PREEMPT_ACTIVE to avoid cond_resched() from working before
      the scheduler is set up.

      However, keeping preemption disabled should do the same thing
      already, making the PREEMPT_ACTIVE part entirely redundant.

      The only complication is !PREEMPT_COUNT kernels, where
      PREEMPT_DISABLED ends up being 0. Instead we use an unconditional
      PREEMPT_OFFSET to set preempt_count() even on !PREEMPT_COUNT
      kernels.

      sched/core: Fix TASK_DEAD race in finish_task_switch()

      So the problem this patch is trying to address is as follows:

              CPU0                            CPU1

              context_switch(A, B)
                                              ttwu(A)
                                                LOCK A->pi_lock
                                                A->on_cpu == 0
              finish_task_switch(A)
                prev_state = A->state  <-.
                WMB                      |
                A->on_cpu = 0;           |
                UNLOCK rq0->lock         |
                                         |    context_switch(C, A)
                                         `--  A->state = TASK_DEAD
                prev_state == TASK_DEAD
                  put_task_struct(A)
                                              context_switch(A, C)
                                              finish_task_switch(A)
                                                A->state == TASK_DEAD
                                                  put_task_struct(A)

      The argument being that the WMB will allow the load of A->state on CPU0
      to cross over and observe CPU1's store of A->state, which will then
      result in a double-drop and use-after-free.

      Now the comment states (and this was true once upon a long time ago)
      that we need to observe A->state while holding rq->lock because that
      will order us against the wakeup; however the wakeup will not in fact
      acquire (that) rq->lock; it takes A->pi_lock these days.

      We can obviously fix this by upgrading the WMB to an MB, but that is
      expensive, so we'd rather avoid that.

      The alternative this patch takes is: smp_store_release(&A->on_cpu, 0),
      which avoids the MB on some archs, but not important ones like ARM.

      4246a0b63bd8 ("block: add a bi_error field to struct bio") changed
      the function to check the original bio's bi_error, which is 0.

      Without this fix, clone's error is ignored and reported to the
      original request as success.  Thus data corruption will be observed.

      Instead of reporting (via shared_info) the maximum possible size of
      the P2M, hint at the last PFN which might be populated.  This hint is
      increased as new leaves are added to the P2M (in the expectation that
      they will be used for populated entries).

      ath10k: use pre-allocated DMA buffer in Tx

      ath10k driver is using dma_pool_alloc per packet and dma_pool_free
      in coresponding at Tx completion.
      Use of pre-allocated DMA buffer in Tx will improve saving CPU resource
      by 5% while it consumes about 56KB memory more as trade off.

      ath10k: use Rx decap mode configured when driver registered

      ath10k is using Native WiFi mode as default mode for both of
      Tx and Rx path, but it could be changed when driver registers
      with a module parameter for specific purpose such as mesh.

      The Rx decap mode sent to firmware during WMI initialization should
      use the same mode that driver configured at its registration stage
      in case of using raw mode, so that host driver receives MAC frame
      header containing necessary fields such as QoS and Mesh Control
      and uses them in right way to make data traffic work.

      x86/mm: Warn on W^X mappings

      Warn on any residual W+X mappings after setting NX
      if DEBUG_WX is enabled.  Introduce a separate
      X86_PTDUMP_CORE config that enables the code for
      dumping the page tables without enabling the debugfs
      interface, so that DEBUG_WX can be enabled without
      exposing the debugfs interface.  Switch EFI_PGT_DUMP
      to using X86_PTDUMP_CORE so that it also does not require
      enabling the debugfs interface.

      On success it prints this to the kernel log:

        x86/mm: Checked W+X mappings: passed, no W+X pages found.

      On failure it prints a warning and a count of the failed pages:

      Merge tag 'perf-core-for-mingo' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      User visible changes:

        - Switch the default callchain output mode to 'graph,0.5,caller', to 
make it
          look like the default for other tools, reducing the learning curve for
          people used to 'caller' based viewing. (Arnaldo Carvalho de Melo)

        - Implement column based horizontal scrolling in the hists browser 
(top, report),
          making it possible to use the TUI for things like 'perf mem report' 
where
          there are many more columns than can fit in a terminal. (Arnaldo 
Carvalho de Melo)

        - Support sorting by symbol_iaddr with perf.data files produced by
          'perf mem record'. (Don Zickus)

        - Display DATA_SRC sample type bit, i.e. when running 'perf evlist -v' 
the
          "DATA_SRC" wasn't appearing when set, fix it to look like: (Jiri Olsa)

            cpu/mem-loads/pp: ...SNIP... sample_type: 
IP|TID|TIME|ADDR|CPU|PERIOD|DATA_SRC

        - Introduce the 'P' event modifier, meaning 'max precision level, 
please', i.e.:

           $ perf record -e cycles:P usleep 1

          Is now similar to:

           $ perf record usleep 1

          Useful, for instance, when specifying multiple events. (Jiri Olsa)

        - Make 'perf -v' and 'perf -h' work. (Jiri Olsa)

        - Fail properly when pattern matching fails to find a tracepoint, i.e.
          '-e non:existent' was being correctly handled, with a proper error 
message
          about that not being a valid event, but '-e non:existent*' wasn't,
          fix it. (Jiri Olsa)

      Infrastructure changes:

        - Separate arch specific entries in 'perf test' and add an 'Intel CQM' 
one
          to be fun on x86 only. (Matt Fleming)

      This happened because the same transaction handle created a large number
      of block groups and while finalizing their creation (inserting new items
      and updating existing items in the chunk and device trees) a new metadata
      extent had to be allocated and no free space was found in the current
      metadata block groups, which made find_free_extent() attempt to allocate
      a new block group via do_chunk_alloc(). However at do_chunk_alloc() we
      ended up allocating a new system chunk too and exceeded the threshold
      of 2Mb of reserved chunk bytes, which makes do_chunk_alloc() enter the
      final part of block group creation again (at
      btrfs_create_pending_block_groups()) and attempt to lock again the root
      of the chunk tree when it's already write locked by the same task.

      Similarly we can deadlock on extent tree nodes/leafs if while we are
      running delayed references we end up creating a new metadata block group
      in order to allocate a new node/leaf for the extent tree (as part of
      a CoW operation or growing the tree), as btrfs_create_pending_block_groups
      inserts items into the extent tree as well. In this case we get the
      following trace:

      Fix this by never recursing into the finalization phase of block group

      creation while running delayed references.

      Btrfs: update fix for read corruption of compressed and shared extents

      My previous fix in commit 005efedf2c7d ("Btrfs: fix read corruption of
      compressed and shared extents") was effective only if the compressed
      extents cover a file range with a length that is not a multiple of 16
      pages. That's because the detection of when we reached a different range
      of the file that shares the same compressed extent as the previously
      processed range was done at extent_io.c:__do_contiguous_readpages(),
      which covers subranges with a length up to 16 pages, because
      extent_readpages() groups the pages in clusters no larger than 16 pages.
      So fix this by tracking the start of the previously processed file
      range's extent map at extent_readpages().

      The following test case for fstests reproduces the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"

      Btrfs: send, fix corner case for reference overwrite detection

      When the inode given to did_overwrite_ref() matches the current progress
      and has a reference that collides with the reference of other inode that
      has the same number as the current progress, we were always telling our
      caller that the inode's reference was overwritten, which is incorrect
      because the other inode might be a new inode (different generation number)
      in which case we must return false from did_overwrite_ref() so that its
      callers don't use an orphanized path for the inode (as it will never be
      orphanized, instead it will be unlinked and the new inode created later).

      The following test case for fstests reproduces the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"

        tmp=/tmp/$$

      perf hists browser: Implement horizontal scrolling

      Do it using the recently introduced ui_brower scrolling mode, setting
      ui_browser.columns to the number of sort columns and then, when
      rendering each line, skipping as many initial columns as the user
      pressed the right arrow.

      As the user presses the left arrow, the ui_browser code will remove the
      scrolling counter and the left scrolling takes place.

      The right arrow key was an alias for ENTER, so people used to press it
      may get a bit annoyed at first, sorry! Ditto for ESC and the left key.

      Callchains can be left as is or we can, when rendering the Symbol
      column, store the at what position on the screen it is and then
      using ui_browser__gotorc() to print it from there, i.e. the callchain
      would move around with the symbol.

      Leaving it as is, i.e. at a fixed position, close to the left, saves
      precious screen real state for it, so I'm inclined to leave it as is
      now.

      perf ui browser: Optional horizontal scrolling key binding

      If the classes derived from ui_browser want to do some sort of
      horizontal scrolling, they have just to set ui_browser->columns to
      the number of columns available.

      Those columns can be the number of characters on the screen, if what is
      desired is to scroll character by character, or the number of columns in
      a spreadsheet like table.

      This is what the hist_browser will do, skipping ui_browser->horiz_scroll
      columns when rendering each of its lines.

      perf tests: Add Intel CQM test

      Peter reports that it's possible to trigger a WARN_ON_ONCE() in the
      Intel CQM code by combining a hardware event and an Intel CQM
      (software) event into a group. Unfortunately, the perf tools are not
      able to create this bundle and we need to manually construct a test
      case.

      For posterity, record Peter's proof of concept test case in tools/perf
      so that it presents a model for how we can perform architecture
      specific tests, or "arch tests", in perf in the future.

      The particular issue triggered in the test case is that when the
      counter for the hardware event overflows and triggers a PMI we'll read
      both the hardware event and the software event counters.
      Unfortunately, for CQM that involves performing an IPI to read the CQM
      event counters on all sockets, which in NMI context triggers the
      WARN_ON_ONCE().

      perf tests: Add arch tests

      Tests that only make sense for some architectures currently live in
      the same place as the generic tests. Move out the x86-specific tests
      into tools/perf/arch/x86/tests and define an 'arch_tests' array, which
      is the list of tests that only apply to the build architecture.

      The main idea is to encourage developers to add arch tests to build
      out perf's test coverage, without dumping everything in
      tools/perf/tests.

      perf annotate: Fix sizeof_sym_hist overflow issue

      The annotated_source::sizeof_sym_hist could easily overflow int size,
      resulting in crash in __symbol__inc_addr_samples.

      Changing its type int size_t as was probably intended from beginning
      based on the initialization code in symbol__alloc_hist.

      RDS: IB: split mr pool to improve 8K messages performance

      8K message sizes are pretty important usecase for RDS current
      workloads so we make provison to have 8K mrs available from the pool.
      Based on number of SG's in the RDS message, we pick a pool to use.

      Also to make sure that we don't under utlise mrs when say 8k messages
      are dominating which could lead to 8k pull being exhausted, we fall-back
      to 1m pool till 8k pool recovers for use.

      This helps to at least push ~55 kB/s bidirectional data which
      is a nice improvement.

      RDS: IB: ack more receive completions to improve performance

      For better performance, we split the receive completion IRQ handler. That
      lets us acknowledge several WCE events in one call. We also limit the WC
      to max 32 to avoid latency. Acknowledging several completions in one call
      instead of several calls each time will provide better performance since
      less mutual exclusion locks are being performed.

      In next patch, send completion is also split which re-uses the poll_cq()
      and hence the code is moved to ib_cm.c

      RDS: use rds_send_xmit() state instead of RDS_LL_SEND_FULL

      In Transport indepedent rds_sendmsg(), we shouldn't make decisions based
      on RDS_LL_SEND_FULL which is used to manage the ring for RDMA based
      transports. We can safely issue rds_send_xmit() and the using its
      return value take decision on deferred work. This will also fix
      the scenario where at times we are seeing connections stuck with
      the LL_SEND_FULL bit getting set and never cleared.

      We kick krdsd after any time we see -ENOMEM or -EAGAIN from the
      ring allocation code.

      RDS: defer the over_batch work to send worker

      Current process gives up if its send work over the batch limit.
      The work queue will get  kicked to finish off any other requests.
      This fixes remainder condition from commit 443be0e5affe ("RDS: make
      sure not to loop forever inside rds_send_xmit").

      The restart condition is only for the case where we reached to
      over_batch code for some other reason so just retrying again
      before giving up.

      While at it, make sure we use already available 'send_batch_count'
      parameter instead of magic value. The batch count threshold value
      of 1024 came via commit 443be0e5affe ("RDS: make sure not to loop
      forever inside rds_send_xmit"). The idea is to process as big a
      batch as we can but at the same time we don't hold other waiting
      processes for send. Hence back-off after the send_batch_count
      limit (1024) to avoid soft-lock ups.

      This is the arm64 portion of commit 45cac65b0fcd ("readahead: fault

      the initial port and has since gone unnoticed. The original commit says:

      > .fault now can retry.  The retry can break state machine of .fault.  In
      > filemap_fault, if page is miss, ra->mmap_miss is increased.  In the 
second
      > try, since the page is in page cache now, ra->mmap_miss is decreased.  
And
      > these are done in one fault, so we can't detect random mmap file access.
      >
      > Add a new flag to indicate .fault is tried once.  In the second try, 
skip
      > ra->mmap_miss decreasing.  The filemap_fault state machine is ok with 
it.

      With this change, Mark reports that:

      > Random read improves by 250%, sequential read improves by 40%, and
      > random write by 400% to an eMMC device with dm crypto wrapped around it.

      The __build_packet_message function fills a nfulnl_msg_packet_timestamp
      structure that uses 64-bit seconds and is therefore y2038 safe, but
      it uses an intermediate 'struct timespec' which is not.

      This trivially changes the code to use 'struct timespec64' instead,
      to correct the result on 32-bit architectures.

      ALSA: synth: Fix conflicting OSS device registration on AWE32

      When OSS emulation is loaded on ISA SB AWE32 chip, we get now kernel
      warnings like:
        WARNING: CPU: 0 PID: 2791 at fs/sysfs/dir.c:31 
sysfs_warn_dup+0x51/0x80()
        sysfs: cannot create duplicate filename 
'/devices/isa/sbawe.0/sound/card0/seq-oss-0-0'

      It's because both emux synth and opl3 drivers try to register their
      OSS device object with the same static index number 0.  This hasn't
      been a big problem until the recent rewrite of device management code
      (that exposes sysfs at the same time), but it's been an obvious bug.

      This patch works around it just by using a different index number of
      emux synth object.  There can be a more elegant way to fix, but it's
      enough for now, as this code won't be touched so often, in anyway.

      Merge branch 'asix-rx-mem-handling'

      Mark Craske says:

      ====================
      Improve ASIX RX memory allocation error handling

      The ASIX RX handler algorithm is weak on error handling.
      There is a design flaw in the ASIX RX handler algorithm because the
      implementation for handling RX Ethernet frames for the DUB-E100 C1 can
      have Ethernet frames spanning multiple URBs. This means that payload data
      from more than 1 URB is sometimes needed to fill the socket buffer with a
      complete Ethernet frame. When the URB with the start of an Ethernet frame
      is received then an attempt is made to allocate a socket buffer. If the
      memory allocation fails then the algorithm sets the buffer pointer member
      to NULL and the function exits (no crash yet). Subsequently, the RX hander
      is called again to process the next URB which assumes there is a socket
      buffer available and the kernel crashes when there is no buffer.

      This patchset implements an improvement to the RX handling algorithm to
      avoid a crash when no memory is available for the socket buffer.

      The patchset will apply cleanly to the net-next master branch but the
      created kernel has not been tested. The driver was tested on ARM kernels
      v3.8 and v3.14 for a commercial product.

      asix: Continue processing URB if no RX netdev buffer

      Avoid a loss of synchronisation of the Ethernet Data header 32-bit
      word due to a failure to get a netdev socket buffer.

      The ASIX RX handling algorithm returned 0 upon a failure to get
      an allocation of a netdev socket buffer. This causes the URB
      processing to stop which potentially causes a loss of synchronisation
      with the Ethernet Data header 32-bit word. Therefore, subsequent
      processing of URBs may be rejected due to a loss of synchronisation.
      This may cause additional good Ethernet frames to be discarded
      along with outputting of synchronisation error messages.

      Implement a solution which checks whether a netdev socket buffer
      has been allocated before trying to copy the Ethernet frame into
      the netdev socket buffer. But continue to process the URB so that
      synchronisation is maintained. Therefore, only a single Ethernet
      frame is discarded when no netdev socket buffer is available.

      asix: On RX avoid creating bad Ethernet frames

      When RX Ethernet frames span multiple URB socket buffers,
      the data stream may suffer a discontinuity which will cause
      the current Ethernet frame in the netdev socket buffer
      to be incomplete. This frame needs to be discarded instead
      of appending unrelated data from the current URB socket buffer
      to the Ethernet frame in the netdev socket buffer. This avoids
      creating a corrupted Ethernet frame in the netdev socket buffer.

      A discontinuity can occur when the previous URB socket buffer
      held an incomplete Ethernet frame due to truncation or a
      URB socket buffer containing the end of the Ethernet frame
      was missing.

      Therefore, add a sanity test for when an Ethernet frame
      spans multiple URB socket buffers to check that the remaining
      bytes of the currently received Ethernet frame point to
      a good Data header 32-bit word of the next Ethernet
      frame. Upon error, reset the remaining bytes variable to
      zero and discard the current netdev socket buffer.
      Assume that the Data header is located at the start of
      the current socket buffer and attempt to process the next
      Ethernet frame from there. This avoids unnecessarily
      discarding a good URB socket buffer that contains a new
      Ethernet frame.

      asix: Simplify asix_rx_fixup_internal() netdev alloc

      The code is checking that the Ethernet frame will fit into a
      netdev allocated socket buffer within the constraints of MTU size,
      Ethernet header length plus VLAN header length.

      The original code was checking rx->remaining each loop of the while
      loop that processes multiple Ethernet frames per URB and/or Ethernet
      frames that span across URBs. rx->remaining decreases per while loop
      so there is no point in potentially checking multiple times that the
      Ethernet frame (remaining part) will fit into the netdev socket buffer.

      The modification checks that the size of the Ethernet frame will fit
      the netdev socket buffer before allocating the netdev socket buffer.
      This avoids grabbing memory and then deciding that the Ethernet frame
      is too big and then freeing the memory.

      asix: Tidy-up 32-bit header word synchronisation

      Tidy-up the Data header 32-bit word synchronisation logic in
      asix_rx_fixup_internal() by removing redundant logic tests.

      The code is looking at the following cases of the Data header
      32-bit word that is present before each Ethernet frame:

      a) all 32 bits of the Data header word are in the URB socket buffer
      b) first 16 bits of the Data header word are at the end of the URB
         socket buffer
      c) last 16 bits of the Data header word are at the start of the URB
         socket buffer eg. split_head = true

      Note that the lifetime of rx->split_head exists outside of the
      function call and is accessed per processing of each URB. Therefore,
      split_head being true acts on the next URB to be processed.

      To check for b) the offset will be 16 bits (2 bytes) from the end of
      the buffer then indicate split_head is true.
      To check for c) split_head must be true because the first 16 bits
      have been found.
      To check for a) else c)

      Note that the || logic of the old code included the state
      (skb->len - offset == sizeof(u16) && rx->split_head) which is not
      possible because the split_head cannot be true whilst checking for b).
      This is because the split_head indicates that the first 16 bits have
      been found and that is not possible whilst checking for the first 16
      bits. Therefore simplify the logic.

      asix: Rename remaining and size for clarity

      The Data header synchronisation is easier to understand
      if the variables "remaining" and "size" are renamed.

      Therefore, the lifetime of the "remaining" variable exists
      outside of asix_rx_fixup_internal() and is used to indicate
      any remaining pending bytes of the Ethernet frame that need
      to be obtained from the next socket buffer. This allows an
      Ethernet frame to span across multiple socket buffers.

      "size" is now local to asix_rx_fixup_internal() and contains
      the size read from the Data header 32-bit word.

      Add "copy_length" to hold the number of the Ethernet frame
      bytes (maybe a part of a full frame) that are to be copied
      out of the socket buffer.

      bpf, seccomp: prepare for upcoming criu support

      The current ongoing effort to dump existing cBPF seccomp filters back
      to user space requires to hold the pre-transformed instructions like
      we do in case of socket filters from sk_attach_filter() side, so they
      can be reloaded in original form at a later point in time by utilities
      such as criu.

      To prepare for this, simply extend the bpf_prog_create_from_user()
      API to hold a flag that tells whether we should store the original
      or not. Also, fanout filters could make use of that in future for
      things like diag. While fanout filters already use bpf_prog_destroy(),
      move seccomp over to them as well to handle original programs when
      present.

      That way, it can also be known that a program _is_ attached (as

      to be consulted for a dump.

      act_mirred: fix a race condition on mirred_list

      After commit 1ce87720d456 ("net: sched: make cls_u32 lockless")
      we began to release tc actions in a RCU callback. However,
      mirred action relies on RTNL lock to protect the global
      mirred_list, therefore we could have a race condition
      between RCU callback and netdevice event, which caused
      a list corruption as reported by Vinson.

      Instead of relying on RTNL lock, introduce a spinlock to
      protect this list.

      Note, in non-bind case, it is still called with RTNL lock,
      therefore should disable BH too.

      iwlwifi: mvm: add minimal multi-RXQ infrastructure

      Since the new multi-queue capability depends on a new firmware API,
      we can already add some code for it. If the new API is present, a
      new opmode ops struct is used that handles the new rx_rss method.

      For now, only restructure the RX handling to distinguish between
      the two. Future patches will convert the new infrastructure to
      actually use the new RX descriptor layout.

      Instead of relying on a hard-coded constant of a maximum of 64 API and

      always track the number of used bits in the API/capabilities. We thus
      no longer need to maintain the maximum number, and on 32-bit platforms
      even (currently) reduce the number of bits kept in memory.

      iwlwifi: mvm: rs: fix success ratio comparison in rs_get_best_rate

      success_ratio is actually 128 * SR in percentage while
      IWL_MVM_RS_SR_NO_DECREASE is 85%. Fix this by using RS_PERCENT().
      This bug caused the if branch to be always executed. This in turn
      led to always selecting a rate, following a column switch, in which
      the expected throughput would exceed the best expected current throughput.
      In some scenarios where the success ratio isn't >85% such a rate
      could be too aggressive leading us to avoid the new column.
      This has the potential of causing sub optimal performance.

      Therefore, it's pointless to send it two bits, and the API

      iwlwifi: mvm: support using multiple ACs on single HW queue

      "DQA" is shorthand for "dynamic queue allocation", with the
      idea of allocating queues per-RA/TID on-demand rather than
      using shared queues statically allocated per vif. The goal
      of this is to enable future features (like GO PM) and to
      improve performance measurements of TX traffic.

      When RA/TID streams can't be neatly sorted into different AC
      queues, DQA allows sharing queues for the same RA. This means
      that DQA allows different ACs may reach the same HW queue.

      Update the code to allow such queue sharing by having a mapping
      between the HW queue and the mac80211 queues using it (as this
      could be more than one queue).

      Upcoming hardware will have the ability to do L3 hashing for RSS,
      directing data packets (and perhaps some associated metadata and

      In this case, it makes no sense to go through the full RX dispatch
      since it's already known that only a subset of the possibilities
      can come in, requiring a new receive method. In addition this must
      know which queue the packet was received on.

      i40e: fix offload of GRE tunnels

      The driver still was not offloading TSO on GRE tunnels because
      it forgot to set the GSO_GRE flag, causing lots of retransmits.

      This fixes generic GRE traffic (like a tunnel added like below)
      whereas before it would get 1Gb/s or less, now on a 10G adapter
      it gets 8.7Gb/s.

      inet: fix race in reqsk_queue_unlink()

      reqsk_timer_handler() tests if icsk_accept_queue.listen_opt
      is NULL at its beginning.

      By the time it calls inet_csk_reqsk_queue_drop() and
      reqsk_queue_unlink(), listener might have been closed and
      inet_csk_listen_stop() had called reqsk_queue_yank_acceptq()
      which sets icsk_accept_queue.listen_opt to NULL

      We therefore need to correctly check listen_opt being NULL

      enic: do hang reset only in case of tx timeout

      The current code invokes hang reset in case of error interrupt. We should
      hang reset only in case of tx timeout. This because of the way hang reset
      is implemented in firmware. Hang reset takes more firmware resources than
      soft reset. Adaptor does not generate error interrupt in case of tx
      timeout.

      Hang reset only in case of tx timeout, in .ndo_tx_timeout. Do soft reset
      otherwise. Introduce deferred work, enic_tx_hang_reset, to do hang reset.

      iwlwifi: mvm: fix D3 CCMP TX PN assignment

      When going into/coming out of D3, the TX PN must be programmed into
      and restored from the firmware respectively. The restore was broken
      due to my previous commit to move PN assignment into the driver.
      Sending the PN to the firmware still worked since we now use the
      counter that's shared with mac80211, but accessing it through the
      mac80211 API makes no sense now.

      Fix this by reading/writing the counter directly. This actually
      simplifies the code since we don't need to round-trip through the
      key_seq structure.

      net: Pass net through ip fragmention

      This is the next installment of my work to pass struct net through the
      output path so the code does not need to guess how to figure out which
      network namespace it is in, and ultimately routes can have output
      devices in another network namespace.

      This round focuses on passing net through ip fragmentation which we seem
      to call from about everywhere.  That is the main ip output paths, the
      bridge netfilter code, and openvswitch.  This has to happend at once
      accross the tree as function pointers are involved.

      First some prep work is done, then ipv4 and ipv6 are converted and then
      temporary helper functions are removed.

      RDS: RDS-TCP perf enhancements

      A 3-part patchset that (a) improves current RDS-TCP perf
      by 2X-3X and (b) refactors earlier robustness code for
      better observability/scaling.

      Patch 1 is an enhancment of earlier robustness fixes
      that had used separate sockets for client and server endpoints to
      resolve race conditions. It is possible to have an equivalent
      solution that does not use 2 sockets. The benefit of a
      single socket solution is that it results in more predictable
      and observable behavior for the underlying TCP pipe of an
      RDS connection

      Patches 2 and 3 are simple, straightforward perf bug fixes
      that align the RDS TCP socket with other parts of the kernel stack.

      v2: fix kbuild-test-robot warnings, comments from  Sergei Shtylov

      RDS-TCP: Do not bloat sndbuf/rcvbuf in rds_tcp_tune

      Using the value of RDS_TCP_DEFAULT_BUFSIZE (128K)
      clobbers efficient use of TSO because it inflates the size_goal
      that is computed in tcp_sendmsg/tcp_sendpage and skews packet
      latency, and the default values for these parameters actually
      results in significantly better performance.

      In request-response tests using rds-stress with a packet size of
      100K with 16 threads (test parameters -q 100000 -a 256 -t16 -d16)
      between a single pair of IP addresses achieves a throughput of
      6-8 Gbps. Without this patch, throughput maxes at 2-3 Gbps under
      equivalent conditions on these platforms.

      RDS: Use a single TCP socket for both send and receive.

      Commit f711a6ae062c ("net/rds: RDS-TCP: Always create a new rds_sock
      for an incoming connection.") modified rds-tcp so that an incoming SYN
      would ignore an existing "client" TCP connection which had the local
      port set to the transient port.  The motivation for ignoring the existing
      "client" connection in f711a6ae was to avoid race conditions and an
      endless duel of reconnect attempts triggered by a restart/abort of one
      of the nodes in the TCP connection.

      However, having separate sockets for active and passive sides
      is avoidable, and the simpler model of a single TCP socket for
      both send and receives of all RDS connections associated with
      that tcp socket makes for easier observability. We avoid the race
      conditions from f711a6ae by attempting reconnects in rds_conn_shutdown
      if, and only if, the (new) c_outgoing bit is set for RDS_TRANS_TCP.
      The c_outgoing bit is initialized in __rds_conn_create().

      A side-effect of re-using the client rds_connection for an incoming
      SYN is the potential of encountering duelling SYNs, i.e., we
      have an outgoing RDS_CONN_CONNECTING socket when we get the incoming
      SYN. The logic to arbitrate this criss-crossing SYN exchange in
      rds_tcp_accept_one() has been modified to emulate the BGP state
      machine: the smaller IP address should back off from the connection 
attempt.

      ====================
      net: assorted y2038 changes

      This is a set of changes for network drivers and core code to
      get rid of the use of time_t and derived data structures.

      I have a longer set of patches that enables me to build kernels
      with the time_t definition removed completely as a help to find
      y2038 overflow issues. This is the subset for networking that
      contains all code that has a reasonable way of fixing at the
      moment and that is either commonly used (in one of the defconfigs)
      or that blocks building a whole subsystem.

      Most of the patches in this series should be noncontroversial,
      but the last two that I marked [RFC] are a bit tricky and
      need input from people that are more familiar with the code than
      I am. All 12 patches are independent of one another and can
      be applied in any order, so feel free to pick all that look
      good.

      net: sctp: avoid incorrect time_t use

      We want to avoid using time_t in the kernel because of the y2038
      overflow problem. The use in sctp is not for storing seconds at
      all, but instead uses microseconds and is passed as 32-bit
      on all machines.

      This patch changes the type to u32, which better fits the use.

      ipv6: use ktime_t for internal timestamps

      The ipv6 mip6 implementation is one of only a few users of the
      skb_get_timestamp() function in the kernel, which is both unsafe
      on 32-bit architectures because of the 2038 overflow, and slightly
      less efficient than the skb_get_ktime() based approach.

      This converts the function call and the mip6_report_rate_limiter
      structure that stores the time stamp, eliminating all uses of
      timeval in the ipv6 code.

      nfnetlink: use y2038 safe timestamp

      The __build_packet_message function fills a nfulnl_msg_packet_timestamp
      structure that uses 64-bit seconds and is therefore y2038 safe, but
      it uses an intermediate 'struct timespec' which is not.

      This trivially changes the code to use 'struct timespec64' instead,
      to correct the result on 32-bit architectures.

      atm: remove 'struct zatm_t_hist'

      The zatm_t_hist structure is not used anywhere in the kernel, but is
      exported to user space. As we are trying to eliminate uses of time_t
      in the kernel for y2038 compatibility, the current definition triggers
      checking tools because it contains 'struct timeval'.

      As pointed out by Chas Williams, the only user of this structure was
      the ZATM_GETHIST ioctl command that has been removed a long time ago,
      and we can remove the structure as well without breaking any user
      space.

      mac80211: use ktime_get_seconds

      The mac80211 code uses ktime_get_ts to measure the connected time.
      As this uses monotonic time, it is y2038 safe on 32-bit systems,
      but we still want to deprecate the use of 'timespec' because most
      other users are broken.

      This changes the code to use ktime_get_seconds() instead, which
      avoids the timespec structure and is slightly more efficient.

      mwifiex: avoid gettimeofday in ba_threshold setting

      mwifiex_get_random_ba_threshold() uses a complex homegrown implementation
      to generate a pseudo-random number from the current time as returned
      from do_gettimeofday().

      This currently requires two 32-bit divisions plus a couple of other
      computations that are eventually discarded as only eight bits of
      the microsecond portion are used at all.

      We could replace this with a call to get_random_bytes(), but that
      might drain the entropy pool too fast if this is called for each
      packet.

      Instead, this patch converts it to use ktime_get_ns(), which is a
      bit faster than do_gettimeofday(), and then uses a similar algorithm
      as before, but in a way that takes both the nanosecond and second
      portion into account for slightly-more-but-still-not-very-random
      pseudorandom number.

      mwifiex: use ktime_get_real for timestamping

      The mwifiex_11n_aggregate_pkt() function creates a ktime_t from
      a timeval returned by do_gettimeofday, which is slow and causes
      an overflow in 2038 on 32-bit architectures.

      This solves both problems by using the appropriate ktime_get_real()
      function.

      net: igb: avoid using timespec

      We want to deprecate the use of 'struct timespec' on 32-bit
      architectures, as it is will overflow in 2038. The igb

      Because of hardware limitations, there is still an overflow

      net: fec: avoid timespec use

      The fec_ptp_enable_pps uses an open-coded implementation of 
ns_to_timespec,
      which will be removed eventually as it is not y2038-safe on 32-bit
      architectures. Two more instances of the same code in this file were
      already converted to use the safe ns_to_timespec64 in commit 6630514fcee
      ("ptp: fec: use helpers for converting ns to timespec"), this changes
      the last one as well.

      The seconds portion here is actually unused and we could just remove the
      timespec variable, but using ns_to_timespec64 can still be better as the
      implementation can be hand-optimized in the future.

      ppp: don't override sk->sk_state in pppoe_flush_dev()

      Since commit 2b018d57ff18 ("pppoe: drop PPPOX_ZOMBIEs in pppoe_release"),
      pppoe_release() calls dev_put(po->pppoe_dev) if sk is in the

      PPPOX_ZOMBIE _and_ reset po->pppoe_dev to NULL. This leads to the

      Peter Nørlund says:

      ====================
      ipv4: Hash-based multipath routing

      When the routing cache was removed in 3.6, the IPv4 multipath algorithm 
changed
      from more or less being destination-based into being quasi-random 
per-packet
      scheduling. This increases the risk of out-of-order packets and makes it
      impossible to use multipath together with anycast services.

      This patch series replaces the old implementation with flow-based load
      balancing based on a hash over the source and destination addresses.

      Distribution of the hash is done with thresholds as described in RFC 2992.
      This reduces the disruption when a path is added/remove when having more 
than
      two paths.

      To futher the chance of successful usage in conjuction with anycast, ICMP
      error packets are hashed over the inner IP addresses. This ensures that 
PMTU
      will work together with anycast or load-balancers such as IPVS.

      Port numbers are not considered since fragments could cause problems with
      anycast and IPVS. Relying on the DF-flag for TCP packets is also 
insufficient,
      since ICMP inspection effectively extracts information from the opposite
      flow which might have a different state of the DF-flag. This is also why 
the
      RSS hash is not used. These are typically based on the NDIS RSS spec which
      mandates TCP support.

      Measurements of the additional overhead of a two-path multipath
      (p_mkroute_input excl. __mkroute_input) on a Xeon X3550 (4 cores, 
2.66GHz):

      Original per-packet: ~394 cycles/packet
      L3 hash:              ~76 cycles/packet

      Changes in v5:
      - Fixed compilation error

      Changes in v4:
      - Functions take hash directly instead of func ptr
      - Added inline hash function
      - Added dummy macros to minimize ifdefs
      - Use upper 31 bits of hash instead of lower

      Changes in v3:
      - Multipath algorithm is no longer configurable (always L3)
      - Added random seed to hash
      - Moved ICMP inspection to isolated function
      - Ignore source quench packets (deprecated as per RFC 6633)

      Changes in v2:
      - Replaced 8-bit xor hash with 31-bit jenkins hash
      - Don't scale weights (since 31-bit)
      - Avoided unnecesary renaming of variables
      - Rely on DF-bit instead of fragment offset when checking for 
fragmentation
      - upper_bound is now inclusive to avoid overflow
      - Use a callback to postpone extracting flow information until necessary
      - Skipped ICMP inspection entirely with L4 hashing
      - Handle newly added sysctl ignore_routes_with_linkdown

      tcp: avoid two atomic ops for syncookies

      inet_reqsk_alloc() is used to allocate a temporary request
      in order to generate a SYNACK with a cookie. Then later,

      These paths already took a reference on listener refcount,

      tcp: fix fastopen races vs lockless listener

      There are multiple races that need fixes :

      1) skb_get() + queue skb + kfree_skb() is racy

      An accept() can be done on another cpu, data consumed immediately.
      tcp_recvmsg() uses __kfree_skb() as it is assumed all skb found in
      socket receive queue are private.

      Then the kfree_skb() in tcp_rcv_state_process() uses an already freed skb

      2) tcp_reqsk_record_syn() needs to be done before tcp_try_fastopen()
      for the same reasons.

      3) We want to send the SYNACK before queueing child into accept queue,
      otherwise we might reintroduce the ooo issue fixed in

      MIPS: UAPI: Ignore __arch_swab{16,32,64} when using MIPS16

      Some GCC versions (e.g. 4.8.3) can incorrectly inline a function with
      MIPS32 instructions into another function with MIPS16 code [1], causing
      the assembler to genereate incorrect binary code or fail right away
      complaining about unrecognized opcode.

      In the case of __arch_swab{16,32}, when inlined by the compiler with
      flags `-mips32r2 -mips16 -Os', the assembler can fail with the following
      error.

          {standard input}:79: Error: unrecognized opcode `wsbh $2,$2'

      For performance concerns and to workaround the issue already existing in
      older compilers, just ignore these 2 functions when compiling with
      mips16 enabled.

      For at least GCC 4.8.3, adding nomips16 function attribute still cannot
      prevent it from being inlined in mips16 context.  So revert it first in
      preparation for a better workaround.

      Additionally, the formula is actually wrong - if the calculation

      The commit 7bee8b08c428 allows the Read Verbose Config Info to fail
      gracefully and not cause the controller setup to abort. It seems the
      reason that command failed in the first place was the missing HCI Reset
      to bring the controller in full Bluetooth mode.

      Apple Bluetooth controllers start out in HID mode and when in that mode
      the Read Verbose Config Info command is not allowed. Sending HCI Reset
      switches the controller into full HCI mode.

      This set completes the bridge device's netlink support and makes it

      longer line warnings about the br_get_size() ifla comments but I think we
      should have them to know what has been accounted for. I have used the 
sysfs
      interface as a guide of what and how to set. As usual I'll send the
      corresponding iproute2 patches later.
      The bridge port's netlink interface will be completed after this set gets
      applied in some form.

      When I did the conversion to rhashtable I missed the required locking of

      which is called:
      br_ifinfo_notify() -> br_nlmsg_size() -> br_get_link_af_size_filtered()
      and the notifications can be sent without holding rtnl. Before this
      conversion the function relied on using rcu and since we already use rcu 
to
      destroy the vlans, we can simply migrate the list to use the rcu helpers.

      netfilter: nfnetlink_queue: get rid of nfnetlink_queue_ct.c

      The original intention was to avoid dependencies between nfnetlink_queue 
and
      conntrack without ifdef pollution. However, we can achieve this by moving 
the
      conntrack dependent code into ctnetlink and keep some glue code to access 
the
      nfq_ct indirection from nfqueue.

      After this patch, the nfq_ct indirection is always compiled in the 
netfilter
      core to avoid polluting nfqueue with ifdefs. Thus, if nf_conntrack is not
      compiled this results in only 8-bytes of memory waste in x86_64.

      This patch also adds ctnetlink_nfqueue_seqadj() to avoid that the nf_conn
      structure layout if exposed to nf_queue, which creates another dependency 
with
      nf_conntrack at compilation time.

      tty: fix data race on tty_buffer.commit

      Race on buffer data happens when newly committed data is
      picked up by an old flush work in the following scenario:
      __tty_buffer_request_room does a plain write of tail->commit,
      no barriers were executed before that.
      At this point flush_to_ldisc reads this new value of commit,
      and reads buffer data, no barriers in between.
      The committed buffer data is not necessary visible to flush_to_ldisc.

      Similar bug happens when tty_schedule_flip commits data.

      Update commit with smp_store_release and read commit with
      smp_load_acquire, as it is commit that signals data readiness.
      This is orthogonal to the existing synchronization on tty_buffer.next,
      which is required to not dismiss a buffer with unconsumed data.

      The data race was found with KernelThreadSanitizer (KTSAN).

      tty: fix data race in tty_buffer_flush

      tty_buffer_flush frees not acquired buffers.
      As the result, for example, read of b->size in tty_buffer_free
      can return garbage value which will lead to a huge buffer
      hanging in the freelist. This is just the benignest
      manifestation of freeing of a not acquired object.
      If the object is passed to kfree, heap can be corrupted.

      Acquire visibility over the buffer before freeing it.

      flush_to_ldisc reads port->itty and checks that it is not NULL,
      concurrently release_tty sets port->itty to NULL. It is possible
      that flush_to_ldisc loads port->itty once, ensures that it is
      not NULL, but then reloads it again and uses. The second load
      can already return NULL, which will cause a crash.

      tty: fix stall caused by missing memory barrier in drivers/tty/n_tty.c

      My colleague ran into a program stall on a x86_64 server, where
      n_tty_read() was waiting for data even if there was data in the buffer
      in the pty.  kernel stack for the stuck process looks like below.
       #0 [ffff88303d107b58] __schedule at ffffffff815c4b20
       #1 [ffff88303d107bd0] schedule at ffffffff815c513e

       #9 [ffff88303d107f50] entry_SYSCALL_64_fastpath at ffffffff815c86d7

      There seems to be two problems causing this issue.

      First, in drivers/tty/n_tty.c, __receive_buf() stores the data and
      updates ldata->commit_head using smp_store_release() and then checks
      the wait queue using waitqueue_active().  However, since there is no
      memory barrier, __receive_buf() could return without calling
      wake_up_interactive_poll(), and at the same time, n_tty_read() could
      start to wait in wait_woken() as in the following chart.

              __receive_buf()                         n_tty_read()
      ------------------------------------------------------------------------
      if (waitqueue_active(&tty->read_wait))
      /* Memory operations issued after the
         RELEASE may be completed before the
         RELEASE operation has completed */
                                              add_wait_queue(&tty->read_wait, 
&wait);
                                              ...
                                              if (!input_available_p(tty, 0)) {
      smp_store_release(&ldata->commit_head,
                        ldata->read_head);
                                              ...
                                              timeout = wait_woken(&wait,
                                                TASK_INTERRUPTIBLE, timeout);
      ------------------------------------------------------------------------

      The second problem is that n_tty_read() also lacks a memory barrier
      call and could also cause __receive_buf() to return without calling
      wake_up_interactive_poll(), and n_tty_read() to wait in wait_woken()
      as in the chart below.

              __receive_buf()                         n_tty_read()
      ------------------------------------------------------------------------
                                              spin_lock_irqsave(&q->lock, 
flags);
                                              /* from add_wait_queue() */
                                              ...
                                              if (!input_available_p(tty, 0)) {
                                              /* Memory operations issued after

before the
                                                 RELEASE operation has 
completed */
      smp_store_release(&ldata->commit_head,
                        ldata->read_head);
      if (waitqueue_active(&tty->read_wait))
                                              __add_wait_queue(q, wait);
                                              
spin_unlock_irqrestore(&q->lock,flags);
                                              /* from add_wait_queue() */
                                              ...
                                              timeout = wait_woken(&wait,
                                                TASK_INTERRUPTIBLE, timeout);
      ------------------------------------------------------------------------

      There are also other places in drivers/tty/n_tty.c which have similar
      calls to waitqueue_active(), so instead of adding many memory barrier
      calls, this patch simply removes the call to waitqueue_active(),
      leaving just wake_up*() behind.

      This fixes both problems because, even though the memory access before
      or after the spinlocks in both wake_up*() and add_wait_queue() can
      sneak into the critical section, it cannot go past it and the critical
      section assures that they will be serialized (please see "INTER-CPU
      ACQUIRING BARRIER EFFECTS" in Documentation/memory-barriers.txt for a
      better explanation).  Moreover, the resulting code is much simpler.

      Latency measurement using a ping-pong test over a pty doesn't show any
      visible performance drop.

      If atmel_init_gpios fails the port has already been marked as busy (in

      tty: don't leak cdev in tty_cdev_add()

      Commit a3a10ce3429e ("Avoid usb reset crashes by making tty_io cdevs truly
      dynamic") which mixes using cdev_alloc() and cdev_init() is problematic.
      Subsequent call to cdev_init() after cdev_alloc() sets kobj release method
      from cdev_dynamic_release() to cdev_default_release() and thus makes it
      impossible to free allocated cdev.

      This patch also consolidates error path of cdev_add() as cdev can also 
leak
      here if things went wrong.

      Merge branch 'strscpy' of 
git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile

      Pull strscpy string copy function implementation from Chris Metcalf.

      Chris sent this during the merge window, but I waffled back and forth on
      the pull request, which is why it's going in only now.

      The new "strscpy()" function is definitely easier to use and more secure
      than either strncpy() or strlcpy(), both of which are horrible nasty
      interfaces that have serious and irredeemable problems.

      strncpy() has a useless return value, and doesn't NUL-terminate an
      overlong result.  To make matters worse, it pads a short result with
      zeroes, which is a performance disaster if you have big buffers.

      strlcpy(), by contrast, is a mis-designed "fix" for strlcpy(), lacking
      the insane NUL padding, but having a differently broken return value
      which returns the original length of the source string.  Which means
      that it will read characters past the count from the source buffer, and
      you have to trust the source to be properly terminated.  It also makes
      error handling fragile, since the test for overflow is unnecessarily
      subtle.

      strscpy() avoids both these problems, guaranteeing the NUL termination
      (but not excessive padding) if the destination size wasn't zero, and
      making the overflow condition very obvious by returning -E2BIG.  It also
      doesn't read past the size of the source, and can thus be used for
      untrusted source data too.

      So why did I waffle about this for so long?

      Every time we introduce a new-and-improved interface, people start doing
      these interminable series of trivial conversion patches.

      And every time that happens, somebody does some silly mistake, and the
      conversion patch to the improved interface actually makes things worse.
      Because the patch is mindnumbing and trivial, nobody has the attention
      span to look at it carefully, and it's usually done over large swatches
      of source code which means that not every conversion gets tested.

      So I'm pulling the strscpy() support because it *is* a better interface.
      But I will refuse to pull mindless conversion patches.  Use this in
      places where it makes sense, but don't do trivial patches to fix things
      that aren't actually known to be broken.

      MIPS: scall: Always run the seccomp syscall filters

      The MIPS syscall handler code used to return -ENOSYS on invalid
      syscalls. Whilst this is expected, it caused problems for seccomp
      filters because the said filters never had the change to run since
      the code returned -ENOSYS before triggering them. This caused
      problems on the chromium testsuite for filters looking for invalid
      syscalls. This has now changed and the seccomp filters are always
      run even if the syscall is invalid. We return -ENOSYS once we
      return from the seccomp filters. Moreover, similar codepaths have
      been merged in the process which simplifies somewhat the overall
      syscall code.

      usb: Add device quirk for Logitech PTZ cameras

      Add a device quirk for the Logitech PTZ Pro Camera and its sibling the
      ConferenceCam CC3000e Camera.
      This fixes the failed camera enumeration on some boot, particularly on
      machines with fast CPU.

      Tested by connecting a Logitech PTZ Pro Camera to a machine with a
      Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles
      while recording the kernel logs and taking camera picture after each boot.
      Before the patch, more than 7% of the boots show some enumeration transfer
      failures and in a few of them, the kernel is giving up before actually
      enumerating the webcam. After the patch, the enumeration has been correct
      on every reboot.

      i40evf: don't blow away MAC address

      Under certain circumstances, we can get an extra VF_RESOURCES message
      from the PF driver at runtime. When this happens, we need to parse it
      because our VSI may have changed out from underneath us, and that will
      affect our relationship with the PF driver.

      However, parsing the resources message also blows away our current MAC
      address in the hardware struct, usually with all zeros. When this
      happens, the next time the interface is opened, it will have no MAC
      address and will a) not work and b) complain.

      Fix this issue by restoring the current MAC address from the netdev
      struct after we parse the resource message.

      tcp/dccp: add SLAB_DESTROY_BY_RCU flag for request sockets

      Before letting request sockets being put in TCP/DCCP regular
      ehash table, we need to add either :

      - SLAB_DESTROY_BY_RCU flag to their kmem_cache
      - add RCU grace period before freeing them.

      Since we carefully respected the SLAB_DESTROY_BY_RCU protocol
      like ESTABLISH and TIMEWAIT sockets, use it here.

      req_prot_init() being only used by TCP and DCCP, I did not add
      a new slab_flags into their rsk_prot, but reuse prot->slab_flags

      Since all reqsk_alloc() users are correctly dealing with a failure,
      add the __GFP_NOWARN flag to avoid traces under pressure.

      Bluetooth: btintel: Add iBT register access over HCI support

      Add regmap ibt to support Intel Bluetooth silicon register access
      over HCI. Intel BT/FM combo chip allows to read/write some registers
      (e.g. FM registers) via its HCI interface.

      Read/Write operations are performed via a HCI transaction composed of
      a HCI command (host->controller) followed by a HCI command complete
      event (controller->host). Read/Write Command opcodes can be specified
      to the regmap init function.
      We define data formats which are intel/vendor specific.

      Register Read/Write HCI command payload (Host):
      Field: | REG ADDR | MODE | DATA_LEN | DATA... |
      size:  |   32b    |  8b  |    8b    |  8b*    |

      Register Read HCI command complete event payload (Controller):
      Field: | CMD STATUS | REG ADDR | DATA... |
      size:  |     8b     |   32b    |  8b*    |

      Register Write HCI command complete event payload (Controller):
      Field: | CMD_STATUS |
      size:  |     8b     |

      Since this payload is HCI encapsulated, Little Endian byte order is
      used.

      Write/Read Example:

      If we write 0x0000002a at address 0x00008c04, with opcode_write 0xfc5d,
      The resulting transaction is (btmon trace):

      < HCI Command (0x3f|0x005d) plen 10 [hci0]
              04 8c 00 00 02 04 2a 00 00 00
      > HCI Event (0x0e) plen 4
            Unknown (0x3f|0x005d) ncmd 1
              00

      Then, if we read the same register with opcode_read 0xfc5e:

      < HCI Command (0x3f|0x005e) plen 6 [hci0]
              04 8c 00 00 02 04
      > HCI Event (0x0e) plen 12 [hci0]
            Unknown (0x3f|0x005e) ncmd 1
              00 04 8c 00 00 2a 00 00 00

      ARM: 8439/1: Fix backtrace generation when IPI is masked

      Currently on ARM when <SysRq-L> is triggered from an interrupt handler
      (e.g. a SysRq issued using UART or kbd) the main CPU will wedge for ten
      seconds with interrupts masked before issuing a backtrace for every CPU
      except itself.

      The new backtrace code introduced by commit 96f0e00378d4 ("ARM: add
      basic support for on-demand backtrace of other CPUs") does not work
      correctly when run from an interrupt handler because IPI_CPU_BACKTRACE
      is used to generate the backtrace on all CPUs but cannot preempt the
      current calling context.

      This can be fixed by detecting that the calling context cannot be
      preempted and issuing the backtrace directly in this case. Issuing
      directly leaves us without any pt_regs to pass to nmi_cpu_backtrace()
      so we also modify the generic code to call dump_stack() when its
      argument is NULL.

      ARM: 8428/1: kgdb: Fix registers on sleeping tasks

      Dumping registers from other sleeping tasks in KGDB was totally
      failing for me.  All registers were reported as 0 in many cases.

      The code was using task_pt_regs(task) to try to get other thread
      registers.  This doesn't appear to be the right place to look.  From
      my tests, I saw non-zero values in this structure when we were looking
      at a kernel thread that had a userspace task associated with it, but
      it contained the register values from the userspace task.  So even in
      the cases where registers weren't reported as 0 we were still not
      showing the right thing.

      Instead of using task_pt_regs(task) let's use task_thread_info(task).
      This is the same place that is referred to when doing a dump of all
      sleeping task stacks (kdb_show_stack() -> show_stack() ->
      dump_backtrace() -> unwind_backtrace() -> thread_saved_sp()).

      As further evidence that this is the right thing to do, you can find
      the following comment in "gdbstub.c" right before it calls
      sleeping_thread_to_gdb_regs():
        Pull stuff saved during switch_to; nothing else is accessible (or
        even particularly relevant).  This should be enough for a stack
        trace.
      ...and if you look at switch_to() it only saves r4-r11, sp and lr.
      Those are the same registers that I'm getting out of the
      task_thread_info().

      With this change you can use "info thread" to see all tasks in the
      kernel and you can switch to other tasks and examine them in gdb.

      ARM: remove user cmpxchg syscall

      Mark Brand reports that a NEEDS_SYSCALL_FOR_CMPXCHG enabled kernel would
      open a security hole in the ghost syscall used to implement cmpxchg, as
      it fails to validate the user pointer.

      However, in order for this option to be enabled, you'd need to be
      building a pre-ARMv6 kernel with SMP support.  There is only one system
      known which fits that, which is an early ARM SMP FPGA implementation
      based on the ARM926T.

      In any case, the Kconfig does not allow SMP to be enabled for pre-ARMv6
      systems.

      Moreover, even if NEEDS_SYSCALL_FOR_CMPXCHG were to be enabled, the
      kernel would not build as __ARM_NR_cmpxchg64 is not defined.

      The simple answer is to remove the buggy code.

      This reverts commit 904464b91eca8c665acea033489225af02eeb75a.

      We can safely boot with nosmp and the warning won't show up.

      The other side benefit of this patch is that TWD has a chance
      to probe on single-core A9 systems such as AM437x which sport
      TWD.

      While at that, also drop SMP dependency from TWD's Kconfig entry.

      Intel Wired LAN Driver Updates 2015-09-30

      This series contains updates to i40e and i40evf only.

      Vasily Averin provides a couple of rtnl lock/unlock fixes for both i40e
      and i40evf.

      Shannon provides several updates and fixes, first fixes up a type clash
      in i40e_aq_rc_to_posix(), where the error codes are signed values, so we
      need to treat them as such.  Then fixes up a padding issue where an
      extra byte is added in i40e_aqc_get_cee_dcb_cfg_v1_resp to directly
      acknowledge the padding.  Updated i40e to keep debugfs register read
      and writes from accessing outside of the io-remapped space.  Added
      support and device id for another 20 GbE device.

      Jesse fixes the transmit hand workaround code for ARM that was causing
      Tx hangs to still occur occasionally when there really was no hang.  Then
      fixed the receive dropped counter to show up in netstat interface.
      Refactor the interrupt enable function since it was always making the
      caller add the base_vector from the VSI struct which is already passed
      to the function.  Fix kbuild warnings found in 0day build infrastructure
      by adding a harmless cast to a dev_info(), also fix 32 bit build
      warnings found by sparse.

      Greg fixed a configuration error that results if a port VLAN is set
      for a VF before the VF driver is loaded, so that when the VF driver is
      loaded the port VLAN is ignored.

      Mitch fixes the use of QOS field consistently in
      i40e_ndo_set_vf_port_vlan().  Modified the init timing of the driver
      to increase stability on load/unload and SR-IOV enable/disable cycles.

      Anjali updates i40e to not collect VEB stats if they are disabled in the
      hardware for performance reasons.

      ravb: Add support for r8a7795 SoC

      This patch supports the r8a7795 SoC by:
      - Using two interrupts
        + One for E-MAC
        + One for everything else
        + Both can be handled by the existing common interrupt handler, which
          affords a simpler update to support the new SoC. In future some
          consideration may be given to implementing multiple interrupt handlers
      - Limiting the phy speed to 100Mbit/s for the new SoC;
        at this time it is not clear how this restriction may be lifted
        but I hope it will be possible as more information comes to light

      ravb: Document binding for r8a7795 SoC

      This patch updates the ravb binding to support the r8a7795 SoC by:
      - Adding a compat string for the new hardware
      - Adding 25 named interrupts to binding for the new SoC;
        older SoCs continue to use a single multiplexed interrupt

      The example is also updated to reflect the r8a7795 as this is the
      more complex case.

      Based on work by Kazuya Mizuguchi and others.

      phylib: Add phy_set_max_speed helper

      Add a helper to allow ethernet drivers to limit the speed of a phy
      (that they are attached to).

      This mainly involves factoring out the business-end of
      of_set_phy_supported() and exporting a new symbol.

      This code seems to be open coded in several places, in several different
      variants.

      It is is envisaged that this will be used in situations where setting the
      "max-speed" property in DT is not appropriate, e.g. because the maximum
      speed is not a property of the phy hardware.

      sched, bpf: add helper for retrieving routing realms

      Using routing realms as part of the classifier is quite useful, it
      can be viewed as a tag for one or multiple routing entries (think of
      an analogy to net_cls cgroup for processes), set by user space routing
      daemons or via iproute2 as an indicator for traffic classifiers and
      later on processed in the eBPF program.

      Unlike actions, the classifier can inspect device flags and enable
      netif_keep_dst() if necessary. tc actions don't have that possibility,
      but in case people know what they are doing, it can be used from there
      as well (e.g. via devs that must keep dsts by design anyway).

      If a realm is set, the handler returns the non-zero realm. User space
      can set the full 32bit realm for the dst.

      ebpf: migrate bpf_prog's flags to bitfield

      As we need to add further flags to the bpf_prog structure, lets migrate
      both bools to a bitfield representation. The size of the base structure
      (excluding insns) remains unchanged at 40 bytes.

      Add also tags for the kmemchecker, so that it doesn't throw false
      positives. Even in case gcc would generate suboptimal code, it's not
      being accessed in performance critical paths.

      ====================
      tcp/dccp: lockless listener

      TCP listener refactoring : this is becoming interesting !

      This patch series takes the steps to use normal TCP/DCCP ehash
      table to store SYN_RECV requests, instead of the private per-listener
      hash table we had until now.

      SYNACK skb are now attached to their syn_recv request socket,
      so that we no longer heavily modify listener sk_wmem_alloc.

      listener lock is no longer held in fast path, including
      SYNCOOKIE mode.

      During my tests, my server was able to process 3,500,000
      SYN packets per second on one listener and still had available
      cpu cycles.

      That is about 2 to 3 order of magnitude what we had with older kernels.

      This effort started two years ago and I am pleased to reach expectations.

      We'll probably extend SO_REUSEPORT to add proper cpu/numa affinities,
      so that heavy duty TCP servers can get proper siloing thanks to 
multi-queues
      NIC.

      Next bottleneck is the refcount taken on listener,
      that could be avoided if we remove SLAB_DESTROY_BY_RCU
      strict semantic for listeners, and use regular RCU.

      tcp: attach SYNACK messages to request sockets instead of listener

      If a listen backlog is very big (to avoid syncookies), then
      the listener sk->sk_wmem_alloc is the main source of false
      sharing, as we need to touch it twice per SYNACK re-transmit
      and TX completion.

      (One SYN packet takes listener lock once, but up to 6 SYNACK
      are generated)

      By attaching the skb to the request socket, we remove this
      source of contention.

      Tested:

       listen(fd, 10485760); // single listener (no SO_REUSEPORT)
       16 RX/TX queue NIC
       Sustain a SYNFLOOD attack of ~320,000 SYN per second,
       Sending ~1,400,000 SYNACK per second.

      tcp/dccp: install syn_recv requests into ehash table

      In this patch, we insert request sockets into TCP/DCCP
      regular ehash table (where ESTABLISHED and TIMEWAIT sockets
      are) instead of using the per listener hash table.

      ACK packets find SYN_RECV pseudo sockets without having
      to find and lock the listener.

      In nominal conditions, this halves pressure on listener lock.

      Note that this will allow for SO_REUSEPORT refinements,
      so that we can select a listener using cpu/numa affinities instead
      of the prior 'consistent hash', since only SYN packets will
      apply this selection logic.

      We will shrink listen_sock in the following patch to ease
      code review.

      rtlwifi: rtl8821ae: Fix system lockups on boot

      In commit 1277fa2ab2f9 ("rtlwifi: Remove the clear interrupt routine from 
all
      drivers"), the code that cleared all interrupt enable bits before setting 
them
      was removed for all PCI drivers. This fixed an issue that caused TX to be
      blocked for 3-5 seconds. On some RTL8821AE units, this change causes soft
      lockups to occur on boot. For that reason, the portion of the earlier 
commit
      that applied to rtl8821ae is reverted. Kernels 4.1 and newer are affected.

      See http://marc.info/?l=linux-wireless&m=144373370103285&w=2 and
      https://bugzilla.opensuse.org/show_bug.cgi?id=944978 for two cases where
      this regression affected user systems. Note that this bug does not appear 
on
      any of the developer's setups. For those users whose systems are affected
      by the TX blockage, but do not lock up on boot, a module parameter is 
added
      to disable the interrupt clear

      NFC: nci: Use __nci_request for exported routines

      Since we do not know in which context drivers will call these
      routines, they should use the unlocked version of nci_request,
      i.e. __nci_request.
      It is up to drivers to know/decide if they need to take the
      req_lock mutex before calling those routines. When being called
      from the NCI setup routine there is no need to do so as ops->setup
      is called under req_lock.

      This patch fixes one cases where abs() was being used with 64-bit
      nanosecond values, where the result may be capped at 32-bits.

      This potentially could cause watchdog false negatives on 32-bit

      gpio: omap: convert to use generic irq handler

      This patch converts TI OMAP GPIO driver to use generic irq handler
      instead of chained IRQ handler. This way OMAP GPIO driver will be
      compatible with RT kernel where it will be forced thread IRQ handler
      while in non-RT kernel it still will be executed in HW IRQ context.
      As part of this change the IRQ wakeup configuration is applied to
      GPIO Bank IRQ as it now will be under control of IRQ PM Core during
      suspend.

      There are also additional benefits:
       - on-RT kernel there will be no complains any more about PM runtime usage
         in atomic context  "BUG: sleeping function called from invalid 
context";
       - GPIO bank IRQs will appear in /proc/interrupts and its usage statistic
          will be  visible;
       - GPIO bank IRQs could be configured through IRQ proc_fs interface and,
         as result, could be a part of IRQ balancing process if needed;
       - GPIO bank IRQs will be under control of IRQ PM Core during
         suspend to RAM.

      Disadvantage:
       - additional runtime overhed as call chain till
         omap_gpio_irq_handler() will be longer now
       - necessity to use wa_lock in omap_gpio_irq_handler() to W/A warning
         in handle_irq_event_percpu()
         WARNING: CPU: 1 PID: 35 at kernel/irq/handle.c:149 
handle_irq_event_percpu+0x51c/0x638()

      This patch doesn't fully follows recommendations provided by Sebastian
      Andrzej Siewior [1], because It's required to go through and check all
      GPIO IRQ pin states as fast as possible and pass control to 
handle_level_irq
      or handle_edge_irq. handle_level_irq or handle_edge_irq will perform 
actions
      specific for IRQ triggering type and wakeup corresponding registered
      threaded IRQ handler (at least it's expected to be threaded).
      IRQs can be lost if handle_nested_irq() will be used, because excecution
      time of some pin specific GPIO IRQ handler can be very significant and
      require accessing ext. devices (I2C).

      Idea of such kind reworking was also discussed in [2].

      perf stat: Reduce min --interval-print to 10ms

      The --interval-print parameter was limited to 100ms. However, for
      example, 10ms is required to do sophisticated bandwidth analysis using
      uncore events.

      The test shows that the overhead of the system-wide uncore monitoring
      with 10ms interval is only ~2%. So this patch reduces the minimal
      interval-print allowd to 10ms.

      But 10ms may not work well for all cases. For example, when the
      cpus/threads number is very large, for system-wide core event monitoring
      the overhead could be high.

      To handle this issue, a warning will be displayed when the
      interval-print is set between 10ms to 100ms. So users can make a
      decision according to their specific cases.

       # perf stat -e uncore_imc_1/cas_count_read/ -a --interval-print 10 -- 
sleep 1

       print interval < 100ms. The overhead percentage could be high in some
       cases. Please proceed with caution.

      nfs4: reset states to use open_stateid when returning delegation 
voluntarily

      When the client goes to return a delegation, it should always update any
      nfs4_state currently set up to use that delegation stateid to instead
      use the open stateid. It already does do this in some cases,
      particularly in the state recovery code, but not currently when the
      delegation is voluntarily returned (e.g. in advance of a RENAME).  This
      causes the client to try to continue using the delegation stateid after
      the DELEGRETURN, e.g. in LAYOUTGET.

      Set the nfs4_state back to using the open stateid in
      nfs4_open_delegation_recall, just before clearing the
      NFS_DELEGATED_STATE bit.

      NFSv4: Don't try to reclaim unused state owners

      Currently, we don't test if the state owner is in use before we try to
      recover it. The problem is that if the refcount is zero, then the
      state owner will be waiting on the lru list for garbage collection.
      The expectation in that case is that if you bump the refcount, then
      you must also remove the state owner from the lru list. Otherwise
      the call to nfs4_put_state_owner will corrupt that list by trying
      to add our state owner a second time.

      Avoid the whole problem by just skipping state owners that hold no
      state.

      NFS: Fix a write performance regression

      If all other conditions in nfs_can_extend_write() are met, and there
      are no locks, then we should be able to assume close-to-open semantics
      and the ability to extend our write to cover the whole page.

      With this patch, the xfstests generic/074 test completes in 242s instead
      of >1400s on my test rig.

      NFS: Fix up page writeback accounting

      Currently, we are crediting all the calls to nfs_writepages_callback()
      (i.e. the nfs_writepages() callback) to nfs_writepage(). Aside from
      being inconsistent with the behaviour of the equivalent readpage/readpages
      accounting, this also means that we cannot distinguish between bulk writes
      and single page writebacks (which confuses the 'nfsiostat -p' tool).

      perf record: Change 'record.samples' type to unsigned long long

      When run "perf record -e", the number of samples showed up is wrong on 
some
      32 bit systems, i.e. powerpc and arm.

      For example, run the below commands on 32 bit powerpc:

        perf probe -x /lib/libc.so.6 malloc
        perf record -e probe_libc:malloc -a ls perf.data
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.036 MB perf.data 
(13829241621624967218 samples) ]

      Actually, "perf script" just shows 21 samples. The number of samples is 
also
      absurd since samples is long type, but it is printed as PRIu64.

      Build test ran on x86-64, x86, aarch64, arm, mips, ppc and ppc64.

      perf probe: Allow probing on kmodules without dwarf

      Allow probing on kernel modules when 'perf' is built without debuginfo
      support.

      Currently perf-probe --module requires linking with libdw, but this
      doesn't make sense.

      E.g.
        ----
        # make NO_DWARF=1
        # ./perf probe -m pcspkr pcspkr_event%return
          Error: unknown switch `m'
        ----

      With this patch
        ----
        # ./perf probe -m pcspkr pcspkr_event%return
        Added new event:
          probe:pcspkr_event   (on pcspkr_event%return in pcspkr)

        You can now use it in all perf tools, such as:

                perf record -e probe:pcspkr_event -aR sleep 1

      irqchip/gic-v3-its: Count additional LPIs for the aliased devices

      When configuring the interrupt mapping for a new device, we
      iterate over all the possible aliases to account for their
      maximum MSI allocation. This was introduced by e8137f4f5088
      ("irqchip: gicv3-its: Iterate over PCI aliases to generate ITS 
configuration").

      Turns out that the code doing that is a bit braindead, and repeatedly
      accounts for the same device over and over.

      Fix this by counting the actual alias that is passed to us by the
      core code.

      The warning is fairly benign (there is no code path that could
      actually use uninitialized variables), but let's silence it anyway
      by zeroing the variables on the error path.

      MIPS: Octeon: Fix kernel panic on startup from memory corruption

      During development it was found that a number of builds would panic
      during the kernel init process, more specifically in 'delayed_fput()'.
      The panic showed the kernel trying to access a memory address of
      '0xb7fdc00' while traversing the 'delayed_fput_list' structure.
      Comparing this memory address to the value of the pointer used on
      builds that did not panic confirmed that the pointer on crashing
      builds must have been corrupted at some stage earlier in the init
      process.

      By traversing the list earlier and earlier in the code it was found
      that 'plat_mem_setup()' was responsible for corrupting the list.
      Specifically the line:

          memory = cvmx_bootmem_phy_alloc(mem_alloc_size,
                        __pa_symbol(&__init_end), -1,
                        0x100000,
                        CVMX_BOOTMEM_FLAG_NO_LOCKING);

      Which would eventually call:

          cvmx_bootmem_phy_set_size(new_ent_addr,
                cvmx_bootmem_phy_get_size
                (ent_addr) -
                (desired_min_addr -
                        ent_addr));

      Where 'new_ent_addr'=0x4800000 (the address of 'delayed_fput_list')
      and the second argument (size)=0xb7fdc00 (the address causing the
      kernel panic). The job of this part of 'plat_mem_setup()' is to
      allocate chunks of memory for the kernel to use. At the start of
      each chunk of memory the size of the chunk is written, hence the
      value 0xb7fdc00 is written onto memory at 0x4800000, therefore the
      kernel panics when it goes back to access 'delayed_fput_list' later
      on in the initialisation process.

      On builds that were not crashing it was found that the compiler had
      placed 'delayed_fput_list' at 0x4800008, meaning it wasn't corrupted
      (but something else in memory was overwritten).

      As can be seen in the first function call above the code begins to
      allocate chunks of memory beginning from the symbol '__init_end'.
      The MIPS linker script (vmlinux.lds.S) however defines the .bss
      section to begin after '__init_end'. Therefore memory within the
      .bss section is allocated to the kernel to use (System.map shows
      'delayed_fput_list' and other kernel structures to be in .bss).

      To stop the kernel panic (and the .bss section being corrupted)
      memory should begin being allocated from the symbol '_end'.

      MIPS: Fix R2300 FP context switch handling

      Commit 1a3d59579b9f ("MIPS: Tidy up FPU context switching") removed FP
      context saving from the asm-written resume function in favour of reusing
      existing code to perform the same task. However it only removed the FP
      context saving code from the r4k_switch.S implementation of resume.
      Remove it from the r2300_switch.S implementation too in order to prevent
      attempting to save the FP context twice, which would likely lead to an
      exception from the second save because the FPU had already been disabled
      by the first save.

      This patch has only been build tested, using rbtx49xx_defconfig.

      MIPS: Fix octeon FP context switch handling

      Commit 1a3d59579b9f ("MIPS: Tidy up FPU context switching") removed FP
      context saving from the asm-written resume function in favour of reusing
      existing code to perform the same task. However it only removed the FP
      context saving code from the r4k_switch.S implementation of resume.
      Octeon uses its own implementation in octeon_switch.S, so remove FP
      context saving there too in order to prevent attempting to save context
      twice. That formerly led to an exception from the second save as follows
      because the FPU had already been disabled by the first save:

      ASoC: dwc: fix dma stop transferring issue

      Designware I2S uses tx empty and rx available signals as the DMA
      handshaking signals. during music playing, if XRUN occurs,
      i2s_stop() function will be executed and both tx and rx irq are
      masked, when music continues to be played, i2s_start() is executed
      but both tx and rx irq are not unmasked which cause I2S stop
      sending DMA handshaking signal to DMA controller, and it finally
      causes music playing will be stopped once XRUN occurs for the first
      time.

      systems -- broonie]

      dm raid: fix round up of default region size

      Commit 3a0f9aaee028 ("dm raid: round region_size to power of two")
      intended to make sure that the default region size is a power of two.
      However, the logic in that commit is incorrect and sets the variable
      region_size to 0 or 1, depending on whether min_region_size is a power
      of two.

      Fix this logic, using roundup_pow_of_two(), so that region_size is
      properly rounded up to the next power of two.

      gpio: omap: move pm runtime in irq_chip.irq_bus_lock/sync_unlock

      The PM runtime API can't be used in atomic contex on -RT even if
      it's configured as irqsafe. As result, below error report can
      be seen when PM runtime API called from IRQ chip's callbacks
      irq_startup/irq_shutdown/irq_set_type, because they are
      protected by RAW spinlock:

      The IRQ chip interface defines only two callbacks which are executed in

      PM runtime calls there.

      of groups of the last pinctl instance which is not initialized.

      iMX7D supports two iomux controllers (iomuxc-lpsr and iomuxc) on probing

        I concede the latter really *should* have been submitted during the

      gpio: add DT bindings for existing consumer flags

      It is customary for GPIO controllers to support open drain/collector
      and open source/emitter configurations. Add standard GPIO line flags
      to account for this and augment the documentation to say that these
      are the most generic bindings.

      Several people approached me to add new flags to the lines, and this
      makes sense, but let's first bind up the most common cases before we
      start to add exotic stuff.

      Thanks to H. Nikolaus Schaller for ideas on how to encode single-ended
      wiring such as open drain/source and open collector/emitter.

      The parameter offset is an unsigned, so it makes no sense to compare
      it for >= 0. Fix the compiler warning regarding this by removing this
      comparison.

      As the macro GPIO_OFFSET_VALID is only used at this single place, simplify
      the code by dropping the macro completely and dropping the invert, too.

      pinctrl: imx25: ensure that a pin with id i is at position i in the info

      The code in pinctrl-imx.c only works correctly if in the
      imx_pinctrl_soc_info passed to imx_pinctrl_probe we have:

        info->pins[i].number = i
        conf_reg(info->pins[i]) = 4 * i

      (which conf_reg(pin) being the offset of the pin's configuration
      register).

      When the imx25 specific part was introduced in b4a87c9b966f ("pinctrl:
      pinctrl-imx: add imx25 pinctrl driver") we had:

        info->pins[i].number = i + 1
        conf_reg(info->pins[i]) = 4 * i

      . Commit 34027ca2bbc6 ("pinctrl: imx25: fix numbering for pins") tried
      to fix that but made the situation:

        info->pins[i-1].number = i
        conf_reg(info->pins[i-1]) = 4 * i

      which is hardly better but fixed the error seen back then.

      So insert another reserved entry in the array to finally yield:

        info->pins[i].number = i
        conf_reg(info->pins[i]) = 4 * i

      This is because when using function graph tracer, if the traced
      function return value is in multi regs ([x0-x7]), return_to_handler
      may corrupt them. So in return_to_handler, the parameter regs should
      be protected properly.

      pinctrl: sh-pfc: modify PINMUX_IPSR_MSEL() macro order

      The difference between PINMUX_IPSR_MSEL() and PINMUX_IPSR_MODSEL_DATA()
      are FN_xxx order, and PINMUX_IPSR_MSEL() is used only from r8a7778.
      Now it r8a7778 works correctly with PINMUX_IPSR_MODSEL_DATA() order.
      This means we can merge PINMUX_IPSR_MSEL() and PINMUX_IPSR_MODSEL_DATA().

      Current PFC driver is very difficult to read, because macro names are
      using different length. Especially PINMUX_IPSR_MODSEL_DATA() is well

      pinctrl: sh-pfc: r8a7791/r8a7793: Correct SCIFB1_B SCK MOD_SEL value

      When using serial port SCIFB1_B, transmit works, but nothing is
      received.

      Receive fails because the SCIFB1_SCK_B settings configure the wrong
      value for the sel_scifb1 field in the Module Select Register (MOD_SEL),
      due to an ambiguity in the R-Car M2-W and M2-N datasheets.

      Tested on r8a7791/koelsch using pins 53 (TXD) and 72 (RXD) on EXIO

      MIPS: BPF: Fix load delay slots.

      The entire bpf_jit_asm.S is written in noreorder mode because "we know
      better" according to a comment.  This also prevented the assembler from
      throwing in the required NOPs for MIPS I processors which have no
      load-use interlock, thus the load's consumer might end up using the
      old value of the register from prior to the load.

      Fixed by putting the assembler in reorder mode for just the affected
      load instructions.  This is not enough for gas to actually try to be
      clever by looking at the next instruction and inserting a nop only
      when needed but as the comment said "we know better", so getting gas
      to unconditionally emit a NOP is just right in this case and prevents
      adding further ifdefery.

      x86/kexec: Fix kexec crash in syscall kexec_file_load()

      The original bug is a page fault crash that sometimes happens
      on big machines when preparing ELF headers:

          BUG: unable to handle kernel paging request at ffffc90613fc9000
          IP: [<ffffffff8103d645>] 
prepare_elf64_ram_headers_callback+0x165/0x260

      The bug is caused by us under-counting the number of memory ranges
      and subsequently not allocating enough ELF header space for them.
      The bug is typically masked on smaller systems, because the ELF header
      allocation is rounded up to the next page.

      This patch modifies the code in fill_up_crash_elf_data() by using
      walk_system_ram_res() instead of walk_system_ram_range() to correctly
      count the max number of crash memory ranges. That's because the
      walk_system_ram_range() filters out small memory regions that
      reside in the same page, but walk_system_ram_res() does not.

      Here's how I found the bug:

      After tracing prepare_elf64_headers() and 
prepare_elf64_ram_headers_callback(),
      the code uses walk_system_ram_res() to fill-in crash memory regions 
information
      to the program header, so it counts those small memory regions that
      reside in a page area.

      But, when the kernel was using walk_system_ram_range() in
      fill_up_crash_elf_data() to count the number of crash memory regions,
      it filters out small regions.

      I printed those small memory regions, for example:

        kexec: Get nr_ram ranges. vaddr=0xffff880077592258 paddr=0x77592258, 
sz=0xdc0

      Based on the code in walk_system_ram_range(), this memory region
      will be filtered out:

        pfn = (0x77592258 + 0x1000 - 1) >> 12 = 0x77593
        end_pfn = (0x77592258 + 0xfc0 -1 + 1) >> 12 = 0x77593
        end_pfn - pfn = 0x77593 - 0x77593 = 0  <=== if (end_pfn > pfn) is FALSE

      So, the max_nr_ranges that's counted by the kernel doesn't include
      small memory regions - causing us to under-allocate the required space.
      That causes the page fault crash that happens in a later code path
      when preparing ELF headers.

      This bug is not easy to reproduce on small machines that have few
      CPUs, because the allocated page aligned ELF buffer has more free
      space to cover those small memory regions' PT_LOAD headers.

      clk: ti: dflt: fix enable_reg validity check

      The default clock enabling functions for TI clocks -
      omap2_dflt_clk_enable() and omap2_dflt_clk_disable() perform a
      NULL check for the enable_reg field of the clk_hw_omap structure.
      This enable_reg field however is merely a combination of the index
      of the master IP module, and the offset from the master IP module's
      base address. A value of 0 is perfectly valid, and the current error
      checking will fail in these cases. The issue was found when trying
      to enable the iva2_ck clock on OMAP3 platforms.

      So, switch the check to use IS_ERR. This correction is similar to the
      logic used in commit c807dbedb5e5 ("clk: ti: fix ti_clk_get_reg_addr
      error handling").

      clk: ti: fix dual-registration of uart4_ick

      On the OMAP AM3517 platform the uart4_ick gets registered
      twice, causing any power management to /dev/ttyO3 to fail
      when trying to wake the device up.

      This solves the following oops:

      [] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa09e008

      drm/dp/mst: drop cancel work sync in the mstb destroy path (v2)

      drm/dp/mst: make sure mst_primary mstb is valid in work function

      we validate the mstb structs in the work function, and doing
      that takes a reference. So we should never get here with the
      work function running using the mstb device, only if the work
      function hasn't run yet or is running for another mstb.

      So we don't need to sync the work here, this was causing
      lockdep spew as below.

      drm/dp/mst: split connector registration into two parts (v2)

      In order to cache the EDID properly for tiled displays, we
      need to retrieve it before we register the connector with
      userspace, otherwise userspace can call get resources
      and try and get the edid before we've even cached it.

      This fixes some problems when hotplugging mst monitors,
      with X/mutter running. As mutter seems to get 0 modes
      for one of the monitors in the tile.

      v2: fix warning in radeon
      handle tile setting in cached path rather than
      get edid path.

      drm/dp/mst: fixup handling hotplug on port removal.

      output ports should always have a connector, unless
      in the rare case connector allocation fails in the
      driver.

      In this case we only need to teardown the pdt,
      and free the struct, and there is no need to
      send a hotplug msg.

      In the case were we add the port to the destroy
      list we need to send a hotplug if we destroy
      any connectors, so userspace knows to reprobe
      stuff.

      this patch also handles port->connector allocation
      failing which should be a rare event, but makes
      the code consistent.

      [SMB3] Do not fall back to SMBWriteX in set_file_size error cases

      The error paths in set_file_size for cifs and smb3 are incorrect.

      In the unlikely event that a server did not support set file info
      of the file size, the code incorrectly falls back to trying SMBWriteX
      (note that only the original core SMB Write, used for example by DOS,
      can set the file size this way - this actually  does not work for the more
      recent SMBWriteX).  The idea was since the old DOS SMB Write could set
      the file size if you write zero bytes at that offset then use that if
      server rejects the normal set file info call.

      Fortunately the SMBWriteX will never be sent on the wire (except when
      file size is zero) since the length and offset fields were reversed
      in the two places in this function that call SMBWriteX causing
      the fall back path to return an error. It is also important to never call
      an SMB request from an SMB2/sMB3 session (which theoretically would
      be possible, and can cause a brief session drop, although the client
      recovers) so this should be fixed.  In practice this path does not happen
      with modern servers but the error fall back to SMBWriteX is clearly wrong.

      Removing the calls to SMBWriteX in the error paths in cifs_set_file_size

       "These are fixes mostly, for a few changes made in this cycle (the
        intel_idle driver, the OPP library, the ACPI EC driver, turbostat) and
        for some issues that have just been discovered (ACPI PCI IRQ
        management, PCI power management documentation, turbostat), with a
        couple of cleanups on top of them.

        Specifics:

         - intel_idle driver fixup for the recently added Skylake chips
           support (Len Brown).

         - Operating Performance Points (OPP) library fix related to the
           recently added support for new DT bindings and a fix for a typo in
           a comment (Viresh Kumar, Stephen Boyd).

         - ACPI EC driver fix for a recently introduced memory leak in an
           error code path (Lv Zheng).

         - ACPI PCI IRQ management fix for the issue where an ISA IRQ is
           shared with a PCI device which requires it to be configured in a
           different way and may cause an interrupt storm to happen as a
           result with an extra ACPI SCI IRQ handling simplification on top of
           it (Jiang Liu).

         - Update of the PCI power management documentation that became
           outdated and started to actively confuse the readers to make it
           actually reflect the code (Rafael J Wysocki).

         - turbostat fixes including an IVB Xeon regression fix (related to
           the --debug command line option), Skylake adjustment for the TSC
           running at a frequency that doesn't match the base one exactly, and
           a Knights Landing quirk to account for the fact that it only
           updates APERF and MPERF every 1024 clock cycles plus bumping up the

      dmapool: fix overflow condition in pool_find_page()

      If a DMA pool lies at the very top of the dma_addr_t range (as may
      happen with an IOMMU involved), the calculated end address of the pool
      wraps around to zero, and page lookup always fails.

      Tweak the relevant calculation to be overflow-proof.

      Commit 3033f14ab78c ("clone: support passing tls argument via C rather
      than pt_regs magic") introduced _do_fork() that allowed to pass @tls
      parameter.

      The old do_fork() is defined only for architectures that are not ready
      to use this way and do not define HAVE_COPY_THREAD_TLS.

      Let's use _do_fork() in the kprobe examples to make them work again on
      all architectures.

      memcg: make mem_cgroup_read_stat() unsigned

      mem_cgroup_read_stat() returns a page count by summing per cpu page
      counters.  The summing is racy wrt.  updates, so a transient negative
      sum is possible.  Callers don't want negative values:

       - mem_cgroup_wb_stats() doesn't want negative nr_dirty or nr_writeback.
         This could confuse dirty throttling.

       - oom reports and memory.stat shouldn't show confusing negative usage.

       - tree_usage() already avoids negatives.

      Avoid returning negative page counts from mem_cgroup_read_stat() and
      convert it to unsigned.

      memcg: fix dirty page migration

      The problem starts with a file backed dirty page which is charged to a
      memcg.  Then page migration is used to move oldpage to newpage.

      Migration:
       - copies the oldpage's data to newpage
       - clears oldpage.PG_dirty
       - sets newpage.PG_dirty
       - uncharges oldpage from memcg
       - charges newpage to memcg

      Clearing oldpage.PG_dirty decrements the charged memcg's dirty page
      count.

      However, because newpage is not yet charged, setting newpage.PG_dirty
      does not increment the memcg's dirty page count.  After migration
      completes newpage.PG_dirty is eventually cleared, often in
      account_page_cleaned().  At this time newpage is charged to a memcg so
      the memcg's dirty page count is decremented which causes underflow
      because the count was not previously incremented by migration.  This
      underflow causes balance_dirty_pages() to see a very large unsigned
      number of dirty memcg pages which leads to aggressive throttling of
      buffered writes by processes in non root memcg.

      This issue:
       - can harm performance of non root memcg buffered writes.
       - can report too small (even negative) values in
         memory.stat[(total_)dirty] counters of all memcg, including the root.

      To avoid polluting migrate.c with #ifdef CONFIG_MEMCG checks, introduce
      page_memcg() and set_page_memcg() helpers.

      Test:
          0) setup and enter limited memcg
          mkdir /sys/fs/cgroup/test
          echo 1G > /sys/fs/cgroup/test/memory.limit_in_bytes
          echo $$ > /sys/fs/cgroup/test/cgroup.procs

          1) buffered writes baseline
          dd if=/dev/zero of=/data/tmp/foo bs=1M count=1k
          sync
          grep ^dirty /sys/fs/cgroup/test/memory.stat

          2) buffered writes with compaction antagonist to induce migration
          yes 1 > /proc/sys/vm/compact_memory &
          rm -rf /data/tmp/foo
          dd if=/dev/zero of=/data/tmp/foo bs=1M count=1k
          kill %
          sync
          grep ^dirty /sys/fs/cgroup/test/memory.stat

          3) buffered writes without antagonist, should match baseline
          rm -rf /data/tmp/foo
          dd if=/dev/zero of=/data/tmp/foo bs=1M count=1k
          sync
          grep ^dirty /sys/fs/cgroup/test/memory.stat

                             (speed, dirty residue)
                   unpatched                       patched
          1) 841 MB/s 0 dirty pages          886 MB/s 0 dirty pages

          3) 114 MB/s -33427456 dirty pages  891 MB/s 0 dirty pages

          Notice that unpatched baseline performance (1) fell after
          migration (3): 841 -> 114 MB/s.  In the patched kernel, post
          migration performance matches baseline.

      mm: hugetlbfs: skip shared VMAs when unmapping private pages to satisfy a 
fault

      SunDong reported the following on

        https://bugzilla.kernel.org/show_bug.cgi?id=103841

        I think I find a linux bug, I have the test cases is constructed. I
        can stable recurring problems in fedora22(4.0.4) kernel version,
        arch for x86_64.  I construct transparent huge page, when the parent
        and child process with MAP_SHARE, MAP_PRIVATE way to access the same
        huge page area, it has the opportunity to lead to huge page copy on
        write failure, and then it will munmap the child corresponding mmap
        area, but then the child mmap area with VM_MAYSHARE attributes, child
        process munmap this area can trigger VM_BUG_ON in set_vma_resv_flags
        functions (vma - > vm_flags & VM_MAYSHARE).

      There were a number of problems with the report (e.g.  it's hugetlbfs that
      triggers this, not transparent huge pages) but it was fundamentally
      correct in that a VM_BUG_ON in set_vma_resv_flags() can be triggered that
      looks like this

         vma ffff8804651fd0d0 start 00007fc474e00000 end 00007fc475e00000
         next ffff8804651fd018 prev ffff8804651fd188 mm ffff88046b1b1800
         prot 8000000000000027 anon_vma           (null) vm_ops ffffffff8182a7a0
         pgoff 0 file ffff88106bdb9800 private_data           (null)
         flags: 
0x84400fb(read|write|shared|mayread|maywrite|mayexec|mayshare|dontexpand|hugetlb)
         ------------
         kernel BUG at mm/hugetlb.c:462!
         SMP
         Modules linked in: xt_pkttype xt_LOG xt_limit [..]
         CPU: 38 PID: 26839 Comm: map Not tainted 4.0.4-default #1
         Hardware name: Dell Inc. PowerEdge R810/0TT6JF, BIOS 2.7.4 04/26/2012
         set_vma_resv_flags+0x2d/0x30

      The VM_BUG_ON is correct because private and shared mappings have
      different reservation accounting but the warning clearly shows that the
      VMA is shared.

      When a private COW fails to allocate a new page then only the process
      that created the VMA gets the page -- all the children unmap the page.
      If the children access that data in the future then they get killed.

      The problem is that the same file is mapped shared and private.  During
      the COW, the allocation fails, the VMAs are traversed to unmap the other
      private pages but a shared VMA is found and the bug is triggered.  This
      patch identifies such VMAs and skips them.

      mm/slab: fix unexpected index mapping result of kmalloc_size(INDEX_NODE+1)

      Commit description is copied from the original post of this bug:

        http://comments.gmane.org/gmane.linux.kernel.mm/135349

      Kernels after v3.9 use kmalloc_size(INDEX_NODE + 1) to get the next
      larger cache size than the size index INDEX_NODE mapping.  In kernels
      3.9 and earlier we used malloc_sizes[INDEX_L3 + 1].cs_size.

      However, sometimes we can't get the right output we expected via
      kmalloc_size(INDEX_NODE + 1), causing a BUG().

      The mapping table in the latest kernel is like:
          index = {0,   1,  2 ,  3,  4,   5,   6,   n}
           size = {0,   96, 192, 8, 16,  32,  64,   2^n}
      The mapping table before 3.10 is like this:
          index = {0 , 1 , 2,   3,  4 ,  5 ,  6,   n}
          size  = {32, 64, 96, 128, 192, 256, 512, 2^(n+3)}

      The problem on my mips64 machine is as follows:

      (1) When configured DEBUG_SLAB && DEBUG_PAGEALLOC && DEBUG_LOCK_ALLOC
          && DEBUG_SPINLOCK, the sizeof(struct kmem_cache_node) will be "150",
          and the macro INDEX_NODE turns out to be "2": #define INDEX_NODE
          kmalloc_index(sizeof(struct kmem_cache_node))

      (2) Then the result of kmalloc_size(INDEX_NODE + 1) is 8.

      (3) Then "if(size >= kmalloc_size(INDEX_NODE + 1)" will lead to "size
          = PAGE_SIZE".

      (4) Then "if ((size >= (PAGE_SIZE >> 3))" test will be satisfied and
          "flags |= CFLGS_OFF_SLAB" will be covered.

      (5) if (flags & CFLGS_OFF_SLAB)" test will be satisfied and will go to
          "cachep->slabp_cache = kmalloc_slab(slab_size, 0u)", and the result
          here may be NULL while kernel bootup.

      (6) Finally,"BUG_ON(ZERO_OR_NULL_PTR(cachep->slabp_cache));" causes the
          BUG info as the following shows (may be only mips64 has this problem):

      This patch fixes the problem of kmalloc_size(INDEX_NODE + 1) and removes
      the BUG by adding 'size >= 256' check to guarantee that all necessary
      small sized slabs are initialized regardless sequence of slab size in
      mapping table.

      userfaultfd: remove kernel header include from uapi header

      As include/uapi/linux/userfaultfd.h is a user visible header file, it
      should not include kernel-exclusive header files.

      So trying to build the userfaultfd test program from the selftests
      directory fails, since it contains a reference to linux/compiler.h.  As
      it turns out, that header is not really needed there, so we can simply
      remove it to fix that issue.

      possible null pointer dereferences due to the new ordering and
      initialization on port add/del, and patch 03 moves the "pvid" member in
      the net_bridge_vlan_group struct in order to simplify code (similar to how
      it was with the older struct). Patch 05 fixes adding a vlan on a port 
which
      is pvid and doesn't have a global context yet.
      Please review carefully, I think this is the first use of rhashtable's
      "locks_mul" member in the tree and I'd like to make sure it's correct.
      Another thing that needs special attention is the nbp_vlan_flush() move
      after the rx_handler unregister.

      bridge: vlan: don't pass flags when creating context only

      We should not pass the original flags when creating a context vlan only
      because they may contain some flags that change behaviour in the bridge.
      The new global context should be with minimal set of flags, so pass 0
      and let br_vlan_add() set the master flag only.

      bridge: vlan: fix possible null ptr derefs on port init and deinit

      When a new port is being added we need to make vlgrp available after
      rhashtable has been initialized and when removing a port we need to
      flush the vlans and free the resources after we're sure noone can use
      the port, i.e. after it's removed from the port list and synchronize_rcu
      is executed.

      bridge: vlan: move pvid inside net_bridge_vlan_group

      One obvious way to converge more code (which was also used by the
      previous vlan code) is to move pvid inside net_bridge_vlan_group. This
      allows us to simplify some and remove other port-specific functions.
      Also gives us the ability to simply pass the vlan group and use all of the
      contained information.

      bridge: vlan: fix possible null vlgrp deref while registering new port

      While a new port is being initialized the rx_handler gets set, but the
      vlans get initialized later in br_add_if() and in that window if we
      receive a frame with a link-local address we can try to dereference
      p->vlgrp in:
      br_handle_frame() -> br_handle_local_finish() -> br_should_learn()

      bridge: vlan: adjust rhashtable initial size and hash locks size

      As Stephen pointed out the default initial size is more than we need, so
      let's start small (4 elements, thus nelem_hint = 3). Also limit the hash
      locks to the number of CPUs as we don't need any write-side scaling and
      this looks like the minimum.

      scsi_dh: Use the correct module name when loading device handler

      This fixes a bug in recent kernels which results in failure to boot
      on systems that have multipath SCSI disks.  I observed this failure
      on a POWER8 server where all the disks are multipath SCSI disks.
      The symptoms are several messages like this on the console:

      [    3.018700] device-mapper: table: 253:0: multipath: error attaching 
hardware handler
      [    3.018828] device-mapper: ioctl: error adding target to table

      and the system does not find its disks, and therefore fails to boot.

      Bisection revealed that the bug was introduced in commit 566079c849cf,
      "dm-mpath, scsi_dh: request scsi_dh modules in scsi_dh, not dm-mpath".
      The specific reason for the failure is that where we previously loaded
      the "scsi_dh_alua" module, we are now trying to load the "alua" module,
      which doesn't exist.

      To fix this, we change the request_module call in scsi_dh_lookup()
      to prepend "scsi_dh_" to the name, just like the old code in
      drivers/md/dm-mpath.c:parse_hw_handler() used to do.

      arm64: Fix THP protection change logic

      6910fa1 ("arm64: enable PTE type bit in the mask for pte_modify") fixes
      a problem whereby a large block of PROT_NONE mapped memory is
      incorrectly mapped as block descriptors when mprotect is called.

      Unfortunately, a subtle bug was introduced by this fix to the THP logic.

      If one mmaps a large block of memory, then faults it such that it is
      collapsed into THPs; resulting calls to mprotect on this area of memory
      will lead to incorrect table descriptors being written instead of block
      descriptors. This is because pmd_modify calls pte_modify which is now
      allowed to modify the type of the page table entry.

      This patch reverts commit 6910fa16dbe142f6a0fd0fd7c249f9883ff7fc8a, and
      fixes the problem it was trying to address by adjusting PAGE_NONE to
      represent a table entry. Thus no change in pte type is required when
      moving from PROT_NONE to a different protection.

      net: sfc: avoid using timespec

      The sfc driver internally uses a time format based on 32-bit (unsigned)
      seconds and 32-bit nanoseconds. This means it will overflow in 2106,
      but the value we pass into it is a signed 32-bit tv_sec that already
      overflows in 2038 to a negative value.

      This patch changes the logic to use the lower 32 bits of the timespec64
      tv_sec in efx_ptp_ns_to_s_ns, which will have the correct value beyond 
the overflow.
      While this does not change any of the register values, it lets us
      keep using the driver after we deprecate the use of the timespec type
      in the kernel.

      In the efx_ptp_process_times function, the change to use timespec64
      is similar, in that the tv_sec portion is ignored anyway and we only
      care about the nanosecond portion that remains unchanged.

      ntp/pps: use y2038 safe types in pps_event_time

      The pps_event_time uses two 'timespec' structures internally, which
      suffer from the y2038 problem. The uses of this structure are
      fairly self-contained in the pps code, so this replaces them all at
      once.

      Unfortunately, this includes the sfc ethernet driver aside from the
      pps subsystem, so we change that one as well. Both touch the
      same data structure, and there probably is no good way to split
      the patch into smaller units.

      The sync_cmos_clock has one use of struct timespec, which we want to
      eventually replace with timespec64 or similar in the kernel. There
      is no way this one can overflow, but the conversion to timespec64
      is trivial and has no other dependencies.

      ntp/pps: replace getnstime_raw_and_real with 64-bit version

      There is exactly one caller of getnstime_raw_and_real in the kernel,
      which is the pps_get_ts function. This changes the caller and
      the implementation to work on timespec64 types rather than timespec,
      to avoid the time_t overflow on 32-bit architectures.

      For consistency with the other new functions (ktime_get_seconds,
      ktime_get_real_*, ...), I'm renaming the function to
      ktime_get_raw_and_real_ts64.

      We still need to convert from the internal 64-bit type to 32 bit
      types in the caller, but this conversion is now pushed out from
      getnstime_raw_and_real to pps_get_ts. A follow-up patch changes
      the remaining pps code to completely avoid the conversion.

      ntp/pps: use timespec64 for hardpps()

      There is only one user of the hardpps function in the kernel, so
      it makes sense to atomically change it over to using 64-bit
      timestamps for y2038 safety. In the hardpps implementation,
      we also need to change the pps_normtime structure, which is
      similar to struct timespec and also requires a 64-bit
      seconds portion.

      This introduces two temporary variables in pps_kc_event() to
      do the conversion, they will be removed again in the next step,
      which seemed preferable to having a larger patch changing it
      all at the same time.

      Use WARN_ON_ONCE for missing X86_FEATURE_NRIPS

      The cpu feature flags are not ever going to change, so warning
      everytime can cause a lot of kernel log spam
      (in our case more than 10GB/hour).

      The warning seems to only occur when nested virtualization is
      enabled, so it's probably triggered by a KVM bug.  This is a
      sensible and safe change anyway, and the KVM bug fix might not
      be suitable for stable releases anyway.

      perf report: Fix a bug on "--call-graph none" option

      The patch f9db0d0f1b2c ("perf callchain: Allow disabling call graphs
      per event") added an ability to enable/disable callchain recording per
      event.  But it had a problem when the enablement setting is changed at
      'perf report' time using -g/--call-graph option.

      For example, the following scenario will get a segfault.

        $ perf record -ag sleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.500 MB perf.data (2555 samples) ]

        $ perf report -g none
        perf: Segmentation fault
        -------- backtrace --------
        perf[0x53a98a]
        /usr/lib/libc.so.6(+0x335af)[0x7f4e91df95af]

      This is because callchain_param.sort() callback was not set but it
      tried to call the function as it had the PERF_SAMPLE_CALLCHAIN bit.

      perf top: Fix unresolved comm when -s comm is used

      The perf top uses 'dso,symbol' sort keys by default so it overlooked a
      problem in task's comm resolving.  When the sort key contains 'comm',
      some task's comm is not shown properly.  This is because the
      perf_top__mmap_read_idx() checks the cpumode value improperly.

      The cpumode value of non-sample events are 0 (PERF_RECORD_MISC_CPUMODE_
      UNKNOWN) so the events will be ignored by the switch statement.  This 
patch

      perf record: Allocate area for sample_id_hdr in a synthesized comm event

      A previous patch added a synthesized comm event for forked child process
      but it missed that the event should contain area for sample_id_hdr at
      the end.  It worked by accident since the perf_event union contains
      bigger event structs like mmap_events.

      This patch fixes it by dynamically allocating event struct including
      those area like in perf_event__synthesize_thread_map().

      genirq: Introduce generic irq migration for cpu hotunplug

      ARM and ARM64 have almost identical code for migrating interrupts on
      cpu hotunplug. Provide a generic version which can be used by both.

      The new code addresses a shortcoming in the ARM[64] variants which
      fails to update the affinity change in some cases. The solution for
      this is to use the core function irq_do_set_affinity() instead of open
      coding it.

      The reason is that I forgot the IPv6 fragmentation here. Our MTU of

      reach a payload above 1280 in IPv6 header then we have a IPv6
      fragmentation above 802.15.4 6LoWPAN fragmentation. The type "u16" was
      fine, instead I added now a WARN_ON_ONCE if skb->len is above MTU which
      should never happen otherwise IPv6 on minimum MTU size is broken.

      fs/proc, core/debug: Don't expose absolute kernel addresses via wchan

      So the /proc/PID/stat 'wchan' field (the 30th field, which contains
      the absolute kernel address of the kernel function a task is blocked in)
      leaks absolute kernel addresses to unprivileged user-space:

              seq_put_decimal_ull(m, ' ', wchan);

      The absolute address might also leak via /proc/PID/wchan as well, if
      KALLSYMS is turned off or if the symbol lookup fails for some reason:

      static int proc_pid_wchan(struct seq_file *m, struct pid_namespace *ns,
                                struct pid *pid, struct task_struct *task)
      {
              unsigned long wchan;
              char symname[KSYM_NAME_LEN];

              wchan = get_wchan(task);

              if (lookup_symbol_name(wchan, symname) < 0) {
                      if (!ptrace_may_access(task, PTRACE_MODE_READ))
                              return 0;
                      seq_printf(m, "%lu", wchan);
              } else {
                      seq_printf(m, "%s", symname);
              }

              return 0;
      }

      This isn't ideal, because for example it trivially leaks the KASLR offset
      to any local attacker:

        fomalhaut:~> printf "%016lx\n" $(cat /proc/$$/stat | cut -d' ' -f35)
        ffffffff8123b380

      Most real-life uses of wchan are symbolic:

        ps -eo pid:10,tid:10,wchan:30,comm

      and procps uses /proc/PID/wchan, not the absolute address in 
/proc/PID/stat:

        triton:~/tip> strace -f ps -eo pid:10,tid:10,wchan:30,comm 2>&1 | grep 
wchan | tail -1
        open("/proc/30833/wchan", O_RDONLY)     = 6

      There's one compatibility quirk here: procps relies on whether the
      absolute value is non-zero - and we can provide that functionality
      by outputing "0" or "1" depending on whether the task is blocked
      (whether there's a wchan address).

      These days there appears to be very little legitimate reason
      user-space would be interested in  the absolute address. The
      absolute address is mostly historic: from the days when we
      didn't have kallsyms and user-space procps had to do the
      decoding itself via the System.map.

      So this patch sets all numeric output to "0" or "1" and keeps only
      symbolic output, in /proc/PID/wchan.

      ( The absolute sleep address can generally still be profiled via
        perf, by tasks with sufficient privileges. )

      arm64/efi: Fix boot crash by not padding between EFI_MEMORY_RUNTIME 
regions

      The new Properties Table feature introduced in UEFIv2.5 may
      split memory regions that cover PE/COFF memory images into
      separate code and data regions. Since these regions only differ
      in the type (runtime code vs runtime data) and the permission
      bits, but not in the memory type attributes (UC/WC/WT/WB), the
      spec does not require them to be aligned to 64 KB.

      Since the relative offset of PE/COFF .text and .data segments
      cannot be changed on the fly, this means that we can no longer
      pad out those regions to be mappable using 64 KB pages.
      Unfortunately, there is no annotation in the UEFI memory map
      that identifies data regions that were split off from a code
      region, so we must apply this logic to all adjacent runtime
      regions whose attributes only differ in the permission bits.

      So instead of rounding each memory region to 64 KB alignment at
      both ends, only round down regions that are not directly
      preceded by another runtime region with the same type
      attributes. Since the UEFI spec does not mandate that the memory
      map be sorted, this means we also need to sort it first.

      Note that this change will result in all EFI_MEMORY_RUNTIME
      regions whose start addresses are not aligned to the OS page
      size to be mapped with executable permissions (i.e., on kernels
      compiled with 64 KB pages). However, since these mappings are
      only active during the time that UEFI Runtime Services are being
      invoked, the window for abuse is rather small.

      x86/efi: Fix boot crash by mapping EFI memmap entries bottom-up at 
runtime, instead of top-down

      Beginning with UEFI v2.5 EFI_PROPERTIES_TABLE was introduced
      that signals that the firmware PE/COFF loader supports splitting
      code and data sections of PE/COFF images into separate EFI
      memory map entries. This allows the kernel to map those regions
      with strict memory protections, e.g. EFI_MEMORY_RO for code,
      EFI_MEMORY_XP for data, etc.

      Unfortunately, an unwritten requirement of this new feature is
      that the regions need to be mapped with the same offsets
      relative to each other as observed in the EFI memory map. If
      this is not done crashes like this may occur,

        BUG: unable to handle kernel paging request at fffffffefe6086dd
        IP: [<fffffffefe6086dd>] 0xfffffffefe6086dd
        Call Trace:
         [<ffffffff8104c90e>] efi_call+0x7e/0x100
         [<ffffffff81602091>] ? virt_efi_set_variable+0x61/0x90
         [<ffffffff8104c583>] efi_delete_dummy_variable+0x63/0x70

         [<ffffffff81f37582>] x86_64_start_kernel+0xeb/0xef

      Here 0xfffffffefe6086dd refers to an address the firmware
      expects to be mapped but which the OS never claimed was mapped.
      The issue is that included in these regions are relative
      addresses to other regions which were emitted by the firmware
      toolchain before the "splitting" of sections occurred at
      runtime.

      Needless to say, we don't satisfy this unwritten requirement on
      x86_64 and instead map the EFI memory map entries in reverse
      order. The above crash is almost certainly triggerable with any
      kernel newer than v3.13 because that's when we rewrote the EFI
      runtime region mapping code, in commit d2f7cbe7b26a ("x86/efi:
      Runtime services virtual mapping"). For kernel versions before
      v3.13 things may work by pure luck depending on the
      fragmentation of the kernel virtual address space at the time we
      map the EFI regions.

      Instead of mapping the EFI memory map entries in reverse order,
      where entry N has a higher virtual address than entry N+1, map
      them in the same order as they appear in the EFI memory map to
      preserve this relative offset between regions.

      This patch has been kept as small as possible with the intention
      that it should be applied aggressively to stable and
      distribution kernels. It is very much a bugfix rather than
      support for a new feature, since when EFI_PROPERTIES_TABLE is
      enabled we must map things as outlined above to even boot - we
      have no way of asking the firmware not to split the code/data
      regions.

      In fact, this patch doesn't even make use of the more strict
      memory protections available in UEFI v2.5. That will come later.

      regulator: core: Handle probe deferral from DT when resolving supplies

      When resolving regulator-regulator supplies we ignore probe deferral
      returns from regulator_dev_lookup() (such as are generated for DT when
      we can see a supply is registered) and just fall back to the dummy
      regulator if there are full constraints (as is the case for DT).  This
      means that probe deferral is broken for DT systems, fix that by paying
      attention to -EPROBE_DEFER return codes like we do -ENODEV.

      A further patch will simplify this further, this is a minimal fix for
      the specific issue.

      ipvs: Don't protect ip_vs_addr_is_unicast with CONFIG_SYSCTL

      I arranged the code so that the compiler can remove the unecessary bits
      in ip_vs_leave when CONFIG_SYSCTL is unset, and removed an explicit
      CONFIG_SYSCTL.

      Unfortunately when rebasing my work on top of that of Alex Gartrell I
      missed the fact that the newly added function ip_vs_addr_is_unicast was
      surrounded by CONFIG_SYSCTL.

      So remove the now unnecessary CONFIG_SYSCTL guards around
      ip_vs_addr_is_unicast.  It is causing build failures today when
      CONFIG_SYSCTL is not selected and any self respecting compiler will
      notice that sysctl_cache_bypass is always false without CONFIG_SYSCTL
      and not include the logic from the function ip_vs_addr_is_unicast in
      the compiled code.

      dmaengine: pxa_dma: fix residue corner case

      A very tiny temporal window exists in the residue calculation where :
       - upon entering residue calculation, the transfer is ongoing
       - when reading the current transfer pointer, it just changed to
         the "finisher/linker" descriptor

      In this case, the residue returned is the whole transfer length instead
      of 0. Fix it.

      This appears almost in one extreme case, where the driver is used
      by older clients which inquire for residue in interrupt context, such
      as the smsc91x ethernet driver, in a tight loop :
        interrupt_handler()
          dmaengine_submit()
          do {

      cxl: fix leak of ctx->mapping when releasing kernel API contexts

      When a context is created via the kernel API, ctx->mapping is allocated
      within the kernel and thus needs to be freed when the context is freed.
      reclaim_ctx() attempts to do this for contexts with the ctx->kernelapi 
flag
      set, but afu_release() (which can be called from the kernel API through
      cxl_fd_release()) sets ctx->mapping to NULL before calling
      cxl_context_free() to free the context.

      Add a check to afu_release() so that the mappings in contexts created via
      the kernel API are left alone so reclaim_ctx() can free them.

      Move the freeing of ctx->irq_bitmap from afu_release_irqs() to
      reclaim_ctx() (called through cxl_context_free()) so it's freed when
      releasing a context via the kernel API (cxl_release_context()) or the
      userspace API (afu_release()).

      cxl: fix leak of IRQ names in cxl_free_afu_irqs()

      cxl_free_afu_irqs() doesn't free IRQ names when it releases an AFU's IRQ
      ranges. The userspace API equivalent in afu_release_irqs() calls
      afu_irq_name_free() to release the IRQ names.

      Call afu_irq_name_free() in cxl_free_afu_irqs() to release the IRQ names.
      Make afu_irq_name_free() non-static to allow this.

      perf tools: By default use the most precise "cycles" hw counter available

      If the user doesn't specify any event, try the most precise "cycles"
      available, i.e. start by "cycles:ppp" and go on removing "p" till it
      works.

      E.g.

        $ perf record usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.017 MB perf.data (11 samples) ]
        $ perf evlist
        cycles:pp
        $ perf evlist -v
        cycles:pp: size: 112, { sample_period, sample_freq }: 4000, sample_type:
        IP|TID|TIME|PERIOD, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1,
        enable_on_exec: 1, task: 1, precise_ip: 2, sample_id_all: 1,
        exclude_guest: 1, mmap2: 1, comm_exec: 1
        $ grep 'model name' /proc/cpuinfo | head -1
        model name      : Intel(R) Core(TM) i7-3667U CPU @ 2.00GHz
        $

      When 'cycles' appears explicitely is specified this will not be tried,
      i.e. the user has full control of the level of precision to be used:

        $ perf record -e cycles usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.016 MB perf.data (9 samples) ]
        $ perf evlist
        cycles
        $ perf evlist -v
        cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type:
        IP|TID|TIME|PERIOD, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1,
        enable_on_exec: 1, task: 1, sample_id_all: 1, exclude_guest: 1, mmap2:
        1, comm_exec: 1

      perf probe: Fix a segfault bug in debuginfo_cache

      perf probe --list will get a segfault if the first kprobe event is on a
      module and the second or latter one is on the kernel.

      e.g.
        ----
        # ./perf probe -q -m pcspkr pcspkr_event
        # ./perf probe -q vfs_read
        # ./perf probe -l
        Segmentation fault (core dumped)
        ----

      This is because the debuginfo_cache fails to handle NULL module name,
      which causes segfault on strcmp. (Note that strcmp("something", NULL)
      always causes segfault)

      To fix this debuginfo_cache__open always translates the NULL module name
      to "kernel" (this is correct, because NULL module name means opening the
      debuginfo for the kernel)

        ----
        # ./perf probe -l
          probe:pcspkr_event   (on pcspkr_event@drivers/input/misc/pcspkr.c

      perf probe: Show correct source lines of probes on kmodules

      Perf probe always failed to find appropriate line numbers because of
      failing to find .text start address offset from debuginfo.

      e.g.
        ----
        # ./perf probe -m pcspkr pcspkr_event:5
        Added new events:
          probe:pcspkr_event   (on pcspkr_event:5 in pcspkr)
          probe:pcspkr_event_1 (on pcspkr_event:5 in pcspkr)

        You can now use it in all perf tools, such as:

                perf record -e probe:pcspkr_event_1 -aR sleep 1

        # ./perf probe -l
        Failed to find debug information for address ffffffffa031f006
        Failed to find debug information for address ffffffffa031f016
          probe:pcspkr_event   (on pcspkr_event+6 in pcspkr)
          probe:pcspkr_event_1 (on pcspkr_event+22 in pcspkr)
        ----

      This fixes the above issue as below.
      1. Get the relative address of the symbol in .text by using
         map->start.
      2. Adjust the address by adding the offset of .text section
         in the kernel module binary.

      With this fix, perf probe -l shows lines correctly.
        ----
        # ./perf probe -l

      perf probe: Fix to remove dot suffix from second or latter events

      Fix to remove dot suffix (e.g. .const, .isra) from the second or latter

      Since the previous commit 35a23ff928b0 ("perf probe: Cut off the gcc
      optimization postfixes from function name") didn't care about the suffix
      numbered events, therefore we'll have an error when we add additional
      events on the same dot suffix functions.

      e.g.
        ----
        # ./perf probe -f -a get_sigframe.isra.2.constprop.3 \
         -a get_sigframe.isra.2.constprop.3

      perf tools: Fix build break on powerpc due to sample_reg_masks

      The perf_regs.c file does not get built on Powerpc as CONFIG_PERF_REGS
      is false.  So the weak definition for 'sample_regs_masks' doesn't get
      picked up.

      Adding perf_regs.o to util/Build unconditionally, exposes a redefinition
      error for 'perf_reg_value()' function (due to the static inline version
      in util/perf_regs.h). So use #ifdef HAVE_PERF_REGS_SUPPORT' around that
      function.

      perf report: Amend documentation about max_stack and synthesized 
callchains

      The --max_stack option was added as an optimization to reduce processing 
time,
      so people specifying --max-stack might get a increased processing time if
      combined with synthesized callchains, but otherwise no real harm.

      A warning about setting both --max_stack and the synthesized callchains

      perf maps: Introduce maps__find_symbol_by_name()

      Out of map_groups__find_symbol_by_name(), so that we can turn this later
      one first into a call to maps__find_symbol_by_name(MAP__FUNCTION) +
      MAP__VARIABLE, and then to just one call, we'll merge MAP__FUNCTION with
      MAP__VARIABLE maps, to simplify the code.

      x86/process: Add proper bound checks in 64bit get_wchan()

      Dmitry Vyukov reported the following using trinity and the memory
      error detector AddressSanitizer
      
(https://code.google.com/p/address-sanitizer/wiki/AddressSanitizerForKernel).

      [ 124.575597] ERROR: AddressSanitizer: heap-buffer-overflow on

      ./arch/x86/kernel/process_64.c:444

      The address checks in the 64bit implementation of get_wchan() are
      wrong in several ways:

       - The lower bound of the stack is not the start of the stack
         page. It's the start of the stack page plus sizeof (struct
         thread_info)

       - The upper bound must be:

             top_of_stack - TOP_OF_KERNEL_STACK_PADDING - 2 * sizeof(unsigned 
long).

         The 2 * sizeof(unsigned long) is required because the stack pointer
         points at the frame pointer. The layout on the stack is: ... IP FP
         ... IP FP. So we need to make sure that both IP and FP are in the
         bounds.

      Fix the bound checks and get rid of the mix of numeric constants, u64
      and unsigned long. Making all unsigned long allows us to use the same
      function for 32bit as well.

      Use READ_ONCE() when accessing the stack. This does not prevent a
      concurrent wakeup of the task and the stack changing, but at least it
      avoids TOCTOU.

      Also check task state at the end of the loop. Again that does not
      prevent concurrent changes, but it avoids walking for nothing.

      Add proper comments while at it.

      Calling strlen() no less than three times on entry is silly. Since
      we're formatting into a buffer with plenty of room, there's no chance
      of truncation, so snprintf() has actually returned the value we want,
      meaning we don't even have to call strlen once.

      x86/x2apic: Make stub functions available even if !CONFIG_X86_LOCAL_APIC

      Some CONFIG_X86_X2APIC functions, especially x2apic_enabled(), are not
      declared if !CONFIG_X86_LOCAL_APIC.  However, the same stubs that work
      for !CONFIG_X86_X2APIC are okay even if there is no local APIC support
      at all.

      Avoid the introduction of #ifdefs by moving the x2apic declarations
      completely outside the CONFIG_X86_LOCAL_APIC block.  (Unfortunately,
      diff generation messes up the actual change that this patch makes).
      There is no semantic change because CONFIG_X86_X2APIC depends on
      CONFIG_X86_LOCAL_APIC.

      workqueue: make sure delayed work run in local cpu

      My system keeps crashing with below message. vmstat_update() schedules a 
delayed
      work in current cpu and expects the work runs in the cpu.
      schedule_delayed_work() is expected to make delayed work run in local 
cpu. The
      problem is timer can be migrated with NO_HZ. __queue_work() queues work in
      timer handler, which could run in a different cpu other than where the 
delayed
      work is scheduled. The end result is the delayed work runs in different 
cpu.
      The patch makes __queue_delayed_work records local cpu earlier. Where the 
timer
      runs doesn't change where the work runs with the change.

      Initialize msg/shm IPC objects before doing ipc_addid()

      As reported by Dmitry Vyukov, we really shouldn't do ipc_addid() before
      having initialized the IPC object state.  Yes, we initialize the IPC
      object in a locked state, but with all the lockless RCU lookup work,
      that IPC object lock no longer means that the state cannot be seen.

      We already did this for the IPC semaphore code (see commit e8577d1f0329:
      "ipc/sem.c: fully initialize sem_array before making it visible") but we
      clearly forgot about msg and shm.

      RDS: Use per-bucket rw lock for bind hash-table

      One global lock protecting hash-tables with 1024 buckets isn't
      efficient and it shows up in a massive systems with truck
      loads of RDS sockets serving multiple databases. The
      perf data clearly highlights the contention on the rw
      lock in these massive workloads.

      When the contention gets worse, the code gets into a state where
      it decides to back off on the lock. So while it has disabled interrupts,
      it sits and backs off on this lock get. This causes the system to
      become sluggish and eventually all sorts of bad things happen.

      The simple fix is to move the lock into the hash bucket and
      use per-bucket lock to improve the scalability.

      RDS: make socket bind/release locking scheme simple and more efficient

      RDS bind and release locking scheme is very inefficient. It
      uses RCU for maintaining the bind hash-table which is great but
      it also needs to hold spinlock for [add/remove]_bound(). So
      overall usecase, the hash-table concurrent speedup doesn't pay off.
      In fact blocking nature of synchronize_rcu() makes the RDS
      socket shutdown too slow which hurts RDS performance since
      connection shutdown and re-connect happens quite often to
      maintain the RC part of the protocol.

      So we make the locking scheme simpler and more efficient by
      replacing spin_locks with reader/writer locks and getting rid
      off rcu for bind hash-table.

      In subsequent patch, we also covert the global lock with per-bucket
      lock to reduce the global lock contention.

      RDS: use kfree_rcu in rds_ib_remove_ipaddr

      synchronize_rcu() slowing down un-necessarily the socket shutdown
      path. It is used just kfree() the ip addresses in rds_ib_remove_ipaddr()
      which is perfect usecase for kfree_rcu();

      So lets use that to gain some speedup.

      MIPS: dma-default: Fix 32-bit fall back to GFP_DMA

      If there is a DMA zone (usually 24bit = 16MB I believe), but no DMA32
      zone, as is the case for some 32-bit kernels, then massage_gfp_flags()
      will cause DMA memory allocated for devices with a 32..63-bit
      coherent_dma_mask to fall back to using __GFP_DMA, even though there may
      only be 32-bits of physical address available anyway.

      Correct that case to compare against a mask the size of phys_addr_t
      instead of always using a 64-bit mask.

      drm/vmwgfx: Fix a command submission hang regression

      When we're out of command buffer space, we turn on the command buffer
      processed irq without re-checking for finished command buffers afterwards.
      This might lead to a missed irq and the command submission process waiting
      forever for space.

      Fix this by rerunning the command buffer submission handler whenever we're
      out of command space. This ensures both that we don't needlessly turn on
      the irq, and that if we decide to turn on the irq, we recheck for finished
      command buffers before going to sleep.

      i40evf: tweak init timing

      This patch tweaks the init timing of the driver just a little bit to
      increase stability on load/unload and SR-IOV enable/disable cycles.

      First, run the init_task loop a little quicker in order to reduce
      overall init time.

      Second, stagger the start of the init task based on the device's
      PCIe function ID. This lessens the impact on the firmware when a
      whole bunch of VFs are initialized simultaneously, e.g. enabling
      SR-IOV without the VF driver blacklisted. For single VFs assigned
      to VMs this will have no effect as the function ID will always be 0.

      i40e: warn on double free

      Down was requesting queue disables, but then exited immediately without
      waiting for the queues to actually disable. This could allow any

      i40evf_up, and causes a memory leak.

      This issue has been fixed in a recent refactor of the reset code, but

      reintroduce this issue or if we missed any cases.

      The struct i40e_aqc_get_cee_dcb_cfg_v1_resp was originally defined with

directly

      Because the struct doesn't actually change in size or layout, this doesn't
      constitute a change in the API.

      ieee802154: change mtu size behaviour

      This patch changes the mtu size of 802.15.4 interfaces. The current
      setting is the meaning of the maximum transport unit with mac header,
      which is 127 bytes according 802.15.4. The linux meaning of the mtu size
      field is the maximum payload of a mac frame. Like in ethernet, which is
      1500 bytes.

      We have dynamic length of mac frames in 802.15.4, this is why we assume
      the minimum header length which is hard_header_len. This contains fc and
      sequence fields. These can evaluated by driver layer without additional
      checks. We currently don't support to set the FCS from userspace, so we
      need to subtract this from mtu size as well.

      A complete other issue is what doing with HardMAC drivers where the
      payload is always plaintext. I think we need a special handling then in
      userspace. We currently doesn't support any HardMAC transceivers, so we

      netlink: add nla_get for le32 and le64

      This patch adds missing inline wrappers for nla_get_le32 and
      nla_get_le64. The 802.15.4 MAC byteorder is little endian and we keep
      the byteorder for fields like address configuration in the same
      byteorder as it comes from the MAC layer.

      To provide these fields for nl802154 userspace applications, we need
      these inline wrappers for netlink.

      dma_release_channel() decrements privatecnt counter and almost all 
dma_get*
      function increments it with the exception of dma_get_slave_channel().
      In most cases this does not cause issue since normally the channel is not
      requested and released, but if a driver requests DMA channel via
      dma_get_slave_channel() and releases the channel the privatecnt will be
      unbalanced and this will prevent for example getting channel for memcpy.

      Netfilter/IPVS updates for net-next

      The following pull request contains Netfilter/IPVS updates for net-next
      containing 90 patches from Eric Biederman.

      The main goal of this batch is to avoid recurrent lookups for the netns
      pointer, that happens over and over again in our Netfilter/IPVS code. The 
idea
      consists of passing netns pointer from the hook state to the relevant 
functions
      and objects where this may be needed.

      You can find more information on the IPVS updates from Simon Horman's 
commit
      merge message:

      c3456026adc0 ("Merge tag 'ipvs2-for-v4.4' of 
https://git.kernel.org/pub/scm/linux/kernel/git/horms/ipvs-next";).

      Exceptionally, this time, I'm not posting the patches again on netdev, 
Eric
      already Cc'ed this mailing list in the original submission. If you need 
me to

      Vivien Didelot says:

      ====================
      net: switchdev: use specific switchdev_obj_*

      This patchset changes switchdev add, del, dump operations from this:

          int     (*switchdev_port_obj_add)(struct net_device *dev,
                                            struct switchdev_obj *obj,
                                            struct switchdev_trans *trans);
          int     (*switchdev_port_obj_del)(struct net_device *dev,
                                            struct switchdev_obj *obj);
          int     (*switchdev_port_obj_dump)(struct net_device *dev,
                                            struct switchdev_obj *obj);

      to something similar to the notifier_call callback of a notifier_block:

          int     (*switchdev_port_obj_add)(struct net_device *dev,
                                            enum switchdev_obj_id id,
                                            const void *obj,
                                            struct switchdev_trans *trans);
          int     (*switchdev_port_obj_del)(struct net_device *dev,
                                            enum switchdev_obj_id id,
                                            const void *obj);
          int     (*switchdev_port_obj_dump)(struct net_device *dev,
                                             enum switchdev_obj_id id, void 
*obj,
                                             int (*cb)(void *obj));

      This allows the caller to pass and expect back a specific switchdev_obj_*
      structure (e.g. switchdev_obj_fdb) instead of the generic switchdev_obj 
one.

      This will simplify pushing the callback function down to the drivers.

      The first 3 patches get rid of the dev parameter of the dump callback, 
since it
      is not always neeeded (e.g. vlan_dump) and some drivers (such as DSA 
drivers)
      may not have easy access to it.

      Patches 4 and 5 implement the change in the switchdev operations and its 
users.

      Patch 6 extracts the inner switchdev_obj_* structures from switchdev_obj 
and
      removes this last one.

      v2: fix error spotted by kbuild (extra ';' inline 
switchdev_port_obj_dump).

      Similar to the notifier_call callback of a notifier_block, change the

      This happens because __s64 is by default defined as "long" on ppc64,
      not as "long long". However, to fix these warnings, it's possible to
      define the __SANE_USERSPACE_TYPES__ so that __s64 gets defined to
      "long long" on ppc64, too.

      net/mlx4: Handle return codes in mlx4_qp_attach_common

      Both new_steering_entry() and existing_steering_entry() return values
      based on their success or failure, but currently they fall through
      silently.  This can make troubleshooting difficult, as we were unable
      to tell which one of these two functions returned errors or
      specifically what code was returned.  This patch remedies that
      situation by passing the return codes to err, which is returned by
      mlx4_qp_attach_common() itself.

      This also addresses a leak in the call to mlx4_bitmap_free() as well.

      Merge branch 'L3_master_device'

      David Ahern says:

      ====================
      net: L3 master device

      The VRF device is essentially a Layer 3 master device used to associate
      netdevices with a specific routing table and to influence FIB lookups
      via 'ip rules' and controlling the oif/iif used for the lookup.

      This series generalizes the VRF into L3 master device, l3mdev. Similar
      to switchdev it has a Kconfig option and separate set of operations
      in net_device allowing it to be completely compiled out if not wanted.
      The l3mdev methods rely on the 'master' aspect and use of
      netdev_master_upper_dev_get_rcu to retrieve the master device from a
      given netdevice if it is enslaved to an L3_MASTER.

      The VRF device is converted to use the l3mdev operations. At the end the
      vrf_ptr is no longer and removed, as are all direct references to VRF.
      The end result is a much simpler implementation for VRF.

      Thanks to Nikolay for suggestions (eg., use of the master linkage which
      is the key to making this work) and to Roopa, Andy and Shrijeet for
      early reviews.

      v3
      - added license header to l3mdev.c

      - export symbols in l3mdev.c for use with GPL modules

      - removed netdevice header from l3mdev.h (not needed) and fixed
        typo in comment

      v2
      - rebased to top of net-next
      - addressed Niks comments (checking master, removing extra lines, and
        flipping the order of patches 1 and 2)

      tcp: prepare fastopen code for upcoming listener changes

      While auditing TCP stack for upcoming 'lockless' listener changes,
      I found I had to change fastopen_init_queue() to properly init the object
      before publishing it.

      Otherwise an other cpu could try to lock the spinlock before it gets
      properly initialized.

      Instead of adding appropriate barriers, just remove dynamic memory
      allocations :
      - Structure is 28 bytes on 64bit arches. Using additional 8 bytes
        for holding a pointer seems overkill.
      - Two listeners can share same cache line and performance would suffer.

      If we really want to save few bytes, we would instead dynamically allocate
      whole struct request_sock_queue in the future.

      Earlier patch 6ae459bda tried to detect void ckecksum partial
      skb by comparing pull length to checksum offset. But it does
      not work for all cases since checksum-offset depends on
      updates to skb->data.

      Following patch fixes it by validating checksum start offset
      after skb-data pointer is updated. Negative value of checksum
      offset start means there is no need to checksum.

      net: Swap ordering of tests in ip_route_input_mc

      This patch just swaps the ordering of one of the conditional tests in
      ip_route_input_mc.  Specifically it swaps the testing for the source
      address to see if it is loopback, and the test to see if we allow a
      loopback source address.

      The reason for swapping these two tests is because it is much faster to
      test if an address is loopback than it is to dereference several pointers
      to get at the net structure to see if the use of loopback is allowed.

      net/ipv4: Pass proto as u8 instead of u16 in ip_check_mc_rcu

      This patch updates ip_check_mc_rcu so that protocol is passed as a u8
      instead of a u16.

      The motivation is just to avoid any unneeded type transitions since some
      systems will require an instruction to zero extend a u8 field to a u16.
      Also it makes it a bit more readable as to the fact that protocol is a u8
      so there are no byte ordering changes needed to pass it.

      Input: psmouse - fix data race in __ps2_command

      The data race happens on ps2dev->cmdcnt and ps2dev->cmdbuf contents.
      __ps2_command reads that data concurrently with the interrupt handler. As
      the result, for example, if a response arrives just after the timeout,
      __ps2_command can copy out garbage from ps2dev->cmdbuf but then see that
      ps2dev->cmdcnt is 0 and return success.

      Stop the interrupt handler with serio_pause_rx() before reading the
      results.

      The data race was found with KernelThreadSanitizer (KTSAN).

      net: ipv6: Add RT6_LOOKUP_F_IFACE flag if oif is set

      Wolfgang reported that IPv6 stack is ignoring oif in output route lookups:

          With ipv6, ip -6 route get always returns the specific route.

      The stack does consider the oif but a mismatch in rt6_device_match is not
      considered fatal because RT6_LOOKUP_F_IFACE is not set in the flags.

      netpoll: Drop budget parameter from NAPI polling call hierarchy

      For some reason we were carrying the budget value around between the
      various calls to napi->poll.  If for example one of the drivers called had
      a bug in which it returned a non-zero value for work this could result in
      the budget value becoming negative.

      Rather than carry around a value of budget that is 0 or less we can 
instead
      just loop through and pass 0 to each napi->poll call.  If any driver
      returns a value for work done that is non-zero then we can report that
      driver and continue rather than allowing a bad actor to make the budget
      value negative and pass that negative value to napi->poll.

      Note, the only actual change here is that instead of letting budget become
      negative we are keeping it at 0 regardless of the value returned for work
      since it should not be possible for the polling routine to do any actual
      work with a budget of 0.  So if the polling routine returns a non-0 value
      we are just reporting it and continuing with a budget of 0 rather than
      letting that work value be subtracted from the budget of 0.

      This patch set implements a bugfix for kernel.org bugzilla #12323, 
allowing
      MSG_PEEK to return all queued data on the unix domain socket, not just the
      data contained in a single SKB.

      This is the v3 version of this patch, which includes a suggested 
modification
      by Eric Dumazet to convert the unix_sk() conversion macro to a static 
inline
      function. These patches are independent and can be applied separately.

      This set was tested over a 24-hour period, utilizing a loop continually
      executing the bugzilla issue attached python code. It was instrumented 
with
      a pr_err_once() ([   13.798683] unix: went there at least one time).

      v2->v3:
       - Added Eric Dumazet's suggestion for #define to static inline
       - Fixed an issue calling unix_state_lock() with an invalid argument

      v3->v4:

      af_unix: return data from multiple SKBs on recv() with MSG_PEEK flag

      AF_UNIX sockets now return multiple skbs from recv() when MSG_PEEK flag
      is set.

      This is referenced in kernel bugzilla #12323 @
      https://bugzilla.kernel.org/show_bug.cgi?id=12323

      As described both in the BZ and lkml thread @
      http://lkml.org/lkml/2008/1/8/444 calling recv() with MSG_PEEK on an
      AF_UNIX socket only reads a single skb, where the desired effect is
      to return as much skb data has been queued, until hitting the recv
      buffer size (whichever comes first).

      The modified MSG_PEEK path will now move to the next skb in the tree
      and jump to the again: label, rather than following the natural loop
      structure. This requires duplicating some of the loop head actions.

      This was tested using the python socketpair python code attached to
      the bugzilla issue.

      bridge: vlan: add per-vlan struct and move to rhashtables

      This patch changes the bridge vlan implementation to use rhashtables
      instead of bitmaps. The main motivation behind this change is that we
      need extensible per-vlan structures (both per-port and global) so more
      advanced features can be introduced and the vlan support can be
      extended. I've tried to break this up but the moment net_port_vlans is
      changed and the whole API goes away, thus this is a larger patch.
      A few short goals of this patch are:
      - Extensible per-vlan structs stored in rhashtables and a sorted list
      - Keep user-visible behaviour (compressed vlans etc)
      - Keep fastpath ingress/egress logic the same (optimizations to come
        later)

      Here's a brief list of some of the new features we'd like to introduce:
      - per-vlan counters
      - vlan ingress/egress mapping
      - per-vlan igmp configuration
      - vlan priorities
      - avoid fdb entries replication (e.g. local fdb scaling issues)

      The structure is kept single for both global and per-port entries so to
      avoid code duplication where possible and also because we'll soon 
introduce
      "port0 / aka bridge as port" which should simplify things further
      (thanks to Vlad for the suggestion!).

      Now we have per-vlan global rhashtable (bridge-wide) and per-vlan port
      rhashtable, if an entry is added to a port it'll get a pointer to its
      global context so it can be quickly accessed later. There's also a
      sorted vlan list which is used for stable walks and some user-visible
      behaviour such as the vlan ranges, also for error paths.
      VLANs are stored in a "vlan group" which currently contains the
      rhashtable, sorted vlan list and the number of "real" vlan entries.
      A good side-effect of this change is that it resembles how hw keeps
      per-vlan data.
      One important note after this change is that if a VLAN is being looked up
      in the bridge's rhashtable for filtering purposes (or to check if it's an
      existing usable entry, not just a global context) then the new helper
      br_vlan_should_use() needs to be used if the vlan is found. In case the
      lookup is done only with a port's vlan group, then this check can be
      skipped.

      Things tested so far:
      - basic vlan ingress/egress
      - pvids
      - untagged vlans
      - undef CONFIG_BRIDGE_VLAN_FILTERING
      - adding/deleting vlans in different scenarios (with/without global ctx,
        while transmitting traffic, in ranges etc)
      - loading/removing the module while having/adding/deleting vlans
      - extracting bridge vlan information (user ABI), compressed requests
      - adding/deleting fdbs on vlans
      - bridge mac change, promisc mode
      - default pvid change
      - kmemleak ON during the whole time

      ====================
      net: mvneta: Switch to per-CPU irq and make rxq_def useful

      As stated in the first version: "this patchset reworks the Marvell
      neta driver in order to really support its per-CPU interrupts, instead
      of faking them as SPI, and allow the use of any RX queue instead of
      the hardcoded RX queue 0 that we have currently."

      Following the review which has been done, Maxime started adding the
      CPU hotplug support. I continued his work a few weeks ago and here is
      the result.

      Since the 1st version the main change is this CPU hotplug support, in
      order to validate it I powered up and down the CPUs while performing
      iperf. I ran the tests during hours: the kernel didn't crash and the
      network interfaces were still usable. Of course it impacted the
      performance, but continuously power down and up the CPUs is not
      something we usually do.

      I also reorganized the series, the 3 first patches should go through
      the irq subsystem, whereas the 4 others should go to the network
      subsystem.

      However, there is a runtime dependency between the two parts. Patch 5
      depend on the patch 3 to be able to use the percpu irq.

      Thanks,

      Gregory

      PS: Thanks to Willy who gave me some pointers on how to deal with the
      NAPI.

      The CPU_MAP register is duplicated for each CPUs at different addresses,
      each instance being at a different address.

      However, the code so far was using CONFIG_NR_CPUS to initialise the 
CPU_MAP
      registers for each registers, while the SoCs embed at most 4 CPUs.

      This is especially an issue with multi_v7_defconfig, where CONFIG_NR_CPUS
      is currently set to 16, resulting in writes to registers that are not
      CPU_MAP.

      For some reason the name of the external interrupt controller

      blk-mq: fix deadlock when reading cpu_list

      CPU hotplug handling for blk-mq (blk_mq_queue_reinit) acquires
      all_q_mutex in blk_mq_queue_reinit_notify() and then removes sysfs
      entries by blk_mq_sysfs_unregister().  Removing sysfs entry needs to
      be blocked until the active reference of the kernfs_node to be zero.

      On the other hand, reading blk_mq_hw_sysfs_cpu sysfs entry (e.g.
      /sys/block/nullb0/mq/0/cpu_list) acquires all_q_mutex in
      blk_mq_hw_sysfs_cpus_show().

      If these happen at the same time, a deadlock can happen.  Because one
      can wait for the active reference to be zero with holding all_q_mutex,
      and the other tries to acquire all_q_mutex with holding the active
      reference.

      The reason that all_q_mutex is acquired in blk_mq_hw_sysfs_cpus_show()
      is to avoid reading an imcomplete hctx->cpumask.  Since reading sysfs
      entry for blk-mq needs to acquire q->sysfs_lock, we can avoid deadlock
      and reading an imcomplete hctx->cpumask by protecting q->sysfs_lock
      while hctx->cpumask is being updated.

      blk-mq: avoid inserting requests before establishing new mapping

      Notifier callbacks for CPU_ONLINE action can be run on the other CPU
      than the CPU which was just onlined.  So it is possible for the
      process running on the just onlined CPU to insert request and run
      hw queue before establishing new mapping which is done by
      blk_mq_queue_reinit_notify().

      This can cause a problem when the CPU has just been onlined first time
      since the request queue was initialized.  At this time ctx->index_hw
      for the CPU, which is the index in hctx->ctxs[] for this ctx, is still
      zero before blk_mq_queue_reinit_notify() is called by notifier
      callbacks for CPU_ONLINE action.

      For example, there is a single hw queue (hctx) and two CPU queues
      (ctx0 for CPU0, and ctx1 for CPU1).  Now CPU1 is just onlined and
      a request is inserted into ctx1->rq_list and set bit0 in pending
      bitmap as ctx1->index_hw is still zero.

      And then while running hw queue, flush_busy_ctxs() finds bit0 is set
      in pending bitmap and tries to retrieve requests in
      hctx->ctxs[0]->rq_list.  But htx->ctxs[0] is a pointer to ctx0, so the
      request in ctx1->rq_list is ignored.

      Fix it by ensuring that new mapping is established before onlined cpu
      starts running.

      blk-mq: fix q->mq_usage_counter access race

      CPU hotplug handling for blk-mq (blk_mq_queue_reinit) accesses
      q->mq_usage_counter while freezing all request queues in all_q_list.
      On the other hand, q->mq_usage_counter is deinitialized in
      blk_mq_free_queue() before deleting the queue from all_q_list.

      So if CPU hotplug event occurs in the window, percpu_ref_kill() is
      called with q->mq_usage_counter which has already been marked dead,
      and it triggers warning.  Fix it by deleting the queue from all_q_list
      earlier than destroying q->mq_usage_counter.

      blk-mq: fix sysfs registration/unregistration race

      There is a race between cpu hotplug handling and adding/deleting
      gendisk for blk-mq, where both are trying to register and unregister
      the same sysfs entries.

      null_add_dev
          --> blk_mq_init_queue
              --> blk_mq_init_allocated_queue
                  --> add to 'all_q_list' (*)
          --> add_disk
              --> blk_register_queue
                  --> blk_mq_register_disk (++)

      null_del_dev
          --> del_gendisk
              --> blk_unregister_queue
                  --> blk_mq_unregister_disk (--)
          --> blk_cleanup_queue
              --> blk_mq_free_queue
                  --> del from 'all_q_list' (*)

      blk_mq_queue_reinit
          --> blk_mq_sysfs_unregister (-)
          --> blk_mq_sysfs_register (+)

      While the request queue is added to 'all_q_list' (*),
      blk_mq_queue_reinit() can be called for the queue anytime by CPU
      hotplug callback.  But blk_mq_sysfs_unregister (-) and
      blk_mq_sysfs_register (+) in blk_mq_queue_reinit must not be called
      before blk_mq_register_disk (++) and after blk_mq_unregister_disk (--)
      is finished.  Because '/sys/block/*/mq/' is not exists.

      There has already been BLK_MQ_F_SYSFS_UP flag in hctx->flags which can
      be used to track these sysfs stuff, but it is only fixing this issue
      partially.

      In order to fix it completely, we just need per-queue flag instead of
      per-hctx flag with appropriate locking.  So this introduces
      q->mq_sysfs_init_done which is properly protected with all_q_mutex.

      Also, we need to ensure that blk_mq_map_swqueue() is called with
      all_q_mutex is held.  Since hctx->nr_ctx is reset temporarily and
      updated in blk_mq_map_swqueue(), so we should avoid
      blk_mq_register_hctx() seeing the temporary hctx->nr_ctx value
      in CPU hotplug handling or adding/deleting gendisk .

      svcrdma: handle rdma read with a non-zero initial page offset

      The server rdma_read_chunk_lcl() and rdma_read_chunk_frmr() functions
      were not taking into account the initial page_offset when determining
      the rdma read length.  This resulted in a read who's starting address
      and length exceeded the base/bounds of the frmr.

      The server gets an async error from the rdma device and kills the
      connection, and the client then reconnects and resends.  This repeats
      indefinitely, and the application hangs.

      Most work loads don't tickle this bug apparently, but one test hit it
      every time: building the linux kernel on a 16 core node with 'make -j
      16 O=/mnt/0' where /mnt/0 is a ramdisk mounted via NFSRDMA.

      This bug seems to only be tripped with devices having small fastreg page
      list depths.  I didn't see it with mlx4, for instance.

      mac80211: advertise support for full station state in AP mode

      This enables adding stations in unauthenticated mode, just after
      receiving the first authentication frame; which in turn allows
      sending a negative authentication reply if the station cannot be
      added.

      In addition init rate control for unassociated station only when
      it becomes associated, prior to that low rates will be used.

      cfg80211: allow changing station capabilities for unassociated stations

      Currently, cfg80211 rejects capability updates for existing entries
      and as a result it's impossible to update entries that were added
      unassociated, but that is necessary to go through the full station
      states from userspace, adding a station before authentication etc.

      Fix this by allowing updates to capabilities for stations that the
      driver (or mac80211) assigned unassociated state. Drivers setting
      the full station state support flag must use the new station type
      for proper operation.

      mac80211: allow writing TX PN in debugfs

      For certain tests, for example replay detection, it can be useful
      to be able to influence/set the PN used in outgoing packets. Make
      it possible to change the TX PN in debugfs.

      For now, this doesn't support TKIP since I haven't needed it, but
      there's no reason it couldn't be added if necessary.

      Note that this must be used very carefully: it could, for example,
      be used to make "valid replays" where the PN reuse happens on a
      different TID. This couldn't be done by an attacker since the TID
      is protected as part of the AAD.

      mac80211: don't tear down aggregation on suspend in case of wowlan->any

      In case of "any" wowlan trigger, there is no reason to tear down
      aggregations, as we want the device to continue working normally.

      Similarly, there's no reason to tear down aggregations on resume,
      as they should have been torn down on suspend if needed.
      However, since the reconfiguration flow is shared with HW restart,
      tear down aggregations on reconfiguration when we are not resuming.

      To keep things working after non-wowlan suspend, keep clearing the
      WLAN_STA_BLOCK_BA flag.

      Now, PM core supports asynchronous suspend/resume mode for devices
      during system suspend/resume, and the power state transition of one
      device may be completed in separate kernel thread. PM core ensures
      all power state transition timing dependency between devices. This
      patch enables wiphy device to suspend/resume asynchronously. This can

      mac80211: Copy tx'ed beacons to monitor mode

      When debugging wireless powersave issues on the AP side it's quite helpful
      to see our own beacons that are transmitted by the hardware/driver. 
However,
      this is not that easy since beacons don't pass through the regular TX 
queues.

      Preferably drivers would call ieee80211_tx_status also for tx'ed beacons
      but that's not always possible. Hence, just send a copy of each beacon
      generated by ieee80211_beacon_get_tim to monitor devices when they are
      getting fetched by the driver.

      Also add a HW flag IEEE80211_HW_BEACON_TX_STATUS that can be used by
      drivers to indicate that they report TX status for beacons.

      s390/boot/decompression: disable floating point in decompressor

      my gcc 5.1 used an ldgr instruction with a register != 0,2,4,6 for
      spilling/filling into a floating point register in our decompressor.

      This will cause an AFP-register data exception as the decompressor
      did not setup the additional floating point registers via cr0.
      That causes a program check loop that looked like a hang with
      one "Uncompressing Linux... " message (directly booted via kvm)
      or a loop of "Uncompressing Linux... " messages (when booted via
      zipl boot loader).

      The offending code in my build was

         48e400:       e3 c0 af ff ff 71       lay     %r12,-1(%r10)
      -->48e406:       b3 c1 00 1c             ldgr    %f1,%r12
         48e40a:       ec 6c 01 22 02 7f       clij    %r6,2,12,0x48e64e

      but gcc could do spilling into an fpr at any function. We can
      simply disable floating point support at that early stage.

      powerpc/configs: Re-enable CONFIG_SCSI_DH

      Commit 086b91d052eb ("scsi_dh: integrate into the core SCSI code")
      changed CONFIG_SCSI_DH from tristate to bool.

      Our defconfigs have CONFIG_SCSI_DH=m, which the kconfig machinery warns
      us is invalid, but instead of converting it to =y it leaves it unset.
      This means we loose the CONFIG_SCSI_DH code and everything that depends
      on it.

      So convert the values in the defconfigs to =y.

      mmc: pxamci: fix card detect with slot-gpio API

      Move pxamci to mmc slot-gpio API to fix interrupt request.

      It fixes the case where the card detection is on a gpio expander, on I2C
      for example on zylonite board. In this case, the card detect netsted
      interrupt is called from a threaded interrupt. The request_irq() fails,
      because a hard irq cannot be a nested interrupt from a threaded
      interrupt (set __setup_irq()).

      This was tested on zylonite and mioa701 boards.

      mmc: sunxi: Fix clk-delay settings

      In recent allwinner kernel sources the mmc clk-delay settings have been
      slightly tweaked, and for sun9i they are completely different then what
      we are using.

      This commit brings us in sync with what allwinner does, fixing problems
      accessing sdcards on some A33 devices (and likely others).

      For pre sun9i hardware this makes the following changes:
      -At 400Khz change the sample delay from 7 to 0 (introduced in A31 sdk)
      -At 50 Mhz change the sample delay from 5 to 4 (introduced in A23 sdk)

      This also drops the clk-delay calculation for clocks > 50 MHz, we do
      not need this as we've: mmc->f_max = 50000000, and the delays in the
      old code were not correct (at 100 MHz the delay must be a multiple of 60,
      at 200 MHz a multiple of 120).

      mmc: core: Don't return an error for CD/WP GPIOs when GPIOLIB is unset

      When CONFIG_GPIOLIB is unset, its stubs will return -ENOSYS. That means
      when the mmc core parses DT for CD/WP GPIOs via mmc_of_parse(), -ENOSYS
      becomes propagated to the caller. Typically this means that the mmc host
      driver fails to probe.

      As the CD/WP GPIOs are already treated as optional, let's extend that to
      cover the case when CONFIG_GPIOLIB is unset.

      xfrm: Let the flowcache handle its size by default.

      The xfrm flowcache size is limited by the flowcache limit
      (4096 * number of online cpus) and the xfrm garbage collector
      threshold (2 * 32768), whatever is reached first. This means
      that we can hit the garbage collector limit only on systems
      with more than 16 cpus. On such systems we simply refuse
      new allocations if we reach the limit, so new flows are dropped.
      On syslems with 16 or less cpus, we hit the flowcache limit.
      In this case, we shrink the flow cache instead of refusing new
      flows.

      We increase the xfrm garbage collector threshold to INT_MAX
      to get the same behaviour, independent of the number of cpus.

      The xfrm garbage collector threshold can still be set below
      the flowcache limit to reduce the memory usage of the flowcache.

      with small impact affecting only ITS table allocation.

       erratum 22375: only alloc 8MB table size
       erratum 24313: ignore memory access type

      The fixes are in ITS initialization and basically ignore memory access
      type and table size provided by the TYPER and BASER registers.

      irqchip/gicv3-its: Add HW revision detection and configuration

      Some GIC revisions require an individual configuration to esp. add
      workarounds for HW bugs. This patch implements generic code to parse
      the hw revision provided by an IIDR register value and runs specific
      code if hw matches. A function is added that reads the IIDR registers
      for ITS (GITS_IIDR) and then goes through a list of init functions to
      be called for specific versions. Same could be done for GICV3
      (GICD_IIDR), but there are no users yet for it.

      The patch is needed to implement workarounds for HW errata in Cavium's
      ThunderX GICV3 ITS.

      No need to read the typer register in the loop. Values do not change.

      This patch is basically a prerequisite for a follow-on patch that adds
      errata code for Cavium ThunderX. It moves the calculation of the
      number of id entries to the beginning of the function close to other
      setup values that are needed to allocate the its table. Now we have a
      central location to modify the setup parameters and the errata code
      can be implemented in a single block.

      irqchip/gicv3: Workaround for Cavium ThunderX erratum 23154

      This patch implements Cavium ThunderX erratum 23154.

      The gicv3 of ThunderX requires a modified version for reading the IAR
      status to ensure data synchronization. Since this is in the fast-path
      and called with each interrupt, runtime patching is used using jump
      label patching for smallest overhead (no-op). This is the same
      technique as used for tracepoints.

      mwifiex: fix mwifiex_rdeeprom_read()

      There were several bugs here.

      1)  The done label was in the wrong place so we didn't copy any
          information out when there was no command given.

      2)  We were using PAGE_SIZE as the size of the buffer instead of
          "PAGE_SIZE - pos".

      3)  snprintf() returns the number of characters that would have been
          printed if there were enough space.  If there was not enough space
          (and we had fixed the memory corruption bug #2) then it would result
          in an information leak when we do simple_read_from_buffer().  I've
          changed it to use scnprintf() instead.

      I also removed the initialization at the start of the function, because
      I thought it made the code a little more clear.

      airo: fix IW_AUTH_ALG_OPEN_SYSTEM

      IW_AUTH_ALG_OPEN_SYSTEM is ambiguous in set_auth for WEP as
      wpa_supplicant uses it for both no encryption and WEP open system.
      Cache the last mode set (only of these two) and use it here.

      This allows wpa_supplicant to work with unencrypted APs.

      bcma: add support for population subnodes also when build as module

      of_default_bus_match_table was not exported earlier, so it could only
      be accessed by code compiled into the kernel. A new function
      of_platform_default_populate() was added which uses
      of_default_bus_match_table and this function is also exported. This way
      it is possible to create a bus with the content of
      of_default_bus_match_table and we can remove the hacks from bcma.

      brcmfmac: Fix race condition bug when deleting p2p interface.

      When p2p device interface gets deleted by deinitialising discovery
      it will result in an event which removes the interface, but that is
      also done by delete p2p interface code. This results in race
      condition which sometimes results in lockup/crash. With this patch
      the delete device interface will wait for the event (with timeout)
      removing the possible race condition. Also on the stop device call
      from cfg80211 the deinitialisation of the discovery device should
      be avoided as it can result in a similar situation.

      We have preallocated buffer pool for Tx data. During high
      data traffic, all buffers are submitted to USB and driver needs
      to wait until one of the buffers get available for next Tx
      packet.

      "data: -ENOSR is returned" errors is expected in this case. Let's
      lower the priority of this message.

      mwifiex: avoid memsetting PCIe event buffer

      Preallocated PCIe buffer is being reused for all PCIe interface
      events. Physical address of the buffer is shared with firmware
      so that it can perform DMA on it. As event length is specified
      in the header, there should not be a problem if the buffer gets
      overwritten.
      We will save some cycles by avoiding memset everytime while
      submitting the buffer to firmware.

      This NULL pointer dereference is observed during suspend resume
      stress test. All pending commands are cancelled when system goes
      into suspend state. There a corner case in which host may receive
      response for last scan command after this and try to trigger extra

      The issue is fixed by adding a NULL check to skip that extra scan.

      mwifiex: fix driver init failure under memory pressure

      64k Tx and Rx buffers are allocated during driver initialization
      for SDIO level data aggregations. When host is under memory
      pressure situation, kzalloc() request for 64k may fail.

      We will try allocating 32k buffers and disable our rx single port
      aggreagation feature in this situation.

      If the allocation still fails, we will disable our sdio multport
      aggregation feature as well. In this way, we will transmit and
      receive packets one by one, thus reduce the demand for big
      memory.

      brcmfmac: correct detection of p2pdev interface event

      The p2pdev interface is setup in firmware resulting in a interface
      event. This event has role and no-if flag. When role is p2p client
      and no-if flag is set it indicates that this is the p2pdev interface.
      This info is used in handling the event and adding interface in the
      driver.

      brcmfmac: only call brcmf_cfg80211_detach() when attach was successful

      In brcmf_bus_start() the function brcmf_cfg80211_attach() is called which
      may fail. If this happens we should not call brcmf_cfg80211_detach() in
      the failure path as it will result in NULL pointer dereference:

      ARM: dts: Fix wrong clock binding for sysmmu_fimd1_1 on exynos5420

      The sysmmu_fimd1_1 should bind the clock CLK_SMMU_FIMD1M1, not the clock
      CLK_SMMU_FIMD1M0. CLK_SMMU_FIMD1M0 is a clock for the sysmmu_fimd1_0.

      This wrong clock binding causes the problem that is blocked in iommu_map
      function when IOMMU is enabled and exynos-drm driver tries to allocate
      buffer via DMA mapping API on Odroid-XU3 board.

      net: help compiler generate better code in eth_get_headlen

      Noticed that the compiler (gcc version 4.8.5 20150623 (Red Hat 4.8.5-4) 
(GCC))
      generated suboptimal assembler code in eth_get_headlen().

      This early return coding style is usually not an issue, on super scalar 
CPUs,
      but the compiler choose to put the return statement after this very 
unlikely
      branch, thus creating larger jump down to the likely code path.

      Performance wise, I could measure slightly less L1-icache-load-misses
      and less branch-misses, and an improvement of 1 nanosec with an 
IP-forwarding

      tcp: Fix CWV being too strict on thin streams

      Application limited streams such as thin streams, that transmit small
      amounts of payload in relatively few packets per RTT, can be prevented
      from growing the CWND when in congestion avoidance. This leads to
      increased sojourn times for data segments in streams that often transmit
      time-dependent data.

      Currently, a connection is considered CWND limited only after having
      successfully transmitted at least one packet with new data, while at the
      same time failing to transmit some unsent data from the output queue
      because the CWND is full. Applications that produce small amounts of
      data may be left in a state where it is never considered to be CWND
      limited, because all unsent data is successfully transmitted each time
      an incoming ACK opens up for more data to be transmitted in the send
      window.

      Fix by always testing whether the CWND is fully used after successful
      packet transmissions, such that a connection is considered CWND limited
      whenever the CWND has been filled. This is the correct behavior as
      specified in RFC2861 (section 3.1).

      net: irda: pxaficp_ir: use sched_clock() for time management

      Instead of using directly the OS timer through direct register access,
      use the standard sched_clock(), which will end up in OSCR reading
      anyway.

      This is a first step for direct access register removal and machine
      specific code removal from this driver.

      This commit changes the behavior, as previously the minimum turnaround
      time was counted in 76ns steps, while with this patch it is counted in
      microsecond steps. The strictly equal formula would have been :
            while ((sched_clock() - si->last_clk) * 76 < mtt)

      net/ibm/emac: bump version numbers for correct work with ethtool

      The size of the MAC register dump used to be the size specified by the
      reg property in the device tree.  Userland has no good way of finding
      out that size, and it was not specified consistently for each MAC type,
      so ethtool would end up printing junk at the end of the register dump
      if the device tree didn't match the size it assumed.

      Using the new version numbers indicates unambiguously that the size of
      the MAC register dump is dependent only on the MAC type.

      net/mlx5_core: New init and exit flow for mlx5_core

      In the new flow, we separate the pci initialization and teardown from the
      initialization and teardown of the other resources.

      init_one calls mlx5_pci_init that handles the pci resources 
initialization.
      It then calls mlx5_load_one to initialize the remainder of the resources.

      When removing a device, remove_one is invoked. However, now remove_one
      calls mlx5_unload_one to free all the resources except the pci resources.
      When mlx5_unload_one returns, mlx5_pci_close is called to free the pci
      resources.

      The above separation will allow us to implement the pci error handlers and
      suspend and resume callbacks.

      tcp: avoid reorders for TFO passive connections

      We found that a TCP Fast Open passive connection was vulnerable
      to reorders, as the exchange might look like

      [1] C -> S S <FO ...> <request>
      [2] S -> C S. ack request <options>
      [3] S -> C . <answer>

      packets [2] and [3] can be generated at almost the same time.

      If C receives the 3rd packet before the 2nd, it will drop it as
      the socket is in SYN_SENT state and expects a SYNACK.

      S will have to retransmit the answer.

      Current OOO avoidance in linux is defeated because SYNACK
      packets are attached to the LISTEN socket, while DATA packets
      are attached to the children. They might be sent by different cpus,
      and different TX queues might be selected.

      It turns out that for TFO, we created a child, which is a
      full blown socket in TCP_SYN_RECV state, and we simply can attach
      the SYNACK packet to this socket.

      This means that at the time tcp_sendmsg() pushes DATA packet,
      skb->ooo_okay will be set iff the SYNACK packet had been sent
      and TX completed.

      This removes the reorder source at the host level.

      We also removed the export of tcp_try_fastopen(), as it is no
      longer called from IPv6.

      sctp: Prevent soft lockup when sctp_accept() is called during a timeout 
event

      A case can occur when sctp_accept() is called by the user during
      a heartbeat timeout event after the 4-way handshake.  Since
      sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the
      bh_sock_lock in sctp_generate_heartbeat_event() will be taken with
      the listening socket but released with the new association socket.
      The result is a deadlock on any future attempts to take the listening
      socket lock.

      Note that this race can occur with other SCTP timeouts that take
      the bh_lock_sock() in the event sctp_accept() is called.

      Intel Wired LAN Driver Updates 2015-09-28

      This series contains updates to i40e, i40evf and igb to resolve issues
      seen and reported by Red Hat.

      Kiran moves i40e_get_head() in preparation for the refactor of the Tx
      timeout logic, so that it can be used in other areas of the driver.
      Refactored the driver timeout logic by issuing a writeback request via
      a software interrupt to the hardware the first time the driver detects
      a hang.  This was due to the driver being too aggressive in resetting a
      hung queue.

      Shannon adds the GRE protocol to the transmit checksum encoding.

      Anjali fixes an issue of forcing writeback too often, which caused us to
      not benefit from NAPI.  We now disable force writeback in the clean
      routine for X710 and XL710 adapters.  The X722 adapters do not enable
      interrupt to force a writeback and benefit from WB_ON_ITR and so force
      WB is left enabled for those adapters.  Fixed a possible deadlock issue
      where sync_vsi_filters() can be called directly under RTNL or through
      the timer subtask without RTNL.  So update the flow to see if we are
      already under RTNL before trying to grab it.

      Stefan Assmann provides a fix for igb where SR-IOV was not getting
      enabled properly and we ran into a NULL pointer if the max_vfs module
      parameter is specified.  This is prevented by setting the
      IGB_FLAG_HAS_MSIX bit before calling igb_probe_vfs().

      v2: added "i40e: Fix for recursive RTNL lock during PROMISC change" patch
          to the series, as it resolves another issues seen and reported by
          Red Hat.

      igb_init_queue_configuration()
      igb_init_interrupt_scheme()

      This results in adapter->flags not having the IGB_FLAG_HAS_MSIX bit set
      during igb_probe_vfs()->igb_enable_sriov(). Therefore SR-IOV does not
      get enabled properly and we run into a NULL pointer if the max_vfs
      module parameter is specified (adapter->vf_data does not get allocated,
      crash on accessing the structure).

      i40e: Fix for recursive RTNL lock during PROMISC change

      The sync_vsi_filters function can be called directly under RTNL
      or through the timer subtask without one. This was causing a deadlock.

      If sync_vsi_filters is called from a thread which held the lock,
      and in another thread the PROMISC setting got changed we would
      be executing the PROMISC change in the thread which already held
      the lock alongside the other filter update. The PROMISC change
      requires a reset if we are on a VEB, which requires it to be called
      under RTNL.

      Earlier the driver would call reset for PROMISC change without
      checking if we were already under RTNL and would try to grab it
      causing a deadlock. This patch changes the flow to see if we are
      already under RTNL before trying to grab it.

      i40e: Fix RS bit update in Tx path and disable force WB workaround

      This patch fixes the issue of forcing WB too often causing us to not
      benefit from NAPI.

      Without this patch we were forcing WB/arming interrupt too often taking
      away the benefits of NAPI and causing a performance impact.

      With this patch we disable force WB in the clean routine for X710
      and XL710 adapters. X722 adapters do not enable interrupt to force
      a WB and benefit from WB_ON_ITR and hence force WB is left enabled
      for those adapters.
      For XL710 and X710 adapters if we have less than 4 packets pending
      a software Interrupt triggered from service task will force a WB.

      This patch also changes the conditions for setting RS bit as described
      in code comments. This optimizes when the HW does a tail bump and when
      it does a WB. It also optimizes when we do a wmb.

      i40e/i40evf: refactor tx timeout logic

      This patch modifies the driver timeout logic by issuing a writeback
      request via a software interrupt to the hardware the first time the
      driver detects a hang. The driver was too aggressive in resetting a hung
      queue, so back that off by removing logic to down the netdevice after
      too many hangs, and move the function to the service task.

      perf tools: Enable event_config terms to tracepoint events

      This patch enables config terms for tracepoint perf events. Valid terms
      for tracepoint events are 'call-graph' and 'stack-size', so we can use
      different callgraph settings for each event and eliminate unnecessary
      overhead.

      Here is an example for using different call-graph config for each
      tracepoint.

        $ perf record -e syscalls:sys_enter_write/call-graph=fp/
                      -e syscalls:sys_exit_write/call-graph=no/

      perf tools: Show proper error message for wrong terms of hw/sw events

      Show proper error message and show valid terms when wrong config terms
      is specified for hw/sw type perf events.

      This patch makes the original error format function formats_error_string()
      more generic, which only outputs the static config terms for hw/sw perf
      events, and prepends pmu formats for pmu events.

      Before this patch:

        $ perf record -e 'cpu-clock/freqx=200/' -a sleep 1
        invalid or unsupported event: 'cpu-clock/freqx=200/'
        Run 'perf list' for a list of valid events

         usage: perf record [<options>] [<command>]
            or: perf record [<options>] -- <command> [<options>]

            -e, --event <event>   event selector. use 'perf list' to list 
available events

      After this patch:

        $ perf record -e 'cpu-clock/freqx=200/' -a sleep 1
        event syntax error: 'cpu-clock/freqx=200/'
                                       \___ unknown term

        valid terms: 
config,config1,config2,name,period,freq,branch_type,time,call-graph,stack-size

        Run 'perf list' for a list of valid events

         usage: perf record [<options>] [<command>]
            or: perf record [<options>] -- <command> [<options>]

            -e, --event <event>   event selector. use 'perf list' to list

      perf tools: Adds the config_term callback for different type events

      Currently, function config_term() is used for checking config terms of
      all types of events, while unknown terms is not reported as an error
      because pmu events have valid terms in sysfs.

      But this is wrong when unknown terms are specificed to hw/sw events.
      This patch Adds the config_term callback so we can use separate check
      routines for each type of events.

      perf intel-pt: Add mispred-all config option to aid use with autofdo

      autofdo incorrectly expects branch flags to include either mispred or
      predicted.  In fact mispred = predicted = 0 is valid and means the flags
      are not supported, which they aren't by Intel PT.

      To make autofdo work, add a config option which will cause Intel PT
      decoder to set the mispred flag on all branches.

      Below is an example of using Intel PT with autofdo.  The example is
      also added to the Intel PT documentation.  It requires autofdo
      (https://github.com/google/autofdo) and gcc version 5.  The bubble
      sort example is from the AutoFDO tutorial 
(https://gcc.gnu.org/wiki/AutoFDO/Tutorial)
      amended to take the number of elements as a parameter.

        $ gcc-5 -O3 sort.c -o sort_optimized
        $ ./sort_optimized 30000
        Bubble sorting array of 30000 elements

      perf inject: Add --strip option to strip out non-synthesized events

      Add a new option --strip which is used with --itrace to strip out
      non-synthesized events.  This results in a perf.data file that is
      simpler for external tools to parse.  In particular, this can be used to
      prepare a perf.data file for consumption by autofdo.

      A subsequent patch makes a change to Intel PT also to enable use with
      autofdo and gives an example of that use.

      perf inject: Remove more aux-related stuff when processing instruction 
traces

      perf inject can process instruction traces (using the --itrace option)
      which removes aux-related events and replaces them with the requested
      synthesized events.

      However there are still some leftovers, namely PERF_RECORD_ITRACE_START
      events and the original evsel (selected event) e.g. intel_pt//

      For the sake of completeness, remove them too.

      perf script: Make scripting_max_stack value allow for synthesized 
callchains

      perf script has a setting to set the maximum stack depth when processing
      callchains.  The setting defaults to the hard-coded maximum definition
      PERF_MAX_STACK_DEPTH which is 127.

      It is possible, when processing instruction traces, to synthesize
      callchains.  Synthesized callchains do not have the kernel size
      limitation and are whatever size the user requests, although validation
      presently prevents the user requested a value greater that 1024.  The
      default value is 16.

      To allow for synthesized callchains, make the scripting_max_stack value
      at least the same size as the synthesized callchain size.

      perf intel-pt: Support generating branch stack

      Add support for generating branch stack context for PT samples.  The
      decoder reports a configurable number of branches as branch context for
      each sample. Internally it keeps track of them by using a simple sliding
      window.  We also flush the last branch buffer on each sample to avoid
      overlapping intervals.

      This is useful for:

      - Reporting accurate basic block edge frequencies through the perf
        report branch view
      - Using with --branch-history to get the wider context of samples
      - Other users of LBRs

      Also the Documentation is updated.

      Examples:

        Record with Intel PT:

                perf record -e intel_pt//u ls

        Branch stacks are used by default if synthesized so:

                perf report --itrace=ile

        is the same as:

                perf report --itrace=ile -b

        Branch history can be requested also:

                perf report --itrace=igle --branch-history

      A non-synthesized event might not have a branch stack if branch stacks

      An example of that is when Intel PT records sched_switch events for
      decoding purposes.  Those sched_switch events do not have branch stacks
      even though the Intel PT decoder may be synthesizing other events that
      do due to the itrace options.

      perf intel-pt: Fix potential loop forever

      TSC packets contain only 7 bytes of TSC.  The 8th byte is assumed to
      change so infrequently that its value can be inferred.  However the
      logic must cater for a 7 byte wraparound, which it does by adding 1 to
      the top byte.

      The existing code was doing that with a while loop even though the
      addition should only need to be done once.  That logic won't work (will
      loop forever) if TSC wraps around at the 8th byte.  Theoretically that
      would take at least 10 years, unless something else went wrong.

      And what else could go wrong.  Well, if the chunks of trace data are
      processed out of order, it will make it look like the 7-byte TSC has
      gone backwards (i.e. wrapped).  If that happens 256 times then stuck in
      the while loop it will be.

      Fix that by getting rid of the unnecessary while loop.

        $ perf record -e intel_pt//u uname
        $ perf report --stdio --itrace=ige

      However perf report's callgraph option gets extra validation, so:

        $ perf report --stdio --itrace=ige -gflat
        Error:
        Selected -g or --branch-history but no callchain data. Did
        you call 'perf record' without -g?
        # To display the perf.data header info,
        # please use --header/--header-only options.
        #

      Fix the validation to know about instruction tracing options so
      above command works.

      A side-effect of the change is that the default option to
      accumulate the callchain of child functions comes into force.
      To get the previous behaviour the --no-children option can be
      used e.g.

             $ perf report --stdio --itrace=ige -gflat --no-children

      perf auxtrace: Fix 'instructions' period of zero

      Instruction tracing options (i.e. --itrace) include an option for
      sampling instructions at an arbitrary period. e.g.

        --itrace=i10us

      means make an 'instructions' sample for every 10us of trace.

      Currently the logic does not distinguish between a period of
      zero and no period being specified at all, so it gets treated
      as the default period which is 100000.  That doesn't really
      make sense.

      Fix it so that zero period is accepted and treated as meaning
      "as often as possible".

      In the case of Intel PT that is the same as a period of 1 and
      a unit of 'instructions' (i.e. --itrace=i1i).

  Date:   Wed Sep 23 12:33:58 2015 +0200

      tools build: Add fixdep dependency helper

      For dependency tracking we currently use targets that fall out of the
      gcc -MD command. We store this info in the .cmd file and include as
      makefile during the build.

      This format put object as target and all the c and header files as
      dependencies, like:

        util/abspath.o: util/abspath.c /usr/include/stdc-predef.h util/cache.h \
         /usr/include/bits/wordsize.h /usr/include/gnu/stubs.h \
         ...

      If any of those dependency header files (krava.h below) is removed the
      build fails on:

        make[1]: *** No rule to make target 'krava.h', needed by 'inc.o'.  Stop.

      This patch adds fixdep helper, that is used by kbuild to alter the shape
      of the object dependencies like:

        source_util/abspath.o := util/abspath.c

        deps_util/abspath.o := \
          /usr/include/stdc-predef.h \
          util/cache.h \
          ...

        util/abspath.o: $(deps_util/abspath.o)

        $(deps_util/abspath.o):

      With this format the header removal won't make the build fail, because
      it'll be picked up by the last empty target defined for each header.

      As previously mentioned the fixdep tool is taken from kbuild. It's not
      complete backport, only the part that alters the standard dependency
      info was taken, the part that adds the CONFIG_* dependency logic will be
      probably taken later on.

      error message hint ('Hint:' line). The error hint rediscovers
      mountpoints, but it could be different from what we actually
      used in tracing path.

      Before we'd display debugfs mount even though tracefs was used:
        $ perf record -e sched:sched_krava ls
        event syntax error: 'sched:sched_krava'

      drm/i915: Consider HW CSB write pointer before resetting the sw read 
pointer

      A previous commit resets the Context Status Buffer (CSB) read pointer in
      ring init
          commit c0a03a2e4c4e ("drm/i915: Reset CSB read pointer in ring init")

      This is generally correct, but this pointer is not reset after
      suspend/resume in some platforms (cht). In this case, the driver should
      read the register value instead of resetting the sw read counter to 0.
      Otherwise we process old events, leading to unwanted pre-emptions or
      something worse.

      But in other platforms (bdw) and also during GPU reset or power up, the
      CSBWP is reset to 0x7 (an invalid number), and in this case the read
      pointer should be set to 5 (the interrupt code will increment this
      counter one more time, and will start reading from CSB[0]).

      v2: When the CSB registers are reset, the read pointer needs to be set
      to 5, otherwise the first write (CSB[0]) won't be read (Mika).
      Replace magic numbers with GEN8_CSB_ENTRIES (6) and GEN8_CSB_PTR_MASK

      x86/xen: Support kexec/kdump in HVM guests by doing a soft reset

      Currently there is a number of issues preventing PVHVM Xen guests from
      doing successful kexec/kdump:

        - Bound event channels.
        - Registered vcpu_info.
        - PIRQ/emuirq mappings.
        - shared_info frame after XENMAPSPACE_shared_info operation.
        - Active grant mappings.

      Basically, newly booted kernel stumbles upon already set up Xen
      interfaces and there is no way to reestablish them. In Xen-4.7 a new
      feature called 'soft reset' is coming. A guest performing kexec/kdump
      operation is supposed to call SCHEDOP_shutdown hypercall with
      SHUTDOWN_soft_reset reason before jumping to new kernel. Hypervisor
      (with some help from toolstack) will do full domain cleanup (but
      keeping its memory and vCPU contexts intact) returning the guest to
      the state it had when it was first booted and thus allowing it to
      start over.

      Doing SHUTDOWN_soft_reset on Xen hypervisors which don't support it is
      probably OK as by default all unknown shutdown reasons cause domain
      destroy with a message in toolstack log: 'Unknown shutdown reason code
      5. Destroying domain.'  which gives a clue to what the problem is and
      eliminates false expectations.

      xen/x86: Don't try to write syscall-related MSRs for PV guests

      For PV guests these registers are set up by hypervisor and thus
      should not be written by the guest. The comment in xen_write_msr_safe()
      says so but we still write the MSRs, causing the hypervisor to
      print a warning.

      xen: use correct type for HYPERVISOR_memory_op()

      HYPERVISOR_memory_op() is defined to return an "int" value. This is
      wrong, as the Xen hypervisor will return "long".

      The sub-function XENMEM_maximum_reservation returns the maximum
      number of pages for the current domain. An int will overflow for a
      domain configured with 8TB of memory or more.

      Correct this by using the correct type.

      Revert "KVM: x86: zero kvmclock_offset when vcpu0 initializes kvmclock 
system MSR"

      Shifting pvclock_vcpu_time_info.system_time on write to KVM system time
      MSR is a change of ABI.  Probably only 2.6.16 based SLES 10 breaks due
      to its custom enhancements to kvmclock, but KVM never declared the MSR
      only for one-shot initialization.  (Doc says that only one write is
      needed.)

      This reverts commit b7e60c5aedd2b63f16ef06fde4f81ca032211bc5.

      watchdog: bcm2835: Fix poweroff behaviour

      Currently poweroff/halt results in a reboot on the Raspberry Pi.
      The firmware uses the RSTS register to know which partiton to
      boot from. The partiton value is spread into bits
      0, 2, 4, 6, 8, 10. Partiton 63 is a special partition used by
      the firmware to indicate halt.

      The firmware made this change in 19 Aug 2013 and was matched

      x86/mce: Don't clear shared banks on Intel when offlining CPUs

      It is not safe to clear global MCi_CTL banks during CPU offline
      or suspend/resume operations. These MSRs are either
      thread-scoped (meaning private to a thread), or core-scoped
      (private to threads in that core only), or with a socket scope:
      visible and controllable from all threads in the socket.

      When we offline a single CPU, clearing those MCi_CTL bits will
      stop signaling for all the shared, i.e., socket-wide resources,
      such as LLC, iMC, etc.

      In addition, it might be possible to compromise the integrity of
      an Intel Secure Guard eXtentions (SGX) system if the attacker
      has control of the host system and is able to inject errors
      which would be otherwise ignored when MCi_CTL bits are cleared.

      Hence on SGX enabled systems, if MCi_CTL is cleared, SGX gets
      disabled.

      My first attempt was to remove the intel_prepare_ddi, but Daniel had 
pointed out
      this is really needed to restore those registers values. And Imre pointed 
out
      that this case was without the flag protection and this was actually 
where things
      were going bad. So I've just checked and this indeed solves my issue.

      m68k: Define asmlinkage_protect

      Make sure the compiler does not modify arguments of syscall functions.
      This can happen if the compiler generates a tailcall to another
      function.  For example, without asmlinkage_protect sys_openat is compiled
      into this function:

      sys_openat:
        clr.l %d0
        move.w 18(%sp),%d0
        move.l %d0,16(%sp)
        jbra do_sys_open

      Note how the fourth argument is modified in place, modifying the register
      %d4 that gets restored from this stack slot when the function returns to
      user-space.  The caller may expect the register to be unmodified across
      system calls.

      Input: serio - fix blocking of parport

      If parkbd_allocate_serio() fails to allocate memory we are releasing the
      parport but we missed unregistering the device. As a result this device
      with exclusive access to that parport remains registered. And no other
      device will be able to use that parport even though this driver has
      failed to load.

      ldpc is not configured for fixed rates. This blocks auto rate vs fixed
      rate performance comparison. Since firmware is considering ldpc vdev
      param for fixed rate selection, it has to be configured to enable ldpc

      ath: use PRI value given by spec for fixed PRI

      PRI value is used as divider when DFS detector analyzes candidate
      radar pulses.
      If PRI deviation is big from its origin PRI, DFS detector could miss
      valid radar reports since HW often misses detecting radar pulses and
      causes long interval value of pulses.

      For instance from practical results, if runtime PRI is calculated as
      1431 for fixed PRI value of 1428 and delta timestamp logs 15719,
      the modular remainder will be 1409 and the delta between the remainder
      and runtime PRI is 22 that is bigger than PRI tolerance which is 16.
      As a result this radar report will be ignored even though it's valid.

      By using spec defined PRI for fixed PRI, we can correct this error.

      ath: fix incorrect PPB on JAPAN chirp radar

      The number of pulses per burst on Japan chirp radar is
      between 1 and 3. The previous value, 20, is representing
      number of bursts, but since current DFS detector is using
      pulse detection other than bursts, use the pulse number
      for correct radar detection.
      Also using the highest number helps to avoid false detection.

      MIPS: Initialise MAARs on secondary CPUs

      MAARs should be initialised on each CPU (or rather, core) in the system
      in order to achieve consistent behaviour & performance. Previously they
      have only been initialised on the boot CPU which leads to performance
      problems if tasks are later scheduled on a secondary CPU, particularly
      if those tasks make use of unaligned vector accesses where some CPUs
      don't handle any cases in hardware for non-speculative memory regions.
      Fix this by recording the MAAR configuration from the boot CPU and
      applying it to secondary CPUs as part of their bringup.

      MIPS: print MAAR configuration during boot

      Verifying that the MAAR configuration is as expected is useful when
      debugging the performance of a system. Print out the memory regions
      configured via MAAR along with their attributes.

      MIPS: mm: compile maar_init unconditionally

      maar_init was previously only compiled when CONFIG_NEED_MULTIPLE_NODES
      was not set, which has been fine since it is only called from the
      standard implementation of mem_init which has the same condition. In
      preparation for calling it from the SMP startup code on secondary CPUs,
      move maar_init outside of the #ifndef such that it is always compiled.

      irqchip: mips-gic: Fix pending & mask reads for MIPS64 with 32b GIC.

      gic_handle_shared_int reads the GIC interrupt pending & mask registers
      directly into a bitmap, which is defined as an array of unsigned longs.
      The GIC pending registers may be 32 bits wide if the CM is older than
      CM3, regardless of the bit width of the CPU, but for MIPS64 kernels
      the unsigned longs in the bitmap will be 64 bits wide. In this case we
      need to perform 2 x 32 bit reads per 64 bit unsigned long in order to
      avoid missing interrupts.

      MIPS: CM: Provide a function to map from CPU to VP ID.

      The VP ID of a given CPU may not match up with the CPU number used by
      Linux. For example, if the width of the VP part of the VP ID is wider
      than log2(number of VPs per core) and the system has multiple cores then
      this will be the case. Alternatively, if a pre-r6 system implements the
      MT ASE with multiple VPEs per core and Linux is built without support
      for the MT ASE then the numbers won't match up either. Provide a
      function to convert from CPU number to VP ID.

      ====================
      vxlan: support both IPv4 and IPv6 sockets

      Note: this needs net merged into net-next in order to apply.

      It's currently not easy enough to work with metadata based vxlan tunnels. 
In
      particular, it's necessary to create separate network interfaces for IPv4
      and IPv6 tunneling. Assigning an IPv6 address to an IPv4 interface is
      allowed yet won't do what's expected. With route based tunneling, one has 
to
      pay attention to use the vxlan interface opened with the correct family.
      Other users of this (openvswitch) would need to always create two vxlan
      interfaces.

      Furthermore, there's no sane API for creating an IPv6 vxlan metadata based
      interface.

      This patchset simplifies this by opening both IPv4 and IPv6 socket if the
      vxlan interface has the metadata flag (IFLA_VXLAN_COLLECT_METADATA) set.
      Assignment of addresses etc. works as expected after this.

vxlan_sock.

      8139cp: Fix GSO MSS handling

      When fixing the TSO support I noticed we just mask ->gso_size with the
      MSSMask value and don't care about the consequences.

      Provide a .ndo_features_check() method which drops the NETIF_F_TSO
      feature for any skb which would exceed the maximum, and thus forces it
      to be segmented by software.

      Then we can stop the masking in cp_start_xmit(), and just WARN if the
      maximum is exceeded, which should now never happen.

      Finally, Francois Romieu noticed that we didn't even have the right
      value for MSSMask anyway; it should be 0x7ff (11 bits) not 0xfff.

        Also included are some recent >= v4.2 regression bug-fixes.  The most
        notable is a RCU conversion regression for SPC-3 PR registrations, and
        recent removal of obsolete RFC-3720 markers that introduced a login
        regression bug with MSFT iSCSI initiators.

        Thanks to everyone who has been testing + reporting bugs for v4.x"

      ath10k: fix DMA related firmware crashes on multiple devices

      Some platforms really don't like DMA bursts of 256 bytes, and this
      causes the firmware to crash when sending beacons.
      Also, changing this based on the firmware version does not seem to make
      much sense, so use 128 bytes for all versions.

      ath9k inserts padding between the 802.11 header and the data area (to

      tools/power turbostat: SKL: Adjust for TSC difference from base frequency

      On a Skylake with 1500MHz base frequency,
      the TSC runs at 1512MHz.

      This is because the TSC is no longer in the n*100 MHz BCLK domain,
      but is now in the m*24MHz crystal clock domain. (24 MHz * 63 = 1512 MHz)

      This adds error to several calculations in turbostat,
      unless the TSC sample sizes are adjusted for this difference.

      Note that calculations in the time domain are immune
      from this issue, as the timing sub-system has already
      calibrated the TSC against a known wall clock.

      AVG_MHz = APERF_delta/measurement_interval

        need no adjustment.  APERF_delta is in the BCLK domain,
        and measurement_interval is in the time domain.

      TSC_MHz  =  TSC_delta/measurement_interval

        needs no adjustment -- as we really do want to report
        the actual measured TSC delta here, and measurement_interval
        is in the accurate time domain.

      %Busy = MPERF_delta/TSC_delta

        needs adjustment to use TSC_BCLK_DOMAIN_delta.
        TSC_BCLK_DOMAIN_delta = TSC_delta * base_hz / tsc_hz

      Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval

        need adjustment as above.

      No other metrics in turbostat need to be adjusted.

      Before:

           CPU Avg_MHz   %Busy Bzy_MHz TSC_MHz
             -     550   24.84    2216    1512
             0    2191   98.73    2219    1514
             2       0    0.01    2130    1512
             1       9    0.43    2016    1512
             3       2    0.08    2016    1512

      After:

           CPU Avg_MHz   %Busy Bzy_MHz TSC_MHz
             -     550   25.05    2198    1512
             0    2190   99.62    2199    1512
             2       0    0.01    2152    1512
             1       9    0.46    2000    1512
             3       2    0.10    2000    1512

      Note that in this example, the "Before" Bzy_MHz
      was reported as exceeding the 2200 max turbo rate.
      Also, even a pinned spin loop would not be reported
      as over 99% busy.

      tools/power turbostat: KNL workaround for %Busy and Avg_MHz

      KNL increments APERF and MPERF every 1024 clocks.
      This is compliant with the architecture specification,
      which requires that only the ratio of APERF/MPERF need be valid.

      However, turbostat takes advantage of the fact that these
      two MSRs increment every un-halted clock
      at the actual and base frequency:

      AVG_MHz = APERF_delta/measurement_interval

      %Busy = MPERF_delta/TSC_delta

      tools/power turbostat: IVB Xeon: fix --debug regression

      Staring in Linux-4.3-rc1,
      commit 6fb3143b561c ("tools/power turbostat: dump CONFIG_TDP")
      touches MSR 0x648, which is not supported on IVB-Xeon.
      This results in "turbostat --debug" exiting on those systems:

      turbostat: /dev/cpu/2/msr offset 0x648 read failed: Input/output error

      Remove IVB-Xeon from the list of machines supporting with that MSR.

      IB/ipoib: increase the max mcast backlog queue

      When performing sendonly joins, we queue the packets that trigger
      the join until the join completes.  This may take on the order of
      hundreds of milliseconds.  It is easy to have many more than three
      packets come in during that time.  Expand the maximum queue depth
      in order to try and prevent dropped packets during the time it
      takes to join the multicast group.

      ACPI, PCI, irq: Do not share PCI IRQ with ISA IRQ

      Avoid IRQs occupied by ISA IRQs when allocating IRQs for PCI link devices,
      otherwise it may cause interrupt storm due to incompatible pin attributes.

      This issue was triggered on a KVM virtual machine, which
       1) uses IRQ9 for SCI in high level mode.
       2) defines an PCI interrupt link device (LNKS) with IRQ9 as the only
          possible irq.
       3) has an PCI device referring to link device LNKS.
      So it causes interrupt storm when enabling the PCI device because PCI IRQ
      works in low level mode.

      When query handler is not found, "result" is actually stil 0, and
      "struct acpi_ec_query" is not NULL, so the deletion code of

      dccp/tcp: constify listener sock

      Another patch bomb to prepare lockless TCP/DCCP LISTEN handling.

      SYNACK retransmits are built and sent without listener socket
      being locked. Soon, initial SYNACK packets will have same property.

      This series makes sure we did not something wrong with this model,
      by adding a const qualifier in all the paths taken from synack building
      and transmit, for IPv4/IPv6 and TCP/dccp.

      The only potential problem was the rewrite of ecn bits for connections
      with DCTCP as congestion module, but this was a very minor one.

      We better make sure no field is written.

      There is one exception : Since SYNACK packets are attached to the listener
      at this moment (or SYN_RECV child in case of Fast Open),
      sock_wmalloc() needs to update sk->sk_wmem_alloc, but this is done using

      IB/ipoib: Make sendonly multicast joins create the mcast group

      Since IPoIB should, as much as possible, emulate how multicast
      sends work on Ethernet for regular TCP/IP apps, there should be
      no requirement to subscribe to a multicast group before your
      sends are properly sent.  However, due to the difference in how
      multicast is handled on InfiniBand, we must join the appropriate
      multicast group before we can send to it.  Previously we tried
      not to trigger the auto-create feature of the subnet manager when
      doing this because we didn't have tracking of these sendonly
      groups and the auto-creation might never get undone.  The previous
      patch added timing to these sendonly joins and allows us to
      leave them after a reasonable idle expiration time.  So supply
      all of the information needed to auto-create group.

      EDAC: Fix sysfs dimm_label store operation

      Sysfs "dimm_label" and "chX_dimm_label" nodes have the following issues
      in their store operation:

       1) A newline-terminated input string causes redundant newlines:

        # echo "test" > /sys/bus/mc0/devices/dimm0/dimm_label
        # cat  /sys/bus/mc0/devices/dimm0/dimm_label
        test

        #  od -bc /sys/bus/mc0/devices/dimm0/dimm_label
        0000000 164 145 163 164 012 012
                  t   e   s   t  \n  \n
        0000006

       2) The original label string (31 characters) cannot be stored due to
          an improper size check:

        # echo "CPU_SrcID#0_Ha#0_Chan#0_DIMM#0" > 
/sys/bus/mc0/devices/dimm0/dimm_label
        # cat /sys/bus/mc0/devices/dimm0/dimm_label

        # od -bc /sys/bus/mc0/devices/dimm0/dimm_label
         0000000 012 012
                  \n  \n
         0000002

       3) An input string longer than the buffer size results a wrong label
          info as it allows a retry with the remaining string:

        # echo "CPU_SrcID#0_Ha#0_Chan#0_DIMM#0_TEST" > 
/sys/bus/mc0/devices/dimm0/dimm_label
        # cat  /sys/bus/mc0/devices/dimm0/dimm_label
        _TEST

      Fix these issues by making the following changes:
       1) Replace a newline character at the end by setting a null. It also
          assures that the string is null-terminated in the label buffer.
       2) Check the label buffer size with 'sizeof(dimm->label)'.
       3) Fail a request if its string exceeds the label buffer size.

      EDAC: Fix sysfs dimm_label show operation

      After

        7d375bffa524 ("sb_edac: Fix support for systems with two home agents 
per socket")

      sysfs "dimm_label" and "chX_dimm_label" show their label string without a
      newline "\n" at the end.

        [root@orange ~]# cat /sys/bus/mc0/devices/dimm0/dimm_label
        CPU_SrcID#0_Ha#0_Chan#0_DIMM#0[root@orange ~]#

        [root@orange ~]# cat 
/sys/devices/system/edac/mc/mc0/csrow0/ch0_dimm_label
        CPU_SrcID#0_Ha#0_Chan#0_DIMM#0[root@orange ~]#

      The label strings now have 31 characters, which are the same as
      EDAC_MC_LABEL_LEN. Since the snprintf()s in channel_dimm_label_show()
      and dimmdev_label_show() limit the whole length by EDAC_MC_LABEL_LEN,
      the newline in the format "%s\n" is ignored.

        [root@orange ~]# od -bc /sys/bus/mc0/devices/dimm0/dimm_label
        0000000 103 120 125 137 123 162 143 111 104 043 060 137 110 141 043 060
                  C   P   U   _   S   r   c   I   D   #   0   _   H   a   #   0
        0000020 137 103 150 141 156 043 060 137 104 111 115 115 043 060 000
                  _   C   h   a   n   #   0   _   D   I   M   M   #   0  \0
        0000037

      Fix it by using 'sizeof(dimm->label) + 1' as the whole length in the
      snprintf()s in channel_dimm_label_show() and dimmdev_label_show().

      MODSIGN: Change from CMS to PKCS#7 signing if the openssl is too old

      The sign-file.c program actually uses CMS rather than PKCS#7 to sign a 
file
      since that allows the target X.509 certificate to be specified by
      subjectKeyId rather than by issuer + serialNumber.

      However, older versions of the OpenSSL crypto library (such as may be 
found
      in CentOS 5.11) don't support CMS.  Assume everything prior to
      OpenSSL-1.0.0 doesn't support CMS and switch to using PKCS#7 in that case.

      Further, the pre-1.0.0 OpenSSL only supports PKCS#7 signing with SHA1, so
      give an error from the sign-file script if the caller requests anything
      other than SHA1.

      The compiler gives the following error with an OpenSSL crypto library
      that's too old:

        HOSTCC  scripts/sign-file
      scripts/sign-file.c:23:25: fatal error: openssl/cms.h: No such file or 
directory

      X.509: Don't strip leading 00's from key ID when constructing key 
description

      Don't strip leading zeros from the crypto key ID when using it to 
construct
      the struct key description as the signature in kernels up to and including
      4.2 matched this aspect of the key.  This means that 1 in 256 keys won't
      actually match if their key ID begins with 00.

      The key ID is stored in the module signature as binary and so must be
      converted to text in order to invoke request_key() - but it isn't stripped
      at this point.

      Something like this is likely to be observed in dmesg when the key is 
loaded:

      [    1.572423] Loaded X.509 cert 'Build time autogenerated kernel
          key: 62a7c3d2da278be024da4af8652c071f3fea33'

      followed by this when we try and use it:

        [    1.646153] Request for unknown module key 'Build time autogenerated
          kernel key: 0062a7c3d2da278be024da4af8652c071f3fea33' err -11

      The 'Loaded' line should show an extra '00' on the front of the hex 
string.

      This problem should not affect 4.3-rc1 and onwards because there the key
      should be matched on one of its auxiliary identities rather than the key
      struct's description string.

      KEYS: Fix race between key destruction and finding a keyring by name

      There appears to be a race between:

       (1) key_gc_unused_keys() which frees key->security and then calls
           keyring_destroy() to unlink the name from the name list

       (2) find_keyring_by_name() which calls key_permission(), thus accessing
           key->security, on a key before checking to see whether the key usage 
is 0
           (ie. the key is dead and might be cleaned up).

      Fix this by calling ->destroy() before cleaning up the core key data -
      including key->security.

      IB/mlx5: Remove support for IB_DEVICE_LOCAL_DMA_LKEY

      Commit 96249d70dd70 ("IB/core: Guarantee that a local_dma_lkey
      is available") allows ULPs that make use of the local dma key to keep
      working as before by allocating a DMA MR with local permissions and
      converted these consumers to use the MR associated with the PD
      rather then device->local_dma_lkey.

      ConnectIB has some known issues with memory registration
      using the local_dma_lkey (SEND, RDMA, RECV seems to work ok).

      Thus don't expose support for it (remove device->local_dma_lkey
      setting), and take advantage of the above commit such that no regression
      is introduced to working systems.

      The local_dma_lkey support will be restored in CX4 depending on FW

      xprtrdma: Replace global lkey with lkey local to PD

      The core API has changed so that devices that do not have a global
      DMA lkey automatically create an mr, per-PD, and make that lkey
      available. The global DMA lkey interface is going away in favor of
      the per-PD DMA lkey.

      The per-PD DMA lkey is always available. Convert xprtrdma to use the
      device's per-PD DMA lkey for regbufs, no matter which memory
      registration scheme is in use.

      perf tools: Fix copying of /proc/kcore

      A copy of /proc/kcore containing the kernel text can be made to the
      buildid cache. e.g.

        perf buildid-cache -v -k /proc/kcore

      To workaround objdump limitations, a copy is also made when annotating
      against /proc/kcore.

      The copying process stops working from libelf about v1.62 onwards (the
      problem was found with v1.63).

      The cause is that a call to gelf_getphdr() in kcore__add_phdr() fails
      because additional validation has been added to gelf_getphdr().

      The use of gelf_getphdr() is a misguided attempt to get default
      initialization of the Gelf_Phdr structure.  That should not be
      necessary because every member of the Gelf_Phdr structure is
      subsequently assigned.  So just remove the call to gelf_getphdr().

      Similarly, a call to gelf_getehdr() in gelf_kcore__init() can be
      removed also.

      Committer notes:

      Note to stable@xxxxxxxxxx, from Adrian in the cover letter for this
      patchkit:

      The "Fix copying of /proc/kcore" problem goes back to v3.13 if you think
      it is important enough for stable.

      perf probe: Use existing routine to look for a kernel module by 
dso->short_name

      We have map_groups__find_by_name() to look at the list of modules that
      are in place for a given machine, so use it instead of traversing the
      machine dso list, which also includes DSOs for userspace.

      When merging the user and kernel DSO lists a bug was introduced where
      'perf probe' stopped being able to add probes to modules using its short
      name:

        # perf probe -m usbnet --add usbnet_start_xmit
        usbnet_start_xmit is out of .text, skip it.
          Error: Failed to add events.
        #

      With this fix it works again:

        # perf probe -m usbnet --add usbnet_start_xmit
        Added new event:
          probe:usbnet_start_xmit (on usbnet_start_xmit in usbnet)

        You can now use it in all perf tools, such as:

                perf record -e probe:usbnet_start_xmit -aR sleep 1

      KVM: x86: fix off-by-one in reserved bits check

      29ecd6601904 ("KVM: x86: avoid uninitialized variable warning",
      2015-09-06) introduced a not-so-subtle problem, which probably
      escaped review because it was not part of the patch context.

      Before the patch, leaf was always equal to iterator.level.  After,
      it is equal to iterator.level - 1 in the call to is_shadow_zero_bits_set,
      and when is_shadow_zero_bits_set does another "-1" the check on
      reserved bits becomes incorrect.  Using "iterator.level" in the call
      fixes this call trace:

      KVM: x86: use correct page table format to check nested page table 
reserved bits

      Intel CPUID on AMD host or vice versa is a weird case, but it can
      happen.  Handle it by checking the host CPU vendor instead of the
      guest's in reset_tdp_shadow_zero_bits_mask.  For speed, the
      check uses the fact that Intel EPT has an X (executable) bit while
      AMD NPT has NX.

      kvm_set_cr0 may want to call kvm_zap_gfn_range and thus access the

      is ugly, and adding it to kvm_arch_vcpu_create doesn't work because
      the VMX vcpu_create callback calls synchronize_srcu.

      x86/asm: Force inlining of cpu_relax()

      On x86, cpu_relax() simply calls rep_nop(), which generates one
      instruction, PAUSE (aka REP NOP).

      With this config:

        http://busybox.net/~vda/kernel_config_OPTIMIZE_INLINING_and_Os

      gcc-4.7.2 does not always inline rep_nop(): it generates several
      copies of this:

        <rep_nop> (16 copies, 194 calls):
             55                      push   %rbp
             48 89 e5                mov    %rsp,%rbp
             f3 90                   pause
             5d                      pop    %rbp
             c3                      retq

      See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66122

      This patch fixes this via s/inline/__always_inline/
      on rep_nop() and cpu_relax().

      ( Forcing inlining only on rep_nop() causes GCC to
        deinline cpu_relax(), with almost no change in generated code).

      x86/sched/64: Don't save flags on context switch (reinstated)

      This reinstates the following commit:

        2c7577a75837 ("sched/x86_64: Don't save flags on context switch")

      which was reverted in:

        512255a2ad2c ("Revert 'sched/x86_64: Don't save flags on context 
switch'")

      Historically, Linux has always saved and restored EFLAGS across
      context switches.  As far as I know, the only reason to do this
      is because of the NT flag.  In particular, if something calls
      switch_to() with the NT flag set, then we don't want to leak the
      NT flag into a different task that might try to IRET and fail
      because NT is set.

      Before this commit:

        8c7aa698baca ("x86_64, entry: Filter RFLAGS.NT on entry from userspace")

      we could run system call bodies with NT set.  This would be a DoS or 
possibly
      privilege escalation hole if scheduling in such a system call would leak
      NT into a different task.

      Importantly, we don't need to worry about NT being set while
      preemptible or across page faults.  The only way we can schedule
      due to preemption or a page fault is in an interrupt entry that
      nests inside the SYSENTER prologue.  The CPU will clear NT when
      entering through an interrupt gate, so we won't schedule with NT
      set.

      The only other interesting flags are IOPL and AC.  Allowing
      switch_to() to change IOPL has no effect, as the value loaded
      during kernel execution doesn't matter at all except between a
      SYSENTER entry and the subsequent PUSHF, and anythign that
      interrupts in that window will restore IOPL on return.

      If we call __switch_to() with AC set, we have bigger problems.

      iscsi-target: Avoid OFMarker + IFMarker negotiation

      This patch fixes a v4.2+ regression introduced by commit c04a6091
      that removed support for obsolete sync-and-steering markers usage
      as originally defined in RFC-3720.

      The regression would involve attempting to send OFMarker=No +
      IFMarker=No keys during opertional negotiation login phase,
      including when initiators did not actually propose these keys.

      The result for MSFT iSCSI initiators would be random junk in
      TCP stream after the last successful login request was been sent
      signaling the move to full feature phase (FFP) operation.

      To address this bug, go ahead and avoid negotiating these keys
      by default unless the initiator explicitly proposes them, but
      still respond to them with 'No' if they are proposed.

      target: Fix PR registration + APTPL RCU conversion regression

      This patch fixes a v4.2+ regression introduced by commit 79dc9c9e86
      where lookup of t10_pr_registration->pr_reg_deve and associated
      ->pr_kref get was missing from __core_scsi3_do_alloc_registration(),
      which is responsible for setting DEF_PR_REG_ACTIVE.

      This would result in REGISTER operations completing successfully,
      but subsequent core_scsi3_pr_seq_non_holder() checking would fail
      with !DEF_PR_REG_ACTIVE -> RESERVATION CONFLICT status.

      Update __core_scsi3_add_registration() to drop ->pr_kref reference
      after registration and any optional ALL_TG_PT=1 processing has
      completed.  Update core_scsi3_decode_spec_i_port() to release
      the new parent local_pr_reg->pr_kref as well.

      Also, update __core_scsi3_check_aptpl_registration() to perform
      the same target_nacl_find_deve() lookup + ->pr_kref get, now that
      __core_scsi3_add_registration() expects to drop the reference.

      Finally, since there are cases when se_dev_entry->se_lun_acl can
      still be dereferenced in core_scsi3_lunacl_undepend_item() while
      holding ->pr_kref, go ahead and move explicit rcu_assign_pointer()
      NULL assignments within core_disable_device_list_for_node() until
      after orig->pr_comp finishes.

      Phy, mdiobus, and netdev struct device fixes

      The third version of this series fixes the build error which David
      identified, and drops the broken changes for the Cavium Thunger BGX
      ethernet driver as this driver requires some complex changes to
      resolve the leakage - and this is best done by people who can test
      the driver.

      Compared to v2, the only patch which has changed is patch 6
        "net: fix phy refcounting in a bunch of drivers"

      I _think_ I've been able to build-test all the drivers touched by
      that patch to some degree now, though several of them needed the
      Kconfig hacked to allow it (not all had || COMPILE_TEST clause on
      their dependencies.)

      Previous cover letters below:

      This is the second version of the series, with the comments David had
      on the first patch fixed up.  Original series description with updated
      diffstat below.

      While looking at the DSA code, I noticed we have a
      of_find_net_device_by_node(), and it looks like users of that are
      similarly buggy - it looks like net/dsa/dsa.c is the only user.  Fix
      that too.

      Hi,

      While looking at the phy code, I identified a number of weaknesses
      where refcounting on device structures was being leaked, where
      modules could be removed while in-use, and where the fixed-phy could
      end up having unintended consequences caused by incorrect calls to
      fixed_phy_update_state().

      This patch series resolves those issues, some of which were discovered
      with testing on an Armada 388 board.  Not all patches are fully tested,
      particularly the one which touches several network drivers.

      When resolving the struct device refcounting problems, several different
      solutions were considered before settling on the implementation here -
      one of the considerations was to avoid touching many network drivers.
      The solution here is:

        phy_attach*() - takes a refcount
        phy_detach*() - drops the phy_attach refcount

      Provided drivers always attach and detach their phys, which they should
      already be doing, this should change nothing, even if they leak a 
refcount.

        of_phy_find_device() and of_* functions which use that take
        a refcount.  Arrange for this refcount to be dropped once
        the phy is attached.

      This is the reason why the previous change is important - we can't drop
      this refcount taken by of_phy_find_device() until something else holds
      a reference on the device.  This resolves the leaked refcount caused by
      using of_phy_connect() or of_phy_attach().

      Even without the above changes, these drivers are leaking by calling
      of_phy_find_device().  These drivers are addressed by adding the
      appropriate release of that refcount.

      The mdiobus code also suffered from the same kind of leak, but thankfully
      this only happened in one place - the mdio-mux code.

      I also found that the try_module_get() in the phy layer code was utterly
      useless: phydev->dev.driver was guaranteed to always be NULL, so
      try_module_get() was always being called with a NULL argument.  I proved
      this with my SFP code, which declares its own MDIO bus - the module use
      count was never incremented irrespective of how I set the MDIO bus up.
      This allowed the MDIO bus code to be removed from the kernel while there
      were still PHYs attached to it.

      One other bug was discovered: while using in-band-status with mvneta, it
      was found that if a real phy is attached with in-band-status enabled,
      and another ethernet interface is using the fixed-phy infrastructure, the
      interface using the fixed-phy infrastructure is configured according to
      the other interface using the in-band-status - which is caused by the
      fixed-phy code not verifying that the phy_device passed in is actually
      a fixed-phy device, rather than a real MDIO phy.

      Lastly, having mdio_bus reversing phy_device_register() internals seems
      like a layering violation - it's trivial to move that code to the phy
      device layer.

      net: fix net_device refcounting

      need to drop this refcount, and fix the DSA code to drop this refcount

      which undoes the effects of phy_device_register() by removing the phy
      device from visibility, but not freeing it.

      net: fix phy refcounting in a bunch of drivers

      of_phy_find_device() increments the phy struct device refcount, which
      we need to properly balance.  Add code to network drivers using this
      function to ensure that the struct device refcount is correctly
      balanced.

      For xgene, looking back in the history, we should be able to use
      of_phy_connect() with a zero flags argument for the DT case as this is
      how the driver used to operate prior to de7b5b3d790a ("net: eth: xgene:
      change APM X-Gene SoC platform ethernet to support ACPI").

      This leaves the Cavium Thunder BGX unfixed; fixing this driver is a
      complicated task, one which the maintainers need to be involved with.

      of_mdio: fix MDIO phy device refcounting

      bus_find_device() is defined as:

       * This is similar to the bus_for_each_dev() function above, but it
       * returns a reference to a device that is 'found' for later use, as
       * determined by the @match callback.

      and it does indeed return a reference-counted pointer to the device:

              while ((dev = next_device(&i)))
                      if (match(dev, data) && get_device(dev))
                                              ^^^^^^^^^^^^^^^
                              break;
              klist_iter_exit(&i);
              return dev;

      What that means is that when we're done with the struct device, we must
      drop that reference.  Neither of_phy_connect() nor of_phy_attach() did
      this when phy_connect_direct() or phy_attach_direct() failed.

      With our previous patch, phy_connect_direct() and phy_attach_direct()
      take a new refcount on the phy device when successful, so we can drop
      our local reference immediatley after these functions, whether or not
      they succeeded.

      phy: add proper phy struct device refcounting

      Take a refcount on the phy struct device when the phy device is attached
      to a network device, and drop it after it's detached.  This ensures that
      a refcount is held on the phy device while the device is being used by
      a network device, thereby preventing the phy_device from being
      unexpectedly kfree()'d by phy_device_release().

      phy: fix mdiobus module safety

      Re-implement the mdiobus module refcounting to ensure that we actually
      ensure that the mdiobus module code does not go away while we might call
      into it.

      The old scheme using bus->dev.driver was buggy, because bus->dev is a
      class device which never has a struct device_driver associated with it,
      and hence the associated code trying to obtain a refcount did nothing
      useful.

      Instead, take the approach that other subsystems do: pass the module
      when calling mdiobus_register(), and record that in the mii_bus struct.
      When we need to increment the module use count in the phy code, use
      this stored pointer.  When the phy is deteched, drop the module
      refcount, remembering that the phy device might go away at that point.

      This doesn't stop the mii_bus going away while there are in-use phys -
      it merely stops the underlying code vanishing.

      net: dsa: fix of_mdio_find_bus() device refcount leak

      Current users of of_mdio_find_bus() leak a struct device refcount, as
      they fail to clean up the reference obtained inside class_find_device().

      Fix the DSA code to properly refcount the returned MDIO bus by:
      1. taking a reference on the struct device whenever we assign it to
         pd->chip[x].host_dev.
      2. dropping the reference when we overwrite the existing reference.
      3. dropping the reference when we free the data structure.
      4. dropping the initial reference we obtained after setting up the
         platform data structure, or on failure.

      In step 2 above, where we obtain a new MDIO bus, there is no need to
      take a reference on it as we would only have to drop it immediately
      after assignment again, iow:

        put_device(cd->host_dev);       /* drop original assignment ref */
        cd->host_dev = get_device(&mdio_bus_switch->dev); /* get our ref */
        put_device(&mdio_bus_switch->dev); /* drop of_mdio_find_bus ref */

      dmaengine: idma64: improve residue estimation

      The residue calculation may provide a wrong estimation when the transfer 
is
      started. There are possible scenarios we have to separate:

        1) the transfer is not started yet; residue is equal to the total
           length;

        2) the transfer is just started (first chunk is ongoing); residue is
           equal to the total length without already transfered bytes;

        3) the transfer is ongoing and we already sent few chunks of data;
           residue is equal to the total length without fully transfered chunks
           and already sent bytes.

      Mistakenly the calculation in cases 2) and 3) was done in the similar way 
and
      the result is equal to -bytes that have been transfered, i.e. quite big 
since
      size_t type can't keep negative values.

      Rewrite the calculation algorithm to be one pass and have a correct 
result.

      Besides above in case user asks for a status of the active DMA descriptor
      without pausing an ongoing transfer the residue will be estimated based 
on the
      register value, though it's still racy. Since the transfer is active the 
value
      is continuously being changed. Here we have to read two registers at a 
time. To
      minimize an error make those reads close to each other.

      ====================
      Second Round of IPVS Updates for v4.4

      please consider these bug fixes and extensive clean-ups of IPVS
      from Eric Biederman for v4.4.

      His excellent description of the changes, which is part of an even larger
      set of clean-up work, is as follows:

        I am gradually working my way through the netfilter stack passing struct
        down into the netfilter hooks and from the netfilter hooks and from 
there
        down into the functions that actually care.  This removes the need for
        netfilter functions to guess how to figure out how to compute which
        network namespace they are in and instead provides a simple and reliable
        method to do so.

        The cleanups stand on their own but this is part of a larger effort to
        have routes with an output device that is not in the current network
        namespace.

        The IPVS code has been a bit more of a challenge than most.  Just 
passing
        struct net through to where it is needed did not feel clean to me.  The
        practical issue is that the ipvs code in most places actually wants
        struct netns_ipvs and not struct net.

        So as part of this process I have turned the relationship between struct
        net and the structs netns_ipvs, ip_vs_conn_param, ip_vs_conn, and
        ip_vs_service inside out.  I have modified the ipvs functions to take a
        struct netns_ipvs not a struct net.  The net is code with fewer
        conversions from one type of structure to another.  I did wind up adding
        a struct netns_ipvs parameter to quite a few functions that did not have
        it before so I could pass the structure down from the netfilter hooks to
        where it is actually needed to avoid guessing.

        I have broken up the work in a bunch of small patches so there is at
        least a chance and reviewing that each step I took is correct.  The
        series compiles at each step so bisecting it should not be a problem if
        something weird comes up.

        The first two changes in this series are actually bug fixes.  The first
        is a compile fix for a bug in sctp that came in, in the last round of
        ipvs changes merged into nf-next.  The second fixes an older bug where 
in
        pathological circumstances the wrong network namespace could be used 
when
        a proc file is written to.

        The rest of the patchset is a bunch of boring changes getting pushing
        struct netns_ipvs (and by extension ipvs->net) where it needs to be.
        Either by replacing struct net pointers or adding new struct netns_ipvs
        pointers.  With a handful of other minor cleanups (like removing
        skb_net).

      I have decided include the bug fixes in this pull request. Patch one
      relates to a bug that was added to nf-next recently and is thus not
      applicable to nf . Patch two could arguably be promoted to a fix for v4.3
      and stable though it does not appear to be severe enough to warrant that
      course of action; let me know if you would like me to reconsider.

      ARM: dts: fix omap2+ address translation for pbias

      "ARM: dts: <omap2/omap4/omap5/dra7>: add minimal l4 bus
      layout with control module support" moved pbias_regulator dt node
      from being a child node of ocp to be the child node of
      'syscon'. Since 'syscon' doesn't have the 'ranges' property,
      address translation fails while trying to convert the address
      to resource. Fix it here by populating 'ranges' property in

      ip6_tunnel: Reduce log level in ip6_tnl_err() to debug

      Currently error log messages in ip6_tnl_err are printed at 'warn'
      level. This is different to other tunnel types which don't print
      any messages. These log messages don't provide any information that
      couldn't be deduced with networking tools. Also it can be annoying
      to have one end of the tunnel go down and have the logs fill with
      pointless messages such as "Path to destination invalid or inactive!".

      This patch reduces the log level of these messages to 'dbg' level to
      bring the visible behaviour into line with other tunnel types.

      Documentation: arm: Fix typo in the idle-states bindings examples

      The idle-states bindings mandate that the entry-method string
      in the idle-states node must be "psci" for ARM v8 64-bit systems,
      but the examples in the bindings report a wrong entry-method string.
      Owing to this typo, some dts in the kernel wrongly defined the
      entry-method property, since they likely cut and pasted the example
      definition without paying attention to the bindings definitions.

      This patch fixes the typo in the DT idle states bindings examples and
      respective dts in the kernel so that the bindings and related dts
      files are made compliant.

      gpio: mention in DT binding doc that <name>-gpio is deprecated

      The gpiolib supports parsing DT properties of the form <name>-gpio but it
      was only added for compatibility with older DT bindings that got it wrong
      and should not be used in newer bindings.

      The commit that added support for this was:

      dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property names")

      but didn't update the documentation to explain this so it's been a source
      of confusion. So let's make this clear in the GPIO DT binding doc.

      Intel Wired LAN Driver Updates 2015-09-23

      This series contains updates to ixgbe only.

      Mark provides all the changes in this series, first clears the destination
      location for I2C data initially so that the received data will not be
      corrupted by previous attempts.  Then reduced the pauses/delays in the
      PHY detection when no SFP is present by reducing the number of retires,
      once an SFP is detected, the "normal" number of retries in PHY detection
      will be used.  Added support for X55EM_x SFP+ dual-speed, and fixed 1G and
      10G link stability for X550EM_x by configuring the CS4227 correctly by
      moving code to ixgbe_setup_mac_link_sfp_x550em().  Added functionality to
      reset CS4227, since on some platforms the CS4227 does not initialize
      properly.  Next reduces the SFP polling rate, due to when an SFP is not
      present, the I2C timeouts that result are very costly.  So prevent the
      SFP polling from being done more than once every two seconds.  Added
      support for I2C bus MUX.  Fixed the setting of RDRXCTL register which
      should fall through X540 and 82599, not 82598.  In addition, added small
      packet padding support in X550 by setting RDRXCTL.PSP when the driver is
      in SRIOV mode.  Fixed a known hardware issue where the PCI transactions
      pending bit sticks high when there are pending transactions, so
      workaround the issue by wait and then continue with our reset flow.
      Added a new device ID for X550EM device with SFPs.  Provided a fix with
      the DCA setup, which was suggested by Alex Duyck <aduyck@xxxxxxxxxxxx>,
      by making it so that we always set the relaxed ordering bits related to
      the DCA registers even if DCA is not enbaled.  Then moves the
      configuration out of the ixgbe_down() and into ixgbe_configure() before
      enabling the transmit and receive rings.  This ensures that DCA is
      configured correctly before starting the processing of packets.
      Fixed VM-to-VM loopback mode which requires that FCRTH be set, but
      the datasheets did not specify what the value should be.  It has now
      been determined that the correct value should be RXPBSIZE - (24*1024).

      fib_rules: fix fib rule dumps across multiple skbs

      dump_rules returns skb length and not error.
      But when family == AF_UNSPEC, the caller of dump_rules
      assumes that it returns an error. Hence, when family == AF_UNSPEC,
      we continue trying to dump on -EMSGSIZE errors resulting in
      incorrect dump idx carried between skbs belonging to the same dump.
      This results in fib rule dump always only dumping rules that fit
      into the first skb.

      This patch fixes dump_rules to return error so that we exit correctly
      and idx is correctly maintained between skbs that are part of the
      same dump.

      PCI: Use function 0 VPD for identical functions, regular VPD for others

      932c435caba8 ("PCI: Add dev_flags bit to access VPD through function 0")
      added PCI_DEV_FLAGS_VPD_REF_F0.  Previously, we set the flag on every
      non-zero function of quirked devices.  If a function turned out to be
      different from function 0, i.e., it had a different class, vendor ID, or
      device ID, the flag remained set but we didn't make VPD accessible at all.

      Flip this around so we only set PCI_DEV_FLAGS_VPD_REF_F0 for functions 
that
      are identical to function 0, and allow regular VPD access for any other
      functions.

      Commit 932c435caba8 ("PCI: Add dev_flags bit to access VPD through

      Generally this works because we're fairly well guaranteed that a PCIe
      device is at slot address 0, but for the general case, including
      conventional PCI, it's incorrect.  We need to get the slot and then 
convert
      it back into a devfn.

      PCI/MSI: Fix MSI IRQ domains for VFs on virtual buses

      SR-IOV creates a virtual bus where bus->self is NULL.  When we add VFs and
      scan for an MSI domain, pci_set_bus_msi_domain() dereferences bus->self,
      which causes a kernel NULL pointer dereference oops.

      bnx2x: byte swap rss_key to comply to Toeplitz specs

      After a good amount of debugging, I found bnx2x was byte swaping
      the 40 bytes of rss_key.

      If we byte swap the key, then bnx2x generates hashes matching
      MSDN specs as documented in (Verifying the RSS Hash Calculation)

      https://msdn.microsoft.com/en-us/library/windows/hardware/ff571021%
      28v=vs.85%29.aspx

      It is mostly a non issue, unless we want to mix different NIC
      in a host, and want consistent hashing among all of them, ie
      if they all use the boot time generated rss key, or if some application
      is choosing specific tuple(s) so that incoming traffic lands into known
      rx queue(s).

      ====================
      lwtunnel: make it really work, for IPv4

      One of the selling points of lwtunnel was the ability to specify the 
tunnel
      destination using routes. However, this doesn't really work currently, as
      ARP and ndisc replies are not handled correctly. ARP and ndisc replies 
won't
      have tunnel metadata attached, thus they will be sent out with the default
      parameters or not sent at all, either way never reaching the requester.

      Most of the egress tunnel parameters can be inferred from the ingress
      metada. The only and important exception is UDP ports. This patchset 
infers
      the egress data from the ingress data and disallow settings of UDP ports 
in
      tunnel routes. If there's a need for different UDP ports, a new interface
      needs to be created for each port combination. Note that it's still 
possible
      to specify the UDP ports to use, it just needs to be done while creating 
the
      vxlan/geneve interface.

      This covers only ARPs. IPv6 ndisc has the same problem but is harder to
      solve, as there's already dst attached to outgoing skbs. Ideas to solve 
this
      are welcome.

      lwtunnel: remove source and destination UDP port config option

      The UDP tunnel config is asymmetric wrt. to the ports used. The source and
      destination ports from one direction of the tunnel are not related to the
      ports of the other direction. We need to be able to respond to ARP 
requests
      using the correct ports without involving routing.

      As the consequence, UDP ports need to be fixed property of the tunnel
      interface and cannot be set per route. Remove the ability to set ports per
      route. This is still okay to do, as no kernel has been released with these
      attributes yet.

      Note that the ability to specify source and destination ports is preserved
      for other users of the lwtunnel API which don't use routes for tunnel key
      specification (like openvswitch).

      If in the future we rework ARP handling to allow port specification, the
      attributes can be added back.

      ipv4: send arp replies to the correct tunnel

      When using ip lwtunnels, the additional data for xmit (basically, the 
actual
      tunnel to use) are carried in ip_tunnel_info either in dst->lwtstate or in
      metadata dst. When replying to ARP requests, we need to send the reply to
      the same tunnel the request came from. This means we need to construct
      proper metadata dst for ARP replies.

      We could perform another route lookup to get a dst entry with the correct
      lwtstate. However, this won't always ensure that the outgoing tunnel is 
the
      same as the incoming one, and it won't work anyway for IPv4 duplicate
      address detection.

      The only thing to do is to "reverse" the ip_tunnel_info.

      skbuff: Fix skb checksum flag on skb pull

      VXLAN device can receive skb with checksum partial. But the checksum
      offset could be in outer header which is pulled on receive. This results
      in negative checksum offset for the skb. Such skb can cause the assert
      failure in skb_checksum_help(). Following patch fixes the bug by setting
      checksum-none while pulling outer header.

      cgroup, writeback: don't enable cgroup writeback on traditional 
hierarchies

      inode_cgwb_enabled() gates cgroup writeback support.  If it returns
      true, each inode is attached to the corresponding memory domain which
      gets mapped to io domain.  It currently only tests whether the
      filesystem and bdi support cgroup writeback; however, cgroup writeback
      support doesn't work on traditional hierarchies and thus it should
      also test whether memcg and iocg are on the default hierarchy.

      This caused traditional hierarchy setups to hit the cgroup writeback
      path inadvertently and ended up creating separate writeback domains
      for each memcg and mapping them all to the root iocg uncovering a
      couple issues in the cgroup writeback path.

      cgroup writeback was never meant to be enabled on traditional
      hierarchies.  Make inode_cgwb_enabled() test whether both memcg and
      iocg are on the default hierarchy.

      OK I've decided to drop the acquire/release helpers as they don't
      help us at all and simply pessimises the code by using full memory
      barriers (on some architectures) where only a write or read barrier
      is needed.

      But you are right we do need an explicit write barrier here to
      ensure that the hashing is visible.

      It's not about being overly smart.  It's about actually understanding
      what's going on with the code.  I've seen too many instances of
      people simply sprinkling synchronisation primitives around without
      any knowledge of what is happening underneath, which is just a recipe
      for creating hard-to-debug races.

      The reason this one is OK is because we do not use nlk->portid or
      try to get nlk from the hash table before we return to user-space.

      However, there is a real bug here that none of these acquire/release
      helpers discovered.  The two bound tests here used to be a single
      one.  Now that they are separate it is entirely possible for another
      thread to come in the middle and bind the socket.  So we need to
      repeat the portid check in order to maintain consistency.

      The commit 1f770c0a09da855a2b51af6d19de97fb955eca85 ("netlink:
      Fix autobind race condition that leads to zero port ID") created
      some new races that can occur due to inconcsistencies between the
      two port IDs.

      Tejun is right that a barrier is unavoidable.  Therefore I am
      reverting to the original patch that used a boolean to indicate
      that a user netlink socket has been bound.

      Barriers have been added where necessary to ensure that a valid
      portid and the hashed socket is visible.

      I have also changed netlink_insert to only return EBUSY if the
      socket is bound to a portid different to the requested one.  This
      combined with only reading nlk->bound once in netlink_bind fixes
      a race where two threads that bind the socket at the same time
      with different port IDs may both succeed.

      ALSA: hda - Disable power_save_node for Thinkpads

      Lenovo Thinkpads with recent Realtek codecs seem suffering from click
      noises at power transition since the introduction of widget power
      saving in 4.1 kernel.  Although this might be solved by some delays in
      appropriate points, as a quick workaround, just disable the
      power_save_node feature for now.  The gain it gives is relatively
      small, and this makes the situation back to pre 4.1 time.

      This patch ended up with a bit more code changes than usual because
      the existing fixup for Thinkpads is highly chained.  Instead of adding
      yet another chain, combine a few of them into a single fixup entry, as
      a gratis cleanup.

      The callback "create" and "parse" from header_ops are called from

      assumes big endian for addresses and we should not introduce a special

      We have an identical issue with setting the mac address which also

      EDAC, sb_edac: Fix TAD presence check for sbridge_mci_bind_devs()

      In commit

        7d375bffa524 ("sb_edac: Fix support for systems with two home agents 
per socket")

      NUM_CHANNELS was changed to 8 and the channel space was renumerated to
      handle EN, EP, and EX configurations.

      The *_mci_bind_devs() functions - except for sbridge_mci_bind_devs() -
      got a new device presence check in the form of saw_chan_mask. However,
      sbridge_mci_bind_devs() still uses the NUM_CHANNELS for loop.

      With the increase in NUM_CHANNELS, this loop fails at index 4 since
      SB only has 4 TADs.  This results in the following error on SB machines:

        EDAC sbridge: Some needed devices are missing
        EDAC sbridge: Couldn't find mci handler
        EDAC sbridge: Couldn't find mci handle

      This patch adapts the saw_chan_mask logic for sbridge_mci_bind_devs() as
      well.

      gpio: keep the GPIO line names internal

      This refactors the changes to the GPIO line naming mechanism to
      not have so widespread effects, instead we conclude the patch series
      by having created a name attribute in the GPIO descriptor, that need
      not be globally unique, and it will be initialized from the old
      .names array in struct gpio_chip if it exists, then used in the legacy
      sysfs code like the array was used previously.

      The associated changes to name lines from the device tree are
      controversial and need to stand alone from this. Resulting changes:

      1. Remove the export and the header for the gpio_name_to_desc() as so
      far the only use is inside gpiolib.c. Staticize gpio_name_to_desc()
      and move it above the only function using it.

      2. Only print a warning if there are two GPIO lines with the same name.
      The reason is to preserve current behaviour: before the previous
      changes to the naming mechanism this would not reject probing the
      driver, instead the error would occur when trying to export the line
      in sysfs, so restore this behaviour, but print a friendly warning
      if names collide.

      gpio: Introduce gpio descriptor 'name'

      The latest gpio hogging mechanism assigns each gpio a 'line-name' in the
      devicetree. The 'name' field is different from the 'label' field.
      'label' is only used for requested GPIOs to describe its current use by
      driver or userspace.

      The 'name' field describes the GPIO itself, not the use. This is most
      likely identical to the label in the schematic on the GPIO line and
      should help to find this particular GPIO.

      This is equivalent to the gpiochip->names array. However names should be
      stored in the GPIO descriptor. We will use gpiochip->names in the future
      only as initializer for the GPIO descriptors for drivers that assign
      GPIO names hardcoded. All other GPIO names will be parsed from DT and
      directly assigned to the GPIO descriptor.

      This patch adds a helper function to find gpio descriptors by name
      instead of gpio number.

      Bluetooth: Remove useless rx_lock spinlock

      rx_lock spinlock is only used in hci_uart_tty_receive() which is the
      receive_buf ldisc callback.

      hci_uart_tty_receive() is protected from re-entrance by its only
      caller (flush_to_ldisc() in drivers/tty/tty_buffer.c) which held a
      mutex (buf->lock) for this section.
      This lock allows "safe use of the line discipline's receive_buf()
      method by excluding the buffer work and any pending flush from using
      the flip buffer." (comments from tty_buffer_lock_exclusive() in
      drivers/tty/tty_buffer.c)

      So, no need to double protect this resource with rx_lock.

      ALSA: hda/tegra - async probe for avoiding module loading deadlock

      The Tegra HD-audio controller driver causes deadlocks when loaded as a
      module since the driver invokes request_module() at binding with the
      codec driver.  This patch works around it by deferring the probe in a
      work like Intel HD-audio controller driver does.  Although hovering
      the codec probe stuff into udev would be a better solution, it may
      cause other regressions, so let's try this band-aid fix until the more
      proper solution gets landed.

      When the kernel is compiled with -Os (CONFIG_CC_OPTIMIZE_FOR_SIZE), 
tridentfb
      hangs the machine upon load with Blade3D cards unless acceleration is 
disabled.

      This is caused by memcpy() which copies data byte-by-byte (rep movsb) when
      compiled with -Os. The card does not like that - it requires 32-bit 
access.

      Use iowrite_32() instead.

      drm: Allow also control clients to check the drm version

      This should be harmless.
      Vmware will, due to old infrastructure reasons, be using a privileged
      control client to supply GUI layout information rather than obtaining
      it from the device. That control client will be needing access to DRM
      version information.

      ixgbe: Correct several flaws with with DCA setup

      This change does two things. First, it makes it so that we always
      set the relaxed ordering bits related to the DCA registers even if
      DCA is not enabled. Second, it moves the configuration out of the
      ixgbe_down function and into the ixgbe_configure function before
      enabling the Rx and Tx rings. This ensures that DCA is configured
      correctly before starting to process packets.

      ixgbe: Limit SFP polling rate

      Reduce the frequency of polling for SFP modules. Because the

      SFPs too often. When an SFP is not present, the I2C timeouts
      that result are very costly. So, prevent SFP polling from
      being done more than once every two seconds. To reduce latency,
      the poll time is cleared in a couple of cases to permit the
      next service task execution to poll the SFP module.

      ixgbe: Fix 1G and 10G link stability for X550EM_x SFP+

      Configures the CS4227 correctly for both 1G and 10G operation,
      by moving the code to ixgbe_setup_mac_link_sfp_x550em(). It
      needs to be in this function because we need both the module
      type and the speed, and this is the only function in the init
      flow that knows the speed. In contrast,
      ixgbe_setup_sfp_modules_X550em() does not know the speed, so we
      can't do anything useful here. This is a fundamental difference
      from the previous flow, and is due to the way the CS4227 is
      implemented.

      ixgbe: Add X550EM_x dual-speed SFP+ support

      This patch adds X550EM_x SFP+ dual-speed support. 82599 fiber link
      code was moved from ixgbe_82599.c to ixgbe_common.c for use by
      X550EM. SFP MAC link code is added to x550EM.

      ipvs: Store ipvs not net in struct ip_vs_sync_thread_data

      In practice struct netns_ipvs is as meaningful as struct net and more
      useful as it holds the ipvs specific data.  So store a pointer to
      struct netns_ipvs.

      Update the accesses of tinfo->net to access tinfo->ipvs->net instead.

      ipvs: Pass ipvs not net to ip_vs_svc_hashkey

      Use the address of ipvs not the address of net when computing the
      hash value.  This removes an unncessary dependency on struct net.

      drm/mgag200: Fix driver_load error handling

      mgag200_driver_load's error path just calls the drm driver's
      driver_unload op. It isn't safe to call this because it doesn't handle
      things well if driver_load fails somewhere mid way.

      Replace the call to mgag200_driver_unload with a more finegrained
      error handling path.

      Intel Wired LAN Driver Updates 2015-09-22

      This series contains updates to e1000, e1000e, igbvf, ixgbe, ixgbevf and
      fm10k.

      Jacob provides several updates for fm10k, which cleans up comments and
      most notably a fix for a corner case issue with the PF/VF mailbox code.
      The issue being fm10k_mbx_reset_work clears various states about the
      mailbox, but does not clear the Tx FIFO head/tail pointers.  We also
      are not able to simply clear these pointers, as we would drop
      untransmitted messages without error.  Also adds support for extra debug
      statistics, which provides the ability to see what the PF thinks the
      VF mailboxes look like.

      Don adds support for SFP+ in X550 and support for SCTP flow director
      filters SCTP mask.

      Francois Romieu dusts off the e1000 driver and removes some dead calls
      to e1000_init_eeprom_params().

      Toshiaki Makita provides three patches to enable TSO for stacked VLAN's
      on e1000e, igbvf and ixgbevf.

      Mark provides the first of several ixgbe updates.  First updates the
      driver to accept SFP not present error for all devices, since an SFP
      can still be inserted.  Adds support for SFP insertion interrupt on
      X550EM devices with SPFs.  Adds I2C combined operations on X550EM
      (not X550) devices.  Moved the setting of lan_id to before any I2C
      eeprom access.  Lastly, set the bit bang mode in the hardware when
      performing bit banding I2C operations on X550.

      8139cp: Fix DMA unmapping of transmitted buffers

      The low 16 bits of the 'opts1' field in the TX descriptor are supposed
      to still contain the buffer length when the descriptor is handed back to
      us. In practice, at least on my hardware, they don't. So stash the
      original value of the opts1 field and get the length to unmap from
      there.

      There are other ways we could have worked out the length, but I actually
      want a stash of the opts1 field anyway so that I can dump it alongside
      the contents of the descriptor ring when we suffer a TX timeout.

      8139cp: Do not re-enable RX interrupts in cp_tx_timeout()

      If an RX interrupt was already received but NAPI has not yet run when
      the RX timeout happens, we end up in cp_tx_timeout() with RX interrupts
      already disabled. Blindly re-enabling them will cause an IRQ storm.

      (This is made particularly horrid by the fact that cp_interrupt() always
      returns that it's handled the interrupt, even when it hasn't actually
      done anything. If it didn't do that, the core IRQ code would have
      detected the storm and handled it, I'd have had a clear smoking gun
      backtrace instead of just a spontaneously resetting router, and I'd have
      at *least* two days of my life back. Changing the return value of
      cp_interrupt() will be argued about under separate cover.)

      Unconditionally leave RX interrupts disabled after the reset, and
      schedule NAPI to check the receive ring and re-enable them.

      The trace log is provided below for reference. This patch fixes the
      bug by removing the usage of netcp_modules_lock within ndo_ops functions.
      ndo_{open/close/ioctl)() is already called with rtnl_lock held. So there
      is no need to hold another mutex for serialization across processes on
      multiple cores.  So remove use of netcp_modules_lock mutex from these
      ndo ops functions.

      ndo_set_rx_mode() shouldn't be using a mutex as it is called from atomic
      context. In the case of ndo_set_rx_mode(), there can be call to this API
      without rtnl_lock held from an atomic context. As the underlying modules
      are expected to add address to a hardware table, it is to be protected
      across concurrent updates and hence a spin lock is used to synchronize
      the access. Same with ndo_vlan_rx_add_vid() & ndo_vlan_rx_kill_vid().

      Probably the netcp_modules_lock is used to protect the module not being
      removed as part of rmmod. Currently this is not fully implemented and
      assumes the interface is brought down before doing rmmod of modules.
      The support for rmmmod while interface is up is expected in a future
      patch set when additional modules such as pa, qos are added. For now
      all of the tests such as if up/down, reboot, iperf works fine with this
      patch applied.

      Deadlock trace seen with lockup detector enabled is shown below for
      reference.

      net: netcp: allocate buffers to desc before re-enable interrupt

      Currently netcp_rxpool_refill() that refill descriptors and attached
      buffers to fdq while interrupt is enabled as part of NAPI poll. Doing
      it while interrupt is disabled could be beneficial as hardware will
      not be starved when CPU is busy with processing interrupt.

      net: netcp: move netcp_register_interface() to after attach module

      The netcp interface is not fully initialized before attach the module
      to the interface. For example, the tx pipe/rx pipe is initialized
      in ethss module as part of attach(). So until this is complete, the

      net: netcp: ethss: fix error in calling sgmii api with incorrect offset

      On K2HK, sgmii module registers of slave 0 and 1 are mem
      mapped to one contiguous block, while those of slave 2
      and 3 are mapped to another contiguous block.  However,
      on K2E and K2L, sgmii module registers of all slaves are
      mem mapped to one contiguous block.  SGMII APIs expect
      slave 0 sgmii base when API is invoked for slave 0 and 1,
      and slave 2 sgmii base when invoked for other slaves.
      Before this patch, slave 0 sgmii base is always passed to
      sgmii API for K2E regardless which slave is the API invoked
      for.  This patch fixes the problem.

      ====================
      bridge: don't age out externally added FDB entries

      v3: Per davem review: add del_timer_sync on rocker port remove.

      v2: Per Jiri review comment: add BR_DEFAULT_AGEING_TIME to defines

      Siva originally proposed skipping externally added FDB entries in the 
bridge's
      FDB garbage collection func, and moving the ageing of externally added 
entries
      to the port driver/device.  This broke rocker, since rocker didn't have a
      hardware (or software) mechanism for ageing out its learned FDB entries.

      This patchset reintroduces Siva's bridge driver patch to skip externally 
added
      entries and adds support in rocker so rocker can age out its own entries.
      Rocker does this using a software timer similar to the bridge's FDB 
garbage
      collection timer.  Other switchdev devices/drivers can use this software 
timer
      method or program the device to nofity aged-out entries to the driver.

      Updated switchdev.txt documentation to reflect current state-of-the-art.  
This
      removes one more XXX todo comment in switchdev.txt.

      Since virtio_legacy_is_little_endian() is a very long identifier,
      define a vio_le macro and use that throughout the code instead of the
      hard-coded 'false' for little-endian.

      netpoll: Close race condition between poll_one_napi and napi_disable

      Drivers might call napi_disable while not holding the napi instance 
poll_lock.
      In those instances, its possible for a race condition to exist between
      poll_one_napi and napi_disable.  That is to say, poll_one_napi only tests 
the
      NAPI_STATE_SCHED bit to see if there is work to do during a poll, and as 
such
      the following may happen:

      CPU0                              CPU1
      ndo_tx_timeout                    napi_poll_dev
       napi_disable                      poll_one_napi
        test_and_set_bit (ret 0)
                                  test_bit (ret 1)
         reset adapter             napi_poll_routine

      If the adapter gets a tx timeout without a napi instance scheduled, its 
possible
      for the adapter to think it has exclusive access to the hardware  (as the 
napi
      instance is now scheduled via the napi_disable call), while the netpoll 
code
      thinks there is simply work to do.  The result is parallel hardware access
      leading to corrupt data structures in the driver, and a crash.

      Additionaly, there is another, more critical race between netpoll and
      napi_disable.  The disabled napi state is actually identical to the 
scheduled
      state for a given napi instance.  The implication being that, if a napi 
instance
      is disabled, a netconsole instance would see the napi state of the device 
as
      having been scheduled, and poll it, likely while the driver was dong 
something
      requiring exclusive access.  In the case above, its fairly clear that not 
having
      the rings in a state ready to be polled will cause any number of crashes.

      The fix should be pretty easy.  netpoll uses its own bit to indicate that 
that
      the napi instance is in a state of being serviced by netpoll 
(NAPI_STATE_NPSVC).
      We can just gate disabling on that bit as well as the sched bit.  That 
should
      prevent netpoll from conducting a napi poll if we convert its set bit to a
      test_and_set_bit operation to provide mutual exclusion

      V2)

      cls_bpf: further limit exec opcodes subset

      Jamal suggested to further limit the currently allowed subset of opcodes
      that may be used by a direct action return code as the intention is not
      to replace the full action engine, but rather to have a minimal set that
      can be used in the fast-path on things like ingress for some features
      that cls_bpf supports.

      Classifiers can, of course, still be chained together that have direct
      action mode with those that have a full exec pass. For more complex
      scenarios that go beyond this minimal set here, the full tcf_exts_exec()
      path must be used.

      cls_bpf: make binding to classid optional

      The binding to a particular classid was so far always mandatory for

      as similarly done in other classifiers.

      Only a couple of qdiscs make use of class from the tcf_result, others
      don't strictly care, so let the user choose his needs (those that read
      out class can handle situations where it could be NULL).

      An explicit check for tcf_unbind_filter() is also not needed here, as
      the previous r->class was 0, so the xchg() will return that and
      therefore a callback to the qdisc's unbind_tcf() is skipped.

      tcp: add proper TS val into RST packets

      RST packets sent on behalf of TCP connections with TS option (RFC 7323
      TCP timestamps) have incorrect TS val (set to 0), but correct TS ecr.

      A > B: Flags [S], seq 0, win 65535, options [mss 1000,nop,nop,TS val 100
      ecr 0], length 0
      B > A: Flags [S.], seq 2444755794, ack 1, win 28960, options [mss
      1460,nop,nop,TS val 7264344 ecr 100], length 0
      A > B: Flags [.], ack 1, win 65535, options [nop,nop,TS val 110 ecr
      7264344], length 0

      B > A: Flags [R.], seq 1, ack 1, win 28960, options [nop,nop,TS val 0
      ecr 110], length 0

      We need to call skb_mstamp_get() to get proper TS val,
      derived from skb->skb_mstamp

      Note that RFC 1323 was advocating to not send TS option in RST segment,
      but RFC 7323 recommends the opposite :

        Once TSopt has been successfully negotiated, that is both <SYN> and
        <SYN,ACK> contain TSopt, the TSopt MUST be sent in every non-<RST>
        segment for the duration of the connection, and SHOULD be sent in an
        <RST> segment (see Section 5.2 for details)

      Note this RFC recommends to send TS val = 0, but we believe it is
      premature : We do not know if all TCP stacks are properly
      handling the receive side :

         When an <RST> segment is
         received, it MUST NOT be subjected to the PAWS check by verifying an
         acceptable value in SEG.TSval, and information from the Timestamps
         option MUST NOT be used to update connection state information.
         SEG.TSecr MAY be used to provide stricter <RST> acceptance checks.

      In 5 years, if/when all TCP stack are RFC 7323 ready, we might consider
      to decide to send TS val = 0, if it buys something.

          drm: Check locking in drm_for_each_connector

      I added locking checks to drm_for_each_connector but failed that
      through drm_helper_connector_dpms -> drm_helper_choose_encoder_dpms
      it's used in a few more places in the amdgpu resume/suspend code.

      Fix them up.

      Note that we could use the connector iterator macros in there too, but
      that's for the future.

      drm/amdgpu: sync ce and me with SWITCH_BUFFER(2)

      we used to adopt wait_reg_mem to let CE wait before DE finish page
      updating, but from Tonga+, CE doesn't support wait_reg_mem package so
      this logic no longer works.

      so here is another approach to do same thing:
      Insert two of SWITCH_BUFFER at both front and end of vm_flush can
      guarantee that CE not go further to process IB_const before vm_flush
      done.

      Insert two of SWITCH_BUFFER also works on CI, so remove legency method
      to sync CE and ME

      v2:
      Insert double SWITCH_BUFFER at front of vm flush as well.

      drm/amdgpu: unwind properly in amdgpu_cs_parser_init()

      The amdgpu_cs_parser_init() function doesn't clean up after itself but
      instead the caller uses a free everything function amdgpu_cs_parser_fini()
      on failure.  This style of error handling is often buggy.  In this
      example, we call "drm_free_large(parser->chunks[i].kdata);" when it is
      an unintialized pointer or when "parser->chunks" is NULL.

      I fixed this bug by adding unwind code so that it frees everything that
      it allocates.

      I also mode some other very minor changes:
      1) Renamed "r" to "ret".
      2) Moved the chunk_array allocation to the start of the function.
      3) Removed some initializers which are no longer needed.

      attempt to bind to an interface with fewer bulk endpoints would
      currently lead to an oops.

      Fixes CVE-2015-5257.

      Request allocation has been moved to connect_ring, which is called every
      time blkback connects to the frontend (this can happen multiple times 
during
      a blkback instance life cycle). On the other hand, request freeing has not
      been moved, so it's only called when destroying the backend instance. Due 
to
      this mismatch, blkback can allocate the request pool multiple times, 
without
      freeing it.

      In order to fix it, move the freeing of requests to xen_blkif_disconnect 
to
      restore the symmetry between request allocation and freeing.

      drm/i915/bios: handle MIPI Sequence Block v3+ gracefully

      The VBT MIPI Sequence Block version 3 has forward incompatible changes:

      First, the block size in the header has been specified reserved, and the
      actual size is a separate 32-bit value within the block. The current
      find_section() function to will only look at the size in the block
      header, and, depending on what's in that now reserved size field,
      continue looking for other sections in the wrong place.

      Fix this by taking the new block size field into account. This will
      ensure that the lookups for other sections will work properly, as long
      as the new 32-bit size does not go beyond the opregion VBT mailbox size.

      Second, the contents of the block have been completely
      changed. Gracefully refuse parsing the yet unknown data version.

      If we send a layoutreturn asynchronously before close, the close
      might reach server first and layoutreturn would fail with BADSTATEID

      cxl: Fix lockdep warning while creating afu_err_buff attribute

      Presently a lockdep warning is reported during creation of afu_err_buff
      bin_attribute for the afu. This is caused due to the variable attr.key
      not pointing to a static class key, hence the function lockdep_init_map
      reports this warning:

       BUG: key <some-address> not in .data!

      The patch fixes this issue by calling sysfs_attr_init on the
      attr_eb.attr structure before populating it with the afu_err_buff file
      details. This will populate the attr.key variable with a static class
      key so that lockdep_init_map stops complaining about the lockdep key not
      being static.

      READ_ONCE_CTRL() semantics.

      This patch makes sure that atomic_{read,set}() are at least

      We already had the 'requirement' that atomic_read() should use

      All are now converted to use READ_ONCE().

      And, by a symmetry and general paranoia argument, upgrade atomic_set()

      locking/lockdep: Fix hlock->pin_count reset on lock stack rebuilds

      Various people reported hitting the "unpinning an unpinned lock"
      warning. As it turns out there are 2 places where we take a lock out
      of the middle of a stack, and in those cases it would fail to preserve
      the pin_count when rebuilding the lock stack.

      drm/i915: workaround bad DSL readout v3

      On HSW at least (still testing other platforms, but should be harmless
      elsewhere), the DSL reg reads back as 0 when read around vblank start
      time.  This ends up confusing the atomic start/end checking code, since
      it causes the update to appear as if it crossed a frame count boundary.
      Avoid the problem by making sure we don't return scanline_offset from
      the get_crtc_scanline function.  In moving the code there, I add to add
      an additional delay since it could be called and have a legitimate 0
      result for some time (depending on the pixel clock).

      v2: move hsw dsl read hack to get_crtc_scanline (Ville)
      v3: use break instead of goto (Ville)
          update comment with workaround details (Ville)

      perf record: Synthesize COMM event for a command line workload

      When perf creates a new child to profile, the events are enabled on
      exec().  And in this case, it doesn't synthesize any event for the
      child since they'll be generated during exec().  But there's an window
      between the enabling and the event generation.

      It used to be overcome since samples are only in kernel (so we always
      have the map) and the comm is overridden by a later COMM event.
      However it won't work if events are processed and displayed before the
      COMM event overrides like in 'perf script'.  This leads to those early
      samples (like native_write_msr_safe) not having a comm but pid (like
      ':15328').

      So it needs to synthesize COMM event for the child explicitly before
      enabling so that it can have a correct comm.  But at this time, the
      comm will be "perf" since it's not exec-ed yet.

      Committer note:

      tools vm: Fix build due to removal of tools/lib/api/fs/debugfs.h

      lib: fix data race in rhashtable_rehash_one

      rhashtable_rehash_one() uses complex logic to update entry->next field,
      after INIT_RHT_NULLS_HEAD and NULLS_MARKER expansion:

      entry->next = 1 | ((base + off) << 1)

      This can be compiled along the lines of:

      entry->next = base + off
      entry->next <<= 1
      entry->next |= 1

      Which will break concurrent readers.

      NULLS value recomputation is not needed here, so just remove
      the complex logic.

      The data race was found with KernelThreadSanitizer (KTSAN).

      openvswitch: Zero flows on allocation.

      When support for megaflows was introduced, OVS needed to start
      installing flows with a mask applied to them. Since masking is an
      expensive operation, OVS also had an optimization that would only
      take the parts of the flow keys that were covered by a non-zero
      mask. The values stored in the remaining pieces should not matter
      because they are masked out.

      While this works fine for the purposes of matching (which must always
      look at the mask), serialization to netlink can be problematic. Since
      the flow and the mask are serialized separately, the uninitialized
      portions of the flow can be encoded with whatever values happen to be
      present.

      In terms of functionality, this has little effect since these fields
      will be masked out by definition. However, it leaks kernel memory to
      userspace, which is a potential security vulnerability. It is also
      possible that other code paths could look at the masked key and get
      uninitialized data, although this does not currently appear to be an
      issue in practice.

      This removes the mask optimization for flows that are being installed.
      This was always intended to be the case as the mask optimizations were
      really targetting per-packet flow operations.

      net: dsa: actually force the speed on the CPU port

      Commit 54d792f257c6 ("net: dsa: Centralise global and port setup
      code into mv88e6xxx.") merged in the 4.2 merge window broke the link
      speed forcing for the CPU port of Marvell DSA switches.  The original
      code was:

              /* MAC Forcing register: don't force link, speed, duplex
               * or flow control state to any particular values on physical
               * ports, but force the CPU port and all DSA ports to 1000 Mb/s
               * full duplex.
               */
              if (dsa_is_cpu_port(ds, p) || ds->dsa_port_mask & (1 << p))
                      REG_WRITE(addr, 0x01, 0x003e);
              else
                      REG_WRITE(addr, 0x01, 0x0003);

      but the new code does a read-modify-write:

                      reg = _mv88e6xxx_reg_read(ds, REG_PORT(port), 
PORT_PCS_CTRL);
                      if (dsa_is_cpu_port(ds, port) ||
                          ds->dsa_port_mask & (1 << port)) {
                              reg |= PORT_PCS_CTRL_FORCE_LINK |
                                      PORT_PCS_CTRL_LINK_UP |
                                      PORT_PCS_CTRL_DUPLEX_FULL |
                                      PORT_PCS_CTRL_FORCE_DUPLEX;
                              if (mv88e6xxx_6065_family(ds))
                                      reg |= PORT_PCS_CTRL_100;
                              else
                                      reg |= PORT_PCS_CTRL_1000;

      The link speed in the PCS control register is a two bit field.  Forcing
      the link speed in this way doesn't ensure that the bit field is set to
      the correct value - on the hardware I have here, the speed bitfield
      remains set to 0x03, resulting in the speed not being forced to gigabit.

      We must clear both bits before forcing the link speed.

      Partially due to a pre-exising "thinko", the new metadata-based tx/rx

      tx/rx paths.  This patch removes the "thinko" (involving multiple
      ip_hdr assignments) on the rx path and corrects the ECN handling on
      both the rx and tx paths.

      e1000: remove dead e1000_init_eeprom_params calls

      The device probe method e1000_probe calls e1000_init_eeprom_params
      itself so there's no reason to call it again from e1000_do_write_eeprom
      or e1000_do_read_eeprom.

      The sentence above assumes that e1000_init_eeprom_params is effective.
      e1000_init_eeprom_params depends mostly on hw->mac_type and e1000_probe
      bails out early if it can't set mac_type (see e1000_init_hw_struct, then
      e1000_set_mac_type), qed.

      Btw, if effective, the removed paths would had been deadlock prone when
      e1000_eeprom_spi was set:
      -> e1000_write_eeprom (takes e1000_eeprom_lock)
         -> e1000_do_write_eeprom
            -> e1000_init_eeprom_params
               -> e1000_read_eeprom (takes e1000_eeprom_lock)

      (same narrative with e1000_read_eeprom -> e1000_do_read_eeprom etc.)

      As a final note, the candidate deadlock above can't happen in e1000_probe
      due to the way eeprom->word_size is set / tested.

      fm10k: create "correct" header for the remote end on connect

      When we connect to the mailbox, we insert a fake disconnect header so
      that the code does not see an invalid header and thus instantly error
      every time we bring up the mailbox. However, we incorrectly record the
      tail and head from the local perspective. Since the remote end shouldn't
      have anything for us, add a "create_fake_disconnect_hdr" function which
      inverts the TAIL and HEAD fields. This enables us to connect without any
      errors of either TAIL or HEAD incorrectness, and prevents creating
      extraneous error messages. This is necessary now since mbx_reset_work
      does not actually reset the Tx FIFO head and tail pointers, thus head
      and tail might not be equivalent on a reconnect.

      fm10k: drop transmitted messages in Tx FIFO as part of reset_work

      This patch fixes a corner case issue with the PF/VF mailbox code.
      Currently, fm10k_mbx_reset_work clears various state about the mailbox.
      However, it does not clear the Tx FIFO head/tail pointers. We can't
      simply clear these pointers as we unintentionally drop untransmitted
      messages without error.

      Doing nothing results in a possible phantom re-transmission of messages,
      since we leave tx.head and tx.tail intact, but clear the tx_pulled and
      tail_len values. This means that the PF could continuously re-send a
      message which triggers a reset in the VF. Upon reset, the VF will
      re-receive the same message after a reconnect.

      If we reset the tx.head and tx.tail pointers completely, we end up
      dropping some messages that were pending before connect. This results in
      missing LPORT_MSG_READY bits, and VFs will end up reporting no link.

      However, we can resolve both issues by simply incrementing head to
      account for the already transmitted messages, before we reset tx_pulled.
      We do this via the same logic as fm10k_mbx_head_pull.

      We account for the tail_len which includes all data not yet transmitted,
      once we account for the acked data which means re-reading the HEAD
      variable from the message header. Then, we drop messages until we've
      dropped more than the new tx_pulled value. At this point, resetting
      tail_len and tx_pulled, but not tx.head and tx.tail will result in
      prevention of the phantom message. It also prevents us from dropping
      untransmitted messages upon attempting to Tx into a connect or
      disconnect header.

      ocfs2/dlm: fix deadlock when dispatch assert master

      The order of the following three spinlocks should be:
      dlm_domain_lock < dlm_ctxt->spinlock < dlm_lock_resource->spinlock

      But dlm_dispatch_assert_master() is called while holding
      dlm_ctxt->spinlock and dlm_lock_resource->spinlock, and then it calls
      dlm_grab() which will take dlm_domain_lock.

      Once another thread (for example, dlm_query_join_handler) has already
      taken dlm_domain_lock, and tries to take dlm_ctxt->spinlock deadlock
      happens.

      x86, efi, kasan: #undef memset/memcpy/memmove per arch

      In not-instrumented code KASAN replaces instrumented memset/memcpy/memmove
      with not-instrumented analogues __memset/__memcpy/__memove.

      However, on x86 the EFI stub is not linked with the kernel.  It uses
      not-instrumented mem*() functions from arch/x86/boot/compressed/string.c

      So we don't replace them with __mem*() variants in EFI stub.

      On ARM64 the EFI stub is linked with the kernel, so we should replace
      mem*() functions with __mem*(), because the EFI stub runs before KASAN
      sets up early shadow.

      So let's move these #undef mem* into arch's asm/efi.h which is also
      included by the EFI stub.

      Also, this will fix the warning in 32-bit build reported by kbuild test
      robot:

        efi-stub-helper.c:599:2: warning: implicit declaration of function 
'memcpy'

      mm: migrate: hugetlb: putback destination hugepage to active list

      Since commit bcc54222309c ("mm: hugetlb: introduce page_huge_active")
      each hugetlb page maintains its active flag to avoid a race condition
      betwe= en multiple calls of isolate_huge_page(), but current kernel
      doesn't set the f= lag on a hugepage allocated by migration because the
      proper putback routine isn= 't called.  This means that users could
      still encounter the race referred to by bcc54222309c in this special
      case, so this patch fixes it.

      mm, dax: VMA with vm_ops->pfn_mkwrite wants to be write-notified

      For VM_PFNMAP and VM_MIXEDMAP we use vm_ops->pfn_mkwrite instead of
      vm_ops->page_mkwrite to notify abort write access.  This means we want
      vma->vm_page_prot to be write-protected if the VMA provides this vm_ops.

      A theoretical scenario that will cause these missed events is:

        On writable mapping with vm_ops->pfn_mkwrite, but without
        vm_ops->page_mkwrite: read fault followed by write access to the pfn.
        Writable pte will be set up on read fault and write fault will not be
        generated.

      I found it examining Dave's complaint on generic/080:

        http://lkml.kernel.org/g/20150831233803.GO3902@dastard

      Although I don't think it's the reason.

      It shouldn't be a problem for ext2/ext4 as they provide both pfn_mkwrite
      and page_mkwrite.

      On ppc big endian this check fails, the mutex doesn't necessarily need
      to be identical for all pages after pthread_mutex_lock/unlock cycles.
      The count verification (outside of the pthread_mutex_t structure)

      userfaultfd: revert "userfaultfd: waitqueue: add nr wake parameter to 
__wake_up_locked_key"

      This reverts commit 51360155eccb907ff8635bd10fc7de876408c2e0 and adapts
      fs/userfaultfd.c to use the old version of that function.

      It didn't look robust to call __wake_up_common with "nr == 1" when we
      absolutely require wakeall semantics, but we've full control of what we
      insert in the two waitqueue heads of the blocked userfaults.  No
      exclusive waitqueue risks to be inserted into those two waitqueue heads
      so we can as well stick to "nr == 1" of the old code and we can rely
      purely on the fact no waitqueue inserted in one of the two waitqueue
      heads we must enforce as wakeall, has wait->flags WQ_FLAG_EXCLUSIVE set.

      PCI: Clear IORESOURCE_UNSET when clipping a bridge window

      c770cb4cb505 ("PCI: Mark invalid BARs as unassigned") sets 
IORESOURCE_UNSET
      if we fail to claim a resource.  If we tried to claim a bridge window,
      failed, clipped the window, and tried to claim the clipped window, we
      failed again because of IORESOURCE_UNSET:

        pci_bus 0000:00: root bus resource [mem 0xc0000000-0xffffffff window]
        pci 0000:00:01.0: can't claim BAR 15 [mem 0xbdf00000-0xddefffff 64bit 
pref]: no compatible bridge window
        pci 0000:00:01.0: [mem size 0x20000000 64bit pref] clipped to [mem size 
0x1df00000 64bit pref]
        pci 0000:00:01.0:   bridge window [mem size 0x1df00000 64bit pref]
        pci 0000:00:01.0: can't claim BAR 15 [mem size 0x1df00000 64bit pref]: 
no address assigned

      The 00:01.0 window started as [mem 0xbdf00000-0xddefffff 64bit pref].  
That
      starts before the host bridge window [mem 0xc0000000-0xffffffff window], 
so
      we clipped the 00:01.0 window to [mem 0xc0000000-0xddefffff 64bit pref].
      But we left it marked IORESOURCE_UNSET, so the second claim failed when it
      should have succeeded.

      This means downstream devices will also fail for lack of resources, e.g.,
      in the bugzilla below,

        radeon 0000:01:00.0: Fatal error during GPU init

      Clear IORESOURCE_UNSET when we clip a bridge window.  Also clear
      IORESOURCE_UNSET in our copy of the unclipped window so we can see exactly
      what the original window was and how it now fits inside the upstream
      window.

      The NMI entry code that switches to the normal kernel stack needs to
      be very careful not to clobber any extra stack slots on the NMI
      stack.  The code is fine under the assumption that SWAPGS is just a
      normal instruction, but that assumption isn't really true.  Use
      SWAPGS_UNSAFE_STACK instead.

      This is part of a fix for some random crashes that Sasha saw.

      x86/paravirt: Replace the paravirt nop with a bona fide empty function

      PARAVIRT_ADJUST_EXCEPTION_FRAME generates this code (using nmi as an
      example, trimmed for readability):

          ff 15 00 00 00 00       callq  *0x0(%rip)        # 2796 <nmi+0x6>
                    2792: R_X86_64_PC32     pv_irq_ops+0x2c

      That's a call through a function pointer to regular C function that
      does nothing on native boots, but that function isn't protected
      against kprobes, isn't marked notrace, and is certainly not
      guaranteed to preserve any registers if the compiler is feeling
      perverse.  This is bad news for a CLBR_NONE operation.

      Of course, if everything works correctly, once paravirt ops are
      patched, it gets nopped out, but what if we hit this code before
      paravirt ops are patched in?  This can potentially cause breakage
      that is very difficult to debug.

      A more subtle failure is possible here, too: if _paravirt_nop uses
      the stack at all (even just to push RBP), it will overwrite the "NMI
      executing" variable if it's called in the NMI prologue.

      The Xen case, perhaps surprisingly, is fine, because it's already
      written in asm.

      Fix all of the cases that default to paravirt_nop (including
      adjust_exception_frame) with a big hammer: replace paravirt_nop with
      an asm function that is just a ret instruction.

      The Xen case may have other problems, so document them.

      This is part of a fix for some random crashes that Sasha saw.

      When sending IPIs, first check if the non-local part of the source and
      destination APIC IDs match; if so, send via the local APIC for efficiency.

      Secondly, since the AMD BIOS-kernel developer guide states IPI delivery
      will occur invarient of prior deliver status, avoid polling the delivery
      status bit for efficiency.

      cifs: use server timestamp for ntlmv2 authentication

      Linux cifs mount with ntlmssp against an Mac OS X (Yosemite
      10.10.5) share fails in case the clocks differ more than +/-2h:

      digest-service: digest-request: od failed with 2 proto=ntlmv2
      digest-service: digest-request: kdc failed with -1561745592 proto=ntlmv2

      Fix this by (re-)using the given server timestamp for the
      ntlmv2 authentication (as Windows 7 does).

      A related problem was also reported earlier by Namjae Jaen (see below):

      Windows machine has extended security feature which refuse to allow
      authentication when there is time difference between server time and
      client time when ntlmv2 negotiation is used. This problem is prevalent
      in embedded enviornment where system time is set to default 1970.

      Modern servers send the server timestamp in the TargetInfo Av_Pair
      structure in the challenge message [see MS-NLMP 2.2.2.1]
      In [MS-NLMP 3.1.5.1.2] it is explicitly mentioned that the client must
      use the server provided timestamp if present OR current time if it is
      not

      ====================
      Netfilter/IPVS updates for net-next

      The following patchset contains Netfilter/IPVS updates for your net-next 
tree
      in this 4.4 development cycle, they are:

      1) Schedule ICMP traffic to IPVS instances, this introduces a new 
schedule_icmp
         proc knob to enable/disable it. By default is off to retain the old
         behaviour. Patchset from Alex Gartrell.

      I'm also including what Alex originally said for the record:

      "The configuration of ipvs at Facebook is relatively straightforward.  All
      ipvs instances bgp advertise a set of VIPs and the network prefers the
      nearest one or uses ECMP in the event of a tie.  For the uninitiated, ECMP
      deterministically and statelessly load balances by hashing the packet
      (usually a 5-tuple of protocol, saddr, daddr, sport, and dport) and using
      that number as an index (basic hash table type logic).

      The problem is that ICMP packets (which contain really important
      information like whether or not an MTU has been exceeded) will get a
      different hash value and may end up at a different ipvs instance.  With no
      information about where to route these packets, they are dropped, creating
      ICMP black holes and breaking Path MTU discovery.  Suddenly, my mom's
      pictures can't load and I'm fielding midday calls that I want nothing to 
do
      with.

      To address this, this patch set introduces the ability to schedule icmp
      packets which is gated by a sysctl net.ipv4.vs.schedule_icmp.  If set to 
0,
      the old behavior is maintained -- otherwise ICMP packets are scheduled."

      2) Add another proc entry to ignore tunneled packets to avoid routing 
loops
         from IPVS, also from Alex.

      3) Fifteen patches from Eric Biederman to:

      * Stop passing nf_hook_ops as parameter to the hook and use the state hook
        object instead all around the netfilter code, so only the private data
        pointer is passed to the registered hook function.

      * Now that we've got state->net, propagate the netns pointer to netfilter 
hook
        clients to avoid its computation over and over again. A good example of 
how
        this has been simplified is the former TEE target (now nf_dup 
infrastructure)
        since it has killed the ugly pick_net() function.

      There's another round of netns updates from Eric Biederman making the 
line. To
      avoid the patchbomb again to almost all the networking mailing list (that 
is 84
      patches) I'd suggest we send you a pull request with no patches or let me 
know
      if you prefer a better way.

      x86/mm: Fix no-change case in try_preserve_large_page()

      try_preserve_large_page() checks if new_prot is the same as
      old_prot.  If so, it simply sets do_split to 0, and returns
      with no-operation.  However, old_prot is set as a 4KB pgprot
      value while new_prot is a large page pgprot value.

      Now that old_prot is initially set from p?d_pgprot() as a
      large page pgprot value, fix it by not overwriting old_prot
      with a 4KB pgprot value.

      x86/asm: Fix pud/pmd interfaces to handle large PAT bit

      Now that we have pud/pmd mask interfaces, which handle pfn & flags
      mask properly for the large PAT bit.

      Fix pud/pmd pfn & flags interfaces by replacing PTE_PFN_MASK and
      PTE_FLAGS_MASK with the pud/pmd mask interfaces.

      x86/asm: Add pud/pmd mask interfaces to handle large PAT bit

      The PAT bit gets relocated to bit 12 when PUD and PMD mappings are
      used.  This bit 12, however, is not covered by PTE_FLAGS_MASK, which
      is used for masking pfn and flags for all levels.

      Add pud/pmd mask interfaces to handle pfn and flags properly by using
      P?D_PAGE_MASK when PUD/PMD mappings are used, i.e. PSE bit is set.

      x86/asm: Move PUD_PAGE macros to page_types.h

      PUD_SHIFT is defined according to a given kernel configuration, which
      allows it be commonly used by any x86 kernels.  However, PUD_PAGE_SIZE
      and PUD_PAGE_MASK, which are set from PUD_SHIFT, are defined in
      page_64_types.h, which can be used by 64-bit kernel only.

      x86/vdso32: Define PGTABLE_LEVELS to 32bit VDSO

      In case of CONFIG_X86_64, vdso32/vclock_gettime.c fakes a 32-bit
      non-PAE kernel configuration by re-defining it to CONFIG_X86_32.
      However, it does not re-define CONFIG_PGTABLE_LEVELS leaving it
      as 4 levels.

      This mismatch leads <asm/pgtable_type.h> to NOT include <asm-generic/
      pgtable-nopud.h> and <asm-generic/pgtable-nopmd.h>, which will cause
      compile errors when a later patch enhances <asm/pgtable_type.h> to
      use PUD_SHIFT and PMD_SHIFT.  These -nopud & -nopmd headers define
      these SHIFTs for the 32-bit non-PAE kernel.

      Fix it by re-defining CONFIG_PGTABLE_LEVELS to 2 levels.

      MIPS: Fix FTLB detection for R6

      R6 removed the Config4.MMUExtDef field, with the low 16 bits only
      allowed to contain FTLB fields, and commit e87569cd6c57 ("MIPS:
      cpu-probe: Fix VTLB/FTLB configuration for R6") updated the probing of
      this field to assume an FTLB is always present for R6.

      However the FTLB may still be absent. The presence of those fields is
      actually specified by the MMU type in the Config.MT field, so use that
      (the new cpu_has_ftlb) to determine whether the FTLB is actually
      present.

      Add cpu_has_ftlb, which specifies that an FTLB is present in addition to
      the VTLB, probed based on whether Config.MT == 4 (rather than 1 for
      standard JTLB).

      This is necessary since MIPS release 6 removes Config4.MMUExtDef, so the
      presence of the FTLB fields in Config4 must be determined from Config.MT
      instead.

      Btrfs: keep dropped roots in cache until transaction commit

      When dropping a snapshot we need to account for the qgroup changes.  If 
we drop
      the snapshot in all one go then the backref code will fail to find blocks 
from
      the snapshot we dropped since it won't be able to find the root in the fs 
root
      cache.  This can lead to us failing to find refs from other roots that 
pointed
      at blocks in the now deleted root.  To handle this we need to not remove 
the fs
      roots from the cache until after we process the qgroup operations.  Do 
this by
      adding dropped roots to a list on the transaction, and letting the 
transaction
      remove the roots at the same time it drops the commit roots.  This will 
keep all
      of the backref searching code in sync properly, and fixes a problem Mark 
was
      seeing with snapshot delete and qgroups.  Thanks,

      iommu/io-pgtable-arm: Don't use dma_to_phys()

      In checking whether DMA addresses differ from physical addresses, using
      dma_to_phys() is actually the wrong thing to do, since it may hide any
      DMA offset, which is precisely one of the things we are checking for.
      Simply casting between the two address types, whilst ugly, is in fact
      the appropriate course of action. Further care (and ugliness) is also
      necessary in the comparison to avoid truncation if phys_addr_t and
      dma_addr_t differ in size.

      We can also reject any device with a fixed DMA offset up-front at page
      table creation, leaving the allocation-time check for the more subtle
      cases like bounce buffering due to an incorrect DMA mask.

      Furthermore, we can then fix the hackish KConfig dependency so that
      architectures without a dma_to_phys() implementation may still
      COMPILE_TEST (or even use!) the code. The true dependency is on the
      DMA API, so use the appropriate symbol for that.

      tty: serial: Add missing module license for 8250_base.ko

      The split of the 8250 driver into a 8250_base/8250.ko resulted in a
      lack of a license for the 8250_base.ko module. This caused the module
      to fail to load and the kernel to be tainted. Add the appropriate
      MODULE_LICENSE to 8250_port.c, which is always compiled into
      8250_base.ko

      Commit 3adeb2566b9b ("MIPS: Loongson: Improve LEFI firmware interface")
      made the number of UARTs dynamic if LEFI_FIRMWARE_INTERFACE is configured.
      Unfortunately, it did not initialize the number of UARTs if
      LEFI_FIRMWARE_INTERFACE is not configured. As a result, the Fulong2e
      system has no console.

      tools lib traceevent: Fix string handling in heterogeneous arch 
environments

      When a trace recorded on a 32-bit device is processed with a 64-bit
      binary, the higher 32-bits of the address need to ignored.

      The lack of this results in the output of the 64-bit pointer
      value to the trace as the 32-bit address lookup fails in find_printk().

      Before:

        burn-1778  [003]   548.600305: bputs:   0xc0046db2s: 2cec5c058d98c

      After:

        burn-1778  [003]   548.600305: bputs:   0xc0046db2s: RT throttling 
activated

      The problem occurs in PRINT_FIELD when the field is recognized as a
      pointer to a string (of the type const char *)

      Heterogeneous architectures cases below can arise and should be handled:

      * Traces recorded using 32-bit addresses processed on a 64-bit machine
      * Traces recorded using 64-bit addresses processed on a 32-bit machine

      futex: Force hot variables into a single cache line

      futex_hash() references two global variables: the base pointer
      futex_queues and the size of the array futex_hashsize. The latter is
      marked __read_mostly, while the former is not, so they are likely to
      end up very far from each other. This means that futex_hash() is
      likely to encounter two cache misses.

      We could mark futex_queues as __read_mostly as well, but that doesn't
      guarantee they'll end up next to each other (and even if they do, they
      may still end up in different cache lines). So put the two variables
      in a small singleton struct with sufficient alignment and mark that as
      __read_mostly.

      tools lib bpf: Use FEATURE_USER to allow building in the same dir as perf

      When building tools/lib/bpf as part of the tools/perf/ build process,
      which will happend when we introduce a patch wiring that up, we end up
      stomping on the feature detection caching mechanism, that uses a file in
      the output directory (O=) that is shared by libbpf and perf to check if
      something changed from one build to another that requires redoing the
      feature detection process.

      By using the recently introduced FEATURE_USER tools/build/ knob, we can
      avoid that:

      Before, every make invokation would run the feature detection:

        $ make O=/tmp/build/perf -C tools/perf
        make: Entering directory '/home/git/linux/tools/perf'
        Auto-detecting system features:
        ...                         dwarf: [ on  ]
        ...                         glibc: [ on  ]
        <SNIP>
        ...                     get_cpuid: [ on  ]
        ...                           bpf: [ on  ]

          GEN      perf-archive
          GEN      perf-with-kcore

        Auto-detecting system features:
        ...                        libelf: [ on  ]
        ...                           bpf: [ on  ]
        <SNIP>

      After:

        $ make O=/tmp/build/perf -C tools/perf
        make: Entering directory '/home/git/linux/tools/perf'
          BUILD:   Doing 'make -j4' parallel build
        make: Leaving directory '/home/git/linux/tools/perf'
        $

      Because we now have two different feature detection state files:

        $ ls -la /tmp/build/perf/FEATURE-DUMP*
        -rw-rw-r--. 1 acme acme 338 Sep 21 17:25 /tmp/build/perf/FEATURE-DUMP
        -rw-rw-r--. 1 acme acme  33 Sep 21 17:25

      tools build: Allow setting the feature detection user

      We will use the tools/build/ autodetection in the eBPF patchkit
      and it is currently sharing the output directory with perf, that
      also uses the feature detection logic.

      As we keep state in the output directory, so that we can avoid running
      all the tests again, we need to have different filenames for the files
      used in this state, allow doing that via the FEATURE_USER variable, to
      be set alongside the existing FEATURE_{TEST,DISPLAY} variables.

      v2: Fix comment describing the FEATURE_DUMP filename to make sure where
          it is created, precisely at $(OUTPUT)FEATURE-DUMP$(FEATURE_USER).

      tools lib bpf: Fix up FEATURE_{TESTS,DISPLAY} usage

      When libbpf was introduced it wrongly asked for the "libelf" and "bpf"
      feature tests to be performed (via FEATURE_TESTS), while asking that
      "libbpf", "libelf-mmap", "libelf-getphdrnum" and "bpf" to have the
      result of its respective tests to be displayed (via FEATURE_DISPLAY).

      Due to another recently bug fixed in the tools/build/ infrastructure
      ("tools build: Fixup feature detection display function name") the
      results for the entries in the FEATURE_DISPLAY, for this case, were
      appearing as all succeeding, when two of them (the ones only on the
      DISPLAY) were not even being performed.

      Before:

        $ make -C tools/lib/bpf/
        make: Entering directory '/home/git/linux/tools/lib/bpf'
        Auto-detecting system features:
        ...                        libelf: [ on  ]
        ...             libelf-getphdrnum: [ OFF ]
        ...                   libelf-mmap: [ OFF ]
        ...                           bpf: [ on  ]
        <SNIP>

      After, with FEATURE_TESTS == FEATURE_DISPLAY:

        Auto-detecting system features:
        ...                        libelf: [ on  ]
        ...             libelf-getphdrnum: [ on  ]
        ...                   libelf-mmap: [ on  ]
        ...                           bpf: [ on  ]
        <SNIP>

      I just inverted, so that it tests the four features but displays just
      the libelf and mmap ones, to make it more compact. So it becomes:

        $ make -C tools/lib/bpf/
        make: Entering directory '/home/git/linux/tools/lib/bpf'

        Auto-detecting system features:
        ...                        libelf: [ on  ]
        ...                           bpf: [ on  ]

      timers: Fix data race in timer_stats_account_timer()

      timer_stats_account_timer() reads timer->start_site, then checks it
      for NULL and then re-reads it again, while
      timer_stats_timer_clear_start_info() can concurrently reset
      timer->start_site to NULL. This should not lead to crashes, but can
      double number of entries in timer stats as start_site is used during
      comparison, the doubled entries will have unuseful NULL start_site.

      Read timer->start_site only once in timer_stats_account_timer().

      The data race was found with KernelThreadSanitizer (KTSAN).

      mac80211: reset CQM history upon reconfiguration

      The current behavior of notifying CQM events is inconsistent:
      Upon first configuration there is a cqm event with the current
      status according to threshold configured, regardless of signal
      stability.
      When there is reconfiguration no event is sent unless there is
      a significant change to the signal level according to the new
      configuration.

      Since the current reconfiguration behavior might cause missing
      CQM events in case the current signal did not change but is on
      the other side of the new threshold, fix that by resetting the
      stored signal level upon reconfiguration.

      mac80211: remove direct probe step before authentication

      The direct probe step before authentication was done mostly for
      two reasons:
       1) the BSS data could be stale
       2) the beacon might not have included all IEs

      The concern (1) doesn't really seem to be relevant any more as
      we time out BSS information after about 30 seconds, and in fact
      the original patch only did the direct probe if the data was
      older than the BSS timeout to begin with. This condition got
      (likely inadvertedly) removed later though.

      Analysing this in more detail shows that since we mostly use
      data from the association response, the only real reason for
      needing the probe response was that the code validates the WMM
      parameters, and those are optional in beacons. As the previous
      patches removed that behaviour, we can now remove the direct
      probe step entirely.

      mac80211: process skb_queue while scanning in HW

      Queued frames aren't processed during scan, which results in an inability
      to complete the BA session establishment until the scan ends. Since we
      can't tx frames until the BA agreement setup is complete, it might result
      in a very large latency during scan.
      Fix this by allowing to process queued skbs while scanning in HW. This
      should be ok since the devices which support hw scan should be able
      to handle tx/rx while scanning.
      During SW scan, mac80211 drops any txed frames besides probes and NDPs,
      so it is still needed to delay processing of the queued frames till the
      SW scan is done.

      genirq: Handle force threading of irqs with primary and thread handler

      Force threading of interrupts does not really deal with interrupts
      which are requested with a primary and a threaded handler. The current
      policy is to leave them alone and let the primary handler run in
      interrupt context, but we set the ONESHOT flag for those interrupts as
      well.

      Kohji Okuno debugged a problem with the SDHCI driver where the
      interrupt thread waits for a hardware interrupt to trigger, which can't
      work well because the hardware interrupt is masked due to the ONESHOT
      flag being set. He proposed to set the ONESHOT flag only if the
      interrupt does not provide a thread handler.

      Though that does not work either because these interrupts can be
      shared. So the other interrupt would rightfully get the ONESHOT flag
      set and therefor the same situation would happen again.

      To deal with this proper, we need to force thread the primary handler
      of such interrupts as well. That means that the primary interrupt
      handler is treated as any other primary interrupt handler which is not
      marked IRQF_NO_THREAD. The threaded handler becomes a separate thread
      so the SDHCI flow logic can be handled gracefully.

      The same issue was reported against 4.1-rt.

      mrf24j40: change irq trigger type behaviour

      For rising edge triggered irq's the mrf24j40 can't deal with that, this
      races at position of tx completion irq, while the irq is disabled we
      readout the irq status registers. This will resets the irq line so other

      disabled and edge triggered interrupts will be ignored.

      mrf24j40: rework tx handling to async tx handling

      This patch reworks the current transmit API to spi_async handling. We
      removed the error handling check, because mac802154 has no chance to
      report it. Also the transmit timeout handling can't be handled by xmit
      async handling, for this usecase we need to implement the netdev
      watchdog. These are all unlikely cases which we drop now and should be
      provided by netdev watchdog.

      We also drop the bit setting for TXNACKREQ at register TXNCON, this is
      not necessary. The TXNCON register should set only once for each frame,
      previous settings doesn't matter.

      at86rf230: support edge triggered irq

      This patch adds support for edge triggered irq types. We remove the
      locking for irq resources by enable/disable irq and allocate directly
      some heap buffer at isr. We have still a enable/disable irq path but
      this is for level-triggered irq's which need to be disabled until
      spi_async clear the irq line.

      There is usually a little race condition between "irq line cleared" and
      "enable_irq". When in this time a edge triggered irq arrived, we will
      not recognize this interrupt. This case can't happend at at86rf230. The
      reason is that we unmask TRX_END irq's only which indicates a transmit
      or receive completion, which depends on the current state.

      On Transmit:

      TRX_END arrived and transceiver is in TX_ARET_ON state again, in this
      state no other TRX_END can happen until we leave the state.

      On Receive:

      This is protected with the RX_SAFE_MODE bit which leaves the transceiver
      in RX_AACK_BUSY until we readed the framebuffer. In this state no other
      TRX_END can happen.

      Tested with RPi where I first detected issues between edge/level irq's.

      ieee802154: change needed headroom/tailroom

      This patch cleanups needed_headroom, needed_tailroom and hard_header_len
      fields for wpan and lowpan interfaces.

      For wpan interfaces the worst case mac header len should be part of
      needed_headroom, currently this is set as hard_header_len, but
      hard_header_len should be set to the minimum header length which xmit
      call assumes and this is the minimum frame length of 802.15.4.
      The hard_header_len value will check inside send callbacl of AF_PACKET
      raw sockets.

      For lowpan interfaces, if fragmentation isn't needed the skb will
      call dev_hard_header for 802154 layer and queue it afterwards. This
      happens without new skb allocation, so we need the same headroom and
      tailroom lengths like 802154 inside 802154 6lowpan layer. At least we
      assume as minimum header length an ipv6 header size.

      generic one, which is also used by e.g. DGRAM AF_PACKET sockets, we
      can't make this callback structure 802.15.4 specific which is currently
      is.

      I saw the smallest "constraint" for calling this callback with
      dev_hard_header/dev_parse_header by AF_PACKET which assign a 8 byte
      array for address void pointers. Currently 802.15.4 specific protocols
      like af802154 and 6LoWPAN will assign the "struct ieee802154_addr" as
      these parameters which is greater than 8 bytes. The current callback
      implementation for header_ops.create assumes always a complete
      "struct ieee802154_addr" which AF_PACKET can't never handled and is
      greater than 8 bytes.

      For that reason we introduce now a "generic" create/parse header_ops
      callback which allows handling with intra-pan extended addresses only.
      This allows a small use-case with AF_PACKET to send "somehow" a valid
      dataframe over DGRAM.

      To keeping the current dev_hard_header behaviour we introduce a similar
      callback structure "wpan_dev_header_ops" which contains 802.15.4 specific
      upper-layer header creation functionality, which can be called by
      wpan_dev_hard_header.

      ieee802154: header_ops: fix frame control setting

      Sometimes upper-layer protocols wants to generate a new mac header by
      filling "struct ieee802154_hdr" only. These upper-layers sets for the
      address settings the source and dest fields, but not the fc fields for
      indicate the source and dest address mode. This patch changes the
      "ieee802154_hdr_push" function so the fc address fields are set
      according the source and dest fields of "struct ieee802154_hdr".

      ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000

      There is a 12MB unused region in our memory map between the vmalloc and
      fixmap areas. This became unused with commit e9da6e9905e6, confirmed
      with commit 64d3b6a3f480.

      We also have a 8MB guard area before the vmalloc area.  With the default
      240MB vmalloc area size and the current VMALLOC_END definition, that
      means the end of low memory ends up at 0xef800000 which is unfortunate
      for 768MB machines where 8MB of RAM is lost to himem.

      Let's move VMALLOC_END to 0xff800000 so the guard area won't chop the
      top of the 768MB low memory area while keeping the default vmalloc area
      size unchanged and still preserving a gap between the vmalloc and fixmap
      areas.

      ARM: 8430/1: use default ioremap alignment for SMP or LPAE

      16MB alignment for ioremap mappings was added by commit a069c896d0d6 
("[ARM]
      3705/1: add supersection support to ioremap()") in order to support 
supersection
      mappings. But __arm_ioremap_pfn_caller uses section and supersection 
mappings
      only in !SMP && !LPAE case. There is no need for such big alignment if 
either
      SMP or LPAE is enabled.

      After this change, ioremap will use default maximum alignment of 128 
pages.

      This patch adds imprecise abort enable/disable macros and uses them to
      enable imprecise aborts early when starting the kernel.

      This helps in tracking down the real cause for such imprecise abort, as
      they are handled as soon as they occur. Until now those aborts would
      only be enabled when entering the userspace and as a consequence crash
      the first userspace process if any abort had been raised during kernel
      startup.

      Some changes between xhci 0.96 and xhci 1.0 specifications forced us to
      check the hci version in code, some of these checks were implemented as
      hci_version == 1.0, which will not work with new xhci 1.1 controllers.

      xhci 1.1 behaves similar to xhci 1.0 in these cases, so change these

      usb: Use the USB_SS_MULT() macro to get the burst multiplier.

      Bits 1:0 of the bmAttributes are used for the burst multiplier.
      The rest of the bits used to be reserved (zero), but USB3.1 takes bit 7
      into use.

      Use the existing USB_SS_MULT() macro instead to make sure the mult value
      and hence max packet calculations are correct for USB3.1 devices.

      Note that burst multiplier in bmAttributes is zero based and that
      the USB_SS_MULT() macro adds one.

      usb: fixes for v4.3-rc3

      Here's the second pull request for current -rc cycle.

      A few fixes on dummy_hcd which have been around for
      longer than they should be.

      MUSB got a couple fixes, the most important of which
      is a fix to DMA channel teardown on AM335x devices.

      And DWC3 got a minor fix for when using RT-enabled
      kernels.

        these two patches can be reverted safely.

      tcp/dccp: fix timewait races in timer handling

      When creating a timewait socket, we need to arm the timer before
      allowing other cpus to find it. The signal allowing cpus to find
      the socket is setting tw_refcnt to non zero value.

      As we set tw_refcnt in __inet_twsk_hashdance(), we therefore need to
      call inet_twsk_schedule() first.

      This also means we need to remove tw_refcnt changes from
      inet_twsk_schedule() and let the caller handle it.

      Note that because we use mod_timer_pinned(), we have the guarantee
      the timer wont expire before we set tw_refcnt as we run in BH context.

      To make things more readable I introduced inet_twsk_reschedule() helper.

      When rearming the timer, we can use mod_timer_pending() to make sure
      we do not rearm a canceled timer.

      Note: This bug can possibly trigger if packets of a flow can hit
      multiple cpus. This does not normally happen, unless flow steering
      is broken somehow. This explains this bug was spotted ~5 months after
      its introduction.

      A similar fix is needed for SYN_RECV sockets in reqsk_queue_hash_req(),
      but will be provided in a separate patch for proper tracking.

      tcp: send loss probe after 1s if no RTT available

      This patch makes TLP to use 1 sec timer by default when RTT is
      not available due to SYN/ACK retransmission or SYN cookies.

      Prior to this change, the lack of RTT prevents TLP so the first
      data packets sent can only be recovered by fast recovery or RTO.
      If the fast recovery fails to trigger the RTO is 3 second when
      SYN/ACK is retransmitted. With this patch we can trigger fast
      recovery in 1sec instead.

      Note that we need to check Fast Open more properly. A Fast Open
      connection could be (accepted then) closed before it receives
      the final ACK of 3WHS so the state is FIN_WAIT_1. Without the
      new check, TLP will retransmit FIN instead of SYN/ACK.

      tcp: usec resolution SYN/ACK RTT

      Currently SYN/ACK RTT is measured in jiffies. For LAN the SYN/ACK
      RTT is often measured as 0ms or sometimes 1ms, which would affect
      RTT estimation and min RTT samping used by some congestion control.

      This patch improves SYN/ACK RTT to be usec resolution if platform
      supports it. While the timestamping of SYN/ACK is done in request
      sock, the RTT measurement is carefully arranged to avoid storing
      another u64 timestamp in tcp_sock.

      For regular handshake w/o SYNACK retransmission, the RTT is sampled
      right after the child socket is created and right before the request
      sock is released (tcp_check_req() in tcp_minisocks.c)

      For Fast Open the child socket is already created when SYN/ACK was
      sent, the RTT is sampled in tcp_rcv_state_process() after processing
      the final ACK an right before the request socket is released.

      If the SYN/ACK was retransmistted or SYN-cookie was used, we rely
      on TCP timestamps to measure the RTT. The sample is taken at the
      same place in tcp_rcv_state_process() after the timestamp values
      are validated in tcp_validate_incoming(). Note that we do not store
      TS echo value in request_sock for SYN-cookies, because the value
      is already stored in tp->rx_opt used by tcp_ack_update_rtt().

      One side benefit is that the RTT measurement now happens before
      initializing congestion control (of the passive side). Therefore
      the congestion control can use the SYN/ACK RTT.

      usbnet: New driver for QinHeng CH9200 devices

      There's a bunch of cheap USB 10/100 devices based on QinHeng chipsets. The
      vendor driver supports the CH9100 and CH9200 devices, but the majority of
      the code is of the if (ch9100) {} else {} form, with the most significant
      difference being that CH9200 provides a real MII interface but CH9100 
fakes
      one with a bunch of global variables and magic commands. I don't have a
      CH9100, so it's probably better if someone who does provides an 
independent
      driver for it. In any case, this is a lightly cleaned up version of the
      vendor driver with all the CH9100 code dropped.

      s390: qeth and iucv patches

      here is version 2 of some s390 related qeth patches for net-next. The 
patch by
      Thomas Richter adds a new feature to the qeth layer2 code; the remaining
      patches are minor improvements.
      Version 2 of patch 4 uses the desired indentation in function declarations
      and definitions spanning multiple lines in almost all cases. Thomas run 
into a
      conflict with the maximum number of columns once. Thus you will still see 
one
      function definition using an earlier column before the opening 
paranthesis.

      s390/iucv: do not use arrays as argument

      The iucv code uses arrays as arguments. Even though this does not
      really cause a problem, it could be misleading, since the compiler
      turns array arguments into just a pointer argument. To be more
      precise this patch changes the array arguments into pointers.

      qeth: add layer 2 RX/TX checksum offloading

      Checksum offloading for send and receive is already
      supported for layer 3 (IP layer). This patch
      adds support for RX and TX hardware checksum offloading
      for layer 2 (MAC layer). The hardware calculates the checksum
      for IP UDP and TCP packets.

      This patch moves the hardware checksum offloading setup
      to the set of common functions in qeth_core_main.c.
      Layer 2 and layer 3 now simply call the same common functions.

      Also note that TX checksum offloading is always enabled.
      The device driver relies on the TCP/IP stack to make use of
      this feature.

      perf probe: Fix a segfault when removing uprobe events

      Fix a segfault bug and a small mistake in perf probe -d.

      Since the "ulist" in perf_del_probe_events is never initialized,
      strlist__add(ulist, *) always causes a segfault when removing
      uprobe events by perf probe -d.

      Also, the "str" local variable is never released if fail to
      allocate the "klist". This fixes it too.

      This has been introduced by the commit e607f1426b58 ("perf probe:
      Print deleted events in cmd_probe()").

      This means that the inode had non-zero "outstanding extents" during
      eviction. This occurs because, during direct I/O a task which successfully
      used up its reserved data space would set BTRFS_INODE_DIO_READY bit and 
does
      not clear the bit after finishing the DIO write. A future DIO write could
      actually fail and the unused reserve space won't be freed because of the
      previously set BTRFS_INODE_DIO_READY bit.

      Clearing the BTRFS_INODE_DIO_READY bit in btrfs_direct_IO() caused the
      following issue,

      mtd: nand: sunxi: fix OOB handling in ->write_xxx() functions

      The USER_DATA register cannot be accessed using byte accessors on A13
      SoCs, thus triggering a bug when using memcpy_toio on this register.
      Declare an helper macros to convert an OOB buffer into a suitable
      USER_DATA value and vice-versa.

      This patch also fixes an error in the oob_required logic (some OOB data
      are not written even if the user required it) by removing the
      oob_required condition, which is perfectly valid since the core already
      fill ->oob_poi with FFs when oob_required is false.

      usb: gadget: dummy_hcd: in transfer(), return data sent, not limit

      dummy_timer uses transfer() to update transfer limit. However,
      limit passed to dummy_timer changes depending on transfer type,
      so the actual limit is overwritten.

      This can cause unpredictably slow / fast bulk transfers when
      coupled with control / interrupt transfers.

      Fix by returning actual amount of data sent in transfer() and
      substracting from total.

      usb: gadget: dummy_hcd: fix rescan logic for transfer

      transfer() schedules a rescan for transfers larger than
      maxpacket, which is wrong for transfers that are multiples
      of maxpacket.

      Rewrite to fix and clarify packet multiple / remainder
      transfer logic.

      usb: gadget: dummy_hcd: emulate sending zlp in packet logic

      currently, when a zlp flag is set and an urb/usb_request
      buffer is filled without a short packet, transfer() leaves
      its status at -EINPROGRESS and does not rescan for short
      packet.

      In a scenario where ep.maxpacket bytes are copied,
      URB_ZERO_PACKET is set, urb buffer is filled and usb_request
      buffer is not, transfer() returns with an urb with
      -EINPROGRESS status, which dummy_hcd treats as incomplete
      transfer.

      Check for zlp and rescan appropriately.

      crypto: marvell - properly handle CRYPTO_TFM_REQ_MAY_BACKLOG-flagged 
requests

      The mv_cesa_queue_req() function calls crypto_enqueue_request() to
      enqueue a request. In the normal case (i.e the queue isn't full), this
      function returns -EINPROGRESS. The current Marvell CESA crypto driver
      takes this into account and cleans up the request only if an error
      occured, i.e if the return value is not -EINPROGRESS.

      Unfortunately this causes problems with
      CRYPTO_TFM_REQ_MAY_BACKLOG-flagged requests. When such a request is
      passed to crypto_enqueue_request() and the queue is full,
      crypto_enqueue_request() will return -EBUSY, but will keep the request
      enqueued nonetheless. This situation was not properly handled by the
      Marvell CESA driver, which was anyway cleaning up the request in such
      a situation. When later on the request was taken out of the backlog
      and actually processed, a kernel crash occured due to the internal
      driver data structures for this structure having been cleaned up.

      To avoid this situation, this commit adds a
      mv_cesa_req_needs_cleanup() helper function which indicates if the
      request needs to be cleaned up or not after a call to
      crypto_enqueue_request(). This helper allows to do the cleanup only in
      the appropriate cases, and all call sites of mv_cesa_queue_req() are
      fixed to use this new helper function.

      crypto: tcrypt - avoid mapping from module image addresses

      The output buffer in test_ahash_speed will point to an address located
      within the tcrypt module image.
      This causes problems when trying to DMA map the buffer.
      For e.g. on ARM-based LS1021A, a page fault occurs within the
      DMA API when trying to access the struct page returned by
      virt_to_page(output):

      insmod tcrypt.ko mode=403

      testing speed of async sha1 (sha1-caam)

      netlink: Fix autobind race condition that leads to zero port ID

      The commit c0bb07df7d981e4091432754e30c9c720e2c0c78 ("netlink:
      Reset portid after netlink_insert failure") introduced a race
      condition where if two threads try to autobind the same socket
      one of them may end up with a zero port ID.  This led to kernel
      deadlocks that were observed by multiple people.

      This patch reverts that commit and instead fixes it by introducing
      a separte rhash_portid variable so that the real portid is only set
      after the socket has been successfully hashed.

      macvtap: fix TUNSETSNDBUF values > 64k

      Upon TUNSETSNDBUF,  macvtap reads the requested sndbuf size into
      a local variable u.
      commit 39ec7de7092b ("macvtap: fix uninitialized access on
      TUNSETIFF") changed its type to u16 (which is the right thing to
      do for all other macvtap ioctls), breaking all values > 64k.

      The value of TUNSETSNDBUF is actually a signed 32 bit integer, so
      the right thing to do is to read it into an int.

      These have roughly the same purpose as the SMRR, which we do not need
      to implement in KVM.  However, Linux accesses MSR_K8_TSEG_ADDR at
      boot, which causes problems when running a Xen dom0 under KVM.

      iptunnel: make rx/tx bytes counters consistent

      This was already done a long time ago in
      commit 64194c31a0b6 ("inet: Make tunnel RX/TX byte counters more 
consistent")
      but tx path was broken (at least since 3.10).

      Before the patch the gre header was included on tx.

      After the patch:
      $ ping -c1 192.168.0.121 ; ip -s l ls dev gre1

      Netfilter fixes for net

      The following patch contains Netfilter fixes for your net tree, they are:

      1) nf_log_unregister() should only set to NULL the logger that is being
         unregistered, instead of everything else. Patch from Florian Westphal.

      2) Fix a crash when accessing physoutdev from PREROUTING in br_netfilter.
         This is partially reverting the patch to shrink nf_bridge_info to 32 
bytes.
         Also from Florian.

      3) Use existing match/target extensions in the internal nft_compat 
extension
         lists when the extension is family unspecific (ie. NFPROTO_UNSPEC).

      4) Wait for rcu grace period before leaving nf_log_unregister().

      This reverts commit 1298267b548a78840bd4b3e030993ff8747ca5e6.

      That commit claim that the Vitesse VSC8641 is compatible with Vitesse
      82xx. But this is not true. It seems that all the registers used
      in Vitesse phy driver are not compatible between 8641 and 82xx.
      It does cause malfunction of the Ethernet on p1010rdb-pa board.
      So we definitely need a rework in order to support the 8641 phy
      in this driver.

      Intel Wired LAN Driver Updates 2015-09-17

      This series contains updates to i40e and i40evf.

      Shannon provides updates to i40e and i40evf to resolve an issue with the
      nvmupdate utility.  First renames a variable name to reduce confusion and
      to differentiate it from the actual user variable.  Then added the ability
      to save the admin queue write back descriptor if a caller supplies a
      buffer for it to be saved into.  Added a new GetStatus command so that
      the NVM update tool can query the current status instead of doing fake
      write requests to probe for readiness.  Added wait states to the NVM
      update state machine to signify when waiting for an update operation to
      finish, whether we are in the middle of a set of write operations, or we
      are now idle but waiting.  Then added a facility to run admin queue
      commands through the NVM update utility in order to allow the update
      tools to interact with the firmware and do special commands needed for
      updates and configuration changes.  Also added a facility to recover the
      result of a previously run admin queue command.

      net: Fix behaviour of unreachable, blackhole and prohibit routes

      Man page of ip-route(8) says following about route types:

        unreachable - these destinations are unreachable.  Packets are disâ??
        carded and the ICMP message host unreachable is generated.  The local
        senders get an EHOSTUNREACH error.

        blackhole - these destinations are unreachable.  Packets are disâ??
        carded silently.  The local senders get an EINVAL error.

        prohibit - these destinations are unreachable.  Packets are discarded
        and the ICMP message communication administratively prohibited is
        generated.  The local senders get an EACCES error.

      In the inet6 address family, this was correct, except the local senders
      got ENETUNREACH error instead of EHOSTUNREACH in case of unreachable 
route.
      In the inet address family, all three route types generated ICMP message
      net unreachable, and the local senders got ENETUNREACH error.

      In both address families all three route types now behave consistently
      with documentation.

      net: add Hisilicon Network Subsystem support (config and documents)

      The Hisilicon Network Subsystem is a long term evolution IP which is
      supposed to be used in Hisilicon ICT SoC. The IP, which is called hns
      for short, is a TCP/IP acceleration engine, which can directly decode
      TCP/IP stream and distribute them to different ring buffers.

      HNS can be configured to work on different mode for different scenario.
      This patch make use only some of the mode to make it as standard
      ethernet NIC. The other mode will be added soon.

      The whole function has 4 kernel sub-modules:

      hnae: the HNS acceleration engine framework. It provides a abstract
      interface between the engine and the upper layers which make use of the
      engine by ring buffer.

      hns_enet_drv: a standard ethernet driver that base on the ring buffer.

      hns_dsaf: one of the implementation of HNS acceleration engine, which is
      applied on Hililicon hip05, Hi1610 and other later-on SoCs

      hns_mdio: the mdio control to the PHY, used by acceleration engine

      This commit converts the rcu_data structure's ->cpu_no_qs field
      to a union.  The bytewise side of this union allows individual access
      to indications as to whether this CPU needs to find a quiescent state
      for a normal (.norm) and/or expedited (.exp) grace period.  The setwise
      side of the union allows testing whether or not a quiescent state is
      needed at all, for either type of grace period.

      For now, only .norm is used.  A later commit will introduce the expedited
      usage.

      An upcoming commit needs to invert the sense of the ->passed_quiesce
      rcu_data structure field, so this commit is taking this opportunity
      to clarify things a bit by renaming ->qs_pending to ->core_needs_qs.

      So if !rdp->core_needs_qs, then this CPU need not concern itself with
      quiescent states, in particular, it need not acquire its leaf rcu_node
      structure's ->lock to check.  Otherwise, it needs to report the next
      quiescent state.

      rcu: Move synchronize_sched_expedited() to combining tree

      Currently, synchronize_sched_expedited() uses a single global counter
      to track the number of remaining context switches that the current
      expedited grace period must wait on.  This is problematic on large
      systems, where the resulting memory contention can be pathological.
      This commit therefore makes synchronize_sched_expedited() instead use
      the combining tree in the same manner as synchronize_rcu_expedited(),
      keeping memory contention down to a dull roar.

      This commit creates a temporary function sync_sched_exp_select_cpus()
      that is very similar to sync_rcu_exp_select_cpus().  A later commit
      will consolidate these two functions, which becomes possible when
      synchronize_sched_expedited() switches from stop_one_cpu_nowait() to
      smp_call_function_single().

      in a preemptible-RCU read-side critical section, then waits for all the
      ->blkd_tasks lists to drain.  This works, but results in both an IPI and
      a double context switch even on CPUs that do not happen to be running
      in a preemptible RCU read-side critical section.

      This commit implements a new algorithm that causes less OS jitter.
      This new algorithm IPIs all online CPUs that are not idle (from an
      RCU perspective), but refrains from self-IPIs.  If a CPU receiving
      this IPI is not in a preemptible RCU read-side critical section (or
      is just now exiting one), it pushes quiescence up the rcu_node tree,
      otherwise, it sets a flag that will be handled by the upcoming outermost
      rcu_read_unlock(), which will then push quiescence up the tree.

      The expedited grace period must of course wait on any pre-existing blocked
      readers, and newly blocked readers must be queued carefully based on
      the state of both the normal and the expedited grace periods.  This
      new queueing approach also avoids the need to update boost state,
      courtesy of the fact that blocked tasks are no longer ever migrated to
      the root rcu_node structure.

      rcu: Move rcu_report_exp_rnp() to allow consolidation

      This is a nearly pure code-movement commit, moving rcu_report_exp_rnp(),
      sync_rcu_preempt_exp_done(), and rcu_preempted_readers_exp() so
      that later commits can make synchronize_sched_expedited() use them.
      The non-code-movement portion of this commit tags rcu_report_exp_rnp()
      as __maybe_unused to avoid build errors when CONFIG_PREEMPT=n.

      rcu: Use rsp->expedited_wq instead of sync_rcu_preempt_exp_wq

      Now that there is an ->expedited_wq waitqueue in each rcu_state structure,
      there is no need for the sync_rcu_preempt_exp_wq global variable.  This
      commit therefore substitutes ->expedited_wq for sync_rcu_preempt_exp_wq.
      It also initializes ->expedited_wq only once at boot instead of at the
      start of each expedited grace period.

      rcu: Suppress lockdep false positive for rcp->exp_funnel_mutex

      In kernels built with CONFIG_PREEMPT=y, synchronize_rcu_expedited()
      invokes synchronize_sched_expedited() while holding RCU-preempt's
      root rcu_node structure's ->exp_funnel_mutex, which is acquired after
      the rcu_data structure's ->exp_funnel_mutex.  The first thing that
      synchronize_sched_expedited() will do is acquire RCU-sched's rcu_data
      structure's ->exp_funnel_mutex.   There is no danger of an actual deadlock
      because the locking order is always from RCU-preempt's expedited mutexes
      to those of RCU-sched.  Unfortunately, lockdep considers both rcu_data
      structures' ->exp_funnel_mutex to be in the same lock class and therefore
      reports a deadlock cycle.

      This commit silences this false positive by placing RCU-sched's rcu_data
      structures' ->exp_funnel_mutex locks into their own lock class.

      Code like this in inline functions confuses some recent versions of gcc:

      For more details, see:

      This compiler bug results in the following failure after 114b7fd4b (rcu:

      NFSv4: Recovery of recalled read delegations is broken

      When a read delegation is being recalled, and we're reclaiming the
      cached opens, we need to make sure that we only reclaim read-only
      modes.
      A previous attempt to do this, relied on retrieving the delegation
      type from the nfs4_opendata structure. Unfortunately, as Kinglong
      pointed out, this field can only be set when performing reboot recovery.

      Furthermore, if we call nfs4_open_recover(), then we end up clobbering
      the state->flags for all modes that we're not recovering...

      The fix is to have the delegation recall code pass this information
      to the recovery call, and then refactor the recovery code so that
      nfs4_open_delegation_recall() does not need to call nfs4_open_recover().

kvmppc_h_logical_ci_load/store()

      Access to the kvm->buses (like with the kvm_io_bus_read() and -write()
      functions) has to be protected via the kvm->srcu lock.
      The kvmppc_h_logical_ci_load() and -store() functions are missing
      this lock so far, so let's add it there, too.
      This fixes the problem that the kernel reports "suspicious RCU usage"
      when lock debugging is enabled.

      preempted vcores list.  That way, we avoid leaving this vcpu's vcore
      on the preempted vcores list when the vcpu gets interrupted.

      thunderbolt: Allow loading of module on recent Apple MacBooks with 
thunderbolt 2 controller

      The pci device ids listed in the thunderbolt driver are to restrictive,
      which prevents the driver from being loaded on recent Apple MacBooks
      using a thunderbolt 2 controller. In particular this prevented any
      hot-plugging functionality for thunderbolt based ethernet dongles
      (i.e. Apples thunderbolt gigabit ethernet broadcom tg3 based dongle
      Model A1433 EMC 2590).

      Changing the subvendor and subdevice to PCI_ANY_ID the thunderbolt driver
      loads and binds to the pci device 07:00.0 System peripheral:
      Intel Corporation Device 156c which is the thunderbolt 2 controller on
      the MacBookPro12,1.

      Successfully tested on MacBookPro12,1. With the patch the thunderbolt
      module gets now loaded on boot. And it provides hot-plugging support both
      for a cold-plugged and a warm-plugged ethernet dongle.

      x86/entry/vsyscall: Add CONFIG to control default

      Most modern systems can run with vsyscall=none. In an effort to
      provide a way for build-time defaults to lack legacy settings,
      this adds a new CONFIG to select the type of vsyscall mapping to
      use, similar to the existing "vsyscall" command line parameter.

      thermal: power_allocator: exit early if there are no cooling devices

      Don't waste cycles in the power allocator governor's throttle function
      if there are no cooling devices and exit early.

      This commit doesn't change any functionality, but should provide better
      performance for the odd case of a thermal zone with trip points but
      without cooling devices.

         - Fix a CONFIG_ prefix bug in one of the ACPI drivers and make the

      Commit 505a666ee3fc ("writeback: plug writeback in wb_writeback() and
      writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes,
      which increases the merge rate when relatively contiguous small files
      are written by the filesystem.  It helps both on flash and spindles.

      For an fs_mark workload creating 4K files in parallel across 8 drives,
      this commit improves performance ~9% more by unplugging before calling
      cond_resched().  cond_resched() doesn't trigger an implicit unplug, so
      explicitly getting the IO down to the device before scheduling reduces
      latencies for anyone waiting on clean pages.

      It also cuts down on how often we use kblockd to unplug, which means
      less work bouncing from one workqueue to another.

      Many more details about how we got here:

      mm: fix type cast in __pfn_to_phys()

      The various definitions of __pfn_to_phys() have been consolidated to
      use a generic macro in include/asm-generic/memory_model.h. This hit
      mainline in the form of 012dcef3f058 "mm: move __phys_to_pfn and
      __pfn_to_phys to asm/generic/memory_model.h". When the generic macro
      was implemented the type cast to phys_addr_t was dropped which caused
      boot regressions on ARM platforms with more than 4GB of memory and
      LPAE enabled.

      It was suggested to use PFN_PHYS() defined in include/linux/pfn.h
      as provides the correct logic and avoids further duplication.

      netfilter: nf_tables: Pass struct net in nft_pktinfo

      nft_pktinfo is passed on the stack so this does not bloat any in core
      data structures.

      By centrally computing this information this makes maintence of the code
      simpler, and understading of the code easier.

      netfilter: x_tables: Pass struct net in xt_action_param

      As xt_action_param lives on the stack this does not bloat any
      persistent data structures.

      This is a first step in making netfilter code that needs to know
      which network namespace it is executing in simpler.

      netfilter: nf_tables: kill nft_pktinfo.ops

      - Add nft_pktinfo.pf to replace ops->pf
      - Add nft_pktinfo.hook to replace ops->hooknum

      This simplifies the code, makes it more readable, and likely reduces
      cache line misses.  Maintainability is enhanced as the details of
      nft_hook_ops are of no concern to the recpients of nft_pktinfo.

      inet netfilter: Prefer state->hook to ops->hooknum

      The values of nf_hook_state.hook and nf_hook_ops.hooknum must be the
      same by definition.

      We are more likely to access the fields in nf_hook_state over the
      fields in nf_hook_ops so with a little luck this results in
      fewer cache line misses, and slightly more consistent code.

      inet netfilter: Remove hook from ip6t_do_table, arp_do_table, ipt_do_table

      The values of ops->hooknum and state->hook are guaraneted to be equal
      making the hook argument to ip6t_do_table, arp_do_table, and
      ipt_do_table is unnecessary. Remove the unnecessary hook argument.

      In the callers use state->hook instead of ops->hooknum for clarity and
      to reduce the number of cachelines the callers touch.

      netfilter: ebtables: Simplify the arguments to ebt_do_table

      Nearly everything thing of interest to ebt_do_table is already present
      in nf_hook_state.  Simplify ebt_do_table by just passing in the skb,
      nf_hook_state, and the table.  This make the code easier to read and
      maintenance easier.

      To support this create an nf_hook_state on the stack in ebt_broute
      (the only caller without a nf_hook_state already available).  This new
      nf_hook_state adds no new computations to ebt_broute, but does use a
      few more bytes of stack.

      perf record: Avoid infinite loop at buildid processing with no samples

      If a session contains no events, we can get stuck in an infinite loop in
      __perf_session__process_events, with a non-zero file_size and 
data_offset, but
      a zero data_size.

      In this case, we can mmap the entirety of the file (consisting of the 
file and
      attribute headers), and fetch_mmaped_event will correctly refuse to read 
any
      (unmapped and non-existent) event headers. This causes
      __perf_session__process_events to unmap the file and retry with the exact 
same
      parameters, getting stuck in an infinite loop.

      This has been observed to result in an exit-time hang when counting
      rare/unschedulable events with perf record, and can be triggered 
artificially
      with the script below:

        ----
        #!/bin/sh
        printf "REPRO: launching perf\n";
        ./perf record -e software/config=9/ sleep 1 &
        PERF_PID=$!;
        sleep 0.002;
        kill -2 $PERF_PID;
        printf "REPRO: waiting for perf (%d) to exit...\n" "$PERF_PID";
        wait $PERF_PID;
        printf "REPRO: perf exited\n";
        ----

      To avoid this, have __perf_session__process_events bail out early when
      the file has no data (i.e. it has no events).

      Commiter note:

      I only managed to reproduce this when setting
      /proc/sys/kernel/kptr_restrict to '1' and changing the code to
      purposefully not process any samples and no synthesized samples, i.e.
      kptr_restrict prevents 'record' from synthesizing the kernel mmaps for
      vmlinux + modules and since it is a workload started from perf, we don't
      synthesize mmap/comm records for existing threads.

      Adrian Hunter managed to reproduce it in his environment tho.

      IB/hfi: Properly set permissions for user device files

      Some of the device files are required to be user accessible for PSM while
      most should remain accessible only by root.

      Add a parameter to hfi1_cdev_init which controls if the user should have 
access
      to this device which places it in a different class with the appropriate
      devnode callback.

      In addition set the devnode call back for the existing class to be a bit 
more
      explicit for those permissions.

      Finally remove the unnecessary null check before class_destroy

      kvm: svm: reset mmu on VCPU reset

      When INIT/SIPI sequence is sent to VCPU which before that
      was in use by OS, VMRUN might fail with:

       KVM: entry failed, hardware error 0xffffffff

       [...]
       EFER=0000000000000000

      with corresponding SVM error:
       KVM: FAILED VMRUN WITH VMCB:
       [...]
       cpl:            0                efer:         0000000000001000

       [...]

      What happens is that VCPU state right after offlinig:
      CR0: 0x80050033  EFER: 0xd01  CR4: 0x7e0
        -> long mode with CR3 pointing to longmode page tables

      and when VCPU gets INIT/SIPI following transition happens
      CR0: 0 -> 0x60000010 EFER: 0x0  CR4: 0x7e0
        -> paging disabled with stale CR3

      However SVM under the hood puts VCPU in Paged Real Mode*
      which effectively translates CR0 0x60000010 -> 80010010 after

         svm_vcpu_reset()
             -> init_vmcb()
                 -> kvm_set_cr0()
                     -> svm_set_cr0()

      but from  kvm_set_cr0() perspective CR0: 0 -> 0x60000010
      only caching bits are changed and
      commit d81135a57aa6
       ("KVM: x86: do not reset mmu if CR0.CD and CR0.NW are changed")'
      regressed svm_vcpu_reset() which relied on MMU being reset.

      As result VMRUN after svm_vcpu_reset() tries to run
      VCPU in Paged Real Mode with stale MMU context (longmode page tables),
      which causes some AMD CPUs** to bail out with VMEXIT_INVALID.

      Fix issue by unconditionally resetting MMU context
      at init_vmcb() time.

      sched: access local runqueue directly in single_task_running

      Commit 2ee507c47293 ("sched: Add function single_task_running to let a 
task
      check if it is the only task running on a cpu") referenced the current
      runqueue with the smp_processor_id.  When CONFIG_DEBUG_PREEMPT is enabled,
      that is only allowed if preemption is disabled or the currrent task is
      bound to the local cpu (e.g. kernel worker).

      With commit f78195129963 ("kvm: add halt_poll_ns module parameter") KVM
      calls single_task_running. If CONFIG_DEBUG_PREEMPT is enabled that
      generates a lot of kernel messages.

      To avoid adding preemption in that cases, as it would limit the 
usefulness,
      we change single_task_running to access directly the cpu local runqueue.

      s390: wire up separate socketcalls system calls

      As discussed on linux-arch all architectures should wire up the separate
      system calls that are hidden behind the socketcall multiplexer system 
call.

      It's just a couple more system calls and gives us a very small performance
      improvement.

      s390/compat: remove superfluous compat wrappers

      A couple of compat wrapper functions are simply trampolines to the real
      system call. This happened because the compat wrapper defines will only
      sign and zero extend system call parameters which are of different size
      on s390/s390x (longs and pointers).
      All other parameters will be correctly sign and zero extended by the
      normal system call wrappers.

      Bluetooth: Fix reporting incorrect EIR in device found mgmt event

      Some remote devices (ie Gigaset G-Tag) misbehave with ADV data length.
      This can lead to incorrect EIR format in device found event when
      ADV_DATA and SCAN_RSP are merged (terminator field before SCAN_RSP
      part).

      Fix this by inspecting ADV_DATA and correct its length if terminator
      is found.

      x86/asm/entry/32, selftests: Add 'test_syscall_vdso' test

      This new test checks that all x86 registers are preserved across
      32-bit syscalls. It tests syscalls through VDSO (if available)
      and through INT 0x80, normally and under ptrace.

      If kernel is a 64-bit one, high registers (r8..r15) are poisoned
      before the syscall is called and are checked afterwards.

      They must be either preserved, or cleared to zero (but r11 is
      special); r12..15 must be preserved for INT 0x80.

      EFLAGS is checked for changes too, but change there is not
      considered to be a bug (paravirt kernels do not preserve
      arithmetic flags).

      ath9k_htc: introduce support for different fw versions

      Current kernel support only one fw name with theoretically only one
      fw version located in â??firmware/htc_[9271|7010].fwâ??. Which is ok so 
far we
      have only one fw version (1.3). After we realised new fw 1.4, we faced
      compatibility problem which was decided to solve by firmware name and
      location:
      - new firmware is located now in
        firmware/ath9k_htc/htc_[9271|7010]-1.4.0.fw
      - old version 1.3 should be on old place, so old kernel have no issues
        with it.
      - new kernels including this patch should be able to try different
        supported (min..max) fw version.
      - new kernel should be able to support old fw location too. At least for
        now.

      At same time this patch will add new module option which should allow user
      to play with development  fw version without replacing stable one. If user
      will set â??ath9k_htc use_dev_fw=1â?? module will try to find
      firmware/ath9k_htc/htc_[9271|7010]-1.dev.0.fw first and if it fails, use
      stable version: for example...1.4.0.fw.

      sched/numa: Limit the amount of virtual memory scanned in task_numa_work()

      Currently task_numa_work() scans up to numa_balancing_scan_size_mb worth
      of memory per invocation, but only counts memory areas that have at
      least one PTE that is still present and not marked for numa hint faulting.

      It will skip over arbitarily large amounts of memory that are either
      unused, full of swap ptes, or full of PTEs that were already marked
      for NUMA hint faults but have not been faulted on yet.

      This can cause excessive amounts of CPU use, due to there being
      essentially no upper limit on the scan rate of very large processes
      that are not yet in a phase where they are actively accessing old
      memory pages (eg. they are still initializing their data).

      Avoid that problem by placing an upper limit on the amount of virtual
      memory that task_numa_work() scans in each invocation. This can be a
      higher limit than "pages", to ensure the task still skips over unused
      areas fairly quickly.

      While we are here, also fix the "nr_pte_updates" logic, so it only
      counts page ranges with ptes in them.

      perf: Fix races in computing the header sizes

      There are two races with the current code:

       - Another event can join the group and compute a larger header_size
         concurrently, if the smaller store wins we'll have an incorrect
         header_size set.

       - We compute the header_size after the event becomes active,
         therefore its possible to use the size before its computed.

      Remedy the first by moving the computation inside the ctx::mutex lock,
      and the second by placing it _before_ perf_install_in_context().

      Vince reported that its possible to overflow the various size fields
      and get weird stuff if you stick too many events in a group.

      Put a lid on this by requiring the fixed record size not exceed 16k.
      This is still a fair amount of events (silly amount really) and leaves
      plenty room for callchains and stack dwarves while also avoiding
      overflowing the u16 variables.

      perf/x86/intel: Make the CYCLE_ACTIVITY.* constraint on Broadwell more 
specific

      The counter constraint for CYCLE_ACTIVITY.* on Broadwell covered
      all CYCLE_ACTIVITY.* sub events, and forced them on counter 2.
      But actually only one sub event (umask 8) needs to be on counter 2,
      all others do not have any constraint.

      Only force that subevent. This fixes groups with multiple
      CYCLE_ACTIVITY.* events, for example:

        % perf stat -x, -e '{cpu/event=0xa3,umask=0x6,cmask=6/,\
        cpu/event=0xa2,umask=0x8/,\
        cpu/event=0xa3,umask=0x4,cmask=4/,cpu/event=0xb1,umask=0x1,cmask=1/}' 
true
        122150,,cpu/event=0xa3,umask=0x6,cmask=6/,846486,100.00
        16483,,cpu/event=0xa2,umask=0x8/,846486,100.00

      sched: Fix crash trying to dequeue/enqueue the idle thread

      Sasha reports that his virtual machine tries to schedule the idle
      thread since commit 6c37067e2786 ("sched: Change the
      sched_class::set_cpus_allowed() calling context").

      Hit trace shows this happening from idle_thread_get()->init_idle(),
      which is the _second_ init_idle() invocation on that task_struct, the
      first being done through idle_init()->fork_idle(). (this code is
      insane...)

      Because we call init_idle() twice in a row, its ->sched_class ==
      &idle_sched_class and ->on_rq = TASK_ON_RQ_QUEUED. This means
      do_set_cpus_allowed() think we're queued and will call dequeue_task(),
      which is implemented with BUG() for the idle class, seeing how
      dequeueing the idle task is a daft thing.

      Aside of the whole insanity of calling init_idle() _twice_, change the
      code to call set_cpus_allowed_common() instead as this is 'obviously'
      before the idle task gets ran etc..

      tcp_cubic: do not set epoch_start in the future

      Tracking idle time in bictcp_cwnd_event() is imprecise, as epoch_start
      is normally set at ACK processing time, not at send time.

      Doing a proper fix would need to add an additional state variable,
      and does not seem worth the trouble, given CUBIC bug has been there
      forever before Jana noticed it.

      Let's simply not set epoch_start in the future, otherwise
      bictcp_update() could overflow and CUBIC would again
      grow cwnd too fast.

      This was detected thanks to a packetdrill test Neal wrote that was flaky
      before applying this fix.

      Actually this is a bug.
      ep_shm_info[epidx].{es_status, zone} should be update
      inside for loop.

      This patch fixes this bug.

      vxlan: reject IPv6 addresses if IPv6 is not configured

      When IPv6 address is set without IPv6 configured, the vxlan socket is 
mostly
      treated as an IPv4 one but various lookus in fdb etc. still take the
      AF_INET6 into account. This creates incosistencies with weird 
consequences.

      Just reject IPv6 addresses in such case.

      vxlan: set needed headroom correctly

      vxlan_setup is called when allocating the net_device, i.e. way before
      vxlan_newlink (or vxlan_dev_configure) is called. This means
      vxlan->default_dst is actually unset in vxlan_setup and the condition that
      sets needed_headroom always takes the else branch.

      Set the needed_headrom at the point when we have the information about
      the address family available.

      Fixes: e4c7ed415387c ("vxlan: add ipv6 support")
      Fixes: 2853af6a2ea1a ("vxlan: use dev->needed_headroom instead of

      ARCNET: fix hard_header_len limit

      For arcnet the bare minimum header only contains the 4 bytes to
      specify source, dest and offset (1, 1 and 2 bytes respectively).
      The corresponding struct is struct arc_hardware.

      The struct archdr contains additionally a union of possible soft
      headers. When doing $insertusecasehere packets might well
      include short (or even no?) soft headers.

      For this reason only use arc_hardware instead of archdr to
      determine the hard_header_len for an arcnet device.

      net: bcmgenet: Implement RX coalescing control knobs

      Add support for the ethtool rx-frames coalescing parameter which allows
      defining the number of RX interrupts per frames received. The RDMA
      engine supports a configurable timeout with a resolution of
      approximately 8.192 us.

      We can no longer enable the BDONE/PDONE interrupts as those would
      fire for each packet/buffer received, which would defeat the MBDONE
      interrupt purpose. The MBDONE interrupt is guaranteed to correspond to a
      PDONE/BDONE interrupt when the threshold is set to 1.

      net: bcmgenet: Implement TX coalescing control knobs

      Configuring the ethtool tx-frames property, which translates into N
      packets before a TX interrupt is the simplest configuration scheme
      because it requires no locking neither at the softare nor hardware
      level, and is completely indepedent from the link speed. Since ethtool
      does not allow per-tx queue coalescing parameters, we apply the same
      setting to any transmit queue.

      We can no longer enable the BDONE/PDONE interrupts as those would fire
      for each packet/buffer received, which would defeat the MBDONE interrupt
      purpose. The MBDONE interrupt is guaranteed to correspond to a
      PDONE/BDONE interrupt when the threshold is set to 1, but offers
      interrupt coalescing when the value is > 1.

      Since the HW is configured to generate an interrupt when the ring
      becomes emtpy, we have to deny any timeout/timer settings coming from
      user-space to indicate we can only generate an interrupt very <N>
      packets.

      While we are at it, fix the DMA_INTR_THRESHOLD_MASK value which was off
      by one bit (0xff vs. 0x1ff).

      ipv6: ip6_fragment: fix headroom tests and skb leak

      David Woodhouse reports skb_under_panic when we try to push ethernet
      header to fragmented ipv6 skbs:

       skbuff: skb_under_panic: text:c1277f1e len:1294 put:14 head:dec98000
       data:dec97ffc tail:0xdec9850a end:0xdec98f40 dev:br-lan
      [..]
      ip6_finish_output2+0x196/0x4da

      David further debugged this:
        [..] offending fragments were arriving here with skb_headroom(skb)==10.
        Which is reasonable, being the Solos ADSL card's header of 8 bytes
        followed by 2 bytes of PPP frame type.

      The problem is that if netfilter ipv6 defragmentation is used, skb_cow()
      in ip6_forward will only see reassembled skb.

      Therefore, headroom is overestimated by 8 bytes (we pulled fragment
      header) and we don't check the skbs in the frag_list either.

      We can't do these checks in netfilter defrag since outdev isn't known yet.

      Furthermore, existing tests in ip6_fragment did not consider the fragment
      or ipv6 header size when checking headroom of the fraglist skbs.

      While at it, also fix a skb leak on memory allocation -- ip6_fragment
      must consume the skb.

      I tested this e1000 driver hacked to not allocate additional headroom
      (we end up in slowpath, since LL_RESERVED_SPACE is 16).

      If 2 bytes of headroom are allocated, fastpath is taken (14 byte
      ethernet header was pulled, so 16 byte headroom available in all
      fragments).

      The root cause is use of res.table uninitialized.

      Thanks to Nikolay for noticing the uninitialized use amongst the maze of
      gotos.

      As Nikolay pointed out the second initialization is not required to fix
      the oops, but rather to fix a related problem where a valid lookup should
      be invalidated before creating the rth entry.

      solos-pci: Increase headroom on received packets

      A comment in include/linux/skbuff.h says that:

       * Various parts of the networking layer expect at least 32 bytes of
       * headroom, you should not reduce this.

      This was demonstrated by a panic when handling fragmented IPv6 packets:
      http://marc.info/?l=linux-netdev&m=144236093519172&w=2

      It's not entirely clear if that comment is still valid â?? and if it is,
      perhaps netif_rx() ought to be enforcing it with a warning.

      But either way, it is rather stupid from a performance point of view
      for us to be receiving packets into a buffer which doesn't have enough
      room to prepend an Ethernet header â?? it means that *every* incoming
      packet is going to be need to be reallocated. So let's fix that.

      lib/string_helpers.c: fix infinite loop in string_get_size()

      Some string_get_size() calls (e.g.:
       string_get_size(1, 512, STRING_UNITS_10, ..., ...)
       string_get_size(15, 64, STRING_UNITS_10, ..., ...)
      ) result in an infinite loop. The problem is that if size is equal to
      divisor[units]/blk_size and is smaller than divisor[units] we'll end
      up with size == 0 when we start doing sf_cap calculations:

      For string_get_size(1, 512, STRING_UNITS_10, ..., ...) case:
         ...
         remainder = do_div(size, divisor[units]); -> size is 0, remainder is 1
         remainder *= blk_size; -> remainder is 512
         ...
         size *= blk_size; -> size is still 0
         size += remainder / divisor[units]; -> size is still 0

      The caller causing the issue is sd_read_capacity(), the problem was
      noticed on Hyper-V, such weird size was reported by host when scanning
      collides with device removal.  This is probably a separate issue worth
      fixing, this patch is intended to prevent the library routine from
      infinite looping.

      kasan: fix last shadow judgement in memory_is_poisoned_16()

      The shadow which correspond 16 bytes memory may span 2 or 3 bytes.  If
      the memory is aligned on 8, then the shadow takes only 2 bytes.  So we
      check "shadow_first_bytes" is enough, and need not to call
      "memory_is_poisoned_1(addr + 15);".  But the code "if
      (likely(!last_byte))" is wrong judgement.

      e.g.  addr=0, so last_byte = 15 & KASAN_SHADOW_MASK = 7, then the code
      will continue to call "memory_is_poisoned_1(addr + 15);"

      zram: fix possible use after free in zcomp_create()

      zcomp_create() verifies the success of zcomp_strm_{multi,single}_create()
      through comp->stream, which can potentially be pointing to memory that
      was freed if these functions returned an error.

      While at it, replace a 'ERR_PTR(-ENOMEM)' by a more generic
      'ERR_PTR(error)' as in the future zcomp_strm_{multi,siggle}_create()
      could return other error codes.  Function documentation updated
      accordingly.

      bpf: add bpf_redirect() helper

      Existing bpf_clone_redirect() helper clones skb before redirecting
      it to RX or TX of destination netdev.
      Introduce bpf_redirect() helper that does that without cloning.

      Benchmarked with two hosts using 10G ixgbe NICs.
      One host is doing line rate pktgen.
      Another host is configured as:
      $ tc qdisc add dev $dev ingress
      $ tc filter add dev $dev root pref 10 u32 match u32 0 0 flowid 1:2 \
         action bpf run object-file tcbpf1_kern.o section clone_redirect_xmit 
drop
      so it receives the packet on $dev and immediately xmits it on $dev + 1
      The section 'clone_redirect_xmit' in tcbpf1_kern.o file has the program
      that does bpf_clone_redirect() and performance is 2.0 Mpps

      $ tc filter add dev $dev root pref 10 u32 match u32 0 0 flowid 1:2 \
         action bpf run object-file tcbpf1_kern.o section redirect_xmit drop
      which is using bpf_redirect() - 2.4 Mpps

      and using cls_bpf with integrated actions as:
      $ tc filter add dev $dev root pref 10 \
        bpf run object-file tcbpf1_kern.o section redirect_xmit integ_act 
classid 1
      performance is 2.5 Mpps

      To summarize:
      u32+act_bpf using clone_redirect - 2.0 Mpps
      u32+act_bpf using redirect - 2.4 Mpps
      cls_bpf using redirect - 2.5 Mpps

      For comparison linux bridge in this setup is doing 2.1 Mpps
      and ixgbe rx + drop in ip_rcv - 7.8 Mpps

      cls_bpf: introduce integrated actions

      Often cls_bpf classifier is used with single action drop attached.
      Optimize this use case and let cls_bpf return both classid and action.
      For backwards compatibility reasons enable this feature under
      TCA_BPF_FLAG_ACT_DIRECT flag.

      Then more interesting programs like the following are easier to write:
      int cls_bpf_prog(struct __sk_buff *skb)
      {
        /* classify arp, ip, ipv6 into different traffic classes
         * and drop all other packets
         */
        switch (skb->protocol) {
        case htons(ETH_P_ARP):
          skb->tc_classid = 1;
          break;
        case htons(ETH_P_IP):
          skb->tc_classid = 2;
          break;
        case htons(ETH_P_IPV6):
          skb->tc_classid = 3;
          break;
        default:
          return TC_ACT_SHOT;
        }

        return TC_ACT_OK;

      tcp: provide skb->hash to synack packets

      In commit b73c3d0e4f0e ("net: Save TX flow hash in sock and set in skbuf
      on xmit"), Tom provided a l4 hash to most outgoing TCP packets.

      We'd like to provide one as well for SYNACK packets, so that all packets
      of a given flow share same txhash, to later enable bonding driver to
      also use skb->hash to perform slave selection.

      Note that a SYNACK retransmit shuffles the tx hash, as Tom did
      in commit 265f94ff54d62 ("net: Recompute sk_txhash on negative routing
      advice") for established sockets.

      This has nice effect making TCP flows resilient to some kind of black
      holes, even at connection establish phase.

      ====================
      Passing net through the netfilter hooks

      My primary goal with this patchset and it's follow ups is to cleanup the
      network routing paths so that we do not look at the output device to
      derive the network namespace.  My plan is to pass the network namespace
      of the transmitting socket through the output path, to replace code that
      looks at the output network device today.  Once that is done we can have
      routes with output devices outside of the current network namespace.
      Which should allow reception and transmission of packets in network
      namespaces to be as fast as normal packet reception and transmission
      with early demux disabled, because it will same code path.

      Once skb_dst(skb)->dev is a little better under control I think it will
      also be possible to use rcu to cleanup the ancient hack that sets
      dst->dev to loopback_dev when a network device is removed.

      The work to get there is a series of code cleanups.  I am starting with
      passing net into the netfilter hooks and into the functions that are
      called after the netfilter hooks.  This removes from netfilter the
      need to guess which network namespace it is working on.

      To get there I perform a series of minor prep patches so the big changes
      at the end are possible to audit without getting lost in the noise.  In
      particular I have a lot of patches computing net into a local variable
      and then using it through out the function.

      So this patchset encompases removing dead code, sorting out the _sk
      functions that were added last time someone pushed a prototype change
      through the post netfilter functions.  Cleaning up individual functions
      use of the network namespace.  Passing net into the netfilter hooks.
      Passing net into the post netfilter functions.  Using state->net in
      the netfilter code where it is available and trivially usable.

      Pablo, Dave I don't know whose tree this makes more sense to go
      through.  I am assuming at least initially Pablos as netfilter is
      involved.  From what I have seen there will be a lot of back and forth
      between the netfilter code paths and the routing code paths.

      The patches are also available (against 4.3-rc1) at:
      git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/net-next.git master

      netfilter: Pass net into okfn

      This is immediately motivated by the bridge code that chains functions 
that
      call into netfilter.  Without passing net into the okfns the bridge code 
would
      need to guess about the best expression for the network namespace to 
process
      packets in.

      As net is frequently one of the first things computed in continuation 
functions
      after netfilter has done it's job passing in the desired network 
namespace is in
      many cases a code simplification.

      To support this change the function dst_output_okfn is introduced to
      simplify passing dst_output as an okfn.  For the moment dst_output_okfn
      just silently drops the struct net.

      netfilter: Pass struct net into the netfilter hooks

      Pass a network namespace parameter into the netfilter hooks.  At the
      call site of the netfilter hooks the path a packet is taking through
      the network stack is well known which allows the network namespace to
      be easily and reliabily.

      This allows the replacement of magic code like
      "dev_net(state->in?:state->out)" that appears at the start of most
      netfilter hooks with "state->net".

      In almost all cases the network namespace passed in is derived
      from the first network device passed in, guaranteeing those
      paths will not see any changes in practice.

      The exceptions are:
      xfrm/xfrm_output.c:xfrm_output_resume()         xs_net(skb_dst(skb)->xfrm)
      ipvs/ip_vs_xmit.c:ip_vs_nat_send_or_cont()      ip_vs_conn_net(cp)
      ipvs/ip_vs_xmit.c:ip_vs_send_or_cont()          ip_vs_conn_net(cp)
      ipv4/raw.c:raw_send_hdrinc()                    sock_net(sk)
      ipv6/ip6_output.c:ip6_xmit()                      sock_net(sk)
      ipv6/ndisc.c:ndisc_send_skb()                   dev_net(skb->dev) not 
dev_net(dst->dev)
      ipv6/raw.c:raw6_send_hdrinc()                   sock_net(sk)
      br_netfilter_hooks.c:br_nf_pre_routing_finish() dev_net(skb->dev) before 
skb->dev is set to nf_bridge->physindev

      In all cases these exceptions seem to be a better expression for the
      network namespace the packet is being processed in then the historic
      "dev_net(in?in:out)".  I am documenting them in case something odd
      pops up and someone starts trying to track down what happened.

      net: Remove dev_queue_xmit_sk

      A function with weird arguments that it will never use to accomdate a
      netfilter callback prototype is absolutely in the core of the
      networking stack.  Frankly it does not make sense and it causes a lot
      of confusion as to why arguments that are never used are being passed
      to the function.

      As I am preparing to make a second change to arguments to the okfn even
      the names stops making sense.

      As I have removed the two callers of this function remove this confusion
      from the networking stack.

      ====================
      Intel Wired LAN Driver Updates 2015-09-15

      This series contains updates to ixgbe and fm10k.

      Don fixes a ixgbe issue by adding checks for systems that do not have
      SFP's to avoid incorrectly acting on interrupts that are falsely
      interpreted as SFP events.

      Alex Williamson adds a fix for ixgbe to disable SR-IOV prior to
      unregistering the netdev to avoid issues with guest OS's which do not
      support hot-unplug or their hot-unplug is broken.

      Alex Duyck update the lowest limit for adaptive interrupt interrupt
      moderation to about 12K interrupts per second for ixgbe.  This change
      increases the performance for ixgbe.  Also fixed up fm10k to remove
      the optimization that assumed that all fragments would be limited to
      page size, since that assumption is incorrect as the TCP allocator can
      provide up to a 32K page fragment.  Updated fm10k to add the MAC
      address to the list of values recorded on driver load.  Fixes fm10k
      so that we only trigger the data path reset if the fabric is ready to
      handle traffic to avoid triggering the reset unless the switch API is
      ready for us.

      Jacob updates the fm10k driver to disable the service task during
      suspend and re-enable it after we resume. If we don't do this, the
      device could be UP when you suspend and come back from resume as
      DOWN.  Also update fm10k to prevent the removal of default VID rules,
       and correctly remove the stack layers information of the VLAN, but then
      return to forwarding that VID as untagged frames.  If we deleted the VID
      rules here, we would begin dropping traffic due to VLAN membership
      violations.  Fixed fm10k to use pcie_get_minimum_link(), which is useful
      in cases where we connect to a slot at Gen3, but the slot is behind a bus
      which is only connected at Gen2.  Updated fm10k to update the netdev
      permanent address during reinit instead of up to enable users to
      immediately see the new MAC address on the VF even if the device is not
      up.  Adds the creation of VLAN interfaces on a device, even while the
      device is down for fm10k.  Fixed an issue where we request the incorrect
      MAC/VLAN combinations, and prevents us from accidentally reporting some
      frames as VLAN tagged.  Provided a couple of trivial fixes for fm10k
      to fix code style and typos in code comments.

      net: Fix vti use case with oif in dst lookups

      Steffen reported that the recent change to add oif to dst lookups breaks
      the VTI use case. The problem is that with the oif set in the flow struct
      the comparison to the nh_oif is triggered. Fix by splitting the
      FLOWI_FLAG_VRFSRC into 2 flags -- one that triggers the vrf device cache
      bypass (FLOWI_FLAG_VRFSRC) and another telling the lookup to not compare
      nh oif (FLOWI_FLAG_SKIP_NH_OIF).

      net-sysfs: get_netdev_queue_index() cleanup

      Redo commit ed1acc8cd8c22efa919da8d300bab646e01c2dce.

      Commit 822b3b2ebfff8e9b3d006086c527738a7ca00cd0 ("net: Add max rate tx 
queue
      attribute") moved get_netdev_queue_index around, but kept the old version.
      Probably because of a reuse of the original patch from before Eric's

      openvswitch: Fix IPv6 exthdr handling with ct helpers.

      Static code analysis reveals the following bug:

              net/openvswitch/conntrack.c:281 ovs_ct_helper()
              warn: unsigned 'protoff' is never less than zero.

      This signedness bug breaks error handling for IPv6 extension headers when
      using conntrack helpers. Fix the error by using a local signed variable.

      SUNRPC: Ensure that we wait for connections to complete before retrying

      Commit 718ba5b87343, moved the responsibility for unlocking the socket to
      xs_tcp_setup_socket, meaning that the socket will be unlocked before we
      know that it has finished trying to connect. The following patch is based 
on
      an initial patch by Russell King to ensure that we delay clearing the
      XPRT_CONNECTING flag until we either know that we failed to initiate
      a connection attempt, or the connection attempt itself failed.

      Failing to send a CLOSE if file is opened WRONLY and server reboots on a 
4.x mount

      A test case is as the description says:
      open(foobar, O_WRONLY);
      sleep()  --> reboot the server
      close(foobar)

      The bug is because in nfs4state.c in nfs4_reclaim_open_state() a few
      line before going to restart, there is
      clear_bit(NFS4CLNT_RECLAIM_NOGRACE, &state->flags).

      NFS4CLNT_RECLAIM_NOGRACE is a flag for the client states not open
      owner states. Value of NFS4CLNT_RECLAIM_NOGRACE is 4 which is the
      value of NFS_O_WRONLY_STATE in nfs4_state->flags. So clearing it wipes
      out state and when we go to close it, â??call_closeâ?? doesnâ??t get set 
as
      state flag is not set and CLOSE doesnâ??t go on the wire.

      of_pci_irq: Silence bogus "of_irq_parse_pci() failed ..." messages.

      It is perfectly legitimate for a PCI device to have an
      PCI_INTERRUPT_PIN value of zero.  This happens if the device doesn't
      use interrupts, or on PCIe devices, where only MSI/MSI-X are
      supported.

      Silence the annoying "of_irq_parse_pci() failed with rc=-19" error
      messages by moving the printing code into of_irq_parse_pci(), and only
      emitting the message for cases where PCI_INTERRUPT_PIN == 0 is not the
      cause for an early exit.

      so it makes sense to also have their bindings info in a single .txt.

      This commit extends the bma180 bindings with bma250 bindings, specifically
      it specifies how the 2 seperate interrupts the bma250 has must be listed
      in devicetree. The existing bma180 driver is already fully compatible
      with the specified bindings.

      of: thermal: Mark cooling-*-level properties optional

      The cooling-{min,max}-level properties are marked as optional in
      Documentation/devicetree/bindings/cpufreq/cpufreq-dt.txt and the usage
      in various device tree matches this, i.e., some cooling device in the
      device trees provide these properties while others do not.

      Make the bindings in
      Documentation/devicetree/bindings/thermal/thermal.txt consistent with
      the cpufreq-dt bindings by marking the cooling-*-level properties as
      optional.

      Docs: dt: add #msi-cells to GICv3 ITS binding

      The GICv3 ITS uses sideband master identification data (known as a
      DeviceID) to identify which master wrote to a doorbell, and this data is
      used to determine how to react in response to the write.

      Commit 1e6db000482fa65a ("irqchip/gicv3-its: Add platform MSI support")
      added support per this binding, but failed to update the documentation.
      This patch fixes the documentation.

      perf tools: Bool functions shouldn't return -1

      Returning a negative value for a boolean function seem to have the
      undesired effect of returning true. Replace -1 by false in a
      bool-returning function.

      The diff of the .s file before and after the change (for x86_64):

        3907c3907
        <       movl    $1, %ebx
        ---
        >       xorl    %ebx, %ebx

      while if -1 is replaced by true, the diff is empty.

      This issue was found by the following Coccinelle semantic patch:

        <smpl>
        @@
        identifier f;
        constant C;

      regulator: core: Correct return value check in regulator_resolve_supply

      The ret pointer passed to regulator_dev_lookup is only filled with a
      valid error code if regulator_dev_lookup returned NULL. Currently
      regulator_resolve_supply checks this ret value before it checks if a
      regulator was returned, this can result in valid regulator lookups being
      ignored.

      Revert "perf symbols: Fix mismatched declarations for elf_getphdrnum"

      This reverts commit f785f2357673d520a0b7b468973cdd197f336494.

      We have a test to check if elf_getphdrnum() is present, so, if it fails,
      we'll get:

        [acme@rhel5 linux]$ cat 
/tmp/build/perf/feature/test-libelf-getphdrnum.make.output
        cc1: warnings being treated as errors
        test-libelf-getphdrnum.c: In function â??mainâ??:
        test-libelf-getphdrnum.c:7: warning: implicit declaration of function 
â??elf_getphdrnumâ??
        [acme@rhel5 linux]$

      And this block will not be compiled:

        #ifndef HAVE_ELF_GETPHDRNUM_SUPPORT
        static int elf_getphdrnum(Elf *elf, size_t *dst)
        ...
        #endif

      So, if elf_getphdrnum() is being defined somewhere, there is a problem
      with the test that is not detecting that function, go fix it.

      block: fix bounce_end_io

      When bio bounce is involved, one new bio and its biovecs are
      cloned from the comming bio, which can be one fast-cloned bio
      from upper layer(such as dm).

      So it is obviously wrong to assume the start index of the coming(
      original) bio's io vector is zero, which can be any value between
      0 and (bi_max_vecs - 1), especially in case of bio split.

      This patch fixes Fedora's booting oops on i386, often with the
      following kernel log together:

      block: blk-merge: fast-clone bio when splitting rw bios

      biovecs has become immutable since v3.13, so it isn't necessary
      to allocate biovecs for the new cloned bios, then we can save
      one extra biovecs allocation/copy, and the allocation is often
      not fixed-length and a bit more expensive.

      For example, if the 'max_sectors_kb' of null blk's queue is set
      as 16(32 sectors) via sysfs just for making more splits, this patch
      can increase throught about ~70% in the sequential read test over
      null_blk(direct io, bs: 1M).

      This fixes a performance regression introduced by commit 54efd50bfd,

      pmem: add proper fencing to pmem_rw_page()

      libiscsi: Fix iscsi_check_transport_timeouts possible infinite loop

      Connection last_ping is not being updated when iscsi_send_nopout fails.
      Not updating the last_ping will cause firing a timer to a past time
      (last_ping + ping_tmo < current_time) which triggers an infinite loop of
      iscsi_check_transport_timeouts() and hogs the cpu.

      Fix this issue by checking the return value of iscsi_send_nopout.
      If it fails set the next_timeout to one second later.

      defined as the max allowed value because it need to
      meet all kinds of virtulization applications and
      need to support most of SoCs;

      2) using a bigger value doesn't introduce extra memory
      consumption, and the help text in Kconfig isn't accurate
      because kvm_vpu structure isn't allocated until request
      of creating VCPU is sent from QEMU;

      3) the main effect is that the field of vcpus[] in 'struct kvm'
      becomes a bit bigger(sizeof(void *) per vcpu) and need more cache
      lines to hold the structure, but 'struct kvm' is one generic struct,
      and it has worked well on other ARCHs already in this way. Also,
      the world switch frequecy is often low, for example, it is ~2000
      when running kernel building load in VM from APM xgene KVM host,
      so the effect is very small, and the difference can't be observed
      in my test at all.

      arm64: KVM: Remove all traces of the ThumbEE registers

      Although the ThumbEE registers and traps were present in earlier
      versions of the v8 architecture, it was retrospectively removed and so
      we can do the same.

      Whilst this breaks migrating a guest started on a previous version of
      the kernel, it is much better to kill these (non existent) registers
      as soon as possible.

      arm: KVM: Disable virtual timer even if the guest is not using it

      When running a guest with the architected timer disabled (with QEMU and
      the kernel_irqchip=off option, for example), it is important to make
      sure the timer gets turned off. Otherwise, the guest may try to

      The fix is to unconditionally turn off the virtual timer on guest

      s390/vtime: correct scaled cputime for SMT

      The scaled cputime is supposed to be derived from the normal per-thread
      cputime by dividing it with the average thread density in the last 
interval.

      The calculation of the scaling values for the average thread density is
      incorrect. The current, incorrect calculation:

          Ci = cycle count with i active threads
          T = unscaled cputime, sT = scaled cputime
          sT = T * (C1 + C2 + ... + Cn) / (1*C1 + 2*C2 + ... + n*Cn)

      The calculation happens to yield the correct numbers for the simple cases
      with only one Ci value not zero. But for cases with multiple Ci values not
      zero it fails. E.g. on a SMT-2 system with one thread active half the time
      and two threads active for the other half of the time it fails, the 
scaling
      factor should be 3/4 but the formula gives 2/3.

      The correct formula is

          sT = T * (C1/1 + C2/2 + ... + Cn/n) / (C1 + C2 + ... + Cn)

      Use ENOENT to indicate that particular counters are not available when the

      s390/compat: correct uc_sigmask of the compat signal frame

      The uc_sigmask in the ucontext structure is an array of words to keep
      the 64 signal bits (or 1024 if you ask glibc but the kernel sigset_t
      only has 64 bits).

      For 64 bit the sigset_t contains a single 8 byte word, but for 31 bit
      there are two 4 byte words. The compat signal handler code uses a
      simple copy of the 64 bit sigset_t to the 31 bit compat_sigset_t.
      As s390 is a big-endian architecture this is incorrect, the two words
      in the 31 bit sigset_t array need to be swapped.

      Bluetooth: Remove SCO fragments on connection close

      SCO packet reassembler may have a fragment of SCO packet, from
      previous connection, cached and not removed when SCO connection
      is ended. Packets from new SCO connection are then going to be
      attached to that fragment, creating an invalid SCO packets.

      Controllers like Intel's WilkinsPeak are always fragmenting
      SCO packet into 3 parts (#1, #2, #3). Packet #1 contains
      SCO header and audio data, others just audio data. if there is
      a fragment cached from previous connection, i.e. #1, first
      SCO packet from new connection is going to be attached to it
      creating packet consisting of fragments #1-#1-#2. This will
      be forwarded to upper layers. After that, fragment #3 is going
      to be used as a starting point for another SCO packet.
      It does not contain a SCO header, but the code expects it,
      casts a SCO header structure on it, and reads whatever audio
      data happens to be there as SCO packet length and handle.
      From that point on, we are assembling random data into SCO
      packets. Usually it recovers quickly as initial audio data
      contains mostly zeros (muted stream), but setups of over
      4 seconds were observed.
      Issue manifests itself by printing on the console:
      Bluetooth: hci0 SCO packet for unknown connection handle 48
      Bluetooth: hci0 SCO packet for unknown connection handle 2560
      Bluetooth: hci0 SCO packet for unknown connection handle 12288
      It may also show random handles if audio data was non-zeroed.
      Hcidump shows SCO packets with random length and handles.

      Few messages with handle 0 at connection creation are OK
      for some controllers (like WilkinsPeak), as there are SCO packets
      with zeroed handle at the beginning (possible controller bug).
      Few of such messages at connection end, with a handle looking
      sane (around 256, 512, 768 ...) is also OK, as these are last
      SCO packets that were assembled and sent up, before connection
      was ended, but were not handled in time.

      This issue may still manifest itself on WilkinsPeak as it sometimes,
      at SCO connection creation, does not send third fragment of first
      SCO packet (#1-#2-#1-#2-#3...). This is a firmware bug and this
      patch does not address it.

      at86rf230: interrupt tx with force trx_off

      To abort a TX_ARET_BUSY state it's recommended to switch into TRX_OFF
      state by doing STATE_TRX_FORCE_OFF. This patch will do always a TRX_OFF
      state change when the transceiver stucks in any state. From TRX_OFF we
      can switch to the states which are also possible by TX_ON state.

      at86rf230: change trac status check behaviour

      When transmit is done, indicated by trx_end irq, we do first a force
      state change to TX_ON and then checking the trac status, if the trac
      status is unequal zero we do a state change to TRX_OFF.

      This patch changes to the following behaviour, we first check on trac
      status after trx_end occurs and then doing a normal change to TX_ON
      without do the state change to TRX_OFF when trac status is unequal zero.

      The reasons are that the datasheet doesn't described when the trac
      status register is cleared, we should doing to evaluate the trac status
      at first. The reason to remove the TRX_OFF change if the trac status is
      unequal to zero and it was force is the following paragraph inside The
      at86rf2xx datasheets:

      "Using FORCE_PLL_ON to interrupt an TX_ARET transaction, it is
       recommended to check register bits [7:5] of register address 0x32 for
       value 0. If this value is different, TRX_CMD sequence FORCE_TRX_OFF shall
       be used immediately followed by TRX_CMD sequence PLL_ON. This performs a
       state transition to PLL_ON."

      The meaning is here "to interrupt an TX_ARET transaction" in case of
      trx_end interrupt the "TX_ARET transaction" is already done and we don't
      interrupt the "TX_ARET transaction" by doing the change to TX_ON (PLL_ON)
      here. Additional I changed the force change to normal TX_ON which seems to
      work here.

      ieee802154: 6lowpan: use correct ESC value for dispatch

      The ESC dispatch value has some history and it originally was 0x7f in 
rfc4944
      (see section-5.1). With the release of rfc6282 this value got part of the
      LOWPAN_IPHC range and was no longer available for ESC. Instead 0x40 was 
used
      as replacement (see section-2 in rfc6282).

      We have been checking the dispatch byte in an order where IPHC would 
always be
      evaluated before ESC and thus we would never reach the ESC check as the 
IPHC
      range already covers this value.

      Bluetooth: btmrvl: skb resource leak, and double free.

      if btmrvl_tx_pkt() is called, and the branch
        if (skb_headroom(skb) < BTM_HEADER_LEN)
      evaluates positive, a new skb is allocated via skb_realloc_headroom.

      The original skb is stored in a tmp variable, before being free'd.
      However on success, the new skb, is not free'd, nor is it
      returned to the caller which will then double-free the original skb.

      This issue exists from the original driver submission in
       commit: #132ff4e5fa8dfb71a7d99902f88043113947e972

      If this code path had been alive, it would have been noted from the
      double-free causing a panic.

      All skb's here should be allocated through bt_skb_alloc which
      adds 8 bytes as headroom, which is plenty against the 4 bytes
      pushed on by this driver.

      This code path is dead, and buggy at the same time, so the cleanest
      approach is to remove the affected branch.

      Bluetooth: hci_intel: Introduce LPM support

      Enable controller Low-Power-Mode if we have a pdev to manage host
      wake-up. Once LPM is enabled, controller notifies its TX status via
      a vendor specific packet (tx_idle/tx_active).
      tx_active means that there is more data upcoming from controller.
      tx_idle means that controller can be put in suspended state.

      arm64: errata: add module build workaround for erratum #843419

      Cortex-A53 processors <= r0p4 are affected by erratum #843419 which can
      lead to a memory access using an incorrect address in certain sequences
      headed by an ADRP instruction.

      There is a linker fix to generate veneers for ADRP instructions, but
      this doesn't work for kernel modules which are built as unlinked ELF
      objects.

      This patch adds a new config option for the erratum which, when enabled,
      builds kernel modules with the mcmodel=large flag. This uses absolute
      addressing for all kernel symbols, thereby removing the use of ADRP as
      a PC-relative form of addressing. The ADRP relocs are removed from the
      module loader so that we fail to load any potentially affected modules.

      arm64: compat: fix vfp save/restore across signal handlers in big-endian

      When saving/restoring the VFP registers from a compat (AArch32)
      signal frame, we rely on the compat registers forming a prefix of the
      native register file and therefore make use of copy_{to,from}_user to
      transfer between the native fpsimd_state and the compat_vfp_sigframe.

      Unfortunately, this doesn't work so well in a big-endian environment.
      Our fpsimd save/restore code operates directly on 128-bit quantities
      (Q registers) whereas the compat_vfp_sigframe represents the registers
      as an array of 64-bit (D) registers. The architecture packs the compat D
      registers into the Q registers, with the least significant bytes holding
      the lower register. Consequently, we need to swap the 64-bit halves when
      converting between these two representations on a big-endian machine.

      This patch replaces the __copy_{to,from}_user invocations in our
      compat VFP signal handling code with explicit __put_user loops that
      operate on 64-bit values and swap them accordingly.

      ath10k: implement mesh support

      Add support for mesh to ath10k.  We simply use an AP virtual interface
      in the firmware in order to enable beaconing without TSF adoption, and
      use the raw (802.11) transmit mode.

      Due to firmware limitations, the firmware must operate in raw
      (non-native 802.11) mode.  As this is configured at firmware init time,
      a new "rawmode" modparam is added, and mesh interfaces are available
      only if rawmode=true.  The firmware must advertise support for rawmode;
      tested successfully with firmware 10.2.4.70.6-2.

      When the module is loaded with (newly implemented) modparam rawmode=1, it
      will enable operating an open mesh STA via something like the following:

          ip link set wlan0 down
          iw dev wlan0 set type mp
          ip link set wlan0 up
          iw dev wlan0 set freq 5745 80 5775
          iw dev wlan0 mesh join mesh-vht

      leds:lp55xx: Correct Kconfig dependency for f/w user helper

      The commit [b67893206fc0: leds:lp55xx: fix firmware loading error]
      tries to address the firmware file handling with user helper, but it
      sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK.  Since the
      wrong option was enabled, the system got a regression -- it suffers
      from the unexpected long delays for non-present firmware files.

      This patch corrects the Kconfig dependency to the right one,
      CONFIG_FW_LOADER_USER_HELPER.  This doesn't change the fallback
      behavior but only enables UMH when needed.

      usb: fixes for v4.3-rc2

      First series of fixes for v4.3-rc cycle. The major points are
      a fix to a regression which would let gadget driver disable
      an endpoint that's already disabled and a fix to MUSB to make
      sure IRQs are masked when we're going to suspend and unmasked
      on resume.

      ARM: imx53: qsrb: fix PMIC interrupt level

      The MC34708 PMIC interrupt level is active high, but was set to
      active low in the devicetree, probably as a result of a copy and
      paste error from the QSB board.

      This caused IRQ storms and led to the kernel disabling the PMIC
      interrupt.

      powerpc32: memset: only use dcbz once cache is enabled

      memset() uses instruction dcbz to speed up clearing by not wasting time
      loading cache line with data that will be overwritten.
      Some platform like mpc52xx do no have cache active at startup and
      can therefore not use memset(). Allthough no part of the code
      explicitly uses memset(), GCC may make calls to it.

      This patch modifies memset() such that at startup, memset()
      unconditionally skip the optimised bloc that uses dcbz instruction.

      Once the initial MMU is set up, in machine_init() we patch memset()
      by replacing this inconditional jump by a NOP

      ARM: dts: am57xx-beagle-x15: Update Phy supplies

      Originally, all the SoC PHY rails were supplied by LDO3. However, as a
      result of characterization, it was determined that this posed a risk in
      extreme load  conditions. Hence the PHY rails are split between two
      different LDOs. Update the related node as a result

      LDO3/VDDA_1V8_PHYA supplies vdda_usb1, vdda_usb2, vdda_sata, vdda_usb3
      LDO4/VDDA_1V8_PHYB supplies vdda_pcie1, vdda_pcie0, vdda_hdmi, vdda_pcie

      NOTE: We break compatibility with pre-production boards with this change
      since, the PMIC LDO4 is disabled at OTP level.

      The new configuration is the plan of record and all pre-production
      boards are supposed to be replaced with the latest boards matching the
      mentioned configuration.

      Some very few 10 something boards have been created and
      stopped production till the latest modifications were done (PMIC USB
      interrupt, LDO4 etc) - and all of those boards are now getting
      scrapped.. If there are any (as per tracking information, there should
      not be any), TI should be contacted to have them replaced.

      ARM: 8425/1: kgdb: Don't try to stop the machine when setting breakpoints

      In (23a4e40 arm: kgdb: Handle read-only text / modules) we moved to
      using patch_text() to set breakpoints so that we could handle the case
      when we had CONFIG_DEBUG_RODATA.  That patch used patch_text().
      Unfortunately, patch_text() assumes that we're not in atomic context
      when it runs since it needs to grab a mutex and also wait for other
      CPUs to stop (which it does with a completion).

      This would result in a stack crawl if you had
      CONFIG_DEBUG_ATOMIC_SLEEP and tried to set a breakpoint in kgdb.  The
      crawl looked something like:

      It turns out that when we're in kgdb all the CPUs are stopped anyway
      so there's no reason we should be calling patch_text().  We can
      instead directly call __patch_text() which assumes that CPUs have
      already been stopped.

      clk: check for invalid parent index of orphans in __clk_init()

      If a mux clock is initialised (by hardware or firmware) with an
      invalid parent, its ->get_parent() can return an out of range
      index.  For example, the generic mux clock attempts to return
      -EINVAL, which due to the u8 return type ends up a rather large
      number.  Using this index with the parent_names[] array results
      in an invalid pointer and (usually) a crash in the following
      strcmp().

      This patch adds a check for the parent index being in range,
      ignoring clocks reporting invalid values.

      perf stat: Fix per-pkg event reporting bug

      Per-pkg events need to be captured once per processor socket. The code
      in check_per_pkg() ensures only one value per processor package is used.
      However there is a problem with this function in case the first CPU of
      the package does not measure anything for the per-pkg event, but other
      CPUs do.

      Consider the following:

        $ create cgroup FOO; echo $$ >FOO/tasks; taskset -c 1 noploop &
        $ perf stat -a -I 1000 -e intel_cqm/llc_occupancy/ -G FOO sleep 100
          1.00000 <not counted> Bytes intel_cqm/llc_occupancy/  FOO

      The reason for this is that CPU0 in the cgroup has nothing running on it.
      Yet check_per_plg() will mark socket0 as processed and no other event
      value will be considered for the socket.

      This patch fixes the problem by having check_per_pkg() only consider
      events which actually ran.

      ASoC: fix broken pxa SoC support

      The previous fix of pxa library support, which was introduced to fix the
      library dependency, broke the previous SoC behavior, where a machine
      code binding pxa2xx-ac97 with a coded relied on :
       - sound/soc/pxa/pxa2xx-ac97.c
       - sound/soc/codecs/XXX.c

      For example, the mioa701_wm9713.c machine code is currently broken. The
      "select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for
      compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared
      in sound/arm/Kconfig and sound/soc/pxa/Kconfig.

      Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct
      pxa2xx-ac97 compilation.

      arm/arm64: KVM: vgic: Check for !irqchip_in_kernel() when mapping 
resources

      Until b26e5fdac43c ("arm/arm64: KVM: introduce per-VM ops"),
      kvm_vgic_map_resources() used to include a check on irqchip_in_kernel(),
      and vgic_v2_map_resources() still has it.

      But now vm_ops are not initialized until we call kvm_vgic_create().
      Therefore kvm_vgic_map_resources() can being called without a VGIC,
      and we die because vm_ops.map_resources is NULL.

      Fixing this restores QEMU's kernel-irqchip=off option to a working state,
      allowing to use GIC emulation in userspace.

      per-process rwsem; unfortunately, the write [un]lock paths of

      The offending commit accidentally replaces an atomic_clear with an
      atomic_or instead of an atomic_andnot in kvm_s390_vcpu_request_handled.

       "This is the first round of GPIO fixes for v4.3.  Quite a lot of
        patches, but the influx of new stuff in the merge window was equally
        big, so I'm not surprised.

         - Return value checks and thus nicer errorpath for two drivers.

         - Make GPIO_RCAR arch neutral.

         - Propagate errors from GPIO chip ->get() vtable call.  It turned out
           these can actually fail sometimes, especially on slowpath
           controllers doing I2C traffic and similar.

         - Update documentation to be in sync with the massive changes in the
           v4.3 merge window, phew.

         - Handle deferred probe properly in the OMAP driver.

         - Get rid of surplus MODULE_ALIAS() from sx150x"

      sh: Kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      x86/platform: Fix Geode LX timekeeping in the generic x86 build

      In 2007, commit 07190a08eef36 ("Mark TSC on GeodeLX reliable")
      bypassed verification of the TSC on Geode LX. However, this code
      (now in the check_system_tsc_reliable() function in
      arch/x86/kernel/tsc.c) was only present if CONFIG_MGEODE_LX was
      set.

      OpenWRT has recently started building its generic Geode target
      for Geode GX, not LX, to include support for additional
      platforms. This broke the timekeeping on LX-based devices,
      because the TSC wasn't marked as reliable:
      https://dev.openwrt.org/ticket/20531

      By adding a runtime check on is_geode_lx(), we can also include
      the fix if CONFIG_MGEODEGX1 or CONFIG_X86_GENERIC are set, thus
      fixing the problem.

      arm: KVM: Fix incorrect device to IPA mapping

      A critical bug has been found in device memory stage1 translation for
      VMs with more then 4GB of address space. Once vm_pgoff size is smaller
      then pa (which is true for LPAE case, u32 and u64 respectively) some
      more significant bits of pa may be lost as a shift operation is performed
      on u32 and later cast onto u64.

      Example: vm_pgoff(u32)=0x00210030, PAGE_SHIFT=12
              expected pa(u64):   0x0000002010030000
              produced pa(u64):   0x0000000010030000

      The fix is to change the order of operations (casting first onto 
phys_addr_t
      and then shifting).

      KVM: vmx: fix VPID is 0000H in non-root operation

      Reference SDM 28.1:

      The current VPID is 0000H in the following situations:
      - Outside VMX operation. (This includes operation in system-management
        mode under the default treatment of SMIs and SMM with VMX operation;
        see Section 34.14.)
      - In VMX root operation.
      - In VMX non-root operation when the â??enable VPIDâ?? VM-execution 
control
        is 0.

      The VPID should never be 0000H in non-root operation when "enable VPID"
      VM-execution control is 1. However, commit 34a1cd60 ("kvm: x86: vmx:
      move some vmx setting from vmx_init() to hardware_setup()") remove the
      codes which reserve 0000H for VMX root operation.

      This patch fix it by again reserving 0000H for VMX root operation.

      powerpc/mm: Recompute hash value after a failed update

      If we had secondary hash flag set, we ended up modifying hash value in
      the updatepp code path. Hence with a failed updatepp we will be using
      a wrong hash value for the following hash insert. Fix this by
      recomputing hash before insert.

      Without this patch we can end up with using wrong slot number in linux
      pte. That can result in us missing an hash pte update or invalidate
      which can cause memory corruption or even machine check.

      KVM: add halt_attempted_poll to VCPU stats

      This new statistic can help diagnosing VCPUs that, for any reason,
      trigger bad behavior of halt_poll_ns autotuning.

      For example, say halt_poll_ns = 480000, and wakeups are spaced exactly
      like 479us, 481us, 479us, 481us. Then KVM always fails polling and wastes
      10+20+40+80+160+320+480 = 1110 microseconds out of every
      479+481+479+481+479+481+479 = 3359 microseconds. The VCPU then
      is consuming about 30% more CPU than it would use without
      polling.  This would show as an abnormally high number of
      attempted polling compared to the successful polls.

      ARM: fix Thumb2 signal handling when ARMv6 is enabled

      When a kernel is built covering ARMv6 to ARMv7, we omit to clear the
      IT state when entering a signal handler.  This can cause the first
      few instructions to be conditionally executed depending on the parent
      context.

      In any case, the original test for >= ARMv7 is broken - ARMv6 can have
      Thumb-2 support as well, and an ARMv6T2 specific build would omit this
      code too.

      Relax the test back to ARMv6 or greater.  This results in us always
      clearing the IT state bits in the PSR, even on CPUs where these bits
      are reserved.  However, they're reserved for the IT state, so this
      should cause no harm.

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      User visible changes:

      - Enhance the error reporting of tracepoint event parsing, e.g.:

          $ oldperf record -e sched:sched_switc usleep 1
          event syntax error: 'sched:sched_switc'
                               \___ unknown tracepoint
          Run 'perf list' for a list of valid events

        Now we get the much nicer:

          $ perf record -e sched:sched_switc ls
          event syntax error: 'sched:sched_switc'
                               \___ can't access trace events

          Error: No permissions to read 
/sys/kernel/debug/tracing/events/sched/sched_switc
          Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug'

        And after we have those mount point permissions fixed:

          $ perf record -e sched:sched_switc ls
          event syntax error: 'sched:sched_switc'
                               \___ unknown tracepoint

          Error: File /sys/kernel/debug/tracing/events/sched/sched_switc not 
found.
          Hint:  Perhaps this kernel misses some CONFIG_ setting to enable this 
feature?.

        Now its just a matter of using what git uses to suggest alternatives 
when we
        make a typo, i.e. that it is just an 'h' missing :-)

        I.e. basically now the event parsing routing uses the strerror_open()
        routines introduced by and used in 'perf trace' work. (Jiri Olsa)

      Infrastructure changes:

      - Export init/exit_probe_symbol_maps() from 'perf probe' for use in eBPF.
        (Namhyung Kim)

      - Free perf_probe_event in cleanup_perf_probe_events(). (Namhyung Kim)

      - regs_query_register_offset() infrastructure + implementation for x86.

      - Fix propagation of thread and cpu maps, that got broken when doing 
incomplete

PT to
        fail with an error like:

          Error: The sys_perf_event_open() syscall returned with

      dax: fix O_DIRECT I/O to the last block of a blockdev

      commit bbab37ddc20b (block: Add support for DAX reads/writes to
      block devices) caused a regression in mkfs.xfs.  That utility
      sets the block size of the device to the logical block size
      using the BLKBSZSET ioctl, and then issues a single sector read
      from the last sector of the device.  This results in the dax_io
      code trying to do a page-sized read from 512 bytes from the end
      of the device.  The result is -ERANGE being returned to userspace.

      The fix is to align the block to the page size before calling
      get_block.

      fm10k: fix iov_msg_mac_vlan_pf VID checks

      The VF will send a message to request multicast addresses with the
      default VID. In the current code, if the PF has statically assigned a
      VLAN to a VF, then the VF will not get the multicast addresses. Fix up
      all of the various VLAN messages to use identical checks (since each
      check was different). Also use set as a variable, so that it simplifies
      our check for whether VLAN matches the pf_vid.

      The new logic will allow set of a VLAN if it is zero, automatically
      converting to the default VID. Otherwise it will allow setting the PF
      VID, or any VLAN if PF has not statically assigned a VLAN. This is
      consistent behavior, and allows VF to request either 0 or the
      default_vid without silently failing.

      Note that we need the check for zero since VFs might not get the default
      VID message in time to actually request non-zero VLANs.

      fm10k: Only trigger data path reset if fabric is up

      This change makes it so that we only trigger the data path reset if the
      fabric is ready to handle traffic.  The general idea is to avoid
      triggering the reset unless the switch API is ready for us.  Otherwise
      we can just postpone the reset until we receive a switch ready
      notification.

      fm10k: re-enable VF after a full reset on detection of a Malicious event

      Modify behavior of Malicious Driver Detection events. Presently, the
      hardware disables the VF queues and re-assigns them to the PF. This
      causes the VF in question to continuously Tx hang, because it assumes
      that it can transmit over the queues in question. For transient events,
      this results in continuous logging of malicious events.

      New behavior is to reset the LPORT and VF state, so that the VF will
      have to reset and re-enable itself. This does mean that malicious VFs
      will possibly be able to continue and attempt malicious events again.
      However, it is expected that system administrators will step in and
      manually remove or disable the VF in question.

      fm10k: send traffic on default VID to VLAN device if we have one

      This patch ensures that VLAN traffic on the default VID will go to the
      corresponding VLAN device if it exists. To do this, mask the rx_ring VID
      if we have an active VLAN on that VID.

      For this to work correctly, we need to update fm10k_process_skb_fields
      to correctly mask off the VLAN_PRIO_MASK bits and compare them
      separately, otherwise we incorrectly compare the priority bits with the
      cleared flag. This also happens to fix a related bug where having
      priority bits set causes us to incorrectly classify traffic.

      ixgbe: Limit lowest interrupt rate for adaptive interrupt moderation to 
12K

      This patch updates the lowest limit for adaptive interrupt interrupt
      moderation to roughly 12K interrupts per second.

      The way I came about reaching 12K as the desired interrupt rate is by
      testing with UDP flows.  Specifically I had a simple test that ran a
      netperf UDP_STREAM test at varying sizes.  What I found was as the packet
      sizes increased the performance fell steadily behind until we were only
      able to receive at ~4Gb/s with a message size of 65507.  A bit of digging
      found that we were dropping packets for the socket in the network stack,
      and looking at things further what I found was I could solve it by 
increasing
      the interrupt rate, or increasing the rmem_default/rmem_max.  What I 
found was
      that when the interrupt coalescing resulted in more data being processed
      per interrupt than could be stored in the socket buffer we started losing
      packets and the performance dropped.  So I reached 12K based on the
      following math.

      rmem_default = 212992
      skb->truesize = 2994
      212992 / 2994 = 71.14 packets to fill the buffer

      packet rate at 1514 packet size is 812744pps
      71.14 / 812744 = 87.9us to fill socket buffer

      From there it was just a matter of choosing the interrupt rate and
      providing a bit of wiggle room which is why I decided to go with 12K
      interrupts per second as that uses a value of 84us.

      The data below is based on VM to VM over a direct assigned ixgbe 
interface.
      The test run was:
        netperf -H <ip> -t UDP_STREAM"

      Socket  Message  Elapsed      Messages                   CPU      Service

      ixgbe: Teardown SR-IOV before unregister_netdev()

      When the .remove() callback for a PF is called, SR-IOV support for the
      device is disabled, which requires unbinding and removing the VFs.
      The VFs may be in-use either by the host kernel or userspace, such as
      assigned to a VM through vfio-pci.  In this latter case, the VFs may
      be removed either by shutting down the VM or hot-unplugging the
      devices from the VM.  Unfortunately in the case of a Windows 2012 R2
      guest, hot-unplug is broken due to the ordering of the PF driver
      teardown.  Disabling SR-IOV prior to unregister_netdev() avoids this
      issue.

      openvswitch: Fix mask generation for nested attributes.

      Masks were added to OVS flows in a way that was backwards compatible
      with userspace programs that did not generate masks. As a result, it is
      possible that we may receive flows that do not have a mask and we need
      to synthesize one.

      Generating a mask requires iterating over attributes and descending into
      nested attributes. For each level we need to know the size to generate the
      correct mask. We do this with a linked table of attribute types.

      Although the logic to handle these nested attributes was there in concept,
      there are a number of bugs in practice. Examples include incomplete links
      between tables, variable length attributes being treated as nested and
      missing sanity checks.

      iser-target: Skip data copy if all the command data comes as immediate

      Given that supporting zcopy immediate data for all IOs requires

      avoiding data copy for IOs with data length of up to 8K (which
      is more latency sensitive anyway).

      This trims IO write latency by up to 3us and increase IOPs
      by up to 40% by saving CPU time doing sg_copy_from_buffer
      (8K IO size is the obvious winner here).

      iser-target: Change the recv buffers posting logic

      iser target batches post recv operations to avoid
      the overhead of acquiring the recv queue lock and
      posting a HW doorbell for each command.

      We change it to be per command in order to support
      zcopy immediate data for IOs that fits in the 8K
      transfer boundary (in the next patch).

      iser-target: Fix pending connections handling in target stack shutdown 
sequnce

      Instead of handing a connection to the iscsi stack
      for processing right after accepting (rdma_accept) we only hand
      the connection to the iscsi core after we reached to a connected
      state (ESTABLISHED CM event). This will prevent two error scenrios:

      1. race between rdma connection teardown and iscsi login sequence
         reported by Nic in: (ce9a9fc20a78a "iser-target: Fix REJECT CM event
         use-after-free OOPs")

      2. target stack shutdown sequence race with constant login attempts by
         multiple initiators.

      We address this by maintaining two queues at the isert_np level:
      - accepted: connections that were accepted but have not reached
        connected state (might get rejected, unreachable or error).
      - pending: connections in connected state, but have yet to handed
        to the iscsi core for login processing. iser connections are promoted
        to the pending queue only from the accepted queue.

      This way the iscsi core now will only handle functional iser connections
      and once we shutdown the target stack, we look for any stales that
      got left behind so we can safely release them.

      iser-target: Put the reference on commands waiting for unsol data

      The iscsi target core teardown sequence calls wait_conn for
      all active commands to finish gracefully by:
      - move the queue-pair to error state
      - drain all the completions
      - wait for the core to finish handling all session commands

      However, when tearing down a session while there are sequenced
      commands that are still waiting for unsolicited data outs, we can
      block forever as these are missing an extra reference put.

      We basically need the equivalent of iscsit_free_queue_reqs_for_conn()
      which is called after wait_conn has returned. Address this by an
      explicit walk on conn_cmd_list and put the extra reference.

      iser-target: remove command with state ISTATE_REMOVE

      As documented in iscsit_sequence_cmd:
      /*
       * Existing callers for iscsit_sequence_cmd() will silently
       * ignore commands with CMDSN_LOWER_THAN_EXP, so force this
       * return for CMDSN_MAXCMDSN_OVERRUN as well..
       */

      We need to silently finish a command when it's in ISTATE_REMOVE.
      This fixes an teardown hang we were seeing where a mis-behaved
      initiator (triggered by allocation error injections) sent us a
      cmdsn which was lower than expected.

      rtnetlink: RTEXT_FILTER_SKIP_STATS support to avoid dumping inet/inet6 
stats

      Many commonly used functions like getifaddrs() invoke RTM_GETLINK
      to dump the interface information, and do not need the
      the AF_INET6 statististics that are always returned by default
      from rtnl_fill_ifinfo().

      Computing the statistics can be an expensive operation that impacts
      scaling, so it is desirable to avoid this if the information is
      not needed.

      This patch adds a the RTEXT_FILTER_SKIP_STATS extended info flag that
      can be passed with netlink_request() to avoid statistics computation
      for the ifinfo path.

      net: stmmac: Use msleep rather then udelay for reset delay

      The reset delays used for stmmac are in the order of 10ms to 1 second,
      which is far too long for udelay usage, so switch to using msleep.

      Practically this fixes the PHY not being reliably detected in some cases
      as udelay wouldn't actually delay for long enough to let the phy
      reliably be reset.

      This patch fixes a regression introduced by the commit a84e32894191
      ("net: mvneta: fix refilling for Rx DMA buffers"). Due to this commit
      the newly allocated Rx buffers are DMA-unmapped in place of those passed
      to the networking stack. Obviously, this causes data corruptions.

      This patch fixes the issue by ensuring that the right Rx buffers are
      DMA-unmapped.

        re-test it

      v3:
      - Merge a 'if else if' test in patch 4
      - Use rcu_dereference_protected in patch 5 to fix a sparse check when
        CONFIG_SPARSE_RCU_POINTER is enabled

      v2:
      - Add patch 4 and 5 to remove the spinlock

      v1:
      This patch series is to fix the dst refcnt bugs in ip6_tunnel.

      Patch 1 and 2 are the prep works.  Patch 3 is the fix.

      I can reproduce the bug by adding and removing the ip6gre tunnel
      while running a super_netperf TCP_CRR test.  I get the following
      trace by adding WARN_ON_ONCE(newrefcnt < 0) to dst_release():

      ipv6: Avoid double dst_free

      It is a prep work to get dst freeing from fib tree undergo
      a rcu grace period.

      The following is a common paradigm:
      if (ip6_del_rt(rt))
        dst_free(rt)

      which means, if rt cannot be deleted from the fib tree, dst_free(rt) now.
      1. We don't know the ip6_del_rt(rt) failure is because it
         was not managed by fib tree (e.g. DST_NOCACHE) or it had already been
         removed from the fib tree.
      2. If rt had been managed by the fib tree, ip6_del_rt(rt) failure means
         dst_free(rt) has been called already.  A second
         dst_free(rt) is not always obviously safe.  The rt may have
         been destroyed already.
      3. If rt is a DST_NOCACHE, dst_free(rt) should not be called.
      4. It is a stopper to make dst freeing from fib tree undergo a
         rcu grace period.

      This patch is to use a DST_NOCACHE flag to indicate a rt is
      not managed by the fib tree.

      ipv6: Fix dst_entry refcnt bugs in ip6_tunnel

      Problems in the current dst_entry cache in the ip6_tunnel:

      1. ip6_tnl_dst_set is racy.  There is no lock to protect it:
         - One major problem is that the dst refcnt gets messed up. F.e.
           the same dst_cache can be released multiple times and then
           triggering the infamous dst refcnt < 0 warning message.
         - Another issue is the inconsistency between dst_cache and
           dst_cookie.

         It can be reproduced by adding and removing the ip6gre tunnel
         while running a super_netperf TCP_CRR test.

      2. ip6_tnl_dst_get does not take the dst refcnt before returning
         the dst.

      This patch:
      1. Create a percpu dst_entry cache in ip6_tnl
      2. Use a spinlock to protect the dst_cache operations
      3. ip6_tnl_dst_get always takes the dst refcnt before returning

         reflect that it will take a dst refcnt in the next patch.
      2. ip6_tnl_dst_store() to ip6_tnl_dst_set() to have a more
         conventional name matching with ip6_tnl_dst_get().

      drivers: net: cpsw: Add support to drive gpios for ethernet to be 
functional

      In DRA72x EVM, by default slave 1 is connected to the onboard
      phy, but slave 2 pins are also muxed with video input module
      which is controlled by pcf857x gpio and currently to select slave
      0 to connect to phy gpio hogging is used, but with
      omap2plus_defconfig the pcf857x gpio is built as module. So when
      using NFS on DRA72x EVM, board doesn't boot as gpio hogging do
      not set proper gpio state to connect slave 0 to phy as it is
      built as module and you do not see any errors for not setting
      gpio and just mentions dhcp reply not got.

      To solve this issue, introducing "mode-gpios" in DT when gpio
      based muxing is required. This will throw a warning when gpio
      get fails and returns probe defer. When gpio-pcf857x module is
      installed, cpsw probes again and ethernet becomes functional.
      Verified this on DRA72x with pcf as module and ramdisk.

      These Marvell switches have 4 operations to flush or (re)move, all or

      PCI: Revert "PCI: Call pci_read_bridge_bases() from core instead of arch 
code"

      Revert dff22d2054b5 ("PCI: Call pci_read_bridge_bases() from core instead
      of arch code").

      Reading PCI bridge windows is not arch-specific in itself, but there is 
PCI
      core code that doesn't work correctly if we read them too early.  For
      example, Hannes found this case on an ARM Freescale i.mx6 board:

        pci_bus 0000:00: root bus resource [mem 0x01000000-0x01efffff]
        pci 0000:00:00.0: PCI bridge to [bus 01-ff]
        pci 0000:00:00.0: BAR 8: no space for [mem size 0x01000000] (mem window)
        pci 0000:01:00.0: BAR 2: failed to assign [mem size 0x00200000]
        pci 0000:01:00.0: BAR 1: failed to assign [mem size 0x00004000]
        pci 0000:01:00.0: BAR 0: failed to assign [mem size 0x00000100]

      The 00:00.0 mem window needs to be at least 3MB: the 01:00.0 device needs
      0x204100 of space, and mem windows are megabyte-aligned.

      Bus sizing can increase a bridge window size, but never *decrease* it (see
      d65245c3297a ("PCI: don't shrink bridge resources")).  Prior to
      dff22d2054b5, ARM didn't read bridge windows at all, so the "original 
size"
      was zero, and we assigned a 3MB window.

      After dff22d2054b5, we read the bridge windows before sizing the bus.  The
      firmware programmed a 16MB window (size 0x01000000) in 00:00.0, and since
      we never decrease the size, we kept 16MB even though we only needed 3MB.
      But 16MB doesn't fit in the host bridge aperture, so we failed to assign
      space for the window and the downstream devices.

      I think this is a defect in the PCI core: we shouldn't rely on the 
firmware
      to assign sensible windows.

      Ray reported a similar problem, also on ARM, with Broadcom iProc.

      Issues like this are too hard to fix right now, so revert dff22d2054b5.

      irqchip/renesas-irqc: Propagate wake-up settings to parent

      The renesas-irqc interrupt controller is cascaded to the GIC, but its
      driver doesn't propagate wake-up settings to the parent interrupt
      controller.

      Since commit aec89ef72ba6c944 ("irqchip/gic: Enable SKIP_SET_WAKE and
      MASK_ON_SUSPEND"), the GIC driver masks interrupts during suspend, and
      wake-up through gpio-keys now fails on r8a73a4/ape6evm.

      irqchip/renesas-intc-irqpin: Propagate wake-up settings to parent

      The renesas-intc-irqpin interrupt controller is cascaded to the GIC, but
      its driver doesn't propagate wake-up settings to the parent interrupt
      controller.

      Since commit aec89ef72ba6c944 ("irqchip/gic: Enable SKIP_SET_WAKE and
      MASK_ON_SUSPEND"), the GIC driver masks interrupts during suspend, and
      wake-up through gpio-keys now fails on r8a7740/armadillo and
      sh73a0/kzm9g.

      Fix this by propagating wake-up settings to the parent interrupt
      controller. There's no need to handle irq_set_irq_wake() failures, as
      the renesas-intc-irqpin interrupt controller is always cascaded to a
      GIC, and the GIC driver always sets SKIP_SET_WAKE since the
      aforementioned commit.

      When the ITS is configured for non-cacheable transactions, make sure
      that the allocated, zeroed memory is flushed to the Point of
      Coherency, allowing the ITS to observe the zeros instead of random
      garbage (or even get its own data overwritten by zeros being evicted
      from the cache...).

      irqchip/GIC: Add workaround for aliased GIC400

      The GICv2 architecture mandates that the two 4kB GIC regions are
      contiguous, and on two separate physical pages (so that access to
      the second page can be trapped by a hypervisor). This doesn't work
      very well when PAGE_SIZE is 64kB.

      A relatively common hack^Wway to work around this is to alias each
      4kB region over its own 64kB page. Of course in this case, the base
      address you want to use is not really the begining of the region,
      but base + 60kB (so that you get a contiguous 8kB region over two
      distinct pages).

      Normally, this would be described in DT with a new property, but
      some HW is already out there, and the firmware makes sure that
      it will override whatever you put in the GIC node. Duh. And of course,
      said firmware source code is not available, despite being based
      on u-boot.

      The workaround is to detect the case where the CPU interface size
      is set to 128kB, and verify the aliasing by checking that the ID
      register for GIC400 (which is the only GIC wired this way so far)
      is the same at base and base + 0xF000. In this case, we update
      the GIC base address and let it roll.

      And if you feel slightly sick by looking at this, rest assured that
      I do too...

      platform-msi: Do not cache msi_desc in handler_data

      The current implementation of platform MSI caches the msi_desc
      pointer in irq_data::handler_data. This is a bit silly, as
      we also have irq_data::msi_desc, which is perfectly valid.

      Remove the useless assignment and simplify the whole flow.

      kvm: fix zero length mmio searching

      Currently, if we had a zero length mmio eventfd assigned on
      KVM_MMIO_BUS. It will never be found by kvm_io_bus_cmp() since it
      always compares the kvm_io_range() with the length that guest
      wrote. This will cause e.g for vhost, kick will be trapped by qemu
      userspace instead of vhost. Fixing this by using zero length if an
      iodevice is zero length.

      kvm: fix double free for fast mmio eventfd

      We register wildcard mmio eventfd on two buses, once for KVM_MMIO_BUS
      and once on KVM_FAST_MMIO_BUS but with a single iodev
      instance. This will lead to an issue: kvm_io_bus_destroy() knows
      nothing about the devices on two buses pointing to a single dev. Which
      will lead to double free[1] during exit. Fix this by allocating two
      instances of iodevs then registering one on KVM_MMIO_BUS and another
      on KVM_FAST_MMIO_BUS.

      arm64: head.S: initialise mdcr_el2 in el2_setup

      When entering the kernel at EL2, we fail to initialise the MDCR_EL2
      register which controls debug access and PMU capabilities at EL1.

      This patch ensures that the register is initialised so that all traps
      are disabled and all the PMU counters are available to the host. When a
      guest is scheduled, KVM takes care to configure trapping appropriately.

      perf_evlist__propagate_maps() incorrectly assumes evsel->threads is NULL

      is used to set different (or NULL) maps.  Thus thread_map__put must be

      This illustrates that it is better if perf_evlist__splice_list_tail()
      calls perf_evlist__add() instead of duplicating the logic, so do that.
      This will also simplify a subsequent fix for propagating maps.

      perf evlist: Remove redundant validation from propagate_maps()

      The validation checks that the values that were just assigned, got
      assigned i.e. the error can't ever happen.  Subsequent patches will call
      this code in places where errors are not being returned.  Changing those
      code paths to return this non-existent error is counter-productive, so
      just remove it.

      That in turn results in perf_evlist__set_maps not needing to return an
      error, but callers aren't checking it either, so remove that too.

      perf tools: Introduce regs_query_register_offset() for x86

      regs_query_register_offset() is a helper function which converts
      register name like "%rax" to offset of a register in 'struct pt_regs',
      which is required by BPF prologue generator. Since the function is
      identical, try to reuse the code in arch/x86/kernel/ptrace.c.

      Comment inside dwarf-regs.c list the differences between this
      implementation and kernel code.

      get_arch_regstr() switches to regoffset_table and the old string table
      is dropped.

      perf tools: regs_query_register_offset() infrastructure

      regs_query_register_offset() is a helper function which converts
      register name like "%rax" to offset of a register in 'struct pt_regs',
      which is required by BPF prologue generator.

      PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET indicates an architecture
      supports converting name of a register to its offset in 'struct
      pt_regs'.

      HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET is introduced as the corresponding
      CFLAGS of PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET.

      cxl: Fix build failure due to -Wunused-variable behaviour change

      A recent change in gcc caused this build failure:

      
/var/lib/jenkins/workspace/gcc_kernel_build/linux/drivers/misc/cxl/cxl.h:72:27:
      error: â??CXL_PSL_DLCNTLâ?? defined but not used 
[-Werror=unused-const-variable]
       static const cxl_p1_reg_t CXL_PSL_DLCNTL  = {0x0060};

      Because of this gcc commit:

      Commit 1bca8cbd0c68366f07277f98ce6963e10c2aa617 by mark
      PR28901 -Wunused-variable ignores unused const initialised variables in C
      12 years ago it was decided that -Wunused-variable shouldn't warn about
      static const variables because some code used const static char rcsid[]
      strings which were never used but wanted in the code anyway. But as the
      bug points out this hides some real bugs. These days the usage of
      rcsids is not very popular anymore. So this patch changes the default
      to warn about unused static const variables in C with
      -Wunused-variable. And it adds a new option -Wno-unused-const-variable
      to turn this warning off. For C++ this new warning is off by default,
      since const variables can be used as #defines in C++. New testcases for
      the new defaults in C and C++ are included testing the new warning and
      suppressing it with an unused attribute or using
      -Wno-unused-const-variable. gcc/ChangeLog

      The cxl driver uses static consts in place of #defines in some cases
      for type safety, so this change causes the driver to fail to build on
      new copilers as these constants are not all used in every file that
      imports the header. Suppress the warning for this driver to return to
      the old behaviour of -Wunused-variable.

      cxl: Fix unbalanced pci_dev_get in cxl_probe

      Currently the first thing we do in cxl_probe is to grab a reference
      on the pci device. Later on, we call device_register on our adapter.
      In our remove path, we call device_unregister, but we never call
      pci_dev_put. We therefore leak the device every time we do a
      reflash.

      device_register/unregister is sufficient to hold the reference.
      Therefore, drop the call to pci_dev_get.

      Here's why this is safe.
      The proposed cxl_probe(pdev) calls cxl_adapter_init:
          a) init calls cxl_adapter_alloc, which creates a struct cxl,
             conventionally called adapter. This struct contains a
             device entry, adapter->dev.

          b) init calls cxl_configure_adapter, where we set
             adapter->dev.parent = &dev->dev (here dev is the pci dev)

      So at this point, the cxl adapter's device's parent is the PCI
      device that I want to be refcounted properly.

          c) init calls cxl_register_adapter
             *) cxl_register_adapter calls device_register(&adapter->dev)

      So now we're in device_register, where dev is the adapter device, and
      we want to know if the PCI device is safe after we return.

      device_register(&adapter->dev) calls device_initialize() and then
      device_add().

      device_add() does a get_device(). device_add() also explicitly grabs
      the device's parent, and calls get_device() on it:

               parent = get_device(dev->parent);

      So therefore, device_register() takes a lock on the parent PCI dev,
      which is what pci_dev_get() was guarding. pci_dev_get() can therefore
      be safely removed.

      usb: chipidea: udc: using the correct stall implementation

      According to spec, there are functional and protocol stalls.

      For functional stall, it is for bulk and interrupt endpoints,
      below are cases for it:
      - Host sends SET_FEATURE request for Set-Halt, the udc driver
      needs to set stall, and return true unconditionally.
      - The gadget driver may call usb_ep_set_halt to stall certain
      endpoints, if there is a transfer in pending, the udc driver
      should not set stall, and return -EAGAIN accordingly.
      These two kinds of stall need to be cleared by host using CLEAR_FEATURE
      request (Clear-Halt).

      For protocol stall, it is for control endpoint, this stall will
      be set if the control request has failed. This stall will be
      cleared by next setup request (hardware will do it).

      It fixed usbtest (drivers/usb/misc/usbtest.c) Test 13 "set/clear halt"
      test failure, meanwhile, this change has been verified by
      USB2 CV Compliance Test and MSC Tests.

      drm/ttm: Fix memory space allocation v2

      In the event that TTM doesn't find a compatible memory type for the

      returns -EINVAL without trying the driver's second choice.
      This causes problems on vmwgfx when VRAM is disabled before first modeset
      and during VT switches when fbdev is not enabled.

      Fix this by also trying the driver's second choice before returning
      -EINVAL.

      btrfs: skip waiting on ordered range for special files

      In btrfs_evict_inode, we properly truncate the page cache for evicted
      inodes but then we call btrfs_wait_ordered_range for every inode as well.
      It's the right thing to do for regular files but results in incorrect
      behavior for device inodes for block devices.

      filemap_fdatawrite_range gets called with inode->i_mapping which gets
      resolved to the block device inode before getting passed to
      wbc_attach_fdatawrite_inode and ultimately to inode_to_bdi.  What happens
      next depends on whether there's an open file handle associated with the
      inode.  If there is, we write to the block device, which is unexpected
      behavior.  If there isn't, we through normally and inode->i_data is used.
      We can also end up racing against open/close which can result in crashes
      when i_mapping points to a block device inode that has been closed.

      Since there can't be any page cache associated with special file inodes,
      it's safe to skip the btrfs_wait_ordered_range call entirely and avoid

      Btrfs: fix read corruption of compressed and shared extents

      If a file has a range pointing to a compressed extent, followed by
      another range that points to the same compressed extent and a read
      operation attempts to read both ranges (either completely or part of
      them), the pages that correspond to the second range are incorrectly
      filled with zeroes.

      Consider the following example:

        File layout
        [0 - 8K]                      [8K - 24K]
            |                             |
            |                             |
         points to extent X,         points to extent X,
         offset 4K, length of 8K     offset 0, length 16K

        [extent X, compressed length = 4K uncompressed length = 16K]

      If a readpages() call spans the 2 ranges, a single bio to read the extent
      is submitted - extent_io.c:submit_extent_page() would only create a new
      bio to cover the second range pointing to the extent if the extent it
      points to had a different logical address than the extent associated with
      the first range. This has a consequence of the compressed read end io
      handler (compression.c:end_compressed_bio_read()) finish once the extent
      is decompressed into the pages covering the first range, leaving the
      remaining pages (belonging to the second range) filled with zeroes (done
      by compression.c:btrfs_clear_biovec_end()).

      So fix this by submitting the current bio whenever we find a range
      pointing to a compressed extent that was preceded by a range with a
      different extent map. This is the simplest solution for this corner
      case. Making the end io callback populate both ranges (or more, if we
      have multiple pointing to the same extent) is a much more complex
      solution since each bio is tightly coupled with a single extent map and
      the extent maps associated to the ranges pointing to the shared extent
      can have different offsets and lengths.

      The following test case for fstests triggers the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$
        status=1        # failure is the default!
        trap "_cleanup; exit \$status" 0 1 2 3 15

        _cleanup()
        {
            rm -f $tmp.*
        }

      Looks like I made a typo on the control base, all the 81xx

      In addition to fixing the contol base, we need to also use the

      x86/apic: Serialize LVTT and TSC_DEADLINE writes

      The APIC LVTT register is MMIO mapped but the TSC_DEADLINE register is an
      MSR. The write to the TSC_DEADLINE MSR is not serializing, so it's not
      guaranteed that the write to LVTT has reached the APIC before the
      TSC_DEADLINE MSR is written. In such a case the write to the MSR is
      ignored and as a consequence the local timer interrupt never fires.

      The SDM decribes this issue for xAPIC and x2APIC modes. The
      serialization methods recommended by the SDM differ.

      xAPIC:
       "1. Memory-mapped write to LVT Timer Register, setting bits 18:17 to 10b.
        2. WRMSR to the IA32_TSC_DEADLINE MSR a value much larger than current 
time-stamp counter.
        3. If RDMSR of the IA32_TSC_DEADLINE MSR returns zero, go to step 2.
        4. WRMSR to the IA32_TSC_DEADLINE MSR the desired deadline."

      x2APIC:
       "To allow for efficient access to the APIC registers in x2APIC mode,
        the serializing semantics of WRMSR are relaxed when writing to the
        APIC registers. Thus, system software should not use 'WRMSR to APIC
        registers in x2APIC mode' as a serializing instruction. Read and write
        accesses to the APIC registers will occur in program order. A WRMSR to
        an APIC register may complete before all preceding stores are globally
        visible; software can prevent this by inserting a serializing
        instruction, an SFENCE, or an MFENCE before the WRMSR."

      The xAPIC method is to just wait for the memory mapped write to hit
      the LVTT by checking whether the MSR write has reached the hardware.
      There is no reason why a proper MFENCE after the memory mapped write would
      not do the same. Andi Kleen confirmed that MFENCE is sufficient for the
      xAPIC case as well.

      Issue MFENCE before writing to the TSC_DEADLINE MSR. This can be done
      unconditionally as all CPUs which have TSC_DEADLINE also have MFENCE
      support.

      x86/ioapic: Force affinity setting in setup_ioapic_dest()

      The recent ioapic cleanups changed the affinity setting in
      setup_ioapic_dest() from a direct write to the hardware to the delayed
      affinity setup via irq_set_affinity().

      That results in a warning from chained_irq_exit():
      WARNING: CPU: 0 PID: 5 at kernel/irq/migration.c:32 irq_move_masked_irq
      [<ffffffff810a0a88>] irq_move_masked_irq+0xb8/0xc0
      [<ffffffff8103c161>] ioapic_ack_level+0x111/0x130
      [<ffffffff812bbfe8>] intel_gpio_irq_handler+0x148/0x1c0

      The reason is that irq_set_affinity() does not write directly to the
      hardware. It marks the affinity setting as pending and executes it
      from the next interrupt. The chained handler infrastructure does not
      take the irq descriptor lock for performance reasons because such a
      chained interrupt is not visible to any interfaces. So the delayed
      affinity setting triggers the warning in irq_move_masked_irq().

      Restore the old behaviour by calling the set_affinity function of the
      ioapic chip in setup_ioapic_dest(). This is safe as none of the
      interrupts can be on the fly at this point.

      dm crypt: constrain crypt device's max_segment_size to PAGE_SIZE

      Setting the dm-crypt device's max_segment_size to PAGE_SIZE is an
      unfortunate constraint that is required to avoid the potential for
      exceeding dm-crypt's underlying device's max_segments limits -- due to
      crypt_alloc_buffer() possibly allocating pages for the encryption bio
      that are not as physically contiguous as the original bio.

      It is interesting to note that this problem was already fixed back in
      2007 via commit 91e106259 ("dm crypt: use bio_add_page").  But Linux 4.0
      commit cf2f1abfb ("dm crypt: don't allocate pages for a partial
      request") regressed dm-crypt back to _not_ using bio_add_page().  But
      given dm-crypt's cpu parallelization changes all depend on commit
      cf2f1abfb's abandoning of the more complex io fragments processing that
      dm-crypt previously had we cannot easily go back to using
      bio_add_page().

      So all said the cleanest way to resolve this issue is to fix dm-crypt to
      properly constrain the original bios entering dm-crypt so the encryption
      bios that dm-crypt generates from the original bios are always
      compatible with the underlying device's max_segments queue limits.

      It should be noted that technically Linux 4.3 does _not_ need this fix
      because of the block core's new late bio-splitting capability.  But, it
      is reasoned, there is little to be gained by having the block core split
      the encrypted bio that is composed of PAGE_SIZE segments.  That said, in
      the future we may revert this change.

      perf machine: Add pointer to sample's environment

      The 'struct machine' represents the machine where the samples were/are
      being collected, and we also have a 'struct perf_env' with extra details
      about such machine, that we were collecting at 'perf.data' creation time
      but we also needed when no perf.data file is being used, such as in
      'perf top'.

      So, get those structs closer together, as they provide a bigger picture
      of the sample's environment.

      In 'perf session', when the file argument is NULL, we can assume that
      the tool is sampling the running machine, so point machine->env to
      the global put in place in previous patches, while set it to the
      perf_header.env one when reading from a file.

      This paves the way for machine->env to be used in
      perf_event__preprocess_sample to populate addr_location.socket.

      perf env: Introduce read_cpu_topology_map() method

      Out of the code to write the cpu topology map in the perf.data file
      header.

      Now if one needs the CPU topology map for the running machine, one needs
      to call perf_env__read_cpu_topology_map(perf_env) and the info will be
      stored in perf_env.cpu.

      For now we're using a global perf_env variable, that will have its
      contents freed after we run a builtin.

      E.g.:

       $ ./cpu__get_max_freq
       3200000

      It does that, as Kan's patch does, by looking at these files:

        $ cat /sys/devices/system/cpu/online
        0-3
        $ ./sysfs__read_ull

        $

      I.e. find out the first online CPU, then read its cpufreq info.

      But do it in tools/lib/api/, so that other tools/ living code can use
      it, not just perf.

      Since it can be used separately from 'perf_session' and 'perf_header',

      perf tests: Introduce iterator function for tests

      In preparation for introducing more arrays of tests, e.g. "arch tests"
      (architecture-specific tests), abstract the code to iterate over the
      list of tests into a helper function.

      This way, code that uses a 'struct test' doesn't need to worry about how
      the tests are grouped together and changes to the list of tests doesn't
      require changes to the code using it.

      KVM: arm64: add workaround for Cortex-A57 erratum #852523

      When restoring the system register state for an AArch32 guest at EL2,
      writes to DACR32_EL2 may not be correctly synchronised by Cortex-A57,
      which can lead to the guest effectively running with junk in the DACR
      and running into unexpected domain faults.

      This patch works around the issue by re-ordering our restoration of the
      AArch32 register aliases so that they happen before the AArch64 system
      registers. Ensuring that the registers are restored in this order
      guarantees that they will be correctly synchronised by the core.

      deallocations in udc_pci_probe() itself,
      since udc_pci_remove() is not suitabe to be called so early

      By the way, iounmap(dev->regs) is replaced by iounmap(dev->virt_addr)
      in udc_pci_remove() for clarity.

      usb: musb: ensure in peripheral mode when checking session

      The change ensures otg is not in a A- state when checking for VBUS in
      peripheral mode.

      musb_start() where VBUS checking is in can be called in many situations.
      One example is in babble recovery routine, in which otg is transitioning
      from A-HOST to A-WAIT-BCON, but VBUS discharge takes time, so
      musb->is_active could be set to 1 due to this improper checking, then it
      causes musb_bus_suspend() failed which leads to warning log message
      flooding.

      KVM: fix polling for guest halt continued even if disable it

      If there is already some polling ongoing, it's impossible to disable the
      polling, since as soon as somebody sets halt_poll_ns to 0, polling will
      never stop, as grow and shrink are only handled if halt_poll_ns is != 0.

      This patch fix it by reset vcpu->halt_poll_ns in order to stop polling
      when polling is disabled.

      thermal: power_allocator: don't require tzp to be present for the thermal 
zone

      Thermal zones created using thermal_zone_device_create() may not have
      tzp.  As the governor gets its parameters from there, allocate it while
      the governor is bound to the thermal zone so that it can operate in it.
      In this case, tzp is freed when the thermal zone switches to another
      governor.

      thermal: power_allocator: relax the requirement of two passive trip points

      The power allocator governor currently requires that the thermal zone
      has at least two passive trip points.  If there aren't, the governor
      refuses to bind to the thermal zone.

      This commit relaxes that requirement.  Now the governor will bind to all
      thermal zones regardless of how many trip points they have.

      thermal: power_allocator: relax the requirement of a sustainable_power in

      The power allocator governor currently requires that a sustainable power
      is passed as part of the thermal zone's thermal zone parameters.  If
      that parameter is not provided, it doesn't register with the thermal
      zone.

      While this parameter is strongly recommended for optimal performance, it
      doesn't need to be mandatory.  Relax the requirement and allow the
      governor to bind to thermal zones that don't provide it by estimating it
      from the cooling devices' power model.

      x86/platform/uv: Implement simple dump failover if kdump fails

      The ability to trigger a kdump using the system NMI command
      was added by

          commit 12ba6c990fab ("x86/UV: Add kdump to UV NMI handler")
          Author: Mike Travis <travis@xxxxxxx>
          Date:   Mon Sep 23 16:25:03 2013 -0500

      This is useful because when kdump is working the information
      gathered is more informative than the original per CPU stack
      traces or "dump" option.  However a number of things can go
      wrong with kdump and then the stack traces are more useful than
      nothing.

      The two most common reasons for kdump to not be available are:

        1) if a problem occurs during boot before the kdump service is
           started, or
        2) the kdump daemon failed to start.

      In either case the call to crash_kexec() returns unexpectedly.

      When this happens uv_nmi_kdump() also sets the
      uv_nmi_kexec_failed flag which causes the slave CPU's to also
      return to the NMI handler. Upon this unexpected return to the
      NMI handler, the NMI handler will revert to the "dump" action
      which uses show_regs() to obtain a process trace dump for all
      the CPU's.

      Other minor changes:
          The "dump" action now generates both the show_regs() stack trace
          and show instruction pointer information.  Whereas the "ips"
          action only shows instruction pointers for non-idle CPU's.  This
          is more like an abbreviated "ps" display.

      Depending on CONFIG_ARM64_HW_AFDBM, we use either bit 57 or 51 of the

      ARMv8.1, we can just use that bit regardless of the config option. That
      also matches what happens if a kernel configured with ARM64_HW_AFDBM=y
      is run on a CPU without the DBM functionality.

      arm64: Fix the pte_hw_dirty() check when AF/DBM is enabled

      Commit 2f4b829c625e ("arm64: Add support for hardware updates of the
      access and dirty pte bits") introduced support for handling hardware
      updates of the access flag and dirty status. The PTE is automatically
      dirtied in hardware (if supported) by clearing the PTE_RDONLY bit when
      the PTE_DBM/PTE_WRITE bit is set. The pte_hw_dirty() macro was added to
      detect a hardware dirtied pte. The pte_dirty() macro checks for both
      software PTE_DIRTY and pte_hw_dirty().

      Functions like pte_modify() clear the PTE_RDONLY bit since it is meant
      to be set in set_pte_at() when written to memory. In such cases,
      pte_hw_dirty() would return true even though such pte is clean. This
      patch changes pte_hw_dirty() to test the PTE_DBM/PTE_WRITE bit together
      with PTE_RDONLY.

      x86/fpu: Check to ensure increasing-offset xstate offsets

      The xstate CPUID leaves enumerate where each state component is
      inside the XSAVE buffer, along with the size of the entire
      buffer.  Our new XSAVE sanity-checking code extrapolates an
      expected _total_ buffer size by looking at the last component
      that it encounters.

      That method requires that the highest-numbered component also
      be the one with the highest offset.  This is a pretty safe
      assumption, but let's add some code to ensure it stays true.

      To make this check work correctly, we also need to ensure we
      only consider the offsets from enabled features because the
      offset register (ebx) will return 0 on unsupported features.

      This also means that we will preserve the -1's that we
      initialized xstate_offsets/sizes[] with.  That will help
      find bugs.

      x86/fpu: Correct and check XSAVE xstate size calculations

      Note: our xsaves support is currently broken and disabled.  This
      patch does not fix it, but it is an incremental improvement.

      This might be useful to someone backporting the entire set of
      XSAVES patches at some point, but it should not be backported
      alone.

      Ingo said he wanted something like this (bullets 2 and 3):

        http://lkml.kernel.org/r/20150808091508.GB32641@xxxxxxxxx

      There are currently two xsave buffer formats: standard and
      compacted.  The standard format is waht 'XSAVE' and 'XSAVEOPT'
      produce while 'XSAVES' and 'XSAVEC' produce a compacted-formet
      buffer.  (The kernel never uses XSAVEC)

      But, the XSAVES buffer *ALSO* contains "system state components"
      which are never saved by a plain XSAVE.  So, XSAVES has two
      things that might make its buffer differently-sized from an
      XSAVE-produced one.

      The current code assumes that an XSAVES buffer's size is simply
      the sum of the sizes of the (user) states which are supported.
      This seems to work in most cases, but it is not consistent with
      what the SDM says, and it breaks if we 'align' a component in
      the buffer.  The calculation is also unnecessary work since the
      CPU *tells* us the size of the buffer directly.

      This patch just reads the size of the buffer right out of the
      CPUID leaf instead of trying to derive it.

      But, blindly trusting the CPU like this is dangerous.  We add
      a verification pass in do_extra_xstate_size_checks() to ensure
      that the size we calculate matches with what we see from the
      hardware.  When it comes down to it, we trust but verify the
      CPU.

      hardware tells us about the sizes of the components.

      x86/fpu: Rework YMM definition

      We are about to rework all of the "extended state" definitions.
      This makes the 'ymm' naming consistent with the AVX-512 types
      we will introduce later.

      We also add a convenience type: "reg_128_bit" so that we do
      not have to spell out our arithmetic.

      x86/fpu/mpx: Rework MPX 'xstate' types

      MPX includes two separate "extended state components".  There is
      no real need to have an 'mpx_struct' because we never really
      manage the states together.

      We also separate out the actual data in 'mpx_bndcsr_state' from
      the padding.  We will shortly be checking the state sizes
      against our structures and need them to match.  For consistency,
      we also ensure to prefix these types with 'mpx_'.

      Lastly, we add some comments to mirror some of the descriptions
      in the Intel documents (SDM) of the various state components.

      x86/fpu: Add xfeature_enabled() helper instead of test_bit()

      We currently use test_bit() in a few places to see if an
      xfeature is enabled.  It ends up being a bit ugly because
      'xfeatures_mask' is a u64 and test_bit wants an 'unsigned long'
      so it requires a cast.  The *_bit() functions are also
      techincally atomic, which we have no need for here.

      So, remove the test_bit()s and replace with the new
      xfeature_enabled() helper.

      This also provides a central place to add a comment about the
      future need to support 'system xstates'.

      x86/fpu: Remove 'xfeature_nr'

      xfeature_nr ended up being initialized too late for me to
      use it in the "xsave size sanity check" patch which is
      later in the series.  I tried to move around its initialization
      but realized that it was just as easy to get rid of it.

      We only have 9 XFEATURES.  Instead of dynamically calculating
      and storing the last feature, just use the compile-time max:
      XFEATURES_NR_MAX.  Note that even with 'xfeatures_nr' we can
      had "holes" in the xfeatures_mask that we had to deal with.

      We also change a 'leaf' variable to be a plain 'i'.  Although
      it is used to grab a cpuid leaf in this one loop, all of the
      other loops just use an 'i' and I find it much more obvious
      to keep the naming consistent across all the similar loops.

      x86/fpu: Rework XSTATE_* macros to remove magic '2'

      The 'xstate.c' code has a bunch of references to '2'.  This
      is because we have a lot more work to do for the "extended"
      xstates than the "legacy" ones and state component 2 is the
      first "extended" state.

      This patch replaces all of the instances of '2' with
      FIRST_EXTENDED_XFEATURE, which clearly explains what is
      going on.

      x86/fpu: Rename XSAVE macros

      There are two concepts that have some confusing naming:
       1. Extended State Component numbers (currently called
          XFEATURE_BIT_*)
       2. Extended State Component masks (currently called XSTATE_*)

      The numbers are (currently) from 0-9.  State component 3 is the
      bounds registers for MPX, for instance.

      But when we want to enable "state component 3", we go set a bit
      in XCR0.  The bit we set is 1<<3.  We can check to see if a
      state component feature is enabled by looking at its bit.

      The current 'xfeature_bit's are at best xfeature bit _numbers_.
      Calling them bits is at best inconsistent with ending the enum
      list with 'XFEATURES_NR_MAX'.

      This patch renames the enum to be 'xfeature'.  These also
      happen to be what the Intel documentation calls a "state
      component".

      We also want to differentiate these from the "XSTATE_*" macros.
      The "XSTATE_*" macros are a mask, and we rename them to match.

      These macros are reasonably widely used so this patch is a
      wee bit big, but this really is just a rename.

      The only non-mechanical part of this is the

        s/XSTATE_EXTEND_MASK/XFEATURE_MASK_EXTEND/

      We need a better name for it, but that's another patch.

      x86/ldt: Fix small LDT allocation for Xen

      While the following commit:

        37868fe113 ("x86/ldt: Make modify_ldt synchronous")

      added a nice comment explaining that Xen needs page-aligned
      whole page chunks for guest descriptor tables, it then
      nevertheless used kzalloc() on the small size path.

      As I'm unaware of guarantees for kmalloc(PAGE_SIZE, ) to return
      page-aligned memory blocks, I believe this needs to be switched
      back to __get_free_page() (or better get_zeroed_page()).

      x86/fpu: Remove XSTATE_RESERVE

      The original purpose of XSTATE_RESERVE was to carve out space
      to store all of the possible extended state components that
      get saved with the XSAVE instruction(s).

      However, we are now almost entirely dynamically allocating
      the buffers we use for XSAVE by placing them at the end of
      the task_struct and them sizing them at boot.  The one
      exception for that is the init_task.

      The maximum extended state component size that we have today
      is on systems with space for AVX-512 and Memory Protection
      Keys: 2696 bytes.  We have reserved a PAGE_SIZE buffer in
      the init_task via fpregs_state->__padding.

      This check ensures that even if the component sizes or
      layout were changed (which we do not expect), that we will
      still not overflow the init_task's buffer.

      In the case that we detect we might overflow the buffer,
      we completely disable XSAVE support in the kernel and try
      to boot as if we had 'legacy x87 FPU' support in place.
      This is a crippled state without any of the XSAVE-enabled
      features (MPX, AVX, etc...).  But, it at least let us
      boot safely.

      When we want to _completely_ disable XSAVE support as far as
      the kernel is concerned, we have a big set of feature flags

      places where we do it to handle errors too.

      Move the code in to xstate.c, and put it in the xstate.h
      header.  We will use it in the next patch too.

      acpi/apei: Use appropriate pgprot_t to map GHES memory

      If the ACPI APEI firmware handles hardware error first (called
      "firmware first handling"), the firmware updates the GHES memory
      region with hardware error record (called "generic hardware
      error record"). Essentially the firmware writes hardware error
      records in the GHES memory region, triggers an NMI/interrupt,
      then the GHES driver goes off and grabs the error record from
      the GHES region.

      The kernel currently maps the GHES memory region as cacheable
      (PAGE_KERNEL) for all architectures. However, on some arm64
      platforms, there is a mismatch between how the kernel maps the
      GHES region (PAGE_KERNEL) and how the firmware maps it
      (EFI_MEMORY_UC, ie. uncacheable), leading to the possibility of
      the kernel GHES driver reading stale data from the cache when it
      receives the interrupt.

      With stale data being read, the kernel is unaware there is new
      hardware error to be handled when there actually is; this may
      lead to further damage in various scenarios, such as error
      propagation caused data corruption. If uncorrected error (such
      as double bit ECC error) happened in memory operation and if the
      kernel is unaware of such an event happening, errorneous data may
      be propagated to the disk.

      Instead GHES memory region should be mapped with page protection
      type according to what is returned from arch_apei_get_mem_attribute().

      Ensure there's enough data left prior calling pskb_may_pull(). If
      skb->data was already advanced, we'll call pskb_may_pull() with a
      negative value converted to unsigned int -- leading to a huge
      positive value. That won't matter in practice as pskb_may_pull()
      will likely fail in this case, but it leads to underflow reports on
      kernels handling such kind of over-/underflows, e.g. a PaX enabled
      kernel instrumented with the size_overflow plugin.

      drm/vmwgfx: Map the fifo as cached

      On the guest kernel side, previously the FIFO has been mapped write-
      combined. This has worked since VMs up to now has not honored the mapping
      type and mapped the FIFO cached anyway. Since the FIFO is accessed cached
      by the CPU on the virtual device side, this leads to inconsistent
      mappings once the guest starts to honor the mapping types.

      So ask for cached mappings when we map the FIFO. We do this by
      using ioremap_cache() instead of ioremap_wc(), and remove the MTRR setup.
      On the TTM side, MOBs, GMRs and VRAM buffers are already requesting
      cached mappings for kernel- and user-space.

      drm/vmwgfx: Fix up user_dmabuf refcounting

      If user space calls unreference on a user_dmabuf it will typically
      kill the struct ttm_base_object member which is responsible for the
      user-space visibility. However the dmabuf part may still be alive and
      refcounted. In some situations, like for shared guest-backed surface
      referencing/opening, the driver may try to reference the
      struct ttm_base_object member again, causing an immediate kernel warning
      and a later kernel NULL pointer dereference.

      Fix this by always maintaining a reference on the struct
      ttm_base_object member, in situations where it might subsequently be
      referenced.

      Documentation: gpio: board: describe the con_id parameter

      The con_id parameter has to match the GPIO description and is 
automatically
      extended by the GPIO suffix if not NULL. I had to look into the code to
      understand this and properly find the GPIO I've been looking for, so 
document
      this.

      gpio: Propagate errors from chip->get()

      It's possible to have gpio chips hanging off unreliable remote buses
      where the get() operation will fail to acquire a readout of the current
      gpio state. Propagate these errors to the consumer so that they can
      act on, retry or ignore these failing reads, instead of treating them as
      the line being held high.

      drivers: sh: Disable PM runtime for multi-platform ARM with genpd

      If the default PM Domain using PM_CLK is used for PM runtime, the real
      Clock Domain cannot be registered from DT later.

      Hence do not enable it when running a multi-platform kernel with genpd
      support on R-Car or RZ.  The CPG/MSTP Clock Domain driver will take care
      of PM runtime management of the module clocks.

      Now most multi-platform ARM shmobile platforms (SH-Mobile, R-Mobile,
      R-Car, RZ) use DT-based PM Domains to take care of PM runtime management
      of the module clocks, simplify the platform logic by replacing the
      explicit SoC checks by a single check for the presence of MSTP clocks in
      DT.

      Backwards-compatiblity with old DTs (mainly for R-Car Gen2) is provided
      by checking for the presence of a "#power-domain-cells" property in DT.

      The default PM Domain is still needed for:
        - backwards-compatibility with old DTs that lack PM Domain properties,
        - the CONFIG_PM=n case,
        - legacy (non-DT) ARM/shmobile platforms without genpd support
          (r8a7778, r8a7779),
        - legacy SuperH.

      ARM: EXYNOS: reset Little cores when cpu is up

      The cpu booting of exynos5422 has been still broken since we discussed
      it in last year[1]. This patch is inspired from Odroid XU3
      code (Actually, it was from samsung exynos vendor kernel)[2]. This weird
      reset code was founded exynos5420 octa cores series SoCs and only
      required for the first boot core is the Little core (Cortex A7).
      Some of the exynos5420 boards and all of the exynos5422 boards will 
require
      this code.

      There is two ways to check the little core is the first cpu. One is
      checking GPG2CON[1] GPIO value and the other is checking the cluster
      number of the first cpu. I selected the latter because it's more easier
      than the former.

      In cases where visorbus is compiled directly into the kernel, if
      visorbus registration fails for any reason, it is still possible for
      other drivers to call visorbus_register_visor_driver(), which could
      cause an oops. Prevent this by saving the result of the call to

      hasn't been registered successfully.

      staging: fbtft: replace master->setup() with spi_setup()

      Calling the setup of the SPI master directly causes a NULL pointer
      dereference with master drivers without a separate setup function.
      This problem is reproduceable on ARM MXS platform.

      So fix this issue by using spi_setup() instead.

      Since the result of the setup function isn't adequate to check
      9-bit SPI support, we better check bits_per_word_mask. Btw this
      change avoids a NULL pointer dereference with master drivers

      staging/android: Update ION TODO per LPC discussion

      We discussed a bit with the folks on the Cc: list below what to do
      with ION. Two big take-aways:

      - High-performance drivers (like gpus) always want to play tricks with
        coherency and will lie to the dma api (radeon, nouveau, i915 gpu
        drivers all do so in upstream). What needs to be done here is fill
        gaps in dma-buf so that we can do this without breaking the dma-api
        expections of other clients like v4l. The consesus is that hw won't
        stop needing these tricks anytime soon.

      - Placement constraints for shared buffers won't be solved any other
        way than through something platform-specific like ion with
        platform-specific knowledge in userspace in something like gralloc.
        For general-purpose devices where this assumption would be painful
        for userspace (like servers) the consensus is that such devices will
        have proper MMUs where placement constraint handling is fairly
        irrelevant.

      Hence it is reasonable to destage ion as-is without changing the
      overall design to enable these use-cases and just fixing up a these
      few fairly minor things. Since there won't relly be an open-source
      userspace for ion (and hence drm maintainers won't take it) the
      proposal is to eventually move it to drivers/android/ion.[hc]. Laura
      would be ok with being maintainer once this is all done and ion is
      destaged.

      Note that Thiago is working on exposing the cpu cache flushing for
      cpu access from userspace through mmaps so this is alread in progress.
      Also adding him to the Cc: list.

      v2: Add ION_IOC_IMPORT to the list of ioctl that probably should go.

      perf header: Fixup reading of HEADER_NRCPUS feature

      The original patch introducing this header wrote the number of CPUs 
available
      and online in one order and then swapped those values when reading, fix 
it.

      Before:

        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 4
        # echo 0 > /sys/devices/system/cpu/cpu2/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 3
        # echo 0 > /sys/devices/system/cpu/cpu1/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 2

      After the fix, bringing back the CPUs online:

        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 2
        # nrcpus avail : 4
        # echo 1 > /sys/devices/system/cpu/cpu2/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 3
        # nrcpus avail : 4
        # echo 1 > /sys/devices/system/cpu/cpu1/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4

      ARM: pxa: fix DFI bus lockups on startup

      After the conversion of pxa architecture to common clock framework, the
      NAND clock can be disabled on startup if no nand driver claims it.

      In this case, it happens that if the bootloader used the NAND and set
      the DFI arbitration bit, the next access to a static memory controller
      area, such as an ethernet card, the system bus will stall, and the core
      will be stalled forever.

      Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit
      will be enabled the pxa3xx-nand driver on need anyway. The only left
      requirement is that upon pxa3xx-nand removal, the bit should be cleared
      before the clock is disabled.

      perf/core: Drop PERF_EVENT_TXN

      We currently use PERF_EVENT_TXN flag to determine if we are in the middle
      of a transaction. If in a transaction, we defer the schedulability checks
      from pmu->add() operation to the pmu->commit() operation.

      Now that we have "transaction types" (PERF_PMU_TXN_ADD, PERF_PMU_TXN_READ)
      we can use the type to determine if we are in a transaction and drop the
      PERF_EVENT_TXN flag.

      When PERF_EVENT_TXN is dropped, the cpuhw->group_flag on some 
architectures
      becomes unused, so drop that field as well.

      This is an extension of the Powerpc patch from Peter Zijlstra to s390,
      Sparc and x86 architectures.

      powerpc, perf/powerpc/hv-24x7: Use PMU_TXN_READ interface

      The 24x7 counters in Powerpc allow monitoring a large number of counters
      simultaneously. They also allow reading several counters in a single
      HCALL so we can get a more consistent snapshot of the system.

      Use the PMU's transaction interface to monitor and read several event
      counters at once. The idea is that users can group several 24x7 events
      into a single group of events. We use the following logic to submit
      the group of events to the PMU and read the values:

        pmu->start_txn()                // Initialize before first event

        for each event in group
                pmu->read(event);       // Queue each event to be read

        pmu->commit_txn()               // Read/update all queuedcounters

      The ->commit_txn() also updates the event counts in the respective
      perf_event objects.  The perf subsystem can then directly get the
      event counts from the perf_event and can avoid submitting a new
      ->read() request to the PMU.

      Thanks to input from Peter Zijlstra.

      perf/core: Define PERF_PMU_TXN_READ interface

      Define a new PERF_PMU_TXN_READ interface to read a group of counters
      at once.

              pmu->start_txn()                // Initialize before first event

              for each event in group
                      pmu->read(event);       // Queue each event to be read

              rc = pmu->commit_txn()          // Read/update all queued counters

      Note that we use this interface with all PMUs.  PMUs that implement this
      interface use the ->read() operation to _queue_ the counters to be read
      and use ->commit_txn() to actually read all the queued counters at once.

      PMUs that don't implement PERF_PMU_TXN_READ ignore ->start_txn() and
      ->commit_txn() and continue to read counters one at a time.

      perf/core: Add return value for perf_event_read()

      When we implement the ability to read several counters at once (using
      the PERF_PMU_TXN_READ transaction interface), perf_event_read() can
      fail when the 'group' parameter is true (eg: trying to read too many
      events at once).

      For now, have perf_event_read() return an integer. Ignore the return
      value when the 'group' parameter is false.

      perf/core: Invert perf_read_group() loops

      In order to enable the use of perf_event_read(.group = true), we need
      to invert the sibling-child loop nesting of perf_read_group().

      Currently we iterate the child list for each sibling, this precludes
      using group reads. Flip things around so we iterate each group for
      each child.

      perf/core: Split perf_event_read() and perf_event_count()

      perf_event_read() does two things:

        - call the PMU to read/update the counter value, and
        - compute the total count of the event and its children

      Not all callers need both. perf_event_reset() for instance needs the
      first piece but doesn't need the second.  Similarly, when we implement
      the ability to read a group of events using the transaction interface,
      we would need the two pieces done independently.

      Break up perf_event_read() and have it just read/update the counter
      and have the callers compute the total count if necessary.

      perf/core: Add a 'flags' parameter to the PMU transactional interfaces

      Currently, the PMU interface allows reading only one counter at a time.
      But some PMUs like the 24x7 counters in Power, support reading several
      counters at once. To leveage this functionality, extend the transaction
      interface to support a "transaction type".

      The first type, PERF_PMU_TXN_ADD, refers to the existing transactions,
      i.e. used to _schedule_ all the events on the PMU as a group. A second
      transaction type, PERF_PMU_TXN_READ, will be used in a follow-on patch,
      by the 24x7 counters to read several counters at once.

      Extend the transaction interfaces to the PMU to accept a 'txn_flags'
      parameter and use this parameter to ignore any transactions that are
      not of type PERF_PMU_TXN_ADD.

      Thanks to Peter Zijlstra for his input.

      If KVM does not support INTEL_PT, guest MSR_IA32_RTIT_CTL reading will
      produce host warning like "kvm [2469]: vcpu0 unhandled rdmsr: 0x570".

      Guest can determine whether the CPU supports Intel_PT according to CPUID,

      perf/x86/intel: Fix LBR callstack issue caused by FREEZE_LBRS_ON_PMI

      This patch fixes an issue which introduced by commit
      1a78d93750bb5f61abdc59a91fc3bd06a214542a ("perf/x86/intel: Streamline
      LBR MSR handling in PMI").

      The old patch not only avoids writing LBR_SELECT MSR in PMI, but also
      avoids updating lbr_select variable. So in PMI, FREEZE_LBRS_ON_PMI bit
      is always mistakenly set for IA32_DEBUGCTLMSR MSR, which causes
      superfluous increase/decrease of LBR_TOS when collecting LBR callstack.

      perf/x86/intel/bts: Disallow use by unprivileged users on paranoid systems

      BTS leaks kernel addresses even in userspace-only mode due to imprecise IP
      sampling, so sometimes syscall entry points or page fault handler 
addresses
      end up in a userspace trace.

      Now, intel_bts driver exports trace data zero-copy, it does not scan 
through
      it to filter out the kernel addresses and it's would be a O(n) job.

      To work around this situation, this patch forbids the use of intel_bts
      driver by unprivileged users on systems with the paranoid setting above 
the
      (kernel's) default "1", which still allows kernel profiling. In other 
words,
      using intel_bts driver implies kernel tracing, regardless of the
      "exclude_kernel" attribute setting.

      perf/x86/intel/ds: Work around BTS leaking kernel addresses

      BTS leaks kernel addresses even in userspace-only mode due to imprecise IP
      sampling, so sometimes syscall entry points or page fault handler 
addresses
      end up in a userspace trace.

      Since this driver uses a relatively small buffer for BTS records and it 
has
      to iterate through them anyway, it can also take on the additional job of
      filtering out the records that contain kernel addresses when kernel space
      tracing is not enabled.

      This patch changes the bts code to skip the offending records from perf
      output. In order to request the exact amount of space on the ring buffer,
      we need to do an extra pass through the records to know how many there are
      of the valid ones, but considering the small size of the buffer, this 
extra
      pass adds very little overhead to the nmi handler. This way we won't end
      up with awkward IP samples with zero IPs in the perf stream.

      perf/x86: Improve accuracy of perf/sched clock

      When TSC is stable perf/sched clock is based on it.
      However the conversion from cycles to nanoseconds
      is not as accurate as it could be.  Because
      CYC2NS_SCALE_FACTOR is 10, the accuracy is +/- 1/2048

      The change is to calculate the maximum shift that
      results in a multiplier that is still a 32-bit number.
      For example all frequencies over 1 GHz will have
      a shift of 32, making the accuracy of the conversion
      +/- 1/(2^33).  That is achieved by using the
      'clocks_calc_mult_shift()' function.

      locking/atomics, cmpxchg: Privatize the inclusion of asm/cmpxchg.h

      After commit:

        654672d4ba1a ("locking/atomics: Add _{acquire|release|relaxed}() 
variants of some atomic operations")

      Architectures may only provide {cmp,}xchg_relaxed definitions in
      asm/cmpxchg.h. Other variants, such as {cmp,}xchg, may be built in
      linux/atomic.h, which means simply including asm/cmpxchg.h may not get
      the definitions of all the{cmp,}xchg variants.

      Therefore, we should privatize the inclusions of asm/cmpxchg.h to
      keep it only included in arch/* and replace the inclusions outside
      with linux/atomic.h

      time: Fix timekeeping_freqadjust()'s incorrect use of abs() instead of 
abs64()

      The internal clocksteering done for fine-grained error
      correction uses a logarithmic approximation, so any time
      adjtimex() adjusts the clock steering, timekeeping_freqadjust()
      quickly approximates the correct clock frequency over a series
      of ticks.

      Unfortunately, the logic in timekeeping_freqadjust(), introduced
      in commit:

        dc491596f639 ("timekeeping: Rework frequency adjustments to work better 
w/ nohz")

      used the abs() function with a s64 error value to calculate the
      size of the approximated adjustment to be made.

      Per include/linux/kernel.h:

        "abs() should not be used for 64-bit types (s64, u64, long long) - use 
abs64()".

      Thus on 32-bit platforms, this resulted in the clocksteering to
      take a quite dampended random walk trying to converge on the
      proper frequency, which caused the adjustments to be made much
      slower then intended (most easily observed when large
      adjustments are made).

      This patch fixes the issue by using abs64() instead.

      sched/fair: Optimize per entity utilization tracking

      Currently the load_{sum,avg} and util_{sum,avg} tracking is asymmetric
      in that load tracking gets a 2^10 unit from the weight, but util gets
      no such factor.

      This results in more lost bits for util scaling and asymmetric scaling
      rules.

      Fix this by removing shifts, such that we gain the 2^10 factor from
      scaling. There is no risk of overflowing the u32 as the max value is
      now LOAD_AVG_MAX << 10, which is still well below UINT_MAX.

      This further entangles the assumption that both LOAD and CAPACITY
      shifts are the same (and 10) so put in an assertion for that.

      This fixes the math for the LOAD_RESOLUTION != 0 case.

      sched/fair: Optimize __update_load_avg()

      Prior to this patch; the line:

        scaled_delta_w = (delta_w * 1024) >> 10;

      which is the result of the default arch_scale_freq_capacity()
      function, turns into:

          1b03: 49 89 d1                mov    %rdx,%r9
          1b06: 49 c1 e1 0a             shl    $0xa,%r9
          1b0a: 49 c1 e9 0a             shr    $0xa,%r9

      Which is silly; when made unsigned int, GCC recognises this as
      pointless ops and fails to emit them (confirmed on 4.9.3 and 5.1.1).

      Furthermore, afaict unsigned is actually the correct type for these
      fields anyway, as we've explicitly ruled out negative delta's earlier
      in this function.

      sched/fair: Make utilization tracking CPU scale-invariant

      Besides the existing frequency scale-invariance correction factor, apply
      CPU scale-invariance correction factor to utilization tracking to
      compensate for any differences in compute capacity. This could be due to
      micro-architectural differences (i.e. instructions per seconds) between
      cpus in HMP systems (e.g. big.LITTLE), and/or differences in the current
      maximum frequency supported by individual cpus in SMP systems. In the
      existing implementation utilization isn't comparable between cpus as it
      is relative to the capacity of each individual CPU.

      Each segment of the sched_avg.util_sum geometric series is now scaled
      by the CPU performance factor too so the sched_avg.util_avg of each
      sched entity will be invariant from the particular CPU of the HMP/SMP
      system on which the sched entity is scheduled.

      With this patch, the utilization of a CPU stays relative to the max CPU
      performance of the fastest CPU in the system.

      In contrast to utilization (sched_avg.util_sum), load
      (sched_avg.load_sum) should not be scaled by compute capacity. The
      utilization metric is based on running time which only makes sense when
      cpus are _not_ fully utilized (utilization cannot go beyond 100% even if
      more tasks are added), where load is runnable time which isn't limited
      by the capacity of the CPU and therefore is a better metric for
      overloaded scenarios. If we run two nice-0 busy loops on two cpus with
      different compute capacity their load should be similar since their
      compute demands are the same. We have to assume that the compute demand
      of any task running on a fully utilized CPU (no spare cycles = 100%
      utilization) is high and the same no matter of the compute capacity of
      its current CPU, hence we shouldn't scale load by CPU capacity.

      sched/fair: Convert arch_scale_cpu_capacity() from weak function to 
#define

      Bring arch_scale_cpu_capacity() in line with the recent change of its
      arch_scale_freq_capacity() sibling in commit dfbca41f3479 ("sched:
      Optimize freq invariant accounting") from weak function to #define to
      allow inlining of the function.

      While at it, remove the ARCH_CAPACITY sched_feature as well. With the
      change to #define there isn't a straightforward way to allow runtime
      switch between an arch implementation and the default implementation of
      arch_scale_cpu_capacity() using sched_feature. The default was to use
      the arch-specific implementation, but only the arm architecture provides
      one and that is essentially equivalent to the default implementation.

      Each segment of the sched_avg.load_sum geometric series is now scaled by

      will be invariant from frequency scaling.

      well.

      sched/numa: Remove the NUMA sched_feature

      Variable sched_numa_balancing is available for both CONFIG_SCHED_DEBUG
      and !CONFIG_SCHED_DEBUG. All code paths now check for
      sched_numa_balancing. Hence remove sched_feat(NUMA).

      sched/numa: Disable sched_numa_balancing on UMA systems

      Commit 2a1ed24 ("sched/numa: Prefer NUMA hotness over cache hotness")
      sets sched feature NUMA to true. However this can enable NUMA hinting
      faults on a UMA system.

      This commit ensures that NUMA hinting faults occur only on a NUMA system
      by setting/resetting sched_numa_balancing.

      This commit:

        - Makes sched_numa_balancing common to CONFIG_SCHED_DEBUG and
          !CONFIG_SCHED_DEBUG. Earlier it was only in !CONFIG_SCHED_DEBUG.

        - Checks for sched_numa_balancing instead of sched_feat(NUMA).

      sched/fair: Fix nohz.next_balance update

      Since commit:

        d4573c3e1c99 ("sched: Improve load balancing in the presence of idle 
CPUs")

      the ILB CPU starts with the idle load balancing of other idle CPUs and
      finishes with itself in order to speed up the spread of tasks in all
      idle CPUs.

      The this_rq->next_balance is still used in nohz_idle_balance() as an
      intermediate step to gather the shortest next balance before updating
      nohz.next_balance. But the former has not been updated yet and is likely 
to
      be set with the current jiffies. As a result, the nohz.next_balance will 
be
      set with current jiffies instead of the real next balance date. This
      generates spurious kicks of nohz ilde balance.

      nohz_idle_balance() must set the nohz.next_balance without taking into
      account this_rq->next_balance which is not updated yet. Then, this_rq will
      update nohz.next_update with its next_balance once updated and if 
necessary.

      sched/fair: Unify switched_{from,to}_fair() and task_move_group_fair()

      By observing that switched_from_fair() detaches from a runqueue, and
      switched_to_fair() attaches to a runqueue, we can see that
      task_move_group_fair() is one followed by the other with flipping the
      runqueue in between.

      Therefore extract all the common bits and implement all three
      functions in terms of them.

      This should fix a few corner cases wrt. vruntime normalization; where,
      when we take a task off of a runqueue we convert to an approximation
      of lag by subtracting min_vruntime, and when placing a task on the a
      runqueue to the reverse.

  Author: Byungchul Park <byungchul.park@xxxxxxx>
  Date:   Thu Aug 20 20:21:59 2015 +0900

      sched/fair: Fix switched_to_fair()'s per entity load tracking

      Where switched_from_fair() will remove the entity's load from the
      runqueue, switched_to_fair() does not currently add it back. This
      means that when a task leaves the fair class for a short duration; say
      because of PI; we loose its load contribution.

      This can ripple forward and disturb the load tracking because other
      operations (enqueue, dequeue) assume its factored in. Only once the
      runqueue empties will the load tracking recover.

      When we add it back in, age the per entity average to match up with
      the runqueue age. This has the obvious problem that if the task leaves
      the fair class for a significant time, the load will age to 0.

      Employ the normal migration rule for inter-runqueue moves in
      task_move_group_fair(). Again, there is the obvious problem of the
      task migrating while not in the fair class.

      The alternative solution would be to to omit the chunk in
      attach_entity_load_avg(), which would effectively reset the timestamp
      and use whatever avg there was.

      sched/fair: Have task_move_group_fair() unconditionally add the entity 
load to the runqueue

      Currently we conditionally add the entity load to the rq when moving
      the task between cgroups.

      This doesn't make sense as we always 'migrate' the task between
      cgroups, so we should always migrate the load too.

      [ The history here is that we used to only migrate the blocked load
        which was only meaningfull when !queued. ]

      [CIFS] mount option sec=none not displayed properly in /proc/mounts

      When the user specifies "sec=none" in a cifs mount, we set
      sec_type as unspecified (and set a flag and the username will be
      null) rather than setting sectype as "none" so

      irda: ali-ircc: Fix deadlock in ali_ircc_sir_change_speed()

      ali_ircc_sir_change_speed() is always called with self->lock held,
      so acquiring the lock inside it leads to unavoidable deadlock.

      Call graph:

        ali_ircc_fir_hard_xmit() under spin_lock_irqsave(&self->lock, flags);

      bridge: fix igmpv3 / mldv2 report parsing

      With the newly introduced helper functions the skb pulling is hidden in
      the checksumming function - and undone before returning to the caller.

      The IGMPv3 and MLDv2 report parsing functions in the bridge still
      assumed that the skb is pointing to the beginning of the IGMP/MLD
      message while it is now kept at the beginning of the IPv4/6 header,
      breaking the message parsing and creating packet loss.

      Fixing this by taking the offset between IP and IGMP/MLD header into
      account, too.

      bnx2x: use ktime_get_seconds() for timestamp

      commit c48f350ff5e7 "bnx2x: Add MFW dump support" added the
      bnx2x_update_mfw_dump() function that reads the current time and stores
      it in a 32-bit field that gets passed into a buffer in a fixed format.

      This is potentially broken when the epoch overflows in 2038, and
      otherwise overflows in 2106. As we're trying to avoid uses of
      struct timeval for this reason, I noticed the addition of this
      function, and tried to rewrite it in a way that is more explicit
      about the overflow and that will keep working once we deprecate
      struct timeval.

      I assume that it is not possible to change the ABI any more, otherwise
      we should try to use a 64-bit field for the seconds right away.

      sctp: fix race on protocol/netns initialization

      Consider sctp module is unloaded and is being requested because an user
      is creating a sctp socket.

      During initialization, sctp will add the new protocol type and then
      initialize pernet subsys:

              status = sctp_v4_protosw_init();
              if (status)
                      goto err_protosw_init;

              status = sctp_v6_protosw_init();
              if (status)
                      goto err_v6_protosw_init;

              status = register_pernet_subsys(&sctp_net_ops);

      The problem is that after those calls to sctp_v{4,6}_protosw_init(), it
      is possible for userspace to create SCTP sockets like if the module is
      already fully loaded. If that happens, one of the possible effects is
      that we will have readers for net->sctp.local_addr_list list earlier
      than expected and sctp_net_init() does not take precautions while
      dealing with that list, leading to a potential panic but not limited to
      that, as sctp_sock_init() will copy a bunch of blank/partially
      initialized values from net->sctp.

      The race happens like this:

           CPU 0                           |  CPU 1
        socket()                           |

          inet_create                      |  __sock_create
           list_for_each_entry_rcu(        |
              answer, &inetsw[sock->type], |
              list) {                      |   inet_create
            /* no hits */                  |
           if (unlikely(err)) {            |
            ...                            |
            request_module()               |
            /* socket creation is blocked  |
             * the module is fully loaded  |
             */                            |
             sctp_init                     |
              sctp_v4_protosw_init         |
               inet_register_protosw       |
                list_add_rcu(&p->list,     |
                             last_perm);   |
                                           |  list_for_each_entry_rcu(
                                           |     answer, &inetsw[sock->type],
              sctp_v6_protosw_init         |     list) {
                                           |     /* hit, so assumes protocol
                                           |      * is already loaded
                                           |      */
                                           |  /* socket creation continues
                                           |   * before netns is initialized
                                           |   */
              register_pernet_subsys       |

      Simply inverting the initialization order between
      register_pernet_subsys() and sctp_v4_protosw_init() is not possible
      because register_pernet_subsys() will create a control sctp socket, so
      the protocol must be already visible by then. Deferring the socket
      creation to a work-queue is not good specially because we loose the
      ability to handle its errors.

      So, as suggested by Vlad, the fix is to split netns initialization in
      two moments: defaults and control socket, so that the defaults are
      already loaded by when we register the protocol, while control socket
      initialization is kept at the same moment it is today.

      ebpf: emit correct src_reg for conditional jumps

      Instead of always emitting BPF_REG_X, let's emit BPF_REG_X only when the
      source actually is BPF_X. This causes programs generated by the classic
      converter to not be importable via bpf(), as the eBPF verifier checks that
      the src_reg is correct or 0. While not a problem yet, this will be a
      problem when BPF_PROG_DUMP lands, and we can potentially dump and 
re-import
      programs generated by the converter.

      netlink, mmap: transform mmap skb into full skb on taps

      Ken-ichirou reported that running netlink in mmap mode for receive in
      combination with nlmon will throw a NULL pointer dereference in
      __kfree_skb() on nlmon_xmit(), in my case I can also trigger an "unable
      to handle kernel paging request". The problem is the skb_clone() in
      __netlink_deliver_tap_skb() for skbs that are mmaped.

      I.e. the cloned skb doesn't have a destructor, whereas the mmap netlink
      skb has it pointed to netlink_skb_destructor(), set in the handler
      netlink_ring_setup_skb(). There, skb->head is being set to NULL, so
      that in such cases, __kfree_skb() doesn't perform a skb_release_data()
      via skb_release_all(), where skb->head is possibly being freed through
      kfree(head) into slab allocator, although netlink mmap skb->head points
      to the mmap buffer. Similarly, the same has to be done also for large
      netlink skbs where the data area is vmalloced. Therefore, as discussed,
      make a copy for these rather rare cases for now. This fixes the issue
      on my and Ken-ichirou's test-cases.

      ARM: 8431/1: fix alignement of __bug_table section entries

      On old ARM chips, unaligned accesses to memory are not trapped and

      arm/xen: Enable user access to the kernel before issuing a privcmd call

      When Xen is copying data to/from the guest it will check if the kernel
      has the right to do the access. If not, the hypercall will return an
      error.

      After the commit a5e090acbf545c0a3b04080f8a488b17ec41fe02 "ARM:
      software-based privileged-no-access support", the kernel can't access
      any longer the user space by default. This will result to fail on every
      hypercall made by the userspace (i.e via privcmd).

      We have to enable the userspace access and then restore the correct
      permission every time the privcmd is used to made an hypercall.

      I didn't find generic helpers to do a these operations, so the change
      is only arm32 specific.

      ARM: domains: add memory dependencies to get_domain/set_domain

      We need to have memory dependencies on get_domain/set_domain to avoid
      the compiler over-optimising these inline assembly instructions.

      Loads/stores must not be reordered across a set_domain(), so introduce
      a compiler barrier for that assembly.

      The value of get_domain() must not be cached across a set_domain(), but
      we still want to allow the compiler to optimise it away.  Introduce a
      dependency on current_thread_info()->cpu_domain to avoid this; the new
      memory clobber in set_domain() should therefore cause the compiler to
      re-load this.  The other advantage of using this is we should have its
      address in the register set already, or very soon after at most call
      sites.

      block: blkg_destroy_all() should clear q->root_blkg and ->root_rl.blkg

      While making the root blkg unconditional, ec13b1d6f0a0 ("blkcg: always
      create the blkcg_gq for the root blkcg") removed the part which clears
      q->root_blkg and ->root_rl.blkg during q exit.  This leaves the two
      pointers dangling after blkg_destroy_all().  blk-throttle exit path
      performs blkg traversals and dereferences ->root_blkg and can lead to
      the following oops.

      While the bug is a straigh-forward use-after-free bug, it is tricky to
      reproduce because blkg release is RCU protected and the rest of exit
      path usually finishes before RCU grace period.

      This patch fixes the bug by updating blkg_destro_all() to clear
      q->root_blkg and ->root_rl.blkg.

      block: Copy a user iovec if it includes gaps

      For drivers that don't support gaps in the SG lists handed to
      them we must bounce (copy the user buffers) and pass a bio that
      does not include gaps. This doesn't matter for any current user,
      but will help to allow iser which can't handle gaps to use the
      block virtual boundary instead of using driver-local bounce
      buffering when handling SG_IO commands.

      block: Refuse adding appending a gapped integrity page to a bio

      This is only theoretical at the moment given that the only
      subsystems that generate integrity payloads are the block layer
      itself and the scsi target (which generate well aligned integrity
      payloads). But when we will expose integrity meta-data to user-space,
      we'll need to refuse appending a page with a gap (if the queue
      virtual boundary is set).

      CIFS: fix type confusion in copy offload ioctl

      This might lead to local privilege escalation (code execution as
      kernel) for systems where the following conditions are met:

       - CONFIG_CIFS_SMB2 and CONFIG_CIFS_POSIX are enabled
       - a cifs filesystem is mounted where:
        - the mount option "vers" was used and set to a value >=2.0
        - the attacker has write access to at least one file on the filesystem

      To attack this, an attacker would have to guess the target_tcon
      pointer (but guessing wrong doesn't cause a crash, it just returns an
      error code) and win a narrow race.

      As Peterz pointed out:

      | So the normal rules for changing task_struct::cpus_allowed are holding
      | both pi_lock and rq->lock, such that holding either stabilizes the mask.
      |
      | This is so that wakeup can happen without rq->lock and load-balance
      | without pi_lock.
      |
      | From this we already get the relaxation that we can omit acquiring
      | rq->lock if the task is not on the rq, because in that case
      | load-balancing will not apply to it.
      |
      | ** these are the rules currently tested in do_set_cpus_allowed() **
      |
      | Now, since __set_cpus_allowed_ptr() uses task_rq_lock() which
      | unconditionally acquires both locks, we could get away with holding just
      | rq->lock when on_rq for modification because that'd still exclude
      | __set_cpus_allowed_ptr(), it would also work against
      | __kthread_bind_mask() because that assumes !on_rq.
      |
      | That said, this is all somewhat fragile.
      |
      | Now, I don't think dropping rq->lock is quite as disastrous as it
      | usually is because !cpu_active at this point, which means load-balance
      | will not interfere, but that too is somewhat fragile.
      |
      | So we end up with a choice of two fragile..

      This patch fixes it by following the rules for changing
      task_struct::cpus_allowed with both pi_lock and rq->lock held.

      Dave ran into horrible performance on a VM without PARAVIRT_SPINLOCKS
      set and Linus noted that the test-and-set implementation was retarded.

      One should spin on the variable with a load, not a RMW.

      While there, remove 'queued' from the name, as the lock isn't queued
      at all, but a simple test-and-set.

      PM / devfreq: exynos-ppmu: Add the support of PPMUv2 for Exynos5433

      This patch adds the support for PPMU (Platform Performance Monitoring 
Unit)
      version 2.0 for Exynos5433 SoC. Exynos5433 SoC must need PPMUv2 which is
      quite different from PPMUv1.1. The exynos-ppmu.c driver supports both 
PPMUv1.1
      and PPMUv2.

      toshiba_acpi: Fix hotkeys registration on some toshiba models

      Commit a2b3471b5b13 ("toshiba_acpi: Use the Hotkey Event Type function
      for keymap choosing") changed the *setup_keyboard function to query for
      the Hotkey Event Type to help choose the correct keymap, but turns out
      that here are certain Toshiba models out there not implementing this
      feature, and thus, failing to continue the input device registration and
      leaving such laptops without hotkey support.

      This patch changes such check, and instead of returning an error if
      the Hotkey Event Type is not present, we simply inform userspace about it,
      changing the message printed from err to notice, making the function
      responsible for registering the input device to continue.

      This issue was found on a Toshiba Portege Z30-B, but there might be
      some other models out there affected by this regression as well.

      Currently the registration of critical clocks is done in the function
      shared between rk3066 and rk3188 clock trees. That results in them
      getting handled maybe before all of them are registered.

      Therefore move the critical clock handling down to the end of the soc-

      before they're maybe handled as critical clock.

      string: provide strscpy()

      The strscpy() API is intended to be used instead of strlcpy(),
      and instead of most uses of strncpy().

      - Unlike strlcpy(), it doesn't read from memory beyond (src + size).

      - Unlike strlcpy() or strncpy(), the API provides an easy way to check
        for destination buffer overflow: an -E2BIG error return value.

      - The provided implementation is robust in the face of the source
        buffer being asynchronously changed during the copy, unlike the
        current implementation of strlcpy().

      - Unlike strncpy(), the destination buffer will be NUL-terminated
        if the string in the source buffer is too long.

      - Also unlike strncpy(), the destination buffer will not be updated
        beyond the NUL termination, avoiding strncpy's behavior of zeroing
        the entire tail end of the destination buffer.  (A memset() after
        the strscpy() can be used if this behavior is desired.)

      - The implementation should be reasonably performant on all
        platforms since it uses the asm/word-at-a-time.h API rather than
        simple byte copy.  Kernel-to-kernel string copy is not considered
        to be performance critical in any case.

      wmi: Remove private %pUL implementation

      The work performed by wmi_gtoa is equivalent to simply sprintf(out,
      "%pUL", in), so one could replace its body by this. However, most
      users feed the result directly as a %s argument to some other function
      which also understands the %p extensions (they all ultimately use
      vsnprintf), so we can eliminate some stack buffers and quite a bit of
      code by just using %pUL directly.

      In wmi_dev_uevent I'm not sure whether there's room for a
      nul-terminator in env->buf, so I've just replaced wmi_gtoa with the
      equivalent sprintf call.

      Btrfs: remove unnecessary locking of cleaner_mutex to avoid deadlock

      After commmit e44163e17796 ("btrfs: explictly delete unused block groups
      in close_ctree and ro-remount"), added in the 4.3 merge window, we have
      calls to btrfs_delete_unused_bgs() while holding the cleaner_mutex.
      This can cause a deadlock with a concurrent block group relocation (when
      a filesystem balance or shrink operation is in progress for example)
      because btrfs_delete_unused_bgs() locks delete_unused_bgs_mutex and the
      relocation path locks first delete_unused_bgs_mutex and then it locks
      cleaner_mutex, resulting in a classic ABBA deadlock:

               CPU 0                                        CPU 1

      lock fs_info->cleaner_mutex

                                                 __btrfs_balance() || 
btrfs_shrink_device()
                                                   lock 
fs_info->delete_unused_bgs_mutex
                                                   btrfs_relocate_chunk()
                                                     
btrfs_relocate_block_group()
                                                       lock 
fs_info->cleaner_mutex
      btrfs_delete_unused_bgs()
        lock fs_info->delete_unused_bgs_mutex

      Fix this by not taking the cleaner_mutex before calling
      btrfs_delete_unused_bgs() because it's no longer needed after
      commit 67c5e7d464bc ("Btrfs: fix race between balance and unused block
      group deletion"). The mutex fs_info->delete_unused_bgs_mutex, the
      spinlock fs_info->unused_bgs_lock and a block group's spinlock are
      enough to get correct serialization between tasks running relocation
      and unused block group deletion (as well as between multiple tasks
      concurrently calling btrfs_delete_unused_bgs()).

      This issue was discussed (in the mailing list) during the review of
      the patch titled "btrfs: explictly delete unused block groups in
      close_ctree and ro-remount" and it was agreed that acquiring the
      cleaner mutex had to be dropped after the patch titled
      "Btrfs: fix race between balance and unused block group deletion"
      got merged (both patches were submitted at about the same time, but
      one landed in kernel 4.2 and the other in the 4.3 merge window).

      powerpc/MSI: Fix race condition in tearing down MSI interrupts

      This fixes a race which can result in the same virtual IRQ number
      being assigned to two different MSI interrupts.  The most visible
      consequence of that is usually a warning and stack trace from the
      sysfs code about an attempt to create a duplicate entry in sysfs.

      The race happens when one CPU (say CPU 0) is disposing of an MSI
      while another CPU (say CPU 1) is setting up an MSI.  CPU 0 calls
      (for example) pnv_teardown_msi_irqs(), which calls
      msi_bitmap_free_hwirqs() to indicate that the MSI (i.e. its
      hardware IRQ number) is no longer in use.  Then, before CPU 0 gets
      to calling irq_dispose_mapping() to free up the virtal IRQ number,
      CPU 1 comes in and calls msi_bitmap_alloc_hwirqs() to allocate an
      MSI, and gets the same hardware IRQ number that CPU 0 just freed.
      CPU 1 then calls irq_create_mapping() to get a virtual IRQ number,
      which sees that there is currently a mapping for that hardware IRQ
      number and returns the corresponding virtual IRQ number (which is
      the same virtual IRQ number that CPU 0 was using).  CPU 0 then
      calls irq_dispose_mapping() and frees that virtual IRQ number.
      Now, if another CPU comes along and calls irq_create_mapping(), it
      is likely to get the virtual IRQ number that was just freed,
      resulting in the same virtual IRQ number apparently being used for
      two different hardware interrupts.

      To fix this race, we just move the call to msi_bitmap_free_hwirqs()
      to after the call to irq_dispose_mapping().  Since virq_to_hw()
      doesn't work for the virtual IRQ number after irq_dispose_mapping()
      has been called, we need to call it before irq_dispose_mapping() and
      remember the result for the msi_bitmap_free_hwirqs() call.

      The pattern of calling msi_bitmap_free_hwirqs() before
      irq_dispose_mapping() appears in 5 places under arch/powerpc, and
      appears to have originated in commit 05af7bd2d75e ("[POWERPC] MPIC
      U3/U4 MSI backend") from 2007.

      ath10k: print invalid mcs reported in rx descriptor

      Sometimes hardware reports invalid mcs index in rx descriptor
      when operating in VHT80 mode and all packets with invalid mcs
      will be eventually dropped in mac80211. This issue is observerd during
      testing on QCA99X0 chipsets.

      This patch adds a warn message for dumping the rx desc info which helps
      in analysing the issue when invalid mcs is received.

      The VHT STS CAP shall be reported by firmware to host, like in case of
      QCA99x0. For QCA6174 hw family this isn't set for some reason.
      So for this particular chips, let's assume it has the ability to
      support VHT NDP in up to 4 STSs (which is true by the way).

      Change the published beamformee STS cap accordingly to 3 or to what
      the firmware reports.

      completely wrong.

      ath10k: drop probe responses when too many are queued

      In a noisy environment, when multiple interfaces are created,
      the management tx descriptors are fully occupied by the probe
      responses from all the interfaces. This prevents a new station
      from a successful association.

      Fix this by limiting the probe responses when the specified
      threshold limit is reached.

      ath10k: fix DMA alloc failure for target requested memory chunks

      During long hours of stress testing like AP interface up/down along
      with continuous ping flood from a station doing connect/disconnect,
      it is observed that the system is not able to allocate DMA consistent
      memory of size > 512KB chunks as requested by firmware in 
WMI_SERVICE_EVENTID.
      With the system memory getting fragmented during the run based on the
      size of the memory requested, the failure to return physically continguous
      memory of high order can happen. Once the system gets to this situation,
      bringing up the wifi interface will fail and a system reboot may be needed
      to make it work again. This problem is obseved with QCA99X0.

      To fix this issue, allocate the DMA memory requested by firmware during
      device probe time and keep it during the life time of the device. WMI 
service
      ready event handler is changed to allocate the memory chunks if it is
      not already allocated or if the memory allocated for the previous ready
      event is not same as the current requested ones. After this patch the
      memory usage when wifi is inactive will be inceased by few 100KB to
      3MB based on the target type.

      ath10k: fix mu-mimo rx status reporting

      MU-MIMO Rx involves different interpretation of
      the VHT-SIG-A compared to SU-MIMO.

      The incorrect interpretation led ath10k to report
      VHT MCS values greater than 9 which subsequently
      prompted mac80211 to drop such frames. This
      effectively broke Rx with MU-MIMO in many cases
      and manifested with a kernel warning in the log
      which looked like this:

      x86/headers: Convert uses of _fpstate_ia32 to _fpstate_32

      Remove uses of _fpstate_ia32 from the kernel, and move the
      legacy _fpstate_ia32 definition to the user-space only portion
      of the header.

      x86/headers: Unify 'struct _fpstate_ia32' and i386 struct _fpstate

      'struct _fpstate_ia32' and 'struct _fpstate' on i386 are
      identical in all fields, except 'padding1' being named
      'padding'.

      We unify the two structures and add a union that is both named
      'padding1' and 'padding', in the (unlikely) case there's
      user-space code that relies on the padding field name.

      We rename the two main types to be:

        struct _fpstate_32
        struct _fpstate_64

      for the 32-bit and 64-bit frame, and map them to the main and
      compat structure names (_fpstate) depending on whether we are on
      32-bit or on 64-bit kernels.

      We also keep the old _fpstate_ia32 name as a legacy name.

      Use the __u16/32/64 types we standardized on in ABI definitions
      - and which most of this header was already using.

      This will allow us to more obviously unify the compat header

      x86/headers: Fix (old) header file dependency bug in 
uapi/asm/sigcontext32.h

      Mikko Rapeli reported that the following standalone user-space
      header does not compile:

        #include <asm/sigcontext32.h>

      Due to undefined 'struct __fpx_sw_bytes' which is defined in
      asm/sigcontext.h.

      The following header order works:

        #include <asm/sigcontext.h>
        #include <asm/sigcontext32.h>

      and that's probably how everyone's been using these headers for
      the past decade or so, but it's a legit header file dependency
      bug, so include asm/sigcontext.h in sigcontext32.h to allow it
      to be built standlone.

      powerpc/pseries: Release DRC when configure_connector fails

      Commit f32393c943e2 ("powerpc/pseries: Correct cpu affinity for
      dlpar added cpus") moved dlpar_acquire_drc() call to before
      dlpar_configure_connector() call in dlpar_cpu_probe(), but missed
      to release the DRC if dlpar_configure_connector() failed.
      During CPU hotplug, if configure-connector fails for any reason,
      then this will result in subsequent CPU hotplug attempts to fail.

      Release the acquired DRC if dlpar_configure_connector() call fails
      so that the DRC is left in right isolation and allocation state
      for the subsequent hotplug operation to succeed.

      Btrfs: don't initialize a space info as full to prevent ENOSPC

      Commit 2e6e518335f8 ("Btrfs: fix block group ->space_info null pointer
      dereference") accidently marked a space info as full when initializing
      it with a value of 0 total bytes. This introduces an ENOSPC problem when
      writing file data if we mount a filesystem that has no data block groups
      allocated, because the data space info is initialized with 0 total bytes,
      marked as full, and it never gets its total bytes incremented by a
      (positive) value to unmark it as full (because there are no data block
      groups loaded when the fs is mounted).
      For metadata and system spaces this issue can never happen since we always
      have at least one metadata block group and one system block group (even
      for an empty filesystem).

      So fix this by just not initializing a space info as full, reverting the
      offending part of the commit mentioned above.

      The following test case for fstests reproduces the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$

      Instead, it supplies pause mode to do it indirectly. If driver

      ARM: 8429/1: disable GCC SRA optimization

      While working on the 32-bit ARM port of UEFI, I noticed a strange
      corruption in the kernel log. The following snprintf() statement
      (in drivers/firmware/efi/efi.c:efi_md_typeattr_format())

        snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]",

      was producing the following output in the log:

        |    |   |   |   |    |WB|WT|WC|UC]
        |    |   |   |   |    |WB|WT|WC|UC]
        |    |   |   |   |    |WB|WT|WC|UC]
        |RUN|   |   |   |    |WB|WT|WC|UC]*
        |RUN|   |   |   |    |WB|WT|WC|UC]*
        |    |   |   |   |    |WB|WT|WC|UC]
        |RUN|   |   |   |    |WB|WT|WC|UC]*
        |    |   |   |   |    |WB|WT|WC|UC]
        |RUN|   |   |   |    |   |   |   |UC]
        |RUN|   |   |   |    |   |   |   |UC]

      As it turns out, this is caused by incorrect code being emitted for
      the string() function in lib/vsprintf.c. The following code

        if (!(spec.flags & LEFT)) {
                while (len < spec.field_width--) {
                        if (buf < end)
                                *buf = ' ';
                        ++buf;
                }
        }
        for (i = 0; i < len; ++i) {
                if (buf < end)
                        *buf = *s;
                ++buf; ++s;
        }
        while (len < spec.field_width--) {
                if (buf < end)
                        *buf = ' ';
                ++buf;
        }

      when called with len == 0, triggers an issue in the GCC SRA optimization
      pass (Scalar Replacement of Aggregates), which handles promotion of signed
      struct members incorrectly. This is a known but as yet unresolved issue.
      (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular
      case, it is causing the second while loop to be executed erroneously a
      single time, causing the additional space characters to be printed.

      So disable the optimization by passing -fno-ipa-sra.

      cxl: abort cxl_pci_enable_device_hook() if PCI channel is offline

      cxl_pci_enable_device_hook() is called when attempting to enable an AFU
      sitting on a vPHB. At present, the state of the underlying CXL card's PCI
      channel is only checked when it calls cxl_afu_check_and_enable() at the
      very end, after it has already set DMA options and initialised a default
      context.

      Check the CXL card's link status before setting DMA options or 
initialising
      a default context. If the link is down, print a warning and return
      immediately.

      powerpc/powernv/pci-ioda: fix kdump with non-power-of-2 crashkernel=

      The 32-bit TCE table initialization relies on the DMA window having a
      size equal to a power of 2 (and checks for it explicitly). But
      crashkernel= has no constraint that requires a power-of-2 be specified.
      This causes the kdump kernel to fail to boot as none of the PCI devices
      (including the disk controller) are successfully initialized.

      After this change, the PCI devices successfully set up the 32-bit TCE
      table and kdump succeeds.

      powerpc/powernv/pci-ioda: fix 32-bit TCE table init in kdump kernel

      When attempting to kdump with the 4.2 kernel, we see for each PCI
      device:

       pci 0003:01     : [PE# 000] Assign DMA32 space
       pci 0003:01     : [PE# 000] Setting up 32-bit TCE table at 0..80000000

      and eventually the kdump kernel fails to boot as none of the PCI devices
      (including the disk controller) are successfully initialized.

      The EINVAL response is because the DMA window (the 2GB base window) is
      larger than the kdump kernel's reserved memory (crashkernel=, in this
      case specified to be 1024M). The check in question,

       if ((window_size > memory_hotplug_max()) || !is_power_of_2(window_size))

      is a valid sanity check for pnv_pci_ioda2_table_alloc_pages(), so adjust
      the caller to pass in a smaller window size if our maximum memory value
      is smaller than the DMA window.

      After this change, the PCI devices successfully set up the 32-bit TCE
      table and kdump succeeds.

      The problem was seen on a Firestone machine originally.

      spi: Fix documentation of spi_alloc_master()

      Actually, spi_master_put() after spi_alloc_master() must _not_ be followed
      by kfree(). The memory is already freed with the call to spi_master_put()
      through spi_master_class, which registers a release function. Calling both
      spi_master_put() and kfree() results in often nasty (and delayed) crashes
      elsewhere in the kernel, often in the networking stack.

      This reverts commit eb4af0f5349235df2e4a5057a72fc8962d00308a.

      or

      Alexey Klimov: This revert becomes valid after
      94c69f765f1b4a658d96905ec59928e3e3e07e6a when spi-imx.c
      has been fixed and there is no need to call kfree() so comment
      for spi_alloc_master() should be fixed.

      x86/vm86: Block non-root vm86(old) if mmap_min_addr != 0

      vm86 exposes an interesting attack surface against the entry
      code. Since vm86 is mostly useless anyway if mmap_min_addr != 0,
      just turn it off in that case.

      There are some reports that vbetool can work despite setting
      mmap_min_addr to zero.  This shouldn't break that use case,
      as CAP_SYS_RAWIO already overrides mmap_min_addr.

      perf probe: Link trace_probe_event into perf_probe_event

      This patch drops struct __event_package structure.  Instead, it adds a
      'struct trace_probe_event' pointer to 'struct perf_probe_event'.

      The trace_probe_event information gives further patches a chance to
      access actual probe points and actual arguments.

      Using them, 'perf probe' can get the whole list of added probes and
      print them at once.

      Other users like the upcoming bpf_loader will be able to attach one bpf
      program to different probing points of an inline function (which has
      multiple probing points) and glob functions.

      Moreover, by reading the arguments information, bpf code for reading
      those arguments can be generated.

      arm/arm64: KVM: vgic: Move active state handling to flush_hwstate

      We currently set the physical active state only when we *inject* a new
      pending virtual interrupt, but this is actually not correct, because we
      could have been preempted and run something else on the system that
      resets the active state to clear.  This causes us to run the VM with the
      timer set to fire, but without setting the physical active state.

      The solution is to always check the LR configurations, and we if have a
      mapped interrupt in the LR in either the pending or active state
      (virtual), then set the physical active state.

      perf intel-pt: Add support for PERF_RECORD_SWITCH

      Add support for selecting and processing PERF_RECORD_SWITCH events for
      use by Intel PT.  If they are available, they will be used in preference
      to sched_switch events.

      This enables an unprivileged user to trace multi-threaded or
      multi-process workloads with any level of perf_event_paranoid.  However
      it depends on kernel support for PERF_RECORD_SWITCH.

      Without this patch, tracing a multi-threaded workload will decode
      without error but all the data will be attributed to the main thread.

      Without this patch, tracing a multi-process workload will result in
      decoder errors because the decoder will not know which executable is
      executing.

      x86/insn: perf tools: Pedantically tweak opcode map for MPX instructions

      The MPX instructions are presently not described in the SDM
      opcode maps, and there are not encoding characters for bnd
      registers, address method or operand type.  So the kernel
      opcode map is using 'Gv' for bnd registers and 'Ev' for
      everything else.  That is fine because the instruction
      decoder does not use that information anyway, except as
      an indication that there is a ModR/M byte.

      Nevertheless, in some cases the 'Gv' and 'Ev' are the wrong
      way around, BNDLDX and BNDSTX have 2 operands not 3, and it
      wouldn't hurt to identify the mandatory prefixes.

      This has no effect on the decoding of valid instructions,
      but the addition of the mandatory prefixes will cause some
      invalid instructions to error out that wouldn't have
      previously.

      Note that perf tools has a copy of the instruction decoder
      and provides a test for new instructions which includes MPX
      instructions e.g.

        $ perf test "x86 ins"
        39: Test x86 instruction decoder - new instructions          : Ok

      Or to see the details:

        $ perf test -v "x86 ins"

      Commiter notes:

      And to see these MPX instructions specifically:

        $ perf test -v "x86 ins" 2>&1 | grep bndldx | head -3
        Decoded ok: 0f 1a 00                    bndldx (%eax),%bnd0
        Decoded ok: 0f 1a 05 78 56 34 12        bndldx 0x12345678,%bnd0

      perf tools: Add a test for decoding of new x86 instructions

      Add a new test titled:

        Test x86 instruction decoder - new instructions

      The purpose of this test is to check the instruction decoder after new
      instructions have been added.  Initially, MPX instructions are tested
      which are already supported, but the definitions in x86-opcode-map.txt
      will be tweaked in a subsequent patch, after which this test can be run
      to verify those changes.

      The data for the test comes from assembly language instructions in
      insn-x86-dat-src.c which is converted into bytes by the scripts
      gen-insn-x86-dat.sh and gen-insn-x86-dat.awk, and included into the test
      program insn-x86.c as insn-x86-dat-32.c and insn-x86-dat-64.c.

      The conversion is not done as part of the perf tools build because the
      test data must be under (git) change control in order for the test to be
      repeatably-correct.  Also it may require a recent version of binutils.

      perf tools: Display build warning if x86 instruction decoder differs from 
kernel

      perf tools has a copy of the x86 instruction decoder used by the kernel.
      The expectation is that the copy will be kept more-or-less in-synch with
      the kernel version.  Consequently it is helpful to know if there are
      differences.

      This patch adds a check into the perf tools build so that a diff is done
      on the sources, and a warning is printed if they are different.  Note
      that the warning is not fatal and the build continues as normal.

      The check is done as part of building the instruction decoder, so, like
      a compiler warning, it is not seen unless the instruction decoder has to
      be re-compiled. e.g.

        $ make -C tools/perf >/dev/null
        $ echo "/* blah */" >> tools/perf/util/intel-pt-decoder/inat_types.h
        $ make -C tools/perf >/dev/null
        Warning: Intel PT: x86 instruction decoder differs from kernel
        $ make -C tools/perf >/dev/null

      Merge tag 'perf-urgent-for-mingo' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

      Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

        - In some cases where perf_event.fork.{pid,tid} should be used we were 
instead
          using perf_event.comm.{pid,tid}, which is not a problem for for the 
'pid'
          case, that sits in the same place in these union_perf_event members, 
but
          comm.tid sits where fork.ppid is, oops.

          These cases were considered as (potentially) problematic:

           - 'perf script' with !sample_id_all, i.e. only non old kernels 
without
              perf_event_attr.sample_id_all.

           - intel_pt could be affected when decoding without timestamps, as 
the exit
             event is only used to flush out data which anyway gets flushed at 
the
             end of the session.

           - intel_bts also uses the exit event to flush data which would 
probably not
             cause errors as it would get flushed at the end of the session 
instead.

          Fix it. (Adrian Hunter)

        - Due to relaxing the compiler checks for bison generated files, we 
missed
          updating one parse_events_add_pmu() caller when this function had its
          prototype changed, fix it. (Jiri Olsa)

      ipv6: Fix IPsec pre-encap fragmentation check

      The IPv6 IPsec pre-encap path performs fragmentation for tunnel-mode
      packets.  That is, we perform fragmentation pre-encap rather than
      post-encap.

      A check was added later to ensure that proper MTU information is
      passed back for locally generated traffic.  Unfortunately this
      check was performed on all IPsec packets, including transport-mode
      packets.

      What's more, the check failed to take GSO into account.

      The end result is that transport-mode GSO packets get dropped at
      the check.

      This patch fixes it by moving the tunnel mode check forward as well
      as adding the GSO check.

      optimize_nops() is buggy in two aspects:

      perf tools: Fix use of wrong event when processing exit events

      In a couple of cases the 'comm' member of 'union event' has been used
      instead of the correct member ('fork') when processing exit events.

      In the cases where it has been used incorrectly, only the 'pid' and
      'tid' are affected.  The 'pid' value would be correct anyway because it
      is in the same position in 'comm' and 'fork' events, but the 'tid' would
      have been incorrectly assigned from 'ppid'.

      However, for exit events, the kernel puts the current task in the 'ppid'
      and 'ttid' which is the same as the exiting task.  That is 'ppid' ==
      'pid' and if the task is not multi-threaded, 'pid' == 'tid' i.e. the
      data goes wrong only when tracing multi-threaded programs.

      It is hard to find an example of how this would produce an error in
      practice.  There are 3 occurences of the fix:

      1. perf script is only affected if !sample_id_all which only happens on
        old kernels.

      2. intel_pt is only affected when decoding without timestamps
         and would probably still decode correctly - the exit event is
         only used to flush out data which anyway gets flushed at the
         end of the session

      3. intel_bts also uses the exit event to flush data which
         would probably not cause errors as it would get flushed at
         the end of the session instead

      The changes modifies the CPU_TOPOLOGY section, making sure it is
      backward/forward compatible.

      The patch checks the section size before reading the core and socket ids.

      It never reads data crossing the section boundary.  An old perf binary
      without this patch can also correctly read the perf.data from a new perf
      with this patch.

      Because the new info is added at the end of the cpu_topology section, an
      old perf tool ignores the extra data.

      Examples:

      1. New perf with this patch read perf.data from an old perf without the
         patch:

        $ perf_new report -i perf_old.data --header-only -I
        ......
        # sibling threads : 33
        # sibling threads : 34
        # sibling threads : 35
        # Core ID and Socket ID information is not available
        # node0 meminfo  : total = 32823872 kB, free = 29315548 kB
        # node0 cpu list : 0-17,36-53
        ......

      2. Old perf without the patch reads perf.data from a new perf with the
         patch:

        $ perf_old report -i perf_new.data --header-only -I
        ......
        # sibling threads : 33
        # sibling threads : 34
        # sibling threads : 35
        # node0 meminfo  : total = 32823872 kB, free = 29190932 kB
        # node0 cpu list : 0-17,36-53
        ......

      3. New perf read new perf.data:

        $ perf_new report -i perf_new.data --header-only -I
        ......
        # sibling threads : 33
        # sibling threads : 34
        # sibling threads : 35
        # CPU 0: Core ID 0, Socket ID 0
        # CPU 1: Core ID 1, Socket ID 0
        ......
        # CPU 61: Core ID 10, Socket ID 1
        # CPU 62: Core ID 11, Socket ID 1
        # CPU 63: Core ID 16, Socket ID 1
        # node0 meminfo  : total = 32823872 kB, free = 29190932 kB
        # node0 cpu list : 0-17,36-53

      perf tools: Copy linux/filter.h to tools/include

      This patch copies filter.h from include/linux/kernel.h to
      tools/include/linux/filter.h to enable other libraries to use macros in 
it,
      like libbpf which will be introduced by further patches.

      Currently, the filter.h copy only contains the useful macros needed by
      libbpf for not introducing too much dependence.

      tools/perf/MANIFEST is also updated for 'make perf-*-src-pkg'.

      One change:
        The 'imm' field of BPF_EMIT_CALL becomes ((FUNC) - BPF_FUNC_unspec) to
        suit user space code generator.

      perf tools: Always use non inlined file name for 'srcfile' sort key

      When profiling the kernel with the 'srcfile' sort key it's common to
      "get stuck" in include. For example a lot of code uses current or other
      inlines, so they get accounted to some random include file. This is not
      very useful as a high level categorization.

      For example just profiling the idle loop usually shows mostly inlines,
      so you never see the actual cpuidle file.

      This patch changes the 'srcfile' sort key to always unwind the inline
      stack using BFD/DWARF. So we always account to the base function that
      called the inline.

      In a few cases include is still shown (for example for MSR accesses),
      but that is because they get inlining expanded as part of assigning to a
      global function pointer. For the majority it works fine though.

      v2: Use simpler while loop. Add maximum iteration count.

      spi: spi-pxa2xx: Check status register to determine if SSSR_TINT is 
disabled

      On Intel Baytrail, there is case when interrupt handler get called, no SPI
      message is captured. The RX FIFO is indeed empty when RX timeout pending
      interrupt (SSSR_TINT) happens.

      Use the BIOS version where both HSUART and SPI are on the same IRQ. Both
      drivers are using IRQF_SHARED when calling the request_irq function. When
      running two separate and independent SPI and HSUART application that
      generate data traffic on both components, user will see messages like
      below on the console:

        pxa2xx-spi pxa2xx-spi.0: bad message state in interrupt handler

      This commit will fix this by first checking Receiver Time-out Interrupt,
      if it is disabled, ignore the request and return without servicing.

      nohz: Assert existing housekeepers when nohz full enabled

      The code ensures that when nohz full is running, at least the
      boot CPU serves as a housekeeper and it can't be later offlined.

      Let's assert this assumption to make sure that we have CPUs to
      handle unbound jobs like workqueues and timers while nohz full
      CPUs run undisturbed.

      Also improve the comments on housekeeper offlining prevention.

      The problem addressed in this patch is about affining unpinned

      by unnecessary jitter due to firing of such timers on them.

      This patch will affine timers to online CPUs which are not full
      dynticks in NOHZ_FULL configured systems. It should not
      introduce overhead in nohz full off case due to static keys.

      x86/mm/srat: Print non-volatile flag in SRAT

      With the addition of NVDIMM support, a question came up as to
      whether NVDIMM ranges should be in the SRAT with this bit set.
      I think the consensus was no because the ranges are in the NFIT
      with proximity domain information there.

      ACPI is not clear on the meaning of this bit in the SRAT.
      If someone is setting it, we might want to ask them what they
      expect to happen with it.

      Right now this bit is only printed if all the ACPI debug
      information is turned on.

      Let's just WARN instead, this will provide helpful information

      ARM: OMAP2+: omap-device: fix race deferred probe of omap_hsmmc vs

      Kernel fails to boot 50% of times (form build to build) with
      RT-patchset applied due to the following race - on late boot
      stages deferred_probe_work_func->omap_hsmmc_probe races with 
omap_device_late_ini.

      The same issue has been reported now on linux-next (4.3) by Keerthy [1]

      late_initcall
       - deferred_probe_initcal() tries to re-probe all pending driver's probe.

      The issue happens because omap_device_late_init() do not take into
      account that some drivers are present, but their probes were not
      finished successfully and where deferred instead. This is the valid
      case, and omap_device_late_init() should not idle such devices.

      To fix this issue, the value of omap_device->_driver_status field
      should be checked not only for BUS_NOTIFY_BOUND_DRIVER (driver is
      present and has been bound to device successfully), but also checked
      for BUS_NOTIFY_BIND_DRIVER (driver about to be bound) - which means
      driver is present and there was try to bind it to device.

      There's obviously no reason to write a NUL-terminating byte into
      the debugfs file. Apparently nobody tried to use this from a tool
      that doesn't strip NUL bytes though, so we never noticed. Fix it.

      iwlwifi: mvm: make sure d0i3 exit work runs before suspending

      If we are in d0i3 when entering suspend, we leave d0i3 so that
      mac80211 can call us to remove connections or whatever before going to
      suspend.  We do this by calling pm_runtime_resume() early in the slave
      transport flow and reactivating it later, when the wiphy suspend flow
      runs.

      The problem is that we queue a work in order to leave d0i3.  If this
      work hasn't run yet when the wiphy suspend flow is called, we have a
      race and entering d0i3 fails (because we're still holding the
      IWL_MVM_REF_EXIT_WORK reference).

      To solve this, simply flush the d0i3_exit_work at the beginning of the
      iwl_mvm_suspend() function.

      iwlwifi: mvm: don't ask for beacons when AP vif and no assoc sta

      When in AP mode, we need beacons from other APs for HT protection.
      However, when there's no any associated station we will not do
      any Tx and thus don't really need beacons. On the other hand, these
      beacons will cause a lot of unnecessary wakeups which increase our
      power consumption. Handle this by asking FW to pass beacons only when
      there's at least one associated station.

      Laura Abbott <labbott@xxxxxxxxxx> produced a patch which lead us to
      inspect symbol_put_addr(). This function has a comment claiming it
      doesn't need to disable preemption around the module lookup
      because it holds a reference to the module it wants to find, which
      therefore cannot go away.

      This is wrong (and a false optimization too, preempt_disable() is really
      rather cheap, and I doubt any of this is on uber critical paths,
      otherwise it would've retained a pointer to the actual module anyway and
      avoided the second lookup).

      While its true that the module cannot go away while we hold a reference
      on it, the data structure we do the lookup in very much _CAN_ change
      while we do the lookup. Therefore fix the comment and add the
      required preempt_disable().

      Each of those EFI memory types is mapped to a corresponding

      MT_NORMAL_WT is defined, and its encoding is added to MAIR_EL1
      when initializing the CPU.

      acpi, x86: Implement arch_apei_get_mem_attributes()

      ... to allow an arch specific implementation of getting page
      protection type associated with a physical address.

      On x86, we currently have no way to look up the EFI memory map
      attributes for a region in a consistent way, because the
      memmap is discarded after efi_free_boot_services(). So if
      you call efi_mem_attributes() during boot and at runtime,
      you could theoretically see different attributes.

      Since we are yet to see any x86 platforms that require
      anything other than PAGE_KERNEL (some arm64 platforms
      require the equivalent of PAGE_KERNEL_NOCACHE), return that
      until we know differently.

      efi, x86: Rearrange efi_mem_attributes()

      x86 and ia64 implement efi_mem_attributes() differently. This
      function needs to be available for other architectures
      (such as arm64) as well, such as for the purpose of ACPI/APEI.

      ia64 EFI does not set up a 'memmap' variable and does not set
      the EFI_MEMMAP flag, so it needs to have its unique implementation
      of efi_mem_attributes().

      Move efi_mem_attributes() implementation from x86 to the core
      EFI code, and declare it with __weak.

      It is recommended that other architectures should not override
      the default implementation.

      This reverts commit:

        aeffc4928ea2 ("x86/efi: Request desired alignment via the PE/COFF 
headers")

      Linn reports that Signtool complains that kernels built with
      CONFIG_EFI_STUB=y are violating the PE/COFF specification because
      the 'SizeOfImage' field is not a multiple of 'SectionAlignment'.

      This violation was introduced as an optimisation to skip having
      the kernel relocate itself during boot and instead have the
      firmware place it at a correctly aligned address.

      No one else has complained and I'm not aware of any firmware
      implementations that refuse to boot with commit aeffc4928ea2,
      but it's a real bug, so revert the offending commit.

      x86/efi-bgrt: Switch pr_err() to pr_debug() for invalid BGRT

      It's totally legitimate, per the ACPI spec, for the firmware to
      set the BGRT 'status' field to zero to indicate that the BGRT
      image isn't being displayed, and we shouldn't be printing an
      error message in that case because it's just noise for users. So
      swap pr_err() for pr_debug().

      However, Josh points that out it still makes sense to test the
      validity of the upper 7 bits of the 'status' field, since
      they're marked as "reserved" in the spec and must be zero. If
      firmware violates this it really *is* an error.

      iommu/iova: Avoid over-allocating when size-aligned

      Currently, allocating a size-aligned IOVA region quietly adjusts the
      actual allocation size in the process, returning a rounded-up
      power-of-two-sized allocation. This results in mismatched behaviour in
      the IOMMU driver if the original size was not a power of two, where the
      original size is mapped, but the rounded-up IOVA size is unmapped.

      Whilst some IOMMUs will happily unmap already-unmapped pages, others
      consider this an error, so fix it by computing the necessary alignment
      padding without altering the actual allocation size. Also clean up by
      making pad_size unsigned, since its callers always pass unsigned values
      and negative padding makes little sense here anyway.
