Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-i386-xl-qemuu-winxpsp3 15 guest-localmigrate.2 fail REGR. vs. 62168

Regressions which are regarded as allowable (not blocking):
 test-armhf-armhf-libvirt-vhd  3 host-install(3)         broken REGR. vs. 62168

    xen/arm: vgic-v2: Map the GIC virtual CPU interface with the correct size
    
    On GICv2, the GIC virtual CPU interface is at minimum 8KB. Due some to
    some necessary quirk for GIC using 64KB stride, we are mapping the
    region in 2 time.
    The first mapping is 4KB and the second one is 8KB, i.e 12KB in total.
    Although the minimum supported size (and widely used) is 8KB. This means
    that we are mapping 4KB more to any guest using GICv2.
    
    While this looks scary at first glance, the GIC virtual CPU interface is
    most frequently at the end the GIC I/O region. So we will most likely
    map an an unused I/O region or a mirrored version of GICV for platform
    using 64KB stride.
    
    Nonetheless, fix the second mapping to only map 4KB.

    xen/arm: vgic: Correctly emulate write when byte is used
    
    When a guest is writing a byte, the value will be located in bits[7:0]
    of the register.
    
    Although the current implementation is expecting the byte at the Nth
    byte of the register where N = address & 4;
    
    When the address is not 4-byte aligned, the corresponding byte in the
    internal state will always be set to zero rather.
    
    Note that byte access are only used for GICD_IPRIORITYR and
    GICD_ITARGETSR. So the worst things that could happen is not setting the
    priority correctly and ignore the target vCPU written.

    xen: arm: bootfdt: Avoid reading off the front of *_cells array
    
    In device_tree_for_each_node the call to the callback was using
    {address,size}_cells[depth - 1], which at depth 0 could read off the
    front of the array.
    
    We already handled this correctly in the rest of the loop so fixup
    this instance as well.

    xen: arm: handle accesses to CNTP_CVAL_EL0
    
    All OSes we have run on top of Xen use CNTP_TVAL_EL0 but for
    completeness we really should handle CVAL too.
    
    In vtimer_emulate_cp64 pull the propagation of the 64-bit result into
    two 32-bit registers out of the switch to avoid duplicating for every
    register. We also need to initialise x now since previously the only
    register implemented register was R/O.
    
    While adding HSR_SYSREG_CNTP_CVAL_EL0 also move
    HSR_SYSREG_CNTP_CTL_EL0 so it is sorted correctly.

    xen: arm: correctly handle vtimer traps from userspace
    
    Previously 32-bit userspace on 32-bit kernel and 64-bit userspace on
    64-bit kernel could access these registers irrespective of whether the
    kernel had configured them to be allowed to. To fix this:
    
     - Userspace access to CNTP_CTL_EL0 and CNTP_TVAL_EL0 should be gated
       on CNTKCTL_EL1.EL0PTEN.
     - Userspace access to CNTPCT_EL0 should be gated on
       CNTKCTL_EL1.EL0PCTEN.
    
    When we do not handle an access we now silently inject an undef even
    in debug mode since the debugging messages are not helpful (we have
    handled the access, by explicitly choosing not to).
    
    The usermode accessibility check is rather repetitive, so a helper
    macro is introduced.
    
    Since HSR_EC_CP15_64 cannot be taken from a guest in AArch64 mode
    except due to a hardware bug switch the associated check to a BUG_ON
    (which will be switched to something more appropriate in a subsequent
    patch)
    
    Fix a coding style issue in HSR_CPREG64(CNTPCT) while touching similar
    code.

    x86/sysctl: don't clobber memory if NCAPINTS > ARRAY_SIZE(pi->hw_cap)
    
    There is no current problem, as both NCAPINTS and pi->hw_cap are 8 entries,
    but the limit should be calculated appropriately so as to avoid hypervisor
    stack corruption if the two do get out of sync.

    x86/hvm: fix saved pmtimer and hpet values
    
    The ACPI PM timer is sometimes broken on live migration.
    Since vcpu->arch.hvm_vcpu.guest_time is always zero in other than
    "delay for missed ticks mode". Even in "delay for missed ticks mode",
    vcpu's guest_time field is not valid (i.e. zero) when
    the state of vcpu is "blocked". (see pt_save_timer function)
    
    The original author (Tim Deegan) of pmtimer_save() must have intended
    that it saves the last scheduled time of the vcpu. Unfortunately it was
    already implied this bug. FYI, there is no other timer mode than
    "delay for missed ticks mode" then.
    
    For consistency with HPET, pmtimer_save() should refer hvm_get_guest_time()
    to update the counter as well as hpet_save() does.
    
    Without this patch, the clock of windows server 2012R2 without HPET
    might leap forward several minutes on live migration.
