Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 build-armhf-xsm               4 host-build-prep          fail REGR. vs. 109165

Tests which are failing intermittently (not blocking):

fail in 109211 pass in 109229

commit baf2950213e6a50801940643e2549a5baa21ad71

    xen/arm: Survive unknown traps from guests
    
    Currently we crash Xen if we see an ESR_EL2.EC value we don't recognise.
    As configurable disables/enables are added to the architecture
    (controlled by RES1/RESO bits respectively), with associated synchronous
    exceptions, it may be possible for a guest to trigger exceptions with
    classes that we don't recognise.
    
    While we can't service these exceptions in a manner useful to the guest,
    we can avoid bringing down the host. Per ARM DDI 0487A.k_iss10775, page
    D7-1937, EC values within the range 0x00 - 0x2c are reserved for future
    use with synchronous exceptions, and EC within the range 0x2d - 0x3f may
    be used for either synchronous or asynchronous exceptions.
    
    The patch makes Xen handle any unknown EC by injecting an UNDEFINED
    exception into the guest, with a corresponding (ratelimited) warning in
    the log.
    
    This patch is based on Linux commit f050fe7a9164 "arm: KVM: Survive unknown
    traps from the guest".

    xen/arm: do_trap_hypervisor: Separate hypervisor and guest traps
    
    The function do_trap_hypervisor is currently handling both trap coming
    from the hypervisor and the guest. This makes difficult to get specific
    behavior when a trap is coming from either the guest or the hypervisor.
    
    Split the function into two parts:
        - do_trap_guest_sync to handle guest traps
        - do_trap_hyp_sync to handle hypervisor traps
    
    On AArch32, the Hyp Trap Exception provides the standard mechanism for
    trapping Guest OS functions to the hypervisor (see B1.14.1 in ARM DDI
    0406C.c). It cannot be generated when generated when the processor is in
    Hyp Mode, instead other exception will be used. So it is fine to replace
    the call to do_trap_hypervisor by do_trap_guest_sync.
    
    For AArch64, there are two distincts exception depending whether the
    exception was taken from the current level (hypervisor) or lower level
    (guest).
    
    Note that the unknown traps from guests will lead to panic Xen. This is
    already behavior and is left unchanged for simplicy. A follow-up patch
    will address that.

    libxl: u.hvm.usbdevice_list is checked for emptiness
    
    Currently usbdevice_list is only checked for nullity. But the OCaml
    binding will convert empty list to a pointer to NULL, instead of a
    NULL pointer. That means the OCaml binding will fail to disable USB.
    
    This patch will check emptiness of usbdevice_list. And NULL is still a
    valid empty list.

    x86: correct boot time page table setup
    
    While using alloc_domheap_pages() and assuming the allocated memory is
    directly accessible is okay at boot time (as we run on the idle page
    tables there), memory hotplug code too assumes it can access the
    resulting page tables without using map_domain_page() or alike, and
    hence we need to obtain memory suitable for ordinary page table use
    here.

    x86: correct create_bounce_frame
    
    Commit d9b7ef209a7 ("x86: drop failsafe callback invocation from
    assembly") didn't go quite far enough with the cleanup it did: The
    changed maximum frame size should also have been reflected in the early
    address range check (which has now been pointed out to have been wrong
    anyway, using 60 instead of 0x60), and it should have updated the
    comment ahead of the function.
    
    Also adjust the lower bound - all is fine (for our purposes) if the
    initial guest kernel stack pointer points right at the hypervisor base
    address, as only memory _below_ that address is going to be written.
    
    Additionally limit the number of times %rsi is being adjusted to what
    is really needed.
    
    Finally move exception fixup code into the designated .fixup section
    and macroize the stores to guest stack.

    x86/vm_event: fix race between __context_switch() and vm_event_resume()
    
    The introspection agent can reply to a vm_event faster than
    vmx_vmexit_handler() can complete in some cases, where it is then
    not safe for vm_event_set_registers() to modify v->arch.user_regs.
    In the test scenario, we were stepping over an INT3 breakpoint by
    setting RIP += 1. The quick reply tended to complete before the VCPU
    triggering the introspection event had properly paused and been
    descheduled. If the reply occurs before __context_switch() happens,
    __context_switch() clobbers the reply by overwriting
    v->arch.user_regs from the stack. If we don't pass through
    __context_switch() (due to switching to the idle vCPU), reply data
    wouldn't be picked up when switching back straight to the original
    vCPU.
    
    This patch ensures that vm_event_resume() code only sets per-VCPU
    data to be used for the actual setting of registers later in
    hvm_do_resume() (similar to the model used to control setting of CRs
    and MSRs).
    
    The patch additionally removes the sync_vcpu_execstate(v) call from
    vm_event_resume(), which is no longer necessary, which removes the
    associated broadcast TLB flush (read: performance improvement).

    x86/vpmu_intel: fix hypervisor crash by masking PC bit in MSR_P6_EVNTSEL
    
    Setting Pin Control (PC) bit (19) in MSR_P6_EVNTSEL results in a General
    Protection Fault and thus results in a hypervisor crash. This behavior has
    been observed on two generations of Intel processors namely, Haswell and
    Broadwell. Other Intel processor generations were not tested. However, it
    does seem to be a possible erratum that hasn't yet been confirmed by Intel.
    
    To fix the problem this patch masks PC bit and returns an error in
    case any guest tries to write to it on any Intel processor. In addition
    to the fact that setting this bit crashes the hypervisor on Haswell and
    Broadwell, the PC flag bit toggles a hardware pin on the physical CPU
    every time the programmed event occurs and the hardware behavior in
    response to the toggle is undefined in the SDM, which makes this bit
    unsafe to be used by guests and hence should be masked on all machines.
