#     Pull x86 fixes from Thomas Gleixner:
#      "A set of fixes for X86:
#     
#        - Ensure that the PIT is set up when the local APIC is disable or
#          configured in legacy mode. This is caused by an ordering issue
#          introduced in the recent changes which skip PIT initialization when
#          the TSC and APIC frequencies are already known.
#     
#        - Handle malformed SRAT tables during early ACPI parsing which caused
#          an infinite loop anda boot hang.
#     
#        - Fix a long standing race in the affinity setting code which affects
#          PCI devices with non-maskable MSI interrupts. The problem is caused
#          by the non-atomic writes of the MSI address (destination APIC id)
#          and data (vector) fields which the device uses to construct the MSI
#          message. The non-atomic writes are mandated by PCI.
#     
#          If both fields change and the device raises an interrupt after
#          writing address and before writing data, then the MSI block
#          constructs a inconsistent message which causes interrupts to be
#          lost and subsequent malfunction of the device.
#     
#          The fix is to redirect the interrupt to the new vector on the
#          current CPU first and then switch it over to the new target CPU.
#          This allows to observe an eventually raised interrupt in the
#          transitional stage (old CPU, new vector) to be observed in the APIC
#          IRR and retriggered on the new target CPU and the new vector.
#     
#          The potential spurious interrupts caused by this are harmless and
#          can in the worst case expose a buggy driver (all handlers have to
#          be able to deal with spurious interrupts as they can and do happen
#          for various reasons).
#     
#        - Add the missing suspend/resume mechanism for the HYPERV hypercall
#          page which prevents resume hibernation on HYPERV guests. This
#          change got lost before the merge window.
#     
#        - Mask the IOAPIC before disabling the local APIC to prevent
#          potentially stale IOAPIC remote IRR bits which cause stale
#          interrupt lines after resume"
