#     Pull x86 fixes from Thomas Gleixner:
#      "Three interrupt related fixes for X86:
#     
#        - Move disabling of the local APIC after invoking fixup_irqs() to
#          ensure that interrupts which are incoming are noted in the IRR and
#          not ignored.
#     
#        - Unbreak affinity setting.
#     
#          The rework of the entry code reused the regular exception entry
#          code for device interrupts. The vector number is pushed into the
#          errorcode slot on the stack which is then lifted into an argument
#          and set to -1 because that's regs->orig_ax which is used in quite
#          some places to check whether the entry came from a syscall.
#     
#          But it was overlooked that orig_ax is used in the affinity cleanup
#          code to validate whether the interrupt has arrived on the new
#          target. It turned out that this vector check is pointless because
#          interrupts are never moved from one vector to another on the same
#          CPU. That check is a historical leftover from the time where x86
#          supported multi-CPU affinities, but not longer needed with the now
#          strict single CPU affinity. Famous last words ...
#     
#        - Add a missing check for an empty cpumask into the matrix allocator.
#     
#          The affinity change added a warning to catch the case where an
#          interrupt is moved on the same CPU to a different vector. This
#          triggers because a condition with an empty cpumask returns an
#          assignment from the allocator as the allocator uses for_each_cpu()
#          without checking the cpumask for being empty. The historical
#          inconsistent for_each_cpu() behaviour of ignoring the cpumask and
#          unconditionally claiming that CPU0 is in the mask struck again.
#          Sigh.
#     
#       plus a new entry into the MAINTAINER file for the HPE/UV platform"
