#     Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Thomas Gleixner:
#      "Another set of x86 related updates:
#     
#        - Fix the long broken x32 version of the IPC user space headers which
#          was noticed by Arnd Bergman in course of his ongoing y2038 work.
#          GLIBC seems to have non broken private copies of these headers so
#          this went unnoticed.
#     
#        - Two microcode fixlets which address some more fallout from the
#          recent modifications in that area:
#     
#           - Unconditionally save the microcode patch, which was only saved
#             when CPU_HOTPLUG was enabled causing failures in the late
#             loading mechanism
#     
#           - Make the later loader synchronization finally work under all
#             circumstances. It was exiting early and causing timeout failures
#             due to a missing synchronization point.
#     
#        - Do not use mwait_play_dead() on AMD systems to prevent excessive
#          power consumption as the CPU cannot go into deep power states from
#          there.
#     
#        - Address an annoying sparse warning due to lost type qualifiers of
#          the vmemmap and vmalloc base address constants.
#     
#        - Prevent reserving crash kernel region on Xen PV as this leads to
#          the wrong perception that crash kernels actually work there which
#          is not the case. Xen PV has its own crash mechanism handled by the
#          hypervisor.
#     
#        - Add missing TLB cpuid values to the table to make the printout on
#          certain machines correct.
#     
#        - Enumerate the new CLDEMOTE instruction
#     
#        - Fix an incorrect SPDX identifier
#     
#        - Remove stale macros"
