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"
