      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"

      Pull x86 pti fixes from Thomas Gleixner:
       "A set of updates for the x86/pti related code:
      
         - Preserve r8-r11 in int $0x80. r8-r11 need to be preserved, but the
           int$80 entry code removed that quite some time ago. Make it correct
           again.
      
         - A set of fixes for the Global Bit work which went into 4.17 and
           caused a bunch of interesting regressions:
      
            - Triggering a BUG in the page attribute code due to a missing
              check for early boot stage
      
            - Warnings in the page attribute code about holes in the kernel
              text mapping which are caused by the freeing of the init code.
              Handle such holes gracefully.
      
            - Reduce the amount of kernel memory which is set global to the
              actual text and do not incidentally overlap with data.
      
            - Disable the global bit when RANDSTRUCT is enabled as it
              partially defeats the hardening.
      
            - Make the page protection setup correct for vma->page_prot
              population again. The adjustment of the protections fell through
              the crack during the Global bit rework and triggers warnings on
              machines which do not support certain features, e.g. NX"
