Pull misc x86 cleanups from Ingo Molnar:
 "The following commit deserves special mention:

   22dc02f81c Revert "sched/fair: Move unused stub functions to header"

  This is in x86/cleanups, because the revert is a re-application of a
  number of cleanups that got removed inadvertedly"

[ This also effectively undoes the amd_check_microcode() microcode
  declaration change I had done in my microcode loader merge in commit
  42a7f6e3ff ("Merge tag 'x86_microcode_for_v6.6_rc1' [...]").

  I picked the declaration change by Arnd from this branch instead,
  which put it in <asm/processor.h> instead of <asm/microcode.h> like I
  had done in my merge resolution   - Linus ]
