Pull x86/mm changes from Ingo Molnar:
 "The biggest change is new TLB partial flushing code for AMD CPUs.
  (The v3.6 kernel had the Intel CPU side code, see commits
  e0ba94f14f74..effee4b9b3b.)

  There's also various other refinements around the TLB flush code"

* 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86: Distinguish TLB shootdown interrupts from other functions call interrupts
  x86/mm: Fix range check in tlbflush debugfs interface
  x86, cpu: Preset default tlb_flushall_shift on AMD
  x86, cpu: Add AMD TLB size detection
  x86, cpu: Push TLB detection CPUID check down
  x86, cpu: Fixup tlb_flushall_shift formatting
