Merge branch 'x86-process-for-linus' of git://git./linux/kernel/git/tip/tip

Pul x86/process updates from Ingo Molnar:
 "The main change in this cycle was to add the ARCH_[GET|SET]_CPUID
  prctl() ABI extension to control the availability of the CPUID
  instruction, analogously to the existing PR_GET|SET_TSC ABI that
  controls RDTSC.

  Motivation: the 'rr' user-space record-and-replay execution debugger
  would like to trap and emulate the CPUID instruction - which
  instruction is normally unprivileged.

  Trapping CPUID is possible on IvyBridge and later Intel CPUs - expose
  this hardware capability"
