Merge branch 'x86-process-for-linus' of git://git.kernel.org/pub/scm/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"
