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" * 'x86-process-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/syscalls/32: Ignore arch_prctl for other architectures um/arch_prctl: Fix fallout from x86 arch_prctl() rework x86/arch_prctl: Add ARCH_[GET|SET]_CPUID x86/cpufeature: Detect CPUID faulting support x86/syscalls/32: Wire up arch_prctl on x86-32 x86/arch_prctl: Add do_arch_prctl_common() x86/arch_prctl/64: Rename do_arch_prctl() to do_arch_prctl_64() x86/arch_prctl/64: Use SYSCALL_DEFINE2 to define sys_arch_prctl() x86/arch_prctl: Rename 'code' argument to 'option' x86/msr: Rename MISC_FEATURE_ENABLES to MISC_FEATURES_ENABLES x86/process: Optimize TIF_NOTSC switch x86/process: Correct and optimize TIF_BLOCKSTEP switch x86/process: Optimize TIF checks in __switch_to_xtra()
