Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner: "Another pile of small fixes and updates for x86: - Plug a hole in the SMAP implementation which misses to clear AC on NMI entry - Fix the norandmaps/ADDR_NO_RANDOMIZE logic so the command line parameter works correctly again - Use the proper accessor in the startup64 code for next_early_pgt to prevent accessing of invalid addresses and faulting in the early boot code. - Prevent CPU hotplug lock recursion in the MTRR code - Unbreak CPU0 hotplugging - Rename overly long CPUID bits which got introduced in this cycle - Two commits which mark data 'const' and restrict the scope of data and functions to file scope by making them 'static'" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86: Constify attribute_group structures x86/boot/64/clang: Use fixup_pointer() to access 'next_early_pgt' x86/elf: Remove the unnecessary ADDR_NO_RANDOMIZE checks x86: Fix norandmaps/ADDR_NO_RANDOMIZE x86/mtrr: Prevent CPU hotplug lock recursion x86: Mark various structures and functions as 'static' x86/cpufeature, kvm/svm: Rename (shorten) the new "virtualized VMSAVE/VMLOAD" CPUID flag x86/smpboot: Unbreak CPU0 hotplug x86/asm/64: Clear AC on NMI entries
