Merge branch 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86/asm changes from Ingo Molnar: "The biggest change (by line count) is the unification of the XOR code and then the introduction of an additional SSE based XOR assembly method. The other bigger change is the head_32.S rework/cleanup by Borislav Petkov. Last but not least there's the usual laundry list of small but dangerous (and hopefully perfectly tested) changes to subtle low level x86 code, plus cleanups." * 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, head_32: Give the 6 label a real name x86, head_32: Remove second CPUID detection from default_entry x86: Detect CPUID support early at boot x86, head_32: Remove i386 pieces x86: Require MOVBE feature in cpuid when we use it x86: Enable ARCH_USE_BUILTIN_BSWAP x86/xor: Add alternative SSE implementation only prefetching once per 64-byte line x86/xor: Unify SSE-base xor-block routines x86: Fix a typo x86/mm: Fix the argument passed to sync_global_pgds() x86/mm: Convert update_mmu_cache() and update_mmu_cache_pmd() to functions ix86: Tighten asmlinkage_protect() constraints
