Merge branch 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86/mm changes from Peter Anvin: "The big change here is the patchset by Alex Shi to use INVLPG to flush only the affected pages when we only need to flush a small page range. It also removes the special INVALIDATE_TLB_VECTOR interrupts (32 vectors!) and replace it with an ordinary IPI function call." Fix up trivial conflicts in arch/x86/include/asm/apic.h (added code next to changed line) * 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tlb: Fix build warning and crash when building for !SMP x86/tlb: do flush_tlb_kernel_range by 'invlpg' x86/tlb: replace INVALIDATE_TLB_VECTOR by CALL_FUNCTION_VECTOR x86/tlb: enable tlb flush range support for x86 mm/mmu_gather: enable tlb flush range in generic mmu_gather x86/tlb: add tlb_flushall_shift knob into debugfs x86/tlb: add tlb_flushall_shift for specific CPU x86/tlb: fall back to flush all when meet a THP large page x86/flush_tlb: try flush_tlb_single one by one in flush_tlb_range x86/tlb_info: get last level TLB entry number of CPU x86: Add read_mostly declaration/definition to variables from smp.h x86: Define early read-mostly per-cpu macros
