    Merge branch 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · 4cb38750
    Linus Torvalds authored
    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)
