    Merge branch 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · da834796
    Linus Torvalds authored
    Pull x86/asm changes from Ingo Molnar:
     "The one change that stands out is the alternatives patching change
      that prevents us from ever patching back instructions from SMP to UP:
      this simplifies things and speeds up CPU hotplug.
    
      Other than that it's smaller fixes, cleanups and improvements."
