Merge branch 'x86-mm-for-linus' of git://git./linux/kernel/git/tip/tip

Pull x86 mm update from Thomas Gleixner:
 "A single patch which excludes the GART aperture from vmcore as
  accessing that area from a dump kernel can crash the kernel.

  Not necessarily the nicest way to fix this, but curing this from
  ground up requires a more thorough rewrite of the whole kexec/kdump
  magic"
