Merge branch 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Browse Source 
Pull x86 EFI updates from Peter Anvin:
 "This patchset falls under the "maintainers that grovel" clause in the
  v3.18-rc1 announcement.  We had intended to push it late in the merge
  window since we got it into the -tip tree relatively late.

  Many of these are relatively simple things, but there are a couple of
  key bits, especially Ard's and Matt's patches"
