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

Pull x86 sigcontext header cleanups from Ingo Molnar:
 "This series reorganizes and cleans up various aspects of the main
  sigcontext UAPI headers, such as unifying the data structures and
  updating/adding lots of comments to explain all the ABI details and
  quirks.  The headers can now also be built in user-space standalone"
