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

Pull x86 asmlinkage (LTO) changes from Peter Anvin:
 "This patchset adds more infrastructure for link time optimization
  (LTO).

  This patchset was pulled into my tree late because of a
  miscommunication (part of the patchset was picked up by other
  maintainers).  However, the patchset is strictly build-related and
  seems to be okay in testing"
