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

Pull x86 cleanups from Ingo Molnar:
 "This topic tree contains more commits than usual:

   - most of it are uaccess cleanups/reorganization by Al

   - there's a bunch of prototype declaration (--Wmissing-prototypes)
     cleanups

   - misc other cleanups all around the map"
