Merge branch 'work.uaccess-unaligned' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull uacess-unaligned removal from Al Viro: "That stuff had just one user, and an exotic one, at that - binfmt_flat on arm and m68k" * 'work.uaccess-unaligned' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: kill {__,}{get,put}_user_unaligned() binfmt_flat: flat_{get,put}_addr_from_rp() should be able to fail
