Merge branch 'uaccess.strlen' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull user access str* updates from Al Viro: "uaccess str...() dead code removal" * 'uaccess.strlen' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: s390 keyboard.c: don't open-code strndup_user() mips: get rid of unused __strnlen_user() get rid of unused __strncpy_from_user() instances kill strlen_user()
