Merge branch 'work.compat' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull fs/compat.c cleanups from Al Viro: "More moving of compat syscalls from fs/compat.c to fs/*.c where the native counterparts live. And death to compat_sys_getdents64() - the only architecture that used to need it was ia64, and _that_ has lost biarch support quite a few years ago" * 'work.compat' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fs/compat.c: trim unused includes move compat_rw_copy_check_uvector() over to fs/read_write.c fhandle: move compat syscalls from compat.c open: move compat syscalls from compat.c stat: move compat syscalls from compat.c fcntl: move compat syscalls from compat.c readdir: move compat syscalls from compat.c statfs: move compat syscalls from compat.c utimes: move compat syscalls from compat.c move compat select-related syscalls to fs/select.c Remove compat_sys_getdents64()
