Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull more vfs mount updates from Al Viro: "Propagation of new syscalls to other architectures + cosmetic change from Christian (fscontext didn't follow the convention for anon inode names)" * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: uapi: Wire up the mount API syscalls on non-x86 arches [ver #2] uapi, x86: Fix the syscall numbering of the mount API syscalls [ver #2] uapi, fsopen: use square brackets around "fscontext" [ver #2]
