Pull misc fixes from Al Viro: "Loose ends and regressions from the last merge window. Strictly speaking, only binfmt_flat thing is a build regression per se - the rest is 'only sparse cares about that' stuff" [ This came in before the 4.13 release and could have gone there, but it was late in the release and nothing seemed critical enough to care, so I'm pulling it in the 4.14 merge window instead - Linus ] * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: binfmt_flat: fix arch/m32r and arch/microblaze flat_put_addr_at_rp() compat_hdio_ioctl: Fix a declaration <linux/uaccess.h>: Fix copy_in_user() declaration annotate RWF_... flags teach SYSCALL_DEFINE/COMPAT_SYSCALL_DEFINE to handle __bitwise arguments
