Merge branch 'work.tty-ioctl' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull tty ioctl updates from Al Viro: "This is the compat_ioctl work related to tty ioctls. Quite a bit of dead code taken out, all tty-related stuff gone from fs/compat_ioctl.c. A bunch of compat bugs fixed - some still remain, but all more or less generic tty-related ioctls should be covered (remaining issues are in things like driver-private ioctls in a pcmcia serial card driver not getting properly handled in 32bit processes on 64bit host, etc)" * 'work.tty-ioctl' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (53 commits) kill TIOCSERGSTRUCT change semantics of ldisc ->compat_ioctl() kill TIOCSER[SG]WILD synclink_gt(): fix compat_ioctl() pty: fix compat ioctls compat_ioctl - kill keyboard ioctl handling gigaset: add ->compat_ioctl() vt_compat_ioctl(): clean up, use compat_ptr() properly gigaset: don't try to printk userland buffer contents dgnc: don't bother with (empty) stub for TCXONC dgnc: leave TIOC[GS]SOFTCAR to ldisc remove fallback to drivers for TIOCGICOUNT dgnc: break-related ioctls won't reach ->ioctl() kill the rest of tty COMPAT_IOCTL() entries dgnc: TIOCM... won't reach ->ioctl() isdn_tty: TCSBRK{,P} won't reach ->ioctl() kill capinc_tty_ioctl() take compat TIOC[SG]SERIAL treatment into tty_compat_ioctl() synclink: reduce pointless checks in ->ioctl() complete ->[sg]et_serial() switchover ...
