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
