[git pull] tty ioctl cleanups and fixes
From: Al Viro
Date: Tue Oct 23 2018 - 00:08:05 EST
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.)
Posted, ACKed by tty maintainers, sat in -next for weeks now.
The following changes since commit 5b394b2ddf0347bef56e50c69a58773c94343ff3:

complete ->[sg]et_serial() switchover
synclink: reduce pointless checks in ->ioctl()
take compat TIOC[SG]SERIAL treatment into tty_compat_ioctl()
kill capinc_tty_ioctl()
isdn_tty: TCSBRK{,P} won't reach ->ioctl()
dgnc: TIOCM... won't reach ->ioctl()
kill the rest of tty COMPAT_IOCTL() entries
dgnc: break-related ioctls won't reach ->ioctl()
remove fallback to drivers for TIOCGICOUNT
dgnc: leave TIOC[GS]SOFTCAR to ldisc
dgnc: don't bother with (empty) stub for TCXONC
gigaset: don't try to printk userland buffer contents
vt_compat_ioctl(): clean up, use compat_ptr() properly
gigaset: add ->compat_ioctl()
compat_ioctl - kill keyboard ioctl handling
