2.6.25-stable review patch. If anyone has any objections, please let us
know.

From: Alan Cox <alan@xxxxxxxxxx>

commit 8f520021837d45c47d0ab57e7271f8d88bf7f3a4 upstream

(only the tty_io.c portion of this commit)

This moves us towards sanity and should mean our termios locking is now
complete and comprehensive.
