Subject[PATCH 00/80] TTY updates for 2.6.28
Date
The big thrust of this is krefs. The tty and tty drivers are now kref accounted
and this allows some of the locking to be simplified. The pty special casing
has been mostly pushed into the pty layer and the open paths simplified so we
are close to disposing of the BKL on open/close.

Also fix a pile of bugs found in the tty layer during this process and in
driver code.

Finally we add the basics of termiox (the standard Unix termios extension) as
bits of it are now needed by people wanting things like non-standard handshake.

Resynched against the current git tree as of this morning.
