As before, this patchset is dependent on the 'ldsem patchset'.
The reason is that this series abandons tty->receive_room as
a flow control mechanism (because that requires locking),
and the TIOCSETD ioctl _without ldsem_ uses tty->receive_room
to shutoff i/o.

It is also dependent on 'n_tty fixes' which I recently resent
to you.

Thanks for rebasing all of this, and resending it. It's late in the
3.11 development cycle, so I'm going to wait unto 3.11-rc1 is out to
queue it up for 3.12, to get it lots of testing in linux-next.

Thanks Greg. I actually meant to suggest these be held until after
the merge window but I got distracted by the VT1 deallocation bug
