The patch titled
tty: fix tty network driver interactions with TCGET/TCSET calls (x86 fix)
has been removed from the -mm tree. Its filename was
tty-fix-tty-network-driver-interactions-with-tcget-tcset-calls-x86-fix.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: tty: fix tty network driver interactions with TCGET/TCSET calls (x86 fix)
From: Dave Miller <davem@xxxxxxxxxxxxx>
And to go with it Dave's type checking x86 termios headers. I've updated
these as the original sent by Dave had some wrong types in it.
