Subject[PATCH] Blackfin: sync termios header changes with x86
Date
The Blackfin port copied the x86 termios interface, so pull updates from
it to get the latest termios ioctls and such.

Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Arnd: if you don't mind, i'd rather merge this ... i can put it into my
next batch of Blackfin changes for 2.6.31
