There's no problem with doing this... but you should get some debate
(with Linus?) whether using freezer for cgroups is sane. When that is
done, there's no problem with this going in, probably through rafael's
patch queue.

(The first patch -- add freezer for all archs -- is probably
reasonably to go in ASAP, through akpm or something...)
