Alright, we'll have to notify Greg/stable when it goes in.

You just add a:
Cc: stable@kernel.org
where the signed-off-by is. If you know the versions it should be applied to, you can add that information as well. For this case, you would have done:
Cc: stable@kernel.org # v3.13+
to get it into 3.13 stable and later.
