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.
