Looks like -mm, which really means that either Andrew has to take your
patch, too, or we have to wait until that is upstream until we can merge
your patch.

I'm a little nervous about just acking the patch and telling Andrew to
test it, because I don't know what the fallout would look like. I'm
particularly concerned about gcc version dependencies.

I guess, on the other hand, if it ends up not getting merged until .35
it's not a huge deal either.
