Too late now, we'll have to apply it in 3.4 and flag it for -stable. -rc7
is not the time to be testing and submitting fixes that should have been
done during -rc3 time or so.

Ok, I've applied it to my fixes branch for now. If there's another rc
I'll send it off to Linus, otherwise Rafael can pull in my outstanding
fixes later on.
