So it's needed in 3.1.x and 3.2.x?

Indeed it would be needed in -stable, thanks, I forgot to add that.

And although Fedora only got reports from 3.1 onwards, I believe it
would equally be needed in 3.0.x.  3.1.x is closed down now, but
3.0.x and 3.2.x are still open.

I've not yet tried applying it to the latest of either of those: maybe
it applies cleanly and correctly, but I could imagine movements too.
But the first step, yes, is to Cc: stable@vger.kernel.org

I don't see this in linux-next, 3.3-rcX, the stable-queue, or really
anywhere at all at the moment.  Did the patch get swallowed up by some
kind of evil code Eagle of Doom before making it into the safety of a
tree somewhere?

I have it queued for 3.3.  It's taking a while to get things into -next
at present because they're breaking things faster than I can fix them :(
