Thanks for all the work bisecting / etc... Note that you can get patch
reverted if it causes regression, but it needs to be done over
email. (If maintainer does not reply, up-to Linus).

For the record, patch is:

git bisect output:

And the patch was tagged for stable, which sounds like a lot of fun.

I added Ccs to people involved with the patch.
