Ok, I will prepare a 3.14 port. I will send to all recipients of this mail,
that should catch all those who need to sign off on it.

I have generated a version 2 of the original 3.10 patch. No change to
the code diffs, but it changes the commit message to include all of the
original commit followed by a brief description of the back port. Perhaps
this is better?
