It depends on https://lkml.org/lkml/2013/12/5/172 which I noted in the
cover letter. At this point, I don't know if Kamil's whole series will
make it to 3.14 so that patch may have to be taken separately. He has a
trivial update to make on the binding example is all for this patch.

I was wondering today if we might just want to separate that out now. I
originally had a similar patch in my series but his was posted first so
I rebased on that.
