OK, lets try this. One worry at the back of my mind is the fallout we
had when we re-synced to v3.7.1 and tested things as best we were able
to prior to merge. I think it's too late in the cycle to pull this in
for v2014.07, but lets get something in for v2014.10. And since v3.15
is already out, lets do (as part of testing our theories out), a follow
up patch to sync up with v3.15. And finally, I think we need, in order
to keep this pain point down, sync per kernel release.
