This looks good, however I'd like to see Aaron's changes go in first,
and then yours. Aaron's changes still need to be tested by 0-day and I
need to finish review, but that's the order of how I'd prefer to see
changes merged / tested. I'll try to review his changes, dump them to
modules-next and then I'd like to trouble you to rebase ontop of that.

We should get all this tested early for the next release.
