Ok, we found two patches that were missing in 4.4-stable that were in
the SLES12 tree (thanks to Jamie Iles), now I only have 19k more to sift
through :)

I should probably do an "interm" release to get people to be able to
sync up to a common place easier for testing, dealing with patch sets
and random emails saying different git ids is not easy for anyone.
