I think we could have done better there, yes, but not all of our patches
were appropriate for backporting, especially those parts that touched
outside of the port.  There will be portions of power8 we won't/don't
want to backport either, but I would like to get the major backend
portions like machine description files and the like backported to
4.8 when the time comes.  Having the configurey changes in would help
that, but if you say those are things we can get in after stage1,
then that can ease things a bit.  That said, I'll post our current
patch as is and discuss within our team and with David on what our
next course of action should be.
