Lets add this version to kvms390/master. This already is much much better
than the current 7.0-rc state. It is hard to review the differences and
we want to get these fixes queued asap. kvms390/master is picked up by
next so we will have CI coverage inside (and outside) of IBM.

If something is really broken we can refresh kvms390/master, otherwise
we can still do followup patches.
