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.
