As Bjorn noted in[1] there appears to be some potential for cleaning things up and removing duplication though. This series attempts to do this cleanup (Patches 1 and 2) followed by enabling isolated PCI functions for s390 (Patches 3 and 4). If need be I can of course split the cleanup off but for now I kept it as one as that's what I have been testing.
