I only skimmed the series for obvious hickups vs. the PCI/MSI core (my virt[io] foo is limited) and I did not find anything to complain about. Aside of that I really like how this series is built up to restructure and cleanup things first so that the new functionality falls in place instead of the popular 'glue it in no matter what' approach. That's a pleasure to read even for the virt[io] illiterate! Acked-by: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Thanks, tglx
