This is just repost of all patches with fixups squashed in - convenient if you just want to remove old ones from queue and apply new ones. I also tweaked commit log for patch "virtio_pci: modern driver" I also included Gerd's tag: Tested-by: Gerd Hoffmann <kraxel at redhat.com> You can find it all before the rebase -i --autosquash in my tree:

This is on top of 3.19 master + my bugfix patches, and adds virtio 1.0 support to virtio pci. This is 3.20 material I think. Would like to get feedback on s390 change as it's untested.

Changes since v2: handling for devices without config space (e.g. rng) reduce # of mappings for VQs These patches seem to work fine on my virtio-1.0 qemu branch. There haven't been any bugs since v2: just minor cleanups and enhancements. QEMU side is still undergoing polishing, but is already testable. Rusty, what do you think? Let's merge these for 3.20? Also - will you be doing that

This should allow testing when QEMU gets VIRTIO_PCI_CAP_PCI_CFG support, but I'm pretty sure we should never allow these patches upstream. Tested with lguest (in virtio-next), which supports VIRTIO_PCI_CAP_PCI_CFG.
