This is just the full patchset reposted with fixups in correct order, before squashing them. 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: git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git virtio-next

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
