[PATCH post-squash 0/9] virtio 1.0: virtio-pci fixup
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:
