[GIT PULL v2] virtio: features, fixes, cleanups

["Michael S. Tsirkin" <mst@redhat.com>]

Things to note here:
- dropped a couple of patches at the last moment. Did a bunch
  of testing in the last day to make sure that's not causing
  any fallout, it's a revert and no other changes in the same area
  so I feel rather safe doing that.
- the new Marvell OCTEON DPU driver is not here: latest v4 keeps causing
  build failures on mips. I kept deferring the pull hoping to get it in
  and I might try to merge a new version post rc1 (supposed to be ok for
  new drivers as they can't cause regressions), but we'll see.
- there are also a couple bugfixes under review, to be merged after rc1
- there is a trivial conflict in the header file. Shouldn't be any
  trouble to resolve, but fyi the resolution by Stephen is here

virtio: features, fixes, cleanups

Several new features here:
