Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost

Pull virtio updates from Michael Tsirkin:
 "Several new features here:

   - Virtio find vqs API has been reworked (required to fix the
     scalability issue we have with adminq, which I hope to merge later
     in the cycle)

   - vDPA driver for Marvell OCTEON

   - virtio fs performance improvement

   - mlx5 migration speedups

  Fixes, cleanups all over the place"
