Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull virtio updates from Michael Tsirkin:
"virtio: virtio 1.0 support, misc patches
This adds a lot of infrastructure for virtio 1.0 support. Notable
missing pieces: virtio pci, virtio balloon (needs spec extension),
vhost scsi.
Plus, there are some minor fixes in a couple of places.
Note: some net drivers are affected by these patches. David said he's
fine with merging these patches through my tree.
Rusty's on vacation, he acked using my tree for these, too"
