Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull vhost fixes from Michael Tsirkin:
"Fixes all over the place.
A new UAPI is borderline: can also be considered a new feature but
also seems to be the only way we could come up with to fix addressing
for userspace - and it seems important to switch to it now before
userspace making assumptions about addressing ability of devices is
set in stone"
