#     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"
