linux-next: manual merge of the vhost tree with the virtio tree

Hi Michael,

Today's linux-next merge of the vhost tree got a conflict in
drivers/virtio/virtio_balloon.c between commit df81b29c7b81
("virtio_balloon: transitional interface") from the virtio tree and
commit 263f23c089f2 ("virtio_balloon: transitional interface") from the
vhost tree.

I fixed it up (by using the version of the files from the virtio tree)
and can carry the fix as necessary.  Please clean up this mess ...

Hi Michael,

Today's linux-next merge of the vhost tree got a conflict in
drivers/virtio/virtio_balloon.c between commit 7f8998200dcb
("virtio_balloon: annotate possible sleep waiting for event") from the
virtio tree and commit 2426d3b03d07 ("virtio-balloon: do not call
blocking ops when !TASK_RUNNING") from the vhost tree.

I fixed it up (I think - see below) and can carry the fix as necessary
(no action is required).

linux-next: manual merge of the vhost tree with the virtio tree

Hi Michael,

Today's linux-next merge of the vhost tree got a conflict in
drivers/vhost/Makefile between commit 4d8dc8b44748 ("vringh: host-side
implementation of virtio rings") from the virtio tree and commit
0b87bfefde9a ("vhost-blk: Add vhost-blk support v6") from the vhost tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
