Subject: [GIT PULL] virtio: features, fixes, cleanups
Things to note here:
- the new Marvell OCTEON DPU driver is not here: latest v4 keeps causing
build failures on mips. I deferred the pull hoping to get it in
and I might merge a new version post rc1
(supposed to be ok for new drivers as they can't cause regressions),
but we'll see.
- there are also a couple bugfixes under review, to be merged after rc1
- I merged a trivial patch (removing a comment) that also got
merged through net.
git handles this just fine and it did not seem worth it
rebasing to drop it.
- there is a trivial conflict in the header file. Shouldn't be any
trouble to resolve, but fyi the resolution by Stephen is here

Merge tag 'for_linus' into vhost (2024-05-12 08:15:28 -0400)
----------------------------------------------------------------
virtio: features, fixes, cleanups
Several new features here:
- virtio-net is finally supported in vduse.
- Virtio (balloon and mem) interaction with suspend is improved
- vhost-scsi now handles signals better/faster.
- virtio-net now supports premapped mode by default,
opening the door for all kind of zero copy tricks.
Fixes, cleanups all over the place.
