[GIT PULL v2] virtio: features, fixes, cleanups

From: Michael S. Tsirkin
Date: Thu May 23 2024 - 02:00:44 EST


Things to note here:
- dropped a couple of patches at the last moment. Did a bunch
of testing in the last day to make sure that's not causing
any fallout, it's a revert and no other changes in the same area
so I feel rather safe doing that.
- the new Marvell OCTEON DPU driver is not here: latest v4 keeps causing
build failures on mips. I kept deferring the pull hoping to get it in
and I might try to 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
- there is a trivial conflict in the header file. Shouldn't be any
trouble to resolve, but fyi the resolution by Stephen is here
