Pull virtio fixes from Michael Tsirkin:
"The biggest thing here is the adminq change - but it looks like the
only way to avoid headq blocking causing indefinite stalls.
This fixes three issues:
- Prevent admin commands on one VF blocking another.
This prevents a bad VF from blocking a good one, as well as fixing
a scalability issue with large # of VFs
- Correctly return error on command failure on octeon. We used to
treat failed commands as a success.
- Fix modpost warning when building virtio_dma_buf. Harmless, but the
fix is trivial"
