Linus Torvalds 10826505f5 virtio: fixes
This fixes 3 issues:
 - prevent admin commands on one VF blocking another:
   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:
   currently if any commands fail we treat it as success
 - fix modpost warning when building virtio_dma_buf:
   harmless, but the fix is trivial

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"
