this series adds multiqueue support to the virtio-scsi driver, based
on Jason Wang's work on virtio-net.  It uses a simple queue steering
algorithm that expects one queue per CPU.  LUNs in the same target always
use the same queue (so that commands are not reordered); queue switching
occurs when the request being queued is the only one for the target.
Also based on Jason's patches, the virtqueue affinity is set so that
each CPU is associated to one virtqueue.

Is there a spec patch? I did not see one.

It was already in the first version of the spec, just not implemented
until now.
