The device's IO queues are associated with CPUs, so we can use a per-cpu variable to map the a qid to a cpu. This provides a convienient way to optimally assign queues to multiple cpus when the device supports fewer queues than the host has cpus. The previous implementation may have assigned these poorly in these situations. This patch addresses this by sharing queues among cpus that are "close" together and should have a lower lock contention penalty.
