v3: - set cpu affinity when data queues are not equal to the number of online cpus. [Michael] - add TODO comments for cpu hotplug (changing the relationship of binding virtqueue and cpu) - use __u32/64 in the config space since the virtio->get() doesn't support byte-swap yet. [Michael] - drop the whole patch 1 of v2 because the above reason. - add VERSION_1 check at the beginning of
