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

v6: - add patch 1/2 to make sparc architecture happy. [Sam] - close created sessions previousely when rekeying. - convert the priority of virtio crypto algs from 4001 to 501 which is enough. v5: - add comments for algs_lock and table_lock. [Stefan] - use kzfree instead of kfree for key material security. [Stefan] - drop unnecessary spin_lock for struct virtio_crypto_ablkcipher_ctx. -
