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

The virtio crypto device is a virtual cryptography device as well as a kind of virtual hardware accelerator for virtual machines. The encryption anddecryption requests are placed in the data queue and are ultimately handled by thebackend crypto accelerators. The second queue is the control queue used to create or destroy sessions for symmetric algorithms and will control some advanced features in

v4: - rework unknow status bit handler by calling virtio_break_device(). [Cornelia] - convert space to tab in Kconfig. [Stefan] - rename virtio_crypto.c to virtio_crypto_core.c and then make the moudle named virtio_crypto.ko for consistency. [Stefan] - don't call virtcrypto_dev_stop() on failure path. [Stefan] - don't add two empty lines. [Michael] - fix possible race by add
