My first patch which try to add skcipher was Nacked, it will add too many functions and adding other algs(aead, asymetric_key) will make the situation worst. This patchset remove all algs specific stuff and now only process generic crypto_async_request. The requests handler function pointer are now moved out of struct engine and are now stored directly in a crypto_engine_reqctx. The original proposal of Herbert [1] cannot be done completly since the crypto_engine could only dequeue crypto_async_request and it is impossible to access any request_ctx without knowing the underlying request type. So I do something near that was requested: adding crypto_engine_reqctx in TFM context. Note that the current implementation expect that crypto_engine_reqctx is the first member of the context. The first patch convert the crypto engine with the new way, while the following patchs convert the 3 existing users of crypto_engine. Note that this split break bisection, so probably the final commit will be all merged. The 3 latest patch were compile tested only, but the first is tested successfully with my new sun8i-ce driver.
