[PADLOCK] Move fast path work into aes_set_key and upper layer
Most of the work done aes_padlock can be done in aes_set_key. This means that we only have to do it once when the key changes rather than every time we perform an encryption or decryption. This patch also sets cra_alignmask to let the upper layer ensure that the buffers fed to us are aligned correctly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
