[CRYPTO] padlock: Helper module padlock.ko
Compile a helper module padlock.ko that will try to autoload all configured padlock algorithms. This also provides backward compatibility with the ancient times before padlock.ko was renamed to padlock-aes.ko Signed-off-by: Michal Ludvig <michal@logix.cz> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
