Switch from the old AES library functions (which use struct crypto_aes_ctx) to the new ones (which use struct aes_enckey). This eliminates the unnecessary computation and caching of the decryption round keys. The new AES en/decryption functions are also much faster and use AES instructions when supported by the CPU. Note that in addition to the change in the key preparation function and the key struct type itself, the change in the type of the key struct results in aes_encrypt() (which is temporarily a type-generic macro) calling the new encryption function rather than the old one.
