Herbert Xu 0ee4a96902 crypto: aes - Precompute tables
The tables used by the various AES algorithms are currently
computed at run-time.  This has created an init ordering problem
because some AES algorithms may be registered before the tables
have been initialised.

This patch gets around this whole thing by precomputing the tables.

Sebastian Siewior 5427663f49 [CRYPTO] aes: Export generic setkey
The key expansion routine could be get little more generic, become
a kernel doc entry and then get exported.

Sebastian Siewior 96e82e4551 [CRYPTO] aes-generic: Make key generation exportable
This patch exports four tables and the set_key() routine. This ressources
can be shared by other AES implementations (aes-x86_64 for instance).
The decryption key has been turned around (deckey[0] is the first piece
of the key instead of deckey[keylen+20]). The encrypt/decrypt functions
are looking now identical (except they are using different tables and
key).
