2.6.11-rc4-mm1 contains an option (IEEE80211_CRYPT_CCMP) that selects
CRYPTO_AES - but this is currently wrong on i386.
This patch changes CRYPTO_AES to being the only user-visible options and
selecting either CRYPTO_AES_586 or a new CRYPTO_AES_GENERIC option
depending on the platform.

BTW: Does CRYPTO_AES_586 work on an 386 or 486?

- Rijndael appears to be consistently a very good performer in
- both hardware and software across a wide range of computing
- environments regardless of its use in feedback or non-feedback
- modes. Its key setup time is excellent, and its key agility is
- good. Rijndael's very low memory requirements make it very well
- suited for restricted-space environments, in which it also
- demonstrates excellent performance. Rijndael's operations are
- among the easiest to defend against power and timing attacks.
