Subject: [CRYPTO] aes: Rename aes to aes-generic
X-Git-Tag: v2.6.24-rc1~1454^2~47
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f8246af005d56b73f4f04304fc5b6fd9878af4ef;p=linux-2.6

[CRYPTO] aes: Rename aes to aes-generic

Loading the crypto algorithm by the alias instead of by module directly
has the advantage that all possible implementations of this algorithm
are loaded automatically and the crypto API can choose the best one
depending on its priority.

Additionally it ensures that the generic implementation as well as the
HW driver (if available) is loaded in case the HW driver needs the
generic version as fallback in corner cases.
