[PATCH] Re-implemented i586 asm AES
This code is a rework of the original Gladman AES code, and does not
include any supposed BSD licensed work by Jari Ruusu.
Linus converted the Intel asm to Gas format, and made some minor
alterations.
Fruhwirth's glue module has also been retained, although I rebased the
table generation and key scheduling back to Gladman's code. I've tested
this code with some standard FIPS test vectors, and large FTP transfers
over IPSec (both locally and over the wire to a system running the
generic AES implementation).
