Re: [PATCH] crypto/sha256.c crypto/sha512.c

From: Jean-Luc Cooke

I updated the faster_sha2.c to include a quick performance test, same URL.

The Ch/sec and Maj/sec can't be easily compared, however instruction
count can to some extent.

http://jlcooke.ca/lkml/faster_sha2_x86.s
http://jlcooke.ca/lkml/faster_sha2_ppc.s
http://jlcooke.ca/lkml/faster_sha2_alpha.s
http://jlcooke.ca/lkml/faster_sha2_sparc.s

Hope this helps, I'll know better next time I ask for patch-blessing. :)
