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. :)
