Subject[PATCH v2 0/2] crypto, x86: assembler implementation of SHA1
Date
This patch series adds an assembler implementation for the SHA1 hash algorithm
for the x86-64 architecture. Its raw hash performance can be more than 2 times
faster than the generic C implementation. This gives a real world benefit for
IPsec with an throughput increase of up to +35%. For concrete numbers have a
look at the second patch.

This implementation is currently x86-64 only but might be ported to 32 bit with
some effort in a follow up patch. (I had no time to do this yet.)

Note: The SSSE3 is no typo, it's "Supplemental SSE3".

v2 changes:
- fixed typo in Makefile making AVX version unusable
- whitespace fixes for the .S file

Regards,
Mathias
