[PATCH v2 00/10] Optimize SHA256 and SHA512 for Intel x86_64 withSSSE3, AVX or AVX2 instructions

[Tim Chen]

Herbert, 

The following patch series provides optimized SHA256 and SHA512 routines
using the SSSE3, AVX or AVX2 instructions on x86_64 for Intel cpus.
Depending on cpu capabilities, speedup between 40% to 70% or more can be achieved
over the generic SHA256 and SHA512 routines.

Tim

Version 2:

1. Check AVX2 feature directly in glue code
2. Add CONFGI_AS_AVX2 check for AVX2 code
3. Use ENTRY/ENDPROC macros for assembly routines
4. Fix SSSE3 feature check in glue code

Thanks to Peter Anvin, Jussi Kivilinna and Jim Kukunas for their reviews and comments.
