commit ffd9b2aa5abda7f4d7790ed48116ed5d71ab9995
Author: Jussi Kivilinna <jussi.kivilinna at iki.fi>
Date:   Sat Dec 14 11:23:03 2013 +0200

    Minor fixes to SHA assembly implementations
    
    * cipher/Makefile.am: Correct 'sha256-avx*.S' to 'sha512-avx*.S'.
    * cipher/sha1-ssse3-amd64.S: First line, correct filename.
    * cipher/sha256-ssse3-amd64.S: Return correct stack burn depth.
    * cipher/sha512-avx-amd64.S: Use 'vzeroall' to clear registers.
    * cipher/sha512-avx2-bmi2-amd64.S: Ditto and return correct stack burn
    depth.
