Subject: [PATCH] Fix prototype definitions of sha256_transform_asm, 
 sha512_transform_asm

Herbert,

This is a follow on patch to the optimized sha256 and sha512 patch series that's just
merged into the crypto-dev.  Let me know if you prefer me to respin the
patch series.

This patch corrects the prototype of sha256_transform_asm and
sha512_transform_asm function pointer declaration to static.  It also
fixes a typo in sha512_ssse3_final function that affects the computation
of upper 64 bits of the buffer size.

Thanks.

Tim
