crypto: x86/sha - Eliminate casts on asm implementations
In order to avoid CFI function prototype mismatches, this removes the casts on assembly implementations of sha1/256/512 accelerators. The safety checks from BUILD_BUG_ON() remain. Additionally, this renames various arguments for clarity, as suggested by Eric Biggers. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
