Hello

Thanks for your ack, but Thomas Gleixner in the same time NACK this patch.
Just in case I attach the new patch, for permit you to decide which one you prefer.

Subject: [PATCH] crypto: x86: Remove duplicate define of SHA1_DIGEST_SIZE

The sha x86 crypto code use two define for the same thing:
NUM_SHA1_DIGEST_WORDS and SHA1_DIGEST_LENGTH
Replace them by SHA1_DIGEST_SIZE/4

#define SHA1_DIGEST_WORDS (SHA1_DIGEST_SIZE / sizeof(u32))

moved to sha1.h

Suggest to move SHA1_DIGEST_WORDS to sha1.h
