Subject: [patch 02/50] sha512: Fix sha384 block size

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Herbert Xu <herbert@gondor.apana.org.au>

The SHA384 block size should be 128 bytes, not 96 bytes.  This was
spotted by Andrew Donofrio.

This breaks HMAC which uses the block size during setup and the final
calculation.
