Ard Biesheuvel	b913a6404c	arm64/crypto: improve performance of GHASH algorithm ... This patches modifies the GHASH secure hash implementation to switch to a faster, polynomial multiplication based reduction instead of one that uses shifts and rotates.

Ard Biesheuvel	fdd2389457	arm64/crypto: GHASH secure hash using ARMv8 Crypto Extensions ... This is a port to ARMv8 (Crypto Extensions) of the Intel implementation of the GHASH Secure Hash (used in the Galois/Counter chaining mode). It relies on the optional PMULL/PMULL2 instruction (polynomial multiply long, what Intel call carry-less multiply).
