The current arm64 CRC-T10DIF code only runs on cores that implement the
64x64 bit PMULL instructions that are part of the optional Crypto
Extensions, and falls back to the highly inefficient C code otherwise.

Let's provide a SIMD version that is twice as fast as the C code even on
a low end core like the Cortex-A53, and is time invariant and much easier
on the D-cache.

Some performance numbers at the bottom.

Ard Biesheuvel (2):
  crypto: arm64/crct10dif - preparatory refactor for 8x8 PMULL version
  crypto: arm64/crct10dif - implement non-Crypto Extensions alternative
