[PATCH v2 00/18] crypto: Provide clmul.h and host accel

[Richard Henderson]

Inspired by Ard Biesheuvel's RFC patches [1] for accelerating
carry-less multiply under emulation.

Changes for v2:
  * Only accelerate clmul_64; keep generic helpers for other sizes.
  * Drop most of the Int128 interfaces, except for clmul_64.
  * Use the same acceleration format as aes-round.h.
