Subject: [PATCH v3 0/3] Consolidate Poly1305 code and add RISC-V optimization

This series is targeting libcrypto-next.  It can also be retrieved from:

    git fetch https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git poly1305-v3

This series simplifies and optimizes the organization of the Poly1305
code by consolidating it into a single module.  This follows the example
of SHA-1, SHA-256, SHA-512, CRC32, etc.

Since the RISC-V Poly1305 patch has had a moving target, I also rebased
it on top of this series and included it as patch 3.

Changed in v3:
- Added mips/poly1305-core.S and riscv/poly1305-core.S to 'targets'.
  This fixed a bug where the perlasm build step was always running.

Changed in v2:
- Added missing 'FORCE' to the make rules for mips/poly1305-core.S
  and riscv/poly1305-core.S.

    poly1305_is_arch_optimized()
  lib/crypto: poly1305: Consolidate into single module
