Subject: [PATCH 0/9] Remove per-architecture poly1305 shash glue code

This series removes the per-architecture poly1305 shash glue code and
re-implements the poly1305 shashes on top of the Poly1305 library
functions.  This ends up being much simpler, and it is how it should
have been done originally.  This follows similar changes to crc32,
crc32c, and chacha20.

This series also makes the Poly1305 library be optimized on PowerPC.
Previously the PowerPC-optimized Poly1305 code only supported shash.

Eric Biggers (9):
  crypto: powerpc/poly1305 - implement library instead of shash
  crypto: poly1305 - centralize the shash wrappers for arch code
  crypto: arm/poly1305 - remove redundant shash algorithm
  crypto: arm64/poly1305 - remove redundant shash algorithm
  crypto: mips/poly1305 - drop redundant dependency on CONFIG_MIPS
  crypto: mips/poly1305 - remove redundant shash algorithm
  crypto: x86/poly1305 - remove redundant shash algorithm
  crypto: x86/poly1305 - don't select CRYPTO_LIB_POLY1305_GENERIC
  crypto: poly1305 - remove rset and sset fields of poly1305_desc_ctx
