Jason A. Donenfeld	109e23bd10	crypto: poly1305 - Use unaligned access where required ... By using the unaligned access helpers, we drastically improve performance on small MIPS routers that have to go through the exception fix-up handler for these unaligned accesses.

Martin Willi	2546f811ef	crypto: poly1305 - Export common Poly1305 helpers ... As architecture specific drivers need a software fallback, export Poly1305 init/update/final functions together with some helpers in a header file.

Martin Willi	c2b7b20aed	crypto: poly1305 - Pass key as first two message blocks to each desc_ctx ... The Poly1305 authenticator requires a unique key for each generated tag. This implies that we can't set the key per tfm, as multiple users set individual keys. Instead we pass a desc specific key as the first two blocks of the message to authenticate in update().

Martin Willi	f979e014c5	crypto: poly1305 - Add a generic Poly1305 authenticator implementation ... Poly1305 is a fast message authenticator designed by Daniel J. Bernstein. It is further defined in RFC7539 as a building block for the ChaCha20-Poly1305 AEAD for use in IETF protocols. This is a portable C implementation of the algorithm without architecture specific optimizations, based on public domain code by Daniel J. Bernstein and Andrew Moon.
