crypto: blake2s - x86_64 SIMD implementation
These implementations from Samuel Neves support AVX and AVX-512VL. Originally this used AVX-512F, but Skylake thermal throttling made AVX-512VL more attractive and possible to do with negligable difference. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: Samuel Neves <sneves@dei.uc.pt> Co-developed-by: Samuel Neves <sneves@dei.uc.pt> [ardb: move to arch/x86/crypto, wire into lib/crypto framework] Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
