-From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
-From: "Jason A. Donenfeld" <Jason@zx2c4.com>
-Date: Fri, 8 Nov 2019 13:22:31 +0100
-Subject: [PATCH] crypto: blake2s - x86_64 SIMD implementation
-
-commit ed0356eda153f6a95649e11feb7b07083caf9e20 upstream.
-
-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.
