From ee71e5f1e7d25543ee63a80451871f8985b8d431 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 11 Oct 2016 19:15:15 +0100 Subject: crypto: arm64/sha1-ce - fix for big endian The SHA1 digest is an array of 5 32-bit quantities, so we should refer to them as such in order for this code to work correctly when built for big endian. So replace 16 byte scalar loads and stores with 4x4 vector ones where appropriate.
