From 3387e7d69048f5ab02729825f9611754850d9a87 Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Thu, 14 Jun 2012 10:09:03 +0800 Subject: crypto: serpent-sse2/avx - allow both to be built into kernel Rename serpent-avx assembler functions so that they do not collide with serpent-sse2 assembler functions when linking both versions in to same kernel image.
