From 8610d7bf608923157aee95cea30e162ed3417658 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 30 Dec 2013 15:52:24 +0200 Subject: [PATCH] crypto: aesni - fix build on x86 (32bit) It seems commit d764593a "crypto: aesni - AVX and AVX2 version of AESNI-GCM encode and decode" breaks a build on x86_32 since it's designed only for x86_64. This patch makes a compilation unit conditional to CONFIG_64BIT and functions usage to CONFIG_X86_64.
