From 1eac887772928a61808339f51166be7f8b23babd Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Wed, 23 Jul 2014 17:26:40 +0200 Subject: [PATCH] drm: drop i386 verification Linux doesn't run on i386, anymore. See: commit d55c5a93db2d5fa95f233ab153f594365d95b777 Author: H. Peter Anvin Date: Wed Nov 28 11:50:24 2012 -0800 x86, 386 removal: Remove CONFIG_CMPXCHG All 486+ CPUs support CMPXCHG, so remove the fallback 386 support code. Furthermore, as the commit-message states, all 486+ CPUs support the CMPXCHG instruction and thus even legacy DRM can run fine. Drop the now superfluous "x86 == 3" check.
