Subject: [PATCH 3/5] x86, cpu: Remove gcc 3.x workarounds in <asm/cpufeature.h>
Date: Mon, 13 Sep 2010 13:14:38 -0700 [thread overview]
Message-ID: <1284408880-14414-4-git-send-email-hpa@linux.intel.com> (raw)
In-Reply-To: <1284408880-14414-1-git-send-email-hpa@linux.intel.com>
We no longer support gcc 3.x, so remove the workaround for it.
