Subject: [PATCH 4/4] x86: add CONFIG_X86_MOVBE option
Date: Tue, 4 Dec 2012 10:15:30 +0000 [thread overview]
Message-ID: <1354616130-21587-5-git-send-email-dwmw2@infradead.org> (raw)
In-Reply-To: <1354616130-21587-1-git-send-email-dwmw2@infradead.org>
From: David Woodhouse <David.Woodhouse@intel.com>
Currently depends only on CONFIG_MATOM. This will change because big-core
CPUs are getting movbe too...
