Subject: [PATCH 3/7] tools/power/x86/turbostat: use kernel MSR #defines
Date: Wed, 14 Nov 2012 15:43:20 -0500	[thread overview]
Message-ID: <38fbc0a1ee900bbdc18fba2d7cfbc4e9b5d51ce8.1352925508.git.len.brown@intel.com> (raw)
In-Reply-To: <1352925804-6746-1-git-send-email-lenb@kernel.org>
In-Reply-To: <39300ffb9b6666714c60735cf854e1280e4e75f4.1352925508.git.len.brown@intel.com>

From: Len Brown <len.brown@intel.com>

Now that turbostat is built in the kernel tree,
it can share MSR #defines with the kernel.
