Subject: [PATCH 1/5] trace, RAS: Add basic RAS trace event
Date: Fri, 28 Mar 2014 01:52:57 -0400	[thread overview]
Message-ID: <1395985981-20476-2-git-send-email-gong.chen@linux.intel.com> (raw)
In-Reply-To: <1395985981-20476-1-git-send-email-gong.chen@linux.intel.com>

To avoid the confuision of usage for RAS related trace event, add
an unified RAS trace event stub.
