Subject: [PATCH v2 8/9] ACPI, APEI, CPER: Cleanup CPER memory error output format
Date: Wed, 16 Oct 2013 10:56:05 -0400	[thread overview]
Message-ID: <1381935366-11731-9-git-send-email-gong.chen@linux.intel.com> (raw)
In-Reply-To: <1381935366-11731-1-git-send-email-gong.chen@linux.intel.com>

Keep up only the most important fields for memory error
reporting. The detail information will be moved to perf/trace
interface.
