Subject: [PATCH 2/5] edac: Add new memory type for non-volatile DIMMs
Date: Mon, 12 Mar 2018 11:24:27 -0700	[thread overview]
Message-ID: <20180312182430.10335-3-tony.luck@intel.com> (raw)
In-Reply-To: <20180312182430.10335-1-tony.luck@intel.com>

There are now non-volatile versions of DIMMs. Add a new entry to
"enum mem_type" and a new string in edac_mem_types[].
