+		* "not_armed"	: Indicates that NVDIMM contents will not
+				  survive a power cycle.
+		* "flush_fail"	: Indicates that NVDIMM contents
+				  couldn't be flushed during last

+		* "restore_fail": Indicates that NVDIMM contents
+				  couldn't be restored during NVDIMM
+				  initialization.
+		* "encrypted"	: NVDIMM contents are encrypted.
