ACPI 6.1 introduced new health state flags. Beyond reflecting them in the dimmX/flags sysfs attribute we also need to handle the deeper implications of the ACPI_NFIT_MEM_MAP_FAILED flag which changes assumptions on how the driver discovers dimms. In the "map failed" case there may missing or no SPA entries associated with a dimm. Those dimms should still be registered with libnvdimm so that the error state can be communicated and recovery attempted.
