#     powerpc/papr_scm: Mark nvdimm as unarmed if needed during probe
#     
#     In case an nvdimm is found to be unarmed during probe then set its
#     NDD_UNARMED flag before nvdimm_create(). This would enforce a
#     read-only access to the ndimm region. Presently even if an nvdimm is
#     unarmed its not marked as read-only on ppc64 guests.
#     
#     The patch updates papr_scm_nvdimm_init() to force query of nvdimm
#     health via __drc_pmem_query_health() and if nvdimm is found to be
#     unarmed then set the nvdimm flag ND_UNARMED for nvdimm_create().
