    libnvdimm, pmem: fix persistence warning · c00b396e
    Dan Williams authored
    The pmem driver assumes if platform firmware describes the memory
    devices associated with a persistent memory range and
    CONFIG_ARCH_HAS_PMEM_API=y that it has all the mechanism necessary to
    flush data to a power-fail safe zone. We warn if the firmware does not
    describe memory devices, but we also need to warn if the architecture
    does not claim pmem support.
