    libnvdimm, nfit: enable support for volatile ranges · c9e582aa

    Allow volatile nfit ranges to participate in all the same infrastructure
    provided for persistent memory regions. A resulting resulting namespace
    device will still be called "pmem", but the parent region type will be
    "nd_volatile". This is in preparation for disabling the dax ->flush()
    operation in the pmem driver when it is hosted on a volatile range.
