Merge tag 'libnvdimm-fixes-5.2-rc1' of git://git./linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "Just a small collection of fixes this time around.

  The new virtio-pmem driver is nearly ready, but some last minute
  device-mapper acks and virtio questions made it prudent to await v5.3.

  Other major topics that were brewing on the linux-nvdimm mailing list
  like sub-section hotplug, and other devm_memremap_pages() reworks will
  go upstream through Andrew's tree.

  Summary:

   - Fix a long standing namespace label corruption scenario when
     re-provisioning capacity for a namespace.

   - Restore the ability of the dax_pmem module to be built-in.

   - Harden the build for the 'nfit_test' unit test modules so that the
     userspace test harness can ensure all required test modules are
     available"
