Pull nvdimm updates from Dan Williams:
 "Some small cleanups and fixes in and around the nvdimm subsystem. The
  most significant change is a regression fix for nvdimm namespace
  (volume) creation when the namespace size is smaller than 2MB/

  Summary:

   - Fix nvdimm namespace creation on platforms that do not publish
     associated 'DIMM' metadata for a persistent memory region.

   - Miscellaneous fixes and cleanups"
