Merge tag 'libnvdimm-for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "Some reworks to better support nvdimms on powerpc and an nvdimm
  security interface update:

   - Rework the nvdimm core to accommodate architectures with different
     page sizes and ones that can change supported huge page sizes at
     boot time rather than a compile time constant.

   - Introduce a distinct 'frozen' attribute for the nvdimm security
     state since it is independent of the locked state.

   - Miscellaneous fixups"
