Merge tag 'libnvdimm-for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Browse Source 
Pull libnvdimm updates from Dan Williams:
 "The highlight this cycle is continuing integration fixes for PowerPC
  and some resulting optimizations.

  Summary:

   - Updates to better support vmalloc space restrictions on PowerPC
     platforms.

   - Cleanups to move common sysfs attributes to core 'struct
     device_type' objects.

   - Export the 'target_node' attribute (the effective numa node if pmem
     is marked online) for regions and namespaces.

   - Miscellaneous fixups and optimizations"
