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