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" * tag 'libnvdimm-for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (21 commits) MAINTAINERS: Remove Keith from NVDIMM maintainers libnvdimm: Export the target_node attribute for regions and namespaces dax: Add numa_node to the default device-dax attributes libnvdimm: Simplify root read-only definition for the 'resource' attribute dax: Simplify root read-only definition for the 'resource' attribute dax: Create a dax device_type libnvdimm: Move nvdimm_bus_attribute_group to device_type libnvdimm: Move nvdimm_attribute_group to device_type libnvdimm: Move nd_mapping_attribute_group to device_type libnvdimm: Move nd_region_attribute_group to device_type libnvdimm: Move nd_numa_attribute_group to device_type libnvdimm: Move nd_device_attribute_group to device_type libnvdimm: Move region attribute group definition libnvdimm: Move attribute groups to device type libnvdimm: Remove prototypes for nonexistent functions libnvdimm/btt: fix variable 'rc' set but not used libnvdimm/pmem: Delete include of nd-core.h libnvdimm/namespace: Differentiate between probe mapping and runtime mapping libnvdimm/pfn_dev: Don't clear device memmap area during generic namespace probe libnvdimm: Trivial comment fix ...
