Pull libnvdimm fixes from Dan Williams:
"A fix for a regression added this cycle in the pmem driver, and for a
long standing bug for failed NUMA node lookups on ARM64.

This has appeared in -next for several days with no reported issues.

Summary:

- Fix a regression that caused the sysfs ABI for pmem block devices
to not be registered. This fails the nvdimm unit tests and dax
xfstests.

- Fix numa node lookups for dax-kmem memory (device-dax memory
assigned to the page allocator) on ARM64"
