No, the patch does not create local_cpus
Do you have local_cpus and local_cpulist attributes as well?
User-space tools such as hwloc use those for binding near I/O devices,
although I guess we could have some CPU-less NVDIMM NUMA nodes?

Add support of sysfs 'numa_node' to I/O-related NVDIMM devices
under /sys/bus/nd/devices, regionN, namespaceN.0, and bttN.
When bttN is not set up, its numa_node returns -1 (NUMA_NO_NODE).
An example of numa_node values on a 2-socket system with a single
NVDIMM range on each socket is shown below.
