Subject[PATCH 0/1] fix pmem RAM device when nid is NUMA_NO_NODE
I once sent out the preparatory patches [1] but I dropped the last patch
of using fallback nid with memory_add_physaddr_to_nid() due to some

After phys_addr_to_target_node() and memory_add_physaddr_to_nid() are
stable now, it's time to fix the original bug on arm64 now.

Compared with the last version [2], this version rebases the patch to
latest v5.14-rc3 (s/kmem_start/range.start)

Tested on ThunderX2 host/qemu "-M virt" guest with a nvdimm device. The
memblocks from the dax pmem device can be either hot-added or hot-removed
on arm64 guest. Also passed the compilation test on x86.
