This fix a few issues when I tried to enable pmem as RAM device on arm64.
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.
Changes: v2: - Drop unneccessary patch to harden try_offline_node - Use new solution(by David) to fix dev->target_node=-1 during probing - Refine the mem_hotplug_begin/done patch
v1: https://lkml.org/lkml/2020/7/5/381
Jia He (3): arm64/numa: export memory_add_physaddr_to_nid as EXPORT_SYMBOL_GPL device-dax: use fallback nid when numa_node is invalid mm/memory_hotplug: fix unpaired mem_hotplug_begin/done
