Subject[PATCH v2 0/3] Fix and enable pmem as RAM device on arm64
Date
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
