No worries, it needs to be rebased on David's "mm/memory_hotplug: Factor out memory block device handling" series which puts it firmly in v5.3 territory.

If I've done my job right this series should be irrelevant to Documentation/admin-guide/mm/memory-hotplug.rst. The subsection capability is strictly limited to arch_add_memory() users that never online the memory, i.e. only ZONE_DEVICE / devm_memremap_pages() users. So this isn't "memory-hotplug" as much as it is "support for subsection vmemmap management".

This looks more fitting and should probably include a paragraph on the general ZONE_DEVICE / devm_memremap_pages() use case.
