Hi Memory hotplug maintainers,

Sorry to CC, but could you help to review this Intel TDX (Trusted Domain
Extensions) patch, since it is related to memory hotplug (not modifying any
common memory hotplug directly, though)?  Dave suggested it's better to get
memory hotplug guys to help to review sooner than later.

This whole series already has linux-mm@xxxxxxxxx in the CC list.  Thanks for
your time.

Hi,

I remember discussing that part (notifier) already and it looked good tome. No objection from my side.
