Re: [PATCH v1 3/3] powerpc: fix node_possible_map limitations

Can you make the subject a bit more descriptive?

Currently this prevents node hotplug, so it's required that we remove it
to support that IIUIC.

We've fixed the memory hotplug issue with memcg, hence
this work around should not be required.

Fixes: commit 3af229f2071f
("powerpc/numa: Reset node_possible_map to only node_online_map")

I don't think Fixes is right here, that commit wasn't buggy, it was just
a workaround for the code at that time.

Just say "This is a revert of commit 3af229f2071f ("powerpc/numa: Reset
node_possible_map to only node_online_map")".

Otherwise LGTM to go via mm.
