Hey Masahiro, just pinging to see the state of this PR.

I think we are on pace to re-enable this warning.

I believe there exists only _two_ patches left still needing to go
through along with this patch:
1) https://lore.kernel.org/all/20220718050356.227647-1-hch@xxxxxx/
2) https://lore.kernel.org/all/YtnDltqEVeJQQkbW@dev-arch.thelio-3990X/
