Ok, but that's not in mainline, not in the arm64 tree and not in Christoph's
branch. I don't want to pull in random cherry-picks that are already in
-next via some other means (looks like this is via -tip?).

If the conflicts are trivial, just base on uuid-types (which I've merged
into the arm64 for-next/ras-apei branch). If they're not trivial, then you
need to co-ordinate better with other developers and I think this will have
to wait another release.
