FWIW, you can add my Acked-by on your repost Michal.

I reviewed your patches and tested them against that PPC crash on boot 
described at https://lore.kernel.org/all/YdxoXhTqCmVrT0R5@optiplex-fbsd/

Everything has worked like a charm, AFAICT.

Thank you for letting me know about these patches, and thanks for
working on them as a follow-up to that problem reported by Nico.
