I think it should apply cleanly on any up-to-date tree provided you also apply https://lore.kernel.org/lkml/174413914101.31282.6876925851363406689.tip-bot= 2@tip-bot2 (which is on next, so it's not required if that's your tree). If that doesn't help, my base was aa94665adc28f3fdc3de2979ac1e98bae961d6ca (tag: next-20250513), I included it in 00/12 but I'm not sure what kind of tool reads that. I guess next time I should add Peter's patch to the series too to save people some headache though..
