I'll recheck it again on clean system, but for the record:
1. We are running 6.5-rc1 kernels.
2. PPC doesn't compile for us on -rc1 without this fix.
https://lore.kernel.org/all/20230629124500.1.I55e2f4e7903d686c4484cb23c033c6a9e1a9d4c4@changeid/
3. I didn't see anything relevant -rc1 with "git log arch/powerpc/mm/fault.c".

Do you have in mind anything specific to check?

Thanks
