Uh yeah so in v3 I did not depend on this patch, I just went straight to
creating __folio_alloc_mpol_noprof() here:

https://lore.kernel.org/all/20260726-page_alloc-unmapped-v3-25-6f5729aa9832@xxxxxxxxxx/

So yeah I'd say we can just drop this controversial patch and move
forwards with the other two?
