When PUD and/or PMD are folded, those functions are useless
and we now have a stub in linux/pgtable.h
OK, help me out here please. What patch does this fix?
Both this one and the x86 one from the day before fix 1cff41494b15cd82c1ec418bb5c ("mm/pgtable: add stubs for {pmd/pub}_{set/clear}_huge")
I think both the x86 fix and the arm64 fix should be squashed into that patch at the end.
I checked, the only other architecture involving pud_set_huge() and friends is powerpc, and powerpc doesn't have this problem as it only defined those for book3s/64 platforms which have 4 level page tables by definition.
Thanks
Christophe
