--- Comment #2 from Christophe Leroy (christophe.le...@csgroup.eu) ---
The bug is not in powerpc but in function pmd_basic_tests() in
mm/debug_vm_pgtable.c
(https://elixir.bootlin.com/linux/v5.13-rc1/source/mm/debug_vm_pgtable.c#L146)
pfn_pmd() should not be called before the has_transparent_hugepage()
verification.
Same problem in pmd_advanced_tests()
And there is the exact same issue with PUD tests with pfn_pud() function.
