Commit 31168f03 ("mips: drop __pXd_offset() macros that duplicate pXd_index() ones") is correct that pud_index() & __pud_offset() are the same when pud_index() is actually provided, however it does not take into account the __PAGETABLE_PUD_FOLDED case. This has broken MIPS KVM compilation because it relied on availability of pud_index(). Define pud_index() regardless of page table folded. It will evaluate to actual index for 4-level pagetables and to 0 for folded PUD level. Link: https://lore.kernel.org/lkml/20200331154749.5457-1-pbonzini@redhat.comReported-by:
