Re: [PATCH] mm/pgtable: define pte_index so that preprocessor could recognize it

Hello Mike!

Mike Rapoport rppt@kernel.org [11. Januar 2022]:

diff --git a/include/linux/pgtable.h b/include/linux/pgtable.h index e24d2c992b11..d468efcf48f4 100644 --- a/include/linux/pgtable.h +++ b/include/linux/pgtable.h @@ -62,6 +62,7 @@ static inline unsigned long pte_index(unsigned long address) { return (address >> PAGE_SHIFT) & (PTRS_PER_PTE - 1); } +#define pte_index pte_index

Wouldn't it make sense to remove the dead CPP blocks (#ifdef pte_index) from mm/memory.c? Or is there a case were pte_index is not defined for an architecture?
