Grep shows __pgd() definitions for both of them. Is it for specific > config? For ARM32 it's defined only for 3-lelel page tables, i.e with LPAE on. For IA64 it's defined for !STRICT_MM_TYPECHECKS which is even not a config option, but a define in arch/ia64/include/asm/page.h > -- > Kirill A. Shutemov -- Sincerely yours, Mike.
