From: "Mike Rapoport (IBM)" <rppt@xxxxxxxxxx> Every architecture that supports FLATMEM memory model defines its own version of pfn_valid() that essentially compares a pfn to max_mapnr. Use mips/powerpc version implemented as static inline as a generic implementation of pfn_valid() and drop its per-architecture definitions Signed-off-by: Mike Rapoport (IBM) <rppt@xxxxxxxxxx> --- arch/alpha/include/asm/page.h | 4 ---- arch/arc/include/asm/page.h | 1 - arch/csky/include/asm/page.h | 1 - arch/hexagon/include/asm/page.h | 1 - arch/ia64/include/asm/page.h | 4 ---- arch/loongarch/include/asm/page.h | 13 ------------- arch/m68k/include/asm/page_no.h | 2 -- arch/microblaze/include/asm/page.h | 1 - arch/mips/include/asm/page.h | 13 ------------- arch/nios2/include/asm/page.h | 9 --------- arch/openrisc/include/asm/page.h | 2 -- arch/parisc/include/asm/page.h | 4 ---- arch/powerpc/include/asm/page.h | 9 --------- arch/riscv/include/asm/page.h | 5 ----- arch/sh/include/asm/page.h | 3 --- arch/sparc/include/asm/page_32.h | 1 - arch/um/include/asm/page.h | 1 - arch/x86/include/asm/page_32.h | 4 ---- arch/x86/include/asm/page_64.h | 4 ---- arch/xtensa/include/asm/page.h | 2 -- include/asm-generic/memory_model.h | 12 ++++++++++++ include/asm-generic/page.h | 2 -- 22 files changed, 12 insertions(+), 86 deletions(-)
