Use mips/powerpc version implemented as static inline as a generic implementation of pfn_valid() and drop its per-architecture definitions v2: * fix build on ARM and xtensa * add Acked- and Reviewed-by, thanks everybody v1: https://lore.kernel.org/all/20230125190757.22555-1-rppt@kernel.org Mike Rapoport (IBM) (4): arm: include asm-generic/memory_model.h from page.h rather than memory.h m68k: use asm-generic/memory_model.h for both MMU and !MMU mips: drop definition of pfn_valid() for DISCONTIGMEM mm, arch: add generic implementation of pfn_valid() for FLATMEM arch/alpha/include/asm/page.h | 4 ---- arch/arc/include/asm/page.h | 1 - arch/arm/include/asm/memory.h | 2 -- arch/arm/include/asm/page.h | 2 ++ 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.h | 6 +----- arch/m68k/include/asm/page_mm.h | 1 - arch/m68k/include/asm/page_no.h | 4 ---- arch/microblaze/include/asm/page.h | 1 - arch/mips/include/asm/page.h | 28 ---------------------------- 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 | 4 ++-- include/asm-generic/memory_model.h | 12 ++++++++++++ include/asm-generic/page.h | 2 -- 26 files changed, 17 insertions(+), 111 deletions(-) base-commit: 2241ab53cbb5cdb08a6b2d4688feb13971058f65 -- 2.35.1 _______________________________________________ linux-um mailing list linux-um@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-um
