From: "Mike Rapoport (Microsoft)" <[email protected]> Hi, These patches cleanup handling of ZERO_PAGE() and zero_pfn. v2 changes: * add patches that cleanup zero_pfn code a bit (patches 1,2) * add a patch that caches struct page for empty_zero_page (patch 4) * use uint8_t instead of unsigned long for empty_zero_page * fix sparc64 changes in patch 3 v1: https://lore.kernel.org/all/[email protected] Mike Rapoport (Microsoft) (4): mm: don't special case !MMU for is_zero_pfn() and my_zero_pfn() mm: rename my_zero_pfn() to zero_pfn() arch, mm: consolidate empty_zero_page mm: cache struct page for empty_zero_page and return it from ZERO_PAGE() arch/alpha/include/asm/pgtable.h | 6 --- arch/arc/include/asm/pgtable.h | 3 -- arch/arc/mm/init.c | 2 - arch/arm/include/asm/pgtable.h | 9 ----- arch/arm/mm/mmu.c | 7 ---- arch/arm/mm/nommu.c | 7 ---- arch/arm64/include/asm/pgtable.h | 7 ---- arch/arm64/mm/init.c | 5 +++ arch/arm64/mm/mmu.c | 7 ---- arch/csky/include/asm/pgtable.h | 3 -- arch/csky/mm/init.c | 3 -- arch/hexagon/include/asm/pgtable.h | 6 --- arch/hexagon/kernel/head.S | 5 --- arch/hexagon/kernel/hexagon_ksyms.c | 1 - arch/loongarch/include/asm/pgtable.h | 9 ----- arch/loongarch/mm/init.c | 3 -- arch/m68k/include/asm/pgtable_mm.h | 9 ----- arch/m68k/include/asm/pgtable_no.h | 7 ---- arch/m68k/mm/init.c | 9 ----- arch/m68k/mm/mcfmmu.c | 2 - arch/m68k/mm/motorola.c | 6 --- arch/m68k/mm/sun3mmu.c | 2 - arch/microblaze/include/asm/pgtable.h | 10 ----- arch/microblaze/kernel/head.S | 4 -- arch/microblaze/kernel/microblaze_ksyms.c | 2 - arch/mips/mm/init.c | 11 +----- arch/nios2/include/asm/pgtable.h | 7 ---- arch/nios2/kernel/head.S | 10 ----- arch/nios2/kernel/nios2_ksyms.c | 1 - arch/openrisc/include/asm/pgtable.h | 4 -- arch/openrisc/kernel/head.S | 3 -- arch/openrisc/kernel/or32_ksyms.c | 1 - arch/openrisc/mm/init.c | 3 -- arch/parisc/include/asm/pgtable.h | 11 ------ arch/parisc/mm/init.c | 6 --- arch/powerpc/include/asm/pgtable.h | 6 --- arch/powerpc/mm/mem.c | 3 -- arch/riscv/include/asm/pgtable.h | 7 ---- arch/riscv/mm/init.c | 4 -- arch/s390/mm/init.c | 4 +- arch/sh/include/asm/pgtable.h | 8 ---- arch/sh/include/asm/setup.h | 3 +- arch/sh/kernel/head_32.S | 4 +- arch/sh/kernel/sh_ksyms_32.c | 1 - arch/sh/mm/init.c | 1 - arch/sparc/include/asm/pgtable_32.h | 8 ---- arch/sparc/include/asm/pgtable_64.h | 3 -- arch/sparc/include/asm/setup.h | 2 - arch/sparc/kernel/head_32.S | 7 ---- arch/sparc/mm/init_32.c | 4 -- arch/sparc/mm/init_64.c | 24 +++++------- arch/um/include/asm/pgtable.h | 9 ----- arch/um/include/shared/kern_util.h | 1 - arch/um/kernel/mem.c | 16 -------- arch/um/kernel/um_arch.c | 1 - arch/x86/include/asm/pgtable.h | 8 ---- arch/x86/kernel/head_32.S | 4 -- arch/x86/kernel/head_64.S | 7 ---- arch/x86/kvm/mmu/spte.h | 2 +- arch/xtensa/include/asm/pgtable.h | 4 -- arch/xtensa/kernel/head.S | 3 -- arch/xtensa/kernel/xtensa_ksyms.c | 2 - fs/dax.c | 2 +- fs/proc/vmcore.c | 2 +- include/linux/pgtable.h | 48 ++++++++++++++--------- mm/huge_memory.c | 2 +- mm/memory.c | 15 +------ mm/migrate.c | 2 +- mm/mm_init.c | 28 +++++++++++++ mm/userfaultfd.c | 4 +- 70 files changed, 86 insertions(+), 354 deletions(-) base-commit: 50c7f34c5c7403a12003c6759f6f6ca9a5a10872 -- 2.51.0 _______________________________________________ linux-snps-arc mailing list [email protected] http://lists.infradead.org/mailman/listinfo/linux-snps-arc
