The main change in this submission is to enable the fast mremap optimization on a per-architecture basis to prevent possible issues with architectures that may not behave well with such change. x86: select HAVE_MOVE_PMD for faster mremap (v1) arm64: select HAVE_MOVE_PMD for faster mremap (v1) mm: speed up mremap by 500x on large regions (v2) v1->v2: Added support for per-arch enablement (Kirill Shutemov) treewide: remove unused address argument from pte_alloc functions (v2) v1->v2: fix arch/um/ prototype which was missed in v1 (Anton Ivanov) update changelog with manual fixups for m68k and microblaze. Joel Fernandes (Google) (4): treewide: remove unused address argument from pte_alloc functions (v2) mm: speed up mremap by 500x on large regions (v2) arm64: select HAVE_MOVE_PMD for faster mremap (v1) x86: select HAVE_MOVE_PMD for faster mremap (v1) arch/Kconfig | 5 ++ arch/alpha/include/asm/pgalloc.h | 6 +- arch/arc/include/asm/pgalloc.h | 5 +- arch/arm/include/asm/pgalloc.h | 4 +- arch/arm64/Kconfig | 1 + arch/arm64/include/asm/pgalloc.h | 4 +- arch/hexagon/include/asm/pgalloc.h | 6 +- arch/ia64/include/asm/pgalloc.h | 5 +- arch/m68k/include/asm/mcf_pgalloc.h | 8 +-- arch/m68k/include/asm/motorola_pgalloc.h | 4 +- arch/m68k/include/asm/sun3_pgalloc.h | 6 +- arch/microblaze/include/asm/pgalloc.h | 19 +----- arch/microblaze/mm/pgtable.c | 3 +- arch/mips/include/asm/pgalloc.h | 6 +- arch/nds32/include/asm/pgalloc.h | 5 +- arch/nios2/include/asm/pgalloc.h | 6 +- arch/openrisc/include/asm/pgalloc.h | 5 +- arch/openrisc/mm/ioremap.c | 3 +- arch/parisc/include/asm/pgalloc.h | 4 +- arch/powerpc/include/asm/book3s/32/pgalloc.h | 4 +- arch/powerpc/include/asm/book3s/64/pgalloc.h | 12 ++-- arch/powerpc/include/asm/nohash/32/pgalloc.h | 4 +- arch/powerpc/include/asm/nohash/64/pgalloc.h | 6 +- arch/powerpc/mm/pgtable-book3s64.c | 2 +- arch/powerpc/mm/pgtable_32.c | 4 +- arch/riscv/include/asm/pgalloc.h | 6 +- arch/s390/include/asm/pgalloc.h | 4 +- arch/sh/include/asm/pgalloc.h | 6 +- arch/sparc/include/asm/pgalloc_32.h | 5 +- arch/sparc/include/asm/pgalloc_64.h | 6 +- arch/sparc/mm/init_64.c | 6 +- arch/sparc/mm/srmmu.c | 4 +- arch/um/include/asm/pgalloc.h | 4 +- arch/um/kernel/mem.c | 4 +- arch/unicore32/include/asm/pgalloc.h | 4 +- arch/x86/Kconfig | 1 + arch/x86/include/asm/pgalloc.h | 4 +- arch/x86/mm/pgtable.c | 4 +- arch/xtensa/include/asm/pgalloc.h | 8 +-- include/linux/mm.h | 13 ++-- mm/huge_memory.c | 8 +-- mm/kasan/kasan_init.c | 2 +- mm/memory.c | 17 +++-- mm/migrate.c | 2 +- mm/mremap.c | 67 +++++++++++++++++++- mm/userfaultfd.c | 2 +- virt/kvm/arm/mmu.c | 2 +- 47 files changed, 169 insertions(+), 147 deletions(-) -- 2.19.0.605.g01d371f741-goog
