From: Mike Rapoport <rppt@linux.ibm.com> Hi, These patches convert several architectures to use page table folding and remove __ARCH_HAS_5LEVEL_HACK along with include/asm-generic/5level-fixup.h and include/asm-generic/pgtable-nop4d-hack.h. With that we'll have a single and consistent way of dealing with page table folding instead of a mix of three existing options. The changes are mostly about mechanical replacement of pgd accessors with p4d ones and the addition of higher levels to page table traversals. v3: * add Christophe's patch that removes ppc32 get_pteptr() * reduce amount of upper layer walks in powerpc v2: * collect per-arch patches into a single set * include Geert's update of 'sh' printing messages * rebase on v5.6-rc1+ Christophe Leroy (1): powerpc/32: drop get_pteptr() Geert Uytterhoeven (1): sh: fault: Modernize printing of kernel messages Mike Rapoport (12): arm/arm64: add support for folded p4d page tables h8300: remove usage of __ARCH_USE_5LEVEL_HACK hexagon: remove __ARCH_USE_5LEVEL_HACK ia64: add support for folded p4d page tables nios2: add support for folded p4d page tables openrisc: add support for folded p4d page tables powerpc: add support for folded p4d page tables sh: drop __pXd_offset() macros that duplicate pXd_index() ones sh: add support for folded p4d page tables unicore32: remove __ARCH_USE_5LEVEL_HACK asm-generic: remove pgtable-nop4d-hack.h mm: remove __ARCH_HAS_5LEVEL_HACK and include/asm-generic/5level-fixup.h arch/arm/include/asm/kvm_mmu.h | 5 +- arch/arm/include/asm/pgtable.h | 1 - arch/arm/include/asm/stage2_pgtable.h | 15 +- arch/arm/lib/uaccess_with_memcpy.c | 9 +- arch/arm/mach-sa1100/assabet.c | 2 +- arch/arm/mm/dump.c | 29 ++- arch/arm/mm/fault-armv.c | 7 +- arch/arm/mm/fault.c | 28 ++- arch/arm/mm/idmap.c | 3 +- arch/arm/mm/init.c | 2 +- arch/arm/mm/ioremap.c | 12 +- arch/arm/mm/mm.h | 2 +- arch/arm/mm/mmu.c | 35 ++- arch/arm/mm/pgd.c | 40 +++- arch/arm64/include/asm/kvm_mmu.h | 10 +- arch/arm64/include/asm/pgalloc.h | 10 +- arch/arm64/include/asm/pgtable-types.h | 5 +- arch/arm64/include/asm/pgtable.h | 37 ++-- arch/arm64/include/asm/stage2_pgtable.h | 48 +++- arch/arm64/kernel/hibernate.c | 44 +++- arch/arm64/mm/fault.c | 9 +- arch/arm64/mm/hugetlbpage.c | 15 +- arch/arm64/mm/kasan_init.c | 26 ++- arch/arm64/mm/mmu.c | 52 +++-- arch/arm64/mm/pageattr.c | 7 +- arch/h8300/include/asm/pgtable.h | 1 - arch/hexagon/include/asm/fixmap.h | 4 +- arch/hexagon/include/asm/pgtable.h | 1 - arch/ia64/include/asm/pgalloc.h | 4 +- arch/ia64/include/asm/pgtable.h | 17 +- arch/ia64/mm/fault.c | 7 +- arch/ia64/mm/hugetlbpage.c | 18 +- arch/ia64/mm/init.c | 28 ++- arch/nios2/include/asm/pgtable.h | 3 +- arch/nios2/mm/fault.c | 9 +- arch/nios2/mm/ioremap.c | 6 +- arch/openrisc/include/asm/pgtable.h | 1 - arch/openrisc/mm/fault.c | 10 +- arch/openrisc/mm/init.c | 4 +- arch/powerpc/include/asm/book3s/32/pgtable.h | 1 - arch/powerpc/include/asm/book3s/64/hash.h | 4 +- arch/powerpc/include/asm/book3s/64/pgalloc.h | 4 +- arch/powerpc/include/asm/book3s/64/pgtable.h | 60 ++--- arch/powerpc/include/asm/book3s/64/radix.h | 6 +- arch/powerpc/include/asm/nohash/32/pgtable.h | 1 - arch/powerpc/include/asm/nohash/64/pgalloc.h | 2 +- .../include/asm/nohash/64/pgtable-4k.h | 32 +-- arch/powerpc/include/asm/nohash/64/pgtable.h | 6 +- arch/powerpc/include/asm/pgtable.h | 6 +- arch/powerpc/kvm/book3s_64_mmu_radix.c | 30 ++- arch/powerpc/lib/code-patching.c | 7 +- arch/powerpc/mm/book3s32/mmu.c | 2 +- arch/powerpc/mm/book3s32/tlb.c | 4 +- arch/powerpc/mm/book3s64/hash_pgtable.c | 4 +- arch/powerpc/mm/book3s64/radix_pgtable.c | 26 ++- arch/powerpc/mm/book3s64/subpage_prot.c | 6 +- arch/powerpc/mm/hugetlbpage.c | 28 ++- arch/powerpc/mm/kasan/kasan_init_32.c | 8 +- arch/powerpc/mm/mem.c | 4 +- arch/powerpc/mm/nohash/40x.c | 4 +- arch/powerpc/mm/nohash/book3e_pgtable.c | 15 +- arch/powerpc/mm/pgtable.c | 30 ++- arch/powerpc/mm/pgtable_32.c | 45 +--- arch/powerpc/mm/pgtable_64.c | 10 +- arch/powerpc/mm/ptdump/hashpagetable.c | 20 +- arch/powerpc/mm/ptdump/ptdump.c | 14 +- arch/powerpc/xmon/xmon.c | 18 +- arch/sh/include/asm/pgtable-2level.h | 1 - arch/sh/include/asm/pgtable-3level.h | 1 - arch/sh/include/asm/pgtable_32.h | 5 +- arch/sh/include/asm/pgtable_64.h | 5 +- arch/sh/kernel/io_trapped.c | 7 +- arch/sh/mm/cache-sh4.c | 4 +- arch/sh/mm/cache-sh5.c | 7 +- arch/sh/mm/fault.c | 65 ++++-- arch/sh/mm/hugetlbpage.c | 28 ++- arch/sh/mm/init.c | 15 +- arch/sh/mm/kmap.c | 2 +- arch/sh/mm/tlbex_32.c | 6 +- arch/sh/mm/tlbex_64.c | 7 +- arch/unicore32/include/asm/pgtable.h | 1 - arch/unicore32/kernel/hibernate.c | 4 +- include/asm-generic/5level-fixup.h | 58 ----- include/asm-generic/pgtable-nop4d-hack.h | 64 ------ include/asm-generic/pgtable-nopud.h | 4 - include/linux/mm.h | 6 - mm/kasan/init.c | 11 - mm/memory.c | 8 - virt/kvm/arm/mmu.c | 209 +++++++++++++++--- 89 files changed, 917 insertions(+), 564 deletions(-) delete mode 100644 include/asm-generic/5level-fixup.h delete mode 100644 include/asm-generic/pgtable-nop4d-hack.h
