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. v4 is about rebasing on top of v5.7-rc1 * split arm and arm64 changes as there is no KVM host on arm anymore * update powerpc patches to reflect its recent changes in page table handling 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+ Geert Uytterhoeven (1): sh: fault: Modernize printing of kernel messages Mike Rapoport (13): h8300: remove usage of __ARCH_USE_5LEVEL_HACK arm: add support for folded p4d page tables arm64: add support for folded p4d page tables 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/pgtable.h | 1 - arch/arm/lib/uaccess_with_memcpy.c | 7 +- 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 | 22 +- 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 | 10 +- arch/powerpc/kvm/book3s_64_mmu_radix.c | 32 +-- arch/powerpc/lib/code-patching.c | 7 +- 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/nohash/book3e_pgtable.c | 15 +- arch/powerpc/mm/pgtable.c | 30 ++- 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 +++++++++++++++--- 81 files changed, 872 insertions(+), 520 deletions(-) delete mode 100644 include/asm-generic/5level-fixup.h delete mode 100644 include/asm-generic/pgtable-nop4d-hack.h -- 2.25.1 _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
