From: Mike Rapoport <redacted> Hi, This is a part of clean up of the page table manipulation code that aims to remove asm-generic/5level-fixup.h and asm-generic/pgtable-nop4d-hack.h There is a single patch for both arm and arm64 because doing the conversion separately would mean breaking the shared mmu bits in virt/kvm/arm. v2: * fix build error for arch/arm64/mm/dump.c * simplify p4d unfolding in arch/arm64/mm/kasan_init.c Mike Rapoport (1): arm/arm64: add support for folded p4d page tables 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 | 46 +++++- arch/arm64/mm/dump.c | 29 +++- 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 +- virt/kvm/arm/mmu.c | 209 ++++++++++++++++++++---- 27 files changed, 550 insertions(+), 143 deletions(-) -- 2.24.0 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
