Hi All, This v4 patchset supports 4 levels of tranlsation tables for ARM64. Firstly, The patchset decouples page size from level of translation tables as taking account into the comment from Catalin Marinas: http://www.spinics.net/linux/lists/arm-kernel/msg319552.html Then, it implements 4 levels of translation tables for native, HYP and stage2 sides. All ARMv8 and ARMv7 related changes are validated with FastModels+kvmtool and A15+QEMU, respectively. Changes since v1: - fixed unmatched data types as per Steve's comment - removed unnecessary #ifdef in arch/arm64/mm/* as per Steve's comment - revised create_pgd_entry to deal with PUD entry as per Steve's comment - introduced a macro for initial memblock limit as per Steve's comment - dropped "Fix line length exceeding 80 characters" patch as per Marc's comment - removed unnecessary #ifdef in arch/arm/kvm/mmu.c as per Marc's comment - added a macro for a number of objects of as per Marc's comment Changes since v2: - revised some macros in a generic way as per Marc's comment - added a 2 level option for kvm mmu cache allocation as per Marc's comment Changes since v3: - added #ifdef to decide swapper and idmap size as per Steve's comment - introduced Steve's create_pgd_entry Jungseok Lee (7): arm64: Use pr_* instead of printk arm64: Decouple page size from level of translation tables arm64: Introduce a kernel configuration option for VA_BITS arm64: Add a description on 48-bit address space with 4KB pages arm64: Add 4 levels of page tables definition with 4KB pages arm64: mm: Implement 4 levels of translation tables arm64: KVM: Implement 4 levels of translation tables for HYP and stage2 Documentation/arm64/memory.txt | 59 +++++++++-- arch/arm/include/asm/kvm_mmu.h | 10 ++ arch/arm/kvm/mmu.c | 88 ++++++++++++++--- arch/arm64/Kconfig | 51 +++++++++- arch/arm64/include/asm/kvm_arm.h | 34 +++++-- arch/arm64/include/asm/kvm_mmu.h | 12 +++ arch/arm64/include/asm/memblock.h | 6 ++ arch/arm64/include/asm/memory.h | 6 +- arch/arm64/include/asm/page.h | 6 +- arch/arm64/include/asm/pgalloc.h | 24 ++++- arch/arm64/include/asm/pgtable-4level-hwdef.h | 50 ++++++++++ arch/arm64/include/asm/pgtable-4level-types.h | 71 +++++++++++++ arch/arm64/include/asm/pgtable-hwdef.h | 8 +- arch/arm64/include/asm/pgtable.h | 53 +++++++++- arch/arm64/include/asm/tlb.h | 11 ++- arch/arm64/kernel/head.S | 46 +++++++-- arch/arm64/kernel/traps.c | 19 ++-- arch/arm64/mm/fault.c | 1 + arch/arm64/mm/mmu.c | 16 ++- 19 files changed, 508 insertions(+), 63 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
