LPAE comes with a 3-level page table format (compared to 2-level for the classic one), allowing up to 40-bit physical address space. The ARM LPAE documentation is available from (free registration needed): http://infocenter.arm.com/help/topic/com.arm.doc.ddi0406b_virtualization_extns/index.html The full set of patches on top of linux-next (LPAE, support for an emulated Versatile Express with Cortex-A15 tile and generic timers) is available on this branch: git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-2.6-cm.git arm-lpae-next Changelog: - Rebased on top of linux-next 20110503. - Using pgtable-nopud.h (following Russell's patch for the classic page table format). - Other fixes related to the nopud and v2p changes (mainly idmap). - The SMP support patch was dropped and a more generic variant added that makes TTBR1 always point to swapper_pg_dir on ARMv7. - Some of the previous patches already merged into mainline. Catalin Marinas (15): ARM: LPAE: Use long long printk format for displaying the pud ARM: LPAE: Use unsigned long for __phys_to_virt and __virt_to_phys ARM: LPAE: Make TTBR1 always point to swapper_pg_dir on ARMv7 ARM: LPAE: Use PMD_(SHIFT|SIZE|MASK) instead of PGDIR_* ARM: LPAE: Factor out 2-level page table definitions into separate files ARM: LPAE: Add (pte|pmd|pgd|pgprot)val_t type definitions as u32 ARM: LPAE: Use a mask for physical addresses in page table entries ARM: LPAE: Introduce the 3-level page table format definitions ARM: LPAE: Page table maintenance for the 3-level format ARM: LPAE: MMU setup for the 3-level page table format ARM: LPAE: Add fault handling support ARM: LPAE: Add context switching support ARM: LPAE: Add identity mapping support for the 3-level page table format ARM: LPAE: Add support for cpu_v7_do_(suspend|resume) ARM: LPAE: Add the Kconfig entries Will Deacon (4): ARM: LPAE: add ISBs around MMU enabling code ARM: LPAE: Use generic dma_addr_t type definition ARM: LPAE: mark memory banks with start > ULONG_MAX as highmem ARM: LPAE: add support for ATAG_MEM64 arch/arm/Kconfig | 2 +- arch/arm/include/asm/assembler.h | 11 ++ arch/arm/include/asm/memory.h | 4 +- arch/arm/include/asm/page.h | 44 +----- arch/arm/include/asm/pgalloc.h | 28 ++++- arch/arm/include/asm/pgtable-2level-hwdef.h | 93 ++++++++++++ arch/arm/include/asm/pgtable-2level-types.h | 67 +++++++++ arch/arm/include/asm/pgtable-2level.h | 143 ++++++++++++++++++ arch/arm/include/asm/pgtable-3level-hwdef.h | 81 ++++++++++ arch/arm/include/asm/pgtable-3level-types.h | 68 +++++++++ arch/arm/include/asm/pgtable-3level.h | 106 ++++++++++++++ arch/arm/include/asm/pgtable-hwdef.h | 81 +---------- arch/arm/include/asm/pgtable.h | 211 +++++++++------------------ arch/arm/include/asm/proc-fns.h | 25 +++ arch/arm/include/asm/setup.h | 10 +- arch/arm/include/asm/smp.h | 1 + arch/arm/include/asm/tlbflush.h | 4 +- arch/arm/include/asm/types.h | 11 +-- arch/arm/kernel/compat.c | 4 +- arch/arm/kernel/head.S | 126 +++++++++++----- arch/arm/kernel/module.c | 2 +- arch/arm/kernel/setup.c | 12 ++- arch/arm/kernel/smp.c | 1 + arch/arm/mm/Kconfig | 13 ++ arch/arm/mm/alignment.c | 8 +- arch/arm/mm/context.c | 19 ++- arch/arm/mm/dma-mapping.c | 6 +- arch/arm/mm/fault.c | 82 ++++++++++- arch/arm/mm/idmap.c | 36 +++++- arch/arm/mm/ioremap.c | 8 +- arch/arm/mm/mm.h | 4 +- arch/arm/mm/mmu.c | 51 +++++-- arch/arm/mm/pgd.c | 51 ++++++- arch/arm/mm/proc-macros.S | 5 +- arch/arm/mm/proc-v7.S | 152 +++++++++++++++++-- 35 files changed, 1207 insertions(+), 363 deletions(-) create mode 100644 arch/arm/include/asm/pgtable-2level-hwdef.h create mode 100644 arch/arm/include/asm/pgtable-2level-types.h create mode 100644 arch/arm/include/asm/pgtable-2level.h create mode 100644 arch/arm/include/asm/pgtable-3level-hwdef.h create mode 100644 arch/arm/include/asm/pgtable-3level-types.h create mode 100644 arch/arm/include/asm/pgtable-3level.h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
