    Subject[PATCH v3 00/20] ARM: Add support for the Large Physical Address Extensions
    Date
    Hi,

    This set of patches adds support for the Large Physical Extensions on
    the ARM architecture (available with the Cortex-A15 processor). 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 (kernel fixes, LPAE and support for an emulated
    Versatile Express with Cortex-A15 tile) is available on this branch:

    git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-2.6-cm.git arm-lpae

    Changelog:

    - Fixed printk formatting and reordered patches to avoid compiler warning when
    only part of the series is applied.
    - Renamed PTE_WORDS to PTE_SHIFT in arch/arm/kernel/head.S.
    - Fixed typo in Kconfig.


    Catalin Marinas (13):
    ARM: LPAE: Use PMD_(SHIFT|SIZE|MASK) instead of PGDIR_*
    ARM: LPAE: Factor out 2-level page table definitions into separate
    files
    ARM: LPAE: Do not assume Linux PTEs are always at PTRS_PER_PTE offset
    ARM: LPAE: Introduce L_PTE_NOEXEC and L_PTE_NOWRITE
    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: Change setup_mm_for_reboot() to work with LPAE
    ARM: LPAE: Remove the FIRST_USER_PGD_NR and USER_PTRS_PER_PGD
    definitions
    ARM: LPAE: Add fault handling support
    ARM: LPAE: Add context switching support
    ARM: LPAE: Add SMP support for the 3-level page table format
    ARM: LPAE: Add the Kconfig entries

    Will Deacon (7):
    ARM: LPAE: use long long format when printing physical addresses and
    ptes
    ARM: LPAE: use u32 instead of unsigned long for 32-bit ptes
    ARM: LPAE: use phys_addr_t instead of unsigned long for physical
    addresses
    ARM: LPAE: Use generic dma_addr_t type definition
    ARM: LPAE: mark memory banks with start > ULONG_MAX as highmem
    ARM: LPAE: use phys_addr_t for physical start address in early_mem
    ARM: LPAE: add support for ATAG_MEM64
