    Subject[PATCH v7 00/16] ARM: Add support for the Large Physical Address Extensions
    Date
    Hi,

    This is version 7 of the set of patches adding support for the Large
    Physical Address Extensions on the ARM architecture (available with the
    Cortex-A15 processor). LPAE comes with a new 3-level page table format
    (compared to 2-level for the classic one), allowing up to 40-bit
    physical address space.

    This set of patches against Linux 3.1-rc1 is available on this branch:

    git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-2.6-cm.git for-next

    The full set of patches against Linux 3.0 (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


    Changelog (from v6):

    - Rebased against Linux 3.1-rc1.
    - pteval_t, pmdval_t etc. typedefs reworked for consistency.
    - __phys_to_virt/__virt_to_phys macros typecasting patch removed (an
    explicit cast to unsigned long has been added to dma_to_virt).
    - Generic dma_addr_t patch removed (already fixed upstream).

    Known issues:

    - RMK's nopud patch not in mainline yet (compiler warnings) but carried
    over in the above branches.
    - No decission on using the ISB during MMU enabling (no simple
    alternative solution).
    - The patch converting PGDIR_* to PMD_* may be further modified
    depending on the merging of the DMA coherent patches and other changes
    to prepare_page_tables() proposed by RMK.


    Catalin Marinas (13):
    ARM: LPAE: Cast the dma_addr_t argument to unsigned long in
    dma_to_virt
    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)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: Invalidate the TLB before freeing the PMD
    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 the Kconfig entries

    Will Deacon (3):
    ARM: LPAE: add ISBs around MMU enabling code
    ARM: LPAE: mark memory banks with start > ULONG_MAX as highmem
    ARM: LPAE: add support for ATAG_MEM64
