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
