Subject[PATCH v5 00/19] 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 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

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
