Subject[PATCH v9 00/15] ARM: Add support for the Large Physical Address Extensions
Date
This is version 9 of the set of patches adding support for the Large
Physical Address Extensions on the ARM architecture (available with the
Cortex-A15 and Cortex-A7 processors).

This patch set against 3.2-rc1 is available on this branch:

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

The patch set also includes Russell's nopud patch with an additional
fix-up to be reviewed (they are not in mainline yet but LPAE depends on
them).


Changelog (from v8, updates following review):

- Removed the ATAG_MEM64 patch.
- Removed the different PMD_SECT_XN definition for asm.
- proc-v7.S fixes for SMP/UP instructions pairing.
- Removed references to PHYS_OFFSET in proc-v7.S and added comment about
VMSPLIT_1G.
- pr_fmt() definition removed from idmap.c.
- ARCH_DMA_ADDR_T_64BIT now defaults to false without any dependencies.
Platforms should select this explicitly.
- Reordered the nopud fixup with Russell's nopud patch.

Known issues:

- idmap_add_pmd() still cannot be called in an atomic context but the
kexec patches re-implement the setup_mm_for_reboot() function and it
no longer calls identity_mapping_add().


Catalin Marinas (12):
ARM: pgtable: Fix compiler warning in ioremap.c introduced by nopud
ARM: LPAE: Move page table maintenance macros to pgtable-2level.h
ARM: LPAE: Move the FSR definitions to separate files
ARM: LPAE: Factor out classic-MMU specific code into proc-v7-2level.S
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

Russell King (1):
ARM: pgtable: switch to use pgtable-nopud.h

Will Deacon (2):
ARM: LPAE: add ISBs around MMU enabling code
ARM: LPAE: mark memory banks with start > ULONG_MAX as highmem
