    Subject[RFC 00/23] Introducing the TI Keystone platform
    Date
    TI's scalable KeyStone II architecture includes support for both TMS320C66x
    floating point DSPs and ARM Cortex-A15 clusters, for a mixture of up to 32
    cores per SoC. The solution is optimized around a high performance chip
    interconnect and a rich set of on chip peripherals. Please refer [1] for
    initial technical documentation on these devices.

    This patch series provides a basic Linux port for these devices, including
    support for SMP, and LPAE boot. A majority of the patches in this series are
    related to LPAE functionality, imposed by the device architecture which has
    system memory mapped at an address above the 4G 32-bit addressable limit.

    This patch series is based on the v3.5 kernel with the smp_ops patch set
    applied on top. This series is being posted to elicit early feedback, and so
    that some of these fixes may get incorporated early on into the kernel code.

    Cyril Chemparathy (17):
    ARM: LPAE: use signed arithmetic for mask definitions
    ARM: LPAE: use phys_addr_t on virt <--> phys conversion
    ARM: LPAE: use phys_addr_t for membank size
    ARM: LPAE: use 64-bit pgd physical address in switch_mm()
    ARM: LPAE: use 64-bit accessors for TTBR registers
    ARM: mm: use physical addresses in highmem sanity checks
    ARM: mm: cleanup checks for membank overlap with vmalloc area
    ARM: mm: clean up membank size limit checks
    ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem
    ARM: LPAE: factor out T1SZ and TTBR1 computations
    ARM: LPAE: allow proc override of TTB setup
    ARM: LPAE: accomodate >32-bit addresses for page table base
    ARM: add machine desc hook for early memory/paging initialization
    drivers: cma: fix addressing on PAE machines
    ARM: keystone: introducing TI Keystone platform
    ARM: keystone: enable SMP on Keystone machines
    ARM: keystone: add switch over to high physical address range

    Vitaly Andrianov (6):
    ARM: LPAE: disable phys-to-virt patching on PAE systems
    ARM: LPAE: use phys_addr_t in alloc_init_pud()
    ARM: LPAE: use phys_addr_t in free_memmap()
    ARM: LPAE: use phys_addr_t for initrd location and size
    ARM: add virt_to_idmap for interconnect aliasing
    mm: bootmem: use phys_addr_t for physical addresses
