[PATCH v6 00/17] Introduce ACPI for ARM64 based on ACPI 5.1

[Hanjun Guo]

Hi,

This is the sixth version of ACPI core patches for ARM64 based on ACPI
5.1.

updates from v5:
  - fix the NULL pointer reference in cpu_get_ops() if PSCI is absent
    and NULL will passed, which found by Suravee when he was testing
    those patches on Seattle platform. I added his Tested-by for all
    those ACPI patches.

  - Rebased on 3.19-rc2 which ACPI table related patches already merged
    into 3.19 by Rafael, and remove the first patch in v5 which is not needed
    any more.

  - Add two cleanup patches to convert ACPI ID to physical ID to make the
    ACPI core looks more ARCH agnostic, those two patches were expected going
    into 3.19 but conflicted with IOAPIC hotplug patches so Rafael left them
    for 3.20.

  - updates to the doc about ACPI on ARM to address comments from Catalin,
    Timur, Ashwin. continue discussion will bw needed about this doc.

  - we did lots of work as Al pointed out in the "[RFC] ACPI on arm64 TODO List"
    thread [1], and we already make FWTS running on ARM64, thanks FuWei for doing
    that. Here is the test results for linaro leg kernel release test results:
