ACPI material for v4.7-rc1 

- In-kernel ACPICA code update to the upstream release 20160422
    adding support for ACPI 6.1 along with some previously missing
    bits of ACPI 6.0 support, making a fair amount of fixes and
    cleanups and reducing divergences between the upstream ACPICA
    and the in-kernel code (Bob Moore, Lv Zheng, Al Stone, Aleksey
    Makarov, Will Miles).
 
  - ACPI Generic Event Device (GED) support and a fix for it (Sinan Kaya,
    Paul Gortmaker).
 
  - INT3406 thermal driver for display thermal management and ACPI
    backlight support code reorganization related to it (Aaron Lu,
    Arnd Bergmann).
 
  - Support for exporting the value returned by the _HRV (hardware
    revision) ACPI object via sysfs (Betty Dall).
 
  - Removal of the EXPERT dependency for ACPI on ARM64 (Mark Brown).
 
  - Rework of the handling of ACPI _OSI mechanism allowing the
    _OSI("Darwin") support to be overridden from the kernel command
    line among other things (Lv Zheng, Chen Yu).
 
  - Rework of the ACPI tables override mechanism to prepare it for
    the introduction of overlays support going forward (Lv Zheng,
    Rafael Wysocki).
 
  - Fixes related to the ECDT support and module-level execution
    of AML (Lv Zheng).
 
  - ACPI PCI interrupts management update to make it work better on
    ARM64 mostly (Sinan Kaya).
 
  - ACPI SRAT handling update to make the code process all entires
    in the table order regardless of the entry type (Lukasz Anaczkowski).
 
  - EFI power off support for full-hardware ACPI platforms that don't
    support ACPI S5 (Chen Yu).
 
  - Fixes and cleanups related to the ACPI core's sysfs interface
    (Dan Carpenter, Betty Dall).
 
  - acpi_dev_present() API rework to reduce possible confusion related
    to it (Lukas Wunner).
 
  - Removal of CLK_IS_ROOT from two ACPI drivers (Stephen Boyd).

Merge tag 'acpi-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "The new features here are ACPI 6.1 support (and some previously
  missing bits of ACPI 6.0 support) in ACPICA and two new drivers, a
  driver for the ACPI Generic Event Device (GED) feature introduced by
  ACPI 6.1 and the INT3406 thermal driver for display thermal
  management.  Also the value returned by the _HRV (hardware revision)
  ACPI object will be exported to user space via sysfs now.

  In addition to that, ACPI on ARM64 will not depend on EXPERT any more.

  The rest is mostly fixes and cleanups and some code reorganization.

@ -9,12 +9,14 @@ Overriding ACPI tables via initrd
1) What is this about
---------------------
If the ACPI_INITRD_TABLE_OVERRIDE compile option is true, it is possible to
override nearly any ACPI table provided by the BIOS with an instrumented,
modified one.
If the ACPI_TABLE_UPGRADE compile option is true, it is possible to
upgrade the ACPI execution environment that is defined by the ACPI tables
via upgrading the ACPI tables provided by the BIOS with an instrumented,
modified, more recent version one, or installing brand new ACPI tables.
For a full list of ACPI tables that can be overridden, take a look at
the char *table_sigs[MAX_ACPI_SIGNATURE]; definition in drivers/acpi/osl.c
For a full list of ACPI tables that can be upgraded/installed, take a look
at the char *table_sigs[MAX_ACPI_SIGNATURE]; definition in

All ACPI tables iasl (Intel's ACPI compiler and disassembler) knows should
be overridable, except:
- ACPI_SIG_RSDP (has a signature of 6 bytes)

2) What is this for
-------------------
Please keep in mind that this is a debug option.
ACPI tables should not get overridden for productive use.
If BIOS ACPI tables are overridden the kernel will get tainted with the
TAINT_OVERRIDDEN_ACPI_TABLE flag.
Complain to your platform/BIOS vendor if you find a bug which is so sever
that a workaround is not accepted in the Linux kernel.
Complain to your platform/BIOS vendor if you find a bug which is so severe
that a workaround is not accepted in the Linux kernel. And this facility
allows you to upgrade the buggy tables before your platform/BIOS vendor
releases an upgraded BIOS binary.
Still, it can and should be enabled in any kernel, because:
- There is no functional change with not instrumented initrds
- It provides a powerful feature to easily debug and test ACPI BIOS table
compatibility with the Linux kernel.
This facility can be used by platform/BIOS vendors to provide a Linux
compatible environment without modifying the underlying platform firmware.
This facility also provides a powerful feature to easily debug and test
ACPI BIOS table compatibility with the Linux kernel by modifying old
platform provided ACPI tables or inserting new ACPI tables.
