Hi Linus,

Please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-4.8-rc1

to receive core ACPI code updates for v4.8-rc1 with top-most commit
54d0b14ad7cc4ff3c710f092a93638f359c1b14b

Merge branches 'acpi-drivers', 'acpi-misc' and 'acpi-tools'

on top of commit 523d939ef98fd712632d93a5a2b588e477a7565e

Linux 4.7

The new feaures here are the support for ACPI overlays (allowing
ACPI tables to be loaded at any time from EFI variables or via
configfs) and the LPI (Low-Power Idle) support. Also notable
is the ACPI-based NUMA support for ARM64.

Apart from that we have two new drivers, for the DPTF (Dynamic
Power and Thermal Framework) power participant device and for the
Intel Broxton WhiskeyCove PMIC, some more PMIC-related changes,
support for the Boot Error Record Table (BERT) in APEI and support
for platform-initiated graceful shutdown.

Plus two new pieces of documentation and usual assorted fixes and
cleanups in quite a few places.

Specifics:

- Support for ACPI SSDT overlays allowing Secondary System
Description Tables (SSDTs) to be loaded at any time from EFI
variables or via configfs (Octavian Purdila, Mika Westerberg).

- Support for the ACPI LPI (Low-Power Idle) feature introduced in
ACPI 6.0 and allowing processor idle states to be represented in
ACPI tables in a hierarchical way (with the help of Processor
Container objects) and support for ACPI idle states management
on ARM64, based on LPI (Sudeep Holla).

- General improvements of ACPI support for NUMA and ARM64 support
for ACPI-based NUMA (Hanjun Guo, David Daney, Robert Richter).

- General improvements of the ACPI table upgrade mechanism and
ARM64 support for that feature (Aleksey Makarov, Jon Masters).

- Support for the Boot Error Record Table (BERT) in APEI and
improvements of kernel messages printed by the error injection
code (Huang Ying, Borislav Petkov).

- New driver for the Intel Broxton WhiskeyCove PMIC operation
region and support for the REGS operation region on Broxton,
PMIC code cleanups (Bin Gao, Felipe Balbi, Paul Gortmaker).

- New driver for the power participant device which is part of the
Dynamic Power and Thermal Framework (DPTF) and DPTF-related code
reorganization (Srinivas Pandruvada).

- Support for the platform-initiated graceful shutdown feature
introduced in ACPI 6.1 (Prashanth Prakash).

- ACPI button driver update related to lid input events generated
automatically on initialization and system resume that have been
problematic for some time (Lv Zheng).

- ACPI EC driver cleanups (Lv Zheng).

- Documentation of the ACPICA release automation process and the
in-kernel ACPI AML debugger (Lv Zheng).

- New blacklist entry and two fixes for the ACPI backlight driver
(Alex Hung, Arvind Yadav, Ralf Gerbig).

- Cleanups of the ACPI pci_slot driver (Joe Perches, Paul Gortmaker).

- ACPI CPPC code changes to make it more robust against possible
defects in ACPI tables and new symbol definitions for PCC (Hoan
Tran).

- System reboot code modification to execute the ACPI _PTS (Prepare
To Sleep) method in addition to _TTS (Ocean He).

- ACPICA-related change to carry out lock ordering checks in ACPICA
if ACPICA debug is enabled in the kernel (Lv Zheng).

- Assorted minor fixes and cleanups (Andy Shevchenko, Baoquan He,
Bhaktipriya Shridhar, Paul Gortmaker, Rafael Wysocki).

Thanks!
