[GIT PULL] ACPI and power management updates for v3.17-rc1

From: Rafael J. Wysocki
Date: Wed Aug 06 2014 - 15:07:40 EST

Hi Linus,

Please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-3.17-rc1

to receive ACPI and power management updates for v3.17-rc1 with
top-most commit 7ef97e0e3a0f4b02601dde384127cc85d27e46e2

Merge branches 'acpi-video', 'acpi-battery', 'acpi-processor' and 'acpi-lpss'

on top of commit 64aa90f26c06e1cb2aacfb98a7d0eccfbd6c1a91

Linux 3.16-rc7

Again, ACPICA leads the pack (47 commits), followed by cpufreq
(18 commits) and system suspend/hibernation (9 commits).

>From the new code perspective, the ACPICA update brings ACPI 5.1
to the table, including a new device configuration object called
_DSD (Device Specific Data) that will hopefully help us to operate
device properties like Device Trees do (at least to some extent)
and changes related to supporting ACPI on ARM.

Apart from that we have hibernation changes making it use radix
trees to store memory bitmaps which should speed up some operations
carried out by it quite significantly. We also have some power
management changes related to suspend-to-idle (the "freeze" sleep
state) support and more preliminary changes needed to support ACPI on
ARM (outside of ACPICA).

The rest is fixes and cleanups pretty much everywhere.

Specifics:

- ACPICA update to upstream version 20140724. That includes
ACPI 5.1 material (support for the _CCA and _DSD predefined names,
changes related to the DMAR and PCCT tables and ARM support among
other things) and cleanups related to using ACPICA's header files.
A major part of it is related to acpidump and the core code used
by that utility. Changes from Bob Moore, David E Box, Lv Zheng,
Sascha Wildner, Tomasz Nowicki, Hanjun Guo.

- Radix trees for memory bitmaps used by the hibernation core from
Joerg Roedel.

- Support for waking up the system from suspend-to-idle (also known
as the "freeze" sleep state) using ACPI-based PCI wakeup signaling
(Rafael J Wysocki).

- Fixes for issues related to ACPI button events (Rafael J Wysocki).

- New device ID for an ACPI-enumerated device included into the
Wildcat Point PCH from Jie Yang.

- ACPI video updates related to backlight handling from Hans de Goede
and Linus Torvalds.

- Preliminary changes needed to support ACPI on ARM from Hanjun Guo
and Graeme Gregory.

- ACPI PNP core cleanups from Arjun Sreedharan and Zhang Rui.

- Cleanups related to ACPI_COMPANION() and ACPI_HANDLE() macros
(Rafael J Wysocki).

- ACPI-based device hotplug cleanups from Wei Yongjun and
Rafael J Wysocki.

- Cleanups and improvements related to system suspend from
Lan Tianyu, Randy Dunlap and Rafael J Wysocki.

- ACPI battery cleanup from Wei Yongjun.

- cpufreq core fixes from Viresh Kumar.

- Elimination of a deadband effect from the cpufreq ondemand
governor and intel_pstate driver cleanups from Stratos Karafotis.

- 350MHz CPU support for the powernow-k6 cpufreq driver from
Mikulas Patocka.

- Fix for the imx6 cpufreq driver from Anson Huang.

- cpuidle core and governor cleanups from Daniel Lezcano,
Sandeep Tripathy and Mohammad Merajul Islam Molla.

- Build fix for the big_little cpuidle driver from Sachin Kamat.

- Configuration fix for the Operation Performance Points (OPP)
framework from Mark Brown.

- APM cleanup from Jean Delvare.

- cpupower utility fixes and cleanups from Peter Senna Tschudin,
Andrey Utkin, Himangi Saraogi, Rickard Strandqvist, Thomas Renninger.

Thanks!
