Linus Torvalds 872912352c ACPI and power management updates for v3.20-rc1
- Rework of the core ACPI resources parsing code to fix issues
    in it and make using resource offsets more convenient and
    consolidation of some resource-handing code in a couple of places
    that have grown analagous data structures and code to cover the
    the same gap in the core (Jiang Liu, Thomas Gleixner, Lv Zheng).
 
  - ACPI-based IOAPIC hotplug support on top of the resources handling
    rework (Jiang Liu, Yinghai Lu).
 
  - ACPICA update to upstream release 20150204 including an interrupt
    handling rework that allows drivers to install raw handlers for
    ACPI GPEs which then become entirely responsible for the given GPE
    and the ACPICA core code won't touch it (Lv Zheng, David E Box,
    Octavian Purdila).
 
  - ACPI EC driver rework to fix several concurrency issues and other
    problems related to events handling on top of the ACPICA's new
    support for raw GPE handlers (Lv Zheng).
 
  - New ACPI driver for AMD SoCs analogous to the LPSS (Low-Power
    Subsystem) driver for Intel chips (Ken Xue).
 
  - Two minor fixes of the ACPI LPSS driver (Heikki Krogerus,
    Jarkko Nikula).
 
  - Two new blacklist entries for machines (Samsung 730U3E/740U3E and
    510R) where the native backlight interface doesn't work correctly
    while the ACPI one does (Hans de Goede).
 
  - Rework of the ACPI processor driver's handling of idle states
    to make the code more straightforward and less bloated overall
    (Rafael J Wysocki).
 
  - Assorted minor fixes related to ACPI and SFI (Andreas Ruprecht,
    Andy Shevchenko, Hanjun Guo, Jan Beulich, Rafael J Wysocki,
    Yaowei Bai).
 
  - PCI core power management modification to avoid resuming (some)
    runtime-suspended devices during system suspend if they are in
    the right states already (Rafael J Wysocki).
 
  - New SFI-based cpufreq driver for Intel platforms using SFI
    (Srinidhi Kasagar).
 
  - cpufreq core fixes, cleanups and simplifications (Viresh Kumar,
    Doug Anderson, Wolfram Sang).
 
  - SkyLake CPU support and other updates for the intel_pstate driver
    (Kristen Carlson Accardi, Srinivas Pandruvada).
 
  - cpufreq-dt driver cleanup (Markus Elfring).
 
  - Init fix for the ARM big.LITTLE cpuidle driver (Sudeep Holla).

Pull ACPI and power management updates from Rafael Wysocki:
 "We have a few new features this time, including a new SFI-based
  cpufreq driver, a new devfreq driver for Tegra Activity Monitor, a new
  devfreq class for providing its governors with raw utilization data
  and a new ACPI driver for AMD SoCs.

  Still, the majority of changes here are reworks of existing code to
  make it more straightforward or to prepare it for implementing new
  features on top of it.  The primary example is the rework of ACPI
  resources handling from Jiang Liu, Thomas Gleixner and Lv Zheng with
  support for IOAPIC hotplug implemented on top of it, but there is
  quite a number of changes of this kind in the cpufreq core, ACPICA,
  ACPI EC driver, ACPI processor driver and the generic power domains
  core code too.

  The most active developer is Viresh Kumar with his cpufreq changes.

  Specifics:
