Linus Torvalds f2d285669a Power management updates for 4.17-rc1
- Modify the cpuidle poll state implementation to prevent CPUs from
    staying in the loop in there for excessive times (Rafael Wysocki).
 
  - Add Intel Cannon Lake chips support to the RAPL power capping
    driver (Joe Konno).
 
  - Add reference counting to the device links handling code in the
    PM core (Lukas Wunner).
 
  - Avoid reconfiguring GPEs on suspend-to-idle in the ACPI system
    suspend code (Rafael Wysocki).
 
  - Allow devices to be put into deeper low-power states via ACPI
    if both _SxD and _SxW are missing (Daniel Drake).
 
  - Reorganize the core ACPI suspend-to-idle wakeup code to avoid a
    keyboard wakeup issue on Asus UX331UA (Chris Chiu).
 
  - Prevent the PCMCIA library code from aborting suspend-to-idle due
    to noirq suspend failures resulting from incorrect assumptions
    (Rafael Wysocki).
 
  - Add coupled cpuidle supprt to the Exynos3250 platform (Marek
    Szyprowski).
 
  - Add new sysfs file to make it easier to specify the image storage
    location during hibernation (Mario Limonciello).
 
  - Add sysfs files for collecting suspend-to-idle usage and time
    statistics for CPU idle states (Rafael Wysocki).
 
  - Update the pm-graph utilities (Todd Brandt).
 
  - Reduce the kernel log noise related to reporting Low-power Idle
    constraings by the ACPI system suspend code (Rafael Wysocki).
 
  - Make it easier to distinguish dedicated wakeup IRQs in the
    /proc/interrupts output (Tony Lindgren).
 
  - Add the frequency table validation in cpufreq to the core and
    drop it from a number of cpufreq drivers (Viresh Kumar).
 
  - Drop "cooling-{min|max}-level" for CPU nodes from a couple of
    DT bindings (Viresh Kumar).
 
  - Clean up the CPU online error code path in the cpufreq core
    (Viresh Kumar).
 
  - Fix assorted issues in the SCPI, CPPC, mediatek and tegra186
    cpufreq drivers (Arnd Bergmann, Chunyu Hu, George Cherian,
    Viresh Kumar).

Pull power management updates from Rafael Wysocki:
 "These update the cpuidle poll state definition to reduce excessive
  energy usage related to it, add new CPU ID to the RAPL power capping
  driver, update the ACPI system suspend code to handle some special
  cases better, extend the PM core's device links code slightly, add new
  sysfs attribute for better suspend-to-idle diagnostics and easier
  hibernation handling, update power management tools and clean up
  cpufreq quite a bit.
