Rafael Wysocki of Intel sent in the ACPI and power management updates for the Linux 4.1 kernel. As usual, there's a lot of new code part of this big pull request.

There's a ton of power management related changes for the Linux 4.1 kernel as outlined by Wysocki's pull request. The highlights that caught my attention include:

- The intel_idle driver now includes support for the Silvermont core in the Bay Trail SoC. The intel_idle update also adds Airmont support for the forthcoming Intel Cherry Trail and Braswell SoC.

- Generic power management domains support updates with new callbacks to provide for better device initialization.

- There's a new cpufreq driver for the HiSilicon ACPU.

- The intel_pstate scaling driver adds support for Intel's Knights Landing MIC chip.

- The Powercap RAPL driver update adds support for Intel Broadwell Xeon server processors.

- ACPI backlight handling improvements.

- Various new quirks and other code clean-ups / fixes.
