Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm+acpi-4.3-rc4
to receive power management and ACPI material for v4.3-rc4 with top-most commit eb6d1c287ae1f7221248d5be26a5b1560073c09e
Merge branches 'pm-cpuidle', 'pm-opp' and 'pm-tools'
on top of commit 9ffecb10283508260936b96022d4ee43a7798b4c
Linux 4.3-rc3
These are fixes mostly, for a few changes made in this cycle (the intel_idle driver, the OPP library, the ACPI EC driver, turbostat) and for some issues that have just been discovered (ACPI PCI IRQ management, PCI power management documentation, turbostat), with a couple of cleanups on top of them.
Specifics:
- intel_idle driver fixup for the recently added Skylake chips support (Len Brown).
- Operating Performance Points (OPP) library fix related to the recently added support for new DT bindings and a fix for a typo in a comment (Viresh Kumar, Stephen Boyd).
- ACPI EC driver fix for a recently introduced memory leak in an error code path (Lv Zheng).
- ACPI PCI IRQ management fix for the issue where an ISA IRQ is shared with a PCI device which requires it to be configured in a different way and may cause an interrupt storm to happen as a result with an extra ACPI SCI IRQ handling simplification on top of it (Jiang Liu).
- Update of the PCI power management documentation that became outdated and started to actively confuse the readers to make it actually reflect the code (Rafael J Wysocki).
- turbostat fixes including an IVB Xeon regression fix (related to the --debug command line option), Skylake adjustment for the TSC running at a frequency that doesn't match the base one exactly, and a Knights Landing quirk to account for the fact that it only updates APERF and MPERF every 1024 clock cycles plus bumping up the turbostat version number (Len Brown, Hubert Chrzaniuk).
Thanks!
