Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm+acpi-4.6-rc7
to receive power management and ACPI fixes for v4.6-rc7 with top-most commit 5f2f88e330e7ee2d2d7c5e0984b86108b00ac800
Merge branches 'pm-opp-fixes', 'pm-cpufreq-fixes' and 'pm-cpuidle-fixes'
on top of commit 04974df8049fc4240d22759a91e035082ccd18b4
Linux 4.6-rc6
Fixes for problems introduced or discovered recently (intel_pstate, sti-cpufreq, ARM64 cpuidle, Operating Performance Points framework, generic device properties framework) and one fix for a hotplug-related deadlock in ACPICA that's been there forever, but is nasty enough.
Specifics:
- Fix for a recent regression in the intel_pstate driver causing it to fail to restore the HWP (HW-managed P-states) configuration of the boot CPU after suspend-to-RAM (Rafael Wysocki).
- Fix for two recent regressions in the intel_pstate driver, one that can trigger a divide by zero if the driver is accessed via sysfs before it manages to take the first sample and one causing it to fail to update a structure field used in a trace point, so the information coming from it is less useful (Rafael Wysocki).
- Fix for a problem in the sti-cpufreq driver introduced during the 4.5 cycle that causes it to break CPU PM in multi-platform kernels by registering cpufreq-dt (which subsequently doesn't work) unconditionally and preventing the driver that would actually work from registering (Sudeep Holla).
- Stable-candidate fix for an ARM64 cpuidle issue causing idle state usage counters to be incorrectly updated for idle states that were not entered due to errors (James Morse).
- Fix for a recently introduced issue in the OPP (Operating Performance Points) framework causing it to print bogus error messages for missing optional regulators (Viresh Kumar).
- Fix for a recently introduced issue in the generic device properties framework that may cause it to attempt to dereferece and invalid pointer in some cases (Heikki Krogerus).
- Fix for a deadlock in the ACPICA core that may be triggered by device (eg. Thunderbolt) hotplug (Prarit Bhargava).
Thanks!
