Power management and ACPI fixes for v4.2-rc5 - Fix a recently introduced issue in the cpufreq core causing it to attempt to create duplicate symbolic links to the policy directory in sysfs for CPUs that are offline when the cpufreq driver is being registered (Rafael J Wysocki). - Fix a recently introduced problem in the ACPI device power management core code causing it to store an incorrect value in the device object's power.state field in some cases which in turn leads to attempts to turn power resources off while they should still be on going forward (Mika Westerberg). - Fix an intel_pstate driver issue introduced during the 4.1 cycle which leads to kernel panics on boot on Knights Landing chips due to incomplete support for them in that driver (Lukasz Anaczkowski). /
