Pull power management and ACPI fixes from Rafael Wysocki:
 "These fix three regressions, two recent ones (cpufreq core and ACPI
  device power management) and one introduced during the 4.1 cycle
  (intel_pstate).

  Specifics:

   - 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)"

* tag 'pm+acpi-4.2-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  cpufreq: Avoid attempts to create duplicate symbolic links
  ACPI / PM: Use target_state to set the device power state
  intel_pstate: Add get_scaling cpu_defaults param to Knights Landing
