Merge tag 'pm+acpi-4.0-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management and ACPI fixes from Rafael Wysocki:
 "These are stable-candidate fixes of some recently reported issues in
  the cpufreq core, cpuidle core, the ACPI cpuidle driver and the
  hibernate core.

  Specifics:

   - Revert a 3.17 hibernate commit that was supposed to fix an issue
     related to e820 reserved regions, but broke resume from hibernation
     on Lenovo x230 (Rafael J Wysocki).

   - Prevent the ACPI cpuidle driver from overwriting the name and
     description of the C0 state set by the core when the list of
     C-states changes (Thomas Schlichter).

   - Remove the no longer needed state_count field from struct
     cpuidle_device which prevents the list of C-states shown by the
     sysfs interface from becoming incorrect when the current number of
     them is different from the number of C-states on boot (Bartlomiej
     Zolnierkiewicz).

   - The cpufreq core updates the policy object of the only online CPU
     during system resume to make it reflect the current hardware state,
     but it always assumes that CPU to be CPU0 which need not be the
     case, so fix the code to avoid that assumption (Viresh Kumar)"
