Merge tag 'pm+acpi-3.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management and ACPI fixes from Rafael Wysocki:

 - Additional CPU ID for the intel_pstate driver from Dirk Brandewie.

 - More cpufreq fixes related to ARM big.LITTLE support and locking from
   Viresh Kumar.

 - VIA C7 cpufreq build fix from Rafał Bilski.

 - ACPI power management fix making it possible to use device power
   states regardless of the CONFIG_PM setting from Rafael J Wysocki.

 - New ACPI video blacklist item from Bastian Triller.

* tag 'pm+acpi-3.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  ACPI / video: Add "Asus UL30A" to ACPI video detect blacklist
  cpufreq: arm_big_little_dt: Instantiate as platform_driver
  cpufreq: arm_big_little_dt: Register driver only if DT has valid data
  cpufreq / e_powersaver: Fix linker error when ACPI processor is a module
  cpufreq / intel_pstate: Add additional supported CPU ID
  cpufreq: Drop rwsem lock around CPUFREQ_GOV_POLICY_EXIT
  ACPI / PM: Allow device power states to be used for CONFIG_PM unset
