Merge branches 'acpica', 'acpi-processor' and 'acpi-scan' 

* acpica:
  ACPICA: ACPI 5.1: Add support for runtime validation of _DSD package.

* acpi-processor:
  ACPI / cpuidle: fix deadlock between cpuidle_lock and cpu_hotplug.lock

* acpi-scan:
  ACPI / scan: not cache _SUN value in struct acpi_device_pnp
