Merge branch 'acpi-pm'
* acpi-pm:
ACPI / PM: Rework and clean up acpi_dev_pm_get_state()
ACPI / PM: Replace ACPI_STATE_D3 with ACPI_STATE_D3_COLD in device_pm.c
ACPI / PM: Rename function acpi_device_power_state() and make it static
ACPI / PM: acpi_processor_suspend() can be static
xen / ACPI / sleep: Register an acpi_suspend_lowlevel callback.
x86 / ACPI / sleep: Provide registration for acpi_suspend_lowlevel.
