ACPI: Separate invocations of _GTS and _BFS from _PTS and _WAK
The execution of ACPI global control methods _GTS and _BFS is currently tied to the preparation to enter a sleep state and to the leaving of the sleep state, respectively. However, these functions are called before disabling the nonboot CPUs and after enabling them, respectively (in fact, on ACPI 1.0x systems the first of them ought to be called before suspending devices), while according to the ACPI specification, _GTS is to be executed right prior to entering the system sleep state and _BFS is to be executed right after the platfor firmware has returned control to the OS on wake up. Move the execution of _GTS and _BFS to the right places. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Len Brown <len.brown@intel.com>
