parisc: blink all or loadavg LEDs on oops
- depending on machine type, blink all leds or just the loadavg leds twice a second on oops. - cancel_rearming_delayed_workqueue() is obsolete, use cancel_delayed_work_sync() instead Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
