+This patches the new LEDs code to add cpu activity and
+inactivity triggers to the timer triggers. The new triggers
+flash an LED at a given rate when the CPU is active and
+set it to on (cpu-idle) or off (cpu-activity trigger) when
+the CPU is idle.
+
+The patch also adds a duty_cycle attribute to the LED
+timer class, this allows control of the mark/space ratio
+in the flash. Using duty cycles of about 50% far higher
+flash rates become possible.
