+Fix for a bug in led-triggers.c plus an update to the
+timer trigger code to allow for fractional frequency

 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.
+set the LED with the trigger to different states (on,
+flashing or off) according to whether or not all CPUs
+are idle.
