-	  Select this option if you want to disable continuous timer ticks
-	  and have them programmed to occur as required. This option saves
-	  power as the system can remain in idle state for longer.
-
-	  By default dynamic tick is disabled during the boot, and can be
-	  manually enabled with:
-
-	    echo 1 > /sys/devices/system/timer/timer0/dyn_tick
-
-	  Alternatively, if you want dynamic tick automatically enabled
-	  during boot, pass "dyntick=enable" via the kernel command string.
-
-	  Please note that dynamic tick may affect the accuracy of
-	  timekeeping on some platforms depending on the implementation.
-	  Currently at least OMAP, PXA2xx and SA11x0 platforms are known
-	  to have accurate timekeeping with dynamic tick.
