Hi all,

Here's an updated dyn-tick patch. Some minor fixes:

- Moved updating of time happen before other interrupts are
  called as noted by Russell King.

- Moved call to next_timer_interrupt to generic code from
  a custom idle module to allow using other idle modules,
  such as amd76x_pm.

- Added some experimental control options under
  /sys/devices/system/timer/timer0.

I've also put together a minimal website for dyn-tick:

The sysfs debug options are following:

Check the state of dyn tick:
cat /sys/devices/system/timer/timer0/dyn_tick_state

Stop dyn-tick, and use normal HZ:
echo 0 > /sys/devices/system/timer/timer0/dyn_tick_state

Re-enabled dyn-tick:
echo 1 > /sys/devices/system/timer/timer0/dyn_tick_state

Lots of debug output to console, don't use this
from main console...

echo 1 > /sys/devices/system/timer/timer0/dyn_tick_dbg

Kill timer interrupt, and update time only from other
interrupts. Only use this for PM experiments. Time
will not stay correct as timers overflow.

echo 1 > /sys/devices/system/timer/timer0/dyn_tick_int
