But normally do_timer() is called just once, isn't it? These loops
are just for lost ticks, which would be rarely happened. So I think
tunning for usual case is better.
If you switch of the hz timer in idle you'll get lots of lost ticks.
And if you are
running a virtualized system you can loose you cpu for some ticks as well.
Pass the number of ticks to do_timer.
