[PATCH] Make dyntick work again

Hi all,

Here's a quick patch to make dyntick work on omap again
after the clocksource changes. It now uses the Linux 
common implementation instead of the ARM specific one.

I haven't tested this patch much yet, except:

# grep time /proc/interrupts; sleep 10; grep time /proc/interrupts

Drops the ticks to below 10.

Regards,

Tony
