[PATCH] clockevents: i386 drivers
Add clockevent drivers for i386: lapic (local) and PIT/HPET (global). Update
the timer IRQ to call into the PIT/HPET driver's event handler and the
lapic-timer IRQ to call into the lapic clockevent driver. The assignement of
timer functionality is delegated to the core framework code and replaces the
compile and runtime evalution in do_timer_interrupt_hook()
Use the clockevents broadcast support and implement the lapic_broadcast
function for ACPI.
No changes to existing functionality.
