Hi, All

I got confused with the LinSched main loop...
My understanding is:

	while (not time up) {
		
		get all cpus whose next event is the left most
		
		for those cpus {

			simulate hres clock interrupt		
			
			process_all_softirqs() ?			

			if cpu is idle
				enter idle
			else
				check process running time
		}
	}

Wonder why we need to call process_all_softirqs which will process other
cpu's pending soft irq here?
