What about writing
	if(CHECK_IRQ_PER_CPU(desc->status)) {
		...
	}
in __do_IRQ(),
and
	#if defined(ARCH_HAS_IRQ_PER_CPU)
		#define IRQ_PER_CPU	256	/* IRQ is per CPU */
		#define CHECK_IRQ_PER_CPU(var) ((var) & IRQ_PER_CPU)
	#else
		#define CHECK_IRQ_PER_CPU(var) 0
	#endif
in "include/linux/irq.h" then?

   Gruesse,
   Karsten
