So gcc-4.3 complains that "array subscript is above array bounds", even though this function is never called on those systems. This adds a check for NR_IRQS <= 16, which effectively optimizes init_srm_irq() code away on problematic platforms. Thanks to Daniel Drake <dsd@xxxxxxxxxx> for detailed analysis of the problem.
