IRQs which have not yet been allocated/activated, and hence which lack a
/proc/irq/[0-9]* directory.
+The node file on an SMP system shows the node to which the device using the IRQ

prof_cpu_mask specifies which CPUs are to be profiled by the system wide
profiler. Default value is ffffffff (all cpus).
