 /proc/irq/IRQ#/smp_affinity specifies which target CPUs are permitted
 for a given IRQ source. It's a bitmask of allowed CPUs. It's not allowed
 to turn off all CPUs, and if an IRQ controller does not support IRQ
 affinity then the value will not change from the default 0xffffffff.
 
-/proc/irq/default_smp_affinity specifies default affinity mask that applies
-to all non-active IRQs. Once IRQ is allocated/activated its affinity bitmask
-will be set to the default mask. It can then be changed as described above.
-Default mask is 0xffffffff.

 Here is an example of restricting IRQ44 (eth1) to CPU0-3 then restricting
