I don't think "irq_break_affinities" is anywhere near a good name - it's
not about always breaking affinities (moving an IRQ off one CPU onto
another within the current affinity setting does not break the affinity.)

irq_migrate_all()

irq_migrate_all_off_this_cpu()

irq_this_cpu_hotunplug()

irq_cpu_hotunplug()
