     [NET]: rfkill: add support for input key to control wireless radio

added this 64-bit bug:

        ....
	unsigned int flags;

 	spin_lock_irqsave(&task->lock, flags);
        ....

irq 'flags' must be unsigned long, not unsigned int. The -rt tree has
strict checks about this on 64-bit so this triggered a build failure.
