APCs are multiplexed on a single virq.
Yep, I know. Don't know why but I thought that printk_flush is multiplexed on the same virq, OTOH it's an APC too. Well, the easiest argument against that could have been that the APC interface is implemented in the hal but printk_virq is registered in the ipipe, i.e. when there is no APC interface yet, mea culpa.
