The x86_64 interrupt subsystem is oriented towards vectors, as opposed to a flat irq space as it is in x86-32. This patch adds a simple identity irq->vector mapping so that we can continue to feed irqs into do_IRQ() and get a good result. Ideally x86_32 will unify with the 64-bit code and use vectors too. At that point we can move to mapping event channels to vectors, which will allow us to economise on irqs (so per-cpu event channels can share irqs, rather than having to allocte one per cpu, for example).
