 * The flat IRQ space is divided into two regions:

 *  1. A one-to-one mapping of real physical IRQs. This space is only used

 *     if we have physical device-access privilege. This region is at the

 *     start of the IRQ space so that existing device drivers do not need

 *     to be modified to translate physical IRQ numbers into our IRQ space.

 *  3. A dynamic mapping of inter-domain and Xen-sourced virtual IRQs. These

 *     are bound using the provided bind/unbind functions.
