of the old API.

 * The IRQ bitmap provides a global map of bound IRQ vectors for a

 * given platform. Allocation of IRQs are either static through the CPU

 * vector map, or dynamic in the case of board mux vectors or MSI.

 *

 * As this is a central point for all IRQ controllers on the system,

 * each of the available sources are mapped out here. This combined with

 * sparseirq makes it quite trivial to keep the vector map tightly packed

 * when dynamically creating IRQs, as well as tying in to otherwise

 * unused irq_desc positions in the sparse array.
