Even more, should the firmware report an illegal interrupt\nnumber that overlaps with the GIC SGI range, this can result in an\nIPI being unmapped, and subsequent fireworks (as reported by Dann\nFrazier).\n\nRework the driver to have a slightly saner behaviour and actually\ncheck whether the interrupt has been mapped before unmapping things."
