Not directly related, but that reminds me that I noticed the
other day that we have VGIC_MAX_IRQS = 1024 (and use that as a
guard on how many irqs we let userspace configure and ask us
to deliver), but that doesn't account for the couple of magic
numbers at the top of the range. I think that lets userspace
cause us to do UNPREDICTABLE things to the GIC...
