The GIC interface numbering does not necessarily follow the logical CPU numbering, especially for complex topologies such as multi-cluster systems. Fortunately we can easily probe the GIC to create a mapping as the Interrupt Processor Targets Registers for the first 32 interrupts are read-only, and each field returns a value that always corresponds to the processor reading the register. Initially all mappings target all CPUs in case an IPI is required to boot secondary CPUs. It is refined as those CPUs discover what their actual mapping is.
