As such, a valid ID is needed.\n\nIf an MPIDR check fails in acpi_map_gic_cpu_interface() it is possible\nfor the entry in cpu_madt_gicc[cpu] == NULL.  This function would\nthen cause a NULL pointer dereference.   Whilst a path to trigger\nthis has not been established, harden this caller against the\npossibility."
