    On some architectures, part of the vector table may be reserved for
    system exceptions and is declared separately from the tables
    created by gen_isr_tables.py. When creating these tables, this value
    will be subtracted from CONFIG_NUM_IRQS to properly size them.
    This is a hidden option which needs to be set per architecture and
    left alone.
