Help
====

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.
