NOTES:
If there are more processors available than configured, the rest will be
ignored. In uniprocessor configuration, this configuration define is
ignored.
This configuration option is only evaluated in SMP configurations (e.g. RTEMS
was built with the ``--enable-smp`` build configuration option). In all
other configurations it has no effect.
