------------------------------+--------------------------------
 The SMP EDF scheduler supports a one-to-one and one-to-all thread to
 processor affinity. Currently it accepts affinity sets which are a proper
 subset of the online processor containing at least two processors owned by
 the scheduler. In this case it sets a one-to-one thread to processor
 affinity. This leads to undefined behaviour if a processor is removed
 since the higher level check in rtems_scheduler_remove_processor() does
 not account for this implementation detail.
