Description (last modified by Sebastian Huber)
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 processors 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.
