 *
 * @ingroup TestsuitesValidationSmpOnly0
 *
 * @brief Tests SMP-specific thread behaviour.
 *
 * This test case performs the following actions:
 *
 * - Create three worker threads and a mutex.  Use the mutex and the worker to
 *   move to a helping scheduler.
 *
 *   - Pin the runner thread while it executes on a processor owned by a
 *     helping scheduler.
 *
 *   - Pin and unpin the runner thread.  This is a nested operation.
 *
 *   - Preempt the pinned runner thread.  Worker B and C execute at the same
 *     time on processor 0 and 1 respectively for some point in time.  This
 *     shows that the pinning of the runner thread is maintained.
 *
 *   - Unpin the runner thread.  The runner moves back to its home scheduler.
 *
 *   - Release the mutex.
 *
 *   - Pin the runner thread.  Unpin the runner thread while it is suspended.
 *
 *   - Make sure the worker released the mutex.
 *
 *   - Clean up all used resources.
 *
 * - Create three worker threads and a mutex.  Use the mutex and the worker to
 *   check that a suspended thread does not reconsider help requests.
 *
 *   - Let worker B help worker A through the mutex.  Preempt worker A.  Delay
 *     the thread switch to worker A.
 *
 *   - Suspend worker A and let it wait on its thread state lock.  Check that
 *     worker A did not reconsider help requests.
 *
 *   - Resume worker A.  Check that worker A did reconsider help requests after
 *     the thread dispatch.
 *
 *   - Clean up all used resources.
 *
 * - Create four worker threads and three mutexes.  Provoke an explicit thread
 *   priority change while a priority inheritance change is in progress.  The
 *   explicit thread priority change propagates through priority inheritance.
 *
 *   - Create the following dependencies MA -> WA and TC -> MB -> WA.
 *
 *   - Acquire the worker A default thread wait lock.  Start creating the
 *     dependency TB -> MB (we already have MB -> WA).  Make sure it stops
 *     while acquiring the worker A default thread wait lock.  Prepare the
 *     worker A default thread wait lock release.  Raise the worker C priority.
 *     This operation will call the wrapped _Thread_queue_Path_acquire() and
 *     trigger the prepared release of the worker A default thread wait lock.
 *     The worker A default wait lock critical sections will execute now in the
 *     prepared sequence.
 *
 *   - Clean up all used resources.
