Description

Cloned from #4358:

The priority queues in clustered scheduling configurations use a per scheduler priority queue rotation to ensure FIFO fairness across schedulers. This mechanism is implemented in the thread queue surrender operation. Unfortunately some semaphore and message queue directives use wrongly the thread queue extract operation.

Please use RTEMS 6 for SMP. Please reopen if this is to be fixed on the RTEMS 5 branch.
