I hacked some things to run the tests with the new scheduler. I added also the
support for the preempt mode (this makes no sense on SMP). The following tests
sp02 - This is a bug in the test. I will send a fix.
sp66 - I think there is a bug in the test.
spfatal03 - Fails due to RTEMS_SMP is defined.
tm20 - Didn't look at it since this test tinkers with internal variables.
tm27 - Ditto.
The test sp66 checks the priority ceiling protocol. The problem is that the
driver task has preemption disabled:
puts( "Calling semaphore release" );
status = rtems_semaphore_release( Mutex_id );
directive_failed( status, "rtems_semaphore_release" );
To make sure the priority ceiling works, we have to check that Task_1 actually
runs which is impossible since Init has preempt disabled.
puts( "*** END OF TEST 65 ***" );
