APA Scheduler Documentation Missing?

Hi

Looking at the list of schedulers available in confdefs.h based on the
following comment block:

*  - CONFIGURE_SCHEDULER_PRIORITY - Deterministic Priority Scheduler
 *  - CONFIGURE_SCHEDULER_PRIORITY_SMP - Deterministic Priority SMP
Scheduler
 *  - CONFIGURE_SCHEDULER_PRIORITY_AFFINITY_SMP - Deterministic
 *    Priority SMP Affinity Scheduler
 *  - CONFIGURE_SCHEDULER_STRONG_APA - Strong APA Scheduler
 *  - CONFIGURE_SCHEDULER_SIMPLE - Light-weight Priority Scheduler
 *  - CONFIGURE_SCHEDULER_SIMPLE_SMP - Simple SMP Priority Scheduler
 *  - CONFIGURE_SCHEDULER_EDF - EDF Scheduler
 *  - CONFIGURE_SCHEDULER_EDF_SMP - EDF SMP Scheduler
 *  - CONFIGURE_SCHEDULER_CBS - CBS Scheduler
 *  - CONFIGURE_SCHEDULER_USER  - user provided scheduler
 *

I don't think Strong APA is documented in configuring a system or
scheduler concepts. Arbitrary Priority is used as the name.

I suspect most of the information is here but there is some naming
inconsistency and APA as an acronym or the configure_xxx constant
is not documented.
