Description of problem:
The linux-2.4.17-selected-ac-bits.patch breaks real-time scheduling.
A process trying to get real-time priority (sched_setscheduler())
will never really get the requested priority (although sched_getparam())
reports the correct rt_priority).
'ps l' should report a negative PRI for real-time processes but a process
calling sched_setscheduler(0,SCHED_FIFO,&params) will always
show a PRI >= 0.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Let a program call sched_setscheduler(0,SCHED_OTHER,&appropriate_param)
2. run as root
3. test behavior. Run 'ps l'. The process will not be RT scheduled
	

Actual Results:  Process didn't effectively get RT priority

Additional info:

Programs relying on real-time scheduling (e.g. CD burner) may lose data.

Proposed Fix: see patch available at
