 Revision 1.1.1.1  2005/09/26 17:23:56  reddawg
 no message

 Revision 1.6  2004/09/11 13:01:05  apwillia
 Make spinlock lock function sched_yield.  Add spinlockLock_scheduler for use in smp-scheduler (avoids recursive call to sched).

 Revision 1.5  2004/07/20 20:25:57  reddawg
 Works perfectly here

 Revision 1.4  2004/07/20 20:20:19  reddawg
 spinlock: made them non inline functions I think this actually fixed the problem

 Revision 1.3  2004/05/21 12:42:32  reddawg
 Cleaned Up
