Author: anevilyak
Date: 2009-12-12 01:01:33 +0100 (Sat, 12 Dec 2009)
New Revision: 34638
Changeset: http://dev.haiku-os.org/changeset/34638/haiku

Modified:
   haiku/trunk/src/system/kernel/Jamfile
   haiku/trunk/src/system/kernel/scheduler/scheduler_affine.cpp
Log:
Small cleanup: As the cpu_ent struct now tracks the running thread directly, 
the affine scheduler can use that instead of keeping track internally.
