2.6.21.4-rt12 boots on 4-CPU Opteron and passes several hours of 
rcutorture.  However, if I simply do "modprobe rcutorture", the kernel 
threads do not spread across the CPUs as I would expect them to, even 
given CFS.  Instead, the readers all stack up on a single CPU, and I 
have to use the "taskset" command to spread them out manually.  Is 
there some config parameter I am missing out on?

hm, what affinity do they start out with? Could they all be pinned to 
CPU#0 by default?
