rcutorture: Add a stall_only module parameter

Browse source

This commit adds a stall_only module parameter that shuts off all
rcutorture kthreads other than the RCU CPU stall-warning test kthreads.
The purpose of this is to test production applictions' reactions to
CPU stalls, and with minimal additional overhead.  Or you can omit the
stall-warning tests as well and get a heavy no-op, your choice!
