rcu: enable CPU_STALL_VERBOSE by default
The CPU_STALL_VERBOSE kernel configuration parameter was added to 2.6.34 to identify any preempted/blocked tasks that were preventing the current grace period from completing when running preemptible RCU. As is conventional for new configurations parameters, this defaulted disabled. It is now time to enable it by default. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
