Paul E. McKenney cdc694b235 rcu: Add kernel parameter to dump trace after RCU CPU stall warning 
This commit adds a rcu_cpu_stall_ftrace_dump kernel boot parameter, that,
when set, causes the trace buffer to be dumped after an RCU CPU stall
warning is printed.  This kernel boot parameter is disabled by default,
maintaining compatibility with previous behavior.
