rcu: print boot-time console messages if RCU configs out of ordinary
Print boot-time messages if tracing is enabled, if fanout is set to non-default values, if exact fanout is specified, if accelerated dyntick-idle grace periods have been enabled, if RCU-lockdep is enabled, if rcutorture has been boot-time enabled, if the CPU stall detector has been disabled, or if four-level hierarchy has been enabled. This is all for TREE_RCU and TREE_PREEMPT_RCU. TINY_RCU will be handled separately, if at all. Suggested-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
