ouch!

There's a much more shrewd method to achieve the same, via 2 lines total 
patch:

Change the name of CONFIG_CLASSIC_RCU to something else such as 
CONFIG_FLAT_RCU. That does all the magic and more: all configs will 
default to tree-rcu - not just defconfigs! Agreed?

[ I think the gene of laziness is probably more developed in my genome
  than in yours. It is a very useful trait ;-) ]
