rcu: Kconfig help needs to say that TREE_PREEMPT_RCU scales down
To quote Valdis:
This leaves somebody who has a laptop wondering which
choice is best for a system with only one or two cores that
has CONFIG_PREEMPT defined. One choice says it scales down
nicely, the other explicitly has a 'depends on PREEMPT'
attached to it...
So add "scales down nicely" to TREE_PREEMPT_RCU to match that of
TREE_RCU.
