This option causes RCU to attempt to accelerate grace periods
- in order to allow the final CPU to enter dynticks-idle state
- more quickly. On the other hand, this option increases the
- overhead of the dynticks-idle checking, particularly on systems
- with large numbers of CPUs.

Say Y if energy efficiency is critically important, particularly
if you have relatively few CPUs.
