This works because moving aggressively to RCU_SYSIDLE_NOT affects only performance, not correctness, and on small systems, the performance impact should be negligible. That said, this difference does make RCU a bit more complex, and RCU does not seem to be suffering from any lack of complexity. This commit therefore adjusts small-system operation to match that of large systems, so that the state never moves back to RCU_SYSIDLE_NOT from RCU_SYSIDLE_SHORT.
