Frederic Weisbecker f268c3737e tick/nohz: Only check for RCU deferred wakeup on user/guest entry when needed ... Checking for and processing RCU-nocb deferred wakeup upon user/guest entry is only relevant when nohz_full runs on the local CPU, otherwise the periodic tick should take care of it. Make sure we don't needlessly pollute these fast-paths as a -3% performance regression on a will-it-scale.per_process_ops has been reported so far.
