(Frederic Weisbecker) - Improve the interactive/cpu-intense fairness calculation (Josef Bacik) - Improve the PELT code and related cleanups (Peter Zijlstra) - Improve the logic of pick_next_task_fair() (Uladzislau Rezki) - Improve the RT IPI based balancing logic (Steven Rostedt) - Various micro-optimizations: - better !CONFIG_SCHED_DEBUG optimizations (Patrick Bellasi) - better idle loop (Cheng Jian) - ... plus misc fixes, cleanups and updates.
