Fix CPU hotplug issues with such kthreads. - A fix to not push away tasks on CPUs coming online. - Have workqueue CPU hotplug code use cpu_possible_mask when breaking affinity on CPU offlining so that pending workers can finish on newly arrived onlined CPUs too. - Dump tasks which haven't vacated a CPU which is currently being unplugged. - Register a special scale invariance callback which gets called on resume from RAM to read out APERF/MPERF after resume and thus make the schedutil scaling governor more precise. ---------------------------------------------------------------- Lai Jiangshan (1): workqueue: Use cpu_possible_mask instead of cpu_active_mask to break affinity Peter Zijlstra (7): sched: Don't run cpu-online with balance_push() enabled kthread: Extract KTHREAD_IS_PER_CPU workqueue: Tag bound workers with KTHREAD_IS_PER_CPU workqueue: Restrict affinity change to rescuer sched: Prepare to use balance_push in ttwu() sched: Fix CPU hotplug / tighten is_per_cpu_kthread() sched: Relax the set_cpus_allowed_ptr() semantics Rafael J.
