Benjamin Segall ce76392523 kvm: exit halt polling on need_resched() as well ... commit 262de4102c upstream. single_task_running() is usually more general than need_resched() but CFS_BANDWIDTH throttling will use resched_task() when there is just one task to get the task to block. This was causing long-need_resched warnings and was likely allowing VMs to overrun their quota when halt polling.
