# HEAD: 25de110d148666752dc0e0da7a0b69de31cd7098 irq_work: Define
irq_work_single() on !CONFIG_IRQ_WORK too
The changes in this cycle are:
- Optimize the task wakeup CPU selection logic, to improve scalability and
reduce wakeup latency spikes
- PELT enhancements
- CFS bandwidth handling fixes
- Optimize the wakeup path by remove rq->wake_list and replacing it with
->ttwu_pending
- Optimize IPI cross-calls by making flush_smp_call_function_queue()
process sync callbacks first.
- Misc fixes and enhancements.
