Merge updates related to system sleep for 5.16-rc1:
- Clean up hib_wait_io() (Falla Coulibaly).
- Fix sparse warnings in hibernation-related code (Anders Roxell).
- Use vzalloc() and kzalloc() instead of their open-coded
equivalents in hibernation-related code (Cai Huoqing).
- Prevent user space from crashing the kernel by attempting to
restore the system state from a swap partition in use (Ye Bin).
- Do not let "syscore" devices runtime-suspend during system PM
transitions (Rafael Wysocki).
- Do not pause cpuidle in the suspend-to-idle path (Rafael Wysocki).
- Pause cpuidle later and resume it earlier during system PM
transitions (Rafael Wysocki).
- Make system suspend code use valid_state() consistently (Rafael
Wysocki).
- Add support for enabling wakeup IRQs after invoking the
->runtime_suspend() callback and make two drivers use it (Chunfeng
Yun).
