5.10-stable review patch. If anyone has any objections, please let me know.

From: Sebastian Andrzej Siewior bigeasy@linutronix.de
[ Upstream commit 698429f9d0e54ce3964151adff886ee5fc59714b ]
The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock().
Replace deprecated CPU-hotplug functions with the official version. The behavior remains unchanged.
