Subject: [PATCH 16/38] sgi-xpc: Replace deprecated CPU-hotplug functions.
Date:   Tue,  3 Aug 2021 16:15:59 +0200

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.
