Subject: [PATCH 27/38] padata: Replace deprecated CPU-hotplug functions.
Date:   Tue,  3 Aug 2021 16:16:10 +0200
Message-Id: <20210803141621.780504-28-bigeasy@linutronix.de>

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.
