Subject: [PATCH 17/38] platform/x86: Replace deprecated CPU-hotplug functions.
Date: Tue,  3 Aug 2021 16:16:00 +0200	[thread overview]
Message-ID: <20210803141621.780504-18-bigeasy@linutronix.de> (raw)
In-Reply-To: <20210803141621.780504-1-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.
