From 1daf08a066cfe500587affd3fa3be8c13b8ff007 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Tue, 3 Aug 2021 16:16:09 +0200 Subject: livepatch: Replace deprecated CPU-hotplug functions. 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.
