Subject: [PATCH 3/3] cpu/hotplug: Rename enable_nonboot_cpus()
Date:   Thu,  9 Apr 2020 12:27:42 +0100
Message-Id: <20200409112742.3581-3-qais.yousef@arm.com>
In-Reply-To: <20200409112742.3581-1-qais.yousef@arm.com>
References: <20200409112742.3581-1-qais.yousef@arm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Now that disable_nonboot_cpus was removed in favour of
freeze_secondary_cpus(), rename enable_nonboot_cpus() to
thaw_secondary_cpus() to preserve the naming symmetry.

Done automatically via:

	git grep -l enable_nonboot_cpus | xargs sed -i 's/enable_nonboot_cpus/thaw_secondary_cpus/g'
