Subject: [PATCH v2 02/14] ia64: Replace cpu_down with smp_shutdown_nonboot_cpus()
Date:   Mon, 25 Nov 2019 11:27:42 +0000
Message-Id: <20191125112754.25223-3-qais.yousef@arm.com>
In-Reply-To: <20191125112754.25223-1-qais.yousef@arm.com>
References: <20191125112754.25223-1-qais.yousef@arm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use the new smp_shutdown_nonboot_cpus() instead of open coding using
cpu_down() directly.

This also prepares to make cpu_up/down a private interface for anything
but the cpu subsystem.
