Subject: [PATCH v2 02/14] ia64: Replace cpu_down with smp_shutdown_nonboot_cpus()
Date: Mon, 25 Nov 2019 11:27:42 +0000 [thread overview]
Message-ID: <20191125112754.25223-3-qais.yousef@arm.com> (raw)
In-Reply-To: <20191125112754.25223-1-qais.yousef@arm.com>
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.
