Subject: [PATCH 2/3] arm: kexec: fix the primary cpu passed to smp_shutdown_nonboot_cpus()
Date: Fri, 7 Jan 2022 10:05:07 +0800 [thread overview]
Message-ID: <20220107020508.9778-2-kernelfans@gmail.com> (raw)
In-Reply-To: <20220107020508.9778-1-kernelfans@gmail.com>
kernel_kexec()->migrate_to_reboot_cpu() has already pinned the
reboot thread on either reboot_cpu or the first online cpu.
So machine_shutdown() should pass smp_processor_id() as the primary cpu
to smp_shutdown_nonboot_cpus().
