Subject: [PATCH v5 2/2] cpuhp: Set cpuhp target for boot cpu
Date: Thu, 17 Nov 2022 11:23:29 -0500 [thread overview]
Message-ID: <20221117162329.3164999-3-pauld@redhat.com> (raw)
In-Reply-To: <20221117162329.3164999-1-pauld@redhat.com>
Since the boot cpu does not go through the hotplug process it ends
up with state == CPUHP_ONLINE but target == CPUHP_OFFLINE.
So set the target to match in boot_cpu_hotplug_init().
