Subject: [patch 03/18] arm64: Adjust system_state check
Date: Sun, 14 May 2017 20:27:19 +0200 [thread overview]
Message-ID: <20170514183612.687619555@linutronix.de> (raw)
In-Reply-To: 20170514182716.347236777@linutronix.de
[-- Attachment #1: arm64--Adjust-system_state-check.patch --]
[-- Type: text/plain, Size: 939 bytes --]
To enable smp_processor_id() and might_sleep() debug checks earlier, it's
required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING.
Adjust the system_state check in smp_send_stop() to handle the extra states.
