From ef284f5ca5f102bf855e599305c0c16d6e844635 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 16 May 2017 20:42:34 +0200 Subject: [PATCH] arm64: Adjust system_state check 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.
