| Subject | [patch 04/18] x86/smp: Adjust system_state check |
| Message-ID | <tH6KB-5j9-7@gated-at.bofh.it> |
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 announce_cpu() to handle the extra states.
