| Subject: [PATCH 04/17] x86/smp: 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 announce_cpu() to handle the extra states. |
