| Subject: [PATCH 13/17] extable: Adjust system_state checks |
| |
| 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 core_kernel_text() to handle the extra |
| states, i.e. to cover init text up to the point where the system switches |
| to state RUNNING. |
