| Subject: [PATCH 07/17] ACPI: 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. |
| |
| Make the decision whether a pci root is hotplugged depend on SYSTEM_RUNNING |
| instead of !SYSTEM_BOOTING. It makes no sense to cover states greater than |
| SYSTEM_RUNNING as there are not hotplug events on reboot and poweroff. |
