[patch V2 07/17] ACPI: Adjust system_state check

From: Thomas Gleixner
Date: Tue May 16 2017 - 14:53:15 EST


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.
