Wysocki" , Len Brown , linux-acpi@vger.kernel.org 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. Signed-off-by: Thomas Gleixner Cc: "Rafael J.
