[-- Attachment #1: x86-smp--Adjust-system_state-check.patch --]
[-- Type: text/plain, Size: 726 bytes --]

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.
