From: Thomas Gleixner <tglx@linutronix.de>
commit 719b3680d1f789c1e3054e3fcb26bfff07c3c623 upstream.
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.
