From: Thomas Gleixner <tglx@xxxxxxxxxxxxx> commit d04e31a23c3c828456cb5613f391ce4ac4e5765f 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 pas_cpufreq_cpu_exit() to handle the extra states.
