| Message-ID | <tHPRo-M2-29@gated-at.bofh.it> |
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. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Cc: "Rafael J.
