Subject: [PATCH 09/17] cpufreq/pasemi: Adjust system_state check
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.11/older/patches-4.11.9-rt7.tar.xz
|
|
|
|
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.
