Geert Uytterhoeven c81407fe57 cpufreq: cpufreq-dt: Restore default cpumask_setall(policy->cpus) ... Commit 34e5a5273d ("cpufreq: cpufreq-dt: extend with platform_data") changed cpufreq_init() to only call cpumask_setall(policy->cpus) if the platform data indicates that all CPUs share the same clock. Before, cpufreq_generic_init() did this unconditionally. This causes a crash on r8a7791/koelsch when resuming from s2ram: Enabling non-boot CPUs ...
