Again how did you just narrow down to the list above ? Is that just a
random pick ? As I suggested with corresponding cpuidle changes, please
look into the details in side the for_each_possible_cpu() loop and then
decide if it applies or not.

For me, it applied to the below files as well at the least.

drivers/cpufreq/mvebu-cpufreq.c
drivers/cpufreq/qcom-cpufreq-hw.c
drivers/cpufreq/scmi-cpufreq.c
drivers/cpufreq/scpi-cpufreq.c
drivers/cpufreq/virtual-cpufreq.c

Please check everything thoroughly as I just looked at these briefly.
