Tricky part is the name of this routine: add_additional_sysfs_entries().
I am not proposing additional set of directories inside cpu/cpu*/cpufreq/
but either of cpu/cpufreq/ or cpu/cpu*/cpufreq/ for governor.
And so, keeping that additional variable looks a better solution. Let me
get a patch with this change only and see how it looks.
