[PATCH 68/70] subsystem: CPU FREQUENCY DRIVERS- Set cpu_load calculation on current frequency

From: BÃlint Czobor
Date: Tue Oct 27 2015 - 13:34:14 EST


In timer, cpu_load is calcuated on target_freq.
cpu_load = loadadjfreq / pcpu->target_freq;
But cpu is actually running on current freq i.e. pcpu->policy->cur. So cpu_load
should be calculated on current frequency.
cpu_load = loadadjfreq / pcpu->policy->cur;
