[PATCH 03/70] cpufreq: interactive: apply intermediate load to max speed not current

From: BÃlint Czobor
Date: Tue Oct 27 2015 - 13:31:43 EST


From: Todd Poynor <toddpoynor@xxxxxxxxxx>

Evaluate spikes in load (below go_hispeed_load) against the maximum
speed supported by the device, not the current speed (which tends to
make it too difficult to raise speed to intermediate levels until
very busy).
