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

From: Todd Poynor <toddpoynor@...gle.com>

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).
