Subject[PATCH 04/70] cpufreq: interactive: set at least hispeed when above hispeed load
Date
From: Todd Poynor <toddpoynor@google.com>

If load is above go_hispeed_load, always go to at least hispeed_freq,
even when reducing speed from a higher speed, not just when jumping
up from minimum speed. Avoids running at a lower than intended
speed after a burst of even higher load.
