Subject: [PATCH 21/70] cpufreq: interactive: always limit initial speed bump to hispeed

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

First bump speed up to hispeed_freq whenever the current speed is below
hispeed_freq, instead of only when the current speed is the minimum speed.
The previous code made it too difficult to use hispeed_freq as a common
intermediate speed on systems that frequently run at speeds between
minimum and hispeed_freq.
