10 Clock scaling allows you to change the clock speed of CPUs on the
11 fly. This is a nice method to save battery power on notebooks,
12 because the lower the clock speed, the less power the CPU consumes.

26 Many CPUFreq drivers use these helpers, so only say N here if
27 the CPUFreq driver of your choice doesn't need these helpers.
