(and frankly, and this may not be very popular on this list, CPUFREQ is pretty much beyond fixing. The locking rules are completely hosed, but more, the assumption that you can or should detangle policy from the hardware is fundamentally flawed. The policy IS hardware specific. Because it's tuned for specific hardware behavior, if you actually optimize it) -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
