Notes:
[2012/5/1 pfefferz] File notes here
[2012/5/9 vishalbhoj] Interactive governor is now functional with the arm-bl-cpufreq driver. The proposal for the demo is to install a cpu load monitor which indicates the load in the notification bar and then run a benchmark application which will load the cpu to 100 % and the execution switches to big core and when we stop the benchmark application then switches back to the little core. The documentation is being done at https://wiki.linaro.org/Internal/Projects/Big.Little.Switcher/AndroidDemo
