[PATCH] enhanced reimplemention of the kfifo API
This is a complete reimplementation of the new kfifo API, which is now really generic, type save and type definable. The API is still stable, no code which use the current kfifo API must be modified!

It also includes some minor bugfixes and adds Documen... 27 Jan 2010 03:46
[PATCH v3 2/2] cpufreq: ondemand: Independent max speed for nice threads with nice_max_freq
Allow lower priority threads to scale frequency to specified nice_max_freq. This allows low priority threads to operate at the most efficient power/performance frequency.
