LuPuS Kernel

Hello there, I was reading about Governors on a thread (http://forum.xda-developers.com/showthread.php?t=1369817)
and was curious about these governors that I hadn't seen before and wanted to try them.
So then I came across this (http://forum.xda-developers.com/showthread.php?t=1631754) great thread by paxChristos and decided I would try compile a kernel with new Governors and io-scheduler.
I've taken out a couple of things while compiling the kernel as well. I have been using it for a good few days now
and thought I should share these Governors to other Xplay users.
I googled for a name and came across LuPuS http://forum.xda-developers.com/images/smilies/highfive.gif that is why the boot logo is what it is http://forum.xda-developers.com/images/smilies/cool.gif
Well hope you all enjoy and I will be adding more governors soon when I get timehttp://forum.xda-developers.com/images/smilies/biggrin.gif
Thanks to all those who have helped me making this, paxChristos for his advice & tutorial.

What Works --
Wifi - (flash modules)
Video Recording (480p)
Video Playback
Front Camera
Everything Else that works on FXP & Mjolnir

What doesn't work --
Anything that doesn't work on FXP & Mjolnir

Added Governors --
Intellidemand - Thanks to faux123 (http://forum.xda-developers.com/showthread.php?t=1628610)
This is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling,
and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such.
Intellidemand does not jump to highest frequency when screen is off.

Lazy - Thanks to Ezekeel (http://forum.xda-developers.com/showthread.php?t=1355980)
The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand.
Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state
on a step overriding sampling interval.
Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always
select the maximum frequency while the screen is off.

Lulzactive - Thanks to Tegrak (http://forum.xda-developers.com/showthread.php?t=1118918)
Based on Interactive and Smartass. When workload is greater than or equal to 60%, the governor scales up
CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step.
When screen is off, frequency is locked to global scaling minimum frequency

Added Io-scheduler --
VR io-scheduler - Unlike other schedulers, synchronous and asynchronous requests are not treated separately,
instead a deadline is imposed for fairness. The next request to be served is based on it's distance from last request.
