[KERNEL][WIP] Mason kernel for supersonic v0.14

This started as a project to bring sbc to the supersonic ICS aokp rom. However I decided to go ahead and move forward with moving over some of the fine work that is going on for the Nexus line and bring it over to our beloved evo4g. I want to stress that to my knowledge the things that will be included beyond what is in tiamat/CM9 proper are not very well tested on our platform.

The overwhelming goal is to bring performance and stability improvements to the supersonic platform. The original idea, had a little less scope. I have now broadened its scope to include ICS, GB, and even Sense soon. The project will actually breed a whole line of kernels built for the supersonic with the needs of it's community in mind. Let's breathe some new life into our platform.

Thanks to the evervolv team without which we wouldn't have ICS on the supersonic at the moment.

Kernel Features:

CPU Frequency governors: conservative, ondemand, ondemandX, interactive, interactiveX, smartass, smartassV2, intellidemand, SavagedZen, minmax, lulzactive, lazy, lagfree, userspace, powersave, Lionheart, brazillianwax

I/O Schedulers: deadline (flash optimized), vr, noop, cfq, bfq, sio

HAVS, KSM (I series), Ext2/3/4, NTFS

Variants:

nosbc - Standard kernel without sbc
sbc - Smart Battery Control
hwa - Hardware Acceleration
fso - File synchronization off

Note on FSO:

I provide this without any warranty at all (not that I do with anything else). Yes, fso makes things faster, it's for the speed hungry among you, however there is the potential, however slight that you can get corrupted data on a crash. Do not run this without a proper nand, it's just a bad idea. I haven't personally had any issues, but that doesn't mean that in theory it can't happen. It's a very strong possibility however slight it might be. The price you pay for speed I suppose.

Note on SBC:

There are some out there who find sbc and unholy abomination. Though again I have not experienced issues personally, there are some out there that claim that it can damage your battery, particularly the lifetime of the battery. There is data to support both sides of this argument, and I'm not here to go over all that. But be warned that it may cause some battery issues, and take care that you are both advised of the risks and willing to take them for some extra juice.

Side note:

I will try my hardest to maintain both this and the rootzwiki thread as time allows. That said let's keep the discussion pleasant and on the topic of bugs and features supersonic users would like to see either quashed or provided respectively. I feel bad for slightly hijacking the aokp and other ICS threads so lets move the kernel relevant conversation here.

Useful bug reporting:

* Include the Rom you are running.
* Include the kernel version you are running.
* Include any custom settings you have changed cpu governor/io scheduler/cpufreq scale etc.
* Include any tweak scripts you may be running.
* Include any voltage changes you might be running.
* Include what you expected to happen.
* Include what really happened.
* Include if you can reproduce the bug at will.
* Include logcat and/or any other logging mechanisms you might have available. OS Monitor is a fine choice.
* Include screenshots if possible/applicable.

Be as detailed as possible. Good bug reporting is a great way to add to the community, even if you aren't a developer, this is a excellent way to give back.

One more to be safe.

Any thoughts on ICS Sense kernel just in case cause theres ruu leaks so we might need one.

Ruu leaks alone won't be very helpful to kernel devs, we need code with which to play with. That said if/when sense kernel code hits for the supersonic, I will evaluate making a parrallel Mason for that. Most of my currently planned changes aren't are not specific enough to ASOP to prevent it.

I say most because there are a few things that I know for sure won't make it in without more hacking than I'm willing to do for sense atm.

Make no mistake, I'm a asop fanboy.

Would this be the same kernel you posted a day or two ago? I'm lovin it, the sbc helps a bunch

No though it did provide a base, of sorts.

Any chance of getting a bfq version or r we sticking with cfs for now on.

As far as I know bfq is supported in this kernel as is any number of other I/O govs. Check whatever you're using to switch them and see if it's a option. The bfq code needs some updating though, which I'll address at a later date.

I recommend deadline on the supersonic, particularly after my next version drops which has some improvements for deadline used with flash memory.

I'll make sure I add that option to change it in my script for all to enjoy

Right on, side note: just about anything that is tiamat based which is anything ics for the supersonic right now is going to have deadline. Maybe not the version that's going to drop in the am, but some type of deadline.
