[KERNEL][OOS 3.x.x/OldDroid's AOSP] Arsenic.Kernel-V10 (06/12/2016) - OnePlus X Android Development

Hi Folks!
So here is the gift i was working on! Here I present you Arsenic.Kernel for Oxygen OS and OldDroid's AOSP. Rebased to new source released by OnePlus, Some features "might" be different from cm/aosp version starting with the new naming convention (changed from "release" to "version") for these builds.
Made this Separate thread for OOS builds for better user experience and easier debugging of reports.
If you are running a Custom Kernel already then plz CLEAN FLASH Oxygen OS before flashing Arsenic, official zip doesn't offer system wipe so dirty flash wont work, you gotta clean flash manually!
Zip doesn't offer any module changes and doesnt mess with the ramdisk so you can feel free to dirty flash it over Arsenic's previous versions( Dont forget to clear data of kernel adiutor or anyother kernel control app you're using before ).
Keeping op short and simple and with keeping New users in mind, here is a brief description about kernel:

Bugs and issues:
Little longer Boot Time as compared to stock kernel - working to decrease it! (cant you wait a couple of secs. to boot? it should only bother those people who reboot every hour. lol)

F.A.Q's :
Can you add [this] and [that] feature to arsenic?
Something I pride myself with this kernel is that it does not have a bunch of random, useless features or patches mashed into it. Everything put into this kernel is thought out well and tested. I see a lot of works being made popular because it has [this] and [that] feature when really, it's nothing revolutionary(atleast to me). As a matter of fact, most things added to any kernel will not make it 5x better than any other kernel. Most of the time, simple is better; and in this case it definitely is!
Any plans of upstreaming the linux version?
No, and i wont. Though i have test builds ready but they wont make up to the release version. Upstreaming linux version doesnt make much difference infact it does degrade Arsenic's performance. Reason why i'm against it is that I've removed almost all possible useless redundant code and debugging present in it to improve kernel in all aspects, upstreaming will not only add alot of redundant code but will also add debugging functions for those redundant code! Which will not only increase kernel's size but will heavily impact on kernel's performance, battery backup and stability. Currently 3.4.0 is "THE" most stable branch and i'd like to keep it.
Why MPDecision? Why not remove the hell outta it?
You want me to remove something which was developed by some of the finest engineers of this world and is currently being shipped on almost all android devices..? Dont you think there would have been a reason why Google chose MPDecision over anyother hotplug.
What most of the users arent aware of is that, MPDecision works best with the default thermal solution, all it needs is a little touch..
As far as adding an additional hotplug, m still thinking about it.
Why so rude?
Not rude, Determined. Everything i do has a reason behind it. And I do sometimes accept feature request if they seems to be worthy.

Open Twrp > Wipe system,data,cache > Flash Oxygen OS > Reboot > Open Twrp > Flash Supersu > Reboot > Open Twrp > Flash Arsenic Kernel > Reboot.
OOS is not like a custom rom so to be on a safer side follow the above procedure.
You can dirty flash the future releases though, but if you are coming from anyother kernel then follow these above steps to avoid any conflicts.

Kernel is great Nimit few days now running like a champ!!

So what is fast charging? Afaik our charger gives max of 1800 mA, so can you explain it a bit?

By default hardware restricts USB charge current to <500 mA when connected to a PC/laptop, USB Fast charging driver syncs it with AC charge current rate.
Though rate varies accordingly to load average and device usage. Its managed by system for better result instead of forcing with a predefined value.

other custom kernels might leave postboot scripts and modified ramdisk which might conflict so, its better to clean flash.

Flash it working perfectly.

Any recommended gaming settings for kernel? (no lags using current settings but slight heat)

Just set minimum freq of gpu to 200Mhz instead of 27Mhz for gaming.
And its "OnePlus X", do you really expect it not to heat even while playing games?
Even if i add some custom thermal solution it will impact on UX while playing games as it will try to throttle CPU to control heat which might bug you lol
