KERNEL [OP5T] [OOS 8.0.0/CUSTOM 8.1.0] [4.4.112] [CLANG 6.0] Flash Kernel v3.0X

Introduction

Hello everyone, this is my personal kernel for the OnePlus 5T. While I am not a super star kernel developer, I do know my way around it. My philosophy on kernels is pretty simple:[list]

Follow stable Linux always. Updates will be delivered within 24 hours of their release to kernel.org.
Stable kernel rules work best (only add small things when possible).
Security and stability are paramount. Vulnerabilities are patched as soon as they are disclosed.
Features will be added only as needed (I have a list of things in the FAQ I will NOT add, even if requested).

Hopefully you enjoy

Couple of quick notes: I do not currently own a OnePlus 5T (I own a OnePlus 5) but I have a couple of reliable testers and the tree is unified so there should be no issues. Since the builds are unified, the zip name and kernel version will show OP5.

Important thread information!

I refuse to acknowledge/respond to bug reports that do not include clear steps to reproduce, a logcat, and a console ramoops (if random rebooting) or a dmesg (any other issues). Follow this guide to do this.
Keep things civil, I do NOT tolerate flaming of any kind.
OT is allowed.

Downloads

Primary: http://nchancellor.net/downloads/kernels/op5
Mirror: https://github.com/nathanchance/fk-zips

Folder descriptions:

alpha: Very likely broken or contains highly experimental patches; should only be run if you want to be a part of cutting edge development
beta: Normal testing build; bootable and has no immediate issue.
rc: Same as a beta but has had no issues for at least three days. I recommend running these when they are out as they will be pushed to the stable folder after a few days.
stable: Same as rc but has had no issues for at least three days. If you are unsure which one to run, just use this one.
archive: Old stable kernels

All issues with any build other than a stable build MUST be reported via Telegram. I keep my development out in the open but I don't let it cross over onto XDA. I do recommend participating as I am quicker to fix issues if I have multiple people testing. I request that you do not mirror my kernels. If the primary site is down, please use the mirror. Navigate to the file you want and click the download button. If you are mobile, tell GitHub to use the desktop version. I don't need posts telling me the primary site is down, it's my build server so I'll know if it is down. Thanks!

Frequently asked questions
1.1 Q: I am having an issue, can you help me?
1.1 A: I am not an amazing kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue, following this guide. If I can't reproduce reliably, I'm not going to fix the issue.

1.2 Q: Can you add xyz feature?
1.2 A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I will not go digging super hard for commits and I will ignore requests that don't include this information. I won't promise that I will merge every request but I will always take it into consideration. I will NOT add the following:

Overclocking or underclocking of CPU or GPU
Undervolting
Any governors other than interactive
Any schedulers other than cfq and maple
Anything that compromises performance

1.3 Q: How do I control the kernel?
1.3 A: I'd recommend using either @flar2's EX Kernel Manager or @Yoinx's Kernel Adiutor-Mod; both are extremely solid and have given me no issues.

1.4 Q: OMFG MY BATTERY SUXXXX PLS FIX!!!
1.4 A: The kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone.

1.5 Q: I am not getting notifications on OOS, what is the cause?
1.5 A: Disable advanced optimizations in Settings > Battery > Battery optimization > Three menu dots.

Thanks to:
The various other developers for their patches
@osm0sis for AnyKernel2
@adinkwok for being a bro
@Mazda for testing the build!
@phantom146 for the thread banner
All of you guys for viewing the thread

A note about donations

Quite a few people have asked to donate to me in the past and I have turned them down. I am not in this for the money, this is my hobby, something I truly enjoy. If you truly want to donate to something (it is not expected in the slightest), I recommend an entity like the Open Source Initiative, the Free Software Foundation, XDA, or any one of the people I have thanked in the OP. Additionally, you are free to copy any and all of my work; the only thing I request is that you not ask for donations as well (though I can't really enforce this lol). Thank you.
