I'm by no means a pro at kernel building but I've put lots of effort into this kernel so I thought I'd share it with you. After a very long inner conflict period I've decided to post in the android development forum instead of the original android development. I've included features of my own as well as patches and other features of many other top notch kernel developers. I would prefer if you make your way over to my source (link below) and read the commits so you can get to know them and how they have contributed but alas I not that naive enough to think any of you really would actually go and do that so I've included a nice feature list in post 2 with proper credits (at least for the big stuff).
I am a huge fan of giving you options which is why I build my kernel with multiple toolchains for you to test out and decide which option you find works best for you. You'll notice that besides my two favorite toolchains (Linaro 4.9 and SaberMod 4.9.3) I also build a Google 4.8/4.9, SaberMod 4.8/4.9, Linaro 4.9 kernel about once a week or so. Give them all a try and decide which you like best!
I also made a Release Folder that contains kernels that do not contain any CPU or GPU overclock to keep things more stable for you. This kernel is built with SM 4.9.3 since I feel like that give the best battery. Choose this option for stability.
I frequently get asked if this kernel works with the many AOSP projects. The answer is YES! I haven't found an AOSP ROM yet that won't boot with this kernel. The only potential issue is that the ROM you flashed this kernel with has modified the ramdisk from stock or doesn't have a root containing sepolicy for Lollipop. Make sure to flash back to a stock ROOTED kernel and then flash UBER. My kernel uses you ramdisk while flashing for great ROM compatibility but sometimes this backfires.
Do not flash on CM or CM-based ROMs! This kernel is not currently compatible with those "CAF-based" ROMs.
WARNING!!! Even though I don't post anything unless it works (in this case on most if not all AOSP ROMs) I still don't want to be liable for user errors. In other words, if you flash one of these Kernels your warranty is void and I AM NOT RESPONSIBLE for any data loss or bricked devices etc.

(Not a feature but I feel it is important that my source is complete so you can build directly from it if you want to learn and experiment)
1. For best results a install these kernel after a fresh ROM install (although it still should work if you don't do that)
2. Reboot into recovery (TWRP 2.8+ or compatible recovery)
3. Flash Kernel Zip
4. Reboot and let Settle for ~10 minutes (optional but recommended)
5. Navigate to system/etc/uber_v1.3.cfg using your favorite root file browser and change values based on descriptions to whatever you want.
Note: In Android Lollipop while Superuser kinks are still being worked out you may need to reflash root after you flash kernel.
SPECIAL THANKS TO:
Dennis Rassmann - for all of his kernel work. I'm in love with all of his features and you'll find them all in my kernel.
Ayysir - for his wonderful tutorial on making a bash script to build kernels.
Other great kernel devs - I cherry-pick work of all of the kernel greats!
Google - for kernel base and AOSP!
LG - for manufacturing this awesome phone!
