[KERNEL][6.0.1] Judo Chop! Kernel for Galaxy Tab E 9.6 SM-T560NU running TouchWiz MM

Judo Chop! Kernel for Galaxy Tab E 9.6 SM-T560NU (Snapdragon 410)
** BY FLASHING THIS KERNEL YOU ASSUME ALL RISKS TO YOUR DEVICE!!!
** BOOTING WITH THIS KERNEL INSTALLED WILL TRIP YOUR KNOX COUNTER AND MAY VOID YOUR WARRANTY
** PRACTICE SAFE FLASHING AND BACKUP YOUR DEVICE WHILE YOU CAN
** HAI KARATE SEZ: BE CAREFUL HOW YOU USE IT!
This kernel is for the Samsung Galaxy Tab E 9.6 SM-T560NU (Qualcomm Snapdragon 410) running TouchWiz Marshmallow 6.0.1. It is based on the T560NUUES1BPL1 source code, and most of the features were ported from corsicanu's hadesKernel 2.5 source code. The vast amount of the credit for this should go to him and, by extension, to those who contributed to his kernel.
After comparing my Tab E 9.6 with my wife's Tab A 8.0 and seeing the Tab E's woefully inferior colour fidelity, I set out to compile a permissive kernel with KCAL support (I bump the saturation up to 40, by the way) but when I found corsicanu's source code I incorporated as many of his features as I could.
Some supported features:
KCAL colour calibration
Adreno Idler 1.1
USB fast charge
intelli_thermal 3.0
Powersuspend
Prima WLAN driver
SELinux permissive
init.d support
Frandom
ZEN/SIO/FIOPS IO schedulers
ADB insecure
DM-Verity disabled
Various optimizations
Compiled with Uber Toolchain 4.9
Sorry, this kernel DOES NOT and CAN NOT support the Spreadtrum-based SM-T560. The architecture is completely different.
Kernel Adiutor is the only app I have tested for adjusting the various settings of this kernel.
To install, download the .zip file and flash it in your custom recovery of choice. I have only tested this with the TWRP 3.0.2-0 version created by ashyx.
