Your warranty is now void.
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this kernel
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

/* FAQ */

What is arteractive CPU governor?
It is an interactive CPU governor port from Galaxy S5. It has more optimizations for Snapdragon 80x processors.
Why are other CPU governors disabled?
I personally don't want any of my users to play around CPU governors. It'll start be a mess when I try to add support for other CPU governors.
Can I use stock mpdecision and stock thermal engine?
This one too, I'd like my users to stick with intelli-plug and intelli-thermal. Stock implementation is faulty, cores can lock down with stock mpdecision. As for intelli-thermal, the benchmarking score may reduce but will help for a lower temperature of the device and increase the efficiency of the thermal control.
How can I switch to another or stock kernel?
You may have to reinstall the entire ROM. Wipe /system and install the ROM. The included addon.d script helps the kernel to survive on nightly upgrades, but you need to remove it or wipe /system to switch to another kernel.
