I compiled this kernel for my OnePlus5T. After that, I packaged it with AnyKernel3 (I'm getting "Dumping/splitting image failed. Aborting...").

- TWRP-Version: 3.4.0-0 (No I didn't try any other version, because the pre-build ROM worked -> I assume I made a mistake).
Further notes: First time building / flashing a kernel, actually, first time I do anything this low level so you might need to explain a bit more thorough than normal.
