This is my custom kernel for learning purposes. I'm not a osdev at all, so please excuse the mess.
Right now it compiles for x86_64, 32-bit is not supported. Most of this is just skeleton code from osdev.org, but I cleaned some stuff. I use Stivale for higher half kernel loading and not having to gaff about a bootloader for now. Limine is included as my bootloader of choice.
