Kernel: Add a heap memory allocator This is the first time I've actually dropped liballoc in favor of writing my own implementation. Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job. But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code! 2022-11-20 15:15:26 +01:00			`#pragma once`
