Write Your Own 64-bit Operating System Kernel #2 - Stack, long mode and printing using C code

In the second episode of this series, we setup a basic stack, enable long mode, setup basic paging, and write some C code that prints any text onto the screen.

All the code is available on GitHub: https://github.com/davidcallanan/yt-os-series/tree/ep2
