what? - The main algorithm got improved for real time tasks, and SMP usage. - The SMP usage was present before, I just reintroduced it after realizing that it won't scale well from what I have right now. - Also removed weird implementations quirks from previous sketch. - Such as the core 0 being reserved for the boot core. - Also moved FS init code after IDT initalization. - To avoid weird FS format behavior. - Wrap HPET signature in a macro. next? - Work on the HAL's userspace transition mechanism.
