f1a7138568 User mode (with a few syscalls)
IT ACTUALLY WORKS NOW.

Why wasn't it working? Oh, because I was not setting already present page tables's permissions to user mode. Just a little bug. THAT I SPENT DAYS TRYING TO FIND

Anyways, it works now. Such a relief...

6fc7608c35 main: remove kmalloc/kfree example 2022-09-24 23:18:44 +02:00
6bd3529f32 Port liballoc to get proper kmalloc/kcalloc/krealloc/kfree functions.
Yes, that's not completely-from-scratch.
But let's be honest, am I going to do everything from scratch? Probably not. I'm not making my own bootloader.
And making a proper smaller-than-4-KB allocator is not something I want to do.
Plus, liballoc works perfectly in this rewrite, seeing as the MM code actually works, instead of leaking all your poor memory
And liballoc_{lock, unlock} can be actually defined, since we have spinlocks here!

1c12cf016e Add a Scheduler.

Just Round Robin with sleeping, but it's still awesome. I think this can finish v0.3, with a few adjustments.
