Kernel: Do not stop interrupts by default in the interrupt handler
...
I always knew you can choose if interrupts are enabled for a specific ISR in the IDT entry, but at some moment there was a bug and I thought maybe that fixed it. Now reverting that doesn't break anything, so... let's do it :)

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
