Kernel: MMU::get() is now MMU::kernel
...
MMU is can now be locked with RecursiveSpinLock.
Scheduler now has get_current_tid() that works before the Scheduler
is initialized. This allows RecursiveSpinLock usage early on.

Kernel: Remove offset from OpenFileDescriptor
...
This is now handled on the libc side. There might be reasons to
have it in kernel side, but for simplicity's sake I'm moving it
to libc for now :)

This is more appropriate name for the behaviour :D

Kernel: Process is not reference counted any more

This was not necessary and it made things needlessly complicated

Kernel: Reorder boot initialization
...
We now create the TTY as soon as possible so we can show console
output without serial port.

Kernel: kernel doesn't allocate large blocks of data on stack
...
We used to allocate 1 KiB blocks on multiple places on stack. This
is a problem, since kernel stack shouldn't have to be too big

We don't handle arrow keys, and the tty does not know how to clear
the screeen :D

Kernel: Start work on making tty a file
...
TTY is now a file that you can read from/write to. I still have
to port shell to use this new interface
