This still has a few problems. Notably, we are not using huge pages for this mapping, which would be a lot more efficient.
Right now, used memory is 8.1 MiB at boot for a 256MiB system.
But after improving it, this system will be much better than recursive mapping.
fork() will be MUCH easier to implement, for example.
