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.

x86_64/MMU: Map the kernel page directory to virtual memory
...
This avoids depending on the kernel address space to create a new userspace one,
since there is no physical memory access.
This was fine for a single process, since its address space was created from the kernel one
and no more address spaces were created,
but for two or more, this started to become problematic, since we would create one address space
while being in another process's address space, which has no direct mapping of physical memory.
