We just set the present and writable bits (`0b11` is a binary number) in the aligned P3 table address and move it to the first 4 bytes of the P4 table. Then we do the same to link the first P3 entry to the `p2_table`.

Now we need to map P2's first entry to a huge page starting at 0, P2's second entry to a huge page starting at 2MiB, P3's third entry to a huge page starting at 4MiB, and so on.
