Line 53:
The second step is to create a basic page table. In this example we choose to fill up the whole first page table with addresses for the MMU. Because each page is 4 kilobytes large, and because each page table has exactly 1024 entries, filling up the whole table causes us to map 4 megabytes of memory.
We start like we did with the page directory, by finding a piece of free memory where we can keep our page table. If we properly page-aligned the page directory, then the page table should also be properly page aligned.

//our first page table comes right after the page directory
