 Another important thing that we already know is that usually any memory right after the kernel is usually free, and if it is not is because something is loaded there, and we should be able to tell it by parsing some data structures provided by grub (the memory map, and the modules). At this point we can safely assume that unless the addresses above the end of the kernel are reserved in the mmap, or used by some module (and that can be easily achieved by parsing the tables already present in memory), that area can be used.
 
-And here is the solution, until the memory maanger is not initialized, we will keep returning addresses that are just after the kernel for creating the page tables required for the `hhdm` Initialization (again with the exclusion of the parts that we already knows are marked as used by the bios/bootloader).

 Once the _hhdm_  is initialized, we proceed with the PMM Initialization, but now reassured that we will not encounter any unexpected memory mapping, because we will use the memory map just initialized.
