Could someone please explain me how page table walking functions (file page.h) work? For instance, l4e_to_l3e. As far as I understand, l4e_to_l3e turns an entry of level4 page table into a virtual address that points to a level3 page table? Is that ok? How is that done in details? Where are the real page tables (l4 to l1) stored? More generally, is there any doc explaining the details in page.h ?.... thanks! Armand
