Editing Page table (section)

=== Virtualized page tables ===
It was mentioned that creating a page table structure that contained mappings for every virtual page in the virtual address space could end up being wasteful. But, we can get around the excessive space concerns by putting the page table in virtual memory, and letting the virtual memory system manage the memory for the page table.

However, part of this linear page table structure must always stay resident in physical memory in order to prevent circular [[page fault]]s and look for a key part of the page table that is not present in the page table.
