A first physical memory page is compared with a second physical memory page, wherein the first physical memory page is associated with a first page table and the second physical memory page is associated with a second page table. If the second physical memory page matches the first physical memory page, the second physical memory page is deallocated, and the second page table is associated with the first physical memory page.
