Claim 17:
18. A non-transitory computer-readable storage medium that stores instructions readable by a processing system to cause the processing system to:
receive a request to translate a virtual address into a physical address associated with a physical memory page in a memory of the processing system;
perform a table-walk through page tables of a page table set for the physical memory page, wherein the table-walk first accesses a non-extended page table and subsequently accesses an extended page table of the page table set using a same set of bits from the virtual address; and
based on accessing the extended page table, retrieve an extended page attribute from an extended page table entry of the extended page table, wherein the extended page attribute includes at least a subset of the physical address of the physical memory page.
