Claim 11:
12. A method, comprising:
receiving, at a memory management unit of a processing system, a request to translate a virtual address into a physical address associated with a physical memory page in a memory of the processing system;
performing a table-walk through tables of a page table set for the physical memory page to identify an extended page table of the page table set, wherein a first page table accessed by the table-walk is a non-extended page table of the page table set and a last table accessed by the table-walk is the extended page table; and
based on a same set of bits of the virtual address, accessing a pointer to the extended page table in a non-extended page table of the page table set and, from the extended page table, retrieving an extended page attribute associated with the physical memory page based on the pointer, wherein the extended page attribute includes at least a subset of the physical address of the physical memory page.
