The pte quicklist and pmd quicklists need to be different. This is because
"empty" page tables and pmd tables are initialized to different values
(page tables are 0ed, pmd tables are made to point to invalid_pte_table),
hence these 2 different types of objects can not use the same list. Else
pmd_none and pte_none get confused.
