parentunicore32: switch to generic version of pte allocation (diff)
mm/pgtable: drop pgtable_t variable from pte_fn_t functions
Drop the pgtable_t variable from all implementation for pte_fn_t as none of them use it. apply_to_pte_range() should stop computing it as well. Should help us save some cycles.
