Not really. pte_free and pmd_free are called from the common mm code but
the concept of empty_bad_{pte,pmd}_table is architecture dependent. The
trouble starts in arch/???/mm/init.c where these special arrays are
inserted into the paging tables. So the solution to the problem should be
in architecture dependent files too.
