The idea is, the pmap_qenter() API is now defined to not produce executable mappings. If you need executable mappings, use another API. Add pg_nx flag in pmap_qenter on x86 to make kernel pages non-executable. Other architectures that support execute-specific permissons on page table entries should subsequently be updated to match.
