pmap_enter vs pmap_qenter

    pmap_kenter() and pmap_qenter() enter the pages into the pmap unmanaged,
    meaning it just stuffs the pte's and doesn't track and pv_entry's.

    pmap_enter() enters the pages into the pmap managed.

    I think that has something to do with how the pages have to be removed
    later on when the block is freed.
