  MFC revision 1.546
    Eliminate unnecessary invalidations of the entire TLB by pmap_remove().
    Specifically, on mappings with PG_G set pmap_remove() not only performs
    the necessary per-page invlpg invalidations but also performs an
    unnecessary invalidation of the entire set of non-PG_G entries.
