    sys/amd64/amd64      pmap.c 
    sys/i386/i386        pmap.c 
  Log:
  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.
