    sys/i386/i386        pmap.c 
  Log:
  Fix a hideous TLB bug.  pmap_unmapdev neglected to remove the device
  mappings from the page tables, which were mapped with PG_G!  We could
  reuse the page table entry for another mapping (pmap_mapdev) but it
  would never have cleared any remaining PG_G TLB entries.
