    sys/vm               vm_map.c device_pager.c 
  Log:
  Fix a device pager leak for the case where the page already exists in the
  VM object (typical case: multiple mappings of the device?).  If the page
  already exists we simply update its physical address.  It is unclear whether
  the physical address would ever actually be different, however.
  
  This is an untested patch.
