    sys/i386/i386        pmap.c 
  When support for 2MB/4MB pages was added in revision 1.148 an error was
  made in pmap_protect(): The pmap's resident count should not be reduced
  unless mappings are removed.
  The errant change to the pmap's resident count could result in a later
  pmap_remove() failing to remove any mappings if the errant change has set
  the pmap's resident count to zero.
