  Modified files:
    sys/vm               vm_map.c 
  Log:
  Correct an error in the previous revision that could lead to a panic:
  Found mapped cache page.  Specifically, if cnt.v_free_count dips below
  cnt.v_free_reserved after p_start has been set to a non-NULL value,
  then vm_map_pmap_enter() would break out of the loop and incorrectly
  call pmap_enter_object() for the remaining address range.  To correct
  this error, this revision truncates the address range so that
  pmap_enter_object() will not map any cache pages.
