  Modified files:
    sys/alpha/alpha      pmap.c 
  Log:
  pmap_emulate_reference: don't ever lose PV_TABLE_MOD bit on page. If
  PV_TABLE_REF cleared before PV_TABLE_MOD, the page may get fault on read again.
  
  On fault on write, pmap_emulate_reference mark the page dirty with
  vm_page_dirty. That decrease ill effects of the bug.
  
  The problem probably become more serious after my rev.1.18 a week ago.
