  MFamd64/i386 r207205
    Clearing a page table entry's accessed bit and setting the page's
    PG_REFERENCED flag in pmap_protect() can't really be justified, so
    don't do it.
  
  Additionally, two changes that make this pmap behave like the others do:
  
  Change pmap_protect() such that it calls vm_page_dirty() only if the
  page is managed.
  
  Change pmap_remove_write() such that it doesn't clear a page table
  entry's accessed bit.
