  SVN rev 182394 on 2008-08-28 18:50:09Z by marius
  
  MFC: r182122
  
  There's a race in kmem(4) between checking whether a page is resident
  in the kernel and copying it out, causing a panic when faulting on a
  nofault entry. Handle this case gracefully by letting the kernel copy
  functions return EFAULT instead. As such this change addresses the
  same problem as r154721 does for i386.
