Dave Hansen 4031a219d8 smaps: have smaps show transparent huge pages 
Now that the mere act of _looking_ at /proc/$pid/smaps will not destroy
transparent huge pages, tell how much of the VMA is actually mapped with
them.

This way, we can make sure that we're getting THPs where we
expect to see them.
