Flight NRT-PVG-DPS confirmed, w/ 8hr stopover

I can see that Norway is not on your list, but according to the Chinese Embassy in Norway norwegian citizens are also eligible for a visa-free transit entry. Can you confirm this?

My question is: I've got a routing NRT-PVG-DPS confirmed with China Eastern, with a stopover in Shanghai for about 8hrs.. Will I need to get the permit registered at a local police station if the stay in Shanghai city is under 8hrs?
