When I tried to add this update site this morning, I got the following message: Could not find http://www.eclipse.org/downloads/linuxtools/updates-nightly-kepler
I think "http://download.eclipse.org/linuxtools/updates-nightly"; is the correct update site, so I tried that, and the update did work. But after Eclipse restarted, I no longer have a "Profiling Tools". I pinged my colleague, Rodrigo, on the side, and he thinks it's probably because this oprofile plug-in update has Java7 dependencies, and I'm on Java6. He updated his oprofile plug-in and said the 'count' field now works properly, so that's good enough for me.
