I was actually just about to send a defconfig cleanup patch set.  My 
tests are all still a bit broken, so I'm going to hold off on sending 
the defconfig cleanups until I can get them back together.  This is so 
simple that anything it could break would already be broken, so I'm just 
going to take it now.

This is on fixes.

Thanks!
