I thought I did, turns out, I am struggling. I am planning on watching 
this video
http://video.linux.com/videos/applying-clang-static-analyzer-to-linux-kernel
but it is 30 min, and I am about to head off to work. I am also having 
some problems finding bugs, I saw that we should be looking in 
drivers/staging for bugs, Do we need to make changes to the .config to 
get those to show up in the tools (clang, smatch, sparse)? If so, are 
their any other changes?

I would like to compile all the info and tips I have been seeing into a 
web page. If anyone wants to add to the info, I am happy to hear advice.
