Looks good, but hard to tell if it is correct :P.

I like this qt-creator feature: "this header is not directly used, 
remove?". Maybe we could extend it to the kernel somehow (as it uses 
clang to decide, I suppose). As was shown recently, removing the 
inclusion hell can decrease the build time significantly…

Yes, that's what Ingo's gigantic patch series targeted, but seems no-one is
interested enough to get it through. clang people also wanted to have a tool
like checkpatch for the inclusions or even like coccinelle to just fix the
code, but it's a project with no deadline or milestones AFAIK.
