Not sure what it's supposed from me to do. The forward declarations are
the tighten part of the cleanup (*) and it's exactly what is happening here,
i.e.  replacing kernel.h "with the list of what is really being used".

*) Either you need a header, or you need a forward declaration, or rely on
   the compiler not to be so strict. I prefer the second option out of three.
