Jonathan, what is your idea about the placement of doc files?

After some considerarion, I have a new idea. Since the top charpter named as
*API* so non-API things is not suitable for this charpter. But can we just
rename it? For example, we can rename 'Kernel API documentation' to 
'Subsystem-specifc documentation' which is similar to 'Architecture-specific documentation'?

Subsystem-specifc documentation
-------------------------------
.. toctree::
   :maxdepth: 2

   driver-api/index
   core-api/index
   media/index
   networking/index
   input/index
   gpu/index
   ...

Architecture-specific documentation
-----------------------------------
.. toctree::
   :maxdepth: 2

   sh/index
   x86/index
   ...
