[PATCH 0/6] Minor improvements for pagewalk code

For some project I had to use the pagewalk API for certain things and during 
this have read through the code multiple times. Our usage has changed several 
times depending on our current state of research as well.

During all of this I have made some tweaks to the code to be able to follow it 
better when hunting my own problems, and not call into some things that I 
actually don't need. The patches are more or less independent of each other. 
Especially the last one may heavily depend on personal taste, so if you don't 
like it, just ignore it.

I would welcome if you could just pick those that you think are fitting and 
provide feedback on either of the remaining ones. At the end none of them 
should make any functional difference.

Regards,

Eike
