Alex, moving kdump to admin-guide sounds reasonable to me.  I also agree
with you for those arch dependent files can be moved to
Documentation/arch/, maybe you are talking about some other patches in
the series for the arch/?

Alex,

It makes sense for me to have a Documentation/arch directory, and place
the arch-specific docs over there.

There's actually a technical advantage on doing that: Sphinx is dumb
with regards to PDF/LaTeX output: it requires all top documents to be
listed at Documentation/conf.py, under this var:

	latex_documents = [
		...
	]

As it creates one runtime Makefile at Documentation/output per listed
document there. So, the more we group such documents, the less merge
conflicts we'll have at Documentation/conf.py.

Btw, there's a [TECH TOPIC] proposal for KS/2019 meant to discuss 
Documentation.

I suspect we could discuss the pros/cons of doing such change there.

My personal view is that we should keep the Documentation/ root dir as
clean as possible as a long term goal.

On the other hand, it makes the path bigger and harder to rename.

On a side note, last time we discussed documentation at KS I remember
I proposed to shortcut "Documentation/" to just "docs/". The consensus
on that time were to keep the big name. I still think that a shorter
one could help people to remind where documentation will be located.

Thanks,
Mauro
