tools/memory-model: Move Documentation description to Documentation/README

Browse source 
This commit moves the descriptions of the files residing in
tools/memory-model/Documentation to a README file in that directory,
leaving behind the description of tools/memory-model/Documentation/README
itself.  After this change, tools/memory-model/Documentation/README
provides a guide to the files in the tools/memory-model/Documentation
directory, guiding people with different skills and needs to the most
appropriate starting point.

It has been said that successful communication requires first identifying
what your audience knows and then building a bridge from their current
knowledge to what they need to know. Unfortunately, the expected
Linux-kernel memory model (LKMM) audience might be anywhere from novice
to expert both in kernel hacking and in understanding LKMM.
This document therefore points out a number of places to start reading,
depending on what you know and what you would like to learn. Please note
that the documents later in this list assume that the reader understands
the material provided by documents earlier in this list.
o You are new to Linux-kernel concurrency: simple.txt
o You are familiar with the Linux-kernel concurrency primitives
that you need, and just want to get started with LKMM litmus
tests: litmus-tests.txt
o You are familiar with Linux-kernel concurrency, and would
like a detailed intuitive understanding of LKMM, including
situations involving more than two threads: recipes.txt
o You are familiar with Linux-kernel concurrency and the use of
LKMM, and would like a quick reference: cheatsheet.txt
o You are familiar with Linux-kernel concurrency and the use
of LKMM, and would like to learn about LKMM's requirements,
rationale, and implementation: explanation.txt
o You are interested in the publications related to LKMM, including
hardware manuals, academic literature, standards-committee
working papers, and LWN articles: references.txt
