The document describes NUMA memory policy and as it is a part of the Linux
documentation it's obvious that this is Linux memory policy. Besides,
"Linux memory policy" may refer to other policies, e.g. memory hotplug
policy, and using term NUMA makes the documentation less ambiguous.

Several documents in Documentation/vm fit quite well into the "admin/user
guide" category. The documents that don't overload the reader with lots of
implementation details and provide coherent description of certain feature
can be moved to Documentation/admin-guide/mm.

"pagemap from the Userspace Perspective" is not very descriptive for

Mike Rapoport says:
These patches convert files in Documentation/vm to ReST format, add an
initial index and link it to the top level documentation.
There are no contents changes in the documentation, except few spelling
fixes. The relatively large diffstat stems from the indentation and
paragraph wrapping changes.
I've tried to keep the formatting as consistent as possible, but I could
miss some places that needed markup and add some markup where it was not
necessary.
