ba22931235 docs/vm: move ksm and transhuge from "user" to "internals" section.
After the userspace interface description for KSM and THP was split to
Documentation/admin-guide/mm, the remaining parts belong to the section
describing MM internals.

1174bd849c docs/vm: numa_memory_policy: s/Linux memory policy/NUMA memory policy/
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.

24844fd339 Merge branch 'mm-rst' into docs-next
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.
