Subject: [PATCH 2/2] docs/mm: remove useless markup

From: "Mike Rapoport (IBM)" <rppt@...nel.org>

It is enough to use a file name to cross-reference another rst document.

Jon says:
  The right things will happen in the HTML output, readers of the
  plain-text will know immediately where to go, and we don't have to add
  the label clutter.

Drop reference markup and unnecessary labels and use plain file names.
