Subject: [PATCH v3 1/3] docs/mm: Physical Memory: remove useless markup

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

Jon says:

  > +See also :ref:`Page Reclaim <page_reclaim>`.

  Can also just be "See also Documentation/mm/page_reclaim.rst".  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.

Remove reference markup and unnecessary labes and use plain file names.

Fixes: 5d8c5e430a63 ("docs/mm: Physical Memory: add structure, introduction and nodes description")
