Subject: [PATCH 01/11] DOC: convert 'subsection' to 'section' in gfp.h

Various DOC: sections in gfp.h have subsection headers (~~~) but the
place where they are included in mm-api.rst does not have section, only
chapters.
So convert to section headers (---) to avoid confusion.  Specifically if
section are added later in mm-api.rst, an error results.
