  To: linux-doc, linux-mm; +Cc: Matthew Wilcox (Oracle)

From: "Matthew Wilcox (Oracle)" <willy@infradead.org>

The documentation currently does not include the deathless prose
written to describe functions in pagemap.h because it's not included
in any rst file.  Fix up the mismatches between parameter names and the
documentation and add the file to mm-api.
