[PATCH] kernel-doc: warn on malformed function docs.



When the verbose (-v) option is used with scripts/kernel-doc, this option
reports when the kernel-doc format is malformed and apparently contains
function description lines before function parameters.  In these cases, the
kernel-doc script will print something like: Warning(filemap.c:335):
contents before sections

I have fixed the problems in mm/filemap.c and added lots of kernel-doc to
that file (posted to the linux-mm mailing list Mon.  2006-June-12).

The real goal (as requested by Andrew Morton) is to allow the short
function description to be more than one line long.  This patch is both a
kernel-doc checker and a tool en route to that goal.
