Subject: kill warnings when building mandocs

This patch shuts warnings of the sort:

make -C /mnt/samsung_200/sam/kernel/trees/21-rc6/build \
	KBUILD_SRC=/mnt/samsung_200/sam/kernel/trees/21-rc6 \
	KBUILD_EXTMOD="" -f /mnt/samsung_200/sam/kernel/trees/21-rc6/Makefile mandocs
make -f /mnt/samsung_200/sam/kernel/trees/21-rc6/scripts/Makefile.build obj=scripts/basic
make -f /mnt/samsung_200/sam/kernel/trees/21-rc6/scripts/Makefile.build obj=Documentation/DocBook mandocs
  SRCTREE=/mnt/samsung_200/sam/kernel/trees/21-rc6/ /mnt/samsung_200/sam/kernel/trees/21-rc6/build/scripts/basic/docproc doc /mnt/samsung_200/sam/kernel/trees/21-rc6/Documentation/DocBook/wanbook.tmpl >Documentation/DocBook/wanbook.xml
  if grep -q refentry Documentation/DocBook/wanbook.xml; then xmlto man -m /mnt/samsung_200/sam/kernel/trees/21-rc6/Documentation/DocBook/stylesheet.xsl -o Documentation/DocBook/man Documentation/DocBook/wanbook.xml ; gzip -f Documentation/DocBook/man/*.9; fi
Note: meta version: No productnumber or alternative     sppp_close
Note: meta version: No refmiscinfo@class=version        sppp_close
Note: Writing sppp_close.9
Note: meta version: No productnumber or alternative     sppp_open
Note: meta version: No refmiscinfo@class=version        sppp_open

by adding a RefMiscInfo xml tag in the form of the current kernel version
to the function, struct and enum definitions in files included by
kernel-doc when building 'mandocs'.  However, the version string appears
truncated on the manpage due to some constraints in the xml DTD for the man
header, I believe, for the troff output is truncated too.
