The way .modinfo is created is a kludge to prevent the .modinfo section
being loaded as part of the module.  The initial reference to .modinfo
creates it as non-allocated, later references try to allocate data in
the section.  Older versions of gcc silently ignored the mismatch,
newer ones warn about the mismatch.

modutils >= 2.3.19 makes sure that .modinfo is not loaded so the kernel
kludge is no longer required.  Alan Cox (quite rightly) will not force
2.2 users to upgrade modutils, but if you jump to modutils 2.3.23 and
apply this patch against kernel 2.2.18 then the warnings will disappear.
