Is big offsets the intention of this patch? As far as I understood its
for small offsets (typical 64k - on debian, ubuntu, suse, fedora and all
the others - i checked it because it tested this), so address 0 will not
be used in typical linux configs today to grab null pointer exceptions.
As result of some commits, the patch currently does not apply anymore.
