There has always been an overlap between the main and the notes
segment; there being only two segments I don't see any other
potential for an overlap. In fact I can't see anything other than size
differences between a 4.8.1 and a 4.9 binary, plus of course the
base address change resulting from Daniel's EFI/GrUB2 patches. So
I'm rather puzzled as to what effect Jürgen's patch could have had
on the behavior of any loader whatsoever.

The only possibly misleading section I notice is .reloc, but that's
present in xen-syms only, not in xen.gz. And again it's a result of
Daniel's series, not Jürgen's patch.
