It's appropriate, because in this context, we return page information
including addresses that would be valid pointer references, but are not
included in the core file.  Minidumps omit large numbers of physical pages,
so calls to kvm_walk_pages() will generate large numbers of kvm_page
instances that have an offset of -1.
