I'll have to take a look, I'm not sure if custom linker scripts are
inherited from upstream qemu. We certainly used to use one for 32-bit x86 so
that we could 1:1 map as much guest physical memory as possible. That need
has gone away with the mapcache, and anyway virtual address space was never
a limiting factor for 64-bit architectures in the first place.
