It's just a hook you already have for Xen-specific stuff in QEMU.

Why the question marks? :)
If you have 4GB of RAM it will end at 0x140000000 (or something like
that) and that's where the 64-bit window starts. Of course if you have
no RAM above the PCI hole, the 64-bit window will start at 0x100000000.
