<pre>Given the decode priority on our GMCHs, it's fine if the regions overlap.
However it doesn't look like there's a nice way to detect it. In this case,
part of the range occupied by the stolen space is simply "reserved" per the
E820, but the rest of it is under the bus 0 range (which kind of makes sense
too).
So I guess the gen3 hack is fine, unless we want to get fancy and check for a
bus 0 allocation and sub-allocate under that. Daniel, do you want to push it?</pre>
