Dave Hansen suggested a new scheme to encode the data structure,
because of additional complexity, it's not implemented in v3.

FWIW, I don't think it takes any additional complexity here, at least in the
guest implementation side.  The thing I suggested would just mean explicitly
calling out that there was a single bitmap instead of implying it in the ABI.

Do you think the scheme I suggested is the way to go?

Yes, I think so.  And I will do that in the later version. In this V3, I just want to solve the 
issue caused by a large page bitmap in v2.
