While for DomU's the initial memory map clearly cannot be expected to be
contiguous in MFN space, currently it happens to be that way for (x86)
Dom0 (and even the !NDEBUG case only intentionally breaks this for the
space beyond v_end).

Without a formal guarantee it would seem fragile, however, to rely on
this. Thus the question is whether it's reasonable to document such a
behavior, or whether instead any such assumption should be forcefully
broken by the Dom0 builder.

Thanks, Jan
