Paul's opinion seemed to be that with secret hiding coming along and destroying the "xenheap is mapped anyway" assumption, the benefit of allocating a xenheap page and then mapping it to a guest is basically gone *anyway*, so that part at least made a viable cleanup regardless of the overall direction. By the time we start making the IOMMU use domheap for *its* page table allocations because we want 'domheap ≡ preserved pages', yes I completely agree that we should have settled the overall direction and nomenclature first. But I'm inclined to agree with Paul that this part stands by itself as a cleanup regardless of that.
