Still in context above is the calculation for IOMMU page tables When iommu_hap_pt_share, why do we need to reserve extra space? If the IOMMU calculation isn't precise enough, perhaps that's what wants changing? Quite possibly it would suffice to simply double the value dom0_paging_pages() returns in that case.
