This series introduces a pool of memory analogous to the shadow/HAP pool,
accounted to the guest domain, from which IOMMU page-tables are allocated.

Paul Durrant (5):
  libxl: remove separate calculation of IOMMU memory overhead
  iommu / domctl: introduce XEN_DOMCTL_iommu_ctl
  libxl / iommu / domctl: introduce XEN_DOMCTL_IOMMU_SET_ALLOCATION...
  iommu: set 'hap_pt_share' and 'need_sync' flags earlier in
    iommu_domain_init()
  x86 / iommu: create a dedicated pool of page-table pages
