Hello,

The follow series aims to improve the time consumed to setup the IOMMU
for the hardware domain.

Patch 1 and 2 are prereqs, while patch 3 is the actual change that
speeds up IOMMU setup.  See patch description for figures.

Thanks, Roger.

Roger Pau Monne (3):
  amd-vi: use the same IOMMU page table levels for PV and HVM
  x86/iommu: move xen_in_range() so it can be made static
  x86/iommu: use a rangeset for hwdom setup
