Subject: [PATCH v2 0/2] fix and cleanup for iommu/vt-d

The first patch tries to improve the calculation of the dmar_domain first
level entry.

The second patch defines two marco for dmar_domains second level size and
shift instead of using an integer.

---
v2:
    * use DIV_ROUND_UP instead of ALIGN for the calculation.
      Thanks Robin Murphy <robin.murphy@....com>
    * adds patch 2 for comment


Wei Yang (2):
  iommu/vt-d: reduce extra first level entry in iommu->domains
  iommu/vt-d: use marco for dmar_domain's second level size and shift
