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

[Wei Yang]

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.
