Subject: [PATCH 0/3] IOMMU: move page number calculation to generic code
Date: Friday, July 25, 2008 - 5:57 am

This small patch series introduces a generic iommu_num_pages function into the
IOMMU helper code. This function can be used to calculate the number of pages
an IOMMU has to map for a specific mapping request.

The patchset converts the x86 IOMMU implementations for AMD IOMMU and the GART
to use this function.

Other IOMMU implementations are not changed because I can't test them.
