| 2008-03-05 | iommu: export iommu_is_span_boundary helper function | FUJITA Tomonori | |
| iommu_is_span_boundary is used internally in the IOMMU helper (lib/iommu-helper.c), a primitive function that judges whether a memory area spans LLD's segment boundary or not. It's difficult to convert some IOMMUs to use the IOMMU helper but iommu_is_span_boundary is still useful for them. So this patch exports it. This is needed for the parisc iommu fixes.

| 2008-02-05 | iommu sg: add IOMMU helper functions for the free area management | FUJITA Tomonori | |
| This adds IOMMU helper functions for the free area management. These functions take care of LLD's segment boundary limit for IOMMUs. They would be useful for IOMMUs that use bitmap for the free area management.
