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.

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.Signed-off-by: FUJITA Tomonori
