intel-iommu: add map_page and unmap_page

Browse source

This is a preparation of struct dma_mapping_ops unification. We use
map_page and unmap_page instead of map_single and unmap_single.

This uses a temporary workaround, ifdef X86_64 to avoid IA64
build. The workaround will be removed after the unification. Well,
changing x86's struct dma_mapping_ops could break IA64. It's just
wrong. It's one of problems that this patchset fixes.

We will remove map_single and unmap_single hooks in the last patch in
this patchset.
