xen: introduce xen_dma_map/unmap_page and xen_dma_sync_single_for_cpu/device Introduce xen_dma_map_page, xen_dma_unmap_page, xen_dma_sync_single_for_cpu and xen_dma_sync_single_for_device. They have empty implementations on x86 and ia64 but they call the corresponding platform dma_ops function on arm and arm64. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Changes in v9: - xen_dma_map_page return void, avoid page_to_phys.
