Hi all, this patch series enables xen-swiotlb on arm and arm64. It has been heavily reworked compared to the previous versions in order to achieve better performances and to address review comments. We are not using dma_mark_clean to ensure coherency anymore. We call the platform implementation of map_page and unmap_page. We assume that dom0 has been mapped 1:1 (physical address == machine

This switches virtio to use the DMA API on Xen and if requested by module option. This fixes virtio on Xen, and it should break anything because it's off by default on everything except Xen PV on x86. To the Xen people: is this okay? If it doesn't work on other Xen variants (PVH? HVM?), can you submit follow-up patches to fix it? To everyone else: we've waffled on this for way too
