[PATCH 0/3] virtio: Clean up scatterlists and use the DMA API
This fixes virtio on Xen guests as well as on any other platform on
which physical addresses don't match bus addresses.
This can be tested with:
virtme-run --xen xen --kimg arch/x86/boot/bzImage --console
using virtme from here:
https://git.kernel.org/cgit/utils/kernel/virtme/virtme.git
Without these patches, the guest hangs forever. With these patches,
everything works.
