Instead of an all or nothing approach add support for requiring
restricted memory access per device.
Changes in V3:
- new patches 1 + 2
- basically complete rework of patch 3
Juergen Gross (3):
virtio: replace restricted mem access flag with callback
kernel: remove platform_has() infrastructure
xen: don't require virtio with grants for non-PV guests
Any further comments?
