Subject: [PATCH v3 0/3] virtio: support requiring restricted access per device

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
