2023-06-23hw/virtio: Remove unnecessary 'virtio-access.h' headerPhilippe Mathieu-Daudé
None of these files use the VirtIO Load/Store API declared by "hw/virtio/virtio-access.h". This header probably crept in via copy/pasting, remove it. Note, "virtio-access.h" is target-specific, so any file including it also become tainted as target-specific.

2023-01-08vdpa-dev: get iova range explicitlyLongpeng
In commit a585fad26b ("vdpa: request iova_range only once") we remove GET_IOVA_RANGE form vhost_vdpa_init, the generic vdpa device will start without iova_range populated, so the device won't work. Let's call GET_IOVA_RANGE ioctl explicitly.
