[PATCH 07/25] block: Convert bio_for_each_segment() to bvec_iter
More prep work for immutable biovecs - with immutable bvecs drivers
won't be able to use the biovec directly, they'll need to use helpers
that take into account bio->bi_iter.bi_bvec_done.
This updates callers for the new usage without changing the
implementation yet.

[PATCH v3 4/8] vringh: support VA with iotlb
vDPA supports the possibility to use user VA in the iotlb messages.
So, let's add support for user VA in vringh to use it in the vDPA
simulators.

[PATCH v3 0/8] vdpa_sim: add support for user VA
This series adds support for the use of user virtual addresses in the
vDPA simulator devices.
The main reason for this change is to lift the pinning of all guest memory.
Especially with virtio devices implemented in software.
The next step would be to generalize the code in vdpa-sim to allow the
implementation of in-kernel software devices. Similar to vhost, but using vDPA
