Hi Rob,
here is a patch series that cleans up all file references for dt-bindings
in MAINTAINERS. It applies cleanly on next-20210315.
With this patch series and another patch (already accepted elsewhere)
[see Link], ./scripts/get_maintainers.pl --self-test=patterns reports no
further warning on
Some references in MAINTAINERS can be automatically rectified with
./scripts/documentation-file-ref-check --fix.
Adjust those file entries with this script.

Kbuild never invokes 'as' directly because all assembly files in the

The identical mapping used until now created issues when mapping
different virtual pages with the same physical address.
To solve this issue, we can use the iova module, to handle the IOVA
allocation.
For simplicity we use an IOVA allocator with byte granularity.
We add two new functions, vdpasim_
__vringh_iov() overwrites the contents of riov and wiov, in fact it
resets the 'i' and 'used' fields, but also the 'consumed' field should
be reset to avoid an inconsistent state.

In some cases, it may be useful to provide a way to skip a number
of bytes in a vringh_kiov.
Let's implement vringh_kiov_advance() for this purpose, reusing the
code from vringh_iov_xfer().
We replace that code calling the new vringh_kiov_advance().

riov and wiov can be reused with subsequent calls of vringh_getdesc_*().
Let's add a paragraph in the documentation of these functions to better
explain when riov and wiov need to be cleaned up.

vringh_getdesc_iotlb() allocates memory to store the kvec, that
is freed with vringh_kiov_cleanup().
vringh_getdesc_iotlb() is able to reuse a kvec previously allocated,
so in order to avoid to allocate the kvec for each request, we are
not calling vringh_kiov_cleanup() when we finished to handle

This will allow running vDPA for virtio block protocol.
It's a preliminary implementation with a simple request handling:
for each request, only the status (last byte) is set.
It's always set to VIRTIO_BLK_S_OK.
Also input validation is missing and will be added in the next c
Let's use the new 'get_config_size()' callback available instead of
using the 'virtio_id' to get the size of the device config space.

Since the config checks are done by the vDPA drivers, we can remove the
virtio-net restriction and we should be able to support all kinds of

The previous implementation wrote only the status of each request.
This patch implements a more accurate block device simulator,
providing a ramdisk-like behavior and adding input validation.
