Stefano Garzarella 410f36b255 vdpa_sim: fix vringh initialization in vdpasim_queue_ready()
[ Upstream commit 794ec498c9 ]

When we initialize vringh, we should pass the features and the
number of elements in the virtqueue negotiated with the driver,
otherwise operations with vringh may fail.

This was discovered in a case where the driver sets a number of
elements in the virtqueue different from the value returned by
.get_vq_num_max().

In vdpasim_vq_reset() is safe to initialize the vringh with
default values, since the virtqueue will not be used until
vdpasim_queue_ready() is called again.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
