Vivek Kasireddy 06a0f77195 drm/virtio: Implement VIRTIO_GPU_CMD_RESOURCE_DETACH_BACKING cmd
This cmd is useful to let the VMM (i.e, Qemu) know that the backing
store associated with a resource is no longer valid, so that the VMM
can perform any cleanup or unmap operations.

The fence related changes and virtio_gpu_object_detach()/
virtio_gpu_detach_object_fenced() routines are extracted from a
patch by Dmitry Osipenko <dmitry.osipenko@collabora.com>.

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 reStructuredText 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.
