Matt Roper f5508f1e65 drm/xe: Adjust mmio code to pass VF substructure to SRIOV code 
[ Upstream commit 6fb5d1a1d3 ]

Although we want to break the GT-centric nature of the MMIO code in the
general driver, the SRIOV handling still relies on data in a VF
substructure of the GT.  So add a GT backpointer, but name it
sriov_vf_gt to make it clear that it's only for this one specific
special case and will not be set or usable for anything else.

v2:
 - Store backpointer to the GT itself rather than the SRIOV-specific
   substructure.  (Michal)

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.
