Jason Ekstrand 8579d37eff drm/i915/gt: Drop i915_address_space::file (v2)
There's a big comment saying how useful it is but no one is using this
for anything anymore.

It was added in 2bfa996e03 ("drm/i915: Store owning file on the
i915_address_space") and used for debugfs at the time as well as telling
the difference between the global GTT and a PPGTT.  In f6e8aa3871
("drm/i915: Report the number of closed vma held by each context in
debugfs") we removed one use of it by switching to a context walk and
comparing with the VM in the context.  Finally, VM stats for debugfs
were entirely nuked in db80a1294c ("drm/i915/gem: Remove per-client
stats from debugfs/i915_gem_objects")

v2 (Daniel Vetter):
 - Delete a struct drm_i915_file_private pre-declaration
 - Add a comment to the commit message about history

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.
