Matthew Auld fb87550d25 drm/i915/selftests: exercise mmap migration
Exercise each of the migration scenarios, verifying that the final
placement and buffer contents match our expectations.

v2(Thomas): Replace for_i915_gem_ww() block with simpler object_lock()

v3:
- For testing purposes allow forcing the io_size such that we can
  exercise the allocation + migration path on devices that don't have the
  small BAR limit.

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.
