Chris Wilson 3dc007fe9b drm/i915/gtt: Downgrade gen7 (ivb, byt, hsw) back to aliasing-ppgtt
With the upcoming change in timing (dramatically reducing the latency
between manipulating the ppGTT and execution), no amount of tweaking
could save Baytrail, it would always fail to invalidate its TLB. Ville
was right, Baytrail is beyond hope.

v2: Rollback on all gen7; same timing instability on TLB invalidation.

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.
