Chris Wilson 1fc719d13a drm/i915/ringbuffer: Brute force context restore
An issue encountered with switching mm on gen7 is that the GPU likes to
hang (with the VS unit busy) when told to force restore the current
context. We can simply workaround this by substituting the
MI_FORCE_RESTORE flag with a round-trip through the kernel_context,
forcing the context to be saved and restored; thereby reloading the
PP_DIR registers and updating the modified page directory!

v2: Undo attempted optimisation in caller (Tvrtko)

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
