Chris Wilson d7cb6975f1 drm/i915/gt: Always force restore freshly pinned contexts
It is highly unlikely, but still conceivable, that we submit a context
with the same GGTT address as last active on the HW. In this case, with
a matching LRCA, the HW would not restore the new context image causing
a potential violation of our context isolation.

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.
