Andrzej Hajda 3659e33c1e drm/i915: fix TLB invalidation for Gen12 video and compute engines
commit 04aa64375f48a5d430b5550d9271f8428883e550 upstream.

In case of Gen12 video and compute engines, TLB_INV registers are masked -
to modify one bit, corresponding bit in upper half of the register must
be enabled, otherwise nothing happens.

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.

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.
