WaEnableStateCacheRedirectToCS context workaround configures the L3 cache to benefit 3d workloads but media has different requirements. Remove the workaround and whitelist the register to allow any userspace configure the behaviour to their liking. v2: * Remove the workaround apart from adding the whitelist.

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.
