Now that we record the default "goldenstate" context, we do not need to emit the mocs registers at the start of each context and can simply do mmio before the first context and capture the registers as part of its default image. As a consequence, this means that we repeat the mmio after each engine reset, fixing up any platform and registers that were zapped by the reset (for those platforms with global not context-saved settings).

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.
