Let's replace the assortment of intel_gt_* and intel_uncore_* functions
that operate on MCR registers with a cleaner set of interfaces:

  * intel_gt_mcr_read -- unicast read from specific instance
  * intel_gt_mcr_read_any[_fw] -- unicast read from any non-terminated
    instance
  * intel_gt_mcr_unicast_write -- unicast write to specific instance
  * intel_gt_mcr_multicast_write[_fw] -- multicast write to all instances

We'll also replace the historic "slice" and "subslice" terminology with
"group" and "instance" to match the documentation for more recent
platforms; these days MCR steering applies to more types of replication
than just slice/subslice.

v2:
 - Reference the new kerneldoc from i915.rst.  (Jani)
 - Tweak the wording of the documentation for a couple functions to
   clarify the difference between "_fw" and non-"_fw" forms.

v3:
 - s/read/write/ to fix copy-paste mistake in a couple comments.

History
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.
