GLK has always been a bit of a special case since it reports INTEL_GEN()
as 9, but has version 10 display IP. Now we can properly represent the
display version as 10 and simplify the display generation tests
throughout the display code.
Aside from manually adding the version to the glk_info structure, the
rest of this patch is generated with a Coccinelle semantic patch. Note
that we also need to switch any code that matches gen10 today but *not*
GLK to be CNL-specific:

v2:
- Convert gen10 conditions that don't include GLK into CNL conditions.
(Ville)
v3:
- Rework coccinelle rules so that "ver>=10" turns into "ver>=11||is_cnl." (Ville)
v3.1:
- Manually re-add the ".display.version = 10" to glk_info after
regenerating patch via Coccinelle.
v4:
- Also apply cocci rules to intel_pm.c and i915_irq.c! (CI)

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.
