mainlining shenanigans
795f672b88
On ivb+ we can select between the regular 10bit LUT mode with 1024 entries, and the split mode where the LUT is split into seprate degamma and gamma halves (each with 512 entries). Currently we expose the split gamma size of 512 as the GAMMA/DEGAMMA_LUT_SIZE. When using only degamma or gamma (not both) we are wasting half of the hardware LUT entries. Let's flip that around so that we expose the full 1024 entries and just throw away half of the user provided entries when using the split gamma mode.

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.
