mainlining shenanigans
ce2fce2513
Several of our i915 header files, have been including i915_reg.h. This means that any change to i915_reg.h will trigger a full rebuild of pretty much every file of the driver, even those that don't have any kind of register access. Let's delete the i915_reg.h include from all headers and add an explicit include from the .c files that truly need the register definitions; those that need a definition of i915_reg_t for a function definition can get it from i915_reg_defs.h instead. We also remove two non-register #define's (VLV_DISPLAY_BASE and GEN12_SFC_DONE_MAX) into i915_reg_defs.h to allow us to drop the i915_reg.h include from a couple of headers. There's probably a lot more header dependency optimization possible, but the changes here roughly cut the number of files compiled after 'touch i915_reg.h' in half --- a good first step.

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.
