mainlining shenanigans
1d0c09dee9
Although GSI is integral to IPA, it is a separate hardware component and the IPA code supporting it has been structured to avoid explicit dependence on IPA details. An example of this is that gsi_init() is passed a number of Boolean flags to indicate special behaviors, whose values are dependent on the IPA hardware version. Looking ahead, newer hardware versions would require even more such special behaviors. For any given version of IPA hardware (like 3.5.1 or 4.2), the GSI hardware version is fixed (in this case, 1.3 and 2.2, respectively). So the IPA version *implies* the GSI version, and the IPA version can be used as effectively the equivalent of the GSI hardware version. Rather than proliferating new special behavior flags, just provide the IPA version to the GSI layer when it is initialized. The GSI code can then use that directly to determine whether special behaviors are required. The IPA version enumerated type is already isolated to its own header file, so the exposure of this IPA detail is very limited. For now, just change gsi_init() to pass the version rather than the Boolean flags, and set the flag values internal to that function.

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.
