Firmware KMS uses a mixture of VC4 processing and dedicated code. The load tracking support in VC4 assumes it is dealing with vc4_plane_state objects when up-casting with container_of, but FKMS uses unadorned drm_plane_state structures causing the VC4 code to read off the end into random portions of memory. Work around the problem in a minimally- invasive way by over-allocating the FKMS plane state structures to be large enough to contain a vc4_plane_state, filling the remainder with zeroes.

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.
