Add support for the drm_panic module, which displays a message to the screen when a kernel panic occurs. v7 * Use drm_for_each_primary_visible_plane() v8: * Replace get_scanout_buffer() logic with drm_panic_set_buffer() (Thomas Zimmermann) v9: * Revert to using get_scanout_buffer() (Sima) * move get_scanout_buffer() to plane helper functions v12: * Use array for map and pitch in struct drm_scanout_buffer to support multi-planar format later.

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 reStructuredText 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.
