John Harrison 429915acae drm/xe: Add a reason string to the devcoredump
There are debug level prints giving more information about the cause
of the hang immediately before core dumps are created. However, not
everyone has debug level prints enabled or saves the dmesg log at all.
So include that information in the dump file itself. Also, at least
one of those prints included the pid as well as the process name. So
include that in the capture too.

v2: Fix kvfree vs kfree and missing kernel-doc (review feedback from
Matthew Brost)
v3: Use GFP_ATOMIC instead of GFP_KERNEL.

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.
