Gerd Hoffmann 9286766ba6 drm/vram: add vram-mm debugfs file
Wire up drm_mm_print() for vram helpers, using a new
debugfs file, so one can see how vram is used:

   # cat /sys/kernel/debug/dri/0/vram-mm

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.
