As reported by Andy, kernel-doc.py is creating a __pycache__
directory at build time.
Disable creation of __pycache__ for the libraries used by
kernel-doc.py, when excecuted via the build system or via
scripts/find-unused-docs.sh.

I will send out a patch to replace __copy_from_user() with copy_from_user().

This reverts commit 18d7de823b7150344d242c3677e65d68c5271b04.
This given a misuse of vmap_pfn, vmap_pfn only allow none-page based

Kernel BO's aren't exposed to UM, so labelling them is the responsibility
of the driver itself. This kind of tagging will prove useful in further

Add a device DebugFS file that displays a complete list of all the DRM

Add a new character string Panthor BO field, and a function that allows
setting it from within the driver.
Driver takes care of freeing the string when it's replaced or no longer
needed at object destruction time, but allocating it is the responsibility
of callers.

This patch series is aimed at providing UM with detailed memory profiling
information in debug builds. It is achieved through a device-wide list of
DRM GEM objects, and also implementing the ability to label BO's from UM
through a new IOCTL.
The new debugfs file shows a list of driver DRM GEM obje

Currently userspace software systemd treats `brightness` and
`actual_brightness` identically due to a bug found in an out of tree
driver.
This however causes problems for in-tree drivers that use brightness
