 Clean up the DRM header mess
 ----------------------------
 
-Currently the DRM subsystem has only one global header, ``drmP.h``. This is
-used both for functions exported to helper libraries and drivers and functions
-only used internally in the ``drm.ko`` module. The goal would be to move all
-header declarations not needed outside of ``drm.ko`` into
-``drivers/gpu/drm/drm_*_internal.h`` header files. ``EXPORT_SYMBOL`` also
-needs to be dropped for these functions.
-
-This would nicely tie in with the below task to create kerneldoc after the API
-is cleaned up. Or with the "hide legacy cruft better" task.
-
-Note that this is well in progress, but ``drmP.h`` is still huge. The updated
-plan is to switch to per-file driver API headers, which will also structure
-the kerneldoc better. This should also allow more fine-grained ``#include``
-directives.
+The DRM subsystem originally had only one huge globale header, ``drmP.h``. This
+is not split up, but many source files still include it. The remainig part of
+the cleanup work here is to replace any ``#include <drm/drmP.h>`` by only the
+headers needed (and fixing up any missing pre-declarations in the headers).
 
 In the end no .c file should need to include ``drmP.h`` anymore.

-Hide legacy cruft better
-------------------------
-
-Way back DRM supported only drivers which shadow-attached to PCI devices with
-userspace or fbdev drivers setting up outputs. Modern DRM drivers take charge
-of the entire device, you can spot them with the DRIVER_MODESET flag.
-
-Unfortunately there's still large piles of legacy code around which needs to
-be hidden so that driver writers don't accidentally end up using it. And to
-prevent security issues in those legacy IOCTLs from being exploited on modern
-drivers. This has multiple possible subtasks:
-
-* Extract support code for legacy features into a ``drm-legacy.ko`` kernel
-  module and compile it only when one of the legacy drivers is enabled.
-
-This is mostly done, the only thing left is to split up ``drm_irq.c`` into
-legacy cruft and the parts needed by modern KMS drivers.
