Just drive-by, but we have gsoc running so better to update it now.

Great news is that two entries can be removed because essentially all
done.

 With the recent ``drm_bus`` cleanup patches for 3.17 it is no longer required

-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:
-
-* Make sure legacy IOCTLs can't be used on modern drivers.
-* 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.
-* Extract legacy functions into their own headers and remove it that from the
-  monolithic ``drmP.h`` header.
-* Remove any lingering cruft from the OS abstraction layer from modern
-  drivers.
-
-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.

-Better kerneldoc
-----------------
-
-This is pretty much done, but there's some advanced topics:
-
-Come up with a way to hyperlink to struct members. Currently you can hyperlink
-to the struct using ``#struct_name``, but not to a member within. Would need
-buy-in from kerneldoc maintainers, and the big question is how to make it work
-without totally unsightly
-``drm_foo_bar_really_long_structure->even_longer_memeber`` all over the text
-which breaks text flow.
-
-Figure out how to integrate the asciidoc support for ascii-diagrams. We have a
-few of those (e.g. to describe mode timings), and asciidoc supports converting
-some ascii-art dialect into pngs. Would be really pretty to make that work.
