Daniel complained that we keep adding stuff to the bottom of the file, so we constantly have conflicts. So reorganize everything and split them file-by-file, also sorting the files in alphabetical order. This way, patches touching different files will have a smaller chance of conflicting. Of course, this commit will conflict with everybody on the list :) Also remove a few useless comments and make some things fit into 80 lines. v2: - Conflict with intel_ddi_get_config Requested-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).
The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:
1. The DRM provides synchronized access to the graphics hardware via
the use of an optimized two-tiered lock.
2. The DRM enforces the DRI security policy for access to the graphics
hardware by only allowing authenticated X11 clients access to
restricted regions of memory.
3. The DRM provides a generic DMA engine, complete with multiple
queues and the ability to detect the need for an OpenGL context
switch.
4. The DRM is extensible via the use of small device-specific modules
that rely extensively on the API exported by the DRM module.
Documentation on the DRI is available from:
