c153f45f9b drm: Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.
The data is now in kernel space, copied in/out as appropriate according to t
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures.  This also means that XFree86 4.2.0 support for i810 DR
is lost.

6c340eac02 drm: Replace filp in ioctl arguments with drm_file *file_priv.
As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM.  There is a 1:1 mapping, so this
should be a noop.  This could be a minor performance improvement, as everyth
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioct
went the other direction.

20caafa6ec drm: Remove DRM_ERR OS macro.
This was used to make all ioctl handlers return -errno on linux and errno on
*BSD.  Instead, just return -errno in shared code, and flip sign on return f
shared code to *BSD code.

b5e89ed53e drm: lindent the drm directory.
I've been threatening this for a while, so no point hanging around.
This lindents the DRM code which was always really bad in tabbing department.
I've also fixed some misnamed files in comments and removed some trailing
whitespace.

6795c985a6 Add support for PCI MGA cards to MGA DRM.
This patch adds serveral new ioctls and a new query to get_param query to
support PCI MGA cards.

Two ioctls were added to implement interrupt based waiting.  With this change,
the client-side driver no longer needs to map the primary DMA region or the
MMIO region.  Previously, end-of-frame waiting was done by busy waiting in the
client-side driver until one of the MMIO registers (the current DMA pointer)
matched a pointer to the end of primary DMA space.  By using interrupts, the
busy waiting and the extra mappings are removed.

A third ioctl was added to bootstrap DMA.  This ioctl, which is used by the
X-server, moves a *LOT* of code from the X-server into the kernel.  This allows
the kernel to do whatever needs to be done to setup DMA buffers.  The entire
process and the locations of the buffers are hidden from user-mode.

Additionally, a get_param query was added to differentiate between G4x0 cards
and G550 cards.  A gap was left in the numbering sequence so that, if needed,
G450 cards could be distinguished from G400 cards.  According to Ville
Syrjälä, the G4x0 cards and the G550 cards handle anisotropic filtering
differently.  This seems the most compatible way to let the client-side driver
know which card it's own.  Doing this very small change now eliminates the
need to bump the DRM minor version twice.

(airlied - this may not work at this point, I think the follow on buffer
 cleanup patches will be needed)

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
