drm vblank initialization keeps track of the changes in driver-supplied
frame counts across vt switch and mode setting, but only if you let it by
not tearing down the drm vblank structure.

Previously, drivers supporting vblank interrupt waits would run the interrupt
all the time, or all the time that any 3d client was running, preventing the
CPU from sleeping for long when the system was otherwise idle. Now, interrupts
are disabled any time that no client is waiting on a vblank event. The new
method uses vblank counters on the chipsets when the interrupts are turned
off, rather than counting interrupts, so that we can continue to present
accurate vblank numbers.

With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.
This restructures the drm along the lines of other kernel components.
It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.

This re-works the DRM internals to provide a better interface for drivers
to expose vblank on multiple crtcs.
It also includes work done by Michel on making i915 triple buffering and pageflipping work properly.

As DRM_DEBUG macro already prints out the __FUNCTION__ string (see
drivers/char/drm/drmP.h), it is not worth doing this again. At some
other places the ending "\n" was added.

* Convert files to UTF-8.
* Also correct some people's names
(one example is Eißfeldt, which was found in a source file.
Given that the author used an ß at all in a source file
indicates that the real name has in fact a 'ß' and not an 'ss',
which is commonly used as a substitute for 'ß' when limited to
7bit.)
* Correct town names (Goettingen -> Göttingen)

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

radeon: make PCI GART aperture size variable, but making table size variable
This is precursor to getting a TTM backend for this stuff, and also
allows the PCI table to be allocated at fb 0
radeon: add support for reverse engineered xpress200m
The IGPGART setup code was traced using mmio-trace on fglrx by myself
and Phillip Ezolt <phillipezolt@gmail.com> on dri-devel.
This code doesn't let the 3D driver work properly as the card has no
vertex shader support.
Thanks to Matthew Garrett + Ubuntu for providing me some hardware to do this
work on.

Rename the driver hooks in the DRM to something a little more understandable:
preinit -> load
postinit -> (removed)
presetup -> firstopen
postsetup -> (removed)
open_helper -> open
prerelease -> preclose
free_filp_priv -> postclose
pretakedown -> lastclose
postcleanup -> unload
release -> reclaim_buffers_locked
version -> (removed)
postinit and version were replaced with generic code in the Linux DRM (drivers
now set their version numbers and description in the driver structure, like on
BSD). postsetup wasn't used at all. Fixes the savage hooks for
initializing and tearing down mappings at the right times. Testing involved at
least starting X, running glxgears, killing glxgears, exiting X, and repeating.
Tested on: FreeBSD (g200, g400, r200, r128)

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

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!
