This code relied on the CPU and GPU address for the aperture being the same,
On some r5xx hardware I was playing with I noticed that this isn't always true.
This fixes issues seen on some r400 cards. (bugs.freedesktop.org 9957)

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

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

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.

The overflows could lead to the AGP aperture overlapping the framebuffer are in the card's address space when the latter is located at the very end of th 32 bit address space, which would result in a freeze on X server startup,
probably because the card read commands from the framebuffer instead of from AGP.

When writeback isn't used, actually disable it in the hardware.
Not doing this might waste bus bandwidth or even cause memory corruption or
system crashes on systems that check bus transfers. No such incident has been
reported though.

This adds all the r300 and r400 PCI ids from DRM CVS, it also
makes these cards only initialise when the new xorg driver is
used, as otherwise the DRM can cause lockups.

This code reworks the radeon memory map so it works better
for newer r300 chips and for a lot of older PCI chips.
It really requires a new X driver in order to take advantage of this code.

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)
Linux (r200, savage4)

I basically combined Paul's patches with additions that I had made
for PCI scatter gather.
I also tried more carefully to avoid problems with the same token
assigned multiple times while trying to use the base address in the
token if possible to gain as much backward compatibility as possible
for broken DRI clients.

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!
