f2b04cd219 drm/radeon: upgrade to 1.27 - make PCI GART more flexible
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.

80b2c386f3 drm/radeon: Fix u32 overflows when determining AGP base address in card space.
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.

See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=392915 .

b9b603dd1c drm: radeon: Use RADEON_RB3D_DSTCACHE_CTLSTAT instead of RADEON_RB2D_DSTCACHE_CTLSTAT.
The latter seems to be a read-only mirror of the former.

ae1b1a4816 drm: radeon: fix up bus mastering when writeback is disabled
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.

f3dd5c3738 drm: add new radeon PCI ids..
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.

d5ea702f1e drm: rework radeon memory map (radeon 1.23)
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.

22eae947bf drm: rename driver hooks more understandably
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'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

d1f2b55ad2 drm: updated DRM map patch for 32/64 bit systems
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.

1da177e4c3 Linux-2.6.12-rc2
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!
