Subject[bk pull] DRM tree for 2.6.12 - fixes

Hi Linus,
The latest DRM bitkeeper tree with any patches necessary for
2.6.12 is available.
This fixes 2 big bugs introduced since 2.6.11 - one in AGP bridge
handling and the other for XFree86 4.3 users.. it also has an updated
radeon driver and some minor cleanups/fixes..

Please do a

bk pull bk://drm.bkbits.net/drm-linus

This will include the latest DRM changes and will update the following files:

drivers/char/agp/backend.c | 1 +
drivers/char/drm/drm_agpsupport.c | 15 ++++++++++-----

agp: export agp_find_bridge for drm

Signed-off-by: Dave Airlie <airlied@linux.ie>

<airlied@starflyer.(none)> (05/03/24 1.2199.17.3)
drm: fix issue where agp is acquired before agp_init

With integrated chipsets ala i865 the X server acquires the bridge
for 2D operations then the DRM acquires it for 3D kaboom..

Based on patch from Brice Goglin <Brice.Goglin@ens-lyon.org> but I
think this patch is safer if it can't find a bridge it acquires it.

Tested on i865 (i830/i915) and Radeon on Xorg CVS and XFree86 4.3.0

drm: issue with unique for XFree86 4.3 backwards compatibility

This got broken at some stage not sure when exactly... but it caused
XFree86 4.3 issues and I had to install sarge...

<airlied@starflyer.(none)> (05/03/24 1.2199.17.1)
verify_area is deprecated, replaced by access_ok.
Seems I missed this one when I did the big overall conversion.
