2010-04-28drm/radeon/kms/agp The wrong AGP chipset can cause a NULL pointer dereferenceRobert Fitzsimons
Selecting the wrong or no CONFIG_AGP_* chipset can cause a NULL pointer dereference when combined with CONFIG_DRM_RADEON_KMS and an old system with a R100 AGP card (should effect other cards too). The agp field will be set to NULL if no suitable AGP chipset driver is loaded, drm_agp_acquire already preforms a suitable NULL check so it can be used directly.

2010-04-27drm/radeon: Fix sparc regression in r300_scratch()David Miller
Commit b4fe945405e477cded91772b4fec854705443dd5 ("drm/radeon: Fix memory allocation failures in the preKMS command stream checking.") added a regression in that it completely tossed the get_unaligned() done by r300_scratch() which we added in commit 958a6f8ccb1964adc3eec84cf401c5baeb4fbca0 ("drm: radeon: Fix unaligned access in r300_scratch().").

2010-04-27drm: make sure vblank interrupts are disabled at DPMS timeJesse Barnes
When we call drm_vblank_off() at DPMS off time (to wake any clients so they don't hang) we need to make sure interrupts are actually disabled. If drm_vblank_off() gets called before the vblank usage timer expires, it'll prevent the timer from disabling interrupts since it also clears the vblank_enabled flag for the pipe.

All indications seem to be that the version 0x30 table should be handled the same way as 0x40 (as used on G80), at least for the parts that we currently try use.
