drm: rip out DRM_AGP_MEM and DRM_AGP_KERN

2013-12-18T01:32:55Z

The header provides dummy functions and fallbacks, so no need for screaming macros. Signed-off-by: Daniel Vetter Signed-off-by: Dave Airlie

drm: inline drm_agp_destroy

2013-12-18T01:23:46Z

Wrapping a kfree is pointless. v2: Add a comment to the kerneldoc for drm_agp_init to explain where the kfree happens as requested by David. Note that for modeset drivers agp cleanup is fairly complicated anyway: The drm_agp_clear is a noop and drivers must call drm_agp_release on their own. Which they all seem to do properly.

drm: rip out drm_core_has_AGP

2013-12-18T01:20:04Z

Most place actually want to just check for dev->agp (most do, but a few don't so this fixes a few potential NULL derefs). The only exception is the agp init code which should check for the AGP driver feature flag. Signed-off-by: Daniel Vetter Signed-off-by: Dave Airlie

drm: provide agp dummies for CONFIG_AGP=n

2013-08-08T21:22:11Z

We currently rely on gcc dead-code elimination so the drm_agp_* helpers are not called if drm_core_has_AGP() is false. That's ugly as hell so provide "static inline" dummies for the case that AGP is disabled.
