From 441921d5309cfe098747d9840fd71bdc6ca2a93b Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 18 Feb 2011 17:59:16 +0100 Subject: [PATCH] drm/radeon: embed struct drm_gem_object Unconditionally initialize the drm gem object - it's not worth the trouble not to for the few kernel objects. This patch only changes the place of the drm gem object, access is still done via pointers. v2: Uncoditionally align the size in radeon_bo_create. At least the r600/evergreen blit code didn't to this, angering the paranoid gem code.
