And I still don't think this is the issue.

Your patch removes two lines from drivers/staging/gma500/psb_drm.h with
the following diff:
--- a/drivers/staging/gma500/psb_drm.h
+++ b/drivers/staging/gma500/psb_drm.h
@@ -28,9 +28,6 @@
 #include "drm_mode.h"
 #endif
 
-#include "psb_ttm_fence_user.h"
-#include "psb_ttm_placement_user.h"
-
 #define DRM_PSB_SAREA_MAJOR 0
 #define DRM_PSB_SAREA_MINOR 2
 #define PSB_FIXED_SHIFT 16


Yet those #defines are not present in this file right now.  That's not a
whitespace change...

Still confused,
