Hi, The files drivers/gpu/drm/nouveau/nv50_fbcon.c drivers/gpu/drm/nouveau/nvc0_fbcon.c drivers/video/fbdev/nvidia/nv_accel.c all contain a right-shift of ~0 (aka -1) - just grep for '~0 >>'. gcc always does arithmetic right shift of signed types, which means that the result is always -1 again [type promotion/conversion doesn't kick in until after the shift subexpression has been evaluated], independent of the second operand. I can hardly believe that is intended (the result is used as a mask, which thus consists of all 1s). If these are indeed bugs, the patch is obvious (just make the literal an unsigned 0).
