As the aliasing GTT is only accessed via the global GTT, we will never use more of it than we expose via the Global GTT and so we only need to preallocate sufficient space within the ppgtt for the full GTT. Equally, if the aliasing GTT is smaller than the global GTT, we have a serious issue and must bail. Signed-off-by:
