Instead of a quick hack to fix this, we should defer until we have the real solution in place (allocating much less contiguous space). This wasn't found sooner because we didn't not have any systems supporting more than a 2GB GTT. Signed-off-by: Ben Widawsky Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
