[PATCH] drm/ttm: fix ttm tt init fail when size exceeds kmalloc limit

if the __GFP_ZERO is set, the kvmalloc() can't fallback to use vmalloc() to allocate memory, when request size is exceeds kmalloc limit, it will cause allocate memory fail. e.g: when ttm want to create a BO with 1TB size, it maybe fail. Signed-off-by: Yang Wang --- drivers/gpu/drm/ttm/ttm
