swiotlb: do not export map_single function
The map_single() function is not defined as static, even though it doesn't seem to be used anywhere else in the kernel. Make it static to avoid namespace pollution since this is a rather generic symbol. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
