    Subject[PATCH 08/10] xen/swiotlb: Remove functions not needed anymore.
    Date
    Sparse warns us off:
    drivers/xen/swiotlb-xen.c:506:1: warning: symbol 'xen_swiotlb_map_sg' was not declared. Should it be static?
    drivers/xen/swiotlb-xen.c:534:1: warning: symbol 'xen_swiotlb_unmap_sg' was not declared. Should it be static?

    and it looks like we do not need this function at all.
