intel-iommu: Introduce domain_sg_mapping() to speed up intel_map_sg() Instead of calling domain_pfn_mapping() repeatedly with single or small numbers of pages, just pass the sglist in. It can optimise the number of cache flushes like domain_pfn_mapping() does, and gives a huge speedup for large scatterlists. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
