Pull swiotlb updates from Konrad Rzeszutek Wilk:
- minor fixes (rate limiting), remove certain functions
- support for DMA_ATTR_SKIP_CPU_SYNC which is an optimization
in the DMA API
* 'stable/for-linus-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb:
swiotlb: Minor fix-ups for DMA_ATTR_SKIP_CPU_SYNC support
swiotlb: Add support for DMA_ATTR_SKIP_CPU_SYNC
swiotlb-xen: Enforce return of DMA_ERROR_CODE in mapping function
swiotlb: Drop unused functions swiotlb_map_sg and swiotlb_unmap_sg
swiotlb: Rate-limit printing when running out of SW-IOMMU space
