[PATCH] swiotlb: support syncing sub-ranges of mappings
This patch implements swiotlb_sync_single_range_for_{cpu,device}. This is intended to support an x86_64 implementation of dma_sync_single_range_for_{cpu,device}. Signed-off-by: John W. Linville <linville@tuxdriver.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
