thorpej e2a2842013 Keep track of which DMA window was actually used to map the ... request (not always the passed in DMA tag if we try direct-map and then fall back to sgmap-mapped). Use the actual window when performing dmamap_sync and dmamap_unload operations. Fixes DMA resource leak on systems with 2G+ RAM. Thanks to Matt Thomas for help debugging this.		2002-04-26 04:15:18 +00:00
