  "message": "USB: remove uses of URB_NO_SETUP_DMA_MAP\n\nThis patch (as1350) removes all usages of coherent buffers for USB\ncontrol-request setup-packet buffers.  There\u0027s no good reason to\nreserve coherent memory for these things; control requests are hardly\never used in large quantity (the major exception is firmware\ntransfers, and they aren\u0027t time-critical).  Furthermore, only seven\ndrivers used it.  We might as well always use streaming DMA mappings\nfor setup-packet buffers, and remove some extra complexity from\nusbcore.\n\nThe DMA-mapping portion of hcd.c is currently in flux.  A separate\npatch will be submitted to remove support for URB_NO_SETUP_DMA_MAP\nafter everything else settles down.  The removal should go smoothly,\nas by then nobody will be using it.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
