Perhaps the best way to fix these is to change code like

		if (/* ScoreBoardDrainInProg */
		    test_bit(63, &hwstatus) ||
		    /* AbortInProg */
		    test_bit(62, &hwstatus) ||
		    /* InternalSDmaEnable */
		    test_bit(61, &hwstatus) ||
		    /* ScbEmpty */
		    !test_bit(30, &hwstatus)) {

to something like

		if ((hwstatus & (IPATH_SDMA_STATUS_SCORE_BOARD_DRAIN_IN_PROG |
				 IPATH_SDMA_STATUS_ABORT_IN_PROG	     |
				 IPATH_SDMA_STATUS_INTERNAL_SDMA_ENABLE)) ||
		    !(hwstatus & IPATH_SDMA_STATUS_SCB_EMPTY)) {

with appropriate defines for the constants 1ull << 63 etc.

(I think I got the logic correct but someone should check)

I have a fix for this pending; will ask Linus to pull today.
