It seems to be in drivers/base/platform.c conditional on ARCH_HAS_DMA_GET_REQUIRED_MASK, but according to my grep no architecture ever sets that flag.

Just nobody seems to have done it so far. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
