From: Santosh Shilimkar <santosh.shilimkar@xxxxxx> The blk_queue_bounce_limit() API parameter 'dma_mask' is actually the maximum address the device can handle rather than a dma_mask. Rename it accordingly to avoid it being interpreted as dma_mask. No functional change. The idea is to fix the bad assumptions about dma_mask wherever it could be miss-interpreted.
