Christoph Hellwig 4a54d16f61 dma-mapping: truncate dma masks to what dma_addr_t can hold ... The dma masks in struct device are always 64-bits wide. But for builds using a 32-bit dma_addr_t we need to ensure we don't store an unsupportable value. Before Linux 5.0 this was handled at least by the ARM dma mapping code by never allowing to set a larger dma_mask, but these days we allow the driver to just set the largest supported value and never fall back to a smaller one. Ensure this always works by truncating the value. Fixes: 9eb9e96e97 ("Documentation/DMA-API-HOWTO: update dma_mask sections") Signed-off-by: Christoph Hellwig <hch@lst.de>		2019-06-25 07:54:06 +02:00
