[PATCH -mm 2/2] remove dma_is_consistent API
Architectures implement dma_is_consistent() in different ways (some misinterpret the definition of API in DMA-API.txt). So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't ... 22 Jul 2010 08:07

[PATCH] md: bitwise operations might not fit in a "bool"
when taking a resolute of a bit-wise AND as true false. Better / faster to make it a boolean operation. This fixes a bug and a crash because the flags field did not fit into the bool operands.

[PATCH -mm 1/2] 53c700: remove dma_is_consistent usage
This driver is the only user of dma_is_consistent(). We plan to remove this API. The driver uses the API in the following way: BUG_ON(!dma_is_consistent(hostdata->dev, pScript) && L1_CACHE_BYTES < dma_get_cache_alignment()); The above code tries to see if L1_CACHE_BYTES is greater than dma_get_cache_alignmen... 22 Jul 2010 08:07
