Prev: [PATCH -mm 3/5] powerpc: use asm-generic/scatterlist.h
Next: [PATCH -mm 2/5] asm-generic: add NEED_SG_DMA_LENGTH to define sg_dma_len()
From: FUJITA Tomonori on 4 Apr 2010 10:50 The trick for ISA_DMA_THRESHOLD in asm-generic/scatterlist.h doesn't work for powerpc. This lets architectures defin ISA_DMA_THRESHOLD. Hopefully, we can remove ISA_DMA_THRESHOLD in the future; we can do better to decide if the bouncing is necessary or not.
