From 204f3a04449a9a775e465f7d87bcab08f170e59e Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Wed, 26 May 2010 14:44:30 -0700 Subject: asm-generic: remove ISA_DMA_THRESHOLD in scatterlist.h This is the first half of the attempt to use asm-generic/scatterlist.h on every architecture. There are only two ways to define scatterlist structure. So it's easy to convert every architecture to use asm-generic/scatterlist.h. This patch: 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.
