Subject: [PATCH 0/3] dma-mapping:remove CONFIG_HAVE_DMA_ATTRS
Date: Sat, 4 Jul 2009 10:34:52 +0800 [thread overview]
Message-ID: <1246674895-9610-1-git-send-email-tom.leiming@gmail.com> (raw)
This patch sets enable CONFIG_HAVE_DMA_ATTRS always, so remove
it in dma-mapping and Kconfig of X86 and IA64 arch, based on
the following ideas:
1,Currently asm-generic/dma-mapping-common.h has provided dma_map_*_attrs()
and dma_unmap_*_attrs(), and more ARCHs will move to asm-generic/dma-mapping-common.h;
2,Disabling CONFIG_HAVE_DMA_ATTRS may lead to a compile failure;
3,X86 and IA64 has taken asm-generic/dma-mapping-common.h and always enabled the
option now;
4,If CONFIG_HAVE_DMA_ATTRS is enabled, dma_set/get_attr support the passed attrs
is NULL.
