From: FUJITA Tomonori Date: Thu, 17 Jun 2010 15:56:05 +0000 (-0700) Subject: bnx2: fix dma_get_ops compilation breakage X-Git-Tag: v2.6.35-rc4~54^2~23 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aabef8b240880439b91574c9a9e33dcc44bfd8c7;p=pandora-kernel.git bnx2: fix dma_get_ops compilation breakage This removes dma_get_ops() prefetch optimization in bnx2. bnx2 uses dma_get_ops() to see if dma_sync_single_for_cpu() is noop. bnx2 does prefetch if it's noop. But dma_get_ops() isn't available on all the architectures (only the architectures that uses dma_map_ops struct have it). Using dma_get_ops() in drivers leads to compilation breakage on many architectures. This patch removes dma_get_ops() and changes bnx2 to do prefetch on all the architectures. This adds useless prefetch on non-coherent architectures but this is harmless. It is also unlikely to cause the performance drop.
