From: Greg Ungerer Date: Thu, 29 Jan 2009 05:35:34 +0000 (+1000) Subject: m68k: swtich non-mmu setups to use the mmu dma-mapping.h X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9a4048a211513c3d6c56ddf2efb276113eae0b80;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git m68k: swtich non-mmu setups to use the mmu dma-mapping.h The mmu version of dma-mapping.h (which is dma-mapping_mm.h) is clean to be used for non-mmu setups as well. Remove dma-mapping_no.h and revert dma-mapping_mm.h to dma-mapping.h Signed-off-by: Greg Ungerer Acked-by: Geert Uytterhoeven --- diff --git a/arch/m68k/include/asm/dma-mapping.h b/arch/m68k/include/asm/dma-mapping.h index f4a4c7638f89..26f505488c11 100644 --- a/arch/m68k/include/asm/dma-mapping.h +++ b/arch/m68k/include/asm/dma-mapping.h @@ -1,5 +1,112 @@ -#ifdef __uClinux__ -#include "dma-mapping_no.h" +#ifndef _M68K_DMA_MAPPING_H +#define _M68K_DMA_MAPPING_H + +#include + +struct scatterlist;
