From 8d396ded71a9b378fc3e846095e50565606f2df6 Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Tue, 25 Mar 2008 18:36:31 -0300 Subject: [PATCH] x86: move alloc and free coherent to common header they are the same between architectures. (except for the fact that x86_64 has duplicate code) move them to dma-mapping.h Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner --- include/asm-x86/dma-mapping.h | 10 ++++++++++ include/asm-x86/dma-mapping_32.h | 9 --------- include/asm-x86/dma-mapping_64.h | 11 ----------- 3 files changed, 10 insertions(+), 20 deletions(-) diff --git a/include/asm-x86/dma-mapping.h b/include/asm-x86/dma-mapping.h index 53a404b0f9..3ea3802ff1 100644 --- a/include/asm-x86/dma-mapping.h +++ b/include/asm-x86/dma-mapping.h @@ -52,6 +52,16 @@ struct dma_mapping_ops { extern const struct dma_mapping_ops *dma_ops; +#define dma_alloc_noncoherent(d, s, h, f) dma_alloc_coherent(d, s, h, f) +#define dma_free_noncoherent(d, s, v, h) dma_free_coherent(d, s, v, h) + +void *dma_alloc_coherent(struct device *dev, size_t size, + dma_addr_t *dma_handle, gfp_t flag); + +void dma_free_coherent(struct device *dev, size_t size, + void *vaddr, dma_addr_t dma_handle); + + #ifdef CONFIG_X86_32 # include "dma-mapping_32.h" #else diff --git a/include/asm-x86/dma-mapping_32.h b/include/asm-x86/dma-mapping_32.h index eff42f4951..d8f6420d3e 100644 --- a/include/asm-x86/dma-mapping_32.h +++ b/include/asm-x86/dma-mapping_32.h @@ -8,15 +8,6 @@ #include #include -#define dma_alloc_noncoherent(d, s, h, f) dma_alloc_coherent(d, s, h, f) -#define dma_free_noncoherent(d, s, v, h) dma_free_coherent(d, s, v, h) - -void *dma_alloc_coherent(struct device *dev, size_t size, - dma_addr_t *dma_handle, gfp_t flag); - -void dma_free_coherent(struct device *dev, size_t size, - void *vaddr, dma_addr_t dma_handle); - static inline dma_addr_t dma_map_page(struct device *dev, struct page *page, unsigned long offset, size_t size, enum dma_data_direction direction) diff --git a/include/asm-x86/dma-mapping_64.h b/include/asm-x86/dma-mapping_64.h index 707dbbe86a..ce881d9922 100644 --- a/include/asm-x86/dma-mapping_64.h +++ b/include/asm-x86/dma-mapping_64.h @@ -12,17 +12,6 @@ static inline int dma_mapping_error(dma_addr_t dma_addr) return (dma_addr == bad_dma_address); } -#define dma_alloc_noncoherent(d, s, h, f) dma_alloc_coherent(d, s, h, f) -#define dma_free_noncoherent(d, s, v, h) dma_free_coherent(d, s, v, h) - -#define dma_alloc_noncoherent(d, s, h, f) dma_alloc_coherent(d, s, h, f) -#define dma_free_noncoherent(d, s, v, h) dma_free_coherent(d, s, v, h) - -extern void *dma_alloc_coherent(struct device *dev, size_t size, - dma_addr_t *dma_handle, gfp_t gfp); -extern void dma_free_coherent(struct device *dev, size_t size, void *vaddr, - dma_addr_t dma_handle); - #define dma_map_page(dev,page,offset,size,dir) \ dma_map_single((dev), page_address(page)+(offset), (size), (dir)) -- 2.39.5
