From 60d8cd572f655aac6107a2330dced004ad1fe3d7 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 16 Jan 2019 19:01:48 +0100 Subject: arm64/xen: fix xen-swiotlb cache flushing Xen-swiotlb hooks into the arm/arm64 arch code through a copy of the DMA DMA mapping operations stored in the struct device arch data. Switching arm64 to use the direct calls for the merged DMA direct / swiotlb code broke this scheme. Replace the indirect calls with direct-calls in xen-swiotlb as well to fix this problem. Fixes: 356da6d0cde3 ("dma-mapping: bypass indirect calls for dma-direct") Reported-by: Julien Grall Signed-off-by: Christoph Hellwig Reviewed-by: Stefano Stabellini --- arch/arm64/include/asm/device.h | 3 --- 1 file changed, 3 deletions(-) (limited to 'arch/arm64/include/asm/device.h') diff --git a/arch/arm64/include/asm/device.h b/arch/arm64/include/asm/device.h index 3dd3d664c5c5..4658c937e173 100644 --- a/arch/arm64/include/asm/device.h +++ b/arch/arm64/include/asm/device.h @@ -20,9 +20,6 @@ struct dev_archdata { #ifdef CONFIG_IOMMU_API void *iommu; /* private IOMMU data */ #endif -#ifdef CONFIG_XEN - const struct dma_map_ops *dev_dma_ops; -#endif }; struct pdev_archdata { -- cgit v1.2.3
