Adapt core x86 and IA64 architecture code for dma_map_ops changes: replace alloc/free_coherent with generic alloc/free methods. Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Acked-by: Kyungmin Park <kyungmin.park@samsung.com> [removed swiotlb related changes and replaced it with wrappers, merged with IA64 patch to avoid inter-patch dependences in intel-iommu code] Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Tony Luck <tony.luck@intel.com>
