Mark Nelson 1ed6af7344 powerpc/cell: Add DMA_ATTR_WEAK_ORDERING dma attribute and use in Cell IOMMU code ... Introduce a new dma attriblue DMA_ATTR_WEAK_ORDERING to use weak ordering on DMA mappings in the Cell processor. Add the code to the Cell's IOMMU implementation to use this code. Dynamic mappings can be weakly or strongly ordered on an individual basis but the fixed mapping has to be either completely strong or completely weak. This is currently decided by a kernel boot option (pass iommu_fixed=weak for a weakly ordered fixed linear mapping, strongly ordered is the default).
