Changes this round: - Rebased onto linux-next - IOVA alignment fix applied already - iommu_iova_cache_init() is now iova_cache_get() - Tidied up iommu_dma_alloc() - Simplified pgprot handling - Removed redundant memset - Skip coherent page-flushing in a simpler way - Spotted a bug in iommu_dma_init_domain() where the checks for reinitialising an existing domain were backwards. If it is going to be down to me to tackle all the driver fixes and conversion of arch/arm dma_ops, I'd still much rather have this code merged first as a stable base to work with (and un-block arm64 in the meantime). Have we decided yet whether this should go via the IOMMU tree or the arm64 tree? Thanks, Robin.
