Just as an FYI, this introduces a warning on arm32 allyesconfig for me:
I think the dma_limit argument to iommu_dma_alloc_iova should be a u64 and/or we need to use min_t and open code the zero exception. Robin, Nicolas - any opinions? Also I wonder how this file gets compiled on arm32 given that arm32 has its own set of iommu dma ops..
