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?

Yeah, given that it's always held a mask I'm not entirely sure why it 
was ever a dma_addr_t rather than a u64. Unless anyone else is desperate 
to do it I'll get a cleanup patch ready for rc1.

Sounds good to me too

Robin, since I started the mess, I'll be happy to do it if it helps offloading
some work from you.

Nicolas
