[GIT PULL] iommu/arm-smmu: Fixes for 4.11

[Will Deacon]

Hi Joerg,

Please pull these two ARM io-pgtable fixes from Oleksandr for 4.11. They're
not critical, but they mean that we detect misuses in the iommu_{map,unmap}
API instead of deferencing junk pointers in the kernel. I've had them queued
locally for a while, so Robin and I have given them a fair workout.

Thanks,

Will
