[GIT PULL] iommu/arm-smmu: Updates for 4.10

[Will Deacon]

Hi Joerg,

Please pull these arm-smmu updates for 4.10. The bulk of the changes here
are the IORT support from Lorenzo, which also touches ACPI and PCI core
code. Rafael and Bjorn have acked the relevant changes, but it makes sense
to send it via you to avoid conflicts with the ARM SMMU drivers, which are
modified to work with ACPI-based probing.

The other changes are largely cosmetic (constification and cleanup), but
the MMU-500 configuration change from Nipun results in a hefty performance
boost in bypass mode.

Thanks,

Will
