Hi all,

Here's a v3 with most of the additional cleanup as discussed, which makes
the diffstat look pretty horrific, but I think it does work out for the
better in the end. I did write a further patch converting "(1 << x)" into
"BIT(x)", but comes out as a +70/-70 diff of pure churn which somehow
manages to make the codegen in arm_smmu_device_probe() worse, so it got
git reset --hard into oblivion.

Robin.
