Similar to the atomic revert, you are explaining why the revert but not the 
consequences. I think this is quite important to have them outline in the 
commit message as it looks like it means the SMMU driver would not scale.

Ok I will add.

Once XArray is implemented in XEN this patch can be added in XEN.

What's the plan for that?

As of now there is no plan for Xarray from our side.
Do we have requirement for Xarray implementation in XEN ?

That's going to depend on the consequence of reverting this patch.
