This series adds an Adreno SMMU implementation to arm-smmu to allow GPU hardware
pagetable switching.

The Adreno GPU has built in capabilities to switch the TTBR0 pagetable during
runtime to allow each individual instance or application to have its own
pagetable.  In order to take advantage of the HW capabilities there are certain
requirements needed of the SMMU hardware.

"capabilities" is a polite way of putting it ;)

Anyway, modulo two design comments, I think this is about as nice as we're
going to get this. Thanks for persevering, and sorry that you have to deal
with such dreadful hardware.

Hopefully the next version will be the one, although I'd like Robin to take
a quick look as well if he gets a chance.

Will
