[GIT PULL] iommu/arm-smmu: updates for 3.15

[Will Deacon]

Hi Joerg,

Please can you pull the following arm-smmu changes for 3.15?

The main changes are for accessing the buggy Calxeda SMMU, which is wired
as secure despite being non-secure. Unfortunately, the apparent demise
of Calxeda means that Andreas is no longer working on this, so I had to
extract what I could from a larger patchset (which wasn't yet ready for
merging in its entirety).

On my side, there's some cosmetic changes after Joerg fixed some locks
to use spin_lock_irq{save,restore} and also an optimisation to restrict
the scope of our barrier when publishing page tables (now that ARM64 can
accept the option).

Cheers,

Will
