[GIT PULL] iommu/arm-smmu: Fixes for 4.8

[Will Deacon]

Hi Joerg,

As promised yesterday, here are a few ARM SMMU fixes for 4.8. I've added
a Fixes: line to each patch, so they should be good to go. The main changes
are:

  - Fix a couple of thinkos in the CMDQ error handling and short-descriptor
    page table code that have been there since day one
  - Disable stalling faults, since they may result in hardware deadlock
  - Fix an accidental BUG() when passing disable_bypass=1 on the cmdline

Cheers,

Will
