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
