[GIT PULL] iommu/arm-smmu: Fixes for 4.8
From: Will Deacon <hidden>
Date: 2016-08-19 16:02:31
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
