Hi Joerg,
Please pull the following arm-smmu fixes for 3.14.
The brief summary is:
- Andreas Herrmann took the driver for a run with a real SATA
controller, which caused the new mutex-based locking to explode
since we require mappings in atomic context
- Yifan fixed an issue with the page table creation, which then caused
breakages with the way in which we flush descriptors out to the
table walker
- I ran the driver on a system where the SMMU is hooked into a
coherent interconnect for table walks, and noticed a shareability
mismatch between the CPU and the SMMU
These issues are all fixed here and have been tested on both arm and
arm64 based systems.
Cheers,
Will
