Merge tag 'iommu-fixes-v3.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fixes from Joerg Roedel:
"The fixes are only for the ARM-SMMU driver. Here is the summary from
Will Deacon:
- 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.
Besides that I put a fix on-top to make the spinlock irq-safe, so that
the code-paths can be used in the DMA-API"
