arm/smmu: Use irqsafe spinlock for domain lock (2014-02-20 13:04:47 +0100)
----------------------------------------------------------------
IOMMU Fixes for Linux v3.14-rc3
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.
