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" * tag 'iommu-fixes-v3.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: arm/smmu: Use irqsafe spinlock for domain lock iommu/arm-smmu: fix compilation issue when !CONFIG_ARM_AMBA iommu/arm-smmu: set CBARn.BPSHCFG to NSH for s1-s2-bypass contexts iommu/arm-smmu: fix table flushing during initial allocations iommu/arm-smmu: really fix page table locking iommu/arm-smmu: fix pud/pmd entry fill sequence
