Merge tag 'iommu-fixes-v3.14-rc3' of git://git./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"
