Merge tag 'iommu-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull iommu fixes from Will Deacon:
 "This is mainly all Intel VT-D stuff, but there are some fixes for AMD
  and ARM as well.

  We've also got the revert I promised during the merge window, which
  removes a temporary hack to accomodate i915 while we transitioned the
  Intel IOMMU driver over to the common DMA-IOMMU API.

  Finally, there are still a couple of other VT-D fixes floating around,
  so I expect to send you another batch of fixes next week.

  Summary:

   - Fix VT-D TLB invalidation for subdevices

   - Fix VT-D use-after-free on subdevice detach

   - Fix VT-D locking so that IRQs are disabled during SVA bind/unbind

   - Fix VT-D address alignment when flushing IOTLB

   - Fix memory leak in VT-D IRQ remapping failure path

   - Revert temporary i915 sglist hack now that it is no longer required

   - Fix sporadic boot failure with Arm SMMU on Qualcomm SM8150

   - Fix NULL dereference in AMD IRQ remapping code with remapping disabled

   - Fix accidental enabling of irqs on AMD resume-from-suspend path

   - Fix some typos in comments"
