Merge tag 'iommu-fixes-v5.15-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull iommu fixes from Joerg Roedel:

 - Intel VT-d:
     - PASID leakage in intel_svm_unbind_mm()
     - Deadlock in intel_svm_drain_prq()

 - AMD IOMMU: Fixes for an unhandled page-fault bug when AVIC is used
   for a KVM guest.

 - Make CONFIG_IOMMU_DEFAULT_DMA_LAZY architecture instead of IOMMU
   driver dependent
