 - Handle ERR_PTR() returns in __iommu_domain_alloc() path

 - Update MAINTAINERS entry for Qualcom IOMMUs

 - Printk argument fix in device tree specific code

 - Several Intel VT-d fixes from Lu Baolu:
     - Do not support enforcing cache coherency for non-empty domains
     - Avoid devTLB invalidation if iommu is off
     - Disable PCI ATS in legacy passthrough mode
     - Support non-PCI devices when clearing context
     - Fix incorrect cache invalidation for mm notification
     - Add MTL to quirk list to skip TE disabling
     - Set variable intel_dirty_ops to static
