Merge tag 'iommu-fixes-v5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fixes from Joerg Roedel:
- revert an Intel VT-d patch that caused boot problems on some machines
- fix AMD IOMMU interrupts with x2apic enabled
- fix a potential crash when Intel VT-d domain allocation fails
- fix crash in Intel VT-d driver when accessing a domain without a
flush queue
- formatting fix for new Intel VT-d debugfs code
- fix for use-after-free bug in IOVA code
- fix for a NULL-pointer dereference in Intel VT-d driver when PCI
hotplug is used
- compilation fix for one of the previous fixes
