cpr-transfer may lose a VFIO interrupt because the KVM instance is
destroyed and recreated. If an interrupt arrives in the middle, it is
dropped. To fix, disable pended interrupts during cpr save, and pick
up the pieces. In more detail:
Stop the VCPUs. Call kvm_irqchip_remove_irqfd_notifier_gsi

Not all fields in the SMMU IDR registers are meaningful for userspace.
Only the following fields can be used:

- IDR3: BBML, RIL

On ARM, when a device is behind an IOMMU, its MSI doorbell address is

If an ESP command is issued in an incorrect mode then an illegal command

Clarify the logic in esp_transfer_data() to ensure that the deferred interrupt

can only be triggered for CMD_SEL, CMD_SELATN and CMD_TI commands. This should
already
be the case, but make it explicit to ensure the logic isn't triggered

Newer versions of Spice server should be able to accept dmabuf
