Hello, Following the 'dual' IRQ backend, this series adds KVM support to the XIVE interrupt mode.
The first patches introduce the XIVE KVM device, state synchronization and migration support under KVM. The second part of the patchset modifies the XICS and XIVE interrupt models to add KVM support to the 'dual' IRQ backend. This is a first round to check that the interfaces with Linux/KVM are well in place.
