Cover letter [PATCH 0/3] KVM: Improve IRQ assignment for device passthrough
Three patches to improve "classic" device assigment /wrt IRQs. Highlight is the last one that resolves the host IRQ sharing issue for all PCI 2.3 devices. Quite essential when passing non-MSI-ready devices like many USB host controllers.
