1648 This must be called whenever userspace has changed an entry in the shared

2971 This ioctl allows userspace to retrieve the complete state of all currently

2986 If -ENOBUFS is returned the buffer provided was too small and userspace
3002 This ioctl allows userspace to set the complete state of all cpu-local

3013 The userspace memory referenced by buf contains a struct kvm_s390_irq
3156 operations are complete (and guest state is consistent) only after userspace

3329 IOAPIC is implemented in userspace (i.e. KVM_CAP_SPLIT_IRQCHIP is enabled);
3330 the userspace IOAPIC should process the EOI and retrigger the interrupt if
