KVM: Move KVM_IRQ_LINE to arch-generic code
Handle KVM_IRQ_LINE and KVM_IRQ_LINE_STATUS in the generic kvm_vm_ioctl() function and call into kvm_vm_ioctl_irq_line(). This is even more relevant when KVM/ARM also uses this ioctl. Signed-off-by: Christoffer Dall <c.dall@virtualopensystems.com> Signed-off-by: Avi Kivity <avi@redhat.com>
