Hi,
I have some problems compiling the last qemu-kvm git tree, the first is 
about this patch:

http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=commit;h=3cdbd5f0b533901b43279df40107e2e235255244 


================================
CC    ppc64-softmmu/virtio-pci.o
/usr/src/qemu-kvm/hw/virtio-pci.c: In function 'virtio_pci_mask_notifier':
/usr/src/qemu-kvm/hw/virtio-pci.c:436: error: invalid use of undefined 
type 'struct kvm_irq_routing_entry'
/usr/src/qemu-kvm/hw/virtio-pci.c:436: error: dereferencing pointer to 
incomplete type
================================

Then if I remove this patch I have new problems:

======================================

=================================================
and so on.

In attach all info abount my env.

If someone need a ppc970 as test environment I can provide him a remote 
access to one or two test machine.

Thanks,
Giuseppe.
