    xen: event channel remapping for emulated MSIs
    Linux PV on HVM guests remap all the MSIs onto event channels,
    including MSIs corresponding to QEMU's emulated devices.  This patch
    makes sure that we handle correctly the case of emulated MSI that have
    been remapped, sending a pirq to the guest instead.
