 Hello!

 Andre, you never replied to my last comment to the previous series. Are you going to do the same
change in your MSI API? Otherwise:
1. KVM_IRQ_LINE - we have completely own convention. Well, this was already done before us, we
cannot fix it.
2. KVM_SIGNAL_MSI - we use VALID_DEVID flag plus devid
3. KVM_SET_GSI_ROUTING - we use KVM_IRQ_ROUTING_EXTENDED_MSI plus devid

 Don't (2) and (3) together still look bad? Since we agreed on not using flags, i would suggest to
have KVM_SIGNAL_EXTENDED_MSI counterpart, which also doesn't use flags.
 I know, we were already talking about it, so, if this gets ignored for the second time, i assume
the Architects decided that fancy APIs are cool, and i promise to stop this.
