agree with you, we need to clean this up. I don't believe all the flags are
necessary at the moment (given the fact that they are introduced by
host-MSI-to-guest-INTx translation). But it is still OK for me if they did
not cause trouble and were not wrongly used.
I wonder whether the original patch has carefully considered the usage of
these flags when it tried to introduce these flags by nature.

Basically, I think it is up to you to decide their (flags) future. You are
already very careful on this. :)
