The right thing to do here is copy the exitintinfo->eventinj only if
eventinj.fields.v==0. And to add a comment that in future the two events
should be 'merged' in the architecturally correct manner (e.g., turned into
#DF in some cases).

At least I *think* this is the right thing to do -- but now I think about
it, is it actually ever okay to copy a SWINT from exitintinfo into eventinj?
At the time the #PF vmexit happens, will EIP have been incremented across
the SWINT instruction? If not, does eventinj of a SWINT correctly cause EIP
to be incremented?

Yes please!

 Thanks,
