Hi Tyler,

I have a question for below code.

when it is SEA synchronized abort, why here inject a asynchronous abort through kvm_inject_vabt(vcpu) instead of synchronized abort? seem the original kvm source code is also do that, so I am confused about that.
thanks .

If the SEA was properly handled, then sea_status will avoid injecting 
the vabt. I'm going to just return after the SEA handling in the next 
patch though.

Thanks,
Tyler
