I can inject the event as HW interrupt on vector greater then 32 but not
go through APIC so EOI will not be required. This sounds
and I am not sure kernel has entry point code for this kind of event, it
has one for exception and one for interrupts that goes through __do_IRQ()
which assumes that interrupts should be ACKed.

Further, we start to interact with the TPR; Linux doesn't use the TPR or
cr8 but if it does one day we don't want it interfering with apf.

That's not an issue is it? The guest will tell the host what
vector to use for pseudo page faults.

And kill 15 other vectors?
