I can inject the event as HW interrupt on vector greater then 32 but not

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.
