There are a lot of problems with our NVIC priority handling
right now. You might like to take a look at the patch set that
Michael Davidsaver sent out earlier this month:
https://lists.nongnu.org/archive/html/qemu-devel/2015-11/msg01542.html
That has some problems but I think it's probably the way we're
going to go to fix up the NVIC.
