I'm not sure how to measure performance in this case. You'd need to
measure access times to each device before and after the patch, and
average them.
Try registering ~100 PIO ioeventfds, and writing a test case which
accesses a PIO port that misses all of them, in a loop. Measure your
exit rate before an after.
