See once on - we then have a version='host' and we're good to go.
Of course, as I'm typing I realize that we wouldn't print out
version='host' if it were the default... But that may not be a bad
thing - although we could.
Just throwing some ideas out. Obviously the series works as is, but you
were more involved in the qemu gic discussion so you can go with Cole's
ACK and I'm fine with that.
