Thanks. These look good. We're still trying to get our merge process
worked out, and tip/objtool/core is now pretty old, but these apply well

If there are no more comments I can fix up the few minor comments I had
and then try to get them merged after your other set (once Peter and I
figure out how to do that :-)
