There is no way to change it more gradually than what I have done. At least, I cannot think of one.

so you're removing all the inline callchain implementation
in this patch and adding it back in following patches?
any chance you could change it gradualy? it's hard to track
in review if you added everything that you removed ;-)

The follow-up commits will make inline frames first-class citizens
in the callchain, thereby obsoleting all of this special code.
