Which is a wonderful demonstration for why duplicating such a large
function from branch.c was a baaad thing to do.

Maneesh, can you refactor the code to share everything that was copied
from __compute_return_epc() can be shared with kprobes?  Idealy make
everything a two part series, first one patch to refactor branch.c and
the 2nd patch to deal with kprobes.

Thanks,
