Either way works, but given syzcaller could potentially trigger these
holes (it did find a whole bunch of 'interesting' problems in the early
noinstr days) I'd prefer them earlier rather than later.

OTOH, the objtool patches that keep triggering them all over the place
are still in objtool/core for the next cycle.
