I can gladly use `256 + KSYM_NAME_LEN` and add a comment ala "room for insn-encoding and a symbol name". Would that be acceptable? The alternative would be to try to dyn-alloc a buffer and increase it to the actual line-length?

John independently hit this issue again. Could we fix this? Going for
the `256 + KSYM_NAME_LEN` sounds good enough for the moment since it
would be a clear improvement, though I agree this could be cleaned up
further.

Sergio took the approach David suggested in a related patch [1], but
perhaps it is best to submit the fix on its own so that it is easier
to put it in. David, would you be so kind as to submit a v2 with that?
Hopefully x86 can pick it up, otherwise with an Acked-by I am happy to
take it too; and then Sergio can submit his patch on top again.

Thanks!
