What about untangling this into entirely separate versions instead
of the ifdef mess? Also the export does not seem to be needed at all.
Ok, I see that you do that later, sorry.
In v2, I drop the untangling patch, because the series completely
dismantles flush_instruction_cache() so there is no need for an
ephemeral untanggled version of it.
