Lots of 'literal placed after use' messages in all xtensa builds,
Interestingly, it looks like the culprit is not the placement of
.text.unlikely, but the changed placement of .text.hot (which the
patch states wasn't necessary).

Yeah, exactly the type of change I had in mind posting this:

BTW with that sed script it works.
