I've investigated what was happening with this one.
Everything is all right.
What was happening was that the absence of the patch
"fix value of label statement" created a lot of dead OP_SETVAL.
The patch "fix killing of OP_SETVAL instructions" did its job
but the code was wrong anyway and created a lot of changes
in kernel's allyesconfig's output.

So now that "fix value of label statement" is applied, you can
safely apply "fix killing of OP_SETVAL instructions" somewhere
after it, it won't create useless noise.
