Right now not. We may change that anyway in the future if needed.

Steven, how do we proceed with this small series?

Since there don't seem to be any objections, I'll repost with the
changed notrace define. However I think the whole stuff should go
upstream via the ftrace tree. Is that ok with you?

FWIW, the s390 gcc hotpatch feature was merged in the meantime:
