I don't really care for this part, as it seems somewhat ugly. But this
patch does appear to solve your issue, and I can't think of a prettier way
to do this.
So, I will reluctantly ack it.
If anything, please add a comment above saying that architectures may need
to override this function, and when doing so, they will define their own
ftrace_cmp_recs.
