This patch looks very architecture specific. Is there a generic ftrace
issue you have with this? "out-of-range" issues are specific to an
architecture (x86 doesn't have this issue).

You need the RISC-V maintainers to review and accept this patch. I don't
see anything specific to generic ftrace infrastructure here, which is what
I maintain.
