Most architectures have ftrace related stuff in arch/*/kernel/ftrace.c
but powerpc has spread in multiple files located in
arch/powerpc/kernel/trace/

Perhaps replace the above two with:
   F:   arch/*/*/ftrace*
   F:   arch/*/*/*/ftrace*

As we also have things like ftrace_32.S, ftrace_64.S

Maybe even add:

   F: arch/*/*/*_ftrace.*
   F: arch/*/*/*/*_ftrace.*

to catch the "entry_ftrace.S" and friends (needing the leading "_" to not
get confused by any "bpftrace" files).

?

But in reality, I'm only a reviewer for ftrace in the archs. It really is
maintained by the arch maintainers. But it is still good that I get Cc'd on
any ftrace arch related changes.
