Most architectures have ftrace related stuff in arch/*/kernel/ftrace.c
but powerpc has it spread in multiple files located in
arch/powerpc/kernel/trace/
In several architectures, there are also additional files containing
'ftrace' as part of the name but with some prefix or suffix.

Use wildcards to enlarge coverage.
