I tried something like that, but the CFLAGS games the tracing code
does made my thing result in
kernel/trace/Makefile:20: *** Recursive variable 'KBUILD_CFLAGS'
references itself (eventually). Stop.
but yes, if you have the magic fingers to make it work, limiting the
-Wno-frame-address to just the tracing code sounds like the
RightThing(tm).
