We don't enable ftrace for vdso, so I suspect objtool run above will be

I just checked without the series: recordmcount isn't run for VDSO, so
objtool shouldn't be run either when the series is applied.
Agree. I was only pointing out that it would be harmless, but it is good
to ensure objtool is skipped for files/directories where ftrace isn't
enabled. recordmcount keys off the presence of CC_FLAGS_FTRACE, and we
should do the same for 'objtool --mcount'.
