It does! Thanks for the explanation and for the fix. I wonder why nobody
noticed and complained about that since v5.6.

Hi Steven,
At least on s390 since commit cbc3b92ce037 ("tracing: Set kernel_stack's
caller size properly") kernel stack trace contains 8 garbage values in the end.
I assume those are supposed to be filled by ftrace_trace_userstack, which is
only implemented on x86.

-Wnested-externs for perf like we did for the objtool. Or since we got
BUILD_BUG() implementation in tools simply disable -Wnested-externs for
all tools altogether? By throwing it out of EXTRA_WARNINGS.
