I am confused. This change patches objtool to rename
rewind_stack_and_do_exit to rewind_stack_and_make_dead in the list
global_noreturns in tools/objtool/check.c
There is no other change to oops_end other than that renaming.
Did the robot somehow mange to run an old version of objtool while
building and this get this error?
I tried and I am not currently able to reproduce this error. Do you
have any additional pointers on how I might reproduce this?

Hi Eric,
The reproduce step in report based on a full build, I can reproduce the
warnings with the below command:
make W=1 O=build_dir ARCH=x86_64 SHELL=/bin/bash

Any chance you could do "make arch/x86/kernel/dumpstack.s" and send it
to me?
I want to see what code is in your oops_end.
It really does not make sense that simply renaming a function would
trigger this error.
I did a full build (on debian 10 with gcc-8.3.0) and I did not manage to
reproduce this. In a bit I will try with a newer debian and see if I
can get the issue to reproduce. Still it does not make sense to me
that a simple rename would trigger this error.

Thanks. What I was actually hoping for was the assembly code of
oops_end so I could understand the objtool error.
I have tracked it down now. I accidentally deleted a comma, which
caused C string concatenation which merged two symbols together,
and caused this warning.
What an annoying typo.

Recently the kbuild robot reported two new errors:
>> lib/kunit/kunit-example-test.o: warning: objtool: .text.unlikely: unexpected end of section
>> arch/x86/kernel/dumpstack.o: warning: objtool: oops_end() falls through to next function show_opcodes()
I don't know why they did not occur in my test setup but after digging
it I realized I had accidentally dropped a comma in
tools/objtool/check.c when I renamed rewind_stack_do_exit to
rewind_stack_and_make_dead.
Add that comma back to fix objtool errors.
