From: Arnd Bergmann <[email protected]>
The now more verbose check found more architecture specific symbol
missing from the whitelist, during randconfig testing on s390
and 32-bit arm:
Unexpected symbols in kernel/trace/simple_ring_buffer.o:
U __aeabi_unwind_cpp_pr1
Unexpected symbols in kernel/trace/simple_ring_buffer.o:
U __s390_indirect_jump_r1
U __s390_indirect_jump_r10
U __s390_indirect_jump_r14
U __s390_indirect_jump_r2
U __s390_indirect_jump_r5
U __s390_indirect_jump_r7
U __s390_indirect_jump_r8
U __s390_indirect_jump_r9
make[6]: *** [/home/arnd/arm-soc/kernel/trace/Makefile:160:
kernel/trace/simple_ring_buffer.o.checked] Error 1
Add these to the list and keep it roughly sorted into sanitizer
and architecture symbols.
Fixes: 1211907ac0b5 ("tracing: Generate undef symbols allowlist for
simple_ring_buffer")

v2: add both s390 and arm symbols
