Seems like that function only exists when CONFIG_NMI_IPI is defined.
Problem introduced by commit 5cc05910f26e6fd6da15f052f86f6150e4b91664
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/arch/powerpc/kernel/stacktrace.c?h=next-20180614&id=5cc05910f26e6fd6da15f052f86f6150e4b91664
What do you recommend to fix that ?
We could just do smp_call_function in the case we have no NMI_IPI?
???
Can you detail what you have in mind ? Do smp_call_function() to call
what ? Instead of the call to smp_send_safe_nmi_ipi() ?
Thanks
