stacktrace.c:(.text+0x1b0): undefined reference to `.smp_send_safe_nmi_ipi'

See http://kisskb.ellerman.id.au/kisskb/buildresult/13395345/ for details

Seems like that function only exists when CONFIG_NMI_IPI is defined.

Problem introduced by commit 5cc05910f26e6fd6da15f052f86f6150e4b91664

What do you recommend to fix that ?
