--- Comment #2 from A. Wilcox (awilfox at adelielinux.org) ---
This is because CONFIG_HARDLOCK_DETECTOR is on and CONFIG_NMI_IPI is off.

CONFIG_HARDLOCK_DETECTOR pulls in CONFIG_PPC_WATCHDOG, which unconditionally
uses smp_send_nmi_ipi (and I believe requires such to work properly). 
CONFIG_PPC_WATCHDOG doesn't depend on CONFIG_NMI_IPI which it probably should. 
And then CONFIG_HARDLOCK_DETECTOR_ARCH should probably depend on CONFIG_NMI_IPI
or CONFIG_PPC_WATCHDOG.
