I failed to mention, the machine is an Apple iMac G5 "PowerMac8,1", PPC970FX @
1600MHz. (https://everymac.com/systems/apple/imac/specs/imac_g5_1.6_17.html)

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.
