The NMI infrastructure cannot currently be used in loadable modules:
ERROR: modpost: "free_nmi" [drivers/soc/fujitsu/a64fx-diag.ko] undefined!
ERROR: modpost: "request_nmi" [drivers/soc/fujitsu/a64fx-diag.ko] undefined!
ERROR: modpost: "enable_nmi" [drivers/soc/fujitsu/a64fx-diag.ko] undefined!
Disable this for now to make allmodconfig build again. We may revisit
this and export those symbols instead in the future.

Register the NMI/IRQ corresponding to the A64FX's device definition
dedicated to diagnostic interrupts, so that when this interrupt is
sent using the BMC, it causes a panic. This can be used to obtain
a kernel dump.
