'irq_domain' depends on hard irqs, so for the architectures which have no hard irqs, but still need mfd (e.g. s390), need disable the related code, or can not pass compiling.
The related commit: "c94bb23 mfd: Make MFD core code Device Tree and IRQ domain aware" The related error: (with allmodconfig under s390) ERROR: "irq_create_mapping" [drivers/mfd/mfd-core.ko] undefined!
