E.g. on Koelsch (R-Car M2-W): 200: 0 0 gpio-rcar 6 Edge SW36 IPI0: 0 0 CPU wakeup interrupts IPI1: 0 0 Timer broadcast interrupts IPI2: 1701 2844 Rescheduling interrupts IPI3: 10338 21181 Function call interrupts IPI4: 0 0 CPU stop interrupts IPI5: 651 825 IRQ work interrupts IPI6: 0 0 completion interrupts Err: 0 Fix this by adopting the same solution as used on arm64.
