On a system with less than 1000 interrupts, prec = 3, causing a
misalignment for the IPI interrupts. 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.
