    s390/irq: remove split irq fields from /proc/stat · 420f42ec
    Heiko Carstens authored
    Now that irq sum accounting for /proc/stat's "intr" line works again we
    have the oddity that the sum field (first field) contains only the sum
    of the second (external irqs) and third field (I/O interrupts).
    The reason for that is that these two fields are already sums of all other
    fields. So if we would sum up everything we would count every interrupt
    This is broken since the split interrupt accounting was merged two years
    ago: 052ff461 "[S390] irq: have detailed
    statistics for interrupt types".
    To fix this remove the split interrupt fields from /proc/stat's "intr"
    line again and only have them in /proc/interrupts.
    This restores the old behaviour, seems to be the only sane fix and mimics
    a behaviour from other architectures where /proc/interrupts also contains
    more than /proc/stat's "intr" line does.
