    [S390] fix mismatch in summation of I/O IRQ statistics · de400d6b
    Peter Oberparleiter authored
    Current IRQ statistics support does not show detail counts for I/O
    interrupts which are processed internally only. The result is a
    summation count which is way off such as this one:
    
               CPU0       CPU1       CPU2
    I/O:       1331        710        442
    [...]
    QAI:         15         16         16   [I/O] QDIO Adapter Interrupt
    QDI:          1          0          0   [I/O] QDIO Interrupt
    DAS:        706        645        381   [I/O] DASD
    C15:         26         10          0   [I/O] 3215
    C70:          0          0          0   [I/O] 3270
    TAP:          0          0          0   [I/O] Tape
    VMR:          0          0          0   [I/O] Unit Record Devices
    LCS:          0          0          0   [I/O] LCS
    CLW:          0          0          0   [I/O] CLAW
    CTC:          0          0          0   [I/O] CTC
    APB:          0          0          0   [I/O] AP Bus
    
    Fix this by moving I/O interrupt accounting into the common I/O layer.
