    [S390] irq: external interrupt code passing · fde15c3a
    Heiko Carstens authored
    The external interrupt handlers have a parameter called ext_int_code.
    Besides the name this paramter does not only contain the ext_int_code
    but in addition also the "cpu address" (POP) which caused the external
    interrupt.
    To make the code a bit more obvious pass a struct instead so the called
    function can easily distinguish between external interrupt code and
    cpu address. The cpu address field however is named "subcode" since
    some external interrupt sources do not pass a cpu address but a
    different parameter (or none at all).
