    [S390] zcore: Fix reipl device detection · 76ef964c
    Michael Holzheu authored
    The reipl device information is passed from the kernel to zfcpdump
    using a pointer in the lowcore (0xe00) that points to the reipl
    information Currently if that pointer is not zero, we copy the reipl
    information. If the pointer is not initialized and points outside
    the accessible memory, it can happen that the memory copy fails.
    In that case we currently stop the initialization of zcore which leads
    to a failing kernel dump. The correct behavior is to disable the reipl
    after dump and continue with zcore intialization.
