    Subject[patch] edac i5000: fix pointer math in i5000_get_mc_regs()
    "pvt->ambase" is a u64 datatype.  The intent here is to fill the first
    half in the first call to pci_read_config_dword() and the other half in
    the second. Unfortunately the pointer math is wrong so we set the wrong

    I don't have the hardware to test this. Please review carefully.
