x86/mce, EDAC/mce_amd: Print MCA_SYND and MCA_IPID during MCE on SMCA systems The MCA_SYND and MCA_IPID registers contain valuable information and should be included in MCE output. The MCA_SYND register contains syndrome and other error information, and the MCA_IPID register will uniquely identify the MCA bank's type without having to rely on system software.
