    Subject[PATCH] edac: Add code to handle new MCE signatures for new models of Fam15h
    Date
    There are some newer error signatures in Family 15h models 30h-3fh.
    Code has been added in the patch to support these new signatures.

    Patch has been tested on Fam15h using mce_amd_inj facility and
    has been verified to work correctly.
