Syndrome information is no longer contained in MCA_STATUS for SMCA systems but in a new register - MCA_SYND. Add a synd field to struct mce to hold MCA_SYND register value. Add it to the end of struct mce to maintain compatibility with old versions of mcelog. Also, add it to the respective tracepoint.
