Subject: MCE, AMD: Dump CPU f/m/s triple with the error
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f89f8388cd11faa8e77992cb11ab44ac9a6abf4f;p=deliverable%2Flinux.git

MCE, AMD: Dump CPU f/m/s triple with the error

It is very useful to have the family/model/stepping with the reported
error so dump it. This saves us asking the bug reporter about it.
