Subject[PATCHv2] x86, mce: Kernel does full decoding for AMD, others still need /dev/mcelog reports
Date
We should only believe a NOTIFY_STOP on an AMD system. For others
we need to provide the error record out to a user level decoder
via /dev/mcelog.

v2: Boris says: "on AMD, mcelog is not needed"
