 - Generalization of AMD MCE bank names and some minor error reporting
   improvements.

 - EDAC core cleanups and simplifications, from Wei Yongjun.

 - amd64_edac fixes for sysfs-reported values, from Josh Hunt.

 - some heavy amd64_edac error reporting path shaving, leading to
   removing a bunch of code.

 - amd64_edac error injection method improvements.
