Pull RAS updates from Ingo Molnar:
 "The main changes were:

   - Lots of enhancements for AMD SMCA (Scalable MCA
     features/extensions) systems: extract, decode and print more
     hardware error information and add matching support on the
     injection/testing side as well. (Yazn Ghannam)

   - Various MCE handling improvements on modern Intel Xeons. (Tony
     Luck)

   - Plus misc fixes and enhancements"
