Pull MCE updates from Tony Luck:
"There is a enhanced error logging mechanism for Xeon processors.
Full description is here:
http://www.intel.com/content/www/us/en/architecture-and-technology/enhanced-mca-logging-xeon-paper.html
This patch series provides a module (and support code) to
check for an extended error log and print extra details about
the error on the console.
