Merge branch 'x86-mce-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 RAS changes from Ingo Molnar:
 "The biggest change adds support for Intel 'CPER' (UEFI Common Platform
  Error Record) error logging, which builds upon an enhanced error
  logging mechanism available on Xeon processors.

  Full description is here:

    http://www.intel.com/content/www/us/en/architecture-and-technology/enhanced-mca-logging-xeon-paper.html

  This change provides a module (and support code) to check for an
  extended error log and prints extra details about the error on the
  console"
