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

Pull x86/MCE update from Ingo Molnar:
 "Various MCE robustness enhancements.

  One of the changes adds CMCI (Corrected Machine Check Interrupt) poll
  mode on Intel Nehalem+ CPUs, which mode is automatically entered when
  the rate of messages is too high - and exited once the storm is over.

  An MCE events storm will roughly look like this:

   [ 5342.740616] mce: [Hardware Error]: Machine check events logged
   [ 5342.746501] mce: [Hardware Error]: Machine check events logged
   [ 5342.757971] CMCI storm detected: switching to poll mode
   [ 5372.674957] CMCI storm subsided: switching to interrupt mode

  This should make such events more survivable"
