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"
