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" * 'x86-mce-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mce: Provide boot argument to honour bios-set CMCI threshold x86, MCE: Remove unused defines x86, mce: Enable MCA support by default x86/mce: Add CMCI poll mode x86/mce: Make cmci_discover() quiet x86: mce: Remove the frozen cases in the hotplug code x86: mce: Split timer init x86: mce: Serialize mce injection x86: mce: Disable preemption when calling raise_local()
