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

Pull RAS updates from Ingo Molnar:
 "The main changes in this cycle were:

   - add the 'Corrected Errors Collector' kernel feature which collect
     and monitor correctable errors statistics and will preemptively
     (soft-)offline physical pages that have a suspiciously high error
     count.

   - handle MCE errors during kexec() more gracefully

   - factor out and deprecate the /dev/mcelog driver

   - ... plus misc fixes and cleanpus"
