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"
