Subject: linux-next: build failure in Linus' tree

Hi Linus,

With Linus' tree, today's linux-next build (x86_64 allmodconfig) failed
like this:

Caused by commit af9d220bac41 ("EDAC: Correct Kconfig dependencies").
Since CONFIG_EDAC_MCE is no longer selected most of the stuff in
linux/edac_mce.h is not available.  I have reverted that commit for today.
