Merge tag 'edac_for_4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp
Pull EDAC updates from Borislav Petkov:
"Nothing earth-shattering - just the normal development flow of
cleanups, improvements, fixes and such.
Summary:
- i31200_edac: Add Kabylake support (Jason Baron)
- sb_edac: resolve memory controller detection issues on asymmetric
setups with not all DIMM slots being populated (Tony Luck and Qiuxu
Zhuo)
- misc cleanups and fixlets all over"
