  i7core_edac: Fix compilation on 32 bits arch
  i7core_edac: scrubbing fixups
  EDAC: Correct Kconfig dependencies
  i7core_edac: return -ENODEV if no MC is found
  i7core_edac: use edac's own way to print errors
  MAINTAINERS: remove dropped edac_mce.* from the file
  i7core_edac: Drop the edac_mce facility
  x86, MCE: Use notifier chain only for MCE decoding
  EDAC i7core: Use mce socketid for better compatibility
  i7core_edac: Don't enable memory scrubbing for Xeon 35xx
  i7core_edac: Add scrubbing support
