Pull edac updates from Mauro Carvalho Chehab:
 "Some fixes and additions to the EDAC driver used on modern Intel x86
  CPUs.  It includes support for Broadwell EP/EX platforms and fixes for
  motherboards with more than 2 CPU sockets"

* tag 'edac/v4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac:
  sb_edac: support for Broadwell -EP and -EX
  sb_edac: Fix support for systems with two home agents per socket
  sb_edac: Fix a typo and a thinko in address handling for Haswell
  EDAC: Remove arbitrary limit on number of channels
