Merge tag 'edac_for_3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp

Pull EDAC fixes from Borislav Petkov:
 "Misc small fixes/improvements accumulated from the summer months,
  nothing earth-shattering.

  The mpc85xx_edac fix is tagged for stable but since it got confirmed
  only days before the final 3.17 release, I didn't rush a last minute
  pull request to you.  I hope that's ok as it will trickle down to
  stable anyway and we'll make sure it lands in 3.17-stable too"

* tag 'edac_for_3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp:
  mpc85xx_edac: Make L2 interrupt shared too
  amd64_edac: Modify usage of amd64_read_dct_pci_cfg()
  ppc4xx_edac: Fix build error caused by wrong member access
  EDAC: Fix mem_types strings type
