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
