While you're editing that code, could you please also cut the spam if ECC is
actually disabled?  For example, a 2990WX with non-ECC RAM gets 1024 lines;
64 copies of:

[    8.186164] EDAC amd64: Node 0: DRAM ECC disabled.
[    8.188364] EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
                Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
                (Note that use of the override may cause unknown side effects.)
[    8.194762] EDAC amd64: Node 1: DRAM ECC disabled.
[    8.196307] EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
                Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
                (Note that use of the override may cause unknown side effects.)
[    8.199840] EDAC amd64: Node 2: DRAM ECC disabled.
[    8.200963] EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
                Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
                (Note that use of the override may cause unknown side effects.)
[    8.204326] EDAC amd64: Node 3: DRAM ECC disabled.
[    8.205436] EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
                Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
                (Note that use of the override may cause unknown side effects.)
