> amd64_edac gets its node count and DF devices from the AMD northbridge
> cache. Since commit 49b96fc0dddc ("x86/amd_nb: Simplify function 3
> search"), the cache finds function 3 only at the fixed PCI slots
> 0x18 + N. Hygon DF devices are not at those slots, so the cache is
> discarded on Hygon and amd64_edac_init() returns -ENODEV at its
> amd_nb_num() check.
>
> Remove the Hygon match and the empty Family 0x18 case. MCE decoding
> in mce_amd.c is separate and unchanged. Hygon memory controller support
> will use the Hygon node interfaces in a separate series.
