No, not replace.

In ghes.c:

- add ghes_edac_driver_is_preferred()
- remove ghes_edac_register() and _unregister() calls from there. Make them proper module
init/exit functions.
- Make ghes_edac.c a proper module - i.e., get rid of this thing:

config EDAC_GHES
bool "Output ACPI APEI/GHES BIOS detected errors via EDAC"
depends on ACPI_APEI_GHES && (EDAC=y)
^^^^^^^^

Not at all...

Yes, I think you do. Lemme write something and you can finish it/test
it.
