Commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in
apci_init()") introduced a bug that ghes_edac_register() would be invoked
before edac_init(). Because at that time, the bus "edac" hasn't been even
registered, this created sysfs /devices/mc0 instead of
/sys/devices/system/edac/mc/mc0 on an Ampere eMag server.
The solution is modularizing the ghes_edac driver.
Changelog:
v2:
- add acked-by tag of Patch 1 from Ard
- split the notifier patch
- add 2 patch to get regular drivers selected when ghes edac is not loaded
- fix an errno in igen6 driver
- add a patch to fix the sparse warning of ghes
- refine the commit logs
