No, it switches off firmware first mode for correctable errors because
of buggy BIOSes - 9ad95879cd1b2 (what else...)

This glob value resides in x86 ACPI code and has meaning only for MCE
related mechanism,

Of course it doesn't!

that is why I have moved it under hest_parse_cmc.

See APEI section in the ACPI spec "18.4 Firmware First Error Handling."

Regardless of what your version of APEI does, you actually shouldn't
need to touch acpi_disable_cmcff at all as it not arch-specific.


You are right! I will fix that big misunderstanding from my side in next patch version.

Thanks,
Tomasz
