Right.  Hence, acpi_backlisted() still declares the list as
'acpi_blacklist[]'.

The term "oem" represents data types of the structure, oem_id[],
oem_table_id[], and oem_revision, which are defined by the ACPI spec.  

ghes_edac uses this structure as a while-list, so the term backlist is
misleading.  intel_pstate also uses it to list the platforms that do
not need OS control.
