According to the ACPI specification, firmware is not required to provide the Hardware Error Source Table (HEST). When HEST is not present, the following superfluous message is printed to the kernel boot log - [ 3.460067] GHES: HEST is not enabled! Extend hest_disable variable to track whether the firmware provides this table and if it is not present skip any log output. The existing behaviour is preserved in all other cases.
