Refer to the ACPI SPEC r6.5 for the more detailed description. This patch is an effective supplement to _HPP/_HPX method when the Firmware does not support the _HPP/_HPX method and can be specially configured for the AER register of the specific device. --- v1->v2: - Move the definition of structure "hest_parse_aer_info" to file apei.h.
