> 主题: [PATCH v11 1/6] ACPI: add APEI/HEST/CPER structures and macros
>
> (1) Add related APEI/HEST table structures and macros, these
> definition refer to ACPI 6.1 and UEFI 2.6 spec.
> (2) Add generic error status block and CPER memory section
> definition, user space only handle memory section errors.
