checkpatch probably will complain due to too long lines
you can use:
void build_append_ghe...
         uint32_t error_severity, uint16_t revision,
         ...

                                            ^^^
use QemuUUID instead, see vmgenid_build_acpi

same as section_type

instead of loop use g_array_insert_vals()

that's not part of 'Table 17-13'
where does it come from?
