hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4PM10 CVE: NA -------------------------------- APEI claimed ras error as a firmware-first notification. But we missing process it in kernel mode after commit 8fcc4ae6faf8 ("arm64: acpi: Make apei_claim_sea() synchronise with APEI's irq work"). We should call apei_claim_sea no mater in user or kernel mode.
