Seems that firmware only support to report the APEI status, by the Microsoft
WHEA defined UUID "ed855e0c-6c90-47bf-a62a-26de0fc5ad5c"
Kernel expects the _OSC method following the ACPI spec Platform-Wide OSPM
Capabilities UUID(0811B06E-4A27-44F9-8D60-3CBBC22E7B48)
So, when the kernel driver, function acpi_bus_osc_support() in
drivers/acpi/bus.c , checks the platform-Wide OSPM Capabilities with it's UUID,
got the invalid UUID, because firmware ACPI \_SB_:_OSC method checks the
Microsoft WHEA defined UUID.
Although, the Microsoft WHEA defined UUID also be handled by the kernel
driver, function apei_osc_setup() in acpi/apei/apei-base.c, so it should
not have any problems. I still suggest that the firmware implement the
Platform-Wide OSPM Capabilities UUID defined on the ACPI spec, because
it covers the APEI capabilities define.
