Just use ARCH_HAS_ style and and hard select ARCH_HAS_ACPI_APEI_NMI for x86. There is no need for the ACPI_APEI_GHES dependency then. -Robert -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Currently APEI depends on x86 architecture. It is because of NMI hardware error notification of GHES which is currently supported by x86 only. However, many other APEI features can be still used perfectly by other architectures. This commit adds ACPI_APEI_NMI which will be used in next patches to isolate NMI related code in ghes.c file. Only NMI error notification feature depends on x86 and it is selected by default for x86 arch.
