Not sure if we can have the above check here unconditionally. Currently I can see there are 2 other users of acpi_parse_entries i.e. PCC and NUMA. So may be it can be made conditional or return success for non-MADT tables from bad_madt_entry ? Other than that, you can add for ARM64 specific parts: Reviewed-and-tested-by: Sudeep Holla <sudeep.holla@xxxxxxx> Regards, Sudeep -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
