This commit abstracts MCE calls and provides weak corresponding default implementation for those architectures which do not need arch specific actions. Each platform willing to do additional architectural actions should provides desired function definition. It allows us to avoid wrap code into #ifdef in generic code and prevent new platform from introducing dummy stub function too. Initially, there are two APEI arch-specific calls: - arch_apei_enable_cmcff() - arch_apei_report_mem_error() Both interact with MCE driver for X86 architecture.
