alnoconfig complains: arch/x86/kernel/setup.c: In function ‘setup_arch’: arch/x86/kernel/setup.c:917: error: implicit declaration of function ‘early_parse_srat’ because early_parse_srat is not declared for !CONFIG_ACPI. Moreover it is defined only for CONFIG_ACPI_NUMA. I am not sure what is the correct way to fix this but I guess that providing an empty definition for !CONFIG_ACPI_NUMA is OK.
