| |
From: Arnd Bergmann <arnd@arndb.de>
When CONFIG_SMP is disabled, the prototype for safe_smp_processor_id() is hidden, which causes a W=1 warning:
/home/arnd/arm-soc/arch/x86/kernel/apic/ipi.c:316:5: error: no previous prototype for 'safe_smp_processor_id' [-Werror=missing-prototypes]
Since there are no callers in this configuration, just hide the definition as well.
