[PATCH 1/9] x86/mce-inject: Make it depend on X86_LOCAL_APIC

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

... and get rid of the annoying:

  arch/x86/kernel/cpu/mcheck/mce-inject.c:97:13: warning: âmce_irq_ipiâ
  defined but not used [-Wunused-function]
   static void mce_irq_ipi(void *info

when doing randconfig builds.
