nmi_watchdog: Fix undefined 'apic' build bug

Browse source

Ingo provided me a config that fails to compile with:

  arch/x86/built-in.o: In function
  `arch_trigger_all_cpu_backtrace': (.text+0x17e78): undefined
  reference to `apic' make: *** [.tmp_vmlinux1] Error 1

I realized I changed the compile behaviour of the nmi code by
not wrapping it with CONFIG_LOCAL_APIC.  To fix this I add a
compile check for ARCH_HAS_NMI_WATCHDOG around
arch_trigger_all_cpu_backtrace.
