x86: APIC/SMP: Downgrade the NMI watchdog for "noapic"
If configured to use the I/O APIC, the NMI watchdog is deemed to fail if the chip has been deactivated as a result of "noapic". Downgrade to the local APIC watchdog similarly to what is done for the UP case. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
