nmi is broken?

[OGAWA Hirofumi <hirofumi@xxxxxxxxxxxxxxxxxx>]

Hi,

I noticed recently NMI on guest kernel is not working well.  host/guest
kernel is 2.6.39-rc4, and using vmx.

And test code is something like the following:

	local_irq_disable();
	for (i = 0; i < 10; i++) {
		int cpu = get_cpu();
		printk("%s: nmi %u, lapic %u\n", __FUNCTION__,
			nmi_count(cpu), irq_stat[cpu].apic_timer_irqs);
		mdelay(1000);
		put_cpu();
	}

the result is both of nmi and lapic are not increased. If I used
-no-kvm-irqchip, it works fine (increase nmi only). So, it seems to be
the bug of kvm driver side.

Ideas?
