[PATCH] x86: hpet: Fix HPET timer + NMI watchdog panic

HPET doesn't use timer_interrupt() as interrupt handler now. So count of HPET interrupt isn't recorded in per_cpu(irq_stat, cpu).irq0_irqs. This confuses NMI watchdog when using HPET as tick device. Signed-off-by: Yan, Zheng ...

In a kvm virt guests, the perf counters are not emulated. Instead they return zero on a rdmsrl. The perf nmi handler uses the fact that crossing a zero means the counter overflowed (for those counters that do not have specific interrupt bits). ...
