KVM: x86: Enable NMI Watchdog via in-kernel PIT source
LINT0 of the LAPIC can be used to route PIT events as NMI watchdog ticks
into the guest. This patch aligns the in-kernel irqchip emulation with
the user space irqchip with already supports this feature. The trick is
to route PIT interrupts to all LAPIC's LVT0 lines.
Rebased and slightly polished patch originally posted by Sheng Yang.
