Cover letter [RFC][PATCH 0/4] Enabled NMI support for KVM

This patchset enabled NMI support for KVM.

The first three patches enabled NMI for in-kernel irqchip and NMI supporting on VMX. The last patch enabled NMI watchdog in linux, can be used to test the NMI injection.

In fact, this series should also included Jan Kiszka's patch to enable NMI for userspace irqchip, but now I got little trouble to get the merged version work on my machine... We would post it as soon as we solved it.

Another thing is the vmx_intr_assist() and do_interrupt_requests() got some duplication. And the logic for normal interrupt and NMI is similiar, but vmx_intr_assist() seems a little implicit...

Any comments welcome!
