Cover letter [PATCH 0/2] NMI supporting for KVM and VMX v2

Hi

Sorry for the update delays, got a cold recently...

No big modification. I dropped the ordinary first patch following Avi's comment, and fixed a bug when handling host NMI in vmx_vcpu_run in second patch.

The third patch of enabling NMI watchdog is *not* meant to be merged. It was cooked for the test, and it would bring some overhead on interrupt handling, as well as regression on some version of Windows now(IRQ_NOT_EQUAL_OR_LESS BSOD). But is it necessary to got NMI watchdog support in KVM? If so, maybe we need a option(or kernel module parameter) to enable it.

Thanks
