Vhost is a kernel-level backend for virtio. This patch add a nic_param
named vhost to enable/disable vhost backend.
Changes from v3:
- Added comment explaining that the feature only works with nic_mode =
tap.
- Instead of commenting out the option vhost, leave it uncommented but
with default

Vhost-net backend is only valid when we use tap, so it should work with

In QEMU-KVM, physical address != RAM address. While MCE simulation
needs physical address instead of RAM address. So
kvm_physical_memory_addr_from_ram() is implemented to do the
conversion, and it is invoked before being filled in the IA32_MCi_ADDR
MSR.
Port qemu-kvm's KVM MCE (Machine Check Exception) handling to qemu. It
allows qemu to propagate MCEs to the guest.

- rename do_qemu_ram_addr_from_host.
- fix kvm_on_sigbus/kvm_on_sigbus_vcpu naming.
- fix bank register restoration (Dean Nelson).
v3:
- condition MCE generation on MCE_SEG_P
Please send in any agenda items you are interested in covering.
