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.

Ok, fair enough, that's what I've done
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
The only bit of EFER that affects the mmu is NX, and this is already
accounted for (LME only takes effect when changing cr0).
Based on a patch by Hillf Danton.
