- MCE features are initialized when VCPU is intialized according to CPUID.
- A monitor command mce is added to inject a MCE.
- A new interrupt mask: CPU_INTERRUPT_MCE is added to inject the MCE.
ChangeLog:
v5:
- Rebased on latest qemu-kvm.git
v4:
- Add savevm/loadvm support

Minor issues that likely had no practical relevance: The kvm timer

1. Consider making all the cloned VMs use image snapshots:

I'm not sure it's a good idea to let all VMs use the same disk image.
Or maybe you shouldn't add -snapshot yourself,

Currently vcpu_id is used as an index into vcpus array and as apic id
on x86. This is incorrect since apic ids not have to be continuous
(they can also encode cpu hierarchy information) and may have values
bigger then vcpu array in case of x2apic. This series removes use of
vcpu_id as vcpus array
Archs are free to use vcpu_id as they see fit. For x86 it is used as
vcpu's apic id. New ioctl is added to configure boot vcpu id that was
assumed to be 0 till now.
