This updates x86's kvm_para.h for the feature bit definition and
target-i386/cpu.c for the feature name and default.

Thanks, looks good---assuming the kernel side will make it into 3.17,
I'll sync the headers once 3.17 is released and then apply the patch.
As mentioned in kvm@ someone will have to add the pc-2.2 machine type too.
